A-10/OA-10 Thunderbolt II
Function: The A-10 and OA-10 Thunderbolt IIs are the first Air Force aircraft specially designed for close air support of ground forces. They are simple, effective and survivable twin-engine jet aircraft that can be used against all ground targets, including tanks and other armored vehicles.
History: The first production A-10A was delivered to Davis-Monthan Air Force Base, AZ, in October 1975. It was designed specially for the close air support mission and had the ability to combine large military loads, long loiter and wide combat radius, which proved to be vital assets to America and its allies during Operation Desert Storm. In the Gulf War, A-10s, with a mission capable rate of 95.7 percent, flew 8,100 sorties and launched 90 percent of the AGM-65 Maverick missiles.
Description: The A-10/OA-10 have excellent maneuverability at low air speeds and altitude, and are highly accurate weapons-delivery platforms. They can loiter near battle areas for extended periods of time and operate under 1,000-foot ceilings (303.3 meters) with 1.5-mile (2.4 kilometers) visibility. Their wide combat radius and short takeoff and landing capability permit operations in and out of locations near front lines. Using night vision goggles, A-10/ OA-10 pilots can conduct their missions during darkness.
Thunderbolt IIs have Night Vision Imaging Systems (NVIS), compatible single-seat cockpits forward of their wings and a large bubble canopy which provides pilots all-around vision. The pilots are encircled by titanium armor that also protects parts of the flight-control system. The redundant primary structural sections allow the aircraft to enjoy better survivability during close air support than did previous aircraft. The aircraft can survive direct hits from armor-piercing and high-explosive projectiles up to 23mm. Their self-sealing fuel cells are protected by internal and external foam. Their redundant hydraulic flight-control systems are backed up by manual systems. This permits pilots to fly and land when hydraulic power is lost.
The Thunderbolt II can be serviced and operated from bases with limited facilities near battle areas. Many of the aircraft's parts are interchangeable left and right, including the engines, main landing gear and vertical stabilizers.
Avionics equipment includes communications, inertial navigation systems, fire control and weapons delivery systems, target penetration aids and night vision goggles. Their weapons delivery systems include head-up displays that indicate airspeed, altitude and dive angle on the windscreen, a low altitude safety and targeting enhancement system (LASTE) which provides constantly computing impact point freefall ordnance delivery; and Pave Penny laser-tracking pods under the fuselage. The aircraft also have armament control panels, and infrared and electronic countermeasures to handle surface-to-air-missile threats.
The Thunderbolt II's 30mm GAU-8/A Gatling gun can fire 3,900 rounds a minute and can defeat an array of ground targets to include tanks. Some of their other equipment includes an inertial navigation system, electronic countermeasures, target penetration aids, self-protection systems, and AGM-65 Maverick and AIM-9 Sidewinder missiles.

Mark 67 Submarine Launche
Description: A Mk 67 Submarine Launched Magnetic Mine (SLMM) weighs approximately 1,790 pounds and is launched from submerged submarines. The SLMM propels itself to the planting site where it shuts down and plants itself until recovery. Approximately twenty seconds after the end of the run, all propulsion and control functions are shut down and the fuse ejector disconnects the main motor fuse disconnect. This action prevents the motor from restarting after planting.
The Service SLMM is a self-propelled bottom mine with a capability that permits it to be covertly placed in a predetermined bottom planting location. It uses a Target Detection Device (TDD) Mk 57 that utilizes magnetic and seismic sensors to detect stimuli generated by enemy vessels. The SLMM's purpose is to restrict ship and submarine traffic in an operational role. The Service SLMM employs a modified Torpedo Mk 37 as the propulsion vehicle, designated the Body, Mine Main Assembly Mk 4. Forward of this main body is the Explosive Section Mk 13/Nose Section Subassembly (Loaded) which contains the PBXN?103 explosive mixture, Exploder Mechanism Mk 19, Arming Device Mk 2, and TDD Mk 57 with its Battery Mk 131.
The Body, Mine Main Assembly Mk 4 is painted green, while the Explosive Section Mk 13 retains its galvanized finish.
The training SLMM is used to provide a means for submarine personnel to develop the proficiency required to plant the mine in a minefield. The training SLMM also uses the Body, Mine Main Assembly Mk 4 for propulsion, modified so it does not flood at end of run and so the energized training battery does not run the propulsion motor when first mated to the main body. The Body, Mine Main Assembly Mk 4 is painted green, while the Inert Loaded Explosive Section Mk 13 or Exercise Head Assembly Mk 91 is painted either white with orange stripes or orange with white stripes.

M1A2 MBT
The mission of the M1A2 Abrams tank is to close with and destroy enemy forces using firepower, maneuver, and shock effect. The M1A2 is being fielded to armor battalions and cavalry squadrons of the heavy force. In lieu of new production, the Army is upgrading approximately 1,000 older M1 tanks to the M1A2 configuration. Going from the M1A1 to M1A2, the Army did several things that significantly reduced ballistic vulnerability, adding dual, redundant harnesses components, redundant data buses, distributing electrical power systems so all the power controls are not in one place.
During the Army's current M1A2 procurement program about 1,000 older, less capable M1 series tanks will be upgraded to the M1A2 configuration and fielded to the active forces. There is currently no plan to field the M1A2 to the ARNG. The Army has procured 62 new tanks in the A2 configuration and as of early 1997 completed the conversion of 368 older M1s to M1A2s. The first three years of M1A2 Abrams upgrade tank work, between 1991-1993, delivered 267 tanks. A multi-year procurement of 600 M1A2 upgrade tanks was run at Lima [Ohio] Army tank plant from 1996 to 2001.
Further M1A2 improvements, called the System Enhancement Program (SEP), are underway to enhance the tank's digital command and control capabilities and to to improve the tank's fightability and lethality. In FY 1999, the Army began upgrading M1s to the M1A2 System Enhancement Program (SEP) configuration. In 1994, the Army awarded a contract to General Dynamics Land Systems to design system enhancements to the M1A2, and awarded GDLS another contact in 1995 to supply 240 of the enhanced M1A2s, with delivery scheduled to begin in 1999. M1A2 SEP started fielding in 2000. It adds second generation forward looking infrared technology to the gunner's and commander's thermal sights. This sensor also will be added to older M1A2s starting in FY 2001.
