A military UAV may carry and fire munitions on board, while a cruise missile is a munition. Loitering munitions are a class of unmanned aircraft intermediate between them. The earliest recorded use of an unmanned aerial vehicle for warfighting occurred in July 1849, serving as
570-783: A drone , is an aircraft with no human pilot , crew, or passengers on board. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications. These include aerial photography , area coverage, precision agriculture , forest fire monitoring, river monitoring, environmental monitoring , policing and surveillance, infrastructure inspections, smuggling, product deliveries , entertainment, and drone racing . Many terms are used for aircraft which fly without any persons on board. The term drone has been used from
684-490: A "powered, aerial vehicle that does not carry a human operator, uses aerodynamic forces to provide vehicle lift, can fly autonomously or be piloted remotely, can be expendable or recoverable, and can carry a lethal or nonlethal payload". UAV is a term that is commonly applied to military use cases. Missiles with warheads are generally not considered UAVs because the vehicle itself is a munition, but certain types of propeller-based missile are often called " kamikaze drones " by
798-479: A UAV that could remain in the air for a long time has been around for decades, but only became an operational reality in the 21st century. Endurance UAVs for low-altitude and high-altitude operation, the latter sometimes referred to as "high-altitude long-endurance (HALE)" UAVs, are now in full service. On August 21, 1998, an AAI Aerosonde named Laima becomes the first UAV to cross the Atlantic Ocean, completing

While all 50 IIIAs were built, only 28 of the IIIBs were completed as intended, as a new improved bomber/reconnaissance floatplane, the Fairey IIIC was available, of which 36 were produced, which reverted to short equal-span wings like the IIIA but was powered by the much more powerful and reliable 375 hp (280 kW) Rolls-Royce Eagle VIII engine and could still carry
1026-441: A camera) that weigh considerably less than an adult human, and as a result, can be considerably smaller. Though they carry heavy payloads, weaponized military UAVs are lighter than their crewed counterparts with comparable armaments. Small civilian UAVs have no life-critical systems , and can thus be built out of lighter but less sturdy materials and shapes, and can use less robustly tested electronic control systems. For small UAVs,
1140-574: A component of an unmanned aircraft system ( UAS ), which also includes a ground-based controller and a system of communications with the aircraft. The term UAS was adopted by the United States Department of Defense (DoD) and the United States Federal Aviation Administration (FAA) in 2005 according to their Unmanned Aircraft System Roadmap 2005–2030. The International Civil Aviation Organization (ICAO) and

Miniaturization means that less-powerful propulsion technologies can be used that are not feasible for crewed aircraft, such as small electric motors and batteries. Control systems for UAVs are often different from crewed craft. For remote human control, a camera and video link almost always replace
5472-533: The reconnaissance mission proved highly successful. A series of reconnaissance drones derived from the Firebee, the Ryan Model 147 Lightning Bug series, were used by the US to spy on North Vietnam , Communist China, and North Korea in the 1960s and early 1970s. The Lightning Bugs were not the only long-range reconnaissance drones developed in the 1960s. The US developed other, more specialized reconnaissance drones:
5586-633: The seaplane tender HMS Pegasus in support of the North Russian Expeditionary Force . They were used to carry out bombing attacks against Bolshevik shipping and rail communications. The IIID was operated by the Royal Air Force and Fleet Air Arm as well as the Naval Aviation of Portugal (11 aircraft) and the air forces of Australia . Australia received six IIIDs, the first being delivered in August 1921. In 1924 ,
5700-606: The "A" code would be also used for "Attack" aircraft, later "full-sized" targets would be given the "PQ" designation. USAAF acquired hundreds of Culver "PQ-8" target drones, which were radio-controlled versions of the tidy little Culver Cadet two-seat light civil aircraft, and thousands of the improved Culver PQ-14 Cadet derivative of the PQ-8. The US also used RC aircraft, including modified B-17 Flying Fortress and B-24 Liberator heavy bombers in Aphrodite and Anvil operations in combat on
