TB-1 airplane (IPG-4) the world's first all-metal heavy twin-engined bomber-monoplane, the prototype for many subsequent OKB AN multiengine aircraft. Tupolev. And the story of its creation is: to perform work, held in the Special technical bureau for military inventions, It required a large aircraft, which could be used for dropping bombs, min and torpedoes.

Experience of creating such large machines in our country did not yet exist, and we decided to order the British, known firm 'Handley Page ". The British asked 500 thousand. rubles, year and a half to design and build prototype. The services of the company refused: and expensive, and long. 9 July 1924 g. TsAGI received a proposal to develop a baseline for such aircraft. the necessary calculations have been carried out, which turned, that on their own to build a bomber will be cheaper and faster. A. N. Tupolev, namely, he was assigned to design, He promised to build an airplane for 9 months and 200 thousand. rubles.
designing started 11 November 1924 g. The new aircraft to be fitted with two engines "Jupiter" company "Bristol", but in the course of designing switched to more powerful "Lion" on 450 HP. Already in the process of designing military showed great interest in the car. In April 1925 g. they sent to TsAGI their technical requirements for bomber. Air Force requirements for the ANT-4 decided to consider when building a "doubler". Construction of the aircraft finished in time, exactly nine months. 25 November 1925 g. it took a special commission. The next day, the pilot AI. Tomaszewski picked up the plane in the air. Tests completed by the summer 1926 city, and 10 July car passed to the customer.
In February 1928 g. the second instance of the plane ANT-4 was built with all the military requirements. Compared with the prior art to "doubler" sweep and reduced wing area, We changed the nose of the fuselage, installed machine guns and weapons Bomber. bomber TB-1 testing began in July, they conducted the test pilot MM. thunders. Serial production of TB-1 was decided even after the test the first prototype. Serial machines were built with engines M-17 (licensed BMW-IV), they were produced in small series, and before the 1932 g. Was built 216 copies, including 66 machines float variant for the Navy aviation. The first TB-1 entered service in the Air Force 1929 g. and were in service until 1936 city, and some of them before the start of World War II.
The EDO, besides main variant MDR-1, several modifications have been developed. ANT-4 aircraft several outstanding flights were performed, Among the most famous was the flight of the aircraft, "Land of the Soviets". FROM 23 August 1 November was made a flight on the route Moscow - New York crew of SA. Shestakova, F.E. Bolotov, BV. Sterligov and DV. Fufa. for 141 no 45 minutes flying time aircraft flew 21 242 km - it was the first flight in the history of the Soviet Union in the US. By plane several world records have been set.
Over the years, the TB-1 performed a variety of tests, including take-off from the starting solid propellant boosters, practicing torpedo bombing techniques, function air tanker. TB-1 in March 1934 g. pilot AV. Liapidevskii Chelyuskinites participated in the rescue and brought out of the camp all the women and children. After the cancellation of the Air Force planes were transferred to Aeroflot (with the name of G-1), shot with them all the weapons, and they have long been used as a transport. Freight lines machines had huge raid, several times repaired and used up to a limit. One copy of the restored T-1 is located at the Ulyanovsk Civil Aviation Museum.
