caption_attribution_description: English: This restored example of a Yokosuka D4Y1 dive bomber (serial number 4316) likely served in the Pacific Theater of WWII before being abandoned in the Yap Islands in the Western Pacific. The wreck was rediscovered by Endo Nobuhiko in 1972 in the jungle alongside a former airfield in the Yap Islands. The Nippon Television Network Corporation helped to return the aircraft to Japan in 1980. It was restored at the Kisarazu Ground Self Defense Forces Base under the leadership of aircraft researcher Tanaka Shoichi. The completed aircraft was dedicated to the Yūshūkan War Museum at the Yasukuni Shrine on April 5, 1981. The aircraft currently resides in the large first floor exhibit room at the Yūshūkan.
context_page_description: The Yokosuka D4Y Suisei is a two-seat carrier-based dive bomber developed by the Yokosuka Naval Air Technical Arsenal and operated by the Imperial Japanese Navy from 1942 to 1945 during World War II. Development of the aircraft began in 1938. The first D4Y1 was complete in November 1940 and made its maiden flight at Yokosuka the following month.
  While the aircraft was originally conceived as a dive bomber, the D4Y was used in other roles including reconnaissance, night fighter and special attack. It made its combat debut as a reconnaissance aircraft when two pre-production D4Y1-Cs embarked aboard the Sōryū to take part in the Battle of Midway in 1942. It was not until March 1943 that it was accepted for use as a dive bomber. The early D4Y1 and D4Y2 featured the liquid-cooled Aichi Atsuta engine, a licensed version of the German Daimler-Benz DB 601, while the later D4Y3 and D4Y4 featured the Mitsubishi MK8P Kinsei radial engine.
  Like many other Japanese aircraft of the time, the D4Y lacked armor and self-sealing fuel tanks and it was not until the final variant, the D4Y4, that the aircraft was given bulletproof glass and armor protection for the crew and fuel tanks.

  An engineless D4Y1 was recovered from Babo Airfield, Indonesia in 1991. It was acquired and restored to non-flying status by the Planes of Fame Air Museum in Chino, California. It was restored to represent a radial engined D4Y3, using an American Pratt & Whitney R-1830 engine. The engine is in running condition and can be started to demonstrate ground running and taxiing of the aircraft.
