''Project E'' was an American initiative designed to provide it's Ally Great Britain with feasible nuclear material to provide The Royal Air Force with a Tactical Nuclear Deterrent and Defense. The US also provided scientific measures to help refine Great Britain's Program to include nuclear reactor and processing abilities. The primary goal of ''Project E'' would lead to the formation of the previously discussed ''V Bomber'' Squadrons. These were Britain's ''Nuclear Attack and Deterrence'' Force which composed of Jet Fighters and Bombers which would defend that Nation from Soviet (Russian) nuclear attack. ''Project E'' would continue until 1992, when Britain's Nuclear capabilities were seen as ''self-sufficient''.
