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.

IMI has developed a GPS based guided 155mm artillery projectile which corrects its trajectory in two dimensions (range and azimuth). The system is implemented as retrofit for existing ammunition, with introduction of GPS/IMU guidance, navigation and control subsystems, controlling canard winglets for aerodynamic control. The canards and the “Pure Heart” guidance system are deployed after the apogee point, to gain maximum range.

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.Skylark has since entered operational service with selected IDF units, used for operational testing and doctrine development and evaluation.During the Second Lebanon war in July-August 2006, Skylark mini-UAVs were operated by IDF units performing close-in reconnaissance missions in support of the ground forces, providing valuable real-time intelligence, due to their low acoustic and visual signatures, Skylarks were able to operate at very low altitude practically undetectable.

In 2005 the Australian MOD selected the Skylark to support the deployment of Australian forces in Iraq. Six systems were procured and deployed to Southern Iraq. In September, 2006 Thales Canada announced it has been selected by the Department of National Defence Land Forces to deliver a mini-UAV system based on Elbit’s Skylark technology. France has also procured the system for its Special Forces. Sweden and the Netherlands are also evaluating the systems, operating small quantities bought for operational evaluation. By December 2008, the Israel Defense Forces has selected an enhanced version of Elbit System’s Skylark mini- UAV for operation at the battalion level.

The original Skylark I used a miniature gyro stabilized payload weighing only 500gr. The payload was developed by Elbit Systems specifically for MAV applications. It consists of a daylight color CCD. When fitted with night-camera, the payload’s weight doubles to one kilogram. Payload-vehicle integration enables simple and intuitive operation in holding position, as the payload “looks” at a designated point while the UAV circles above to maintain a continuous cover, and camera guide, where the user designates a target or rout to be followed by the payload and aircraft. Image obtained by the camera are overlaid on the integrated map situational display. The Skylark 1 LE uses a different payload called STAMP stabilized miniature payload developed by Controp, available in daylight, night, uncooled thermal and HD configurations.

The new Skylark 1LE configuration offers many enhancements over the original Skylark, primarily 50% increased endurance (3 hours), operational altitude (- 700 ft. to +3000 ft above or below the takeoff point), operational ceiling of 15,000 ft and extended mission radius of up to 15 km, (50 – 100% increase over the original model). The wing span has been increased by 70 cm to 2.9 meters and maximum gross takeoff weight increased by 600 gram from 6.1 (6.3 in the night mission configuration).

While the small UAV is simple to operate, as it is guided autonomously throughout the mission (even in GPS denied terrain) Elbit Systems is offering an optional integrated video simulator to improve training, enabling operators to better understand and plan a mission, based on realistic views of the expected target. Other optional enhancements include an auxiliary operating console, to be operated at the battalion command team.

Many armies are currently modernizing their air defense assets. Current systems are obsolete today, as they rely on armament systems developed and fielded in the 1960 – 1980s. Modernizations and acquisition of new systems target various aspects of these air defense weapons by improving their capabilities against sophisticated threats. This includes enhanced target detection, tracking and engagement under intensive ECM and adverse weather conditions, and the use of passive sensors or introduction of multi-sensors (active/passive). Multi-weapon (missiles and guns) combinations, on a single platform are favored. The latest trend is adding networking capability, combining multiple sensors, firing units as well as interjacent, but different weapon systems. Networking enables fire units to share and coordinate operations on a wider scale, while retaining high level of independence, ensuring continuation of operation, while under attack.

A typical deployed air defense system utilizes sensors, communications and mobile or relocateable missile launchers. All the system’s elements can be remotely operated from regional battle management & control centers and interface with the network via data-links and wireless communications. The sensors include wide area coverage by radar, reinforced by active and passive sensors – such as infrared search & trackers (IRST) and passive radars (detecting and localizing electronic emissions from aircraft and cruise missiles).

Missiles dedicated for such network centric systems often use Lock-On After launch targeting techniques, which enable the weapons to be launched “blind”, or broadly toward a “kill-box” where the target is expected to be. The final target data and intercept parameters are sent to the missile via datalink during the flight, and are further updated before the terminal intercept, to respond to potential evasive maneuvers and countermeasures dispensed by the target. Another advantage of networked air defense elements is its capability to engage a single target by several missiles, from different directions, therefore gaining high probability of kill. This capability is especially important when defending against saturation attacks. When tasked against multiple attacks, missiles can be retargeted in mid-course toward other airborne threats, when the primary target has been destroyed by one of the missiles, utilizing its extended range for mid-course update capability.

