| This rather unknown Japanese
carrier borne dive-bomber was developed in the mid thirties on behalf of
the Japanese Naval Command. Mitshubishi, Nakajima and Aichi were involved
in the project. Soon two of these firms withdrew and Aichi went on on its
own. In 1937 Aichi sent a team of designers to Germany to get new ideas,
especially from Heinkel. Thence the characteristic shape of the wings and
tail of this aircraft. In 1938 Aishi got a contract and soon the prototype
made its first flight. It was an all-metal twoseater monoplane with
a span of 14.36m and a length of 10.19m. The prototype was powered by a
1000hp Kinsel 44 radial engine, which gave the aircraft a top speed of
382km/h. Its range (1.820km) was remarkable for those days. It turned out,
however, that the aircraft needed considerable improvements, but soon after in
1939 the first models were introduced, the D3A1, code-named "Val" by the
Allies became a dangerous opponent that was famous for its bombing
accuracy. It used to be loaded with one 250kg and two 30-60 kg bombs, and
armed with two fixed front-firing 77mm machineguns aa well as a flexible one fired by
the radio operator. The aircraft participated in the surprise attack on Pearl Harbor on
December 7,
1941. On April 5, 1942 the "Vals" succeeded in sinking some
cruisers like the "Dorsetshire" and "Cornwall". In the region of Ceylon "Vals" sank the British aircraft carrier "Hermes" ,which had no aircraft on board other than two "Swordfish", in for repair. This ship was the only British aircraft carrier to be sunk by aircraft in WW II. After the heavy losses suffered by the Japanese at the Battle of Midway, the remaining "Vals" were transferred to land-base squadrons and used there for training purposes. When the US forces retook the Philippines, the "Vals" came to action again, to be used for kamikaze attacks. The result was that of the total of 1.495 of all types built, there were hardly any left at the end of the war.
Deze niet al te bekende marine
duikbommenwerper werd ontwikkeld in het midden van de dertiger jaren ten
behoeve van het Japanse Marine opperbevel. Mitsubishi, Nakajima en Aichi
waren bij dit project betrokken. Al gauw trokken twee van deze firma's
zich terug en Aichi ging alleen verder. In 1937 stuurde Aichi een groep
ontwerpers naar Duitsland om nieuwe ideeën te verzamelen, vooral van Heinkel.
Vandaar de karakteristieke vorm van de vleugels en de staart. |
