In 1993, the Defense Advanced Research Projects Agency (DARPA) launched the Common Affordable Lightweight Fighter project (CALF). The project's purpose was to develop a stealth-enabled design to replace all of United States Department of Defense lighter weight fighter and attack aircraft, including the F-16 Fighting Falcon, McDonnell Douglas F/A-18 Hornet, and vertical/short takeoff / vertical landing (V/STOL) AV-8B Harrier II. Around the same time the Joint Advanced Strike Technology (JAST) project was started.[3] In 1994, the U.S. Congress ordered the two to be merged into the Joint Strike Fighter (JSF) program
Boeing's strategy for a competitive advantage was to offer substantially lower manufacturing and life-cycle costs by minimizing variations between the different JSF versions. The X-32 therefore was designed around a large one piece carbon fiber composite delta wing. The wing had a span of 9.15 meters, with a 55-degree leading edge sweep, and could hold up to 20,000 pounds (9,000 kg) of fuel. The purpose of the high sweep angle was to allow for a thick wing section to be used while still providing limited transonic aerodynamic drag, and to provide a good angle for wing-installed conformal antenna equipment. The wing would prove a challenge to fabricate.Ceiling

The North American Rockwell OV-10 Bronco is an American twin-turboprop light attack and observation aircraft.
After World War II, thousands of surplus PT-17s were auctioned off to civilians and former military pilots. Many were modified for cropdusting use.
Throughout the 1990s, a team of engineers from McDonnell Douglas’ Phantom Works developed and tested a unique stealth fighter shrowded in the secrecy of Area 51, known to most as the Bird of Prey.