Another common feature for network based air defenses is the use of the Vertical Launch (VL) system. This capability utilizes a thrust vector flight control system, that position the missile quickly after launch, at a medium altitude and in the general direction of the target. From this position the missile has superior acquisition of the target in short range engagements. Typical VL systems can launch multiple missiles to engage targets at different sectors, in quick succession. VL capability also eliminates the need for complex, heavy mechanical traverse and elevation systems, required for missile positioning. VL is utilized with many modern missiles including the SAMP/T (Aster 30), Mica VL, Umkhonto, Defender (Barak I), Barak NG and IRIS-T SL. Non VL systems offer other advantages, including rapid response rates in short range engagements, where pop-up targets, missiles and guided weapons are intercepted. Typical non VL systems are the Raytheon / Kongsberg SLAMRAAM, RAFAEL/IAI SPYDER, and Pantsir S1. In order to provide full coverage, such systems are commonly assigned specific defensive sectors of 120 degrees or less.

Further into the future, more revolutionary, directed energy weapons such as the Mobile Tactical High Energy Laser (MTHEL) will probably become the first mobile directed energy weapon to be able to destroy tactical airborne threats in midair. MTHEL type weapons are expected to provide an air defense shield for expeditionary forces and civilians areas which are exposed to a threat of rocket, mortars or artillery attacks.

Further enhancement of the integrated air defense systems approach is the layered air defense concept, which encompasses various systems into an integrated “near zero leak” air defense. The layered air defense system protects a site by defeating multiple attacks of various types of armaments. Layered air defense systems usually consist of three tiers – the extended range combat layer, where short to medium range missiles engage targets such as attack aircraft and unmanned platforms flying at medium to high altitude, and attack aircraft or cruise missiles flying at a low to very low level. The systems operated at this layer must retain “look-down/shoot-down” operating capability, by screening targets against ground clutter. This capability should be provided both to the sensors, guidance systems and weapon systems. This protection level should also be able to engage enemy combat support elements, such as electronic surveillance and target designators.

The second “close-in” combat layer, which employs radar controlled guns and Very SHO Range Air Defense missiles (VSHORAD) missiles, such as SA-7/14/18, Stinger and Mistral, should also provide anti-missile protection. These weapons should target the precision strike weapons which, having penetrated the first layer, are threatening the defended site. Typical targets engaged at this level are guided weapons, UAVs, unmanned attack vehicles and gunship helicopters. A mix of systems is appropriate at this level. Most missiles are effective against aircraft and helicopters, while advanced automatic, air defense guns could be efficient against guided weapons, when equipped with advanced systems such as the Russian Tungushka or Swiss AHEAD technology.

The integrated gun-missile systems (such as Tunguska and Pantsir) offer an impressive capability, especially for point and tactical mobile air defense. However, even with their formidable firepower, such systems cannot act independently. Some analysts are questioning the claimed effectiveness of the 30mm gun at maximum range (3,000 – 4,000 meters), where its capability against small targets (missiles guided weapons and helicopters) is questionable, as kill probability drops well below 50%. With such low yield, the air defense vehicle has an inherent “dead zone” at ranges between 1,500 – 2,500 m’, where the hit probability of the gun drops sharply and the missile cannot engage the target. Therefore, mutual coverage of firing units should be employed to eliminate this deficiency.

The progress of modern air defense systems is being augmented by the modernization of active, passive and networked air defense sensors.

The devastating effect of modern airpower was demonstrated repeatedly in recent conflicts – in the continued confrontation in Iraq, from 1991 through 2003, the successful application of allied airpower brought some analysts to argue that airpower alone could win a war. However, military planners are less enthusiastic about the airpower’s “silver bullet” and see its best application as part of a joint operation, extensively networked with combat formations on land, at sea and in space. For armies other than the US, the air warfare demonstrated in the two recent conflicts with Iraq was somewhat of a peek into the distant future – and not a realistic scenario they can “copy and paste” into their operational planning. The coalition forces had several unique advantages – political and technological – on their side. These included the decade long ability to pound the Iraqi air defenses, by offensive patrols operated over the “no flying zones”, the use of stealth weaponry, including strike aircraft and cruise missiles, during the initial phase of the conflict and virtually unlimited access to intelligence information, provided by platforms operating beyond the reach of conventional defenses – including spy satellites of various types and high flying UAVs like Global Hawk UAVs. A more restricted use of the same assets, during the Kosovo conflict, was executed under strict operational and political limitations and yielded less dramatic results.