A multi-year contract for 307 M1A2 Abrams Systems Enhancement Program (SEP) tanks was awarded in March 2001 with production into 2004. The current Army plan allows for a fleet of 588 M1A2 SEP, 586 M1A2 and 4,393 M1A1 tanks. The potential exits for a retrofit program of 129 M1A2 tanks to the SEP configuration between 2004 and 2005. Initial fielding of the M1A2 to the Army's 1st Cavalry Division, Fort Hood, Texas, was complete by August 1998. Fielding to the 3rd Armored Cavalry Regiment, Ft. Carson, Colorado ended in 2000. Fielding of the M1A2 (SEP) began in spring 2000 with the 4th Infantry Division, Fort Hood, Texas, and continues. Rolling over of the 1st Cavalry Division's M1A2 tanks to new M1A2 (SEP) tank began in 2001 and continues.
The M1A2 SEP (System Enhancement Package), is the digital battlefield centerpiece for Army XXI. It is the heavy force vehicle that will lead Armor into the next century and transition the close combat mission to the Future Combat System (FCS). The M1A2 SEP is an improved version of the M1A2. It contains numerous improvements in command and control, lethality and reliability. The M1A2 System Enhanced Program is an upgrade to the computer core that is the essence of the M1A2 tank. The SEP upgrade includes improved processors, color and high resolution flat panel displays, increased memory capacity, user friendly Soldier Machine Interface (SMI) and an open operating system that will allow for future growth. Major improvements include the integration of the Second Generation Forward Looking Infared (2nd Gen FLIR) sight, the Under Armor Auxiliary Power Unit (UAAPU) and a Thermal Management System (TMS).
Increased funding for Stryker and Future Combat Systems (FCS) came as a result of Army decisions in 2002 to terminate or restructure some 48 systems in the FY '04 - '09 Program Objective Memorandum (POM) long-term spending plan. Among the systems terminated were: United Defense's Crusader self-propelled howitzer and the A3 upgrade for the Bradley Fighting vehicle, GD's M1A2 Abrams System Enhancement Program, Lockheed Martin's Army Tactical Missile System Block II and the associated pre-planned product improvement version of Northrop Grumman's Brilliant Anti-armor (BAT) munition, Raytheon's Stinger missile and Improved Target Acquisition System, and Textron's Wide Area Mine.
The 2nd Generation Forward Looking InfraRed sighting system (2nd Gen FLIR) will replace the existing Thermal Image System (TIS) and the Commander's Independent Thermal Viewer. The incorporation of 2nd Gen FLIR into the M1A2 tank will require replacement of all 1st Gen FLIR components. From the warfighter perspective, this is one of the key improvements on the SEP. The 2nd Gen FLIR is a fully integrated engagement-sighting system designed to provide the gunner and tank commander with significantly improved day and night target acquisition and engagement capability. This system allows 70% better acquisition, 45% quicker firing and greater accuracy. In addition, a gain of 30% greater range for target acquisition and identification will increase lethality and lessen fratricide. The Commander's Independent Thermal Viewer (CITV) provides a hunter killer capability. The 2nd GEN FLIR is a variable power sighting system ranging from 3 or 6 power (wide field of view) for target acquisition and 13, 25 or 50 power (narrow field of view) for engaging targets at appropriate range.
The UAAPU consist of a turbine engine, a generator, and a hydraulic pump. The generator is capable of producing 6 Kilowatts of electrical power at 214 Amps, 28 vdc, and the hydraulic pump is capable of delivering 10 Kilowatts of hydraulic power. The UAAPU can meet the electrical and hydraulic power to operate all electronic and hydraulic components used during mounted surveilance operations and charge the tank's main batteries. The UAAPU will reduce Operational and Support cost by utilizing the same fuel as the tank at a reduced rate of 3-5 gallons per operational hour. The UAAPU is mounted on the left rear sponson fuel cell area and weighs 510 pounds.
Another improvement in the M1A2 SEP is the Thermal Management System (TMS) which keeps the temperature within the crew compartment under 95 degrees and the touch temperature of electronic units under 125 degrees during extreme conditions. By reducing the temperature in the crew compartment for the crew and electronic units, this increases the operational capability for both soldiers and the vehicle. The TMS consists of an Air Handling Unit (AHU) and a Vapor Compression System Unit (VCSU) capable of providing 7.5 Kilowatts of cooling capacity for the crew and Line Repairable Units (LRUs). The AHU is mounted in the turret bustle and the VCSU is mounted forward of the Gunner's Primary Sight (GPS). The TMS uses enviromentally friendly R134a refrigerant and propylene glycol/water mixture to maintain the LRU touch temperature at less than 140 degrees Fahrenheit. The TMS is mounted in the left side of turret bussel and weighs 384 pounds.
The Army requires that all systems operate in the Army Common Operating Environment (ACOE) to improve combined arms operations. Digitization and information dominance across the entire Army for tactical elements is accomplished using Force XXI Battle Command for Brigade and Below (FBCB2) software. In Abrams, FBCB2 software is hosted on a separate card that enables situational awareness across the entire spectrum of tactical operation. It improves message flow, through 34 joint variable message formats, reports ranging from contact reports to logistic roll ups, as well as automatically providing vehicle location to friendly systems. The SEP allows for digital data dissemination with improved ability to optimize information based operations and maintain a relevant common picture while executing Force XXI full dimensional operation. This enhancement increases capability to control the battlefield tempo while improving lethality and survivability. Finally to ensure crew proficiency is maintained, each Armor Battalion is fielded an improved Advanced Gunnery Training System (AGTS) with state-of-the-art graphics.
Changes to the M1A2 Abrams Tank contained in the System Enhancement Program (SEP) and "M1A2 Tank FY 2000" configuration are intended to improve lethality, survivability, mobility, sustainability and provide increased situational awareness and command & control enhancements necessary to provide information superiority to the dominant maneuver force. The Abrams Tank and the Bradley Fighting Vehicle are two central components of the dominant maneuver digital force.