5814-400: The "DH.82B Queen Bee", derived from the de Havilland Tiger Moth biplane trainer. The name of "Queen Bee" allegedly led to the use of the term "drone" for pilotless aircraft, particularly when they are radio-controlled. During this period, the U.S. Navy , continuing work that reached back to 1917, also experimented with radio-controlled aircraft. In 1936 the head of US Navy research group used

In 1973, the U.S. military officially confirmed that they had been using UAVs in Southeast Asia (Vietnam). Over 5,000 U.S. airmen had been killed and over 1,000 more were missing or captured . The USAF 100th Strategic Reconnaissance Wing flew about 3,435 UAV missions during
6270-618: The 1980s and 1990s, interest in UAVs grew within the higher echelons of the U.S. military. The U.S. funded the Counterterrorism Center (CTC) within the CIA, which sought to fight terrorism with the aid of modernized drone technology. In the 1990s, the U.S. DoD gave a contract to AAI Corporation along with Israeli company Malat. The U.S. Navy bought the AAI Pioneer UAV that AAI and Malat developed jointly. Many of these UAVs saw service in

About 211 AQM-34Ls were lost during the war. The highest mission bird was a 147SC, named "Tom Cat", it accomplished 68 combat missions in Vietnam, before failing to return on 25 September 1974. Tom Cat was followed by Budweiser (with 63 missions), Ryan's Daughter (52 missions), and Baby Duck (46 missions). The largest UAVs in Vietnam were
7980-423: The Syrian air defenses at the start of the 1982 Lebanon War , resulting in no pilots downed. In Israel in 1987, UAVs were first used as proof-of-concept of super-agility, post-stall controlled flight in combat-flight simulations that involved tailless, stealth-technology-based, three-dimensional thrust vectoring flight-control, and jet-steering. With the maturing and miniaturization of applicable technologies in
8094-424: The Tonkin Gulf between naval units of the U.S. and the North Vietnamese Navy initiated America's highly classified UAVs ( Ryan Model 147 , Ryan AQM-91 Firefly , Lockheed D-21 ) into their first combat missions of the Vietnam War . When the Chinese government showed photographs of downed U.S. UAVs via Wide World Photos , the official U.S. response was "no comment". During the War of Attrition (1967–1970) in
8208-456: The UAV industry, is projected to experience a compound annual growth rate of 4.8% over the next decade. This represents a near doubling in market size, from $ 12.5 billion in 2024 to an estimated $ 20 billion by 2034. Crewed and uncrewed aircraft of the same type generally have recognizably similar physical components. The main exceptions are the cockpit and environmental control system or life support systems . Some UAVs carry payloads (such as
8322-585: The UAV units to deploy immediately for Southeast Asia on any available C-130s or C-133s . The first birds (drones) would be Ryan 147Bs (AQM-34s) piggy-backed on C-130s, after completing their missions they would be parachuted for recovery near Taiwan . USAF drones (UAVs) of the Strategic Air Command deployed to the Republic of South Vietnam (RVN) as the 4025th Strategic Reconnaissance Squadron, 4080th Strategic Reconnaissance Wing in 1964. In 1966
8436-968: The UAVs controlled and relaying data back over high-bandwidth data links in real time, linked to ground, air, sea, and space platforms. The trend had been emerging before the American war in Afghanistan began in 2001, but was greatly accelerated by the use of UAVs in that conflict. The Predator RQ-1L UAV (General Atomics) was the first deployed UAV to the Balkans in 1995 Iraq in 1996 and was proved very effective in Operation Iraqi Freedom as well as Afghanistan. Another growth field in UAVs are miniature UAVs, ranging from " micro aerial vehicles (MAVs)" and miniature UAVs that can be carried by an infantryman to UAVs that can be carried and launched like an infantry man-portable air-defense system . The idea of designing
8550-503: The advances of computing technology, beginning with analog controls and evolving into microcontrollers, then system-on-a-chip (SOC) and single-board computers (SBC). Modern system hardware for UAV control is often called the flight controller (FC), flight controller board (FCB) or autopilot. Common UAV-systems control hardware typically incorporate a primary microprocessor, a secondary or failsafe processor, and sensors such as accelerometers, gyroscopes, magnetometers, and barometers into
