This thorough study of the history, development and service of floatplanes carried on battleships and cruisers documents a long neglected subject for the first time in over 400 photographs. From the 1920s through World War II, aircraft operating from catapults were used for spotting gunfire and scouting ahead of the fleet. Flying these planes was unique and the dramatic launching and recovery operations are covered by both photographs and text. Colors and markings are detailed and special attention has been paid to images showing catapult and ship details for both the ship and aircraft modeler. The assignment of all aircraft by type, totals, squadrons and ship is given annually from 1942 to 1949. In addition to rare photos of all of the experimental aircraft that were tested for this purpose, an addition chapter covers floatplanes used on small ships and submarine.