System Enhancement Program upgrades are intended to:
improve target detection, recognition and identification with the addition of two 2nd generation FLIRs.
incorporate an under armor auxiliary power unit to power the tank and sensor suites.
incorporate a thermal management system to provide crew and electronics cooling.
increase memory and processor speeds and provide full color map capability.
provide compatibility with the Army Command and Control Architecture to ensure the ability to share command & control and situational awareness with all components of the combined arms team.
Additional weight reduction, embedded battle command, survivability enhancement, signature management, safety improvement, and product upgrade modifications to the M1A2 will comprise the "M1A2 Tank FY 2000" configuration fielded to units of the digital division beginning in FY 2000.
The M1A2 IOT&E was conducted from September-December 1993 at Fort Hood, TX and consisted of a gunnery phase and a maneuver phase. The Director determined that the test was adequate, the M1A2 was operationally effective, but not operationally suitable and unsafe. That assessment was based on poor availability and reliability of the tank, instances of the uncommanded tube and turret movement, inadvertent .50 caliber machine gun firing, and hot surfaces which caused contact burns.
FOT&E #1 was conducted in September-October 1995 in conjunction with the New Equipment Training for two battalion sized units. Despite assurances from the Army that all corrective actions were applied, numerous instances of uncommanded tube and turret movement, Commander's Independent Display (CID) lockup and contact burns continued during FOT&E #1. The follow-on test was placed on hold and the Army "deadlined" the two battalions of M1A2 tanks at Fort Hood for safety reasons. The PM isolated 30 "root causes" of the safety problems and completed hardware and software upgrades in June 1996 which were assessed in FOT&E #2.
The M1A2 TEMP was approved during 2QFY98. This TEMP includes a coordinated plan for FOT&E #3 of the M1A2 in conjunction with the IOT&E of the Bradley Fighting Vehicle in FY99 at Fort Hood, TX. This combined operational test will consist of 16 force-on-force battles between a Bradley Fighting Vehicle System-A3/M1A2 SEP combined arms team and M1A1/ Bradley-ODS combined arms team. Additionally, it will serve as the operational test for the 2d Generation FLIR. This approach implements the Secretary of Defense theme of combining testing in order to save resources and ensure a more realistic operational environment.
The Army and DOT&E completed vulnerability assessment efforts and concluded that the "M1A2 Tank FY 2000" is a significant change from the original M1A2 design and will require a system-level survivability evaluation. This evaluation will rely on full-up system level testing of two systems, component and sub-system level testing, modeling and simulation, existing data, and previous testing to assess susceptibility and vulnerability of the "M1A2 Tank FY 2000" and its crew to the expected threat and to assess battle damage repair capabilities.
The M1A2 Abrams Tank with the corrective actions applied by the Program Manager during FY96 is assessed to be operationally effective and suitable. The availability, reliability, fuel consumption, and safety problems observed in previous testing have been corrected. FOT&E #2 was adequately conducted in accordance with approved test plans and the Abrams TEMP. There were no observed instances of the uncommanded tube and turret movement, inadvertent .50 caliber machine gun firing, and hot surfaces which caused contact burns in previous testing.
The largest area of technical risk to the program is the development of the Embedded Battle Command software which is intended to provide friendly and enemy situational awareness and shared command & control information throughout the combined arms team. This software is being developed as a Horizontal Technology Insertion program and will be provided to the weapon systems and C2 nodes of the combined arms team in FY00. This development schedule is high risk and could adversely impact the M1A2 schedule.
In late 2002 the Army experienced a tragic accident involving the M1A2 Abrams main battle tank. While the crew of the M1A2 was operating the vehicle, a failure within the vehicle's Nuclear, Biological, Chemical (NBC) main system occurred which resulted in an NBC filter fire. One soldier died and 9 others received injuries. While there are numerous factors involved in this accident, the primary cause of the NBC Filter fire is an air cycle machine seizure, caused by dirt ingestion.
The M1A2 tank provides various warnings and cautions to crewmembers in the case of an NBC system problem. These warnings and cautions are displayed visually at the Commander's Integrated Display (CID) and at the Driver's Integrated Display (DID); additionally, an Audio tone is transmitted to each crewman via the Vehicular Intercommunication Set (VIS). The audio warning is generated from the tank's Analog Input Module (AIM) by way of the 2W119-5 wiring harness (Y-cable) which is connected to the driver's station, full-function, control box (AN/VIC 3). This Y-cable must be connected to the driver's control box at the J3 connector with the driver's CVC plugged into the P4 end of the Y-cable. Failure to properly hookup the 2W119-5 cable will not interfere with vehicle communications, but it will result in NO NBC warning tone being heard. In addition to the accident vehicle, several other M1A2 tanks at this installation were found to have the same incorrect connection. Commanders should ensure that each M1A2 in their command is inspected to ensure that this system is correctly connected. The NBC system should not be used until the inspection is complete.
If an NBC warning message is given (visually or audio), crews should immediately press NBC MAIN pushbutton on the CID to turn off the NBC main system. Continued use of the NBC main system will result in an NBC filter fire.
The NBC system is a critical component of the M1A2; it provides crews with increased protection when operating in a combat environment. This system requires proper servicing and checks as outlined in the technical manual. Ensure that all NBC sponson bolts and hardware are properly mounted and secure at all times. Failure to do so can result in the build up of dirt and dust within the NBC sponson box with the potential of damaging the Air Cycle Machine (ACM) and other components.

This combined operational test will consist of 16 force-on-force battles between a Bradley Fighting Vehicle System-A3/M1A2 SEP combined arms team and M1A1/ Bradley-ODS combined arms team. Additionally, it will serve as the operational test for the 2d Generation FLIR. This approach implements the Secretary of Defense theme of combining testing in order to save resources and ensure a more realistic operational environment.
The Army and DOT&E completed vulnerability assessment efforts and concluded that the "M1A2 Tank FY 2000" is a significant change from the original M1A2 design and will require a system-level survivability evaluation. This evaluation will rely on full-up system level testing of two systems, component and sub-system level testing, modeling and simulation, existing data, and previous testing to assess susceptibility and vulnerability of the "M1A2 Tank FY 2000" and its crew to the expected threat and to assess battle damage repair capabilities.
