When employed in constellations of coordinated and interconnected multiple vehicles, UAVs offer much improved efficiency compared to current systems concept of operation. Multiple tasks can be dynamically allocated between the constellation’s platforms, assigning the most suitable sensor for every user and target; furthermore, several sensors can be harnessed to focus on a single, high priority target, ensuring continuous coverage under all visibility conditions, viewing the target from different angles and altitudes. The constellation also offers inherent redundancy, automatically arranging to back-up any sensor which fails, due to logistical (return to base), technical or operational circumstances (shot down). Such constellations are even more critical for weapons employment, since the position of each weapon carrying platform can be dynamically computed to ensure that any ‘time critical target’ within the area under surveillance could be engaged within the required response time by one or more weapons.

Other area domination concepts, currently under development consider the deployment of persistent constellations of network-centric intelligent munitions. Each micro-platform will be fitted with a weapon datalink, feeding real-time video and Laser Detection and Ranging (LADAR) imagery, area surveillance and targeting and real-time Battle Damage Assessment (BDA) from the battlefield, over the Global Information Grid (GIG) to forward command and control centers. Unlike LOCAAS, these vehicles will be designed for multi-kill capability, and operate over open area as well as urban environment. Further evolved systems expected to be fielded toward 2030 will be optimized as layered systems, offering Total Urban Dominance Layered Systems (TUDLS) integrating various systems operating at different altitudes to dominate the vertical dimension denying enemy operations in all environments. These systems will be equipped with compact, directional and focused lethality warheads, featuring variable yield and advanced energetics, with sensors capable of locating camouflaged targets in cluttered terrain (urban) reducing collateral damage and minimizing risk to friendly forces.

Persistent UAV constellation currently evaluated by the US Air Force is developed by Boeing, using low-cost expendable system called Dominator. It is designed for deployment from stealth bombers and fighters (such as the B2 or F-22), at the starting phase of a conflict, to dominate key battlefield areas with persistent unmanned, highly autonomous yet fully controllable constellation of aerial sensors, weapons and support elements.

The system will provide the air force with persistent battlefield presence, maintaining offensive capability against time sensitive targets and mobile targets in more immediate form. It enables target tracking and requires ‘permission to attack’ in an accelerated fashion. The program is evaluating various options for carriage, and fast aerial release of Dominators. The first flight of the Persistent Munition Technology Demonstrator (PMTD), a testbed for future unmanned air-domination vehicles was made in April 2006. The 60 pound vehicle has a wingspan of 12 feet was used to demonstrate the autonomous flight capabilities. Future tests will include sensor integration and enhanced weapon terminal guidance demonstrations as well as possible in-flight refueling and munitions dispensing.

The theory of aerial dominating weapons is not new, but sofar its implementation remained limited by current technology to few, specific contingencies, such as the Suppression of Enemy Air Defense (SEAD), where targets could be clearly identified and pursued with radar homing weapons. Israel pioneered this field with the Harpy loitering SEAD weapon, developed by Israel Aerospace Industries. The system has been acquired by several countries including China, Turkey, South Korea and India. IMI is demonstrating a similar multipurpose warhead for their Delilah air launched missile, yet this weapon is quite large for conventional UAVs. A follow-on to Harpy, known as Cutlass was developed under a US-Israeli cooperation. While the program has not been officially concluded, Israel is known to have offered advanced Harpy systems to several customers, including the UK, where it was proposed as “White Hawk”, for the British Loitering Munition Capability Demonstration (LMCD) under cooperation with MBDA. Another Israeli company – RAFAEL – competed for the same program, offering the BLADE (Battlefield Loitering Artillery Direct Effect), based on a modified Sparrow M UAV designed and produced by EMIT.

A different concept, developed for the US Army pursued area domination, by a combination of several types loitering Non-Line-of-Sight (NLOS) missiles. The original concept included ‘smart’ loitering weapons, which would provide area surveillance, target acquisition and pursuit of time critical attack, while other targets would be engaged by precision attack missiles (PAM), fitted with imaging infrared seekers. But this concept proved too costly and complex. The Army eliminated the loitering missile-sensor element, deploying the NLOS launch system with the PAM, provided as a weapon repository ready to support combat units, targeted by assets available to the unit over the network.

