Junkers W 33 was a German-built, single-engine, passenger- and transport aircraft, in all-metal.

Development

The German aircraft manufacturing industry and aviation was laden with heavy restrictions after World War I. To go around these restrictions, the Germans started to cooperate with the Russians, and built an aircraft factory in Fili, in the Soviet Union in 1922. The Swedish company AB Flygindustri was also contracted to manufacture Junkers' designs on license in 1925. Large portions of the aircraft were constructed as knock-down-kits by Junkers in Dessau, and were later assembled in the foreign companies, where also the modifications of the military versions were made.

Junkers W 33 was constructed in 1926 as a passenger aircraft, completely built in an aluminum alloy, called duralumin. The aircraft itself was a further development of the Junkers F 13, and could carry a heavier load. It was equipped with a watercooled six-cylinder Junkers L 5 inline engine. The first flight with the W 33 took place on June 7 1926 in Germany. The first Swedish-assembled W33 was ready by May 1930, and was delivered two months later to Mitsubishi in Japan. This aircraft was used in an attempt in 1932 to fly across the Pacific Ocean to the USA, but the attempt failed and the aircraft disappeared. Neither aircraft parts nor any survivors were found although the search lasted over six months. Yet another record-breaking attempt was made with a W33 when Hermann Köhl, James Fitzmaurice (then head of the Irish Air Corps), and Ehrenfried Guenther Freiherr von Hünefeld were the first ones to cross the Atlantic Ocean from Baldonnel air base outside Dublin, Ireland, to the United States in 1928 in an aircraft named "Bremen". (The aircraft is now on display at Bremen Airport, Germany.)

The Colombian Air Force used Junkers W-33, W-34 and K-43 in the Colombia-Peru War (1932-1933).

Junkers W 33 was delivered to Sweden, where it was known as the Trp 2.
