Convair Advanced Designs II: Secret Fighters, Attack Aircraft, and Unique Concepts 1929-1973 by Robert Bradley

Publisher: Crecy Publishing (December 16, 2013)

Although the Convair Aircraft Company built some of the world’s best seaplanes and bombers during World War II the company’s rise to prominence as a builder of fighters and attack aircraft did not occur until after 1945. This companion publication to Robert E Bradley’s Convair Advanced Designs: Secret Projects from San Diego, 1923-1962, covers these new aircraft types in the same detailed and comprehensive style.Previously unpublished company photographs, models, and drawings of such radical concepts as a vertical takeoff ground-attack fighter and giant eight-engine double-decker military transport combine with other futuristic designs some of which eventually evolved into production aircraft.