Various types of air domination systems are considered by the US Air Force, enabling a military force to dominate an area from the air for extended periods, denying enemy movements and maneuvering. Current systems considered for these tasks are standard weaponized UAVs, or small expendable loitering weapons, fitted with imaging sensors, such as the powered Low Cost Autonomous Attack System (LOCAAS). Operating in swarms of ‘intelligent munitions’ weapons, such as the LOCAAS can autonomously search for and destroy, aiming for critical mobile targets over a wide combat area. Recent enhancements of the LOCAAS concept introduced ‘man in the loop’ functionality enabling re-targeting as well as the ability to abort attack by a human controller when required. Further enhancements could integrate the LOCAAS into a Surveilling Miniature Attack Cruise Missile (SMACM) ‘mothership’ carrying four LOCAAS units. The mothership will be able to support thee units with targeting, surveillance and communications support, extending the range and persistence of the basic version beyond 250 nautical miles. LOCAAS and SMACM are designed to operate in open area, pursuing stationary and mobile targets of opportunities as soon as the are exposed in the open.

Unlike laser guided munitions, which share a mutual electro-optical signal to coordinate the sensor and shooter, GPS guided weapons require precise target coordinated, which must be extracted through manual process, from aerial photos, maps and other sources, verified for accuracy, to eliminate potential collateral damage or risk to friendly forces. Such process is prone to calculation errors which could cost human lives. A computerized process which will transform live imagery into geospatial coordinates, interpreted by ‘coordinate seeking weapons’ (GPS guided, such as JDAM), could have a dramatic effect on the way such weapons are used, especially under limited visibility conditions, when the use of laser guided weapons is limited. Current ‘sensor to shooter’ systems are designed to pursue time critical targets within 10 minutes from detection, as semi-automatic processes enable to prioritize the most critical imagery, assisting target extraction and communications to the platform, enabling target prosecution within 3 minutes or less from detection.

This cycle requires the targeting process to operate in near-real-time rates, lasting less then three minutes. However, typical target life in asymmetric warfare is much shorter than that. One of the systems playing a key role in improving those rates is the Currently an Advanced Concept Technology Demonstration (ACTD) development Gridlock will provide position data, accurate to within 10 meters and shorten the time elapsing from sensor detection to weapon launch, to less than sixty seconds. Gridlock replaces current time-consuming manual imagery registration with an automated machine-to-machine process, embedding geopositioning data in each pixel. The system will transmit actionable information to a display in the field showing accurate coordinates and error estimates, by moving a cursor over the image of interest. Gridlock will then export selected coordinates into targeting tools. This technique will minimize the need for training and improve sensor-to-shooter response time.

Gridlock focuses on three ISR platforms used by the Air Force: the Predator, Global Hawk and the piloted U-2. The Air Force is expected to transition the technology to operational systems following conclusion development and demonstrations conducted through 2006.

Facing similar issues, the Israelis have pursued such solutions for heir targeting tasks. Few years ago, RAFAEL unveiled the Golden-Bay real-time imagery processing system. The system provides real-time, high throughput and high accuracy processing of reconnaissance imagery, yielding a dramatic increase in accurate target generation rate. The original system was housed in a field deployable shelter, yet keeping pace with computing technology, it can now be positioned much closer to the ‘sensor to shooter’ cycle, embedded into smaller processors and payload control systems, pursuing faster Time Critical Targeting paces.

The introduction of remote video links, enabling operators to monitor the UAV’s payload view in real time, enables users to employ weaponized UAVs more flexibly and with improved confidence. Network enabled systems employing distributed command and control elements, with Intelligence, Surveillance and Reconnaissance (ISR) and armed airborne assets (either separate platforms or integrated into a single unit) benefit from progress made with UAVs and precision guided weapons. Typical weapons which could be adapted for UAV use include the Israeli LAHAT, designed by IAI subsidiary MBT to meet requirements of the Israeli armored corps. As early as 2004 this weapon was proposed for testing with US Hunter UAVs. Lahat utilizes the semi-active laser homing guidance method to accurately home in on targets from a distance beyond 10 km. Fitted with a shaped charge multi-purpose warhead, LAHAT can engage targets marked by laser designator mounted on the launching platform or by an indirect designation, from another unit located closer to the target. Each missile weighs about 13 kg and a complete launcher, with the four missiles weighs only 75kg, significantly less than any alternative weapon. The laser Guided SPIKE was developed by the Weapons Division of the Naval Air Warfare Center, US Navy, with assistance of DRS Technologies. Originally designed as a man-portable weapon for the Marines and the Navy’s special operations force, Spike fills a critical niche for a low-cost, lightweight guided weapon for U.S. ground forces. It is also considered for tactical unmanned aerial vehicles and a force-protection weapon to defend surface ships from small-boat swarms or light aircraft. The missile uses Semi-Active Laser (SAL) seeker to engage laser designated targets from a distance of two miles. Each Spike missile weighs 5.3 lb (2.5 kg) and is 25 in. ( cm) long. The missile performed its first controlled flights in 2005. Spike missile is designed to be used on medium and lightweight UAVs. The missile has already been tested with the DRS Sentry HP drone at Eglin AFB, Florida, as part of US Air Force UAV Battlelab evaluation.

