In this new, fully updated edition 2025, expert author Francis Crosby traces the development of fighters from World War I to the present day, and highlights actions in which fighters played a crucial role. The A-Z sections form an illustrated guide to over 170 fighter aircraft. The first covers aircraft from the pioneering days of air fighting in World War I through to the early jets at the end of World War II, and the second focuses on the remarkable advances of post-World War II, mainly jet, aircraft from 1945 to the present day. Specification boxes for each aircraft provide information about the plane's country of origin, first flight, power, armament, size, weight and performance. Also included is a glossary explaining aviation terms. Illustrated with 600 photographs, this is a key reference book for all aircraft enthusiasts.
