    IABS – RPG Active Countermeasure

    IABS combines an inexpensive radar sensor and airbag systems which are inflated before the RPG hits the protected vehicle. The airbag disrupts the shaped charge fuse, as the projectile collapses upon itself, jamming the time-out fuse, thus defusing the shaped charge before it hits the vehicle’s skin.

    During tests, the system was installed on up-armored Humvees doors, and demonstrated effective protection of the crew compartment. IABS was also effective in protecting the transparent armor (windows) which were broken, but were not penetrated by the RPG.

    ASPS Self Defense System

    Advanced Self Protection System (ASPS), a new generation of self-defense system, developed by Elisra Electronics Systems. The system includes both passive and active subsystems, and incorporates, for the first time of an F-16, both full azimuth coverage RWR and passive (EO) Missile Warning System (MWS). The system can detect pulse, CW, High PRF and Pulse Doppler signals, discriminate them from interference and prioritize the most threatening ones. The system points at a valid threat both visual and audible means. The MWS can also track a threat throughout the engagement. After detecting a missile threat, by its infrared signature, filters the background clutter by a narrow spectral window optimized to real-time signal, by an adaptive threshold. The threat assessment is determined by a after a rapid target algorithm, which tracks each threat frame-by-frame, analyzes target maneuverability, relative position, inertial data and angular velocity and intensity.

    By using infrared imagery and signal processing, PAWS-2 detects and tracks incoming missile’s hot plume as it appears within a protective sphere surrounding the aircraft. The system discriminates between threatening and non-threatening missiles, by evaluating the missile’s trajectories. When it detects a threatening missile, PAWS-2 alerts the aircrew with a warning signal and automatically activates countermeasures such as flares and DIRCM. The ASPS’ active subsystem (jammer) can be used against enemy radars and radar guided threats. The system can employ a rich repertoire of deceptive signals, at various frequencies and power levels, to employ Doppler, range, AM and various noise techniques. The system is also integrated with the Advanced Countermeasures Dispensing System (ACDS) built by BAE Systems’ Israeli based subsidiary (formerly Rokar International). ACDS controls and dispenses various types of countermeasures, including chaff, flares and RF decoys produced by IMI, that adapt to the various phases of the engagement parameters. Special designs allows the ACDS to fire dual chaff cartridges double the number of on-board chaff stores per mission, and fire multi-spectral flares to response or a stronger decoy signal. The EW cockpit displays are provided by the Terma.

    ARENA-E Active Protection System for AFV

    A more complete hemispheric protection is the Russian Arena E – developed by the Russian company KBM. The system is designed to protect the tank from attacks of anti-tank guided missiles launched from the ground and by attack helicopter and lightweight anti-tank grenades (such as RPG). The system weighs between 1 – 1.3 tons (depending on the coverage and configuration) and uses a fixed, omni-directional radar, that covers a sector of 220 – 290 degrees around the tank. The protective charges are housed in a “belt” of 22-26 protective charges (depending on the turret size and shape), each positioned to cover a specific sector. Once an incoming threat is detected by the radar, the system ejects a charge above and sideways from the tank, to a position best suited for intercepting the target. As the charge explodes, it throws a deadly hail of fragments downward, to shutter and destroy the incoming projectile.

    Arena E Active Protection System installed on T-80U

    The system is capable of engaging incoming missiles, at speeds ranging from 70 to 700 meters per second. The system creates a virtual “cone” shaped shield at a radius of 20-30 meters from the tank, and its response time, from target detection to destruction is 0.07 seconds. When the system is triggered, a warning signal is activated, to warn infantrymen that may be following the tank to open some distance or take cover. The status of the Arena E system is unclear, although the system was seen in public since the mid 1990s, it is believed that funding problems delayed final development and deployment of the system.

    While Arena-E provides an effective protection against many types of anti-tank threats, from RPGs to fast missiles such as Hellfire and TOW, it cannot defeat fast missiles (such as HVM) and tank projectiles, such as HEAT shaped charge projectiles and APFSDS penetrators. Different countermeasures are being examined to defeat these threats, including the deployment of steel bars, which are accelerated into the projected flight path of the incoming projectile. The kinetic energy discharged from the collision between the steel bar and the projectile can disintegrate or destabilize the projectile, shift it from its course, or cause it to hit the target at angles that do not facilitate effective penetration.