Another type of lightweight weapon considered for UAVs is the 2.75″ Hydra 70 rocket. In 2005, four 2.75-inch rockets were fired from Vigilante Unmanned Aerial Vehicle (UAV) testbed, demonstrating the weaponization potential of rotary wing UAVs. The tests evaluated the stability and flight control flight control adjustments necessary to compensate for excessive loads during the weapon’s firing. On these tests the Vigilante was controlled from a nearby UH-1 manned helicopter. Such tests will provide important data for the integration of Advanced Precision Kill Weapon System (APKWS II) with future rotary wing UAVs. APKWS II is intended to fill an aviation systems weapons gap between the Hellfire Missile and Unguided Hydra-70 2.75-Inch Rocket, introducing an affordable, lightweight, precision aerial guided rocket APKWS II weighs about 13 kg, integrating strap-down laser seeker (fixed in the wing roots) and guidance section onto the Hydra-70 Rocket, it will be effective against soft and lightly armored targets as well as urban operations. In April 2006 BAE Systems was contracted for the two year $45.7M system design and development phase, teamed with Northrop Grumman and General Dynamics. Production is expected to begin in 2008. The new design uses existing or new production rockets, fitted with a mid-body guidance approach that employs BAE Systems’ Distributed Aperture Semi-Active Laser Seeker (DASALS), the same element is also used in the Army’s Precision Guided Mortar Munitions Program. APKWS II will utilize the Hydra Universal Rail Launcher (HURL), a lightweight four-rail launcher originally developed for the Comanche attack helicopter but modified for use with UAVs. Designed as a ‘smart rocket launcher’, HURL can be linked to on-board avionics through Mil-Std-1760 and Mil-Std-1553 interfaces. Lockheed Martin also developed a version of 2.75″ laser guided rocket called Direct Attack Guided Rocket (DAGR) designed to be fully compatible with the Hellfire II system and 229 smart launcher system, therefore increasing the launcher load-out by up to four times. The rocket was flight tested in February 2007 and is expected to complete testing in 2007. The Russian company Basalt is offering the TBG-29 rocket propelled weapon, loaded with thermobaric warhead, to equip light aircraft and UAVs operating in close support operations. The weapon is designed to annihilate troops on open terrain, in trenches, field shelters, and inside buildings and destroy lightly armored and soft skinned targets. The round is fired from grenade launchers (RPG-29 and RPG-29N). Aircraft, helicopters or UAVs with a maximum takeoff weight of 1,000 kg or higher which can also carry the multiple launch rocket systems loading up to 7 rockets each. The 105mm diameter rocket measures 695mm in length, and weighs 6.7 kg. It can be fired at targets ranging from 50 to 2,000 meters. In enclosures, the thermobaric charge is effective within a volume of 300 square meters or at a radius of 10 meters from the detonation point, in open terrain. When fired near windows gun-ports etc, the detonation will kill any person within one meter from the detonation point or two meters, when fired at troops in trenches. Switchblade is another weapon, developed by AeroVironment, Inc. It is designed for hand, tube or aerial launch, and could provide the warfighter with a “magic bullet” delivering ‘instant’ Intelligence, Surveillance and Reconnaissance (ISR) on Beyond Line-of-Sight (BLOS) targets within minutes. Designed as an expendable system, Switchblade will also have an option to carry a small explosive charge to enable rapid prosecution of selected targets. The miniature, remotely-piloted or autonomous platform can either glide or propel itself via quiet, electric propulsion, providing real-time video for information gathering, targeting, or feature/object recognition.

The first weaponized UAVs were armed with standard munitions, meeting payload weight restrictions of existing unmanned vehicles. At that time, the Lockheed Martin Hellfire II missile was found to be the most suitable weapon for such roles. However, in a parallel path, the US Air Force and Army have been evaluating other weapons, including the Northrop Grumman BAT munition and its derivatives, as well as other types. Among the weapons considered for testing were two Israeli weapons, the IAI/MBT Lahat laser guided missiles, and RAFAEL Spike LR electro-optical guided missiles, both are believed to have been deployed with UAVs.

