  • Late in World War II Japan adopted the practice of giving names to their aircraft. The Suiseu (or "Comet") was the fastest carrier-based dive bomber of WWII. This was accomplished at the peril of the crew as the aircraft had no armor, unprotected fuel tanks, and light armament. Given the Allied code name "Judy," the Suiseu also saw duty as a reconnaissance aircraft, a night fighter, a kamikaze craft.
  • As early as 1937 the Imperial Japanese Navy saw that a replacement for the Aichi D3A dive bomber was needed. Yokosuka Naval Air Arsenal was asked to produce a new dive bomber with a range of 1,380 miles and a 550-pound payload, capable of a top speed of 320 miles per hour. Yokosuka chose an inline engine, the Aichi Atsuka which was a licensed copy of the Daimler-Benz DB 600. The prototype flew in November 1940. Although it was fast and handled well, the airplane's engine suffered from continual problems which required almost two additional years to resolve. Some pre-production models did go into active service in 1942 but were employed as high-speed reconnaissance craft and were lost with the sinking of the Soryu at Midway in June of 1942.
  • Late models of the D4Y were introduced with radial engines which proved more reliable. A total of 2,319 D4Ys were built during the war, the bulk of which were destroyed by the masses of U. S. fighters sent up to intercept them before reaching their intended targets. Although the D4Ys performed well, their minimal protective armor and lack of self-sealing fuel tanks made them vulnerable to attack.
  • Planes of Fame’s D4Y3 Suiseu is not a flying aircraft, but upon engine start, is taxiable.
