Around 1990, the US Navy considered an F-14 replacement based on either the F-22 or F-23 designs, the Navy Advanced Tactical Fighter (see Aerospace Projects Review issue V3N2 for a whole lot on the Northrop NATF-23). The Lockheed NATF-22 designs seems to have never been fully nailed down, but instead was constantly in flux. But the basic idea was that it would be a navalized version of the F-22 with swing-wings akin to those of the F-14. However, the Navy gave up on the idea in 1992.

Side note: if anyone might happen to have good data on the NATF-22 (more than the stuff that showed up in magazines and such at the time), please contact me.