In the past, standard missiles and gravity dropped weapons were found inadequate for employment with UAVs. For example, the Hellfire, designed for launching from manned platforms, did not have adequate off-boresight flexibility to acquire unexpected target,s therefore limiting engagement profiles and increasing the potential for collateral damage. Launch signature and range have limited its suitability for surprise attacks. The stealthy, acoustically guided BAT proved useless for low intensity warfare, since typical target acoustics can hardly be defined in adequate resolution for an attack. The weapon was therefore modified with a new semi-active laser homing device. Designated Viper-Strike, it retained the Bat’s vertical dive capability, demonstrating excellent precision kill while reducing collateral damage. Few of these weapons are currently deployed in Iraq, flying on Hunter UAVs. Northrop Grumman is reportedly making efforts to reduce the weight of the Viper Strike to 11.3 kg, thus making it suitable for the 168 kg AAI RQ-7B Shadow 200. The new AGM-114P Hellfire version has already been optimized for the Predator UAV. Among the modifications are increased weapon engagement zone (WEZ), enabling the seeker to acquire targets off-boresight up to 90 degrees to each side. These missiles can be released from higher altitude (10,000 to 25,000 ft), eliminating the need to descend to lower altitude prior to weapon release. The AGM-114P was cleared for service in early 2005.

RAFAEL’s family of electro-optically guided missile, known as the Electro-Optically guided Spike is also proposed for weaponized UAV applications. It was publicly unveiled on UAVs when proposed by Sagem to arm their Sperwer B UAV for demonstrations for the French military. The French study required the UAV to be capable of delivering high terminal precision, especially in asymmetric conflicts, and maintain the controller in the loop from launch to impact in order to minimize operating risks. Two versions of Spike are proposed for airborne applications – the Spike LR, and extended range version (Spike ER), which can be fitted with blast-penetration warhead, designed to inflict maximum lethality inside buildings or vehicles but minimize collateral damage to the surrounding area. Utilizing a fiber-optical link, Spike offers unique fire and forget or fire-observe and update operating modes either autonomous guidance or maintaining a “man in the loop” option throughout the missile’s flight, as the missile relays the scene viewed by it’s seeker, enabling the controller to accurately select the point of impact or abort the mission when the conditions are not matching the rules of engagement (for example, presence of civilians). IMI is also working on reduced lethality warheads, designed to optimize the terminal effect against buildings, vehicles and other soft targets, characteristic of urban environment.

A similar trend is taking place in Europe. MBDA is developing a technology demonstrator, proposed as a follow-on to the HOT system, currently known as the Missile de Combat Terrestre (MCT), which could be utilized in the future for armed UAVs. The new missile will be able to engage targets at Non-Line Of Sight (NLOS) mode, where the missile’s seeker does not have to be aimed at the target before launch. The company is developing several variants for the missile, including medium and long range versions with range of up to 8 km and turbo-jet powered extended range versions, with a maximum range of 100km. The weapon considered for the missile will include “multi-effect” warhead, making it effective against a broad target set, including fortified constructions, bunkers, armored vehicles and soft targets. The warhead could be equipped with a programmable lethality package to create “scalable” effect, tailored for specific operating scenarios.

In recent years, weaponized UAVs have been used primarily by US forces as part of the global war on terror (GWOT). Predators were employed to support Special Forces operating over mountainous area in Afghanistan and Northern Iraq. Predators launched their Hellfired into a “basket”, where the missiles could lock on the target, illuminated by laser designators operated by Special Forces teams which roamed the area, tracking their targets on the ground, waiting for an opportunity to launch an attack. These teams could also benefit from imagery transmitted from the UAVs, patrolling the area at high altitude.

Evolving concepts of operation call for the simultaneous and coordinated operation of multiple UAVs, operated partly autonomously, while mutually supporting each other with ISR and weapons coverage. Such constellations of UAVs are providing warfighters with rapid response when engaging time critical targets (TCT) at reduced rate of response between target detection, targeting and engagement.
More covertly, such platforms were reportedly employed by the Israelis throughout their recent conflict with the Palestinians, performing many ‘targeted killings’, on terrorists as they were spotted by Israeli intelligence, moving openly in the streets of the Gaza strip. The types of weapons used by the Israeli UAVs have not been disclosed, but according to Palestinian reports, a gradual evolution of weapons has been encountered during the years since the beginning of the Intifada in 2000. In recent years, the damages inflicted by the Israeli aerial launched weapons became more focused, more lethal, indicating of smaller, accurate weapons, designed to minimize collateral damage while enabling accurate and effective engagement of mobile targets in complex urban environment. According to foreign sources, various constellations of weaponized UAV swarms were employed over South Lebanon during the 2nd Lebanon War in the summer of 2006, in effort to hunt Hezbollah rocket launchers scattered in hidden lairs around this area.