In 100 years of operation, harnessing leading edge technologies and advanced science, airpower has matured and became efficient, precise and devastating. Most evidently since the end of the cold war, the characteristic profile of the aerial threat changed dramatically, from direct, over the target attack by large masses of bombers, or nuclear attacks with long range ballistic and cruise missiles, to attacks by a small number of precision guided weapons, launched from aircraft beyond the effective range of the target’s defenses. Cruise missiles have also evolved, to become stealthier, fly lower, faster and attack with higher precision. Unmanned aerial vehicles are maturing as well, and are expected to replace some of the manned attack missions in the near future. The main differentiators between modern and past capabilities are the growing separation between the attacker and his intended target, by the use of autonomous or guided, standoff weapons. Supporting technologies are ensuring high probability of target hit, by evading detection of the strike aircraft and the attack weapons, by the application of stealth techniques, use of electronic warfare for confusion, deception and seduction of enemy defenses, and the suppression and destruction of radars and air defenses, prior to the attacks of key strategic targets.

In some combat scenarios, dedicated weapons are tailored to challenge the target’s characteristics, defenses and countermeasures. For example, point targets such as air surveillance radar sites, command centers and communications nodes, are being targeted by a wide range of high speed, anti-radiation missiles, some of which can “memorize” the emitter’s locations even after the radar shuts down trying to evade such attack. Precision guided munitions are employed in attacks of fixed sites. Stationary targets, whose locations are known, are targeted by autonomous weapons that can sense the targets at the predicted location – modern cruise missiles will fly autonomously and seek the target by their integral sensors as well as scene matching techniques. Typical attacks are performed from long range and high to medium altitude, to achieve maximum standoff range. It is expected that by the year 2010 half of the attacks of such targets will be performed by autonomous weapons such as cruise missiles and Unmanned Combat Aerial Vehicles (UCAV). The remaining half will consist of manned missions, utilizing standoff precision guided weapons, to minimize the risk for the attacking aircraft. The modern technology enables attacks of “surgical” precision, with smaller weapons, resulting in lower consumption of munitions, increasing the total number of attackable targets. Due to the use of such smaller warheads, these “surgical” weapons cause less collateral damage and therefore, more targets can be engaged in or near civilian environment, including power, energy and communications centers, as well as the classic military targets.

Effective air defense systems are imperative to contain such threats. Therefore, each of the recent campaigns began with the crippling and destruction of enemy air defenses, starting from blinding and destroying the “eyes and ears” – radars and command centers, following with a systematic hunting and destruction of Surface to Air Missiles (SAM) and Anti-Aircraft Artillery (A3).

Multifunctional structures will provide attractive benefits for UAVs, with unprecedented weight/power ratios. One approach studied by DARPA for multifunction structures is the monopolar proton exchange membrane fuel cell, which can be shaped into a UAV airfoil skin.

Monopolar fuel cells differ from bipolar (conventional) fuel cells by having the anodes of multiple cells sharing a common hydrogen filled internal volume as a manifold. The cell’s cathodes are the outer surface, open to the air. Individual cells are interconnected by metal conductive elements, with a single metal grid serving as the current collector and electrode support for the anode of one cell and the cathode of the next cell.

Fabricated multifunctional structures achieved an active fuel cells area of 85 % of the external surface, with an output of 1 W/gr. or 100mW/cm2). When applied to the skin, wings and antenna of the MAV, the generated power levels could be sufficient to power a MAV. By proper selection of materials, it can be sufficiently strong that no additional reinforcement is required.

Another feature of this multifunctional structure is the use of an integral metal grid, for effective electromagnetic insulation. Therefore, the structure can be used as an antenna, for communications or as part of a detector payload. Different approaches are used to develop multifunction structure plus power. A constant mass aerodynamic shape structure-battery is being developed based on Telcordia’s PLiONTM battery cells to be used in an AeroVironment’s Black-Widdow MAV. Another approach is studying constant shape autophagous (self consuming) structure fuel, consuming solid fuel elements which provide structural stiffness until they are transformed or consumed for propulsion. Other approaches consider Variform – variable mass structure-power, utilizing inflatable wing structure that collapses in a prescribed manner to maintain aerodynamic function.

