The F-111 is a versatile military aircraft developed by General Dynamics in the 1960s. It features a variable-sweep wing design, allowing it to adapt to different flight conditions, making it effective for both low-level penetration and high-speed flight. The aircraft was primarily used by the United States Air Force and played a significant role in various conflicts, including the Vietnam War. Equipped with advanced avionics and weapons systems, the F-111 was capable of delivering precision strikes. It served in multiple roles, including as a fighter-bomber and reconnaissance aircraft, until its retirement in the 1990s, paving the way for newer models like the F-15 and F-16.