8664-484: The cockpit windows; radio-transmitted digital commands replace physical cockpit controls. Autopilot software is used on both crewed and uncrewed aircraft, with varying feature sets. UAVs can be designed in different configurations than manned aircraft both because there is no need for a cockpit and its windows, and there is no need to optimize for human comfort, although some UAVs are adapted from piloted examples, or are designed for optionally piloted modes. Air safety
8778-593: The concept of an unmanned aircraft. They were intended for use as "aerial torpedoes" an early version of today's cruise missiles . Control was achieved using gyroscopes developed by Elmer Sperry of the Sperry Gyroscope Company . Later, in November 1917, the Automatic Airplane was flown for representatives of the US Army. This led the army to commission a project to build an "aerial torpedo", resulting in
8892-610: The construction of the Kettering Bug by Charles Kettering from Dayton, Ohio and the Hewitt-Sperry Automatic Airplane – initially meant as an uncrewed plane that would carry an explosive payload to a predetermined target. Development continued during World War I, when the Dayton-Wright Airplane Company invented a pilotless aerial torpedo that would explode at a preset time. The film star and model-airplane enthusiast Reginald Denny developed
9006-409: The control of a microcontroller unit (MCU). Flapping-wing ornithopters , imitating birds or insects, have been flown as microUAVs . Their inherent stealth recommends them for spy missions. Sub-1g microUAVs inspired by flies, albeit using a power tether, have been able to "land" on vertical surfaces. Other projects mimic the flight of beetles and other insects. UAV computing capability followed
9120-622: The crew were rescued. A small number of civil operated IIIDs and IIIFs were used for survey duties in the 1920s and 30s, while in October 1934 a single IIIF was entered into the MacRobertson Air Race , reaching the finishing line in Melbourne but too late to be classed as completing the race. A single example of the Fairey III is preserved in Portugal's Museu de Marinha (Naval Museum). This
9234-511: The degree of autonomy in their flight operations. ICAO classifies unmanned aircraft as either remotely piloted aircraft or fully autonomous. Some UAVs offer intermediate degrees of autonomy. For example, a vehicle may be remotely piloted in most contexts but have an autonomous return-to-base operation. Some aircraft types may optionally fly manned or as UAVs, which may include manned aircraft transformed into manned or Optionally Piloted UAVs (OPVs). The flight of UAVs may operate under remote control by
9348-517: The downing of the U-2, the highly classified UAV (called RPV back then) program was born, under the code name of Red Wagon. Just after the incident involving the US Navy destroyers USS Maddox (DD-731) and USS Turner Joy (DD-951) , and even before it escalated into the presidential " Tonkin Gulf Resolution " and war with North Vietnam , the USAF had issued an immediate order for
9462-559: The drone and a six-inch television screen in the TG-2 control aircraft in 1941. In April 1942 the assault drone successfully delivered a demonstration torpedo attack on a US destroyer at a range of 20 miles from the TG-2 control aircraft. Another assault drone was successfully crashed into a target moving at eight knots. The Navy Bureau of Aeronautics then proposed a television-assisted remote control assault drone program of 162 control planes and 1,000 assault drones. Disagreements arose within
9576-539: The early days of aviation , some being applied to remotely flown target aircraft used for practice firing of a battleship's guns, such as the 1920s Fairey Queen and 1930s de Havilland Queen Bee . Later examples included the Airspeed Queen Wasp and Miles Queen Martinet , before ultimate replacement by the GAF Jindivik . The term remains in common use. In addition to the software, autonomous drones also employ
9690-469: The first scaled remote piloted vehicle in 1935. Soviet researchers experimented with controlling Tupolev TB-1 bombers remotely in the late 1930s. In 1940, Denny started the Radioplane Company and more models emerged during World War II – used both to train antiaircraft gunners and to fly attack-missions. Nazi Germany produced and used various UAV aircraft during the war, like
