U-2R/U-2S
Function: The U-2 provides continuous day or night, high-altitude, all-weather, stand-off surveillance of an area in direct support of U.S. and allied ground and air forces. It provides critical intelligence to decision makers through all phases of conflict, including peacetime indications and warnings, crises, low-intensity conflict and large-scale hostilities.
History: Current models are derived from the original version that made its first flight in August 1955. On Oct. 14, 1962, it was the U-2 that photographed the Soviet military installing offensive missiles in Cuba.
The U-2R, first flown in 1967, is significantly larger and more capable than the original aircraft. A tactical reconnaissance version, the TR-1A, first flew in August 1981 and was delivered to the Air Force the next month. Designed for stand-off tactical reconnaissance in Europe, the TR-1 was structurally identical to the U-2R. Operational TR-1A's were used by the 17th Reconnaissance Wing, Royal Air Force Station Alconbury, England, starting in February 1983. The last U-2 and TR-1 aircraft were delivered to the Air Force in October 1989. In 1992 all TR-1s and U-2s were redesignated U-2R. Current U-2R models are being reengined and will be designated as a U-2S/ST. The Air Force accepted the first U-2S in October, 1994.
When requested, the U-2 also has provided photographs to the Federal Emergency Management Agency in support of disaster relief.
U-2s are based at Beale Air Force Base, CA and support national and tactical requirements from four operational detachments located throughout the world. U-2R/U-2S crew members are trained at Beale using three U-2ST aircraft. The last R model trainer will be converted to an S model trainer in 1999.
Description: The U-2 is a single-seat, single-engine, high-altitude, reconnaissance aircraft. Long, wide, straight wings give the U-2 glider-like characteristics. It can carry a variety of sensors and cameras, is an extremely reliable reconnaissance aircraft, and enjoys a high mission completion rate.
Because of its high altitude mission, the pilot must wear a full pressure suit. The U-2 is capable of collecting multi-sensor photo, electro-optic, infrared and radar imagery, as well as performing other types of reconnaissance functions. However, the aircraft can be a difficult aircraft to fly due to its unusual landing characteristics.
The aircraft is being upgraded with a lighter engine (General Electric F-118-101) that burns less fuel, cuts weight and increases power. The entire fleet should be reengined by 1998. Other upgrades are to the sensors and adding the Global Positioning System that will superimpose geo-coordinates directly on collected images.

RAH-66 Comanche
Function: Fire support and security for forward and rear area forces, point target/anti-armor, anti-helicopter, armed escort, supporting arms control and coordination, point and limited area air defense from enemy fixed-wing aircraft, armed and visual reconnaissance.
Description: The Boeing-Sikorsky RAH-66 Comanche is the Army's next generation armed reconnaissance helicopter. It also is the first helicopter developed specifically for this role. The Comanche will provide Army Aviation the opportunity to move into the 21st century with a weapon system of unsurpassed warfighting capabilities crucial to the Army's future strategic vision. The Comanche is intended to replace the current fleet of AH-1 and OH-58 helicopters in all air cavalry troops and light division attack helicopter battalions, and supplement the AH-64 Apache in heavy division/corps attack helicopter battalions.
The first Boeing-Sikorsky RAH-66 Comanche prototype was rolled-out at Sikorsky Aircraft, Stratford, Connecticut, May 25, 1995. The prototype's first flight was made on 04 January 1996. The second prototype is scheduled to fly in late March 1999. Six early operational capability aircraft are scheduled to be delivered 2002 to participate in an Army field exercise in 2002-2003, or possibly later in "Corps 04." The Comanche is powered by two Light Helicopter Turbine Engine Co. (LHTEC) T800-801 engines. These advanced engines and a streamlined airframe will be enable the Comanche to fly significantly faster than the larger AH-64 Apache.
The RAH-66 Comanche helicopter's primary role will be to seek out enemy forces and designate targets for the AH-64 Apache Attack helicopter at night, in adverse weather, and in battlefield obscurants, using advanced infrared sensors. The helmet has FLIR images and overlaid symbology that can be used as a headup display in nape-of-the-earth (NOE) flight.
The aircraft has been designed to emit a low-radar signature (stealth features). The Comanche will perform the attack mission itself for the Army's light divisions. The RAH-66 will be used as a scout and attack helicopter to include an air-to-ground and air-to-air combat capability. The Comanche is slated to replace the AH-1 Series Cobra light attack helicopter, the OH-6A Cayuse, and the OH-58A/OH-58C Kiowa light observation helicopters.