The M1A2 Abrams Tank with the corrective actions applied by the Program Manager during FY96 is assessed to be operationally effective and suitable. The availability, reliability, fuel consumption, and safety problems observed in previous testing have been corrected. FOT&E #2 was adequately conducted in accordance with approved test plans and the Abrams TEMP. There were no observed instances of the uncommanded tube and turret movement, inadvertent .50 caliber machine gun firing, and hot surfaces which caused contact burns in previous testing.
The largest area of technical risk to the program is the development of the Embedded Battle Command software which is intended to provide friendly and enemy situational awareness and shared command & control information throughout the combined arms team. This software is being developed as a Horizontal Technology Insertion program and will be provided to the weapon systems and C2 nodes of the combined arms team in FY00. This development schedule is high risk and could adversely impact the M1A2 schedule.
In late 2002 the Army experienced a tragic accident involving the M1A2 Abrams main battle tank. While the crew of the M1A2 was operating the vehicle, a failure within the vehicle's Nuclear, Biological, Chemical (NBC) main system occurred which resulted in an NBC filter fire. One soldier died and 9 others received injuries. While there are numerous factors involved in this accident, the primary cause of the NBC Filter fire is an air cycle machine seizure, caused by dirt ingestion.
The M1A2 tank provides various warnings and cautions to crewmembers in the case of an NBC system problem. These warnings and cautions are displayed visually at the Commander's Integrated Display (CID) and at the Driver's Integrated Display (DID); additionally, an Audio tone is transmitted to each crewman via the Vehicular Intercommunication Set (VIS). The audio warning is generated from the tank's Analog Input Module (AIM) by way of the 2W119-5 wiring harness (Y-cable) which is connected to the driver's station, full-function, control box (AN/VIC 3). This Y-cable must be connected to the driver's control box at the J3 connector with the driver's CVC plugged into the P4 end of the Y-cable. Failure to properly hookup the 2W119-5 cable will not interfere with vehicle communications, but it will result in NO NBC warning tone being heard. In addition to the accident vehicle, several other M1A2 tanks at this installation were found to have the same incorrect connection. Commanders should ensure that each M1A2 in their command is inspected to ensure that this system is correctly connected. The NBC system should not be used until the inspection is complete.
If an NBC warning message is given (visually or audio), crews should immediately press NBC MAIN pushbutton on the CID to turn off the NBC main system. Continued use of the NBC main system will result in an NBC filter fire.
The NBC system is a critical component of the M1A2; it provides crews with increased protection when operating in a combat environment. This system requires proper servicing and checks as outlined in the technical manual. Ensure that all NBC sponson bolts and hardware are properly mounted and secure at all times. Failure to do so can result in the build up of dirt and dust within the NBC sponson box with the potential of damaging the Air Cycle Machine (ACM) and other components.

BGM-71 / M-220 Tube-launc
The TOW anti-tank missile of Iran-Contra fame was introduced for service in the US Army in 1970. Current versions are capable of penetrating more than 30 inches of armor, or "any 1990s tank," at a maximum range of more than 3,000 meters. It can be fired by infantrymen using a tripod, as well from vehicles and helicopters, and can launch 3 missiles in 90 seconds. It is primarily used in antitank warfare, and is a command to line of sight, wire-guided weapon. TOW is used to engage and destroy enemy armored vehicles, primarily tanks. Secondary mission is to destroy other point targets such as non-armored vehicles, crew-served weapons and launchers. This system is designed to attack and defeat tanks and other armored vehicles. The system will operate in all weather conditions and on the "dirty" battlefield.
In May 1972, U.S. soldiers initially used the TOW in combat during the Vietnam War. This was the very first time that American troops had ever fired an American-made missile under wartime conditions. The system has also seen action in various clashes between Israel and Syria as well as during the Iran/Iraq war. During the Gulf War, in Saudi Arabia the system was represented by the HMMWV with the light forces, the Bradley Fighting Vehicle with the heavy forces, Improved TOW Vehicle with some of the forces, and the Cobra-mounted version. The TOW was one of the earliest missile systems to arrive in SWA because of the large Iraqi armored threat it was deployed with some of the first units in Saudi: the 82nd Airborne Division, the 24th Mechanized Division and the101st Airborne Division. Thousands of missiles and hundreds of launchers were used during Operation Desert Storm. Forces of other countries, including Saudi Arabia, also had TOW at their disposal.
Early reports focused on the problems being experienced by US Army and Marine Corps units in hitting targets during live-fire exercises because soldiers [lacked experience firing the weapon, as well as Iraqi use of "dazzlers" intended to interfere with the guidance of Army TOW missiles and other antitank missiles. But the TOW during ODS was a primary killer of Iraqi tanks, armored personnel carriers,and other vehicles. Before the start of the coalition air campaign in January 1991, Army and Marine Corps planners noted a trend of improvement as more and more units [had] the opportunity to practice firing the TOW. The Iraqi use of dazzlers also proved to be of little concern to coalition commanders. The purpose of the dazzler is to confuse the missile guidance system so it loses track of the missile. It did not work against the TOWs used in Southwest Asia. There were no reports since the war that any of these were effective in any way against TOWs.
Before the start of the actual ground offensive, US Marine units successfully employed the TOW against various Iraqi targets. On 18 January 1991, newspapers reported that U.S. Marine Corps AH-1T Cobra helicopter gunships destroyed an Iraqi command post following Iraq's sporadic shelling of the Khafji area near the Saudi-Kuwaiti border. Four Cobra gunships destroyed a building used as an Iraqi command post with TOW missiles. Accounts told by Gulf War veterans who witnessed the TOW in action during the fighting revealed several instances where TOWs did things that surprised the engineers who designed them more than the soldiers who fired them. TOW missiles proved to be a determining factor in the first ground engagement of Operation Desert Storm. During the Battle of Khafji, which took place before the start of the actual ground offensive, the TOW demonstrated a pretty unique ability. The Saudis fought Iraqi tanks with TOW missiles and drove them out of the city. At one point in the battle, the Saudis saw Iraqi soldiers on top of a water tower. Not wishing to blow up the tower, the Saudis fired a TOW, blew the ladder off the tower and left the Iraqis stranded until the end of the battle." The lethality of the TOW missile was proven beyond doubt during the 100-hour ground campaign when one of the antitank munitions fired by US troops went right through the tank it was aimed at and penetrated another tank parked next to it. Another TOW went through a six foot dirt berm and knocked out an Iraqi armored personnel carrier on the otherside. In both instances, the TOW performed a feat which it supposedly was incapable of accomplishing.
