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 RQ-3 DarkStar was designed as a "high-altitude endurance UAV", and incorporated stealth aircraft technology [2] [3] to make it difficult to detect, which allowed it to operate within heavily defended airspace, unlike the Northrop Grumman RQ-4 Global Hawk, which is unable to operate except under conditions of air supremacy. The DarkStar was ...
The WZ-7 entered service with the People's Liberation Army Air Force in 2018 [1] and a number were deployed to the Tibet Autonomous Region, Hainan Island, and Yishuntun Airbase near North Korea. [13] On 24 July 2019, a WZ-7 shadowed the American Ticonderoga-class cruiser USS Antietam as she transited the Taiwan Strait. [14]
Journalists have noted design similarities between the RQ-170 and previous stealth and UAV programs such as the Lockheed Martin RQ-3 DarkStar and Polecat. [3] [4] An Air Force official said, "It's the same concept as [the RQ-3] DarkStar, it's stealthy, and it uses the same apertures and data links, only it's bigger."
Lower cost EO/IR and RF sensors are possible due to lower operating altitudes that do not require large optics or high-power RF. It can fly for over 80 hours while carrying over 400 lb (180 kg) of payload and it has a wingspan of over 80 ft (24 m). [5] [4] [6] Endurance allows these sensors to cover areas with fewer aircraft.

A high altitude platform can provide observation or communication services. A high-altitude platform station (HAPS, which can also mean high-altitude pseudo-satellite or high-altitude platform systems), also known as atmospheric satellite, is a long endurance, high altitude aircraft able to offer observation or communication services similarly to artificial satellites.
[3] NASA Centurion – The Centurion was an expansion of the Pathfinder concept, designed to achieve the ERAST Program goal of sustained flight at 100,000 feet (30,000 m) altitude. [3] NASA Helios Prototype – Derived from the Centurion, this solar cell and fuel cell powered UAV set a world record for flight at 96,863 feet (29,524 m). It was ...
The General Atomics MQ-9 Reaper (sometimes called Predator B) is an unmanned aerial vehicle (UAV, one component of an unmanned aircraft system (UAS)) capable of remotely controlled or autonomous flight operations, developed by General Atomics Aeronautical Systems (GA-ASI) primarily for the United States Air Force (USAF). The MQ-9 and other UAVs ...
