How robot drones revolutionized the face of warfare

(CNN) -- Barely an hour's drive from the casinos of Las Vegas, a group of unassuming buildings have become as important as the trenches were to WWI. The big difference? Today's warriors are fighting without getting in harm's way, using drones to attack targets in Afghanistan and Pakistan.
Remote-controlled drones, such as the Predator, are proving increasingly popular with the U.S. military.

Remote-controlled drones, such as the Predator, are proving increasingly popular with the U.S. military.

U.S. Air Force fighter pilot Major Morgan Andrews is one such combatant. He kisses his wife goodbye, drives to Creech, a tiny desert air force base in Nevada, and within minutes could be killing insurgents on the other side of the world.

Andrews fights not from the seat of the F16 he joined the air force to fly but from a darkened ground control station. He pilots a remote-controlled Predator, a UAV (unmanned aerial vehicle) which can spy on and attack positions and personnel without risk to its controller, shooting deadly Hellfire missiles at enemy fighters in support of fellow soldiers.

"You're talking to them on the radios as if we were in a normal airplane flying overhead," says Andrews. "You see the imagery, you know what's going on, you see what you're looking at. It's very easy when something like that is happening to project yourself there and feel a part of the battle. Like I said, your heart starts racing a little bit." Is remote-controlled warfare a good or a bad idea? Tell us what you think.

Meanwhile intelligence analysts get to see images in real time and can identify personnel on the ground.

There are now more than 7,000 UAVs ranging from the workhorse, the Predator, and its beefier, deadlier kin the Reaper, to army drones like the tiny hand-launched Raven and the larger Shadow.

The drones are dramatically tilting the war in favor of the United States. Predators, for example, played a key role in killing al Qaeda in Iraq leader Abu Musab al Zarqawi in 2006. UAVs are credited with killing more than half al-Qaeda's top 20 leaders.

Now U.S. Secretary of Defense Robert Gates wants more UAVs. Already he has said that the next generation of fighter planes -- the F-35 that took decades to develop at a cost of more than half-a-billion dollars each -- will be the last manned fighter aircraft.

Lt. Gen. David Deptula, USAF, explains that the next phase will enable a single drone to provide as many as 60 simultaneous live video feeds direct to combat troops. Some new drones will be as small as flies, others walk -- all appear destined to work with decreasing human input.

"The future of how you use these un-manned systems or remotely piloted systems is really unlimited," says Deptula, based at the Pentagon and racing to keep pace with battlefield needs as well as Gates's demands. "We need to open our minds and think more about capability and impact we are going to achieve as opposed to how we've done business in the past." Video Watch how UAVs are changing the face of warfare »

At Creech frontline requests surged when weapons were first put on the Predator. In Iraq and Afghanistan drones have become so indispensable that missions are cancelled if they are not available

Robotic warfare expert Peter Singer, who advised President Barack Obama's campaign team and has authored "Wired for War," says that remote warfare is changing mankind's monopoly on how conflict is fought for the first time in 5,000 years. All that limits its advance is its application, not the technology.

"The barriers of war in our society are already lowering," he says. "This tech may allow them to lower to the ground. And we might already be seeing this in the strikes being carried out on Pakistan."

He points out that raw numbers over the last year show the same number of strikes as the opening of the Kosovo war. "But we didn't debate about it in Congress, we don't talk about it daily in our media."

Pakistani officials say drones are killing al Qaeda leaders who thought they were beyond U.S. reach. But even the U.S. government admits civilians are dying in those attacks too.

Singer fears the use of drones is misunderstood as cowardice, undermining the effectiveness of attacks and ultimately losing the war UAVs are fighting.

He explains that last year one of the most popular songs in the Pakistani charts talked about America fighting without honor, adding that the U.S. is "getting better and better at targeting leaders but perhaps creating a context that gets more recruits."

The spokesman for Taliban leader Mullah Omar recently told me that it is not afraid of drones, that it doesn't fear death. Deptula disagrees and quotes recently declassified comments between two Taliban leaders: "Tanks and armor are not a big deal, the planes are the killers."

He says that of more than 600 Hellfires fired by Predators, over 95 percent exactly hit their targets. Those that failed did so generally through mechanical fault, loss of guidance or a target moving at the last instant, Deptula says.

