    Super Sharp Eyes for the Snipers

    Firing under ‘perfect conditions’, modern sniper weapons, particularly the high power ‘Anti-Material Rifles’ enable a professional marksman to score a ‘perfect first-hit shot’ at long range. Taking advantage of such weapons’ capabilities, snipers are required to accurately hit targets with the first round, under all battlefield conditions, with maximum effective range of their weapon. Accurate range measurement and prediction of environmental conditions (temperature, wind intensity and wind gusts downrange) are critical in producing such first shot hits. “Winds of 5 to 10 miles per hour significantly decrease the probability of a sniper hitting a target, requiring a second attempt, which increases the sniper’s own probability of detection,” said Ron Rex, Lockheed Martin’s One Shot program manager. “Since wind is transparent and gusts are virtually impossible to time and estimate, even a light gust has huge impact on the hit-probability, missing the target by over 1.5 meters at distances as short as 400 meters.” explains Dr. Deepak Varshneya, Program Manager at DARPA’s Strategic Technology Office.

A joint US-Israeli development, under Israel’s Defense Research & Development Directorate (DRDD) management currently under development at ITL, utilizes a cross-wind laser measurement concept, developed by Dr Joseph Shapira from Soreq Nuclear Research Center. This is evaluating fire control systems designed to improve the sniper team’s performance. ITL unveiled a model of this system, dubbed ‘Focus’, designed as a fire control system to be operated by the sniper team spotter, supporting up to eight sniper positions simultaneously. The system employs a laser beam that instantly measures and profiles wind-flow, creating a three-dimensional model used in the ballistic calculation. Focus will provide each sniper with individual ballistic correction, based on accurate measurements of cross-wind downrange, temperature, range and inclination.

    Spotter60 high power targeting gear for snipers. Another device called Sniper Auxiliary Attachment Module (SAM), designed for the sniper team, was unveiled by Carl Zeiss Optronics. SAM fits 6-24×72 telescopic sights enabling marksmen to receive critical information without taking their eyes off the target. SAM has been developed to solve the problem which marksmen have in preparing the rifle while still observing, identifying and targeting a threat. At a touch of a button, users receive menu-guided information on current settings enabling them to easily determine the current position of elevation and azimuth turret settings at night, plus information indicating temperature and air pressure. Data on the weapon-tilt angle and the slant error is also displayed in the user’s field of view. When added with wind direction and speed, this information is used to calculate a ballistic solution. For spotters, the new Spotter 60 provides fatigue-free observation, clarification and precise acquisition of targets at greater distances and over extended time periods . It has a variable magnification range of 20 – 60 power, an optical clear objective diameter of 72 mm and a focus range of 20m to infinity. Spotter 60 uses a MIL-DOT aiming-point sight, which reduces the difficulty in finding a target, usually experienced with such high magnification devices.

    Other companies are pursuing an advanced sighting system, offering automatic down-range wind-correction to be embedded into the sniper scope. Lockheed Martin is one of several companies developing such systems under Phase 1 DARPA’s One Shot program. This aims at removing windage and range errors from the sniper’s performance. The system is expected to deliver accurate aiming solutions at crosswind conditions gusting to over 40 mph, up to the effective ranges of weapons. The ‘One Shot’ sight will provide the shooter with a continuously updated ballistic solution translated into a corrected aim point. DARPA is expected to down-select a single solution for further prototype development. One Shot is expected to offer dramatic reduction in the sniper training and qualification process.

    Elbit Systems introduced several models of the CORAL Hand-held thermal vision system. The basic system is a high resolution, hand-held, dual field of view personal thermal imaging camera with integral GPS receiver, using a 3-5 µm Focal Plane Array (FPA). This lightweight observation unit weighs less than 2.5 kg, is easy to operate and provides excellent image quality. The system’s applications include infantry, scout and perimeter defense missions. The recently introduced CORAL CR derivative of the basic system, is a laser rangefinder optimized for target acquisition. CORAL CR can also function as an integrated night sight for medium range weapon systems or night binocular for light patrol boats and armored fighting vehicle commanders.

    ITL displayed their latest model of Explorer, a multi-sensor, day/night hand-held target acquisition system designed for the infantry commander, forward observer and special operations operatives. An ‘all in one’ system, Explorer packs a daylight (CCD) and cooled thermal imaging system, with navigation, positioning and target acquisition devices. The system enables the detection of a man-sized target, in daylight at a range of 6 km (2.5 km recognition) and 3.6 km at night (1.5 km recognition). The system uses an integral map display for orientation and situational awareness and supports data transfer over net-centric systems.

    Air Defense Modernization at AUSA 2007

    Among the new air defense systems currently under development, the new Stunner missile is one of the future ‘game changing’ systems, promising to introduce unprecedented cost, flexibility and agility to air and missile defense technology.
    Addressing the growing asymmetric threat of short range ballistic missiles and large caliber rockets, Raytheon and Rafael are jointly developing a new interceptor designed to meet this capability gap with the Stunner, an affordable, flexible and effective ‘hard-kill’ defense. The missile was unveiled for the first time in the USA, by Raytheon.

Photo: Noam EshelThe missile is designed to engage missile and rocket threats with ranges of 70 – 200 km. The new system will establish a lower tier below the IAI Arrow 2 missile, which extends the defensive capability to longer range and higher altitude. Known as ‘Magic Wand’ this program will be managed by the Israel Missile Defense Organization (IMDO), which already supervises Israel’s ballistic missile defense program.

