The Heinkel He 59 was a German military aircraft designed in 1930 resulting from a requirement for a torpedo bomber and reconnaissance warplane able to operate with equal facility on wheeled landing gear or twin-floats.

[edit] Development
In 1930, Ernst Heinkel began developing an aircraft for the German Navy. To conceal the true military intentions, the aircraft was officially a civil aircraft. The He 59B landplane prototype was the first to fly, an event that took place in September 1931,[1] but it was the He 59A floatplane prototype that paved the way for the He 59B initial production model, of which 142 were delivered in three variants. The Heinkel He 59 was a pleasant aircraft to fly; deficiencies noted were the weak engine the limited range, the small load capability and insufficient armament.
The aircraft was of a mixed-material construction. The wings were made of a two-beam wooden frame, where the front was covered with plywood and the rest of the wing was covered with fabric. The box-shaped fuselage had a fabric covered steel frame. The tail section was covered with lightweight metal sheets.
The keels of the floats were used as fuel tanks - each one holding 900 liters of fuel. Together with the internal fuel tank the aircraft could hold a total of 2,700 liters of fuel. Two extra fuel tanks could also be placed in the bomb bay, bringing the total fuel capacity up to 3,200 liters. The propeller was fixed-pitch with four blades.
[edit] Operations
During the first months of World War II, the He 59 was used as a torpedo- and minelaying aircraft. Between 1940 and 1941 the aircraft was used as a reconnaissance aircraft, and in 1941-42 as a transport, SAR, and training aircraft. The trainer models survived slightly longer in service than operational models, but all had been retired or destroyed by 1944. Some aircraft were operated by the Condor Legion in Spain during the Spanish Civil War in 1936 as coastal reconnaissance and torpedo floatplanes.
The Ilmavoimat (Finnish Air Force) rented four aircraft from Germany in August 1943. These were used to ferry long range reconnaissance patrols behind enemy lines. They were returned to Germany four months later.
