KC-135 Stratotanker
Function: The KC-135 Stratotanker's principal mission is air refueling. This asset greatly enhances the U. S. Air Force's capability to accomplish its mission of Global Engagement. It also provides aerial refueling support to U.S. Navy, U.S. Marine Corps and allied aircraft.
History: AMC manages more than 442 Stratotankers (primary aircraft assigned), of which the Air Force Reserve and Air National Guard fly 268 of those in support of AMC's mission. McConnell Air Force Base, Kan., is the host for the first KC-135 Air Force Reserve associate unit, the 931st Air Refueling Group, which shares KC-135s with the base's 22nd Air Refueling Wing. The Boeing Company's model 367-80 was the basic design for the commercial 707 passenger plane as well as the KC-135A Stratotanker. In 1954 the Air Force purchased the first 29 of its future fleet. The first aircraft flew in August 1956 and the initial production Stratotanker was delivered to Castle Air Force Base, CA, in June 1957. The last KC-135 was delivered to the Air Force in 1965.
Of the original KC-135A's, almost 400 have been modified with new CFM-56 engines produced by CFM-International. The re-engined tanker, designated either the KC-135R or KC-135T, can offload 50 percent more fuel, is 25 percent more fuel efficient, costs 25 percent less to operate and is 96 percent quieter than the KC-135A.
Under another modification program, Air Force Reserve and Air National Guard tankers were re-engined with the TF-33-PW-102 engines. The re-engined tanker, designated the KC-135E, is 14 percent more fuel efficient than the KC-135A and can offload 20 percent more fuel.
Through the years, the KC-135 has been altered to do other jobs ranging from flying command post missions to reconnaissance. The EC-135C is U.S. Strategic Command's flying command post. One EC-135C is on alert at all times, ready to take to the air and control bombers and missiles if ground control is lost. Special reconnaissance uses RC-135s and NKC-135A's are flown in test programs for Air Force Systems Command. Air Combat Command operates the OC-135 as an observation platform in compliance with the Open Skies Treaty.
With projected modifications, the KC-135 will fly and refuel into the next century. A new aluminum-alloy skin grafted to the underside of the wings will add 27,000 flying hours to the aircraft.
Over the next few years, the aircraft will undergo a number of upgrades to expand its capabilities and improve its reliability. Among these are wingtip, air refueling pods; improved cockpit instrument displays; additional communication equipment and enhanced navigation aids.
Description: Four turbofans, mounted under 35-degree swept wings, power the KC-135 to takeoffs at gross weights up to 322,500 pounds (146,285 kilograms). Nearly all internal fuel can be pumped through the tanker's flying boom, the KC-135's primary fuel transfer method. A special shuttlecock-shaped drogue, attached to and trailed behind the flying boom, may be used to refuel aircraft fitted with probes. An operator stationed in the rear of the plane controls the boom. A cargo deck above the refueling system can hold a mixed load of passengers and cargo. Depending on fuel storage configuration, the KC-135 can carry up to 83,000 pounds (37,648 kilograms) of cargo.

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.

.50 Caliber Cartridge
Description: There are currently eleven .50 caliber cartridges in service.
M2/M33 .50 Caliber ball cartridge: The M2 is the original standard .50 caliber ball cartridge. The M33 is a redesigned, modern version of the M2, and is identical in all respects. The M2/M33 can be identified by its unpainted (copper) tip.
M1/M10/M17 .50 Caliber tracer cartridge: The M1/M10/M17 are tracer variants of the M2/M33 cartridge. They are essentially identical to one another in terms of ballistic performance and function. These M1 has a red painted tip, the M10 has a orange tip, and the M17 has a brown tip.
M1 .50 Caliber incendiary cartridge: The M1 incendiary cartridge is an incendiary cartridge primarily intended for use against aircraft and material. The M1 can be identified by its blue tip.
M23 .50 Caliber incendiary cartridge: The M23 incendiary cartridge is similar to the M1 incendiary cartridge and is used in the same capacity as the M1. The M23 cartridge has a blue tip with a light blue ring below it.
M2 .50 Caliber armor piercing cartridge: The M2 armor piercing cartridge was designed for use against soft skinned and lightly armored vehicles as well as for use against enemy built up defensive positions. It has no incendiary component. The M2 can be identified by its black tip.
M8 .50 Caliber armor piercing / incendiary cartridge: The M8 armor piercing / incendiary cartridge was designed for use against soft skinned and lightly armored vehicles as well as material destruction. It has an incendiary component. The M8 can be identified by its silver (aluminum) tip.
M20 .50 Caliber armor piercing / incendiary tracer cartridge: The M20 armor piercing / incendiary tracer cartridge is the tracer variant of the M8 API cartridge. The M20 can be identified by its red tip with a silver (aluminum) ring below that.
M1A1 .50 Caliber blank firing cartridge: Designed for use with training simulators, the M1A1 has no projectile and contains a reduced powder charge. The M1A1 can be identified by its crimped and sealed cartridge opening in place of a projectile.
History: Soon after American servicemen deployed to Europe for World War One, it was recognized that an automatic weapon capable of firing a cartridge larger than those currently in service was sorely needed. In addition to being more powerful than the standard rifle cartridge, this new cartridge would also need an armor penetrating capability to serve as a against the recently introduced tank. Although America was not able to produce such a weapon before the end of the war, research and experimentation with a number of captured German anti-tank firearms eventually lead to the Browning M1921A1 .50 caliber machine gun. Introduced in 1922, the Browning M1921A1 machine gun fired a massive .50 caliber cartridge and had an effective range of over 1000 meters. The M1921A1 was later modified to improve barrel life and reliability, and was redesignated the M2HB (heavy barrel) machine gun in 1933. The M2HB is still in service with the U.S. military where it is used in a number of roles, ranging from infantry heavy machine gun to vehicle, helicopter, and small boat and craft armament.