     

    Aramid Fiber

    Aramid fiber (1961) is a synthetic, fire-resistant polyamide fiber, extensively used in the aerospace and military for structural formations, asbestos substitutes and ballistic protection. Derivatives of the original aramid are Para-aramid fibers, such as Kevlar (also produced as Twaron). Military applications of aramid fibers are in flame resistant clothing, protective vests and helmets, and various composite materials.

    AHEAD Air Burst Munition

    AHEAD technology, developed by Oerlikon Contraves improves the capability of air defense guns such to engage and destroy aerial targets, from large aircraft to small targets such as missiles or PGMs. The gun fires short, 24 round burst of high velocity Ahead rounds aimed at the target’s intercept point. Every projectile is programmed by a muzzle based electromagnetic inductor, which sets an electronic timer to activate and separate the projectile into 152 heavy tungsten metal spin-stabilized sub-projectiles (3.3 gram each), forming a lethal cone shaped metal cloud, placed ahead of the target in its flight path.

    AHEAD is designed to fit existing Skyguard air defense systems, operating twin 35/1000 rpm revolver cannon and Super-fledermaus. The manufacturer claims a very short response time for the system, as low as 4.5 seconds from target detection to firing. With the addition of AHEAD modernization, existing Skyguard fire are fitted with the fire control subsystems which enable the system to be operated as a stand-alone gun or in a “fire unit network”, separated up to three kilometers from each other. The fire units can exchange target search and track data at a fast rate, and share a common, full hemispherical situational picture to facilitate optimal target engagement by each fire unit. AHEAD technology is available today for naval Close-In Weapon Systems, as well as the remote controlled, point defense gun mount and mobile battlefield air defense systems, both are lightweight systems, transportable in a C-130.

    The 30mm AirBurst Munition (ABM) is currently being qualified for the German Army for deployment with the Mk30-2 ABM cannon mounted on the Puma AIFV. A 35mm version optimized for ground-to-ground effect is being qualified for the Bushmaster III chain gun mounted on the new CV9035 IFV of the Royal Dutch Army. Denmark has also selected the ABM capability for its CV9035.

    The ABM concept is also highly suitable as a Counter-Rockets, Mortars and Artillery (C-RAM). During the last year (2005) the Skyshield 35mm systems with ABM munitions were tested in the US and Germany and evaluated against typical C-RAM threats. Further trials are underway. The Israeli Ministry of Defense also evaluated the ABM solution for C-RAM.

    The Power Vest

    A futuristic “power fabrics” is currently in developed by SRI International, in collaboration with Hexcel Schwebel. The team proposes the utilization of multifunctional fabrics, embedded with thin filaments made of lithium ion compounds, shaped into long yarns, wound into high-strength polymer fibers. Such fabrics will provide both electrical power for a soldier’s equipment and protection against projectile impact. Such fabrics will reduce and distribute the weight of batteries that now must be carried separately.

    TDA 2R2M Rifled 120mm Mortar System

    A joint development by the US- Picatinny Arsenal and Thomson Daimler-Benz Aerospace (TDA) has created the Dragon Fire, an autonomous mortar system. The current prototype consists of a modified TDA 2R2M rifled 120mm mortar, with a maximum range unassisted/rocket-assisted of nine and 14kms respectively. It can be operated remotely by radio and can calculate (GPS) within three to five seconds its own location and elevation and bearing to the target. An on-board magazine holds 33 rounds ready to fire, and the package can be towed by a HMMWV tactical vehicle or fit inside a V-22 Osprey. A derivative, dubbed Mobile Dragon Fire, has been mounted on a USMC light armoured vehicle (LAV), and the addition of a gyro stabiliser should result in accurate fire on the move out to maximum ranges.