Singer cites other instances when a computer fault has turned robotic warfare into a mass casualty event. "Last year in South Africa an anti-aircraft had a 'software glitch' during a training exercise," he says. "It was supposed to fire upwards into the sky, instead it lowered and it fired in a circle and killed nine soldiers, all because of a software glitch."

For the U.S. military the gains more obviously outweigh the glitches. Hundreds, possibly thousands, of service men and women have had limbs and lives saved by bomb-detecting bots. Conservative estimates say that fighting from home and putting robots in to war has saved hundreds of millions of dollars.

At Creech the demand for Predator pilots is so intense that it is mobilizing Air National Guard and reservists. It has also introduced an experimental training program for air force cadets from the videogame generation.

Colonel Chris Chambliss, based at Creech, explains: "If you look at younger people right now, they multitask much better than I do. They can do a lot of things with a lot of different information, gather all that in. That's certainly a skill set we need."

Cadet Greg Groves, who is in the Reserve Officers' Training Corps, has never flown a plane before -- but is well aware of his responsibilities.

He says: "It's pretty clear that it's not a video game, and it is real life and that what I do directly affects someone else halfway around the world. So I don't think that's going to be a big problem for me."

Groves' father and grandfather were both in the military: when he leaves for Creech he'll be the first in his family to go to war without fear of dying.

Some commanders, such as Colonel Baxter Swift, based at USAF Balad in Iraq, says the future has only just begun.

He says: "It's almost like what the hot air balloon was back in the Civil War for us. 'Hey, I can rise above and look around and see what the forces are doing on the battlefield.' So now we are just in the pioneering stage."

Yet if U.S. forces can have UAVs, so can other nations. An estimated 40 or more countries also developing drones, with an Iranian UAV already shot down over Iraq a few months ago. Even Hezbollah -- a political movement, not a state --- has used them against Israel. Video Watch how the demand for UAVs has increased »

For his part, Singer draws another historical parallel, comparing the U.S and the UAV to the British invention of the tank in the early 20th century.

"There is no such thing as a permanent first maneuver advantage," Singer says.

"The British came out of WWI with the most tanks, they invented the tank and yet they didn't figure out the best way to use it in the wars they would be fighting. It was the Germans that figured that out and it was the Germans that would be fighting and would win with the tank when WWII starts."

MQ-8 Fire Scout

The Northrop Grumman MQ-8 Fire Scout is an unmanned autonomous helicopter developed for use by the United States armed forces. Northrop Grumman is developing the Fire Scout to provide reconnaissance, situational awareness, and precision targeting support. The initial RQ-8A version was based on the Schweizer 330, while the enhanced MQ-8B is derived from the Schweizer 333.

Design and development RQ-8A

As the US Navy was withdrawing its RQ-2 Pioneers from service, it began to seek a second generation UAV. The Navy requirement specified a vertical takeoff & landing (VTOL) aircraft, with a payload capacity of 90 kilograms (200 pounds), a range of 200 kilometers (125 miles), an endurance on station of three hours at an altitude of 6 kilometers (20,000 ft), and the ability land on a ship in a 46 km/h (29 mph) breeze. The UAV was to fly 190 hours between maintenance.

There were three finalists in the competition, which was designated "VTOL-UAV" or "VTUAV". Bell, Sikorsky, and a collaboration of Teledyne Ryan and Schweizer Aircraft submitted designs. The Ryan-Schweizer UAV was selected as the winner in the spring of 2000. The RQ-8A Fire Scout, as it was named, was a derivative of the Schweizer three-passenger, turbine powered 330SP helicopter, with a new fuselage, new fuel system, and UAV electronics and sensors.

The initial prototype of the Fire Scout was piloted in initial tests, flying autonomously for the first time in January 2000. The Rolls-Royce 250-C20 turbine engine ran on JP-5 and JP-8 jet fuel, which is nonvolatile and safe for shipboard storage.

The Fire Scout was to be fitted with a sensor ball turret that carries electro-optic and infrared cameras, and a laser range finder. It was to be controlled over a data link derived from the Northrop Grumman RQ-4 Global Hawk UAV, operating over a line of sight to a distance of 280 kilometers (172 miles). The control system was to be fitted onto a ship, or could be carried on a Hummer light vehicle for U.S. Marine service.