The Comanche mission equipment package consists of a turret-mounted cannon, night-vision pilotage system, helmet-mounted display, electro-optical target acquisition and designation system, aided target recognition, and integrated communication/navigation/identification avionics system. Targeting includes a second generation forward-looking infrared (FLIR) sensor, a low-light-level television, a laser range finder and designator, and the Apache Longbow millimeter wave radar system. Digital sensors, computers and software will enable the aircraft to track and recognize advesarys long before they are aware of the Comanche's presence, a key advantage in both the reconnaissance and attack roles.
Aided target detection and classification software will automatically scan the battlefield, identifying and prioritizing targets. The target acquisition and communications system will allow burst transmissions of data to other aircraft and command and control systems. Digital communications links will enable the crew unparalleled situational awareness, making the Comanche an integral component of the digital battlefield. The armament subsystems consist of the XM301 20mm cannon, and up to 14 Hellfire anti-tank missiles, 28 Air-to-Air Stinger (ATAS) anti-aircraft missiles, or 56 2.75 inch Hydra 70 air-to-ground rockets carried internally and externally. Up to four Hellfire and two Air-to-Air Stinger (ATAS) missiles can be stowed in fully-retractable weapons bays and the gun can be rotated to a stowed position when not in use. This design feature reduces both drag and radar signature.
Mission management, status, and control information is provided over the MIL-STD-1553B databus between the mission equipment packages and the Turreted Gun System. The Comanche will have enhanced maintainability through it's modular electronics architecture and built-in diagnostics.
Features:
Sensors and avionics. In the reconnaissance role, the Comanche will be equipped with a new generation of passive sensors and a fully integrated suite of displays and communications. Advance infrared (IR) sensors will have twice the range of OH-58D Kiowa Warrior and AH-64 Apache sensors. The Comanche will be equipped with the Apache Longbow fire control radar and the Helmet Integrated Display and Sight System (HIDSS). The fully integrated avionics system will allow tactical data to be overlaid onto a digital map, allowing the crew to devote more time for target detection and classification. A triple-redundant fly-by-wire system can automatically hold the helicopter in hover or in almost any other maneuver, reducing workload, allowing the pilot to concentrate on navigation and threat avoidance. A hand-on grip permits one-handed operation.
Stealth characteristics. The Comanche incorporates more low-observable stealth features than any aircraft in Army history. The Comanche radar cross-section (RCS) is less than that of a Hellfire missile. To reduce radar cross-section, weapons can be carried internally, the gun can be rotated aft and stowed within a fairing behind the turret when not in use, and the landing gear are fully-retractable. The all-composite fuselage sides are flat and canted and rounded surfaces are avoided by use of faceted turret and engine covers. The Comanche's head-on RCS is 360 times smaller than the AH-64 Apache, 250 times less than the smaller OH-58D Kiowa Warrior, and 32 times smaller than the OH-58D's mast-mounted sight. This means the Comanche will be able to approach five times closer to an enemy radar than an Apache, or four times closer than an OH-58D, without being detected.
Noise suppression. The Comanche only radiates one-half the rotor noise of current helicopters. Noise is reduced by use of a five-bladed rotor, pioneered by the successful Boeing (McDonnell Douglas) MD-500 Defender series of light utility helicopters. The fantail eliminates interaction between main rotor and tail rotor wakes. The advanced rotor design permits operation at low speed, allowing the Comanche to sneak 40% closer to a target than an Apache, without being detected by an acoustical system.
Infrared (IR) suppression. The Comanche only radiates 25% of the engine heat of current helicopters, a critical survivability design concern in a low-flying tactical scout helicopter. The Comanche is the first helicopter in which the infrared (IR) suppression system is integrated into the airframe. This innovative Sikorsky design feature provides IR suppressors that are built into the tail-boom, providing ample length for complete and efficient mixing of engine exhaust and cooling air flowing through inlets above the tail. The mixed exhaust is discharged through slots built into an inverted shelf on the sides of the tail-boom. The gases are cooled so thoroughly that a heat-seeking missile cannot find and lock-on to the Comanche.
Crew Protection. The Comanche features a crew compartment sealed for protection against chemical or biological threats, an airframe resilient against ballistic damage, enhanced crash-worthiness, and reduced susceptibility to electromagnetic interference.