Even without these rather unusual and certainly unexpected displays of its effectiveness, the TOW did better than expected. The system's deadly accuracy proved to be unstoppable even out to its maximum effective range and under degraded visibility conditions. TOW was real powerful hitting because you could tell as soon as it hit, the vehicle was dead. TOW missiles were able to kill targets while the Bradley was on the move.
The basic TOW Weapon System was fielded in 1970. Manufactured by Hughes Aircraft Company, the TOW is the most widely distributed anti-tank guided missile in the world with over 500,000 built and in service in the U.S. and 36 other countries. The TOW has extensive combat experience in Vietnam and the Middle East. Iran may have obtained 1,750 or more TOWs and used TOWs against Iraqi tanks in the 1980s. The TOW 2 launcher is the most recent launcher upgrade. It is compatible with all TOW missiles. The TOW 2 Weapon System is composed of a reusable launcher, a missile guidance set, and sight system. The system can be tripod mounted. However because it is heavy, it is generally employed from the HMMWV. The missile has a 20-year maintenance-free storage life. All versions of the TOW missile can be fired from the current launcher.
The TOW is a crew portable, vehicle-mounted, heavy anitarmor weapon system consisting of a launcher and one of five versions of the TOW missile. It is designed to defeat armored vehicles and other targets such as field fortifications from ranges up to 3,750 meters. After firing the missile, the gunner must keep the cross hairs of the sight centered on the target to ensure a hit. The system will operate in all weather conditions in which the gunner can see a target throughout the missile flight by using either a day or night sight.
The TOW Sight Improvement Program (TSIP) effort began in 199 However, on 15 October 1991 The Secretary of the Army cancelled the TSIP because of declining budget & funding issues. The Assistant Secretary of the Army for Research, Development and Acquisition directed the PEO, Tactical Missiles to coordinate the development of an affordable alternative. The latter effort subsequently became known as the Improved Target Acquisition System (ITAS) being developed for the Army's light forces.
The TOW Improved Target Acquisition System (ITAS) is a materiel change to the The ITAS is a material change to the current TOW2 ground launcher and M966 HMMWV TOW2 acquisition and fire control subsystems for first-to-deploy light forces. ITAS aides in firing all versions of TOW and builds the bridge to TOW F&F. The TOW tripod and launch tube remain unchanged. ITAS significantly increases target acquisition and engagement ranges, while retaining the capability to fire all configurations of the TOW missile. ITAS uses a second-generation forward-looking infrared system, digital components, and an eyesafe laser range finder. ITAS has an improved design with BIT/ BITES for increased maintainability and reduced logistics requirements. It also features an improved man-machine interface that improves system engagement performance. The ITAS modification kit consists of an integrated (Day/ Night Sight with Laser Rangefinder) Target Acquisition Subsystem (TAS), Fire Control Subsystem (FCS), Battery Power Source (BPS), and Modified Traversing Unit (TU). The ITAS will operate from the High Mobility Multi- Purpose Wheeled Vehicle (HMMWV) and the dismount tripod platform. The ITAS will be fielded at battalion level, replacing TOW 2 in light infantry units. The TOW Improved Target Acquisition System low- rate initial production (LRIP) I contract was awarded September 30, 1996, with a production quantity of twenty- five units. LRIP II was awarded March 1998 for a quantity of seventy-three systems for the 1st BDE Fielding in September 1999. First unit equipped (FUE) was conducted in September 1998.
Increased funding for Stryker and Future Combat Systems (FCS) came as a result of Army decisions in 2002 to terminate or restructure some 48 systems in the FY ?04-?09 Program Objective Memorandum (POM) long-term spending plan. Among the systems terminated were: United Defense?s Crusader self-propelled howitzer and the A3 upgrade for the Bradley Fighting vehicle, GD?s M1A2 Abrams System Enhancement Program, Lockheed Martin?s Army Tactical Missile System Block II and the associated pre-planned product improvement version of Northrop Grumman?s Brilliant Anti-armor (BAT) munition, Raytheon?s Stinger missile and Improved Target Acquisition System, and Textron?s Wide Area Mine.
The TOW system is used on the HMMWV, the M151 jeep, the armored personnel carrier, the Bradley Fighting Vehicle (BFV) COBRA helicopters, the ITV, and the US Marine Corps light armored vehicle.
Considerable improvements have been made to the missile since 1970. There are six missiles available for the TOW. Three of the five TOW missile versions--Basic TOW, Improved TOW and TOW 2--are no longer being produced for US forces. However, these versions are still used by 40 allied countries.

BGM-71 / M-220 Tube-launc
The TOW anti-tank missile of Iran-Contra fame was introduced for service in the US Army in 1970. Current versions are capable of penetrating more than 30 inches of armor, or "any 1990s tank," at a maximum range of more than 3,000 meters. It can be fired by infantrymen using a tripod, as well from vehicles and helicopters, and can launch 3 missiles in 90 seconds. It is primarily used in antitank warfare, and is a command to line of sight, wire-guided weapon. TOW is used to engage and destroy enemy armored vehicles, primarily tanks. Secondary mission is to destroy other point targets such as non-armored vehicles, crew-served weapons and launchers. This system is designed to attack and defeat tanks and other armored vehicles. The system will operate in all weather conditions and on the "dirty" battlefield.
In May 1972, U.S. soldiers initially used the TOW in combat during the Vietnam War. This was the very first time that American troops had ever fired an American-made missile under wartime conditions. The system has also seen action in various clashes between Israel and Syria as well as during the Iran/Iraq war. During the Gulf War, in Saudi Arabia the system was represented by the HMMWV with the light forces, the Bradley Fighting Vehicle with the heavy forces, Improved TOW Vehicle with some of the forces, and the Cobra-mounted version. The TOW was one of the earliest missile systems to arrive in SWA because of the large Iraqi armored threat it was deployed with some of the first units in Saudi: the 82nd Airborne Division, the 24th Mechanized Division and the101st Airborne Division. Thousands of missiles and hundreds of launchers were used during Operation Desert Storm. Forces of other countries, including Saudi Arabia, also had TOW at their disposal.
