An-124 Condor
Function: High payload, long range cargo aircraft.
History: Introduced in 1982 as a long range, heavy lift cargo and troop transport aircraft, the Antonov An-124 Ruslan (NATO designation Condor) is currently the world's largest and heaviest payload aircraft in production in the world. Outclassing the C-5 Galaxy by nearly 20 tons in payload capacity, and the Ilyushin Il-76 by more than 100 tons, the An-124 is only exceeded in lifting ability by the special purpose An-225 Mriya (NATO designation Cossack) which was purpose built to transport the Russian space shuttle, and of which only two were built.
Currently in production at the AVIASTAR facility in Ulyanovsk and the AVIANT State Aviation Plant in Kiev, the An-124, in addition to serving with the Russian military as a long range high payload cargo aircraft capable of delivering or airdropping troops, and equipment, is also in service with a number of civilian organizations as a dedicated cargo transport. Antonov Airlines, Volga-Dniepr, and Poliot all employ the An-124, using it to transport heavy and over sized equipment such as hydraulic turbines, mobile cranes, railway locomotives, earthmovers and dump trucks, and sailing vessels. The An-124 is even capable of transporting other aircraft, ferrying partially disassembled passenger planes to customers worldwide.
To facilitate the loading and unloading of cargo, the nose section is hinged to open upwards, and the tail section is fitted with a pair of clamshell doors. Both nose and tail sections are equipped with integral loading ramps. In addition, the An-124 also employs two traveling cranes, two winches, a rollgang and tie down equipment which limit it's dependence on ground equipment for cargo handling and manipulation. The Ruslan is equipped with multi leg, self-orienting landing gear and is rough surface capable. The landing gear height can be adjusted on the ground, to facilitate loading cargo.
In addition to the An-124-100 currently in production, Air Foyle (UK) in conjunction with Antonov and Aviastar has proposed the construction of two new versions, the An-124-210, and the An-124-100M. Both versions will be equipped with Western and Russian digital instruments and displays which will reduce the crew size from 6 to 4. In addition, both will be equipped with a traffic alert collision and avoidance system, ground proximity warning system and a satellite communications system. The 210 will be outfitted with Rolls-Royce RB211-52H-T engines, while the 100M will be equipped with the Series 3 D-18 engines, produced by the Progress Design Bureau in Zaporozhe. Each of these engine upgrades will increase the Ruslan's range by 10% and reduce take off distance.
Description: Typical of most cargo aircraft, the An-124 body forms a thick oval cross-section, with a tapered aft section and rounded nose to facilitate cargo handling. The fuselage is of a twin deck design, the upper deck being the flight deck, and the lower deck serving as the cargo hold. On the flight deck are the cockpit, with stations for the six crewmembers, a relief crew compartment, and seating for an additional 88 passengers. The loadmaster's station is on the cargo deck.
The wings are mounted high on the fuselage at a negative dihedral, are tapered and swept, with a relatively high cross-section to increase efficiency and range. The four Lotarev D-18T turbofans are mounted on pylons underneath the wings. The horizontal stabilizers are also swept back and tapered, and are mounted at mid level on the fuselage, aft of the vertical stabilizer.

Il-76 Candid
Function: Medium range, medium lift cargo aircraft.
History: The Ilyushin Il-76 (NATO designation Candid) was fielded by the Soviet Air Force in 1974 as a medium range, medium payload, rough surface capable cargo aircraft. Produced by the Ilyushin Aviation Complex Joint Stock Company in Moscow and the Tashkent Aircraft Production Corporation in Tashkent, Uzbekistan, the Il-76 was purpose built as a combat support aircraft who's primary mission was to deliver infantry and light armored vehicles. The Il-76 is also paratrooper capable, and can air deliver palletized cargo and specially prepared military vehicles.