Dragon Eye Miniature Aerial Vehicles were operated in operation Iraqi Freedom (OIF) throughout the war, flying mostly over flat, open desert, small towns, and cities and over the edges of Baghdad. Many missions successfully countered windy and sandy conditions. Most flights were unplanned, responding to opportunities and specific tactical requirements. Some missions were planned but not executed due to the rapid operational tempo. The majority of units kept Dragon Eye as a battalion asset with missions tasked by the battalion commander, intelligence officer, or higher command level. Only one unit used Dragon Eye at the company-level. This unit used Dragon Eye the least, as the company commander was too busy with his missions and did not have the staff and specialists to support UAV tasking plans. The most proficient operators for the MAV systems were those with prior intelligence or reconnaissance background, as they had experience in analyzing and reporting what they could see in real time. Dragon Eye units coordinated flights with the battalion air officer or company forward air controller. Coordination included the determination of maximum altitude, keeping to one side of a particular road etc.

Among the missions flown by Dragon Eyes during OIF were point and area reconnaissance, confirmation of other intelligence sources, survey of city area, before the entry of forces, reconnaissance of bridges and routes, supporting mounted and foot patrols, identification of suspected enemy forces, to eliminate fratricide, battle damage assessment and force protection for convoys. The sensors used proved effective for showing people, vehicles, tanks, APCs and guard posts. However, these sensors could not identify people, except by their actions or tell if they were armed, find what effect friendly artillery had on an enemy position, or classify some vehicle types.

Fast Patrol Boats Requirements and Capabilities

Since coastal security units have to secure the entire coastlines, an important parameter is the cost and size of the fleet. Long meandering shorelines and islands often offer many hideouts for infiltrators and mask them from radar detection. Effective security of such coastal lines and waterways require constant surveillance, by airborne, coastal radars and electro-optical means, and frequent patrols that can re-visit every area frequently, and at the same time, respond to any alert raised by the surveillance elements, under all visibility and sea conditions. On such missions, patrol boats are required to maintain their positions for over 24 hours, depending on the number of boats and the number of sectors under protection. The boats should be designed with minimal draft, to allow operating at the shallow coastal water, and be less confined by reefs.

To facilitate endurance, range and sea-keeping capabilities, medium sized boats (+20m) are frequently used while smaller boats are also utilized for shorter missions. Most patrol boats use conventional aluminum hulls, which ensure long service life, simple and maintenance and repair. Several ship constructors are already offering FPBs made of composite materials. Composites are offering attractive weight and construction saving, which directly contribute to lower cost and higher speed but these materials can also be affected form extended exposure to extreme environmental and physical conditions. Some structures, especially those made of glass fibers also absorb water and become heavier over time. Composites promise a great future for faster and lighter patrol boats, but at present, the limited life-cycle experience with composites hulls have so-far limited the acceptance of such boats to few innovators.

Patrol boats are armed with machine guns, are effective at very short ranges, due to the instability of the platform. Stabilized weapon stations for heavier armament (20-35mm guns) include electro-optical weapons director, they are remotely operated from a dedicated console, which enable the accurate engagement of targets at much longer range, therefore making the weapon effective both for deterrence and engagement of targets. Remote controlled weapons stations such as the Mini Typhoon developed by RAFAEL are now offered for 0.5″and 7.62mm machine guns and grenade launchers, and enable accurate engagement of targets from the protected bridge.

Equipped with advanced optical and thermal surveillance systems, patrol boats can detect targets at extended range, especially at night. While the target can be faster than the PB, the patrol boat don’t have to outpace its target, but track the target and coordinate the engagement or intercept from a distance, without engaging in a fast chase. They can plan such engagement with interception profile that will enable them to close in faster, and be at the most advantageous position to hit the target, while being protected from incoming fire, if forceful action must be taken. The important factor in such chase is the persistence – the ability of the patrol boat to cruise at maximum speed, and outlast the opponent on long and fast cruises at high sea.

Since missions are long, it is important that the crew will be able to operate fresh and ready during the entire mission, even at high sea condition, while the opponents, sailing on smaller boats, will suffer much more. The boats also have to be large enough to accommodate, detain and interrogate the crew and passengers of the intercepted target. It should also be capable of towing at least small boats.

In order to deal with such threats, which became even more threatening after 9/11, law enforcement organizations draw a clear distinction between “outlaws” engaged in illegal fishing, smuggling and illegal immigration, “and “security threats”, which usually include insertion and support of land based activities of guerillas and terrorists, insertion and extraction of intelligence agents and special forces, as well as offensive activities (mining and sabotage of ports and waterways, and attacks on marine and naval units). The distinction is important not only for mission classification, but also to employ different rules of engagement, which dictate different mission profiles, and may require specific characteristics and equipment of the patrol boats, coastal support elements etc. Furthermore, smugglers usually use small, commercial speedboats for the trafficking illegal goods, drugs or passengers. They rarely use firearms when intercepted, and try to outrun the interceptors in the open sea or in rugged coastal area, where heavier patrol boats cannot maneuver freely. These targets can be easily overcome by patrol boats, if they are caught, but since smugglers have access to faster and lighter boats, such interception must be carried out by several boats, that can block the target’s evasion routs. Firearms are rarely used in such incidents.