Maintainability. Comanche will be easily sustained, will require fewer personnel and support equipment, and will provide a decisive battlefield capability in day, night and adverse weather operations. Comanche has been designed to be exceptionally maintainable and easily transportable. Through its keel-beam construction, numerous access panels, easily accessible line-replaceable units/modules and advanced diagnostics, the RAH-66 possesses "designed-in" maintainability. Comanche aircraft will be able to be rapidly loaded into or unloaded from any Air Force transport aircraft.

RQ-1 Predator Medium Alti
Function: Medium altitude endurance unmanned aerial vehicle.
History: Unmanned Aerial Vehicles (UAVs) are either remotely or autonomous pilotless drones typically used for reconnaissance. UAVs can trace their roots back to the AQM-34N Firebee. Derived from the Ryan Aeronautical Company Firebee sub-sonic target drone, the AQM-34N had a range of more than 2,400 miles, could fly above 65,000 feet, and had a top speed of 420 miles per hour. During the Vietnam war the Firebee recon drones were made more maneuverable and equipped with electronic countermeasures and jamming equipment to defend them from surface to air missiles and air interception.
UAVs are generally equipped with a payload bay which can house a variety of sensor packages, allowing mission planners to tailor the UAV's sensors for a specific mission requirement.
UAVs are generally divided into two categories: Tactical and Endurance. Tactical UAVs typically have a range of at least 200km while Endurance UAVs have a range beyond 200km.
Background: The RQ-1 Predator Medium Altitude Endurance (MAE) UAV was introduced in May 1995 as a proof of concept demonstrator. The RQ-1A/B Predator is a system, not just an aircraft. The fully operational system consists of four air vehicles (with sensors), a ground control station (GCS), a Predator primary satellite link communication suite and 55 people.
The Predator air vehicle and sensors are commanded and controlled by its GCS via a C-band line-of-sight data link or a Ku-band satellite data link for beyond-line-of-sight operations. During flight operations the crew in the GCS is an air vehicle operator and three sensor operators. The aircraft is equipped with a color nose camera (generally used by the air vehicle operator for flight control), a day variable aperture TV camera, a variable aperture infrared camera (for low light/night) and a synthetic aperture radar for looking through smoke, clouds or haze. The cameras produce full motion video and the synthetic aperture radar produces still frame radar images. On the RQ-1B, either the daylight variable aperture or the infrared electro-optical sensor may be operated simultaneously with the synthetic aperture radar.
Since introduction, the Predator has performed over 600 missions in support of peacekeeping operations in Bosnia. The Predator was deployed to Kosovo in 1999 as part of the air war. During this deployment the Predator performed intelligence gathering, target acquisition and tracking, and battlefield coordination.
Based on lessons learned in the Kosovo air war, where the lapse of time between target acquisition and the arrival of aircraft to destroy the target was so great that many targets were able to evade destruction, the Predator was armed with AGM-114 Hellfire laser guided missiles. In a February 2001 test, a Hellfire armed Predator successfully engaged and destroyed a target tank at Indian Springs auxiliary airfield in Nevada.
In October 2001 Hellfire capable Predators were deployed to Afghanistan to perform intelligence gathering, target acquisition, tracking, and, when armed, attack missions.
Description: The Predator air vehicle is a single wing, single engine platform. The fuselage is slender, except for the bulbous nose which houses most of the vehicles sensors. The single wing is centrally mounted low on the body and is of a high aspect ratio design. The motor is a Rotax 912 four-cylinder engine, which runs on 100-octane gasoline, produces 81 horsepower and is mounted in the tail section of the aircraft in a pusher configuration. The two rear "tailerons" are mounted in an inverted configuration on the fuselage just forward of the engine.

GBU-24 Paveway III
Description: The GBU-24 Paveway III represents the next step beyond the GBU-10 series of Laser Guided Bomb. Reacting to increased air defense lethality, which force attack aircraft to penetrate the target area in a nap of the earth (NOE) profile, as well as provide a low level LGB option in the event of poor battlefield visibility or low ceiling, the GBU-24 was specifically designed for low altitude deliveries. Utilizing the same principles as the GBU-10, the GBU-24 uses either the Mk. 84 2,000 pound bomb or the BLU-109 penetration bomb with an improved seeker head optimized for low-level release. To increase standoff range and improve low level glide characteristics, the GBU-24 is equipped with significantly larger guidance fins. As with the Paveway I and II, targets may be designated by either the launching aircraft or another aircraft in the area, by an Unmanned Aerial Vehicle (UAV), or by personnel on the ground. In addition, since the GBU-24 orients itself on the reflected laser, rather than the target, it can be directed towards a different target after launch simply by pointing the designator at a different target.
