The versatile "swing wing" F-111, unofficially named the "Aardvark" until its retirement ceremony on July 27, 1996, when the name was made official, entered the USAF inventory in 1967. The F-111 could exceed twice the speed of sound (Mach 2) by sweeping its wings rearward while in flight. The wings are swept forward for takeoffs, landings or slow speed flight.
Originally known as the TFX (Tactical Fighter "X"), the F-111 was conceived to meet a USAF requirement for a new tactical fighter-bomber. In 1960 the Department of Defense combined the USAF's requirement with a Navy need for a new air superiority fighter, then launched a competition among aircraft manufacturers for the final design. In 1962 General Dynamics and Boeing were selected as finalists with the General Dynamics TFX design eventually winning out. The Navy version was known as the F-111B and the USAF version the F-111A. The first flight of the F-111A took place in December 1964, and the first production models were delivered to the USAF in 1967. Meanwhile, the Navy's F-111B program was canceled. In all, 562 F-111s of all series were built; 159 of them were preproduction and production F-111As.
The National Museum of the United States Air Force has an F-111A on display.

- Four F-111Cs were converted to RF-111C for RAAF.
- One FB-111A crashed during acceptance testing and was never delivered to the USAF.
- Two US Navy F-111Bs were under construction when the program was canceled.
- Two nearly complete RAF F-111Ks were turned over to the USAF as YF-111A and completed as FB-111A S/N 67-149/150.