In January 2006, an RQ-8A Fire Scout landed aboard the U.S. Navy warship USS Nashville while it was steaming off the coast of Maryland near the Patuxent River. This marked the first time an unmanned helicopter has landed aboard a moving U.S. Navy ship without a pilot controlling the aircraft. The USS Nashville, which is an amphibious transport ship, was maneuvering as fast as 17 mph (27 km/h) in the tests.

MQ-8B

Although progress on the project had been regarded as satisfactory, the Navy decided the Fire Scout didn't meet their needs after all, and cut funding for production in December 2001. However, the development program continued, and Northrop Grumman pitched a range of improved configurations to anyone who was interested. As it turned out, the U.S. Army was very interested, awarding a contract for seven improved "RQ-8B" evaluation machines in late 2003. In 2006, it was redesignated "MQ-8B".

The MQ-8B features four-blade main rotor, in contrast to the larger-diameter three-blade rotor of the RQ-8A, to reduce noise and improve lift capacity and performance. The four-blade rotor had already been evaluated on Fire Scout prototypes. They boost gross takeoff weight by 500 pounds to 3,150 pounds (by 225 kg to 1,430 kg), with payloads of up to 700 pounds (320 kg) for short-range missions.

The MQ-8B is fitted with stub wings as well. The wings will serve both an aerodynamic purpose as well as an armament carriage location, to include weapons such as Hellfire missiles, Viper Strike laser-guided glide weapons, and in particular pods carrying the "Advanced Precision Kill Weapon System (APKWS)", a laser-guided 70 millimeter (2.75 inch) folding-fin rocket, which the Army sees as ideal for the modern battlefield. The Army is also interested in using the Fire Scout to carry up to 200 pounds (90 kilograms) of emergency supplies to troops in the field.

The MQ-8B is being modified to permit rapid swapout of payload configurations. The current sensor configuration of a day/night turret with a laser target designator will of course remain an option. Alternate sensor payloads in consideration include a TSAR with Moving Target Indicator (MTI) capability, a multispectral sensor, a SIGINT module, the Target Acquisition Minefield Detection System (ASTAMIDS), and the Tactical Common Data Link (TCDL). The Army wants the Fire Scout to operate as an element of an integrated ground sensor network as well.

The Army interest revived Navy interest in the program, with the Navy ordering eight Sea Scout MQ-8B derivatives for evaluation.

Operational history

Production of the flight test airframes was initiated in April 2006 at the Northrop Grumman Unmanned Systems production plant in Moss Point, Mississippi. First flight of the MQ-8B took place on December 18, 2006 at NAS Patuxent River.

The flight test program is underway and the Navy approved low-rate initial production.Production aircraft will eventually be deployed on the Navy's Littoral Combat Ships.

In February 2008, the U.S. Navy announced that they would integrate the MQ-8B Fire Scout VTUAV onto another air-capable ship before it reaches the Littoral Combat Ship (LCS).[citation needed] The Fire Scout is still slated to go aboard the LCS, and the Navy remains committed to transitioning the Fire Scout in that direction.

The Fire Scout is a key enabler for LCS and significantly contributes to its designated warfare mission areas of anti-submarine warfare, surface warfare and mine warfare. The modular nature of the ship to accomplish the designated mission is complemented by the Fire Scout and its modular mission payload capability. However, due to changes in the LCS development schedule, the Navy intends to conduct the Fire Scout Operational Evaluation (OpEval) aboard USS McInerney (FFG-8).This will provide the fleet with unmanned aerial system support as soon as possible.

The Fire Scout first embarked aboard the guided-missile frigate USS McInerney, an Oliver Hazard Perry-class frigate, while in port for operational fit checks and ship integration testing on Dec. 10, 2008. The Fire Scout is slated to deploy aboard USS McInerney during its next counter-narcotics trafficking deployment later this year.

According to the current schedule, the Navy will conduct Technical Evaluation on the Fire Scout on the FFG-8 in the fall 2008 and OpEval in the summer 2009. The Fire Scout will reach Initial Operating Capability soon after OpEval in 2009. The Navy will continue to support LCS Initial Operational Test and Evaluation (IOT&E) efforts in fiscal year 2011.

Recent flight tests took place May 4-8 off the coast of Mayport, Fla. The U.S. Navy Fire Scout completed test flights in areas of shipboard deck motion and wind envelope expansion and landings including the use of the grid and harpoon system. During the five days of testing, the ship/aircraft team compiled 19 flight hours during 12 flights, which included 54 landings, 37 of which were into the NATO standard grid.