To facilitate rough field operations, the Il-76 is equipped with a low ground pressure landing gear system and extendable trailing flaps and leading edge slats on the wings to generate additional lift at low airspeeds. To support airborne cargo delivery missions, the Candid is equipped with a telpher; an over-head electrically operated track from which cargo can be suspended and deployed, as well as a deck mounted roller conveyer system. The Il-76 can also be converted to a litter capable airborne ambulance.
Since its introduction, the Il-76 has undergone a number of modifications. The Il-76M is virtually identical to the base line Il-76 in terms of physical appearance, and flight characteristics, but with almost twice the payload capacity (47 tons for the M model, up considerably from the 28 tons of the basic model.) The Il-76MD is essentially an Il-76M with structural modifications to increase fuel load and range. The additional fuel carried increased the MD's maximum take off weight by 20 tons, and increased the range of the aircraft by 40%. The Il-76MF variant incorporates a 6.6-meter insertion into the fuselage to increase cargo hold dimensions, as well as improved engines, replacing the four D-30KP turbofan engines with four more powerful PS-90A-76 turbofans. These new engines improve range by 20% over the MD model. The MF's maximum take off weight has been increased to 210 tons, and the maximum payload has been increased to 52 tons.
In addition to serving as a cargo aircraft, the basic Il-76 design has been modified to fill a number of additional aircraft requirements. The A-50 Mainstay Airborne Early Warning radar aircraft is derived from the Il-76 design, and the Il-78 Midas aerial tanker is derived from a modified MD airframe.
Description: As with most cargo aircraft, the Il-76 body was designed to maximize available space. The fuselage is long and more rounded in cross-section than the more contemporary An-124 Condor, with a tapered aft section and rounded nose. The tail has a pair of clamshell doors and integral loading ramp for cargo. The nose, un-like the C-5 Galaxy or the An-124 Condor, is fixed, and the lower section is glassed in for observation. Directly behind the glass nose section is an oval radome, which extends laterally beyond the sides of the frame.
The wings are mounted high on the fuselage at a slight negative dihedral, and are tapered and swept. The four turbofans are mounted on pylons underneath, and forward of the wings. The horizontal stabilizers are also swept back and tapered, and are mounted high on the vertical stabilizer.
Designed as a combat aircraft, the Il-76 is capable of mounting an electronic warfare ECM package, to include radar warning receiver, and chaff and flare dispensers, to defend the aircraft from radar guided and heat seeking missile threats, and is capable of mounting air dropped ordnance on external, wing mounted ejector racks. In addition, the tail section incorporates a manned weapons station, mounting two 23mm cannons and a fire direction radar. This tail gun station is retained on many Russian owned, civilian operated Il-76s, as they were expected to serve with the Air Force during a time of war.

BM-21 122mm Rocket Launch
Function: 122mm self propelled rocket launcher.
Background: The BM-21 Grad (Hail) rocket launcher is the world's most widely-used rocket launcher system. Introduced to the Red Army in 1963 as a replacement for the BM-14 140mm rocket launcher, the BM-21's rockets carry the same sized warhead as the 140mm, and have a much longer range. In addition, because the rockets are smaller in diameter, more rockets can be carried per launcher.
The BM-21 can be operated and fired from the cab, or it can be fired from up to 60 meters away remotely. All 40 rockets can be fired in 6 seconds or they can be fired singly or in groups at 0.5 second intervals. Reloading the launcher takes less than 8 minutes.
The BM-21 fires a 122mm diameter rocket out to a range of 20,380 meters. Although the rockets are primarily fin stabilized, each launch tube is rifled to improve the accuracy of the rocket. In addition to HE-fragmentation, chemical, and incendiary warheads, the BM-21 is also capable of firing extended range munitions out to 36,000 meters.
The BM-21 is currently in service with over 50 countries worldwide, and is manufactured in Russia, North Korea, Egypt, China and Czechoslovakia.
Description: The BM-21 is a 40 round multiple launch rocket system mounted on the rear of a Ural-375D 6?6 cargo truck chassis. The rockets are stacked in 4 banks of 10 rockets apiece. Unlike other rocket launchers, there is no blast shielding around the cab of the transport vehicle.

