4 fly high1/1/2023 Air Force plans to retire its Global Hawks in 2027. Navy has developed the Global Hawk into the MQ-4C Triton maritime surveillance platform. By 2001, this had risen to US$60.9 million, and then to $131.4 million (flyaway cost) in 2013. The initial flyaway cost of each of the first 10 aircraft was US$10 million in 1994. According to the USAF, the superior surveillance capabilities of the aircraft allow more precise weapons targeting and better protection of friendly forces.Ĭost overruns led to the original plan to acquire 63 aircraft being cut to 45, and to a 2013 proposal to mothball the 21 Block 30 signals intelligence variants. It is used as a high-altitude long endurance (HALE) platform covering the spectrum of intelligence collection capability to support forces in worldwide military operations. The Global Hawk is operated by the United States Air Force (USAF). It can survey as much as 40,000 square miles (100,000 km 2) of terrain per day, an area the size of South Korea or Iceland. 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. It was initially designed by Ryan Aeronautical (now part of Northrop Grumman), and known as Tier II+ during development. The Northrop Grumman RQ-4 Global Hawk is a high-altitude, remotely-piloted surveillance aircraft of the 1990s–2020s.