Heron

The Heron or Machatz-1 is an Unmanned Aerial Vehicle developed by the Malat (UAV) division of Israel Aerospace Industries. It is capable of Medium Altitude Long Endurance (MALE) operations of up to 52 hours' duration at up to 35,000 feet. It has demonstrated 52 hours of continuous flight, but the effective operational maximal flight duration is less, due to payload and flight profile. There is a new version, Heron TP, also known as Eitan (UCAV).

On September 11, 2005 it was announced that the Israel Defence Forces purchased US$50 million worth of Heron systems. The IDF's designation of the Heron is Machatz-1.

Navigation
Heron navigates using an internal GPS receiver, and either a pre-programmed flight profile (in which case the system is fully autonomous from takeoff to landing), manual override from a ground control station, or a combination of both. It can autonomously return to base and land in case of lost communication with the ground station. The system has fully automatic launch and recovery (ALR) and all-weather capabilities.

Payload

Heron can carry an array of sensors, including infra-red and visible-light surveillance, intelligence systems (COMINT and ELINT) and various radar systems, totaling up to 250 kg (551 lb). Heron is also capable of target acquisition and artillery adjustment.

The payload sensors communicate with the ground control station in real-time, using either direct line of sight data link, or via an airborne/satellite relay. Like the navigation system, the payload can also be used in either a fully pre-programmed autonomous mode, or manual real-time remote operation, or a combination of both.

Nishant

The DRDO Nishant is an Unmanned Aerial Vehicle (UAV) developed by India's ADE (Aeronautical Development Establishment) a branch of DRDO for the Indian Armed Forces. The Nishant UAV is primarily tasked with intelligence gathering over enemy territory and also for recce, surveillance, target designation, artillery fire correction, damage assessment, ELINT and SIGINT. The UAV has an Endurance of 4 hrs & 30min. Nishant has completed development Phase and User trials.

The 380 kg Nishant UAV requires rail-launching from a hydro-pneumatic launcher and recovered by a Parachute System. Launches at a velocity of 45 m/s are carried out in 0.6 seconds with 100 kW power and subsequent launches can be carried out in intervals of 20 minutes. The Mobile Hydro-Pneumatic Launcher (MHPL) system mounted on a Tatra truck weighs 14,000 kg and boasts of a life cycle of 1000 launches before requiring overhaul. Nishant is one of the few UAVs in the world in its weight-class capable of being catapult-launched and recovered by using parachute, thus eliminating the need for a runway as in case of conventional take-off and landing with wheels.

Development

To meet the Army’s operational requirement of an RPV it was decided in September 1988 that the Defence Research and Development Organisation would undertake the indigenous development of the UAV. The General Staff Qualitative Requirement (GSQR) was finalised by the Army in May 1990. The Nishant RPV made its first test flight in 1995. In July 1999, for the first time the Indian army deployed its new Nishant UAV system in the fight against guerilla forces backed by Pakistan in Kashmir. Nishant, which had been developed for battlefield surveillance and reconnaissance needs of the Indian Army, was test flown again in early 2002. The indigenous Unmanned Air Vehicle (UAV) Nishant developed by DRDO had completed its 100th flight by June 15 2005.The Indian Army has placed an order for 12 Nishant UAVs along with ground support systems.Nishant Unmanned Aerial Vehicle (UAV) developed by DRDO for Indian Army was successfully flight tested near Kolar on 20 June 2008. Nishant has completed development phase and user trials. The present flight tests are pre confirmatory trials before induction into services.

Test flight with Wankel engine

On Sunday 5 April 2009 DRDO launched a test flight of the Nishant UAV. The main goal was to test the performance of the Wankel engine used on the UAV. An abandoned World War II runway at a village near Kolar played host to the first ever flight of this indigenous rotary engine-powered UAV. The flight took off on early Sunday morning and climbed to an altitude of 1.8 km effortlessly before cruising for a duration of 35 minutes. The air vehicle was recovered safely at the intended place at a dried-up lake, after a total flight duration of 40 mins. The engine, a Wankel rotary type, was the developmental project of the DRDO and was jointly designed and developed by NAL, a CSIR laboratory, VRDE, Ahmednagar and ADE, Bangalore. Very few countries in the world have the capability to develop and master this technology. The provisional flight clearance for the first indigenous prototype engine was given by the certifying agency, RCMA. The engine was cleared for flight after rigorous ground endurance test runs. The Wankel engine weighs about 30 kgs, and this engine type is known for its high power to weight ratio in a single rotor category.

