Jun 26, 2004

Desert Hawk is a miniature UAV system developed by Lockheed Martin’s Skunk Works group. It is currently as part of the US Air Force’s Force Protection Airborne Surveillance System, or FPASS. 20 Desert Hawk systems (out of 48 ordered) are used in Afghanistan by the USAF, to augment the protection of airbase perimeters, searching for suspected vehicles and people with shoulder-fired missiles lurking to attack aircraft. Desert Hawk can fly at altitudes of less than 330 m’ and can see about 10 kilometers beyond the perimeter of the base.

Desert Hawk is constructed of mold-injected expanded polypropylene – a Styrofoam-like material which is flexible, damage-resistant type of foam. Kevlar skids are used on the nose and tail to improve durability. The sensors are carried in the middle of the fuselage, peeking down at the surface through a notch opened in the lower fuselage. Both color CCD or infrared cameras can be used. The GPS antennae and communications links are mounted on the wings. It uses an electric motor and therefore maintains a quiet operation.

Launched into the air by two people using a bungee cord as a slingshot, the mini UAV flies its mission fully autonomously, at speeds of 40 to 80 km/h, following a flight path that has been plotted out beforehand on a laptop using GPS coordinates. The plane can be directed to circle over an area of interest, or the operator can alter its flight path while the plane is in the air. Its payloads comprise of interchangeable systems, including an infrared thermal imaging system for night use, or a set of three color cameras for daylight.

Each Desert Hawk system, which consists of six aircraft, a ground station, and spare parts, costs $300,000. An improved version of the desert Hawk is currently in development. Most of the improvements will focus on system integration, including cooperative target engagement, with UAVs automatically assigned to locate and track targets detected by ground surveillance radars. Of the 48 systems ordered, four have been delivered to the British Army and more are planned for delivery to special forces units. The British system was tested in Iraq, but deemed unsuitable for operations in Iraq as its downlink was jammed by interference from the Iraqi mobile phone network system.

ATMOS is a light weight, truck mounted, self propelled 155mm artillery system. The externally mounted gun accommodate various calibers including 39, 45, 52 cal. Barrels. The system is Integrated with fully computerized systems, achieving accurate navigation, positioning, target acquisition and control. To withstand the gun recoil, the Howitzer rests on its hydraulic rear spades, which support it while firing. Spades are lowered and dug into ground as soon as the Howitzer stops in its firing position.

The gun is operated by a crew of six, transported in a protected cabin. Projectiles and propelling charges are also stowed in a protected stowage, to improve safety and survivability.
The hydraulic power pack operates the Howitzer elevation and traverse gears, as well as the ammunition handling system and the spade’s actuators. The hydraulic platform adjusts itself to enable comfortable loading and firing. Laying operations are being controlled by the gunner from a position, in which he can observe the target or aiming point through the sight instrument and at the same time control the system. The gun can also be slaved to the fire control and ballistic computer, for automatic laying and utilization of complex firing programs.

The ATMOS truck mounted artillery system was recently chosen to equip the Romanian Army, where it will be installed on a locally built 6×6 vehicle. Soltam is cooperating with the local Aerostar Company to fulfill this project. These systems will be designated ATROM.

Jun 6, 2004

IMI introduced a stun cartridge, specially developed to enable tanks to use their main guns in deterrence, without risking the large number of casualties and collateral damage that frequently occur under MOUT combat conditions. The stun cartridge can be used in situations where rapid dispersal of crowd is required, for suppression of sniper fire from residential building, or when hostile civilians are trying to approach the tank. The effective range of the ammunition is between zero to 30 meters, as firing creates the noise and pressure/blast similar to a live cartridge, though without the metal fragmentation. It also produces a cloud of smoke with plastic pellets covering in the proximity of the tank.

The multi effect grenades are using both CS and small explosive charges to provide an unpredicted “surprises”. After throwing the grenade it emits high flow of CS smoke but after few seconds it surprisingly explodes with a stunning effect, accompanied by the dispersion of different contents such as CS powder, rubber pellets, coloring and marking agents, sticky grease mixture or any other material. The grenade is constructed of soft materials, including cardboard and plastic parts to eliminate risk to humans when it explodes. The company also offers a fast rotating “Sprinkler” grenade which turns up to 8 times per second, therefore making it almost impossible to be picked up by the crowd to catch and throw back at the security forces.

