The F-14ADF was one of the rarest Tomcat variants produced with a total of 43 built, it was used by the OADF and the Air National Guard as a long-range 'patrol fighter' which freed up the F-106s and early F-16s for point defense interception. Much of the avionics are the same as the Navy's F-14A, but some parts have been either omitted entirely or stripped down to the bare essentials to improve speed and range. When later-model F-15s began to trickle down from frontline units to the Air National Guard the F-14ADF began being phased out. Most are in either museums or storage however two remain airworthy, one kept in the manufacturer's collection and displayed at the National Museum of Naval Aviation in Stockdale and the other as part of the OADF's Heritage Flight program
