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
304-399: A suicide drone , kamikaze drone , or exploding drone , is a kind of aerial weapon with a built-in warhead that is typically designed to loiter around a target area until a target is located, then attack the target by crashing into it. Loitering munitions enable faster reaction times against hidden targets that emerge for short periods without placing high-value platforms near

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
456-501: A backpack. Pocket-size jammers for soldiers were also developed. As of June 2023 Ukraine was losing 5-10,000 drones a month, or 160 per day, according to Ukrainian soldiers. This has led to Russia creating wire guided FPV drones, similar to a wire-guided missile or even wire-guided torpedoes. One drone captured by Ukrainian forces had 10.813 km of fibre optic cable. Such guidance makes the link between operators and FPV drone immune to jamming. It also allows for much faster updates from

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,
608-574: 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

Loitering weapons first emerged in the 1980s for use in the Suppression of Enemy Air Defenses (SEAD) role against surface-to-air missiles (SAMs) and were deployed in that role with a number of military forces in the 1990s. Starting in
1216-793: A modification. Loitering munitions fit in the niche between cruise missiles and unmanned combat aerial vehicles (UCAVs). The following table compares similar size-class cruise missiles, loitering munitions, and UCAVS: Whereas some cruise missiles, such as the Block IV Tomahawk , have the ability to loiter and have some sensory and remote control features, their primary mission is typically strike and not target acquisition. Cruise missiles, as their name implies, are optimized for long-range flight at constant speed both in terms of propulsion systems and wings or lifting body design. They are often unable to loiter at slow fuel-efficient speeds which significantly reduces potential loiter time even when
1292-436: A parallel increase in the use of drones for consumer and general aviation activities. As of 2021, quadcopter drones exemplify the widespread popularity of hobby radio-controlled aircraft and toys, however the use of UAVs in commercial and general aviation is limited by a lack of autonomy and by new regulatory environments which require line-of-sight contact with the pilot. In 2020, a Kargu 2 drone hunted down and attacked
