This issue presents a highly detailed overview of the North American FJ-5 fighter, a proposal for a navalized derivative of the F-107A prepared for BuAer on July 6, 1955. With its dorsal inlet and sleek aerodynamics, the FJ-5 was among the more unusual and exciting naval fighter proposals of the 1950's. This monograph covers the prototype, basic (production), supersonic reconnaissance, and rocket-boosted interceptor variants of the design. It is illustrated with 5 wind tunnel model photos and 28 drawings, the majority of which are incredibly detailed and provide ample reference for those wishing to create an accurate model or illustration of this radical jet fighter. The accompanying text is based on official North American reports submitted with the proposal and covers the type in exhaustive detail. A must for enthusiasts of naval aviation and unrealized aircraft projects!