    A second prototype, the Armoured Mortar vehicle, with a semi-automatic 120mm recoiling rifled mounted mortar, 2R2M, with an optional smooth bore version, was designed and developed by FNSS in cooperation with the Deutsche Aerospace.

(four hours over the current maximum life). The new lightweight cell will retain AEA’s Li-ion capabilities but will sustain operation environment at -40C to +70C degrees range. Typical application are soldier modernization programs such as the Land Warrior and the FIST programs in the US and the UK respectively.

    Spike Multi-Purpose Anti-Armor Missile

    Manufacturer: RAFAEL / Eurospike

    Spike is a new generation, electro-optical, medium to long range anti-tank missile developed at the RAFAEL Missile Division Anti-Armor Directorate. Spike can defeat advanced Main Battle Tanks (MBT) as well as secondary targets such as buildings and soft-skin vehicles. The system is based on a common system architecture providing medium, long and extended long range precision attack capability for infantry, mobile, airborne and sea-based applications. The Spike family members include:

    The weapon consists of the missile in its canister and the firing post comprising a command launch unit, thermal imager and firing post. Command and launch unit, imaging infrared/CCD seekers, and part of the missile electronics are common to all family members. The powerful tandem warhead, rocket motor and flight control mechanisms also utilized similar elements, to reduce production cost.

    Spike’s high probability of kill (Pk) of both stationary and moving targets, is achieved by a sophisticated tracking algorithms and simple but effective guidance controls. Spike can be employed in two trajectories – in the lofted trajectory mode, the missile climbs high above the ground and then dives onto the target. Utilizing the low trajectory, the missile flies close to ground level and makes a direct attack on the target. This type of attack is useful especially at close range and in urban terrain. The weapon’s lofted trajectory is more suitable for attack of armoured vehicles, which are more vulnerable to top attack. From this position, the target is clearly visible at the terminal attack phase, and the operator can aim the missile to hit at the most vulnerable points. The basic operating mode for the Spike is a “fire and forget”. After firing, the missile automatically guides itself to the target impact. However, utilizing the fiber-optic communications link, Spike missile can also get target and guidance updates during the flight. This capability also enables the gunner to observe the target throughout the whole flight, as seen through the missile seeker. He can control the aim point during flight, thus ensuring the target is hit at its most vulnerable spot, which may not have been visible from the firing position. The fibre-optic data link also provides man-in-the-loop control all the way to target impact, hence permitting Spike to be used in operations which are subject to tough Rules of Engagement.

    Rafael offers a complete Integrated Logistics Support package including training. The gunners’ training program utilizes the Spike gunnery simulator, covers all skills necessary to operate the weapon at full combat efficiency, thus minimizing the need for training firings and.

    Spike is currently operational with the armies of: Israel, Singapore, Netherlands and Finland. The missile was selected as the future anti-tank missile for Poland, and is currently competing for the replacement of Milan with the British Army.

    RAMTECH

    RAMTECH is composed of Ceramic modules, encased in energy absorbing rubber molds, are also utilized in the RAMTECH armor. This material can be used as appliqué armor, for land and amphibious vehicles, as it offers both environmental durability and exceptional multi-hit performance, against 12.7, 14.5 and up to 30mm protection levels.

    Energy Harvesting Programs for Military Use

    The development of longer life, lighter and thinner batteries is some of the challenges facing battery manufacturers in programs such as the Land Warrior system. The battery should be paratrooper qualified, weigh below two pounds and up to 1.6 inches (4 cm) thick. The battery should power all the systems electronics, for 8-10 hours missions, including computers, communications devices and vision enhancement devices. Some innovative ideas are currently being tested for Land Warrior type applications, such as integrating rechargeable cells into the clothing of the soldier or into ammunition belts. This requires flat cells such as those used in Lithium-ion polymer rechargeable batteries. For the near term, The Army considers advanced, rechargeable and primary batteries. For the longer term, the Army is studying a one-pound rechargeable battery belt, 1.5 pound fuel cells, and 1.5 pound methanol canisters.