In contrast, terrorists try to disguise their moves as innocent traffic, either fishing, sports or merchant shipping. They pose a serious threat to civilians, as well as strategic targets at sea or near the coastline. They may also target the military assets such as naval vessels or the patrol crafts themselves. These targets should be identified, based on intelligence and other characteristics, as early as possible. In order to prevent terrorists from carrying out operations from the sea, they must be hunted down at long distance from any potential target, including patrol crafts themselves. As the case with every hunting activity, it is important to bring all the advantages to the side of the interceptor – long range detection and identification, at all visibility conditions, situation assessment (is the target armed? How many are on board?).

Coastal security and counter-terrorist operations differ from conventional coast guard activities, especially in the use-of-force dimension. However, since such activities are performed in a routine and peaceful environment, security forces must be able to employ effective but very precise firepower, in order to avoid casualties and collateral damage. The use of advanced sensors, stabilized weapons, and non-lethal means provide more flexibility levels for security forces, to handle potential targets in most operational conditions.

Above: Concept view of the new MRTP 33, a stretched version of the MRTP 29 boat, in service in the Turkish Navy. Below – The Russian Mirage FPB boat. Bottom: Interceptor DV-15 Fast Boats.

The growing popularity of the use of boats for hobby, leisure and sport, is accelerating the growth of the fast-boat market and the introduction of faster and more advanced vessels. Such boats, when used by outlaws, pose a serious challenge to law enforcement authorities, and, when deployed by terrorists, can pose a serious threat to national security.

Speed is not always the first priority

Speed was always a major requirement for naval and coast-guard patrol boats. In recent years, modern Fast Patrol Boats were introduced with cruising capability beyond 50 knots, utilizing various propulsion methods including gas-turbines powered water-jets, hydrofoils, and combined catamaran-air-cushion designs. Hydrofoils offered impressive speeds but lacked in low speed maneuverability and proved to be highly complex platforms, difficult to maintain and operate at the forward operating locations. Other solutions, utilizing a combination of diesels and gas-turbine (CODAG) also offer impressive speed advantages, at the cost of limited endurance. Interception boats, operated by coast guards and customs authorities, usually require higher speeds, while navies engaged in coast guard and counter-insurgency activities (Israel, Sri-Lanka, India, Philippines, Indonesia etc.) have different missions and requirements. Resulting from initial experience with +50 Knots vessels, some navies have reversed their requirements for higher speed, in a more balanced approach favoring improved maneuverability provided by a combination of diesels powered waterjets or Articulating Surface Drives (ASD), advanced sensors and weapons, extended mission endurance. Another military application is the fast attack boat, designed for defensive and offensive operations in littoral (brown) water. The mission of such boats require speed, maneuverability and load carrying capability which are different from the common patrol missions associated with FPBs.

The pysical security fence is providing the core of the buffer zone security system. This obstacle will be augmented by a wide variety of sensors, weapons and security forces. The Ground Forces Command is preparing the ground work for wide scale deployment of such systems, which will include aerostats, observation towers and UAV patrols. The IDF plans to maintain the buffer zone with the minimum number of units, and will equip them to intervene as rapid response forces, employing all all terrain vehicles, such as Hummer tactical vehicles as well as other wheeled armored vehicles, considered effective for this role. Security forces will be deployed in small detachments at high risk locations, from where they can will be able to respond quickly to every incident along the fence. Even faster response could be provided by autonomous vehicles, guarding specific sectors of the security zone, holding infiltrators until responding forces arrive. The IDF is using sophisticated tactical simulation of the buffer zone, for the operational planning and doctrine development. Such simulations evaluate different combinations of doctrine, tactics, sensors and response elements and assist in formulating the best, cost effective security measures for each sector.

RAFAEL has also unveiled the Wolf multi-purpose armored car, designed for patrols and security missions, protected ambulance as well as logistical support transportation for typical LIC combat zones contingencies.

Two other vehicles shown here were the Armored Tomcar and the new Up Armored HUMVEE mounting an upgraded armour suit designed by Plasan Sasa. IAI/RAMTA displayed two new vehciles, the RAM-2000 and the Explosives Ordnance Disposal Vehicle (EODV), an armored truck fully equipped to operate two EOD robots under LIC combat conditions.