The Guided Bomb Unit-24 (GBU-24) Low Level Laser Guided Bomb [LLLGB] consists of either a 2,000-pound MK-84 general purpose or BLU-109 penetrator bomb modified with a Paveway III low-level laser-guided bomb kit to add the proportional guidance in place of the bang-bang type used in the Paveway II. The LLLGB was developed in response to Sophisticated enemy air defenses, poor visibility, and to counter limitations in low ceilings. The weapon is designed for low altitude delivery and with a capability for improved standoff ranges to reduce exposure. The GBU-24 LLLGB/Paveway III has low-level, standoff capability of more than 10 nautical miles. Performance envelopes for all modes of delivery are improved because the larger wings of the GBU-24 increases maneuverability. Paveway III also has increased seeker sensitivity and a larger field of regard.
The operator illuminates a target with a laser designator and then the munition guides to a spot of laser energy reflected from the target. One way to deliver LGBs from low altitude is a loft attack. In this maneuver, the aircraft pulls up sharply at a predetermined point some miles from the target and the LGB is lofted upward and toward the target. However, if the LGB guidance system detects reflected laser energy from the target designator too soon after release, it tends to pull the LGW down below its required trajectory and the bomb will impact well short of the target.
This bomb is not nearly as delivery parameter sensitive as is the Paveway II LGB, nor is it affected by early laser designation. After a proper low altitude delivery, the LLLGB will maintain level flight while looking for reflected laser energy. If it does not detect reflected laser energy, it will maintain level flight to continue beyond the designated target, overflying friendly positions, to impact long, rather than short of the target.
Unlike the Paveway II LGB, the LLLGB can correct for relatively large deviations from planned release parameters in the primary delivery mode (low-altitude level delivery). It also has a larger delivery envelope for the dive, glide and loft modes than does the earlier LGB. The wide field of view and midcourse guidance modes programmed in the LLLGB allow for a "Point Shoot" delivery capability. This capability allows the pilot to attack the target by pointing the aircraft at the target and releasing the weapon after obtaining appropriate sight indications. The primary advantage of this capability is that accurate dive/tracking is not required to solve wind drift problems.
The Multi-Segment Hard Target Penetrator (MSHTP) concept has been designed to use the penetration capability of a BLU-113 or BLU-109 linked to the void counting hard target smart fuse. This weapon detonates a copper cutter charge upon entering the target and cuts the rear portion of the bomb off, which then detonates. The rest of the weapon continues down to the next level.
BLU-116 Advanced Unitary Penetrator [AUP] GBU-24 C/B (USAF) / GBU-24 D/B (Navy)
Air Force Research Laboratory Munitions Directorate engineers have completed development of a new warhead known as the Advanced Unitary Penetrator, or AUP. The warhead was successfully transitioned to the Precision Strike System Program Office at Eglin AFB, Fla. for Engineering Manufacturing Development (EMD) and production. The AUP was developed in less than three years at a cost of less than $8M. AFRL's emphasis on operational suitability as part of AUP weapon design will allow the EMD program to be completed in less than half the time of a normal EMD program.
The Advanced Unitary Penetrator [AUP] hard target penetrator features an elongated narrow diameter case made of a tough nickel-cobalt steel alloy called Air Force 1410. With the official designation of BLU-116, and designated the GBU-24 C/B (USAF) and GBU-24 D/B (Navy), is designed to provide at least twice the penetration capability of existing BLU-109 2000-pound bombs. The AUP is being demonstrated with Boeing as prime and Lockheed-Martin as subcontractor. Penetration capability is directly proportional to the warhead's sectional density--its weight divided by its cross section. The AUP maximizes sectional density by reducing the explosive payload and using heavy metals in the warhead case. Lower explosive payload will diminish dispersion of NBC agents to help reduce collateral effects. The AUP will retain the carriage and flight characteristics of the BLU-109, and it will be compatible with the GBU-24, GBU-27, and GBU-15/AGM-130 series of precision-guided bombs. Thus, the AUP will be capable of delivery from a wider inventory of aircraft, including stealth platforms, than the BLU-113/GBU-28. A proposal to replace the current CALCM warhead with an AUP warhead provides 2.5 times BLU-109 penetration capability.
