ww2dbaseThe D3A Navy Type 99 dive bombers were introduced to the Japanese Navy admirals in Dec 1937 after a request for such an attack aircraft in the summer of 1936. The initial tests done in Jan 1938 were rather disappointing; naval experts deemed the aircraft underpowered and unstable. It took a modification in the design for the D3A to barely win the contract over competitor Nakajima's D3N. The first major combat the D3As saw was no other than the Pearl Harbor attack that started the Pacific War. Through the successful Japanese conquest of the Pacific Ocean in the following six months, D3A dive bombers, by now code named Val by Allied airmen, became among the most dreaded sights for opposing sailors. During the Indian Ocean Raid of Apr 1942 for example, 80% of the bombload dropped by D3As against British cruisers Cornwall and Dorsetshire and carrier Hermes found their targets, causing devastation. In Jun 1942, D3As were produced with a more powerful engine, adding more power but reducing range, so many of them began carrying additional fuel tanks to make up for the difference. Later on in the war, Yokosuka D4Y Suisei dive bombers replaced them as the standard dive bombers of the Navy, and many D3As were transferred onto smaller carriers, to land-based units, or back to Japan as trainers. Some of these aircraft saw one last mission as kamikaze in the final year of the war.
