MQ-1L Predator Unmanned Aerial Vehicle (UAV).
A new version of the General Atomics Predator/Reaper UAV series with multiple sensor control is ready for deployment to Afghanistan after successful trials. A U.S. Army MQ-1C Gray Eagle was fitted with two additional EO/IR sensors under each wing. These were controlled by operators in the field, who were independent of the main ground control station (GCS).
While the primary Raytheon AN/AAS-53 common sensor payload (CSP) under the nose was operated via a Ku-Band tactical common datalink from AAI’s Universal GCS, two similar Raytheon DAS-2 sensors under the wings were operated by soldiers using a bidirectional one system remote video terminal (OSRVT) and Aerovironment’s mini-universal GCS designed for use with Raven and Puma small UAS. Like the U.S. Air Force Reaper, the Gray Eagle additionally carries General Atomics’ own Lynx multi-mode surveillance radar.
additional sensors are carried on the inner wing hardpoints, leaving the outer wing hardpoints free for Hellfire missiles, laser-guided bombs or other weapons. Carriage of the additional sensors requires no modification to the UAV’s power generation system.
The U.S. Army first deployed four Gray Eagle UAVs to Iraq in December 2009. Four additional aircraft were sent to Afghanistan in September 2010. An earlier version named Sky Warrior was deployed to Iraq in 2006, and is also now in Afghanistan. These UAVs were all acquired using quick reaction capability (QRC) contracts. The main Gray Eagle contract provides for 34 more aircraft and 16 GCS, for delivery beginning in December.
Gray eagle has an endurance of over 30 hours, speeds greater than 135 KTAS, can operate up to 29,000 feet, and carries 1,075 lb (488 kg) of payload. The aircraft can carry multiple payloads aloft, including Electro-optical/Infrared (EO/IR) with laser designation, Synthetic Aperture Radar (SAR), communications relay, and four Hellfire missiles.
Compared to the predator predecessor, GrayEagle’s Heavy Fuel Engine (HFE) supports the Army’s “single fuel in the battlefield” concept, and provides increased horsepower and significantly improved fuel efficiency, utilizing either jet or diesel fuel.
An extremely reliable UAS, Gray Eagle features a fault-tolerant control system and a triple-redundant avionics system architecture, similar to the systems integrated in the battle-proven Predator B Designed with airworthiness as a primary consideration, Gray Eagle is engineered to meet and exceed manned aircraft reliability standards.
This long-range, long-dwell UAS is dedicated to direct operational control by Army field commanders. Its expansive mission set includes, but is not limited, to wide-area Intelligence Surveillance, Reconnaissance (ISR), convoy protection, Improvised Explosive Device (IED) detection and defeat, close air support, communications relay, and weapons delivery missions.

Controlled by the U.S. Army One System Ground Control Station (OSGCS)
The General Atomics MQ-1 Predator is an unmanned aerial vehicle (UAV) used primarily by the United States Air Force (USAF) and Central Intelligence Agency (CIA). Initially conceived in the early 1990s for reconnaissance and forward observation roles, the Predator carries cameras and other sensors but has been modified and upgraded to carry and fire two AGM-114 Hellfire missiles or other munitions. The aircraft, in use since 1995, has seen combat over Afghanistan, Pakistan, Bosnia, Serbia, Iraq, Yemen, Libya, and Somalia.
The USAF describes the Predator as a “Tier II” MALE UAS (medium-altitude, long-endurance unmanned aircraft system). The UAS consists of four aircraft or “air vehicles” with sensors, a ground control station (GCS), and a primary satellite link communication suite. Powered by a Rotax engine and driven by a propeller, the air vehicle can fly up to 400 nautical miles (740 km) to a target, loiter overhead for 14 hours, then return to its base.
Following 2001, the RQ-1 Predator drone became the primary UAV used for offensive operations by the USAF and the Central Intelligence Agency (CIA) in Afghanistan and the Pakistani tribal areas. It has also been deployed in other locations. Because offensive uses of the Predator are classified, U.S. military officials have reported an appreciation for the intelligence and reconnaissance-gathering abilities of UAVs but declined to publicly discuss their offensive use.
Civilian applications have included border enforcement and scientific studies.

