The Northrop Grumman RQ-4 Global Hawk is a high-altitude, remotely-piloted surveillance aircraft of the 1990s–2020s. It was initially designed by Ryan Aeronautical (now part of Northrop Grumman), and known as Tier II+ during development. The RQ-4 provides a broad overview and systematic surveillance using high-resolution synthetic aperture radar (SAR) and electro-optical/infrared (EO/IR) sensors with long loiter times over target areas.

The IAI Heron (Machatz-1) is a medium-altitude long-endurance unmanned aerial vehicle (UAV) developed by the Malat (UAV) division of Israel Aerospace Industries. It is capable of Medium Altitude Long Endurance (MALE) operations of up to 52 hours' duration at up to 10.5 km (35,000 ft). It has demonstrated 52 hours of continuous flight, but the effective operational maximal flight duration is less, according to payload and flight profile. An advanced version, the Heron TP, is also known as the IAI Eitan.

The launch customer for the S-100 was the UAE Army, which ordered 40 aircraft with an option for 40 more. The aircraft was ordered by three more undisclosed nations, with total orders reaching 200. The Camcopter underwent sea trials on the Indian Navy's INS Sujata (P56) during October 2007.[4] Flight testing occurred aboard a Pakistan Navy Type 21 frigate in the Arabian Sea on 16 March 2008,[5] with further naval testing on 14 April 2008 on the Spanish Guardia Civil vessel Rio Miño off Gran Canaria.[4][6]

The General Atomics MQ-9 Reaper (sometimes called Predator B) is an unmanned aerial vehicle (UAV) 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 are referred to as Remotely Piloted Vehicles/Aircraft (RPV/RPA) by the USAF to indicate their human ground controllers.[2][3] The MQ-9 is the first hunter-killer UAV designed for long-endurance, high-altitude surveillance.[4]

The Northrop Grumman X-47B is a demonstration unmanned combat aerial vehicle (UCAV) designed for aircraft carrier-based operations. Developed by the American defense technology company Northrop Grumman, the X-47 project began as part of DARPA's J-UCAS program, and subsequently became part of the United States Navy's Unmanned Combat Air System Demonstration (UCAS-D) program. The X-47B is a tailless jet-powered blended-wing-body aircraft capable of semi-autonomous operation and aerial refueling.[1]

A medium-altitude long-endurance UAV (MALE UAV) is an unmanned aerial vehicle (UAV) that flies at an altitude window of 10,000 to 30,000 feet (3,000–9,000 m) for extended durations of time, typically 24 to 48 hours.[1] This list includes both unmanned combat aerial vehicle and unmanned reconnaissance aerial vehicle. its two active demonstrators have undergone extensive flight and operational integration testing, having successfully performed a series of land- and carrier-based demonstrations
