This is the second edition of the first English language book to describe in detail the aircraft carried by Japan's extensive submarine fleet in World War Two. More than any other nation, Japan designed, built and operated aircraft launched from submarines, using them for reconnaissance and also (uniquely) for bombing and attack missions. This fascinating history of an under-published aspect of World War Two aviation warfare is illustrated with photographs, scale plans and full color illustrations, including those of the preserved Seiran.This book includes 200 photographs (many of which have not been published before) and 30 color profiles (plus top and bottom views of representative aircraft).
