Carrier-based aircraft and France's . The use of catapults allows an aircraft carrier to launch large fixed-wing aircraft. For example, the U.S. Navy launches its E-2 Hawkeye AEW aircraft and C-2A Greyhound cargo aircraft with catapults. STOVL takeoffs are accomplished with "ski-jumps", instead of a catapult. STOVL use usually allows aircraft to carry a larger payload as compared to during VTOL use, while avoiding the complexity of a catapult. The best known example is the Hawker Siddeley Harrier Jump Jet, despite being capable of VTOL takeoffs, is usually operated as a STOVL aircraft to increase its fuel and weapons load. STOBAR is
Hawker Siddeley Harrier to replace the first generation of Harrier jets already in service; all the above variants of the Harrier have mainly been retired with the Harrier II taking their place in the RAF, USMC and FAA. In the 1970s the United Kingdom considered two options for replacing their existing Harriers: joining McDonnell Douglas (MDD) in developing the BAE Harrier II, or the independent development of a "Big Wing" Harrier. This proposal would have increased the wing area from , allowing for significant increases in weapons load and internal fuel reserves. The option of cooperation with MDD was chosen in 1982 over