Early reports focused on the problems being experienced by US Army and Marine Corps units in hitting targets during live-fire exercises because soldiers [lacked experience firing the weapon, as well as Iraqi use of "dazzlers" intended to interfere with the guidance of Army TOW missiles and other antitank missiles. But the TOW during ODS was a primary killer of Iraqi tanks, armored personnel carriers,and other vehicles. Before the start of the coalition air campaign in January 1991, Army and Marine Corps planners noted a trend of improvement as more and more units [had] the opportunity to practice firing the TOW. The Iraqi use of dazzlers also proved to be of little concern to coalition commanders. The purpose of the dazzler is to confuse the missile guidance system so it loses track of the missile. It did not work against the TOWs used in Southwest Asia. There were no reports since the war that any of these were effective in any way against TOWs.
Before the start of the actual ground offensive, US Marine units successfully employed the TOW against various Iraqi targets. On 18 January 1991, newspapers reported that U.S. Marine Corps AH-1T Cobra helicopter gunships destroyed an Iraqi command post following Iraq's sporadic shelling of the Khafji area near the Saudi-Kuwaiti border. Four Cobra gunships destroyed a building used as an Iraqi command post with TOW missiles. Accounts told by Gulf War veterans who witnessed the TOW in action during the fighting revealed several instances where TOWs did things that surprised the engineers who designed them more than the soldiers who fired them. TOW missiles proved to be a determining factor in the first ground engagement of Operation Desert Storm. During the Battle of Khafji, which took place before the start of the actual ground offensive, the TOW demonstrated a pretty unique ability. The Saudis fought Iraqi tanks with TOW missiles and drove them out of the city. At one point in the battle, the Saudis saw Iraqi soldiers on top of a water tower. Not wishing to blow up the tower, the Saudis fired a TOW, blew the ladder off the tower and left the Iraqis stranded until the end of the battle." The lethality of the TOW missile was proven beyond doubt during the 100-hour ground campaign when one of the antitank munitions fired by US troops went right through the tank it was aimed at and penetrated another tank parked next to it. Another TOW went through a six foot dirt berm and knocked out an Iraqi armored personnel carrier on the otherside. In both instances, the TOW performed a feat which it supposedly was incapable of accomplishing.
Even without these rather unusual and certainly unexpected displays of its effectiveness, the TOW did better than expected. The system's deadly accuracy proved to be unstoppable even out to its maximum effective range and under degraded visibility conditions. TOW was real powerful hitting because you could tell as soon as it hit, the vehicle was dead. TOW missiles were able to kill targets while the Bradley was on the move.
The basic TOW Weapon System was fielded in 1970. Manufactured by Hughes Aircraft Company, the TOW is the most widely distributed anti-tank guided missile in the world with over 500,000 built and in service in the U.S. and 36 other countries. The TOW has extensive combat experience in Vietnam and the Middle East. Iran may have obtained 1,750 or more TOWs and used TOWs against Iraqi tanks in the 1980s. The TOW 2 launcher is the most recent launcher upgrade. It is compatible with all TOW missiles. The TOW 2 Weapon System is composed of a reusable launcher, a missile guidance set, and sight system. The system can be tripod mounted. However because it is heavy, it is generally employed from the HMMWV. The missile has a 20-year maintenance-free storage life. All versions of the TOW missile can be fired from the current launcher.
The TOW is a crew portable, vehicle-mounted, heavy anitarmor weapon system consisting of a launcher and one of five versions of the TOW missile. It is designed to defeat armored vehicles and other targets such as field fortifications from ranges up to 3,750 meters. After firing the missile, the gunner must keep the cross hairs of the sight centered on the target to ensure a hit. The system will operate in all weather conditions in which the gunner can see a target throughout the missile flight by using either a day or night sight.
The TOW Sight Improvement Program (TSIP) effort began in 199 However, on 15 October 1991 The Secretary of the Army cancelled the TSIP because of declining budget & funding issues. The Assistant Secretary of the Army for Research, Development and Acquisition directed the PEO, Tactical Missiles to coordinate the development of an affordable alternative. The latter effort subsequently became known as the Improved Target Acquisition System (ITAS) being developed for the Army's light forces.
The TOW Improved Target Acquisition System (ITAS) is a materiel change to the The ITAS is a material change to the current TOW2 ground launcher and M966 HMMWV TOW2 acquisition and fire control subsystems for first-to-deploy light forces. ITAS aides in firing all versions of TOW and builds the bridge to TOW F&F. The TOW tripod and launch tube remain unchanged. ITAS significantly increases target acquisition and engagement ranges, while retaining the capability to fire all configurations of the TOW missile. ITAS uses a second-generation forward-looking infrared system, digital components, and an eyesafe laser range finder. ITAS has an improved design with BIT/ BITES for increased maintainability and reduced logistics requirements. It also features an improved man-machine interface that improves system engagement performance. The ITAS modification kit consists of an integrated (Day/ Night Sight with Laser Rangefinder) Target Acquisition Subsystem (TAS), Fire Control Subsystem (FCS), Battery Power Source (BPS), and Modified Traversing Unit (TU). The ITAS will operate from the High Mobility Multi- Purpose Wheeled Vehicle (HMMWV) and the dismount tripod platform. The ITAS will be fielded at battalion level, replacing TOW 2 in light infantry units. The TOW Improved Target Acquisition System low- rate initial production (LRIP) I contract was awarded September 30, 1996, with a production quantity of twenty- five units. LRIP II was awarded March 1998 for a quantity of seventy-three systems for the 1st BDE Fielding in September 1999. First unit equipped (FUE) was conducted in September 1998.
Increased funding for Stryker and Future Combat Systems (FCS) came as a result of Army decisions in 2002 to terminate or restructure some 48 systems in the FY ?04-?09 Program Objective Memorandum (POM) long-term spending plan. Among the systems terminated were: United Defense?s Crusader self-propelled howitzer and the A3 upgrade for the Bradley Fighting vehicle, GD?s M1A2 Abrams System Enhancement Program, Lockheed Martin?s Army Tactical Missile System Block II and the associated pre-planned product improvement version of Northrop Grumman?s Brilliant Anti-armor (BAT) munition, Raytheon?s Stinger missile and Improved Target Acquisition System, and Textron?s Wide Area Mine.