DRDO was satisfied with the test results. The performance of the engine during the flight met the requirements of the first flight of a engine in the air vehicle. This 55 hp indigenous engine is expected to replace the present imported engine of Nishant. The critical core engine, including the special cylinder composite nickel-silicon carbide coating and special aluminium alloy castings, was designed and developed by NAL. VRDE developed engine peripherals such as the ignition and fuel systems and ADE developed flight testing. The reconnaissance UAV, which has completed its user trials with the Indian Army, is expected to be handed over to the army shortly.

Armed forces to get more snoop-power

NEW DELHI: Defence ministry has approved another major induction of spy drones or UAVs (unmanned aerial vehicles) for armed forces, with
surveillance and intelligence-gathering missions becoming critical on the western and eastern fronts as well as along the huge coastline. Army, for instance, is going in for two more “troops” (6-8 birds each) of advanced Heron UAVs from Israel for
Rs 1,118 crore after getting the nod from the Defence Acquisitions Council headed by defence minister A K Antony.

The 1.13-million strong force has also projected a requirement of seven “troops” of the Rustom drones being developed by Defence Research and Development Organisation and Aeronautical Development Establishment in a Rs 1,000 crore project with Israeli help.

As a MALE (medium-altitude, long-endurance) drone, Rustom will be capable of operating for 24 hours, with a 300-km range and a 10,000-metre maximum altitude. Army, of course, is already inducting the indigenous Nishant and Lakshya UAVs.

Similarly, Navy’s case for two more Israeli UAVs at a cost of Rs 386 crore has also been approved, in addition to the ongoing Rs 1,163 crore joint project between Israel Aerospace Industries (IAI) and DRDO for NRUAVs (naval rotary UAVs).

Navy is already using its UAV fleet of eight Searcher-II and four Herons for maritime surveillance up to 200 nautical miles. “To be operated from warship decks, the NRUAVs will further extend the surveillance out at sea,” said an official.

Moreover, as reported earlier, Army also wants to induct a “large number” of man-portable “mini” and “micro” UAVs for short-range surveillance and NBC (nuclear, biological, chemical) detection in the battlefield.

With Army planning to induct these miniature spy drones right down to the battalion-level by 2017, it’s keen they also be capable of carrying explosives for “hard kill” of “light targets”.

Apart from regular infantry units, Para (Special Forces) battalions will also get these “stealthy” drones for covert missions beyond enemy lines and counter-terrorism operations. The armed forces had gone in for a major infusion of Israeli UAVs after the 1999 Kargil conflict and the 2002 Operation Parakram in the wake of Parliament terror attack.

At present, they have over 100 UAVs, primarily Israeli ones like Searcher-II and Heron, as also some “killer drones” designed to detect and destroy enemy radars by functioning like cruise missiles. While the aim in the 11th Plan (2007-2012) period is to also induct armed drones like the American ‘Predators’, which are being successfully used to take on Taliban in Af-Pak region with their ‘Hellfire’ missiles, the eventual objective is to have full-fledged UCAVs (unmanned combat aerial vehicles). The plan, as of now, is to further boost the snooping capabilities of armed forces as well as fully-integrate UAVs with weapon platforms for delivering precision-guided munitions.

India Scouts For HALE UAVs

Saturday, August 08, 2009

The Ministry of Defence has put out a Request for Information (RFI) to initiate the procurement of an unspecified number of High-Altitude Long Endurance (HALE) unmanned aerial vehicles (UAVs) for the Army, Navy and Air Force. The RFI specifies that the companies interested in bidding for the contract should field UAVs with a minimum baseline capability configuration of 35,000-feet ceiling altitude, 24-hour endurance, 250-km direct line-of-sight data link, 350-km relay line-of-sight data link and with a SATCOM capability.

The RFI's system overview specifies that the package should contain day and night sensor payloads, ground/aerial data relay terminals, mobile receiving stations and intra-communication systems. The RFI specifies that the fielded UAVs must demonstrate profiles including (but not limited to) all-weather day/night reconnaisance of area, axis or point, transmission of radar/IR charge couple device imagery pictures of a benchmark (to be decided) resolution, real-time engagement of targets by directing artillery fire, and as a communication relay platform to facilitate multimode and multiband communication over a wide area.