    The Stunner uses a multi-pulse rocket motor, agile steering systems and combined EO/RF seeker, providing high sensitivity under all weather conditions and low vulnerability, immune to deception and countermeasures, facilitating effective ‘hit-to-kill’ maneuverability at relatively low cost. Using a ‘fire and forget’ operating concept, Stunners will engage targets along threat trajectories, requiring minimal cueing from sensor resources, ensuring high rate of fire, even during saturation attacks. Further optimizing the Stunner system’s performance, the missile’s in-flight update will provide real-time retargeting. These elements are particularly important to provide Stunner with clear overmatch on any threat, specifically in complex, hit-to-kill endgame.

    The missile will utilize a booster designed by ATK, a multi-mode seeker and multi-pulse rocket motor, developed by RAFAEL. The system could rely on the IAI/Elta Green Pine missile warning radar or the company’s new Multi-Mission Radar (MMR), which is also considered for the short-range rocket defense system, also developed by Rafael. The missiles could be used as ‘stand alone’ systems, using canister, rail launchers or rely on Patriot units, using common container/launchers and battle management systems. By integrating with existing air defenses, Stunner will be able to dramatically improve the survivability of air defense systems, protecting strategic facilities from attacks by short or medium range ballistic missiles and minimize collateral damage from debris.

Photo: Noam EshelA different weapon system from Raytheon addresses close-in protection against asymmetric threats, using the Laser Area Defense System (LADS). Raytheon is developing this capability to expand the defended footprint and complement kinetic energy system capabilities (such as the Centurion CIWS). The system will also provide effective response against unmanned systems and sensors and could augment ship defense with effective countermeasures against floating mines and multiple small explosive boats. The LADS’ effector uses a beam director replacing the 20mm Phalanx gun. The beam director is linked to a commercially available 20kilowatt fiber-laser produced by IPG Photonics. The system is powered by a diesel generator. During the system demonstration phase conducted in 2006, LADS destroyed static 60mm mortar bombs at a range of more than 550 meters.

    Urban Assault Weapon

    The lightweight Urban Assault Weapon (UAW) was displayed by Qinetiq. The company conducted extensive research evaluating various shoulder launched weapon concepts, designed to provide infantry troops with effective urban engagement capability. Qinetiq designed their UAW concept to be lightweight – less than 17.6 lbs (8 kg) but capable to provide multiple effects from a single munition, defeating bunkers, buildings or light armored vehicles.

    The munition is configured around a super-caliber break-in charge and a follow-through blast warhead. The break-in charge has been optimized to perforate brick, block and reinforced concrete walls. The follow-through bomb is lightly encased to maximize the blast effect when detonated, but still survive emplacement through target walls. It will also create a one meter diameter hole through brick and block walls for rapid entry. The projectile has a unique nose probe, erected at firing, to allow the overall weapon length below one meter, whilst maintaining the required stand-off for optimum break-in charge effectiveness. The “plastic” projectile weighing only 3 kg, is built entirely of composite materials. The weapon is designed for employment indoors. The weapon will be effective at ranges of 49 – 984 ft. (15 to 300 meters).

    MAARS Weaponized Robot

    Foster-Miller, Inc. (QinetiQ North America subsidiary) introduced at AUSA the Modular Advanced Armed Robotic System (MAARS), representing the company’s mature concept for operational, weaponized combat robot. MAARS is powerful and agile system designed specifically for the military and first responders. Compared with the company’s current SWORD and TALON robot, MAARS packs a more powerful platform, designed to carry heavier loads including the fully functional Small Caliber UltraLight (SCUL) remote weapon system from Precision Remote, mounting a 7.62 M240B machine gun or a 0.5 Cal Barret high power anti-material sniper rifle.

    MAARS Weaponized Robot

    MAARS also introduces significantly improved Digital Control Unit offering improved situational awareness, command and control. The controller provides improved weapon control functions, better aneuverability, mobility, lethality and safety.

    The complete MAARS system weighs about 350 pounds. The chassis is constructed as a uni-body frame fitted with easier battery and electronics accessibility. Other features include a larger payload bay, higher torque, creating faster ground speeds and improved braking. An EOD MAARS will be equipped with a new manipulator arm having a nominal 100 lb lift capability. The arm can quickly replace the turret mounted M240B weapon, literally transforming from a remote weapons platform to an Improvised Explosive Device (IED).

     

    Modernizing Fire Support at AUSA 2007

    The centerpiece of the fire support systems presented at AUSA 2007, the latest upgrade of the US Army M-109A6 Paladin. Lockheed Martin unveiled the first prototype of the Army’s future hostile fire location radar, EQ-36. Other systems included a range of air defense weapons, including a first appearance in the USA of the next generation Stunner air defense missile, displayed by Raytheon.

    New developments in fire support at AUSA were highlighted through introduction of the upgraded M-109A6 Paladin system. BAE Systems unveiled the latest upgrade for the M-109 self propelled gun, under development for the U.S. Army under a Public-Private Partnership (P3) signed between BAE Systems and the Army’s Tank Automotive & Armaments Command (TACOM), Program Executive Office for Ground Combat Systems, Project Manager – Heavy Brigade Combat Team (HBCT) and the Anniston Army Depot. The new upgrade called Paladin Integrated Management (PIM) program is expected to be carried out during upcoming reset of M109A6 Paladin SP howitzers and M992A2 Field Artillery Ammunition Supply Vehicles (FAASV). These activities will be undertaken by the Anniston depot. The M109A6-PIM is considered to be the most cost-effective method to significantly improve sustainability and survivability, while reducing the logistics burden on the HBCT and supporting fires brigade.

