This long-range aircraft became best known (in the USA - A.S.) by a record flight from Moscow to San Jacinto in California, over the pole: 10148km. The ANT-25 was also used to set a closed-circuit flight record with a flight of 56h and 20min. As might be expected, the ANT-25 was a clean monoplane with an extremely long wingspan: 34.98m.

Decision of building this aircraft took place on April 8 1932. Main goal - leap forward in the long range aviation field. P.O.Sukhoj was put in charge for design and assembly of the aircraft. V.M.Petlyakov team - airdynamic and major calculations. V.N.Belyayev - major dimensions and load distribution; Nekrasov - tail section; T.P.Saprykin - landing gear; Powerplant - brigades N°2 and brigades N°8.

Construction began on June 1, 1932.
