In 1985, the U.S. Air Force requested proposals for an Advanced Tactical Fighter (ATF) and selected two teams to build prototypes, one led by Lockheed and one by Northrop. The Lockheed-Boeing-General Dynamics team proposed what was designated the YF-22 Raptor which first flew in 1990. Both fighters were designed to include stealth technology. The U.S. Air Force selected the YF-22 over the Northrop-McDonnell Douglas YF-23.
