MLB Co. (USA)

A variety of methods have been proposed to increase the safety of these convoys, including constant airborne surveillance of the convoy and convoy route using unmanned aerial vehicles. MLB has developed and tested a new convoy-following mode of operation for its Bat mini-UAV. The concept is based on automatic coordination between the convoy and the UAV, by means of GPS location signal, relayed from the convoy to the UAV, which coordinates its flight with the convoy while automatically aiming its gimbaled camera. The focus point of the camera can be on the vehicle itself or a point of interest at an offset distance. The UAV updates its flight path continuously to keep its sensor aimed at this focus point. The UAV will follow the convoy wherever it goes, without preplanning or maneuver restrictions. For example, when the convoy stops, the UAV automatically enters an orbiting mode and keeps its camera fixed on the stopped vehicles. When traveling at speed, the Bat moves into fixed formation but aims its camera at a desired location relative to the convoy. Video from the Bat is received in the convoy vehicles and may also be sent back to a stationary base.

With the introduction of inertially aided weapons, such as the GBU-31 Joint Direct Attack Munition (JDAM), and the AGP-68(V)9 SAR imagery, the F-16 gains an enhanced capability for all-weather precision strike from standoff distance. The aircraft can also deliver the AGM-154 Joint Standoff Weapon (JSOW), and CBU-103/104/105 Wind Corrected Munitions Dispensers. So far, the use of such advanced precion attack weapons capability was available in the IAF only with the Boeing F-15I (Raam).

By 2005, the IAF is expecting to complete acceptance testing and fielding of the RAFAEL SPICE guided weapon kit for Mk84 bombs. Later, the Israel Air Force is expecting to get the RAFAEL Have-Lite standoff attack missile, which will further enhance the range, and survivability of these aircraft. Current versions of F-16Is are equipped with the Python 4 close range (dogfight) all aspect missile, and AIM-120A (AMRAAM) Beyond Visual Range (BVR) missiles. Pyhon 5 a fifth generation of the air/air missiles, currently undergoing advanced flight testing, are developed by RAFAEL as full sphere air/air missiles, which will offer extended range capability both at long range and short range engagement. The missile has a unique lock-on after launch capability, which enables its employment over long ranges, as well as at chasing the launching aircraft. SPICE is an advanced, autonomous navigation system that can be added on to conventional Mk-83/84 weapons, transforming them into autonomous, precision weapons. SPICE uses a combination of inertial and scene matching navigation to home-in on point targets that have distinctive shapes. Since the system uses a combination of navigation methods, is immune to GPS errors and jamming.

A future addition will be the employment of the RAFAEL/Lockheed Martin Have Lite missile. A derivative of the Have Nap, which is already in use with the USAF, and the air forces of Israel, Australia and Turkey, Have Lite enable improved day/night capability, operation by a single pilot, and is adaptable to smaller platforms such as the F-16. The missile offers high precision attack capability of time sensitive targets, as it enables “man-in-the-loop” control, at the terminal phase of the mission, by the use of imaging homing sensor and a two-way datalink to the transmit a real-time image of the target to the controller. The controller can decide what parts of the target should be attacked, and instruct the missile to aim to these points.

Jan 28, 2005

Allied Aerospace developed the iSTAR family of high speed, vertical takeoff and landing (VTOL) UAVs utilizing Lift Augmented Ducted Fan (LADF) system in response for the US Army Organic Aerial Vehicle (OAV) program. The design concept is simple and efficient and makes use of lightweight composite construction techniques. The structure is comprised of an outer duct enclosing the fan system, centerbody containing the avionics and engine, fixed stators and movable vanes operated by actuators, performing thrust vectoring. The engine is housed in the centerbody, and fuel tanks are located in the forward section of the duct. A variety of payloads may be carried in the nose, tail or duct of the vehicle.

Unlike other VTOL UAV’s, the iSTAR utilizes the airfoil-shaped duct to provide augmented lift during low and high-speed cruise. Vehicle control is provided by thrust vectoring resulting in a highly stable and controllable vehicle during all phases of flight. The company is currently developing a 23 cm diameter back-packable Advanced Concept Technology demonstrator (ACTD) the iSTAR UAV, under a DARPA contract, developed under the MAV and OAV programs. The small UAV will be able to carry EO payloads, TV, infrared and acoustics sensors. The US Army is also considering deploying the UAV from autonomous Unmanned Ground Vehicles (UGV).

Command, Control & Communications, Situational Awareness

Traditionally infantry operated in small units such as squads, companies and platoons. While ancient armies used larger formations to aggregate firepower, enhanced communications and devastating firepower of the modern age dictated different tactics for infantry units. In practical terms, allocation of communications determines the smallest size of combat element, which can be controlled as a coherent unit. In most regular armies, the squad is the smallest tactical level unit. Below the squad, only better equipped Special Forces operate in smaller teams. In most recent conflicts, infantry formations were controlled by voice and visual signals commands, shouts and whispers. Lack of communications has sofar limited dismounted infantry operations due to command and control limitations. As they dismount their Armored Personnel Carriers, individual soldiers and sub-squad teams could only disperse within shouting range from each other, to deploy firepower in mutual support and coordinate their movement.

Intra-squad communications significantly improves infantry operations. For the first time, independent sub-squad elements can be employed and coordinate their activity and firepower. Mutual fire support between and within squads can be controlled. Improved situational awareness and reporting provides better real-time intelligence and information gathered in real time. Modern intra-squad specialized Personal Role Radios (PRR) offer effective communications within the squad and between combat teams, enabling effective dismounted infantry operations at a level previously reserved only for Special Forces.