MQ-1B, the Armed configuration of the General Atomics Predator UAV operated by the US Air Force is now standard configuration for this unmanned aircraft, flown on routine missions from Balad air force base in Iraq. This UAV differs from the original Predator by the installation of two hard points carrying Hellfire missile launchers. These weapons are routinely used on armed reconnaissance missions. Another version of the Predator known as Warrior is currently under development for the US Army Extended Range / Multi Purpose (ER/MP) program. This aircraft will be fitted with four external carriage hardpoints loading four Hellfire missiles. The Army also considers adapting the Northrop Grumman Viper Strike and a unified dispenser which can carry various gravity dropped weapons, as well as supplies to support Special Forces deep inside enemy territory.

The USAF unmanned fleet will soon be augmented by a larger, more advanced system known as the Reaper MQ-9A. This UAV was designed from the beginning as a “Hunter-Killer” system. Compared with the limited strike capability of current UAVs flying at altitudes of 15,000-25,000 ft, the Reaper will be able to loiter at an altitude of up to 50,000 feet over a mission area, for up to 30 hours, armed with some 16 Hellfire II missiles or enhanced capability, with combination of Hellfires and precision guided bombs, such as GBU-38 JDAM or GBU-12 laser guided bombs (500lbs each). The aircraft will have a maximum gross takeoff weight of 10,000 pounds ( 5 Tons)s. It will be powered by a turbo-prop engine and have a wider fuselage, storing the fuel and payloads necessary for extended missions. Weapon guidance techniques can also utilize advanced parafoil decelerators, such as the Micro Onyx, which canguide a warhead to a hit a precise target, marked by GPS coordinates. The manufacturer claims this concept is more effective, lighter and costs less than conventional aerial guided weapons. Similar systems are already used within the Steel Eagle program, for the emplacement of aerial delivered unattended ground sensors (UGS).

The US Air Force has requested funding of about $825 million for 74 Predators over the next six years, augmenting the 68 now in service. Thirty-two of those would be MQ-9 Reapers. In total, 15 squadrons will be operational. The USAF is currently testing more weapons with Predator and eventually Reaper, including the Viper Strike laser guided munition, small diameter bomb, laser guided munitions and Stinger air/air missile. Employment of air-to-air weapons like Raytheon’s AIM-9 Sidewinder and AIM-120 Advanced Medium-Range Air-to-Air Missile may also be evaluated at some point. Other weapons could include the PASSM, a more accurate and versatile precision attack missile proposed as a future alternative for the air-launched Hellfire II.

During the recent conflict in Lebanon and the ongoing conflict between Israel and the Palestinians, the IDF was reported to be using armed UAVs for attacking suspected terrorists in the West Bank and Gaza. The type of platforms or weapons used are classified, but according to industry briefings, several Israeli companies are involved in the development and fielding of lightweight, precision strike weapons and warheads designed specifically for operation in urban environments.

Officially, Unmanned Combat Aerial Vehicles (UCAV) are still in early development, but such systems have already become important players in modern combat operations, primarily by US and Israeli forces operating in Low Intensive Warfare in the Middle East and Afghanistan. Other countries, including several NATO members, are also pursuing such capabilities.

UAVs were first used in significant numbers during the Vietnam War, and later, in the Israeli invasion of Lebanon in 1982, but these were primarily reconnaissance platforms. The first lethal applications of UAVs were considered as “suicide missions”, utilizing the slow flying unmanned aircraft as precision guided ‘flying bombs’, which could loiter over enemy area for extended periods of time, in search of active radars or guided missile sites. During the late 1980s the first radar killer drone known as Harpy was developed under cooperation between IAI and Diehl, in a parallel program, another loitering weapon – the air-launched Delilah missile was developed in Israel by IMI. Few years later another, rather unique concept of combat drone was considered by the Israel Ministry of defense, during the early 1990s, immediately after the first Gulf war, when Israel was seeking a solution to counter the threat of ballistic missiles.