Landing Craft, Air Cushio
Function: Heavy lift, high speed, over the horizon air cushion landing craft.
Description: The Landing Craft, Air Cushion (LCAC), is a heavy lift, high speed landing craft which floats on a layer of air. Where conventional landing craft have a maximum speed of 8 knots and had to move to within two miles before loading and landing troops ashore, the LCAC can load and assault from 50 miles out and deliver its payload at 35 knots or more. In addition, where conventional landing craft are limited to less than 17% of the world's beach area, the LCAC can ignore the effects of tides, ocean depth, sand bars and underwater obstacles, ice, marshes, wetlands, and can clear above ground obstacles up to 4 feet high, giving it access to over 80% of the world's beaches. Lastly, where conventional landing craft are of limited value in transporting troops and equipment in other than assault conditions, the LCAC is capable of delivering payloads far inland, using existing road networks or accessible terrain, to prevent the dangerous buildup of equipment and supplies on the beach, or rapidly shuttling troops and equipment up and down the beach to meet critical tactical needs. The LCAC achieves its performance by floating four feet above the ground or ocean. Where conventional landing craft and surface effect ships have at least some portion of their hull in the water, the LCAC hovers above it. The air cushion is formed by a flexible, rubberized canvas skirt which surrounds the bottom of the LCAC and filled by four centrifugal fans driven by two of the craft's Avco-Lycoming gas turbine engines, each of which generates 12,280 brake horsepower. Each LCAC is capable of transporting up to 60 tons of payload (75 tons in approved overload situations) or up to 180 combat soldiers, and has front and rear loading ramps fro rapid transfer of cargo. The LCAC is compatible with all existing Amphibious Warfare transports and carriers, and can be driven directly into the loading area (forgoing the need for a lengthy recovery operation) for rapid reloading and combat turn around.

XM8
The XM8 Future Combat Rifle is intended to replace existing M4 Carbines and select 5.56mm x45 weapons in the US Army arsenal beginning as early as the fourth quarter of FY05.
In October 2002 ATK (Alliant Techsystems) was awarded a $5 million contract modification from the U.S. Army Armament Research, Development, and Engineering Center (ARDEC), Picatinny, N.J., to develop the new XM8 Lightweight Assault Rifle. ATK Integrated Defense, Plymouth, Minn., and teammate Heckler and Koch, Oberndorf, Germany, will support the rapid development program, which will investigate the potential of the XM8 as the lightweight assault rifle for the Army's Objective Force.
The XM8 will be based on the kinetic energy weapon that is part of the XM29 next-generation infantry weapon system (formerly the Objective Individual Combat Weapon) currently under development by ATK Integrated Defense. The kinetic energy weapon, which fires 5.56mm ammunition, will provide maximum commonality in components and logistics with the XM29 system.
The XM8 will provide lethality performance comparable to the currently fielded M4 carbine rifle, while weighing 20 percent less than the M4 because of advanced technologies developed for the XM29 program.
The XM8 Lightweight Assault Rifle will reduce the 21st century soldier's load and increase his mobility - two very important aims of the Army's Objective Force Warrior and Land Warrior initiatives. The progress made to reduce weight and improve performance on the XM29 program is key to the decision on accelerating the development of the XM8, which is integrated with the Army's efforts to transform to a more lethal and rapidly deployed fighting force as part of its Objective Force.
ATK Integrated Defense is the system integrator on the XM29 program. Teammates on the program are Heckler and Koch, weapon development; ATK Ammunition Systems, Arden Hills, Minn., ammunition development; Brashear LP, Pittsburgh, Pa., integrated full solution fire control; and Omega, Columbus, Ga., training systems.
