Sikorsky Alexander Nevsky

The Sikorsky Alexander Nevsky ( _ru. Александр Невский) was the only Russian four-engine bomber-biplane of its kind, designed and built by Igor Sikorsky in the late 1916. It was named after a Russian prince Alexander Nevsky.

80% of the "Alexander Nevsky"’s fuselage was made of armored steel and duralumin. Its engines had a coarse pitch of the propeller for high speed flight, which, according to calculations, would allow the airplane to reach the speed of 250 km/h. Due to this feature, Sikorsky designed the lower pair of wings at a 12% angle of attack in order to avoid the increase of a take-off run (see Propeller for details). The "Alexander Nevsky" had no corrugated surfaces and was equipped with machine guns, semi-automatic guns, recoilless guns, rockets and bombs.

However, the "Alexander Nevsky"’s fate was to take off only once for a test flight with a 1.5-ton load onboard. Sikorsky wanted to make sure its speed corresponded to his initial calculations. On January 4, 1917, Sikorsky presented the "Alexander Nevsky"’s design to Tsar Nicholas II, reportedly saying: "Your Highness, we’re going to win the war with this plane". The tsar approved the design.

However, the "Alexander Nevsky" bomber was never put in serial production due to the events preceding and following the October Revolution and Sikorsky’s emigration to the United States of America in 1919.