9804-495: The flight in 26 hours. The idea of using UAVs as a cheaper alternative to satellites for atmospheric research, earth and weather observation, and particularly communications goes back at least to the late 1950s, with conceptual studies focused on UAVs with conventional propulsion, or new forms of propulsion using microwave beamed power or photovoltaic solar cells. Drone (aircraft) An unmanned aerial vehicle ( UAV ), or unmanned aircraft system ( UAS ), commonly known as
9918-553: The ground pilot. The US Navy began experimenting with radio-controlled aircraft during the 1930s as well, resulting in the Curtiss N2C-2 drone in 1937. The N2C-2 was remotely controlled from another aircraft, called a TG-2. N2C-2 anti-aircraft target drones were in service by 1938. The US Army Air Forces (USAAF) adopted the N2C-2 concept in 1939. Obsolescent aircraft were put into service as "A-series" anti-aircraft target drones. Since
10032-529: The late 1950s, along with the Falconer, the US Army acquired another reconnaissance drone, the Aerojet-General SD-2 Overseer . It had a similar configuration to the Falconer, but featured a vee tail and was about twice as heavy. The success of drones as targets led to their use for other missions. The well-proven Ryan Firebee was a good platform for such experiments , and tests to evaluate it for
10146-483: The loss rate is high, but we are willing to risk more of them ...they save lives!" During the 1973 Yom Kippur War , Soviet-supplied surface-to-air missile -batteries in Egypt and Syria caused heavy damage to Israeli fighter jets . As a result, Israel developed the IAI Scout as the first UAV with real-time surveillance. The images and radar decoys provided by these UAVs helped Israel to completely neutralize
10260-528: The missions over enemy territory. The average sortie per drone was three missions, before it was lost. The most famous Lightning Bug was a 147SC drone named "Tom Cat." Tom Cat flew sixty-eight missions before an enemy gunner finally brought him "down over Hanoi on September 25, 1974." From August 1964, until their last combat flight on 30 April 1975 (the fall of Saigon ), the USAF 100th Strategic Reconnaissance Wing would launch 3,435 Ryan reconnaissance drones over North Vietnam and its surrounding areas, at
10374-788: The only spy plane available to the US was the U-2 . Spy satellites were another year and half away, and the SR-71 Blackbird was still on the drawing board. In such a climate, concerns appeared about the negative publicity from the foreseen capture of US airmen on the communist territory. Pilots' fears were realized in May 1960, when U-2 pilot Francis Gary Powers was shot down over the USSR. Not surprisingly, work intensified on an unmanned drone which would be capable of penetrating deep into enemy territory, and return with precise military intelligence. Within three months of
10488-633: The piston-powered KDG Snipe of 1946, which evolved through the KD2G and KD5G pulsejet-powered targets and the KD3G and KD4G piston-powered targets, to the KD6G series of piston-powered targets. The KD6G series appears to have been the only one of the Globe targets to be built in substantial numbers. It was similar in size and configuration to the BTT series, but had a twin-fin tail. It
10602-686: The post-World War II period, Radioplane followed up the success of the OQ-2 target drone with another very successful series of piston-powered target drones, what would become known as the Basic Training Target (BTT) family (the BTT designation wasn't created until the 1980s, but is used here as a convenient way to resolve the tangle of designations), including the OQ-19/KD2R Quail and the MQM-33/MQM-36 Shelduck. The BTTs remained in service for
10716-456: The public and media. Also, the relation of UAVs to remote controlled model aircraft is unclear, UAVs may or may not include remote-controlled model aircraft. Some jurisdictions base their definition on size or weight; however, the US FAA defines any unmanned flying craft as a UAV regardless of size. A similar term is remotely piloted aerial vehicle ( RPAV ). UAVs or RPAVs can also be seen as
10830-477: The pulsejet in the fuselage and intake in the nose. It featured straight, low-mounted wings with tip tanks, and a triple-fin tail. Japan launched long distance attacks on the US Mainland using their Fu-Go unmanned balloons. They used the high-altitude jet stream and a novel ballast system to reach the northwestern US. Though intended to cause forest fires and widespread panic, their impact was not significant. In
