High-altitude long endurance (HALE) military drones can fly above 60,000 ft (18,000 m) over 32 hours, while civil HAPS are radio stations at an altitude of 20 to 50 km above waypoints, for weeks. High-altitude, long endurance flight has been studied since at least 1983, and demonstrator programs since 1994.
The BAE Systems Persistent High Altitude Solar Aircraft (PHASA-35) is a High-Altitude Long Endurance (HALE) unmanned aerial vehicle (UAV) developed by BAE Systems in collaboration with Prismatic. Designed as a cheaper alternative to satellites, the aircraft can be used for surveillance , border control , communications and disaster relief with ...
The Guizhou WZ-7 Soaring Dragon (Chinese: 无侦-7 翔龙; pinyin: Wú zhēn-qī Xiáng Lóng) is a high-altitude long endurance unmanned aerial vehicle (UAV) from the People's Republic of China. [1] [3] The aircraft features a unique joined-wing design. [3]
The Northrop Grumman MQ-4C Triton is an American high-altitude long endurance unmanned aerial vehicle (UAV) developed for and flown by the United States Navy and Royal Australian Air Force as a surveillance aircraft. Together with its associated ground control station, it is an unmanned aircraft system (UAS).
The MQ-9 is the first hunter-killer UAV designed for long-endurance, high-altitude surveillance. [4] In 2006, Chief of Staff of the United States Air Force General T. Michael Moseley said: "We've moved from using UAVs primarily in intelligence, surveillance, and reconnaissance roles before Operation Iraqi Freedom , to a true hunter-killer role ...
The Northrop Grumman RQ-4 Global Hawk is a high-altitude, remotely-piloted surveillance aircraft introduced in 2001. It was initially designed by Ryan Aeronautical (now part of Northrop Grumman), and known as Tier II+ during development.
The Boeing Phantom Eye is a high altitude, long endurance (HALE) liquid hydrogen-powered [1] unmanned aerial vehicle developed by Boeing Phantom Works. [2] The aircraft was Boeing's proposal to meet the demand from the US military for unmanned drones designed to provide advanced intelligence and reconnaissance work, driven by the combat conditions in Afghanistan in particular. [3]
WZ-8 is a supersonic-hypersonic, remotely operated, high-altitude reconnaissance vehicle. The aircraft bears some superficial resemblance to the DF-ZF hypersonic glide vehicle mounted onboard DF-17 medium-range ballistic missile and the American Lockheed D-21 reconnaissance drone, [ 5 ] albeit different in overall dimensions, propulsions, and ...