One such concept was the MOAB Boost-Phase Interceptor (BPI), which would have utilized a boosted version of the Python 3 air-to-air missile, launched by an unspecified stealthy High Altitude Long Endurance (HALE) UAVs operating deep over enemy territory. While Moab never reached even demonstration stage, Israel has not abandoned this concept and, according to foreign sources, deployed a full scale UAV centric BPLI system for the first time during the 2006 Lebanon war, in an attempt to hunt medium range rocket launchers used by the Hezbollah to attack targets in Israel. While the system did not succeed in eliminating the illusive short range rockets, the effectiveness, life span, and survivability of long and medium range rockets launchers was dramatically reduced as the war progressed.

The concept of an armed UAV was publicly outlined in 1996, as the US Air Force Chief of Staff directed the study “UAV Technologies and Combat Operations”, recommending testing and developing weaponized versions of high flying UAV, particularly for Supression of Enemy Air Defense (SEAD) operations. During allied operations in Kosovo, UAVs were supporting strike packages to locate time-critical targets. Such targets were identified and confirmed using the TV payloads carried by General Atomics RQ-1 Predator UAVs.

However, targets frequently eluded the aerial strikes, due to the delay between the target detection, attack preparation process (targeting) and the actual execution of the attack. Essential improvements applied on UAVs just after the operation in Kosovo included the integration of laser designator in the standard EO/IR UAV payload. Work on a weaponized version of the Predator commenced, culminating in a series of test firings of Lockheed martin Hellfire missiles from USAF Predator UAVs in 2001. These platforms were later flown by the CIA and already demonstrated dramatic results during operations in Iraq, Afghanistan and Yemen. CIA operated Predators were credited with the elimination of senior Al-Qaeda operatives and Taliban fighters in 2002. Another example for an early generation armed UAVs is the Nothrop Grumman / IAI MQ-5A Hunter, an armed derivative of the RQ-5A UAV. This aircraft was also fitted with an extended wing, carrying hard-points for two weapons such as Hellfire or Northrop Grumman Viper-Strike munitions. The General Atomics Gnat UAV is also designed to carry Hellfire missiles.

Sikorsky’s X2 Technology demonstrator conducted a successful ground test in November 2006. The X2 Demonstrator is scheduled to take flight in 2007. Jeffery Pino Sikorsky Aircraft President considers this new technology is one the major pillars for the company’s future growth.

He also noted that Sikorsky’s recent announcements regarding strategic business relationships in the Mid-east, Europe, and Asia underscore its objective of bolstering its leadership position in the global aerospace market. “Thanks to the support of our customers worldwide, we are on track to double our revenues for the 2003 – 2008 timeframe, and given the projected strength in the military, commercial, and service and support markets, we expect this growth to continue. The number of products we have in production has grown from just three in 2000 to 10 today, with another six active development programs in work. Sikorsky Aircraft, a subsidiary of United Technologies Corp. (NYSE:UTX), had $3.2 billion in revenues in 2006.

Sikorsky’s X2 refers to an integrated suite of technologies that improve the performance of coaxial helicopters, resulting in a new generation of helicopters that will be able to fly at up to twice the speed of current helicopters, while retaining all the desirable flying qualities of a helicopter at low speed, without any in-flight configuration transition. This suite of technologies includes advanced blade technologies to significantly increase lift without increasing drag, fly by wire, active vibration control, advanced hub drag reduction, and an integrated propulsion system that intelligently controls the power shared by the aft propulsor and the main rotor. The main X shaped coaxial rotor will be slowed during high speed flight to keep the rotor tips below supersonic speeds.

X2 Technology can also be applied to conventional speed coaxial helicopters without auxiliary propulsion, enabling even greater lift and hover efficiency.

FLY-K weapon system is a lightweight 52mm indirect fire weapon system designed to fire 52mm mortar bombs from a quiet, low-signature launcher, at distances up to 800 meters. The multiple-launcher system can be used as a squad-support weapon, on mounted platforms or in dismounted and portable configuration.

Designed to support Special Operation Forces, FLY-K uses a closed combustion chamber to capture all propulsion gases, thus eliminating flash, smoke or heat emissions and produces low acoustic and visual signature (52dB at 100 meters). The FLY-K will not reveal its firing position, even at night. FLY-K can be launched from a hand-held single launcher or a 12 bomb launcher pack. A single HE round weighing 650 – 805 grams has a lethal radius of 16 meters, while a salvo of 12 rounds effectively covers an area 50 meters by 100 meters at maximum range. An FLY-K launcher with 20 rounds weighs less than 20 kg. The hand launcher weighs 4.5 kg, has a range of 750 meters and can fire up to 30 rounds per minute.
