I've got a couple of new ones ready:
This is kind of a "What-if" the Skywarrior had been kept in service along the B-52 and upgraded with TF-33 turbofans and new electronics.
Douglas - A-3H Skywarrior
Never-were:
Lockheed Martin - F-24N Sea Raptor
Northrop - YA-9A
Real life:
Sukhoi - Su-34 Fullback
Douglas/Basler - AC-47T Fantasma
Douglas/Conroy - Tri-Turbo Three
Boeing - 747SP Shahin
Lockheed - D-21B
Westland - Lynx HAS.3