The TOW system is used on the HMMWV, the M151 jeep, the armored personnel carrier, the Bradley Fighting Vehicle (BFV) COBRA helicopters, the ITV, and the US Marine Corps light armored vehicle.
Considerable improvements have been made to the missile since 1970. There are six missiles available for the TOW. Three of the five TOW missile versions--Basic TOW, Improved TOW and TOW 2--are no longer being produced for US forces. However, these versions are still used by 40 allied countries.

The TOW anti-tank missile of Iran-Contra fame was introduced for service in the US Army in 1970. Current versions are capable of penetrating more than 30 inches of armor, or "any 1990s tank," at a maximum range of more than 3,000 meters. It can be fired by infantrymen using a tripod, as well from vehicles and helicopters, and can launch 3 missiles in 90 seconds. It is primarily used in antitank warfare, and is a command to line of sight, wire-guided weapon. TOW is used to engage and destroy enemy armored vehicles, primarily tanks. Secondary mission is to destroy other point targets such as non-armored vehicles, crew-served weapons and launchers. This system is designed to attack and defeat tanks and other armored vehicles.

Thousands of missiles and hundreds of launchers were used during Operation Desert Storm. Forces of other countries, including Saudi Arabia, also had TOW at their disposal.
Early reports focused on the problems being experienced by US Army and Marine Corps units in hitting targets during live-fire exercises because soldiers [lacked experience firing the weapon, as well as Iraqi use of "dazzlers" intended to interfere with the guidance of Army TOW missiles and other antitank missiles. But the TOW during ODS was a primary killer of Iraqi tanks, armored personnel carriers,and other vehicles. Before the start of the coalition air campaign in January 1991, Army and Marine Corps planners noted a trend of improvement as more and more units [had] the opportunity to practice firing the TOW. The Iraqi use of dazzlers also proved to be of little concern to coalition commanders. The purpose of the dazzler is to confuse the missile guidance system so it loses track of the missile. It did not work against the TOWs used in Southwest Asia. There were no reports since the war that any of these were effective in any way against TOWs.
Before the start of the actual ground offensive, US Marine units successfully employed the TOW against various Iraqi targets. On 18 January 1991, newspapers reported that U.S. Marine Corps AH-1T Cobra helicopter gunships destroyed an Iraqi command post following Iraq's sporadic shelling of the Khafji area near the Saudi-Kuwaiti border. Four Cobra gunships destroyed a building used as an Iraqi command post with TOW missiles. Accounts told by Gulf War veterans who witnessed the TOW in action during the fighting revealed several instances where TOWs did things that surprised the engineers who designed them more than the soldiers who fired them. TOW missiles proved to be a determining factor in the first ground engagement of Operation Desert Storm. During the Battle of Khafji, which took place before the start of the actual ground offensive, the TOW demonstrated a pretty unique ability. The Saudis fought Iraqi tanks with TOW missiles and drove them out of the city. At one point in the battle, the Saudis saw Iraqi soldiers on top of a water tower. Not wishing to blow up the tower, the Saudis fired a TOW, blew the ladder off the tower and left the Iraqis stranded until the end of the battle." The lethality of the TOW missile was proven beyond doubt during the 100-hour ground campaign when one of the antitank munitions fired by US troops went right through the tank it was aimed at and penetrated another tank parked next to it. Another TOW went through a six foot dirt berm and knocked out an Iraqi armored personnel carrier on the otherside. In both instances, the TOW performed a feat which it supposedly was incapable of accomplishing.
Even without these rather unusual and certainly unexpected displays of its effectiveness, the TOW did better than expected. The system's deadly accuracy proved to be unstoppable even out to its maximum effective range and under degraded visibility conditions. TOW was real powerful hitting because you could tell as soon as it hit, the vehicle was dead. TOW missiles were able to kill targets while the Bradley was on the move.
The basic TOW Weapon System was fielded in 1970. Manufactured by Hughes Aircraft Company, the TOW is the most widely distributed anti-tank guided missile in the world with over 500,000 built and in service in the U.S. and 36 other countries. The TOW has extensive combat experience in Vietnam and the Middle East. Iran may have obtained 1,750 or more TOWs and used TOWs against Iraqi tanks in the 1980s. The TOW 2 launcher is the most recent launcher upgrade. It is compatible with all TOW missiles. The TOW 2 Weapon System is composed of a reusable launcher, a missile guidance set, and sight system. The system can be tripod mounted. However because it is heavy, it is generally employed from the HMMWV. The missile has a 20-year maintenance-free storage life. All versions of the TOW missile can be fired from the current launcher.
The TOW is a crew portable, vehicle-mounted, heavy anitarmor weapon system consisting of a launcher and one of five versions of the TOW missile. It is designed to defeat armored vehicles and other targets such as field fortifications from ranges up to 3,750 meters. After firing the missile, the gunner must keep the cross hairs of the sight centered on the target to ensure a hit. The system will operate in all weather conditions in which the gunner can see a target throughout the missile flight by using either a day or night sight.
The TOW Sight Improvement Program (TSIP) effort began in 199 However, on 15 October 1991 The Secretary of the Army cancelled the TSIP because of declining budget & funding issues. The Assistant Secretary of the Army for Research, Development and Acquisition directed the PEO, Tactical Missiles to coordinate the development of an affordable alternative. The latter effort subsequently became known as the Improved Target Acquisition System (ITAS) being developed for the Army's light forces.