    The M109A6-PIM uses the existing main armament and recently designed cab structure, while replacing outmoded chassis components with advanced elements from the Bradley Combat Systems, to increase sustainability and commonality across the HBCT. The upgrade will also introduce select technologies from the Future Combat Systems Non-Line-of-Sight Cannon (NLOS/C), including an automated projectile loader and modern electric gun drive systems, replacing the current hydraulically operated elevation and azimuth drives, designed in the early 1960s. The electric gun and ammunition handling components, as well as a micro-climate (air conditioning) system, will be powered by BAE Systems’ Common Modular Power System (CMPS), recently elected for installation on Stryker and HMMWV. The system featured on the M109A6-PIM is capable of providing 35 kilowatts of 600-volt direct current which can be used for voltage conversion and can support other higher power loads required within the Paladin platform.

    EQ-36 Counterfire Target Acquisition Radar developed by Lockheed Martin. Photo: Noam Eshel, defense UpdateModern armies, particularly the US and British armies are reevaluating the role of the light mortar, recognizing its contribution to provide close, accurate and self-sustained support at company and battalion level. These small caliber weapons, including 60, 81 and 120mm tubes offer mechanized and dismounted units effective, accurate firepower capable of hitting targets at ‘non-line of sight’ engagement, particularly in urban, mountainous and densely vegetated areas, including jungle or forest. Self propelled mortars operated by the US Army in the Stryker brigades are operated as a self-propelled fire bases, fielding 120, 81 and 60 mm tubes. The British Army is also considering using this concept with its FRES IFS mortar carrier variant, which will include a 60mm and 81mm tubes, with a growth option to 120mm.

    The 60 mm mortars are becoming a popular weapon of choice among peacekeeping forces, engaged in war against terror in Afghanistan and Iraq, where they are rapidly fielded as low-cost, highly effective defensive or offensive weapon to improve the integral fire support of small contingent forces fielded by contributing NATO members. Old generation tubes, including 60mm and 51mm tubes were quite popular in the past, but in recent years were practically shelved due ammunition obsolescence. The British Army already decided to phase out its 51 mm tubes in favor of 60 mm mortars, while the US Army is currently considering a similar move. The Israeli army fields 60 mm tubes with all tanks and heavy APCs as a lesson from the 1973 Yom Kippur war.

    lightweight C-06 60mm mortar system from Soltam. Photo: Noam Eshel, defense UpdateAs one of the innovators in this field, Israel’s mortar expert Soltam Systems introduced a new, lightweight C-06 60mm mortar system offering 20% weight reduction by utilizing forged aluminum base plate, lightweight bipod and highly efficient tube, capable of firing mortar bombs with M-38A1 proximity fuzes, dramatically increasing the lethality of the weapon against unprotected targets, while minimizing collateral damage by using smaller caliber bombs. In fact, a two man firing team can rapidly generate continuous fire for effect within very short time, in direct support of their units. Mortars are usually operated manually at targets visible by a fire director or the firing team. Firing at high precision at a specific GPS location can achieved within less than 30 seconds with this weapon, using Soltam’s hand-held fire control computer, which supports the entire range of tubes, including 120, 81 and 60mm.

    Optically Directed Advanced Munition (ODAM) under development by BAE Systems for DARPA> Photo: Noam EshelDARPA and BAE Systems have more ambitious plans for the 60 mm mortar. At AUSA 2007 BAE Systems displayed the latest model of the Optically Directed Advanced Munition (ODAM), developed under a $9 million program awarded in 2005 by darpa. Under this initiative, BAE Systems is planning to demonstrate a laser-guided, low cost optical seeker for the 60mm mortar. The guidance kit will be designed to replace the current 60mm mortar fuse to improve firing precision. Additionally, research will be done with explosives to improve the effectiveness of 60mm explosive rounds. Accroding to DARPA, the goal is to develop a 60mm projectile with the effectiveness of a 105mm high explosive projectile. If fielded, such systems could improve the effectiveness of small dismounted units, employing precision indirect munitions that can operate across multiple environments, including urban and mountaneous terrain.

    One of the major displays by Lockheed Martin was an operational prototype of the U.S. Army’s new Enhanced AN/TPQ-36 radar, known as the EQ-36 Counterfire Target Acquisition Radar. In January 2007 Lockheed Martin was selected as prime contractor of on this program. EQ-36 will be able to detect, classify, track and determine the location of enemy indirect fire such as mortars, artillery and rockets in either 90 degree or 360 degree modes. The 360 degree mode is of special advantage for force protection in a modern, asymmetric warfare. Such performance poses more challenging task for current artillery location radars, covering a limited 90 degrees sector.

    Ahmadinejad’s Shiite Crescent Kindles Sectarian Violence

    Two years ago, Jordan’s King Abdullah II accused Iran of planning a sinister scheme to employ tactics of intimidation, bribery and militia training of sectarian elements throughout the Middle East, in order to create instability among rival Moslem factions. The king warned that Iran’s quest toward empowering a “Shiite Crescent” stretching from Iran to Lebanon, would initiate the strategic dominance of Shiite power throughout the Middle East. At the time, King Abdullah’s allegations infuriated the Tehran Ayathollahs, who rejected his accusations as totally baseless. But these days, the escalating sectarian violence among Moslem brethren are clearly bearing out the Monarch’s predictions in a unprecedented internecine bloodbath reaching from Iraq to Gaza, via Beirut- all fueled by Iranian fingerprints. The hurried rise of hard-liner Mahmoud Ahmadinejad has certainly served to strengthen that resolve. In recent years, the “republic” has brazenly broadened its influence in Iraq, Lebanon, and in Gaza. Needless to say, the recent expansion of Shia forces in the region has caused the Saudi royal family much deserved anxiety. The hurried attempt by the Saudi king to host talks between the feuding Palestinian groups of Fatah and Hamas to end fighting that has killed at least 30 people over the past three days in the Gaza Strip clearly indicates this growing concern. 