    Further into the future, micro fuel cell solutions are considered. The fuel cell is an energy-generating device that creates power through the chemical reaction of a fuel in the presence of a catalyst. Recent results have shown that liquid hydrocarbon fuels can be converted directly into electricity in a solid oxide fuel cell. Considerable challenges are still to be tackled, primarily thermal integration, signature reduction, etc. The introduction of new materials is one of the solutions for the challenges. Porous super-thermal conductors and advanced aerogel materials are being considered for heat transfer and isolation in advanced fuel cells. Battery Intelligence’ is developing fuzzy logic methodology to monitor the state of health of power cells. Such systems could be based on impedance and other output parameters. With a carefully characterized fuel cell, it is possible to detect changes in humidity in fuel supply gas and correct it before permanent damage occurs to the fuel cell. As before, the software is code efficient and the additional logic circuitry is minimal

    2S31 Vena Self Propelled Howitzer/Mortar

    AMOS II mobile mortar system.

    In 1996 the Russian Motovilikha Plants Corporation fielded the latest of its Nona family, the 2S31 Vena, an automated self propelled mortar, with a longer barrel, (Russian 120mm 2A80) also firing the Gran laser-guided bomb against point targets to 13km range.

    The known version was mounted on a BMP-3 chassis and has 70 rounds on board storage ( about twice as much as the former). A similar version was developed by the Chinese Army, designated WZ 551 6×6 mounted on an armoured personnel carrier. Finally, as the Russians seem to love super-big guns, they have designed the mammoth 420mm SP Oka mortar system, which was originally intended to fire tactical nuclear rounds. Fortunately it was never commissioned.

    Conformal Fuel Tanks for Advanced F-16 Block 50/52/60

    Block 52/60 F-16 aircraft, currently procured for Israel, Greece and the UAE, have structural, plumbing, and wiring provisions for the Conformal Fuel Tanks (CFT). These external, pod-like fuel reservoirs are attached on the upper surface of the F-16’s fuselage, with the tank’s lower surface conforming to the aircraft shape. The upper surface arrangement allows the CFTs to be relatively light weight because nothing is suspended from them. With an empty weight of 900 pounds, tank set holds 450 gallons (ca. 3,050 pounds, or 2,271 litres) of additional JP-5/8 fuel.

    The extra fuel increases range, loiter time, and combat persistence as well as reduces the demand for tanker support. Range increase is on the order of twenty to forty percent, depending on the stores configuration and mission profile. The tanks have neglible effect on the aircraft agility, at subsonic speed, However, at supersonic speed, the drag is increased proportionally to the increase in speed. When fitted with CFT the aircraft retains almost the full handling qualities, flight limits, and signature. A complete set can be removed or replaced within two hours. The CFTs are built to Lockheed Martin’s specification, by IAI as a sole source, as part of the Peace Marble V program offsets.

    “The CFTs have very little adverse effect on the F-16’s renowned performance,” said Maj. Timothy S. McDonald, U.S. Air Force project pilot for CFT testing at Eglin. “A set of CFTs carries 50 percent more fuel than the centerline external fuel tank, but has only 12 percent of the drag.” The CFTs are designed for the full F-16 flight envelope – up to 9 g’s, maximum angle of attack and sideslip and maximum roll rate.

    Israel, for example placed a special significance to the operational flexibility of its new F-16I, derived from the added range and endurance provided by the CFT. For medium range air-to-surface missions, CFTs can eliminate the need for wing tanks. This allows doubling the F-16’s primary weapon capacity and flying with two, rather than one, types of large weapons in a balanced configuration. In long range missions, the use of CFT dramatically increases the operational radius of the aircraft, since it enables the aircraft to fly a long range strike mission, with full weapon’s load, and engage in air combat when external (370 Gal) fuel tanks are dropped. When external 370 gal jetissonable tanks or 600gal non-jetissonable external tanks are added the F-16 can demonstrate up to 60-70 percent increase in operational radius. Another Israeli development utilizes a new fuel carrying configuration for the F-16, which enables the carrying of up to four 370 gallon external tanks, plus one 300 gallon under the belly, resulting in 25% increase in mission radius and twice the endurance on patrol missions.