The TOW Improved Target Acquisition System (ITAS) is a materiel change to the The ITAS is a material change to the current TOW2 ground launcher and M966 HMMWV TOW2 acquisition and fire control subsystems for first-to-deploy light forces. ITAS aides in firing all versions of TOW and builds the bridge to TOW F&F. The TOW tripod and launch tube remain unchanged. ITAS significantly increases target acquisition and engagement ranges, while retaining the capability to fire all configurations of the TOW missile. ITAS uses a second-generation forward-looking infrared system, digital components, and an eyesafe laser range finder. ITAS has an improved design with BIT/ BITES for increased maintainability and reduced logistics requirements. It also features an improved man-machine interface that improves system engagement performance. The ITAS modification kit consists of an integrated (Day/ Night Sight with Laser Rangefinder) Target Acquisition Subsystem (TAS), Fire Control Subsystem (FCS), Battery Power Source (BPS), and Modified Traversing Unit (TU). The ITAS will operate from the High Mobility Multi- Purpose Wheeled Vehicle (HMMWV) and the dismount tripod platform. The ITAS will be fielded at battalion level, replacing TOW 2 in light infantry units. The TOW Improved Target Acquisition System low- rate initial production (LRIP) I contract was awarded September 30, 1996, with a production quantity of twenty- five units. LRIP II was awarded March 1998 for a quantity of seventy-three systems for the 1st BDE Fielding in September 1999. First unit equipped (FUE) was conducted in September 1998.
Increased funding for Stryker and Future Combat Systems (FCS) came as a result of Army decisions in 2002 to terminate or restructure some 48 systems in the FY ?04-?09 Program Objective Memorandum (POM) long-term spending plan. Among the systems terminated were: United Defense?s Crusader self-propelled howitzer and the A3 upgrade for the Bradley Fighting vehicle, GD?s M1A2 Abrams System Enhancement Program, Lockheed Martin?s Army Tactical Missile System Block II and the associated pre-planned product improvement version of Northrop Grumman?s Brilliant Anti-armor (BAT) munition, Raytheon?s Stinger missile and Improved Target Acquisition System, and Textron?s Wide Area Mine.
The TOW system is used on the HMMWV, the M151 jeep, the armored personnel carrier, the Bradley Fighting Vehicle (BFV) COBRA helicopters, the ITV, and the US Marine Corps light armored vehicle.
Considerable improvements have been made to the missile since 1970. There are six missiles available for the TOW. Three of the five TOW missile versions--Basic TOW, Improved TOW and TOW 2--are no longer being produced for US forces. However, these versions are still used by 40 allied countries.
In May 1972, US soldiers initially used the TOW in combat during the Vietnam War. This was the very first time that American troops had ever fired an American-made missile under wartime conditions. The system has also seen action in various clashes between Israel and Syria as well as during the Iran/Iraq war. In Saudi Arabia the system was represented by [the HMMWV] with the light forces, the Bradley Fighting Vehicle with the heavy forces, Improved TOW Vehicle with some of the forces, and the Cobra-mounted version.

BGM-71 / M-220 Tube-launc
The TOW anti-tank missile of Iran-Contra fame was introduced for service in the US Army in 1970. Current versions are capable of penetrating more than 30 inches of armor, or "any 1990s tank," at a maximum range of more than 3,000 meters. It can be fired by infantrymen using a tripod, as well from vehicles and helicopters, and can launch 3 missiles in 90 seconds. It is primarily used in antitank warfare, and is a command to line of sight, wire-guided weapon. TOW is used to engage and destroy enemy armored vehicles, primarily tanks. Secondary mission is to destroy other point targets such as non-armored vehicles, crew-served weapons and launchers. This system is designed to attack and defeat tanks and other armored vehicles. The system will operate in all weather conditions and on the "dirty" battlefield.
In May 1972, U.S. soldiers initially used the TOW in combat during the Vietnam War. This was the very first time that American troops had ever fired an American-made missile under wartime conditions.

Torpedoes: Mark 46, Mark
Function: Self-propelled guided projectile that operates underwater and is designed to detonate on contact or in proximity to a target.
Description: Torpedoes may be launched from submarines, surface ships, helicopters and fixed-wing aircraft. They are also used as parts of other weapons; the Mark 46 torpedo becomes the warhead section of the ASROC (Anti-Submarine ROCket) and the Captor mine uses a submerged sensor platform that releases a torpedo when a hostile contact is detected. The three major torpedoes in the Navy inventory are the Mark 48 heavyweight torpedo, the Mark 46 lightweight and the Mark 50 advanced lightweight.
The MK-48 is designed to combat fast, deep-diving nuclear submarines and high performance surface ships. It is carried by all Navy submarines. The improved version, MK-48 ADCAP, is carried by attack submarines, the Ohio class ballistic missile submarines and will be carried by the Seawolf class attack submarines. The MK-48 replaced both the MK-37 and MK-14 torpedoes. The MK-48 has been operational in the U.S. Navy since 1972. MK-48 ADCAP became operational in 1988 and was approved for full production in 1989.
The MK-46 torpedo is designed to attack high performance submarines, and is presently identified as the NATO standard. The MK-46 Mod 5 torpedo is the backbone of the Navy's lightweight ASW torpedo inventory and is expected to remain in service until the year 2015.
The MK-50 is an advanced lightweight torpedo for use against the faster, deeper-diving and more sophisticated submarines. The MK-50 can be launched from all ASW aircraft, and from torpedo tubes aboard surface combatant ships. The MK-50 will eventually replace the MK-46 as the fleet's lightweight torpedo.
MK-48 and MK-48 ADCAP torpedoes can operate with or without wire guidance and use active and/or passive homing. When launched they execute programmed target search, acquisition and attack procedures. Both can conduct multiple reattacks if they miss the target. The MK-46 torpedo is designed to be launched from surface combatant torpedo tubes, ASROC missiles and fixed and rotary wing aircraft. In 1989, a major upgrade program began to enhance the performance of the MK-46 Mod 5 in shallow water. Weapons incorporating these improvements are identified as Mod 5A and Mod 5A(S).

ZU-23 23mm Anti-Aircraft
Function: Lightweight towed anti-aircraft gun.
Background: Introduced in 1964 the ZU-23 was a lightweight air-transportable anti-aircraft gun system. The ZU-23 saw extensive use with airborne and airmobile units, as well as some use in lower readiness motorized rifle units that had not received the mechanized ZSU-23-4 self-propelled air-defense artillery vehicle.
The ZU-23 has an effective range of 2,500 meters vs. air targets, is effective against light armored vehicles and ground targets, and can be fired while limbered.
Description: The ZU-23 weapon system consists of two air-cooled 23mm automatic only cannons mounted on a two wheel transport-firing carriage. While the gun can be fired while limbered for traveling, it is intended to be emplaced wheels up, suspended on its carriage. The carriage contains three built in jacks to level the platform.