    Iraqi Shi'i Leader  Moqtada Al SadrThe sectarian bloodshed in Iraq, between Arab Shiites and Sunnis, all have the signs of a hegemonic Persian ambition. No one in Iraq exemplifies this better than Moqtada Al Sadr, the leader of its largest Shia militia — the “Mahdi Army” to which the Iranian government is behind shipping components used to make improvised explosive devices for Iraqi insurgents, fighting both US forces and Sunni militias.

    Some of the most violent attacks struck Shiite targets in the Baghdad area this week, as the Islamic sect marks Ashoura, the holiest day in the Shiite calendar commemorating the 7th century death of Imam Hussein. Although Shi’ites are the minority sect of Islam, they form some 60 percent of Iraq’s 26 million people and have dominated the government following the U.S.-led invasion of 2003. Since the invasion, millions of Shi’ites make the pilgrimage to Hussein’s shrine in Kerbala, transforming the Ashura festival into the biggest national day and confirming the ascendancy of Shi’ism. The Najaf province strike came only a day after mortar shells hit the courtyard of a girls’ school in a mostly Sunni Arab neighborhood of Baghdad. An Iraqi police official said that among the alleged 300 militants which had been killed during the fierce weekend battles, included 30 Afghans and Saudi volunteers, possibly recruited by Al Qaeda.

    Meanwhile President Bush has stepped up his response in a last minute effort to curb the escalating violence in Iraq. As hundreds of thousands of Americans march in protest against George W. Bush’s war policies, the president has authorized U.S. forces in Iraq to take whatever actions are necessary against Iranian agents considered a threat to American troops or the public at large.

    Hassan Nasrallah, the Shi' leader of the Lebanese HezbollahThe White House made the announcement last Friday in Washington, claiming that the aggressive new policy is a direct response to intelligence reports, that Iran is supporting terrorists inside Iraq and is providing sophisticated improvised explosive devices (IED) – and other equipment to anti-American. insurgents. On January 10, President Bush accused Iran and Syria of allowing terrorists and insurgents to use their territory to move in and out of Iraq. He warned that US troops would take measures, including seeking out and destroying ” the networks providing advanced weaponry and training to our enemies in Iraq.” According to new orders, US troops in Iraq now have full authority to kill or capture Iranian agents deemed to be a threat. AS result, five Iranians were detained by U.S.-led forces earlier this month after a commando raid on an Iranian government liaison office in northern Iraq. According to Associated Press news agency, the administration said at the time that U.S. forces entered an Iranian building in Kurdish-controlled Irbil because information linked it to Revolutionary Guards and other Iranian elements engaging in violent activities in Iraq.

    In Lebanon, the Iranian sponsored Hezbollah-led bloc’s effort is poised to carry out the first Middle East revolution this century to overthrow a pro-Western government. Although it seemed to peter out over the weekend, intelligence sources estimate that the grand strategic design is to to go forward in calculated stages, rather than a continuous operation. Only last Tuesday, three Lebanese were killed, 133 were injured and the entire country was virtually paralyzed by Shiite cordons on strategic locations, a clear signal of what is in store. The anti-government bloc, headed by Hassan Nasrallah and pro-Syrian allies, Gen. Michel Aoun and the north Lebanese Faranjieh clan, has been encouraged by its initial effectiveness to carry on to the next stage at some unspecified moment. Here too, there is a clear Tehran design to dictate the modus operandi.

    Jihad Islami leader  Muhamed al HindiAs if the internecine Hamas Fatah fighting in the Gaza Strip seemed to have stopped suicide attacks on Israel for a while, the bloody attack by an Islamic Jihad bomber, identified as Mohamed Faisal al-Sahsah, 21 from Gaza, indicated that Iran would not let this temporary lull to continue. Military sources disclosed, that the fingerprints of the newly appointed Jihad Islami leader of Palestinian Jihad Islami terrorist ace Muhamed al Hindi were clearly distinct on Monday’s Eilat suicide bombing. Al Hindi returned to the Gaza Strip on January 19 after a six-month absence in Damascus, Beirut and Tehran, during which his Syrian and Iranian masters appointed him chief of the operations. His former boss, Abdallah Ramadan Shelah, who seemed to have lost some favor to his Tehran masters, was a key member of the Palestine delegation, which held recent talks in Damascus last week, presided by Ali Larijani, the secretary general of Iran’s Supreme National Security Council (SNSC).

    Commenting on the seriousness of the escalating inter-Arab situation, a senior official in the court of Jordan’s King Abdullah believes that “a domino effect is beginning to emerge among those who can exercise a veto and are not necessarily interested in resolving the Israeli-Palestinian conflict, but rather in maintaining the political boost that it gives them. Islamic Jihad has a veto over Hamas decisions; Hamas can impose a veto on PA decisions; Damascus also holds a veto, albeit a partial one, over Hamas’ conduct; and meanwhile Iran seeks to hold a vital position in the balance of powers created by the war in Iraq. This is a strategic chess game, led by Tehran, in which Abbas, Shallah and Meshal are only pawns. Israeli intelligence officials warn that the Palestinians themselves are no longer certain that they have the ability to make decisions independently.

    Panoramic Vision for Armored Fighting Vehicles

    A version of the US Army TUSK upgrade kit for the M-1A2 was on display at AUSA 2007. This version is fitted with two Remote Weapon Stations and a second coax machine gun, mounted over the main 120mm gun. To further improve the tank’s performance in asymmetric warfare GD ATP introduced two types of ammunition for the main gun – the M-1028 Canister round and a high explosive round, coproduced with Nammo.

