An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any 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.
Unmanned Aerial Vehicles (UAVs) include both autonomous drones and remotely piloted vehicles (RPVs). A UAV is capable of controlled, sustained level flight and is powered by a jet, reciprocating, or electric engine. In the twenty-first century, technology reached a point of sophistication that the UAV is now being given a greatly expanded role in many areas of aviation.
The Elbit Hermes 450 is an Israeli medium-sized multi-payload unmanned aerial vehicle (UAV) designed for tactical long endurance missions. It has an endurance of over 20 hours, with a primary mission of reconnaissance, surveillance and communications relay. Payload options include electro-optical/infrared sensors, communications and electronic intelligence, synthetic-aperture radar/ground-moving target indication, electronic warfare, and hyperspectral sensors.
The Elbit Systems Skylark I and Skylark II are miniature UAVs developed by Elbit Systems. Initial models of the Skylark entered service in 2008.
The Elbit Systems Hermes 900 Kochav ("Star") is an Israeli medium-size, multi-payload, medium-altitude long-endurance unmanned aerial vehicle (UAV) designed for tactical missions. It is a successor to the Hermes 450 series of drones, one of the most widely used military drones in the world.
The UMS Skeldar V-200 is a medium-range VTOL UAV developed by the Swedish aerospace company Saab. The Skeldar can be used for surveillance, intelligence gathering, light cargo transportation, and electronic warfare.
ZALA Aero Group is a Russian company specialising in unmanned aerial vehicle (UAV) development, located in Izhevsk, Russia. ZALA Aero has provided UAV systems for several sectors of the Russian government, including the Ministry of Defence, and has also won contracts to supply UAVs to foreign countries. The company's in-house design and production projects include a variety of systems related to UAV design, manufacture and operation, including autopilots, airframes, mechanical and pneumatic catapults, launchers, payloads and communication technologies. ZALA Aero is the only Russian company producing unmanned helicopters, portable anti-drone EW systems and a VTOL drone.
The AeroVironment RQ-20 Puma is an American unmanned aircraft system which is small, battery powered, and hand-launched. Its primary mission is surveillance and intelligence gathering using an electro-optical and infrared camera. It is produced by AeroVironment.
The DRDO Netra is an Indian, light-weight, autonomous UAV for surveillance and reconnaissance operations. It has been jointly developed by the Research and Development Establishment (R&DE), and IdeaForge, a Mumbai-based private firm.
Drone journalism is the use of drones, or unmanned aircraft systems (UAS), for journalistic purposes. According to the Federal Aviation Administration, "an unmanned aircraft is a device that is used, or is intended to be used, for flight in the air with no onboard pilot".
3DR is an American company located in Berkeley, California that produces enterprise drone software for construction, engineering and mining firms, as well as government agencies.
Unmanned aerial vehicles (UAVs) have been used for domestic police work in various countries around the world since the mid-2000s. Their appeal comes from their small size, lack of crew, and lower cost compared to police helicopters. UAVs may be used for search and rescue operations, aerial patrols, and other roles that are usually served by crewed police aircraft. UAVs can be powerful surveillance tools by carrying camera systems capable of license plate scanning and thermal imaging, as well as radio equipment and other sensors. While a vast majority of law enforcement UAVs are unarmed, documents obtained by digital rights group Electronic Frontier Foundation indicated the U.S. Customs and Border Protection would consider arming their UAVs with "non-lethal weapons designed to immobilize" targets.
The Shooting Star is a quadcopter drone designed for light shows by Intel. It is constructed of Styrofoam and lightweight plastics; and it has built-in light-emitting diodes (LEDs) for display purposes. Large numbers of Shooting Star drones can be controlled by a single computer and operator that can create more than four billion color combinations from the built-in LEDs, with the system's algorithms controlling the choreography and optimizing the flight paths. In 2022, Intel sold the division to Nova Sky Stories.
A loitering munition is a kind of aerial weapon with a built-in munition (warhead), which can loiter around the target area until a target is located; it then attacks 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 the target area and also allow more selective targeting as the attack can be changed mid-flight or aborted.
Baykar is a private Turkish defence company specialising in UAVs, C4I and artificial intelligence.
The Albatross(Chinese: 銳鳶; pinyin: Ruì yuān,“Sharp Kite”), also known as the Chung Xiang II, is a medium unmanned aerial vehicle made by National Chung-Shan Institute of Science and Technology. It is in service with the Republic of China Navy.