Digital information is usually displayed on hand held computers and ruggedized Personal Digital Assistants (PDA). These devices provide unprecedented situational awareness and access to information. PDA devices used by dismounted infantrymen and commanders to provide situational awareness combine integrated navigation, observation and orientation devices, utilizing optronics, digital compass and GPS systems and laser rangefinder for combat orientation and coordination. Such PDAs are running mission or role-specific applications linked to data-enabled PRRs or hand held data-enabled combat-net radios, operated by squad and platoon leaders. These computers are presenting maps, aerial imagery, sensor data, intelligence information etc. They generate and distribute standard reports. Whiteboard application allows commanders to share common maps, overlayed with mission-specific information and graphics sketched by each member. Using this facility, commanders can coordinate planning without gathering at vulnerable locations. Other applications are provided to rapid response units such as SWAT and mobile guards, guided by ground and perimeter protection sensors. Provided with own position, target locations, images and navigation instructions, such applications optimize their movement providing the shortest (distance) or fastest (terrain, road condition etc) intercept routes, gaining optimal engagement parameters. Similar PDAs provide remote controlle of sensor systems, including autonomous ground robots, (UGV) miniature UAVs (MAV), unattended ground sensors, and even remotely controlled weapon’s platforms.

Infantry weapons firepower enhancement is provided by more accurate improved performance of kinetic ammunition, of advanced multi-purpose munitions such as 40mm grenades and other lethal and less-than-lethal means. The use of optical sights, including red-tot reflection and magnifying optics (x1.5 – x3) improve target discrimination in daylight and nighttime use. Night combat is still considered advantageous for the superior equipped regular forces.

Lightweight night sights include daylight reflection sights adapted to night vision devices, or dedicated night sights integrated with image intensifiers (I2) or thermal sights. Laser aiming lights complement night vision devices offering accurate coordination of fire, at close ranges. Thermal sights are heavier and more bulky but they provide significant advantages as they are not restricted in operations in total darkness such as in underground facilities or caves; they also provide significant advantages in target discrimination. Another advantage of modern sighting systems is the ability to couple electro-optical sights with video communications, improving training, control and coordination of forces, as well as aiming and firing behind corners or obstacles. Systems are offered as complete solutions such as CornerShot, while others are available as add-on kits for existing weapons. Optical sights, and Sight/Camera combinations are becoming a standard issue for all future infantry combat suits.

Further improvement in firepower is provided by fire control systems (FCS) for assault rifles and support weapons, including long-range sharpshooting weapons, and support weapons such as 40mm grenades. For small arms, FCS are provided by miniature embedded computers and displays integrating compact laser ranging systems. Systems include electro-optics for target acquisition and marking, range measurement equipment coupled with the optical sight, to project a ballistic corrected aim-points for accurate long range engagements. The use of such integrated FCS enables firing of pre-programmable time-activated air-burst munitions, for enhanced effect against soft, or protected targets.

Apart from their additional weight vests block natural ventilation, preventing sweat heat dissipation. Physiological tests have demonstrated that body and surface temperature of soldiers wearing bulletproof vests can rise by up to 2C degrees (4F) after one hour continuous physical workout, compared to those not wearing vests. Since sweat is gathered between the shirt and vest, air becomes saturated with humidity and the body’s natural cooling process renders ineffective. As result, heartbeat and body temperature rise, to extreme levels effecting physical and mental capabilities. The introduction of “breathing” athletic garments,active air circulation or micro-cooling, as well as redesigned protective vests, introducing larger gaps between the uniform and shield could reduce such adverse effects improving the soldier’s sustained physical abilities.

Improving mobility of individual soldiers can be achieved by providing lighter, improved fitting and more comfortable equipment, and optimizing to physiological conditions under which they fight. Infantrymen usually go to war carrying loads of up to 50 kg, including personal and mission-specific equipment. Infantry combat suits are designed to reduce this load below 25kg. Further mobility improvements include providing pads to protect neck, knees, elbows and shoulders. Such pads offer mechanical or ballistic protection and assist the soldier in maintaining positions for extended durations. Another mobility improvement can be achieved by offloading some supplies to onto a small load carrier, be it an ATV or small and maneuverable robotic “mule” which can closely follows the troops.

Jan 28, 2005

Developed By IAI/MBT, the Fireball is a laser homing 120/121mm mortar bomb, (the system also fits into a 81mm mortar bomb diameter). It is designed for first-shot, first hit capability and can be used with rifled or smooth bore tubes.

Firing the Fireball requires no ranging, as the weapon uses a unique guidance method that provides course adjustment by gliding, extending range capability. The bomb to detects the target as it glides to the laser detection “basket”, by GPS navigation, where it acquires the target and diving for the kill. The target’s GPS location is fed to the bomb before launch and provides for improved hit accuracy over standard mortar bombs, when laser designation is not available. With laser designation, the bomb can reach an accuracy of 1 meter CEP or less, attacking stationary or moving targets. Fireball uses various warhead fusing options – fragmentation, against soft targets, percussion against armor and penetration type for defeating bunkers and targets inside buildings. The weapon is designed to score a single-shot target kill in urban environment, utilizing a steep trajectory minimizing collateral damage. Due to the unique aerodynamic design, Fireball has almost twice the range of conventional mortar bombs, (up to 15 km).

The system is currently in development stage. All its critical components have already been tested under high G loading and actual mortar firing. further system tests are planned soon. A variant of the Fireball is also considered for tube artillery (152, 155mm).