Fratricide Prevention activity: NATO
A four-nation Combat Identification Working Group (CIWG) has conducted field trials for its International Combat Identification Interoperability program at the Munster based Bundeswehr Armour School but so-far, while system evaluation continues, it is dependent on funding priorities. An even more ambitious program to reduce individual fratricide risk is based on the so-called Joint Expeditionary Digital Information (JEDI) system. This is based on a rugged field palmtop computer, satellite phones and laser binoculars, to pinpoint precise GPS coordinates of foe and friend, and pass the information over satellite phone network to forward control HQ. This equipment, when fielded will allow tactical commanders to track their troop locations during combat, reducing fratricide risk.

One of the problems encountered during development, was the deactivation of the Iridium satellites system and its replacement with Globalstar communications, which requires new adaptation process, taking valuable time and funding, which could be critical.

Fratricide Prevention Research – UK
All British AFV are to be fitted with a continuously emitting “beacon” using an M-band (94GHz) transmitter. The transmission is picked up by “shooter platforms” fitted with high-gain directional receivers. Brits claim low cost and very low power output as main advantages.

Fratricide Prevention Research – France
The French Dispositif d’Identification au Combat (DIC) is aSimilar technology to BCIS, French engineers are currently working to ensure interoperability.

Fratricide Prevention Research – Germany
The German system (D-Band/1.090 Ghz transponder based) incorporates a laser interrogator which emits coded light pulses generated by solid state, low power eye-safe laser. Friendly platforms are fitted with IR detectors, which generate a D band RF encrypted response, picked up by the interrogating platform’s D-band directional antennae. German scientists claim improved target discrimination and potential compatibility.

Fratricide Prevention Research – Israel
The Israel Defense Forces launched several programs to improve the management and tracking of ground forces, both on the low tactical level as well as the theater and operational level. Since the 1956 war the IDF implemented various signage to mark its own forces, and improve coordination between air and ground elements. Currently, activities are focused at improving the identification and coordination between infantry forces operating in urban terrain (MOUT), where recent misshapes and combat losses have demonstrated the urgent need for such capability. Among the systems used are the Combat Identification System (CID) for infantry troops, and Automatic Soldier Tracking System (ASTS) which collects an automatic situational picture of all forces at a certain area. Other efforts are aimed at better allocation of combat zones and improving coordination between neighboring units operated in a small area (such as in MOUT).

Various Israeli companies displayed new miniature UAVs developed in response for the IDF requirement for mini UAV for the battalion level and below. IAI displayed a wide range of UAVs, including the SpyThere, Birdy and the new Mosquito micro UAV. These three miniature aerial vehicles were designed by IAI’s aeronautical engineering division, as technology demonstrators for IMOD Research and Development Directorate. RAFAEL also brought its new version of the canister launched Skylark, which recently performed its first flight and TopiVision brought their miniature Casper 200 design.

Elbit and GFC both demonstrated the Skylark, which was recently procured for GFC testing. Elbit also brought the Hermes 180, a younger and smaller companion for the Hermes 450 which is currently operational with the IDF. Both models of the Hermes are currently in final stage of competition, as part of the Thales team, bidding for the British Watchkeeper program, where thales is competing against Northrop Grumman.

Larger UAVs at LIC 2004 included the Aerosky, which was operated in support for the IDF by Aeronautics Defense Systems for several years. Also on display were the Searcher, developed and fielded by the IDF and two new UAVs from EMIT – the Sparrow, which is currently in serial production and deliveries to equip one of the Asian Navies, and the Blue Horizon – used by the army of the Philippines.

Unmanned Ground Systems were also demonstrated by the IDF, which is already operating several types of tele-operated systems for specific missions. The ROEE tele-operated weapon carrier is an operational system, which can apidly deploy firing elements and sensors to positions located at high risk, exposed locations. A different robotic system is the Remote Controlled Tractor (RCT), used for clearing and activating mines and roadside explosive devices in sandy soil, in the securing of roads and axis for movement. The RCT is equipped with a video camera and a plough which is pushed forward of the vehicle, where it can detonate or unearth mines and explosives. The IDF is also evaluating a robotic buried mines locating platform. The lightweight tele-operated system has a low ground pressure, which enables it to move over a minefield. It is equipped with sensors which can accurately locate and mark The buried mines. Other small robots are operated bomb disposal teams.