    A stabilized miniature imaging platform was demonstrated by Carl Zeiss Optronics from Germany. The system uses a dual sensor (CCD and an uncooled thermal infrared imager) mounted on a stabilized, swiveling platform optimized for near-field observation. The system has been selected for installation on Leopard 2, modified for Peace Support Operations (PSO), where two systems will be installed on the left and right sides of the turret, providing 360 deg. panoramic coverage for the crew. The system will be provided with an automatic motion detection system providing threat warning. An optional laser rangefinder complements the system, by installation on armored fighting vehicles, offering 360 deg. view. The system’s weight is less than five kilograms therefore facilitating installation anywhere on the vehicle, including on elevated masts. The stabilization enables the crew to view images on the monitor even when the platform is traveling at high speed.

The sensor includes uncooled thermal and video cameras, for day and night surveillanceunder all visibility conditions. Check-6, a camera integrated into teh vehicle’s headlights and tail lights.

    These cameras are part of Elbit Systems' See-Through-Armor,  providing panoramic, close-in coverage of a vehicle perimeter.  Photo: Noam EshelA different concept of a panoramic vision system was demonstrated by Elbit Systems, introducing the ‘See Through Armor’ (STA), a panoramic observation system which can be embedded into new armor, or installed as ‘add-on’ to existing vehicles, providing the vehicle crews with an omni-directional combat scene seen from within the armored vehicle, when the crew is ‘buttoned in’ with hatches closed. An equally realistic view can be obtained from an unmanned platform. The objective of the system is to improve the crew’s situational awareness under all conditions, including extended ‘silent watch’ missions in areas where close-quarter defense is imperative (including urban areas, jungle etc), where the techniques, tactics and procedures (TTP) dictate maximum force protection with the crew remaining ‘buttoned up’ inside their vehicles for hours. Under such conditions, limited visibility creates ‘dead zones’ attracting attack by hostiles, exploiting the limited visibility by the crew, to hit the vehicle with RPGs or lay down belly-striking explosive charges activated from a distance.

    RAFAEL's Spotlite M gunshot detection system. Photo: RAFAEL.A complimentary sensor that can be applied to panoramic vision is the ‘Spotlite M’ electro-optical fire locator from RAFAEL Defense Systems. The system, unveiled at AUSA 07 provides fully panoramic coverage of the vehicle’s surrounding, with superimposed cueing indicating potential threats based on detection and localization of fire sources, within few seconds from a gunshot or rocket-launch occurrence. RAFAEL plans to complete an integrated vehicular system before year’s end.

    Panoramic vision systems complement remotely operated weapon stations currently installed on many armored combat vehicles. AUSA 2007 was dominated by the Kongsberg Defense’s Protector Remote Weapon Station (RWS), recently selected by the US Army for teh CROWS program. The system provides troops with the ability to acquire and engage targets while travelling inside a vehicle, protected by its armor. It is designed to mount on a variety of vehicle platforms, support weapons such as the Mk19 grenade machine gun with 96 grenades ammunition capacity. The system can also mount a .50 Caliber M2 machine gun with 500 rounds, M240B machine gun with 1,000 rounds and M249 Squad Automatic Weapon (SAW) with 2,000 round capacity. Protector RWS were also demonstrated at AUSA 07 on the M1A2 tank (operated by the commander and loader).

    The sensor suite employs a daytime videoTwo versions of the CROWS Remote weapon Systems installed on an M1A2 tank.

The system features programmable target reference points for multiple locations, programmable sector surveillance scanning and setting of multiple, restricted no-fire zones. The optronic system enables the gunner to view the target independent of gun elevation. Other features include auto- tracking; auto-lead and auto-scan functions.

    The new Protector succeeded the Raven, developed and produced by Recon Optical, originally produced to meet US Army’s CROWS requirement. The system mount has three-axis stabilization for the weapon and sensor assembly, allowing on-the-move target acquisition and fire-burst target engagement. The system also supports manual emergency backup. Potential enhancement includes the integration of sniper location systems and other weapons. The Protector weighs 305 lbs Close-up view of the compact control unit of the CROWS  RWS system. Photo: Tamir Eshel(unloaded, unarmored) and protrudes 28″ above deck. The system can be folded to reduce height by 10″ on transit.

    The Army may have a requirement for an even lighter remotely controlled weapon mount, designed for vehicles with minimal payload availability such as the HMMWV, as well as heavy trucks. This mount is designed for medium and light weapons such as M240B and M249.

    One candidate for this platform is the ROI Lightning, weighing less than 200 lbs (above the roof), including weapon The LW-25 automatic weapon mounted on an R-200 weapon station.

Also evaluated are the integration of CROWS-Lightning and the PD Cue 4 corner acoustic gunshot detection system, offering complete threat detection and engagement capability. Two additional lightweight weapon stations at AUSA were Rafael’s Samson Junior and Elbit Systems ILAW. The Samson is a lightweight member of the Samson family of RWS, designed specifically for light weapons such as the M240/M249 class weapons.

    More Progress with the Future Combat Systems

    Progress was also reported with the US Army Future Combat Systems program, with lead systems integrator Boeing and its partner SAIC completing the Engineering Maturity 1 (EM1) review, a system of systems technical review of the future requirements, designs and tests, capping the program’s first of four major engineering phases. Dennis Muilenburg, vice president-general manager, Boeing Combat Systems and FCS program manager explained that this critical milestone demonstrates that the FCS program has sufficient design maturity to proceed toward the next milestone – the Preliminary Design Review (PDR) scheduled for early 2009. Meeting EM1 on schedule was also an important measure of the team’s technical success as Spin Out 1 capabilities are being delivered for the US Army for testing next year.

