Good article from Air and Space on the FB-111 and how it affected the F-14.
The F-111B was designed to defend the fleet, but only one landed aboard an aircraft carrier, the Coral Sea, in 1968, after the program was cancelled. (USS Coral Sea CVA-43 Association)
The FB-111 (later F-111G) was actually the nuke bomber version, even lengthened it was a pretty small bird to be taking all the way to Mother Russia.