The AUP development effort was conducted in support of the Counterproliferation Initiative (CPI) Advanced Concept Technology Demonstration (ACTD). The program objective was to develop and demonstrate a weapon that could be rapidly transitioned for Air Force and Navy use against hardened targets associated with the production, storage, and weaponization of chemical or biological agents. Normally, the introduction of a new weapon is a very long, expensive, and tedious process - as long as ten years or more. The associated cost may be tens of millions of dollars.
The 1700-pound AUP warhead is tucked inside a lightweight aerodynamic shroud. This "outer skin" gives the AUP the exact physical and aerodynamic characteristics of the BLU-109. The shroud strips away from the internal penetrator when the weapon impacts the target. Compared to the BLU-109, the AUP has thicker case walls, a tougher case material, an improved nose shape, and a smaller explosive charge. The cross-sectional area of the AUP penetrator, however, is only half as great as the cross-sectional area of the BLU-109. A smaller explosive charge reduces collateral damage potential by reducing blast overpressure that could expel chemical or biological agents from the target. A long testing series demonstrated AUP's compatibility with the Munitions Directorate-developed Hard Target Smart Fuze (HTSF). The HTSF allows the AUP to be detonated at the optimal point within a target to inflict maximum damage. That ability compensates for the reduction in explosive charge.
Because it is a "twin" to the BLU-109, the AUP can utilize a proven system of hardbacks, guidance units, and tail fin kits. The costs associated with developing new kits is eliminated. The operational users - pilots, weapon handlers and load crews - will gain the improved war fighting capabilities of the AUP without the costs associated with retraining support personnel or the acquisition of new delivery systems and support equipment. Battle commanders will also have increased ability to neutralize deeply buried hardened targets.
GBU-24E/B
GBU-24E/B, an Enhanced Paveway Laser Guided Bomb, is a precision-guided hardened target penetrator used to destroy hardened aircraft hangers and underground bunkers. It integrates a Global Positioning System and a ring laser gyro inertial measuring unit (IMU) to the already fielded GBU-24B/B "Paveway III" with the existing laser guidance. A new guidance and control unit has been modified to incorporate GPS electronics, GPS antenna, IMU and software for precision GPS/INS guidance. Testing of this system began in late 1999.
Background: Precision-guided munitions (PGM) can trace their origins back to World War Two. These early weapons, such as the QB-17G "Aphrodite" were essentially airframes packed with explosives and guided via radio direction signals to their target, where they would crash and explode. While guidance was extremely crude by today's standards, these weapons were more accurate than conventional dropped munitions, and did not expose aircrews to deadly enemy anti-aircraft fire. Unfortunately, such weapons were unwieldy, unsuitable for small targets, and were themselves subject to defensive fire. The first truly precision-guided munitions did not appear until the Vietnam War. Serving as a major supply conduit for North Vietnam, the mile long Paul Doumer Bridge over the Red River was the most important ground target of the war. Unfortunately, it was also one of the most heavily defended, its approaches ringed with anti-aircraft guns and surface to air missile emplacements. While American pilots were able to attack the bridge using conventional munitions, such missions were extremely hazardous and casualties were high. In 1967 the Rockwell International Corporation was tasked with producing a precision munition using electro-optical guidance technology. The end result was the GBU (Guided Bomb Unit) 8 or Homing Bomb System (HOBOS), a conventional Mk. 84 2,000 pound bomb with a TV like electro-optical guidance package in the nose to provide direction and a modified tail fin assembly in the rear to provide lift. To launch the GBU-8 the pilot aligned the TV camera sight in the bomb with the target and the weapons officer locked the bomb's seeker onto the target. Once aligned, the bomb could be released well away from the target area and it would guide itself into the target with a high degree of accuracy.

Joint Direct Attack Munit
Description: The Joint Direct Attack Munition (JDAM) GBU-31 is a tailkit under development to meet both USAF and Navy needs, with the Air Force as the lead service. The program will produce a weapon with high accuracy, all-weather, autonomous, conventional bombing capability. JDAM will upgrade the existing inventory of general purpose and penetrator unitary bombs, and a product improvement may add a terminal seeker to improve accuracy. JDAM can be launched from approximately 15 miles from the target and each is independently targeted.
