In 1960, DoD also combined a USAF requirement for a new fighter-bomber to ostensibly replace TAC's F-105 fighter-bombers with a USN need for a new carrier-based 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 variable-geometry wing Tactical Fighter Experimental (TFX) design eventually winning out. Designated as the F-111, the Navy version was known as the F-111B and the USAF version the F-111A, with the first flight of the F-111A taking place in December 1964 and the first production models delivered to the USAF in 1967. Additional variants such as the FB-111A for SAC and the F-111E, F-111F and EF-111A for TAC and USAFE, plus the F-111K for the RAAF followed. Meanwhile, the Navy's F-111B program was canceled after five examples when it became apparent that its performance characteristics were unsuitable for an aircraft-carrier based fighter and interceptor, with many of its design features and systems being incorporated into the successful Grumman F-14 Tomcat. In all, 562 F-111s of all series were built.