The Central Intelligence Agency (CIA) and the Pentagon began experimenting with reconnaissance drones in the early 1980s. The CIA preferred small, lightweight, unobtrusive drones, in contrast to the USAF. In the early 1990s, the CIA became interested in the “Amber”, a drone developed by Leading Systems Inc. The company’s owner, Abraham Karem was the former chief designer for the Israeli Air Force, and had immigrated to the United States in the late 1970s. Karem’s company had since gone bankrupt and been bought up by a U.S. defense contractor. The CIA secretly bought five drones (now called the “Gnat”) from them. Karem agreed to produce a quiet engine for the vehicle, which had until then sounded like “a lawnmower in the sky”. The new development became known as the “Predator”.
General Atomics Aeronautical Systems (GA) was awarded a contract to develop the Predator in January 1994, and the initial Advanced Concept Technology Demonstration (ACTD) phase lasted from January 1994 to June 1996. The aircraft itself was a derivative of the GA Gnat 750 UAV. During the ACTD phase, three systems were purchased from GA, comprising twelve aircraft and three ground control stations.
From April through May, 1995, the Predator ACTD aircraft were flown as a part of the Roving Sands 1995 exercises in the U.S. The exercise operations were successful, and this led to the decision to deploy the system to the Balkans later in the summer of 1995.
During the ACTD, Predators were operated by a combined Army/Navy team managed by the Navy’s Joint Program Office for Unmanned Aerial Vehicles (JPO-UAV) and first deployed to Gjader, Albania, for operations in the Former Yugoslavia in Spring 1995.
By the start of the United States Afghan campaign in 2001, the USAF had acquired 60 Predators, and said it had lost 20 of them in action. Few if any of the losses were from enemy action, the worst problem apparently being foul weather, particularly icy conditions. Some critics within the Pentagon saw the high loss rate as a sign of poor operational procedures. In response to the losses caused by cold weather flight conditions, a few of the later Predators obtained by the USAF were fitted with de-icing systems, along with an uprated turbocharged engine and improved avionics. This improved “Block 1” version was referred to as the “RQ-1B”, or the “MQ-1B” if it carried munitions; the corresponding air vehicle designation was “RQ-1L” or “MQ-1L”
The Predator system was initially designated the RQ-1 Predator. The “R” is the United States Department of Defense designation for reconnaissance and the “Q” refers to an unmanned aircraft system. The “1” describes it as being the first of a series of aircraft systems built for unmanned reconnaissance. Pre-production systems were designated as RQ-1A, while the RQ-1B (not to be confused with the RQ-1 Predator B, which became the MQ-9 Reaper) denotes the baseline production configuration. These are designations of the system as a unit. The actual aircraft themselves were designated RQ-1K for pre-production models, and RQ-1L for production models. In 2002, the USAF officially changed the designation to MQ-1 (“M” for multi-role) to reflect its growing use as an armed aircraft.
Command and sensor systems
During the campaign in the former Yugoslavia, a Predator’s pilot would sit with several payload specialists in a van near the runway of the drone’s operating base. Direct radio signals controlled the drone’s takeoff and initial ascent. Then communications shifted to military satellite networks linked to the pilot’s van. Pilots experienced a delay of several seconds between tugging their joysticks and the drone’s response. But by 2000 improvements in communications systems (perhaps by use of the USAF’s JSTARS system) made it possible, at least in theory, to fly the drone remotely from great distances. It was no longer necessary to use close-up radio signals during the Predator’s takeoff and ascent. The entire flight could be controlled by satellite from any command center with the right equipment. The CIA proposed to attempt over Afghanistan the first fully remote Predator flight operations, piloted from the agency’s headquarters at Langley.
The Predator air vehicle and sensors are controlled from the ground station via a C-band line-of-sight data link or a Ku-band satellite data link for beyond-line-of-sight operations. During flight operations the crew in the ground control station is a pilot and two sensor operators. The aircraft is equipped with the AN/AAS-52 Multi-spectral Targeting System, a color nose camera (generally used by the pilot for flight control), a variable aperture day-TV camera, and a variable aperture infrared camera (for low light/night). Previously, Predators were equipped with a synthetic aperture radar for looking through smoke, clouds or haze, but lack of use validated its removal to reduce weight and conserve fuel. The cameras produce full motion video and the synthetic aperture radar produced still frame radar images. There is sufficient bandwidth on the datalink for two video sources to be used at one time, but only one video source from the sensor ball can be used at any time due to design limitations. Either the daylight variable aperture or the infrared electro-optical sensor may be operated simultaneously with the synthetic aperture radar, if equipped.
All later Predators are equipped with a laser designator that allows the pilot to identify targets for other aircraft and even provide the laser-guidance for manned aircraft. This laser is also the designator for the AGM-114 Hellfire that are carried on the MQ-1.

