History


The joint Fokker-Republic Project Division at Schiphol was headed by Alexander Wadkowsky of Republic Aviation. This projectteam started to work on the NATO BMR-3 requirement. This requirement asked for a tactical strike fighter with V/STOL capacity. Right from the start there was a lot of rivalry between the employees from both companies. This rivalry was both nationalistic as well as between both companies. Ultimately this led to the end of the co-operation of both companies.


Airframe


wing: A variable-geometry involving a slender-delta fixed wing combined with a flush-folding variable-sweep portion.
fuselage: Equipped with internal weapons bay.
tail: No horizontal tail, conventional vertical tail.
landing gear: Retractable.


Powerplant


The proposed engine for the Alliance was the vectored-thrust Bristol Siddeley BS.100/3 with a thrust potential of 17500 kg (38500 lbs). This engine had plenum chamber burning in the two forward swiveling nozzles. It was calculated that the Vertical Take Off (VTO) weight with 2270 kg (5000 lbs) useful military load would be approximatly 15875 kg (35000 lbs) while Short Take Off (STO) weight could rise to 20,400 kg (45000 lbs) or more.