The XM8 is a true family of weapons with different barrel lengths designed to address all the needs of an infantry squad. The standard model is expected to be lighter than the M4 carbine and no larger in size. There?s also a sharpshooter version for increased range; a compact version for cramped quarters; and an auto-rifle version for a squad-automatic weapon. The XM8 family has a 9-inch compact, 12.5-inch carbine and a 20-inch sharpshooter and automatic rifle. The 12.5-inch carbine is 6.4 pounds with an objective of 5.7 pounds and is 33 inches with its adjustable stock extended. The M-16 A2 is 39.63 inches long and 8.79 pounds with a 30-round magazine.
Internally, the XM8 uses a rotary locking bolt system that functions and fieldstrips like those used in the M-16 rifle and M-4 carbine, according to the XM8 manufacturer?s ? Heckler & Koch ? Website. The bolt is powered by a unique gas operating system with a user-removable gas piston and pusher rod to operate the mechanism. Unlike the current M-4 and M-16 direct gas system with gas tube, the XM8 gas system does not introduce propellant gases and carbon back into the weapon?s receiver during firing.
While the XM8 was not exposed to battlefield conditions, it?s still a feat the current service rifle hasn?t come close to rivaling, said Rich Audette, deputy project manager for PM Soldier Weapons. During their Oct. 20-23 2003 trip to Germany, the weapons experts said they were impressed after watching Heckler & Koch engineers fire four high-capacity magazines, with 100 rounds a piece, in less than five minutes.
This improved reliability can be credited to differences in the XM8?s operating system from the one in the M16. For instance, a thin gas tube runs almost the entire length of the barrel in all of the M16 variants. When the weapon is fired, the gases travel back down the tube into the chamber and push the bolt back to eject the shell casing and chamber a new round. The XM8?s gas system instead is connected to a mechanical operating rod, which pushes back the bolt to eject the casing and chamber the new round each time the weapon is fired. So there?s no carbon residue constantly being blown back into the chamber, reducing the need to clean the weapon as often. You don?t get gases blowing back into the chamber that have contaminates in them. The XM8 also has a much tighter seal between the bolt and the ejection port, which should cut down on the amount of debris that can blow into the weapon when the ejection port?s dust cover is open.
The XM8 is part of the Army?s effort to perfect an over-and-under style weapon, known as the XM29, developed by Alliant Techsystems and H&K. It fires special air-bursting projectiles and standard 5.56mm ammunition. But the XM29 still is too heavy and unwieldy for Army requirements. Instead of scrapping the XM29, the Army decided to perfect each of XM29?s components separately, so soldiers can take advantage of new technology sooner. The parts would be brought back together when lighter materials become available. The XM8 is one of those components.
From December 2003 through late May 2004, soldiers got a chance to fire the prototypes in desert, tropical and arctic environments. A limited-user test then was conducted, possibly at Fort Campbell, Ky., where soldiers test the prototypes for about three weeks while training in offensive and defensive scenarios. Improvements will be made based on soldier and test feedback before the final three-months of operational tests, which are scheduled to begin in fall 2004. The final decision will be up to the Army?s senior leadership, but weapons officials said they were confident the XM8 weapon system will be adopted. If all goes well, the XM8 could be ready for fielding by late summer 2005.
Beginning life as the 5.56mm KE (kinetic energy) component of the 20mm air-bursting XM29 Objective Individual Combat Weapon (OICW), the XM8 Lightweight Modular Carbine System represents the state-of-the-art in 5.56x45mm NATO assault rifles. Developed by the US Army?s office of Project Manager for Soldier Weapons located at Picatinny Arsenal, New Jersey in close conjunction with the US Army Infantry Center, the XM8 Future Combat Rifle is intended to replace existing M4 Carbines and select 5.56mm x45 weapons in the US Army arsenal beginning as early as the fourth quarter of FY05. Once adopted, the M8 Carbine will replace the aging M16/M4 family of weapons, which have been in service for nearly four decades, longer than any previous US service rifle. The M8 Carbine will be up to 20% lighter than a comparably equipped M4 Carbine MWS and yet offer additional features and performance unavailable currently in any assault rifle in the world.
