Deployed tactical nuclear weapons are now restricted to various modifications to the B-61 gravity, or free-fall, bomb. US aircraft capable of delivering this weapon are the A-4, A-6, A-7, AV-8B, F-4, F-15, F-16, F-18, F-111, and presumably the F-117 stealth fighter.
Not sure just how accurate that is being that over half of those are no longer in service and haven’t been for years. Infact, I think only the F15, F16 and F18 are still in service