Detailing the payload requirements, the RFI lists out electro-optical payloads, laser designator of terminal homing projectiles, synthetic aperture radar (SAR), payload for electronic and communication intelligence and radar warning.

any reason why its unspecified number?
are they not decided yet on the number they need there are too many tenders floating round the ideal would be to fast channel the existing ones before new tenders are invited

DRDO lauds Humminger, VJTI students' Unmanned Aerial Vehicle

Mumbai (PTI): The Defence Research and Development Organisation (DRDO) has lauded an Unmanned Aerial Vehicle (UAV) developed by four students of the Veermata Jijabai Technological Institute (VJTI) here.

The UAV, christened the `Humminger,' won laurels at a nation-wide student-level competition for engineering students for design/development of an innovative engineering product, conducted by DRDO as part of its Golden Jubilee celebrations.

The competition focussed on developing a `deployable low-cost outdoor surveillance system,' Praveen Nair, a member of the team that developed the micro air vehicle, told PTI.

The Vertical Altitude Take-off and Landing (VTOL) design of `Humminger' makes it extremely easy to deploy and could be used for overhead surveillance of sensitive or inaccessible area, visual reconnaissance mission in an urban environment (for example, a hostage crisis) or exploratory military survey of enemy territory, he said.

The design of the team, led by Rishikesh Karande was approved by a screening committee which judged 272 entries from the country.

"The `Humminger' impressed DRDO scientists who were of the opinion that it would surely fly very well if worked on," Nair said.

The theme of the competition was developing a low cost outdoor surveillance system, basically a micro air vehicle (MAV) capable of quick deployment and live ground video capturing and streaming of target area, Nair said.

The team, which has won Rs 50,000 as prize from DRDO, credits the support given by Dr K G Narayankhedkar, Director, VJTI for the project.

Of the 272 entries, 10, including that of VJTI, were selected by DRDO. The other winners were: Thaper University Patiala, Delhi College of Engineering Delhi, Madras Institute of Technology Chennai, Sri Ram Murali Smarak College of Engineering & Technology Bareilly, IIT Madras Chennai, NIT Surathkal Manglore, Rajlaxmi College of Engineering College -Thandalam Chennai, Amity School of Engineering and Technology Noida and NIT-Silichar.

The judges for the competition were distinguished senior scientists of DRDO,Nair, a Third Year B Tech student, said. "The Humminger impressed the judges, who were of the opinion that it would fly very well if worked on," he said.

The only glitch in The Humminger's flight was a little more weight, resulting in a not very stable flight and take off, he said.

The team is now working on fixing the glitches and on further improvements in design and fabrication and would be ready with the improved Humminger model by December.

EADS Defence & Security Highlights Advanced UAV in Full Scale

At the Paris Air Show 2009, EADS Defence & Security (DS) presents the mock-up of the latest unmanned aerial system: the Advanced UAV, the proposed Franco-German-Spanish UAV programme for the development and production of a fully autonomous system for Intelligence, Surveillance, Target Acquisition and Reconnaissance (ISTAR) missions.

On the occasion of the debut of the full-scale model, DS announced the brand name "Talarion", derived from the winged sandals of Hermes in the Greek mythology, enabling him to fly over great distances and faster than anyone.

Talarion, with its 27.90 m wing span, is a joint endeavour of DS in France, Germany and Spain. The modular UAV is based upon the results of a comprehensive risk reduction study, which was concluded in May this year.

Given a governmental go-ahead for development in 2009, the maiden flight of "Talarion" would be in 2013, and with first series deliveries in 2015.

The industry proposal to the three partner nations contains six Talarion systems for France and Germany each, and three for Spain, respectively. One system consists of three Talarion units plus ground segment. In addition to the three partner nations, there is also a growing interest on the advanced UAV programme Talarion in the international markets.

Talarion is the European programme for advanced, twin-jet ISTAR solutions with a unique modular sensor / payload philosophy, providing customers unlimited control of their missions and the data obtained therein. [

UAVs As Communications Relays

August 11, 2009: A American Bat UAV was recently fitted with communications relay equipment (so that it ground units, especially those operating in mountainous terrain) could get much more range out of their radios (whose signals are often blocked by mountains). These tests with the communications relay gear were a success, and were performed for an "unmanned government customer" (most likely SOCOM or CIA, although the army and marines are also potential users).

