Dec 23, 2004

The Garl Gustaf Weapon System is a multi-role man portable “artillery” providing infantry units the ability to engage any type of target, including armor, building, bunkers, personnel etc. The system enables deployment of smoke and illumination charges. The M3 system relies on a 84mm reloadable, recoilless launcher and a family of munitions including the HEAT 751 which uses a tandem warhead to defeat over 500mm of steel including reactive armor (ERA). The rocket is designed to pass through bushes or scrub without activating the precursor charge, thus enabling firing from ambush.

When ERA penetration is not required, the HEAT 551 variant can be used, offering extended range of up to 700 meters. For combat in urban terrain, M3 can be loaded with HEDP 502 dual purpose rocket which can defeat light armor, concrete, bunkers or brick walls. The HE 441 charge was designed specifically for engagement of soft targets. Unlike the other rockets, it is equipped with an impact or delay fuse, to enable air-burst effect. The warhead has 800 steel pellets enclosing the high explosive charge.

A different load – ADM 401 can be used for close-in protection of ambush teams armed with the M3. This rocket carries a payload of 1,100 flechettes and has an effective range of 100 meters.

The flechettes are released and accelerated by gas pressure in a cone, resulting in distribution of 5 – 10 flechettes per square meter at a distance of 100 meters. Smoke, illumination and training rounds complete this impressive weapon system.

The AT4 CS / CS HP was designed especially for urban combat – the anti-armor weapon (CS HP) uses an 84mm fin-stabilized rocket, armed with high penetration shaped charge which provides armor penetration capability exceeding 500mm of steel equipped with special internal ballistics allowing it to be fired from confined spaces such as tight jungle, in front of an obstacle or with own troops in close vicinity. The weapon has a high hit probability up to 300 meters. The weapon is carried in a dispensable canister/launcher weighing 7.8kg (the AT4 HEAT version which is not designed for use in a confined space weighs 6.7 kg and, has higher muzzle speed but lower armor penetration > 420mm).

Dec 11, 2004

A new seekerless precision strike weapon system developed by Lockheed Martin, could revolutionize next-generation strike weapons. This all-weather, precision standoff seekerless 1,000 lb weapon uses an inexpensive wing set to provide maneuvering G’s and energy to interdict evasive targets. Target cuing is received via datalink from other sensors, resulting in a near-zero navigation Circular Error Probability (CEP). The weapon uses low-cost, two-way data link to receive continuous corrections to the current GPS system, providing a direct hit without the use of an end-game seeker. The datalink provides weapon tracking and status. PNAV is expected to be a key ingredient in future Small Diameter Bomb (SDB) applications, as it enables reduction of CEP well below the 4meter requirement without a costly seeker.

GPS Anti-Jam Receiver (AJR)

The Anti-jam GPS Receiver (AGR) designed by Raytheon supports the Tactical Tomahawk missile program. The system uses PPS (Y-code) GPS signals, operating on both the L1 and L2 frequencies. When configured with a multi-element Controlled Reception Pattern Antenna (CRPA), the AGR’s post-correlation nulling techniques allow continued satellite track in the presence of high levels of hostile jamming. This patented anti-jam concept also provides satellite beam steering, to further enhance the tracking thresholds, and to mitigate the “spurious nulls” that can degrade the performance of other nulling implementations (e.g., pre-correlation). The AGR sequentially tracks up to eight visible satellites, and provides high-quality pseudorange/delta pseudorange (PR/DPR) measurements corrected for the effects of selective availability. The Tactical Tomahawk’s navigation processor then uses the PR/DR measurements to yield a high-performance navigation solution.

Natural body heat creates a distinctive signature inherent to human body, therefore, Infantrymen appear conspicuously hot on thermal image. Personal camouflage should significantly reduce heat signature reduction in addition to visual camouflage provided by the color scheme. The German company TEXPLORER has developed Ghost – a metallized fabric creating such an effect. The washable, reusable fabric can be adapted to all types of countryside and temperature ranges with various background printed patterns.

Precision Targeting System

Radar (active) guidance technology prevailed in anti-ship and surface attack weapons during the 1980s. This guidance technique was recently adapted to land attack missiles. After the missile flies to a pre-designated location where line of sight to the target is expected, it activates its radar in a scan mode, and will home in on the signal expected to be the target. Such signal can be the strongest in the area, or one that emits a characteristic signature. Radar guided missiles are highly vulnerable to countermeasures and deception, which sometime necessitate human intervention for target verification and intervention at terminal phase. When used over land, radar seekers can be augmented by other elements (such as EO, GPS, LADAR etc).

Other applications of much smaller radar guidance use millimeter wave radars, to locate, classify, identify and engage armored vehicles and other priority targets. The use of millimeter wave seekers provides very high resolution, all weather capability and high immunity to current conventional countermeasure techniques employed by armored vehicles.

Due to their cost and operating and design complexities, GPS/AJ receivers will not be deployed everywhere, but only in specific applications. To protect those systems which are not immune to jamming or interference, high power non space-based GPS transmitters called pseudo-satellites, or pseudolites could satisfy the demanding needs for anti-jam GPS navigation aids. The Pseudolite transmitter is conceptually simple, consisting of a GPS Anti-Jam reference receiver, integrated with an Inertial Measurement Unit (IMU) for position reporting, a GPS RF signal generator, an atomic frequency standard and supporting equipment such as power amplifier, power supply and datalink receiver. Rockwell Collins already demonstrated the feasibility of Pseudolites under a DARPA program. During tests, an airborne Pseudolite was deployed on US Army Hunter UAVs, emplaced as a secondary payload on the Hunter’s boom pods. In addition to its navigation support, Pseudolite can also provide ad-hoc datalink communications, supporting smart munitions with retargeting information, flexible fusing and other advanced features. Pseudolites can provide significant anti-jam GPS flexibility when deployed over a localized or wide area, without any change to existing hardware.

Bonus artillery launched, fire-and-forget artillery shell targets and destroys armored vehicles (stationary or mobile) by top attack submunitions. Each BONUS shell carries two BONUS Submunitions, and is provided with base bleed system to reach ranges of 35km. Two Submunitions are carried in each shell, covering an area of 200 m’ in radius. The BONUS submunition deploys two “wings” which stabilize its rapid descent path and fast spin required for target scanning. BONUS acquires a target by multi-spectral infrared signature. BONUS II, which will enter production in 2005 will also add a laser radar (LADAR) for improved aiming into a target shape generated by a laser radar (LADAR) sensor. The fusion of spectral and target profile enables BONUS to separate between combat-worthy targets, damaged or burning targets as well as decoys. Each submunition is equipped with explosive formed penetrator (EFP) striking the target by top attack. BONUS II is equipped with improved IR sensors capable of engaging targets with reduced IR signatures and countermeasures. BONUS is in production since 2003. Over 1000 BONUS shells have already been delivered to the French and Swedish armies, and current production programs are scheduled to last til 2007

Dec 2, 2004

MBDA is developing a range extension kit for the SDB designated Diamond-Back. The kit features a tandem-wing design which integrates with the weapon guidance. When stored and carried by the aircraft, the wings are stored in a compact assembly on the back of the weapon.

When released, the wings are extracted to form a diamond shaped structure deployed extending the weapon’s footprint over 20 times, compared to a basic weapon. This capability allows a single platform to engage multiple targets dispersed over a large area. MBDA plans to extend the Diamond Back kits to support 500 lb, 1000 lb and 2000 lbs JDAM munitions.
