The Yokosuka B4Y, (Navy Type 96 Carrier Attack Bomber), is an aircraft carrier, and torpedo bomber was used by the Imperial Japanese Navy Air Service from 1936 to what year?
Aircraft carrier An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Aircraft carriers are expensive to build and are critical assets. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighter planes, strike aircraft, helicopters, and other types of aircraft. While it is possible to launch heavier aircraft such as fixed-wing gunships and bombers (it has been done) from aircraft carriers, it is virtually impossible to land them.
Kawasaki Ka 87 The Dornier N was a bomber aircraft designed in Germany in the 1920s for production in Japan. Production of 28 aircraft started in Japan in 1927, as the Kawasaki Ka 87 (also known as the Type 87 Night Bomber). Designed and built as a landplane, its layout was strongly reminiscent of the Dornier flying boats of the same period; a parasol-wing, strut-braced monoplane with two engines, mounted in a push-pull nacelle above the wing. Some of the 28 examples built saw action in Manchuria in 1931.