    Bradley Fighting Vehicle - technology Demonstrator is a program pursued by BAE Systems, demonstrating how some of the FCS technologies that can be introduced into the current force. Pictured here is an  implementation of warfighter communications and display (using an eyepiece) integrating dismounted troops and armored vehicles, providing the dismounted element full situational awareness supported by the vehicle's mounted sensors. Photo: Noam Esheland EM1 examined initial FCS system designs, functional and performance analyses, software and hardware maturation, Spin Out 1 deliveries, and progress in experimentation and testing since the Initial Preliminary Design Review in August 2006. Final design concepts will be presented during individual system-level Preliminary Design Reviews over the next year and later assessed during the System-of-Systems Preliminary Design Review in early 2009 to confirm they can proceed to final detail design and testing.

    Among these capabilities are the network integration hardware kits, also known as ‘B Kits’, to be installed on Abrams main battle tanks, Bradley armored vehicles and HMMWVs. The kits were delivered to vehicle integrators BAE Systems, General Dynamics Land Systems and AM General, bringing the total number of B-kits delivered to date to 18. Through these interfaces, existing elements of ‘current force’ – heavy and mechanized brigades will be able to communicate and share data with FCS systems. Vehicles equipped with B-kit hardware and software will operate with the Army Evaluation Task Force test and evaluation activities scheduled to begin in early 2008.

    Each B-kit comprises a Ground Platform Communications System which includes a Joint Tactical Radio System (JTRS) Ground Mobile Radio (GMR) and an Integrated Computer System, running the System of Systems Common Operation Environment (SOSCOE) software and FCS’ standard Battle Command System applications.
    This communications equipment will be able to enhance networking capability to the current force, as well as improving integration with unattended sensors and unmanned ground and aerial systems, deployed in support of current and future combat elements. Muilenburg indicated that the networking systems will be fielded together with tactical- and urban unattended ground sensors (UGS) and the non-line-of-sight launch system.

Photo: Noam EshelThe Battle Command and SOSCOE software enables interoperability between systems, prioritizing raw data from sensors such as the Tactical- and Urban-UGS slated for Spin Out 1. It enables data to be displayed on the screens of current force vehicles, providing soldiers with enhanced situational awareness. The software will be integrated seamlessly with the vehicles’ existing software for use in initial qualification and safety release test activities, that are required before soldier testing can begin. A final software release this fall, will enable control and monitoring of multiple UGS fields.

    Heavy Armor at AUSA 2007

    A version of the US Army TUSK upgrade kit for the M-1A2 was on display at AUSA 2007. This version is fitted with two Remote Weapon Stations and a second coax machine gun, mounted over the main 120mm gun. To further improve the tank’s performance in asymmetric warfare GD ATP introduced two types of ammunition for the main gun – the M-1028 Canister round and a high explosive round, coproduced with Nammo.

This ammunition is uniquely effective at very short range, as it discharges massive blast of tungsten ball fragments at the muzzle exit, effective up to a range of 500 meters. The canister round weighs 50.5 pounds (22.9 kg) which is about half the weight of the Flechette that uses small darts, effective at a longer range. Another round being introduced for the 120mm cannon is the 120mm high explosive (IM-HE-T), improving the tank’s performance in direct fire support. This cartridge weighs 25 kg, and packs over twice the explosive weight, compared to standard High Explosive Anti-Tank (HEAT) rounds. The projectile weighs 16 kg and contains 3.2 kg of Insensitive-Munition (IM) type high explosive contained in a fragmenting shell body, triggered by a Point Detonating (PD) or delay fuse, ensuring target penetration. ATP is offering this round based on its cooperation with Nammo.

    LAV-H upgrade program proposed for LAV3 and Stryker vehicles. Photo: Noam Eshel.
    General Dynamics Land Systems introduced a major upgrade for the Light Armored Vehicle (LAV) design, which could be implemented as a mid-life upgrade for US Army Stryker as well as LAV 3s, currently operational with the US Marine Corps and the armies of Canada and New Zealand. The upgrade designated ‘LAV-H’, is proposed to be undertaken as part of major post-combat reset reconditioning. Under the process, the vehicle’s automotive and power plant systems will be upgraded to support a 25% Gross Vehicle Weight increase from the current 42,000 to 55,000 lbs. (25 tons). The vehicle’s curb weight will be 29,000 lbs (13.2 tons). As part of such upgrade, GDLS intends to install a Caterpillar C7 engine and Allison 3200SP transmission.

Note the wide internal  space cleared by the installation of remotely powered weapon station. Photo: Noam EshelAddressing the growing demand for on-board power, a new 500 Amp alternator will be installed, coupled with an expandable and scalable solid-state power distribution and control system. An optional Lithium-ion battery pack could nearly double electrical power storage capacity on board, with the same space claim as the standard vehicle battery pack. The crew will be able to exhaust nearly all battery power without having engine restart failures, relying on the 24V Capacitive Start System offering power reserve for the engine starter, independent of the main battery. The vehicle was demonstrated at AUSA 2007 with a Protector Weapon station mounting a heavy machine gun and a Javelin missile launcher.

    The upgrade also includes a significant increase in protection, with the introduction of enhanced belly protection, hull modifications include reshaped V profile for improved blast resistance. Externally, large appliqué armor modules and redesigned hatches are introduced, improving protection and minimizing vulnerability, caused at the seams between armor modules. Externally and internally, the vehicle has better protection against IEDs, for example, with the introduction of blasts absorbing mine resistant seats (or benches).