JDAM is not intended to replace any existing weapon system; rather, it is to provide accurate delivery of general purpose bombs in adverse weather conditions. The JDAM will upgrade the existing inventory of Mk-83 1,000- and Mk-84 2,000-pound general purpose unitary bombs and the 2,000-pound hard target penetrator bomb by integrating a guidance kit consisting of an inertial navigation system/global positioning system guidance kit. The 1,000-pound variant of JDAM is designated the GBU-31, and the 2,000-pound version of the JDAM is designated the GBU-32. JDAM variants for the Mk-80 250-pound and Mk-81 500-pound bombs are designated GBU-29 and GBU-30, respectively. Hard Target penetrators being changed into low-cost JDAMs included the 2,000 pound BLU-109 and 1,000 pound BLU-110.
The JDAM will be continuously updated by aircraft avionics systems prior to release. Once released, the bomb's INS/GPS will take over and guide the bomb to its target regardless of weather. Guidance is accomplished via the tight coupling of an accurate GPS with a 3-axis INS. The Guidance Control Unit provides accurate guidance in both GPS-aided INS modes of operation and INS-only modes of operation. This inherent JDAM capability will counter the threat from near-term technological advances in GPS jamming. The weapon system allows launch from very low to very high altitude and can be launched in a dive, toss, loft or in straight and level flight with an on-axis or off-axis delivery. JDAM also allows multiple target engagements on a single pass delivery. JDAM provides the user with a variety of targeting schemes, such as preplanned and inflight captive carriage retargeting.
Potential Upgrades
The JDAM product improvement program may add a terminal seeker for precision guidance and other system improvements to existing JDAMs to provide the Air Force with 3-meter precision and improved anti-jamming capability. The Air Force is evaluating several alternatives and estimates that the seeker could be available for operations by 2004. The seeker kit could be used by both the 2,000-pound blast fragmentation and penetrator JDAMs.
The Advanced Unitary Penetrator (AUP), a candidate to be integrated with a GBU-31 guidance kit, is a 2000 lb. class penetrator warhead intended as an upgrade/replacement for the BLU-109 warhead in applications requiring increased penetration. The AUP is designed to provide increased penetration capability over the BLU-109 warhead while maintaining the same overall weight, mass properties, dimensions, and physical interfaces associated with the BLU-109 warhead. This concept integrates the AUP warhead with the GBU-31, the JDAM tail kit for 2,000 lb class warheads. This concept uses the Hard Target Smart Fuze (HTSF), an accelerometer based electronic fuze which allows control of the detonation point by layer counting, distance or time. The accelerometer senses G loads on the bomb due to deceleration as it penetrates through to the target. The fuze can distinguish between earth, concrete, rock and air.
The boosted penetrator concept is based on achieving maximum penetration without sacrificing operational flexibility. Total system weight will be less than 2,250 pounds so that it can be carried by all AF tactical aircraft and bombers as well as the Navy?s F/A-18. The goal is to achieve greater penetration than the GBU-28 with a near term, affordable design. A dense metal warhead will be used with a wraparound rocket motor to allow internal carriage in the F-117. Advanced explosives will be used to compensate for the reduced charge weight. This concept integrates the boosted penetrator warhead with a JDAM guidance kit with an adverse weather Synthetic Aperture Radar (SAR).
The Ballasted Penetrator in GBU-32 concept is a 1000 pound dense or ballasted penetrator integrated with a GBU-32 guidance kit using compressed carriage for internal carriage in advanced fighters (F-22, JSF) or carriage in cruise missiles (JASSM, CALCM, ACM, ATACMS, Tomahawk.) The warhead would either be designed with a dense metal case or contain dense metal ballast for maximum penetration. The warhead will be filled with an advanced insensitive explosive to compensate for the reduced charge weight. The warhead will be integrated with the GBU-32, the JDAM tail kit for 1,000 lb class warheads.
The Boosted Unitary Penetrator concept is based on achieving maximum penetration in a weapon that will fit internally in the F-22. Total system weight will be less than 1300 pounds. A dense metal warhead will be used with a wraparound rocket motor. Use of next generation compressed seekers and aero-control designs along with reaction jet control will allow the size to shrink sufficiently to fit inside F-22 and JSF. Advanced explosives will be used to compensate for the reduced charge weight. This concept integrates the boosted penetrator warhead with a JDAM guidance kit with an adverse weather Synthetic Aperture Radar (SAR).
