Unmanned combat aerial vehicle
An unmanned combat aerial vehicle (UCAV), also known as a combat drone, fighter drone or battlefield UAV, is an unmanned aerial vehicle (UAV) that carries aircraft ordnance such as air-to-surface missiles, anti-tank guided missiles (ATGMs), and/or aerial bombs on hardpoints or within weapons bay, allowing it to perform tactical attacks known as drone strikes. UCAVs are used for intelligence, surveillance, target acquisition and reconnaissance, attacking high-value targets and prolonged loitering before needing to return to base, unlike kamikaze drones, which are single-use drones made for physically ramming into a target and exploding on impact; or surveillance drones, which are unarmed drones used only for aerial reconnaissance and gathering intelligence.
Aircraft of this type have no onboard human pilot, but are usually under real-time remote control by human operators, with varying levels of automation. As the operator runs the vehicle from a remote terminal via radio control, equipment necessary to support an on-board human pilot is not needed, resulting in a lower weight and a smaller size than a manned aircraft for the same payload. Many countries have operational domestic UCAVs, and many more have imported fighter drones or are in the process of developing them.
One of the earliest explorations of the concept of the combat drone was by Lee de Forest, an early inventor of radio devices, and U. A. Sanabria, a TV engineer. They presented their idea in an article in a 1940 publication of Popular Mechanics. The modern military drone was the brainchild of John Stuart Foster Jr., a nuclear physicist of Lawrence Livermore Laboratory. In 1971, Foster was a model airplane hobbyist and had the idea this hobby could be applied to building weapons. He drew up plans and by 1973 DARPA (Defense Advanced Research Projects Agency) built two prototypes called "Prairie" and "Calera". They were powered by a modified lawn-mower engine and could stay aloft for two hours while carrying a 28-pound (13 kg) load.
In the 1973 Yom Kippur War, Israel used unarmed U.S. Ryan Firebee target drones to spur Egypt into firing its entire arsenal of anti-aircraft missiles. This mission was accomplished with no injuries to Israeli pilots, who soon exploited the depleted Egyptian defences. In the late 1970s and 80s, Israel developed the Scout and the Pioneer, which represented a shift toward the modern lighter, glider-type model of UAV. Israel pioneered the use of unmanned aerial vehicles (UAVs) for real-time surveillance, electronic warfare, and decoys. The images and radar decoying provided by these UAVs helped Israel to completely neutralize the Syrian air defenses in Operation Mole Cricket 19 at the start of the 1982 Lebanon War, resulting in no pilots downed.
In the late 1980s, Iran deployed a drone armed with six RPG-7 rounds in the Iran–Iraq War.
Impressed by Israel's success, the US quickly acquired a number of UAVs, and its Hunter and Pioneer systems are direct derivatives of Israeli models. The first 'UAV war' was the first Persian Gulf War: according to a May 1991 Department of the Navy report: "At least one UAV was airborne at all times during Desert Storm." After the Persian Gulf War successfully demonstrated its utility, global militaries invested widely in the domestic development of combat UAVs. The first "kill" by an American UAV was on October 7, 2001, in Kandahar.
Between 2004 to late 2012, the U.S. has increased its use of drone strikes against targets in Pakistan and elsewhere as part of the War on Terror. In January 2014, it was estimated that 2,400 people had died from U.S. drone strikes in five years. In June 2015, the total death toll of U.S. drone strikes was estimated to exceed 6,000.
In 2020, Turkey became the first country to use UCAVs in a large, coordinated attack on a conventional battlefield when it attacked forces in Syria. They were used to attack enemy positions, to provide cover for ground forces and to scout for artillery. Drones were used extensively in the 2020 Nagorno-Karabakh war between Azerbaijan and Armenia. Azerbaijan's use of cheaper Turkish TB2 drones was seen as crucial to their victory against the Armenian forces.
