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.
Type 93 torpedo The Type 93 (九三式魚雷 , designated for Imperial Japanese calendar year 2593) was a 61 cm -diameter torpedo of the Imperial Japanese Navy (IJN), launched from surface ships. It is commonly referred to as the Long Lance by most modern English-language naval historians, a nickname given it after the war by Samuel Eliot Morison, the chief historian of the U.S. Navy, who spent much of the war in the Pacific Theater. In Japanese references, the term "Sanso gyorai" (酸素魚雷 , lit. "oxygen torpedo") is also used, in reference to its propulsion system. It was the most advanced naval torpedo in the world at the time.