Each Predator air vehicle can be disassembled into six main components and loaded into a container nicknamed “the coffin.” This enables all system components and support equipment to be rapidly deployed worldwide. The largest component is the ground control station and it is designed to roll into a C-130 Hercules. The Predator primary satellite link consists of a 6.1 meter (20 ft) satellite dish and associated support equipment. The satellite link provides communications between the ground station and the aircraft when it is beyond line-of-sight and is a link to networks that disseminate secondary intelligence. The RQ-1A system needs 1,500 by 40 meters (5,000 by 125 ft) of hard surface runway with clear line-of-sight to each end from the ground control station to the air vehicles. Initially, all components needed to be located on the same airfield
Currently, the U.S. Air Force uses a concept called “Remote-Split Operations” where the satellite datalink is located in a different location and is connected to the GCS through fiber optic cabling. This allows Predators to be launched and recovered by a small “Launch and Recovery Element” and then handed off to a “Mission Control Element” for the rest of the flight. This allows a smaller number of troops to be deployed to a forward location, and consolidates control of the different flights in one location.
The improvements in the MQ-1B production version include an ARC-210 radio, an APX-100 IFF/SIF with mode 4, a glycol-weeping “wet wings” ice mitigation system, up-graded turbo-charged engine, fuel injection, longer wings, dual alternators as well as other improvements.
On May 18, 2006, the Federal Aviation Administration (FAA) issued a certificate of authorization which will allow the M/RQ-1 and M/RQ-9 aircraft to be used within U.S. civilian airspace to search for survivors of disasters. Requests had been made in 2005 for the aircraft to be used in search and rescue operations following Hurricane Katrina, but because there was no FAA authorization in place at the time, the assets were not used. The Predator’s infrared camera with digitally-enhanced zoom has the capability of identifying the heat signature of a human body from an altitude of 3 km (10,000 ft), making the aircraft an ideal search and rescue tool.
The longest declassified Predator flight to date lasted for 40 hours, 5 minutes. The total flight time has reached 1 million hours as of April 2010.
 Armed version development
Close up of the Hellfire missile pylon, 2004.
The USAF handed the Predator over to the service’s Big Safari office after the Kosovo campaign in order to accelerate tests of the UAV in a strike role, fitted with reinforced wings and stores pylons to carry munitions, as well as a laser designator. This effort led to a series of tests, on February 21, 2001, in which the Predator fired three Hellfire anti-armor missiles, scoring hits on a stationary tank with all three missiles. The scheme was put into service, with the armed Predators given the new designation of MQ-1A. Given that a Predator is very unobtrusive and the Hellfire is supersonic, such a combination gives little warning of attack.
In the winter of 2000–2001, after seeing the results of Predator reconnaissance in Afghanistan (see below), Cofer Black, head of the CIA’s Counterterrorist Center (CTC), became a “vocal advocate” of arming the Predator with missiles to target Osama bin Laden in the country. He also believed that CIA pressure and practical interest was causing the USAF’s armed Predator program to be significantly accelerated. Black, and “Richard”, who was in charge of the CTC’s Bin Laden Issue Station, continued to press during 2001 for a Predator armed with Hellfire missiles.
Further weapons tests occurred between May 22 and June 7, 2001, with mixed results. While missile accuracy was excellent, there were some problems with missile fuzing….” In the first week of June, in the Nevada Desert, a Hellfire missile was successfully launched on a replica of bin Laden’s Afghanistan Tarnak residence. A missile launched from a Predator exploded inside one of the replica’s rooms; it was concluded that any people in the room would have been killed. However, the armed Predator did not go into action before the September 11 attacks.
The USAF has also investigated using the Predator to drop battlefield ground sensors and to carry and deploy the “Finder” mini-UAV.
NASA and NPGS unarmed research versions
Two unarmed versions, known as the General Atomics ALTUS were built, ALTUS I for the Naval Postgraduate School and ALTUS II for the NASA ERAST Project in 1997 and 1996, respectively.
 MQ-1C Warrior/Grey Eagle
Main article: General Atomics MQ-1C Grey Eagle
The U.S. Army selected the MQ-1C Warrior as the winner of the Extended-Range Multi-Purpose UAV competition August 2005, and the type became operational in 2009.
As of March 2009, the U.S. Air Force had 195 MQ-1 Predators and 28 MQ-9 Reapers in operation. Predators and Reapers fired missiles 244 times in Iraq and Afghanistan in 2007 and 2008. A report in March 2009 indicated that U.S. Air Force had lost 70 Predators in air crashes during its operational history. Fifty-five were lost to equipment failure, operator error, or weather. Four have been shot down in Bosnia, Kosovo, or Iraq. Eleven more were lost to operational accidents on combat missions.
