General Dynamics F-111E Aardvark

Design of the F-111 began in the late 1950s in answer to an Air Force requirement for a supersonic low-level tactical bomber. The F-111 is the first swing-wing aircraft to enter production for the U.S. Air Force. The moveable wings allow the aircraft to perform well at both slow and high speeds making it safer and more efficient. A controversial attempt by the Department of Defense to require the design to also serve as an interceptor for the Navy failed when the aircraft proved to be unsuitable for carrier operations, but led to the development of the F-14 Tomcat. The first F-111A flew in December 1964 with the first production aircraft reaching service in 1967. The F-111E is a slightly modified and upgraded version of the original A model and was intended as an interim design while the substantially upgraded F-111D was developed. The Aardvark served in the U.S. Air Force until the mid-1990s when the last of them were retired. The last operational F-111s were retired by the Royal Australian Air Force in 2011.