10944-629: The rest of the 20th century. The first target drone converted to the battlefield unmanned aerial photo reconnaissance mission was a version of the MQM-33 conversion for the US Army in the mid-1950s designated the RP-71, later re-designated the MQM-57 Falconer. The US military acquired a number of other drones similar in many ways to the Radioplane drones. The Globe company built a series of targets, beginning with
11058-668: The smaller N.9) to meet Admiralty Specification N.2(a) for a carrier-based seaplane for the Royal Naval Air Service during the First World War. N.10, also known by its constructor's number F.128 was a two-bay biplane with folding wings and powered by a 260 hp (190 kW) Sunbeam Maori engine. It first flew from the Port Victoria seaplane station on the Isle of Grain , Kent on 14 September 1917. Following tests both as
11172-679: The technology that Tihanyi depicted in his 1929 patent became so influential that American UAV-producing companies still used many of its solutions even half a century later, until the mid-1980s. Subsequent British "drones" included the Airspeed Queen Wasp , the Miles Queen Martinet , and the US-supplied Curtiss Queen Seamew . After WW II these would be replaced by the jet-powered Anglo-Australian GAF Jindivik . The Soviets tested pilotless munitions-delivery in 1935-1939. The first large-scale production, purpose-built drone
11286-633: The term "DRONE" to designate radio-controlled aerial targets. From 1929 Hungarian scientist Kálmán Tihanyi worked on television guidance for defense applications, building prototypes of a camera for remotely-guided aircraft in London for the British Air Ministry , and later adapting it for the Italian Navy . In 1929, Tihanyi invented the first infrared-sensitive (night-vision) electronic television-camera for anti-aircraft defense in Britain. The solutions of
11400-529: The term RPAS has been adopted by the Canadian Government to mean "a set of configurable elements consisting of a remotely piloted aircraft, its control station, the command and control links and any other system elements required during flight operation". UAVs may be classified like any other aircraft , according to design configuration such as weight or engine type, maximum flight altitude, degree of operational autonomy, operational role, etc. According to
11514-651: The third of the Australian IIIDs, designated ANA.3 (or Australian Naval Aircraft No. 3 ), flown by Stanley Goble (later Air Vice Marshal) and Ivor McIntyre was awarded the Britannia Trophy by the Royal Aero Club for circumnavigating Australia in 44 days. The IIID remained in Australian service until 1928. Portugal ordered its first IIIDs in 1921. Its first aircraft, modified as the F.400 and named "Lusitânia",
11628-455: The two standard ones and sometimes with an enlarged rear cockpit. One carried five passengers, one in the extra cockpit and four in the rear. One three seat civilianized IIIC ( G-EBDI ) was part of a Daily News sponsored multi-aircraft round the world flight in 1922, with Norman Macmillan , W T Blake and cine-photographer G.H. Malins. The aircraft, with Macmillan and Malins aboard was finally lost between Lakhidia Char and Chittagong , but
11742-662: The unit was redesignated as the 350th Strategic Reconnaissance Squadron, 100th Strategic Reconnaissance Wing . The Squadron operated Ryan Firebees , launching them from modified D C-130A Hercules transport aircraft, normally two drones under each wing, each Hercules carrying 4 drones total. The UAVs deployed parachutes upon completing their missions and were usually recovered by helicopters which were tasked for those missions. The North Vietnamese Air Force utilized U.S. drone flights to practice their aerial combat skills, and although claiming several successful interceptions, only 6 are known to have been shot down by NVAF MiGs. But there
11856-450: The war at a cost of about 554 UAVs lost to all causes. In the words of USAF General George S. Brown , Commander, Air Force Systems Command , in 1972, "The only reason we need (UAVs) is that we don't want to needlessly expend the man in the cockpit." Later that year, General John C. Meyer , Commander in Chief, Strategic Air Command , stated, "we let the drone do the high-risk flying ...