The JDAM/BLU-113 concept improves the GBU-28 by enhancing the nose design of the BLU-113 warhead for improved penetration. The warhead nose reshape will improve BLU-113 penetration by more than 25%. The penetration could potentially be further improved by replacing the traditional HE fill with a dense explosive. The design involves integrating the improved BLU-113 warhead with a JDAM tail kit.
The Compressed Carriage GBU-32, J1K, enhanced fill concept is a JAST-1000 warhead with enhanced fill integrated with a GBU-32 guidance kit using compressed carriage for internal carriage in advanced fighters (F-22, JSF) or carriage in cruise missiles (JASSM, CALCM, ACM, ATACMS, Tomahawk.) The warhead is a combined penetrator and blast/fray warhead. The warhead shape is optimized for penetration and the enhanced fill and internal liner provide blast and controlled fragmentation capability. The warhead is shrouded to match the MK-83 mass properties and interfaces. The warhead will be integrated with the GBU-32, the JDAM tail kit for 1,000 lb class warheads. Use of aero-control designs along with reaction jet control will allow the size to shrink sufficiently to fit inside F-22 and JSF. This concept uses the Hard Target Smart Fuze (HTSF).
The Direct Attack Munitions Affordable Seeker (DAMASK) Fleet Advanced Demonstration (FAD) accuracy enhancement kit is a seeker of the lowest possible cost that will improve JDAM accuracy to three-meter circular error probability (CEP). The three-year FAD began in FY 98 and continued through FY 00. DAMASK includes a very low-cost sensor mounted to the front of a JDAM and an off-the-shelf signal processor mounted in the existing JDAM tail kit. It uses an uncooled imaging-infrared focal plane array (UIIFPA) sensor and low-cost optics, both developed for the consumer automobile market. An off-the-shelf, commercially available signal processor is the final component of the accuracy upgrade kit, estimated to cost less than $12.7 thousand per seeker in quantity. During the final stages of weapon flight, DAMASK's unique guidance system will image the target area, locate a mission-planned aimpoint and update the JDAM target location. The mission-planning image can come from satellite, uninhabited air vehicles or reconnaissance aircraft. A template is then automatically produced from the mission-planning image and loaded on board the aircraft with the baseline JDAM mission plan. Organic targeting is possible because the target area can be imaged with onboard synthetic aperture radar (SAR) or forward looking infrared (FLIR) sensors, and the pilot can then select the desired impact point using a heads-down display.
History: JDAM is being developed by Lockheed Martin and Boeing [McDonald Douglas]. In October 1995, the Air Force awarded a contract for EMD and for the first 4,635 JDAM kits at an average unit cost of $18,000, less than half the original $40,000 estimate. As a result of JDAM's pilot program status, low-rate initial production was accelerated nine months, to the latter half of FY 1997. On April 30, 1997, the Air Force announced the decision to initiate low-rate initial production (LRIP) of JDAM, with the first production lot of 937 JDAM kits. The JDAM Integrated Product Team achieved a phenomenal 53 guided JDAM weapon releases in the six months prior to the LRIP decision. JDAM demonstrated high reliability and outstanding accuracy. Twenty-two of the weapon releases were accomplished during an early Air Force operational assessment. Over a four-week period operational crews put JDAM through an operationally representative evaluation, including targets shrouded by clouds and obscured by snow. All 22 weapons successfully performed up to their operational requirements including overall accuracy of 10.3 meters, significantly better than the 13 meter requirement. Early operational capability JDAMs have been delivered to Whiteman Air Force Base, MO, and low-rate, initial production JDAM deliveries begin on 02 May 1998. McDonnell Douglas Corporation of Berkeley, MO, was awarded on 02 April 1999, a $50,521,788 face value increase to a firm-fixed-price contract to provide for low rate initial production of 2,527 Joint Direct Attack Munition (JDAM) kits. The work is expected to be completed by January 2001.
The JDAM program is nearing the end of its development phase. More than 250 flight tests involved five Air Force and Navy aircraft. JDAM will be carried on virtually all Air Force fighters and bombers, including the B-1, B-2, B-52, F-15E, F-16, F-22, F-117, and F/A-18.
JDAM was certified as operational capable on the B-2 in July 1997. Limited Initial Operational Capability was achieved on the B-52 in December 1998.
