Dornier Do 24

https://en.wikipedia.org/wiki/Dornier_Do_24

The Dornier Do 24 is a 1930s German three-engine flying boat designed by the
Dornier Flugzeugwerke for maritime patrol and search and rescue. According to
Dornier records, some 12,000 people were rescued by Do 24s during its flying
career. A total of 279 were built among several factories from 1937–1945.

The Dornier Do 24 was designed to meet a Dutch navy requirement for a
replacement of the Dornier Wals being used in the Dutch East Indies, with the
Netherlands government signing a contract for six Dornier Do 24s on 3 August
1936. Two more prototypes were built for the German navy to be evaluated against
the Blohm & Voss BV 138.

The Do 24 was an all-metal parasol monoplane with a broad-beamed hull and
stabilising sponsons. Twin tails were mounted on the upswept rear of the hull,
while three wing-mounted tractor configuration engines powered the aircraft.
Fuel was carried in tanks in the sponsons and the wing centre section. Up to
1,200 kg (2,600 lb) of bombs could be carried under the aircraft's wings, while
defensive armament consisted of three gun turrets, one each in nose, dorsal and
tail positions. In early aircraft the turrets were each fitted with a machine
gun but later aircraft carried a 20 mm cannon in the dorsal turret.

Thirty-seven Dutch- and German-built Do 24s had been sent to the East Indies by
the time of the German occupation of the Netherlands in June 1940. Until the
outbreak of war, these aircraft would have flown the tri-color roundel. Later,
to avoid confusion with British or French roundels, Dutch aircraft flew a
black-bordered orange triangle insignia. A Dutch Dornier Do 24 is credited with
sinking the Japanese destroyer Shinonome on December 17, 1941 while the ship was
escorting an invasion fleet to Miri in British Borneo. On 10 January 1942 a
Dutch Dornier Do 24K spotted a Japanese invasion fleet heading for Tarakan
Island in Dutch Borneo, giving adequate warning so that all oil installations
could be destroyed before the Japanese arrived. After the Japanese invasion of
the Netherlands East Indies, six surviving Do.24s were transferred to the Royal
Australian Air Force in February 1942. They served in the RAAF through most of
1944 as transports in New Guinea, making the Do.24 one of the few aircraft
serving operationally on both sides during World War II.