As a direct development of the separable OICW (XM29) KE or Kinetic Energy module, the M8 Carbine will share a high degree of common parts and training and maintenance procedures to lessen the required support for the ?family? of XM8 weapons. Being developed are four XM8 variants, which include a baseline carbine, a sharpshooter variant, an automatic rifle variant, and the ultra-compact carbine variant. A unique feature of the XM8 modular weapon system is the ability to easily and quickly reconfigure the weapon from one variant to the other to meet changing mission requirements, to include caliber conversion.
This modularity includes the exchange of interchangeable assembly groups such as the barrel, handguard, lower receiver, buttstock modules and sighting system with removable carrying handle. In addition and in parallel, the new XM320 quick detachable single-shot 40mm grenade launcher with side-opening breech and LSS lightweight 12 gauge shotgun module can be easily added to the XM8 by the user in the field without tools. The unique buttstock system allows the operator exchange buttstocks without tools from the standard collapsible multi-position version, to an optional buttcap for maximum portability or an optional folding or sniper buttstock with adjustable cheekpiece for special applications. Internally the XM8 employs a combat-proven robust rotary locking bolt system that functions and fieldstrips like that used in the current M16 rifle and M4 carbine. However this bolt is powered by a unique gas operating system that employs a user removable gas piston and pusher rod to operate the mechanism. Unlike the current M4/M16 direct gas system with gas tube, the XM8 gas system does not introduce propellant gases and the associated carbon fouling back into the weapon?s receiver during firing. This greatly increases the reliability of the XM8 while at same time reducing operator cleaning time by as much as 70%. This system also allows the weapon to fire more than 15,000 rounds without lubrication or cleaning in even the worst operational environments. A cold hammer forged barrel will guarantee a minimum of 20,000 rounds service life and ultimate operator safety in the event of an obstructed bore occurrence.
The XM8 has fully ambidextrous operating controls to include a centrally located charging handle that doubles as an ambidextrous forward assist when required, ambidextrous magazine release, bolt catch, safety/selector lever with semi and full automatic modes of fire and release lever for the multiple position collapsible buttstock. The operating controls allow the operator to keep the firing hand on the pistol grip and the weapon in the firing position at all times while the non-firing hand actuates the charging handle and magazine during loading and clearing. Major components of the weapon are produced from high-strength fiber reinforced polymer materials that can be molded in almost any color to include OD green, desert tan, arctic white, urban blue, brown and basic black. Surfaces on the XM8 that interface with the operator are fitted with non-slip materials to increase comfort and operator retention. The XM8 uses 10 or 30-round semi-transparent box magazines and high-reliability 100-round drum magazines for sustained fire applications.
Special integral flush mounted attachment points are located on the handguard and receiver to allow the quick attachment of targeting devices. Unlike MIL-STD-1913 rails, the XM8 attachment points do not add additional weight, bulk and cost to the host weapon, and will accept MIL-STD-1913 adapters to allow for the use of current in-service accessories. The attachment points for the standard multi-function integrated red-dot sight allow multiple mounting positions and insure 100% zero retention even after the sight is removed and remounted. The battery powered XM8 sight includes the latest technology in a red dot close combat optic, IR laser aimer and laser illuminator with back-up etched reticle with capability exceeding that of the current M68-CCO, AN/PEQ-2 and AN/PAQ-4. This sight will be factory zeroed on the weapon when it is delivered and does not require constant rezeroing in the field like current rail-mounted targeting devices. The XM8 will be fully compatible with future Land Warrior technology and components.
The US XM8 Carbine is being designed at the HK Defense design center in Sterling, Virginia and will be produced and assembled in the United States at the new Heckler & Koch manufacturing plant located in Columbus, Georgia, adjacent to Fort Benning. The unit cost of the XM8 will be less than that of the current M4 Carbine and will guarantee the American war fighter uncompromising performance far exceeding that of current in-service M4 Carbines.
