Although there is no evidence to suggest that nuclear material was ever present at USNF Brawdy, the shroud of secrecy that enveloped the facility meant the Welsh "Area 51" was the target of several antinuclear protests during the 1980s.
Not all believed the Americans were unwelcome: the local Western Telegraph condemned the protesters as unrepresentative of local feeling and for not recognising that USNF Brawdy was a member of a regional defence establishment that was "a vital part of the economy of West Wales".
And it is in the realm of economics that the positive embrace of USNF Brawdy can best be explained.
Little wonder that when it was announced USNF Brawdy would close heated debate resurfaced over the economic plight of the region in a manner similar to that of 1970-71.
In addition, USNF 97's Vietnam missions provide players with four new Vietnam era aircraft: the F-4 Phantom, F-8 Crusader, MiG-17 and MiG-21.
Throughout different USNF missions, the player can engage in anything from close quarters dogfighting, to bombing enemy warships, to providing cover for a squadron of bombers.
With the addition of the Vietnam era missions and aircraft, USNF `97 now provides players with more than 35 years of realistic Naval air combat and 110 missions which includes sorties and aircraft from the earlier version of USNF and its expansion disk, Marine Fighters.