On March 3, 2011, the U.S. Air Force took delivery of its last MQ-1 Predator in a ceremony at General Atomics’ flight operations facility. Since its first flight in July 1994, the MQ-1 series has accumulated over 900,000 flight hours and maintained a fleet fully mission capable rate over 90 percent.
Squadrons and operational units
During the initial ACTD phase, the United States Army led the evaluation program, but in April 1996, the Secretary of Defense selected the U.S. Air Force as the operating service for the RQ-1A Predator system. The 3rd Special Operations Squadron at Cannon Air Force Base, 11th, 15th, and 17th Reconnaissance Squadrons, Creech Air Force Base, Nevada, and the Air National Guard’s 163d Reconnaissance Wing at March Air Reserve Base, California, currently operate the MQ-1.
In 2005, the U.S. Department of Defense recommended retiring Ellington Field’s 147th Fighter Wing’s F-16 Fighting Falcon fighter jets (a total of 15 aircraft), which was approved by the Base Realignment and Closure committee. They will be replaced with 12 MQ-1 Predator UAVs, and the new unit should be fully equipped and outfitted by 2009. The wing’s combat support arm will remain intact. The 272nd Engineering Installation Squadron, an Air National Guard unit currently located off-base, will move into Ellington Field in its place.
The 3rd Special Operations Squadron is currently the largest Predator squadron in the United States Air Force.
U.S. Customs and Border Protection is operating an unknown number of Predato
On June 21, 2009, the United States Air Force announced that it was creating a new MQ-1 squadron at Whiteman Air Force Base that would become operational by February 2011. In September 2011, the US Air Guard announced that despite current plans for budget cuts, they will continue to operate the Air Force’s combat UAVs, including MQ-1B.
 In the Balkans
A shot down RQ-1 Predator in the Museum of Aviation in Belgrade, Serbia
The first overseas deployment took place in the Balkans, from July to November 1995, under the name Nomad Vigil. Operations were based in Gjader, Albania. At least two Predators were lost during Nomad Vigil, one of them to hostile fire.
Several others were destroyed in the course of Operation Noble Anvil, the 1999 NATO bombing of Yugoslavia:
One aircraft (serial 95-3017) was lost on April 18, 1999, following fuel system problems and icing.
A second aircraft (serial 95-3019) was lost on May 13, when it was shot down by a Serbian Strela-1M surface-to-air missile over the village of Biba. A Serbian TV crew videotaped this incident.
A third aircraft (serial number 95-3021) crashed on May 20 near the town of Talinovci, and Serbian news reported that this, too, was the result of anti-aircraft fire.
In 2000 a joint CIA-Pentagon effort was agreed to locate Osama bin Laden in Afghanistan. Dubbed “Afghan Eyes”, it involved a projected 60-day trial run of Predators over the country. The first experimental flight was held on September 7, 2000. White House security chief Richard A. Clarke was impressed by the resulting video footage; he hoped that the drones might eventually be used to target Bin Laden with cruise missiles or armed aircraft. Clarke’s enthusiasm was matched by that of Cofer Black, head of the CIA’s Counterterrorist Center (CTC), and Charles Allen, in charge of the CIA’s intelligence-collection operations. The three men backed an immediate trial run of reconnaissance flights. Ten out of the ensuing 15 Predator missions over Afghanistan were rated successful. On at least two flights, a Predator spotted a tall man in white robes at bin Laden’s Tarnak Farm compound outside Kandahar; the figure was subsequently deemed to be “probably bin Laden”. By October 2000, deteriorating weather conditions made it difficult for the Predator to fly from its base in Uzbekistan, and the flights were suspended.
On February 16, 2001 at Nellis Air Force base, a Predator successfully fired three Hellfire AGM-114C missiles into a target. The newly armed Predators were given the designation of MQ-1A. In the first week of June, 2001, a Hellfire missile was successfully launched on a replica of bin Laden’s Afghanistan Tarnak residence built at a Nevada testing site. A missile launched from a Predator exploded inside one of the replica’s rooms; it was concluded that any people in the room would have been killed. On September 4, 2001 (after the Bush cabinet approved a Qaeda/Taliban plan) CIA chief Tenet order the agency to resume reconnaissance flights. The Predators were now weapons-capable, but didn’t carry missiles because the host country (presumably Uzbekistan) hadn’t granted permission.
