Which post-WW2 combat aircraft have not been used in combat?

A couple more early limited-run jets -- the composite Ryan FR1 Fireball
and Vought F6U Pirate.

North American AJ Savage

If we're ruling out recce/weather/tanker/ELINT/ECM etc., the B66 and A3D
(although the at least the Destroyer certainly suffered combat losses in
one or more of those roles -- what about the Skywarrior?).

And I would have sworn that the FJ4/F1/AF1 Fury saw service in Vietnam,
but according to http://home.att.net/~jbaugher1/p86_24.html they were
withdrawn from active service by 1962.