11970-522: The wind changing after launch, most of the balloons missed their target, and some drifted back over Austrian lines and the launching ship Vulcano . The Spanish engineer Leonardo Torres Quevedo introduced a radio-based control-system called the Telekino at the Paris Academy of Science in 1903, as a way of testing airships without risking human life. Significant development of drones started in
12084-436: Was a draw back for chasing drones; one North Vietnamese MiG ran out of fuel, causing the pilots to eject, a North Vietnamese SAM shot down a NVAF MiG-17 while in "hot pursuit of a drone." While another NVAF MiG-17 shot down another MiG which got into his line of fire while chasing a drone. Between 1967 and until near the end of the U.S. involvement with the war in 1972, varied models of the 147SC Lightning Bug flew over half
12198-487: Was built in the Peenemünde Army Research Center and first tested in 1942. The V-1 was intended to target London and was massively fired, achieving more than one hundred launches a day. The V-1 was launched from a rail system to achieve the speed needed to operate its pulsejet engine and would achieve a 250 kilometers radius, at one point flying at 640 km/h. McDonnell built a pulsejet-powered target,
12312-467: Was exposed to armed drones and their lethal uses when after the September 11, 2001 attacks an American UAV killed Qaed Salim Sinan al-Harethi (aka Abu Ali al-Harithi) in a November 2002 drone strike that killed six people, including Qaed, the alleged mastermind of the 2000 USS Cole bombing . The attitude towards UAVs, which were often seen as unreliable and expensive toys, changed dramatically with
12426-577: Was immediately lost in the sea), completing the first aerial crossing of the South Atlantic , 72 days after their departure from Lisbon. The last aircraft, "Santa Cruz", is currently displayed at the Museu de Marinha , in Portugal. The IIID entered Fleet Air Arm Service in 1924, operating from shore bases, aircraft carriers and floats until replaced by the IIIF in 1930. The RAF Cape Flight used four IIIDs to carry out
12540-459: Was limited to a 4-drone attack on a beached Japanese merchant ship in the Russell Islands at the end of July followed by expenditure of 46 drones in the northern Solomon Islands . Two hits and two near-misses were scored on the stationary ship. Several of the later drones failed to reach their targets, but most were effective. The V-1 flying bomb was the first cruise missile ever built. It
12654-638: Was redesignated "MQM-40" in the early 1960s, by which time it was generally out of service. The use of drones as decoys goes back to at least the 1950s, with the Northrop Crossbow tested in such a role. The first operational decoy drone was the McDonnell Douglas " ADM-20 Quail ", which was carried by Boeing B-52 Stratofortress bombers to help them penetrate defended airspace. By the late 1950s combat aircraft were capable of Mach 2, and so faster targets had to be developed to keep pace. Northrop designed
12768-550: Was the one that flew under control on 21 March 1917. Low is known as '"father of radio guidance systems" and in 1976 Low was inducted into the International Space Hall of Fame . Alternatively, John Taylor suggested Low was the ‘Father of the Remotely Piloted Vehicle’. Soon after, on September 12, the Hewitt-Sperry Automatic Airplane , otherwise known as the "flying bomb" made its first flight, demonstrating
12882-702: Was the product of Reginald Denny . He served with the British Royal Flying Corps during World War I, and after the war, in 1919, he returned to the United States to resume his career in Hollywood. Denny was a successful leading man and between acting jobs, he pursued his interest in radio control model aircraft in the 1930s opening a shop. The shop evolved into the " Radioplane Company ". Denny believed that low-cost RC aircraft would be very useful for training anti-aircraft gunners, and in 1935 he demonstrated
12996-506: Was used for an attempt to fly across the South Atlantic and demonstrate the new aerial navigation system devised by Gago Coutinho , the navigator. The voyage started on 30 March 1922 (Flyers Day in Portugal), stopping at Las Palmas , São Vicente, Cape Verde and achieving the main navigation goal of Saint Peter and Paul Rocks , where it was lost during refuelling. The journey was finished using another two standard aircraft (the second of which
