In the German gaming magazine PC Player (issue 01/1996) U.S. Navy Fighters was named "Best Simulation in 1995".
There was an expansion pack to USNF called "Marine Fighters", which added VTOL fighters like Harrier II, Sea Harrier, and the Yak to the list of flyable planes, along with some extra controls for the VTOL engines.
The add-on is later combined with USNF to create USNF Gold.
The game was unrealistic, but really fun to play due to its great dogfights and the control players had over the game.
Many computers at the time of its release could barely run the game because of its great graphics, complete with high-res modes and full textures.
Flyable aircraft were: F-14 Tomcat, F/A-18 Hornet, A-7 Corsair, F-22 "Lightning II" (carrier capable of course), Su-33 Flanker, and F-104 Starfighter (added as a bonus plane with no real relevance).
USNF was the precursor to EA's/Jane's Advanced Tactical Fighters, USNF'97, Fighters Anthology, etc.
Custom libraries were addons made by users, which added aircraft, weapons, vehicles, etc. and some made the game more realistic.