Subsequent to 9/11, approval was quickly granted to ship the missiles, and the Predator aircraft and missiles reached their overseas location on September 16, 2001. The first mission was flown over Kabul and Kandahar on September 18 without carrying weapons. Subsequent host nation approval was granted on October 7 and the first armed mission was flown on the same day. On February 4, 2002, an armed Predator attacked a convoy of sport utility vehicles, killing a suspected al Qaeda leader. The intelligence community initially expressed doubt that he was Osama bin Laden.
On March 4, 2002, a CIA-operated Predator fired a Hellfire missile into a reinforced Taliban machine gun bunker that had pinned down an Army Ranger team whose CH-47 Chinook had crashed on the top of Takur Ghar Mountain in Afghanistan. Previous attempts by flights of F-15 and F-16 Fighting Falcon aircraft were unable to destroy the bunker. This action took place during what has become known as the “Battle of Robert’s Ridge”, a part of Operation Anaconda. This appears to be the first use of such a weapon in a close air support role.
On April 6, 2011, the Predator scored its first friendly fire deaths when observers at a remote location did not relay their doubts about the target to the operators at Creech Air Force Base.
Main article: Drone attacks in Pakistan by the United States
Since at least 2004, the U.S. Central Intelligence Agency has allegedly been operating the drones out of Shamsi airfield in Pakistan to attack militants in Pakistan’s Federally Administered Tribal Areas.
Since May 2005 the MQ-1 Predator fitted with Hellfire missiles has been successfully used to kill a number of prominent al Qaeda operatives. The use of the Predator has also resulted in a number of civilian deaths, particularly on January 13, 2006 when 18 civilians were killed. According to Pakistani authorities, the U.S. strike was based on faulty intelligence.
An MQ-1B Predator from the 361st Expeditionary Reconnaissance Squadron takes off July 9, 2008 from Ali Base, Iraq.
An Iraqi MiG-25 shot down a Predator performing reconnaissance over the no fly zone in Iraq on December 23, 2002. This was the first time in history a conventional aircraft and a drone had engaged each other in combat. Predators had been armed with AIM-92 Stinger air-to-air missiles, and were being used to “bait” Iraqi fighters, then run. In this incident, the Predator did not run, but instead fired one of its Stingers. The Stinger’s heat-seeker became “distracted” by the MiG’s missile and missed the MiG. The Predator was hit by the MiG’s missile and destroyed. Another two Predators had been shot down earlier by Iraqi SAMs, one of them on September 11, 2001.
During the initial phases of the 2003 U.S. invasion of Iraq, a number of older Predators were stripped down and used as decoys to entice Iraqi air defenses to expose themselves by firing. From July 2005 to June 2006, the 15th Reconnaissance Squadron participated in more than 242 separate raids, engaged 132 troops in contact-force protection actions, fired 59 Hellfire missiles; surveyed 18,490 targets, escorted four convoys, and flew 2,073 sorties for more than 33,833 flying hours.
Iraqi insurgents intercepted video feeds, which were not encrypted, using a piece of Russian software named SkyGrabber. The encryption for the ROVER feeds were removed for performance reasons.
Main article: CIA activities in Yemen
On November 3, 2002, a Hellfire missile was fired at a car in Yemen, killing Qaed Salim Sinan al-Harethi, an al-Qaeda leader thought to be responsible for the USS Cole bombing. It was the first direct U.S. strike in the War on Terrorism outside Afghanistan.
In 2004, the Australian Broadcasting Corporation’s (ABC-TV) international affairs program Foreign Correspondent investigated this targeted killing and the involvement of then U.S. Ambassador as part of a special report titled “The Yemen Option”. The report also examined the evolving tactics and countermeasures in dealing with Al Qaeda inspired attacks.
On 30 September 2011, a Hellfire fired from an American UAV killed Anwar al-Awlaki, an American-born cleric and Al Qaeda leader, in Yemen.. Also killed was Samir Khan, an American born in Saudi Arabia, who was editor of al-Qaeda’s English-language webzine, Inspire (magazine).
U.S Air Force MQ-1B Predators have been involved in reconnaissance and strike sorties in Operation Unified Protector. An MQ-1B fired its first hellfire in the conflict on April 23, 2011, striking a BM-21 Grad. There are also some suggestions that a Predator was involved in the final attack against Gaddafi.
It has also been used by the Italian Air Force since the end of 2004 and by the Royal Air Force since 2006. Two civil-registered unarmed MQ-1s have been operated by the Office of the National Security Advisor in the Philippines since 2006.