Earlier this year, Northrup Grumman bought the Bat UAV design from Raytheon (which will continue to develop UAVs with the unique Bat design). Earlier, Raytheon had renamed the Killerbee UAV as Bat, and began scaling up the original 43 pound, 6.5 wingspan model to others with wingspans up to 33.2 feet. The Bat is a unique design, using a blended wing (like the B-2 bomber). The Bat line is competing to snag the contract to be one of the standard Department of Defense UAV models.

Raytheon had bought the Bat line from the original developer, Swift Engineering. Raytheon believes that the Bat design has a shot at being a major player in the military UAV market, but its unique design has yet to demonstrate a decisive superiority over more conventional shapes (like the Predator).

India Purchases Harop Loitering Munition

India Purchases Harop Loitering Munition

IAI to Supply HAROP System for Over $100 Million
Israel Aerospace Industries (IAI) has signed a contract to supply a HAROP Loitering Munition (LM) system to a foreign customer. The contract is estimated to be worth over $100 million.

Itzhak Nissan, President and CEO of IAI said: "HAROP is an extremely impressive system, and everyone at IAI is proud of this accomplishment. This is a state-of-the-art loitering munition system, which features accurate detection capabilities and minimizes collateral damage to the surrounding area."

Separately, the German Armed Forces and the German Ministry of Defense (MOD) have approved an operational requirement utilizing IAI's HAROP system. The project will be implemented in cooperation with Rheinmetall Defense as the prime contractor. The German MOD has already invested funds for the adaptation of HAROP to its specific requirements. Part of the adaptation was successfully performed by a joint IAI/Rheinmetall Defense team, and a follow on contract is planned for this year. This activity is a reflection of the successful cooperation between IAI and Rheinmetall Defense, which has also included projects involving Unmanned Aerial Vehicles (UAVs).

HAROP is a long endurance LM which can be launched from a variety of platforms, and is equipped with tactical UAV capabilities: high performance FLIR/ color CCD EO seeker with 3600 hemispherical coverage. It searches, detects, attacks and hits high value re-locateable, time critical, land or sea-based, moving targets with pinpoint accuracy at long ranges. A HAROP unit is comprised of LM launchers and a Mission Control Shelter (MCS) that enables missile control with a Man in the Loop operation, engagement or abort attack capability in real time, avoiding collateral damage.

The HAROP can be applied to a variety of battle scenarios, including low and high intensity conflicts, urban warfare and counter terror operations.

HAROP LMs are launched from transportable launchers and navigate towards the target area, where they loiter and search for targets. Once a target, static or moving, is detected, it is attacked and destroyed by the HAROP LM. The attack can be performed from any direction and at any attack angle, from flat to vertical which is highly essential in urban areas. The operator monitors the attack until the target is hit. Another HAROP LM can observe and send real time video of Battle Damage Assessment (BDA) to the operator. The operator can command to abort the attack in order to avoid collateral damage, returning the LM to loitering mode, and restart the attack later.

UAV in air to air combat is not a good idea i mean IAF flying offcier once said " never send a machine to do a human job " .If any IAF jet finds a UAV adversary it can take out that UAV pretty easily.UAV role should be limited to RECON missions .suppresion of air defense.As of now manned air to air combat is here to stay.it will be a sad day when UCAV will replace pilots in the air .

one marked advantage of having UCAV's in combat is that the threat to a human is reduced and with UCAV's being stealthy there is a chance that the enemy will not know what hit him at all and it the platform is downed we can always use the pusibale denial trick

true .But u see machine cannot have the same ability as a real human in the air .I mean take this hypothetical situation .a bunch of terrorist a running away from a buliding A UCAV observes it from above and launches a hell fire missile .on seeing that terrorist goes to civilian are where a lotof civilian are present .then UCAV cannot distinguish between civilian and terrorist but it will still order a land strike killing civillain as well as terrorist .whereas if human was up there he would have called off the strike
Plus it is not a good idea even after 100 years from now to give AI to weapons system .not that there gona be terminator movie like events but just because no decision is better taken by a human

UCAV's are not AI powered they are controlled by Humans on the Ground