The “Black Widow” which was tested as part of DARPA’s MAV program, was a small fixed wing vehicle, designed in a circular platform. Its weight was only 50 gr. half of which amounted to the weight of the primary batteries. The Black Widow was powered by an electric motor that accelerated it to a maximum flight speed of 20 m/sec. In few years, the Black Widow program progressed from a vehicle that flew for only 2 minutes with no payload to a vehicle that could fly 30 minutes, to an altitude of 769 ft, and transmit color video to a base station 1.8 km away. The evolutionary Black Widow platform equipped with an increased wing surface area and wing loading (still within the 15 cm limitation) demonstrated maximum flight speeds of 40 miles per hour. Further improvements in propeller efficiency increased to a dramatic 82%; and 22 minutes in flight duration, using a “heads down” flight control through an on-board color video camera. The Black Widow airframe and propulsion system ultimately evolved to reach 30 minutes endurance, and flight range of 17 kilometers at a cruising airspeeds between 38 to 53 km/h. The control system was capable of “autohold” for heading, altitude and airspeed.

AeroVironment developed a light weight a transportable, Universal Ground Control Unit for the Black Widow, comprising of a control unit with the size of a laptop computer and an antenna. All the relevant data is superimposed on the colored daylight readable video image, as it is down-linked from the vehicle. Information includes the magnetic heading, altitude, airspeed and the health of the MAV. The widow is launched automatically from an expendable cassette pneumatic launcher, about the size of a cigar box.

To extend the communications range of the system, the Widow is supported by an aerial relay installed on another MAV – the Pointer, which will fly higher to accomplish a non-line-of-sight relay system for video transmissions. In this configuration, the Black Widow/ Pointer team can support operational deployment at urban or rugged and mountainous terrain, at ranges of up to 20km.

Climate Control Systems (CCS) and Life Support Systems (LSS) for the new T-90 tank and BMP-2. Similar systems have been installed in the Israeli Merkava tanks. The Indian army is interested in Climate Control Systems (CCS) due to the excessive heat levels experienced in AFVs, which severely impact the reliability of electronic equipment. LSS are utilizing an air conditioning system, which feeds clean, cool air into the fighting compartment. The CCS is suitable for applications where limited power is available, as it utilizes “spot cooling” of selected electronic equipment. Similar concepts are also applied with micro-cooling for the crew, by the use of collective NBC protection and individual cooling suits.

Elbit has developed the Skylark miniature UAVs, a manpacked system designed for tactical close-range surveillance and reconnaissance missions, artillery fire adjustments as well as force protection and perimeter security.

The mini UAV is quickly assembled before the mission and is launched by hand. Recovery is performed by a deep stall maneuver, which lands the vehicle safely on a small inflatable cushion, at a pre-designated point. the cushion is designed to protect the payload on landing. The entire mission is flown autonomously, feeding real-time continuous video and telemetry data to the portable ruggedized ground station. Its wings and tail surfaces are constructed of a lightweight composites, the fuselage tubular boom is also made of composites. The avionics and payload systems are contained in a pod carried below the boom. The gimbaled payload utilizes a daylight CCD or an optional FLIR for night operation, which can be rotated by four gimbals. In February 2004 Elbit won an IDF Ground Forces Command contract to supply the Skylark for evaluation and testing as an organic UAV system, to be operated by infantry units.

May 20, 2004

(HE-MP-T) tank round, designed to provide tank crews a “secondary” ammunition to replace the High Explosive/Anti Tank (HEAT) round currently used by armored forces of most armies. HE-MP-T offers superior performance to HEAT in all missions, except the anti-tank role. The new round provides a complimentary companion to the IMI’s Kinetic Energy (KE) round, designed for dealing with non armored targets, such as bunkers, light armored vehicles, buildings, dug-in personnel, etc. HE-MP-T provides optimal and cost effective ammunition for modern armor employed in a variety of support tasks in asymmetric warfare, fighting in open area and urban terrain.

The new HE-MP-T follows the success of IMI’s Anti-Personnel/Anti-Material (APAM) cartridge, which has become standard 105mm ammunition with the IDF. Its 120mm derivative is currently in development for the Israel Defense Forces and is scheduled for fielding by 2009.The new round follows a similar design and shape, but is equipped with a unitary, enhanced fragmentation high explosive warhead instead of the six submunitions used with the APAM.

HE-MP-T is designed for operation throughout the effective range of the 120mm gun, up to ranges of 4,000 – 5,000 meters. It uses a tungsten fragments envelope to enhance lethality in the anti-personnel role. It uses an electronic programmable fuze setter (IFS) linked to the Fire Control System (FCS), to enable airburst effect over a designated area, penetration of walls, thin armor or fortification (employing time delay) or explosion on impact, using super-quick activation. HE-MP-T is designed as an Insensitive Munition (IM) offering the highest safety and improved logistics.