AN/GAU-8 30mm Cannon
Description: The AN/GAU-8 Avenger 30mm gun system was specifically built to serve as a Close Air Support "Tank Buster." Similar to the earlier M61 20mm Vulcan design, the Avenger uses seven barrels to achieve a rate of fire of 3,900 rounds per minute. The Avenger fires a mix of 30mm electrically primed PGU-13/B High Explosive Incendiary (HEI) rounds and PGU-14/B Armor Piercing Incendiary (API) rounds. While the HEI rounds provide the Avenger the ability to destroy light skinned vehicles, the weapon's real punch is delivered by the API rounds, each of which incorporates over half a pound of super-dense Depleted Uranium (DU.) At 1,200 meters (4,000 feet) a 2 second burst from the AN/GAU-8 will deliver 100 rounds containing 65 pounds of DU and place 80 percent of these projectiles within 20 feet of the target.
The AN/GAU-8 is used exclusively by the United States Air Force A-10 Thunderbolt II, a dedicated Close Air Support aircraft which was essentially designed around the Avenger gun system.
Background: Soon after the end of the Second World War the newly formed United States Air Force identified a need for an improved gun system for its aircraft. While adequate as an air combat / ground attack weapon during World War Two, the Browning M2 .50 caliber machine gun had been rendered obsolete by jet aircraft and needed to be replaced by a weapon with increased range, rate of fire, and projectile lethality. Realizing that singled barreled automatic weapons had essentially reached their design limits, the U.S. Army Ordnance Research and Development Service hit on the idea of re-introducing the multi-barreled rotary weapon invented by Richard J. Gatling in the 1880s. Initial tests proved promising as a vintage Gatling gun, now powered by an electric motor in place of the usual hand crank, was able to achieve rates of fire in excess of 4,000 rounds per minute.
In 1946 the General Electric company received the contract for this new program, code named "Project Vulcan," and was tasked with producing functional prototypes in a number of calibers for further testing. In 1952 GE produced three different guns; .60 caliber, 20mm, and 27mm. After extensive testing, the 20mm version was selected for further testing to determine its suitability as an aircraft mounted weapon. In 1956 the gun was standardized as the M61 20mm cannon and entered service with both the United States Army and Air Force.

M40/42 Protective Mask
Function: Provide respiratory, eye and face protection against chemical and biological agents, radioactive fallout particles, and battlefield contaminants.
Entered Army Service: 1992.
Description: The M40-series protective masks replace the M17-series protective mask as the standard Army field mask, providing improved comfort, fit and protection. The mask consists of a silicone rubber face piece with an in-turned peripheral face seal, binocular rigid eye lens system and elastic head harness. Other features include front and side voicemitters allowing better communication particularly when operating FM communications, drink tube for a drinking capability while being worn, clear and tinted inserts, and a filter canister with NATO standard threads. Because of these features, the mask can be worn continuously for 8 to 12 hours.
The face-mounted canister (gas and aerosol filter) can be worn on either the left or the right cheek, and will withstand a maximum of 15 nerve, choking, and blister agent attacks. It will also withstand a maximum of two blood agent attacks. Biological agents do not degrade the filter.
The M40A1 is the mask issued to dismounted soldiers. It is available in small, medium, and large sizes.
The M42A2 Combat Vehicle Crewman Mask has the same components as the M40A1 with an additional built-in microphone for wire communication. The filter canister is attached to the end of the hose with an adapter for the CPFU connection.
The M45 Protective Mask, issued to Blackhawk crew members, provides protection without the aid of forced ventilation air. It is compatible with aircraft sighting systems and night vision devices. It has close fitting eyepieces, a voicemitter, drink tube, and a low profile filter canister.
The M48 and M49 masks, issued to Apache aviators, are an upgrade of the M43 Type I mask. Their improved blower is chest-mounted, lighter, less bulky, and battery powered.
Several mask improvements have been introduced over the years through Pre-Planned Product Improvement (P3I) Programs, which resulted in M40A1 and M40A2 configurations. The improvements include a quick-doff hood, second skin, canister interoperability (M42A1 only), and voice amplification (M7), new nosecup, two new carriers, and improved vision correction. An additional product improvement was adopted in late 1994, which upgraded the M42 to the M42A2 configuration. This change provides a detachable microphone that improves reliability, simplifies production, and permits field replacements.