    General Dynamics Land Systems-Canada delivered the first LAV-A2 to the US Marine Corps, The A2 is an updated version of the Marines’ Light Armored Vehicle series, which has been in use since the 1980s. In February 2006 GDLS Canada was awarded a contract to upgrade 157 LAVs in six variants, into A2 version. These variants included LAV-25, anti-tank, command & control, logistics, mortar and Nuclear, Biological and Chemical Reconnaissance System (NBCRS). The upgraded vehicles are fitted with an improved suspension, and are readied to receive enhanced armor protection. New safety precautions include an automatic fire suppression system for crew protection.

This platform is a larger version of the wheeled SEP 6×6 developed as the ‘next generation military vehicle system’ program funded by the Swedish Defence Materiel Administration (FMV). According to BAE Hagglunds plans, SEP 8×8 could be available for delivery by 2011. SEP is built on a modular platform, enabling growth potential and adaptation to a wide range of applications. Unlike the 6×6 version, SEP 8×8 uses mechanical transmission, designed to meet FRES requirements. Other SEP family vehicles use electronic transmission. SEP 8×8 was configured as a wheeled armored vehicle with a full combat weight of 24 – 27 tons (curb weight in an APC version is 14.5 tons). This version was originally designed by BAE Systems Hagglunds, competing with the Piranha V, Boxer and VBCI for the British FRES program, but eventually dropped after trials.

No need for welding, cutting or shaping it into position. Photo: Noam eshelBAE Systems displayed its new aluminum-based L-ROD bar armor at AUSA, shown on an RG-33 vehicle. The company was recently awarded a $15.5 million contract to provide these lightweight bar-armor kits for 215 Route Clearance Vehicles operated by the U.S. Army. Under the contract from the Army’s Tank-automotive Armaments Command, BAE Systems will equip RG31 and Cougar vehicles with its L-ROD aluminum armor, used widely on Army Buffalo ordnance disposal vehicles. L-ROD is standard equipment on the Army Buffalo explosive ordnance disposal vehicle. BAE Systems has delivered more than 100 L-ROD kits to the Army, with additional kits slated for the Marine Corps’ Buffalo vehicles. The company also is completing L-ROD designs for BAE Systems’ Caiman II and RG33-series mine-protected vehicles.

    Saab Barracuda highlighted its Heat Transfer Reduction HTR material, originally used to diminish the vehicle’s visual and thermal signature, HTR pragmatically reduces the temperatures inside the vehicles, resulting in less fatigue on warfighters and improve durability and reliability of electronic equipment. A positive side effect is the lesser need for air-conditioning, further impacting power and fuel consumption. Saab Barracuda is currently promoting HTR in the US, after delivering thousands of systems to military users in Australia, Canada, France, Italy, Sweden, UAE and the UK.

    NightHawk – Miniature UAV

    Nighthawk, formerly known as BatCam or Tacmav, is a miniature, foldable unmanned aerial system, is a third generation micro-UAV developed at Applied Research Associates (ARA). 84 systems have already been delivered, with more than 260 aircraft, primarily from the earlier models. Systems were delivered to Air Force Special Operations units and, through the Rapid Equipping Force (REF) to US forces in Afghanistan.

    These small UAVs were tested in combat by the units from 82nd Airborne division, demonstrating good results. The current version is implementing the feedback from the troops and lessons learned during these operations. ARA’s latest version of the micro UAV is the Nighthawk. Utilizing the same folding wing method used in previous models,

    NightHawk is ready to fly as soon as it is pulled from its container. The range of the current version is increased to 10-15 km, and flight duration extended to 70- 90 minutes cruising at speed of 18 – 35 knots. The air vehicle, constructed from tough, lightweight carbon fiber airframe and flexible wings, which can be folded around its fuselage, allowing the entire UAV to be stored in a small tube. When pulled out of the tube, the folded wings automatically snap into place. It weighs only 1.6 lbs and has a wing span of 26 inches. It is designed to operate at an altitude of 200 – 500 ft above ground level, at elevations up to 11,000 ft above sea level. NightHawk can be launched by hand toss, from standing, sitting, prone position or from moving vehicles. To ease tracking, NightHawk is equipped with a remotely controlled visible/IR strobe.

    Nighthawk is can be carried as an ‘assault pack’, weighing only 15 lbs. It is equipped with a modular payload comprising a forward looking daylight camera, low-light camera or side looking thermal sensor. Each system comprises two aerial vehicles contained in storage tubes, carried on the sides of a standard ALICE backpack. The ground control unit utilizes a Panasonic Toughbook laptop loaded with the GCU software and communications kit.

    The first generation of the system, known as TacMav, was developed to meet the requirements of special operations command. TACMAV system includes three aerial vehicles, modular payloads, and ground control unit and communications equipment. The MAV has a cruising speed of 80 kph. The first generation was a 50 cm long miniature drone with a wing span of 53 cm. First generation TACMAV used a payload pod containing two color CCD cameras and a video transmitter, weighing only 40 gram. The total payload capacity of the TACMAV is 80 gram. The user could select forward or side looking camera. 15 frame “snapshots” can be used to recorded target of interest. The battery operated vehicle has an endurance of 30-50 minutes, using rechargeable lithium polymer cells. Higher capacity cells were also considered, extending the mission twofold. The GCU is running standard Air Force Portable Flight Planning System (PFPS) interface for mission planning, supporting pre-flight planning, in-flight updates and manual control.

    In November 2007 Irvine Sensors and Applied Research announced plans to upgrade the Nighthawk’s payload packageusing Irvine’s proprietary thermal and visible cameras. The two companies also plan to modify the Nighthawk to enable tube launching, facilitating operations from vehicular platforms. The command and video datalinks are also to be improved introducing secure wireless transmission. The two companies are cooperating to pursue business opportunities with US MC and Army, as well as other applications and services. Under the teaming arrangement, Irvine Sensors will act as prime contractor for contracts involving Nighthawk-based applications for use on U.S. Army and U.S. Marine Corps mounted combat vehicles, with Applied Research serving as subcontractor. For other applications, the roles will be reversed.

    Type 214 Submarine

    Type 214 submarines were developed in Germany to address the requirements form modern navies for more endurance, without using nuclear propulsion. Unlike classic diesel electrically powered subs, Type 214s are using a new fuel cell system providing an Air Independent Propulsion (AIP). The new propulsion system enables an increased diving depth and overall performance efficiency, through specially built hull and advanced weapons systems. Absence of a diesel engine also provides for minimizing acoustic, thermal and magnetic signatures.

    Type 214 Submarine Specifications:
    Length: 65 m
    Height: 13 m
    Pressure hull diameter 6.3 m
    Surface displacement 1,700 ton
    Pressure hull fabricated from ferromagnetic steel
    Integrated sonar and weapon control system (USUS 90)
    The 214 is equipped with eight full-size swim-out launching tubes in the bulkhead for all types of subsurface weapons, All tubes can launch torpedoes and four are configured with weapon expulsion system supporting missiles.
    Propulsion system: motor by Permasyn, utilizing a PEM fuel cell system

    MULE – Multifunction Utility/Logistics and Equipment

    Lockheed Martin’s Multifunction Utility/Logistics and Equipment (MULE) autonomous vehicle is developed by Lockheed Martin for the US Army Future Combat Systems program. The vehicle is designed to carry the load of two infantry squads, totaling about 2,000 pounds (907 kg), and support troops with water and power sources for extended operations. The estimated cost of each MULE platform (without mission systems) is expected to be US$300,000.

    The Mule will be a “follower” to the human team. Each of the team members will be able to order the Mule to come forward, to support the operation. Otherwise, the vehicle will maintain a safe distance behind the team, waiting for orders. Like its human combatants, the Mule will have day and night thermal sights, while additional sensors, such as forward-looking imaging systems and chemical biological sensors will be installed in a forward payload to support team operations. The mule can communicate with and sometime, deploy unmanned aerial and ground vehicles (UAV/UGV) to give the squad members a true 360-degree image of the battlefield.

    At AUSA 2008 Lockheed Martin displayed the latest configuratio of the MULE which recently received new wheels, utilizing springs made of composite materials, instead of inflatable tires. These wheels are less vulnerable to small-arms and fragments hits, and can operate continuously without replacement or maintenance even after suffering severe damage or hits.

    The MULE engineering evaluation vehicle uses a diesel electric engine powering the six wheels, mounted on independent articulated suspension. The wheels will be fitted with Run-Flat inserts and Central Tire Inflation System for improved mobility and survivability.

    The future system will employ hybrid electric propulsion, with in-hub motors powering each wheel, providing extreme mobility in complex terrain, far exceeding that of vehicles using more conventional suspension systems. The MULE’s unique mobility will enable it to follow everywhere the soldier can go and more. MULE will be able to travel cross country at speeds of 43.5 mph (70 km/h), climb and cross obstacles 3.28 ft (1 meter) high or wide, traverse side slopes greater than 40 percent, ford water to depths over 1.64 ft (0.5 meter) and overpass obstacles as high as 1.64 ft (0.5 meter) while compensating for varying payload weights and center-of-gravity locations. MULE will be transportable internally in a CH-47 Chinook or C-130 transports, and could be sling loaded under a UH-60 Black Hawk helicopter.

    The MULE includes three variants: Armed Robotic Vehicle – Assault (Light), Transport and Countermine. The assault version will be armed with rapid-fire suppressive weapon and anti-tank missile launchers. It is designed to provide immediate heavy firepower to dismounted troops. The Transport MULE will be configured to support the Future Force Soldier by providing the volume and payload capacity to carry the equipment and supplies to support two dismounted infantry squads. Multiple tie-down points and removable/foldable side railings support virtually any payload variation, including casualty evacuation. The Countermine variant is designed to detect and mark mines and minefields, greatly increasing the safety and mobility of the infantryman.
    Currently at an engineering evaluation phase, MULE is expected to mature into a full scale development system and be ready for deployment with the first FCS units of action, around 2013-1014. The company expects a requirement for 1,530 vehicles, based on current Army plans.

    Magnetically Operated NAno RotorCraft (MONARC)

    Draper Laboratory unveiled another concept for nano air vehicle – the Magnetically Operated NAno RotorCraft (MONARC). This miniature aerostructure uses a coaxial rotor powered by two direct drive brushless motors that run on new 2 gram lithium- ion battery developed at Massachusetts Institute of Technology (MIT) delivering power density of 250 Whr/kg.

    Actuation will be managed by magnetic virtual swash-plate with pitch amplification mechanism for directional control. The MONARC will use a unique control system, featuring a hybrid RF/Laser Radar (LIDAR) ‘tractor beam’ facilitating tele-operation and navigation indoor. It will use an avionics package weighing only two grams.

    Draper is currently working on a DARPA program, expected to complete by year’s end. DARPA’s required the vehicle to weigh less than 8 grams, fit into a sphere of 3 inches in diameter and carry a payload of two grams on a 20 minute mission. Mission profile indicated by DARPA includes 2 kilometers ingress/egress flight and 60 second hovering.

    MONARC will be able to sprint at up to five meters per second in the outdoors or fly autonomously on a controllable flight at a speed below 0.5 m/sec indoors. The current effort represents the first of a two phase program that seeks to develop and demonstrate an end-to-end system for hummingbird-scale UAV that executes ISR missions in denied battlespace. Another company participating in the DARPA NAV program is Lockheed Martin, which is designing a maple-seed like aerostructure for the NAV.
