Tupolev SB aircraft was conceived as a bomber, overtaking fighters. It was natural to create a heavy fighter, designed primarily to combat the bombers. Total produced three prototypes of the SB. According to the decision of the meeting of February 14, 1934, one of them got American motors “Cyclone”, another French Hispano-Suiza, and the third was going to keep in reserve in the form of a set of units. Three days later appeared a decree of the Council of labor and defense (STO), which stated that the third prototype of SB should be equipped with the type of engine, which is better to manifest themselves on tests.

Experimental aircraft D-558-I. In late 1944 the Douglas firm received an order to develop an experimental aircraft with a turbojet engine. The main goal of this project was to obtain information about the aerodynamic loads, stability and controllability of the aircraft at transonic speeds. These data were to complement the information obtained in the course of implementation of the programme of tests of a supersonic aircraft X-1. In accordance with the specification developed by NACA (national Advisory Committee for Aeronautics) the aircraft was to take off from the aerodrome, to gain height from 6000 to 10,600 m, within 10 minutes to fly at transonic speeds and then return to the airfield.
Training U-2 aircraft – single-engine biplane of wooden construction with fixed landing gear, was designed at the factory number 1 in Moscow under the leadership of H. H. Polikarpov. His first version took off in the beginning of 1927, the Basis for the series was the second option, took to the air July 1, 1928
An Italian bomber FIAT BR.20 Cicogna. Italian aircraft FIAT BR.20 Cicogna (Italian. — AIST), created in the prewar years, engineer, Celestino Rosatelli, differed from the other two-engine bombers in service with the Italian air force. He had a successful design was completed with the most modern equipment and could carry an impressive bomb load. Combat patrol bomber began in the skies of Spain and ended with the end of world war II on the allied side of Germany, the Italian air force.
Developing the concept of training plane DH.60, John. De Havilland has created a new aircraft of the same class – DH.60T. He was distinguished by a reinforced airframe, a modified biplane gearbox and motor “Gypsy” lll (120 HP). After releasing a small series of DH.60T went into production DH.82 with the increased chord of the lower wing. The first flight of a machine called “tiger moth”, was held on 26 October 1931
HISTORY OF PS-35 (ANT-35). At the end of 1930-ies in the Soviet air force began to penetrate American airliner DC-3, launched in Khimki under designation PS-84. Later this machine became widely known as Li-2. “American” quickly moved “in the shadow” of the passenger aircraft of national design, including the Tupolev PS-35. The history of the past is very interesting. Almost all know that A. N. Tupolev managed to significantly speed up the creation of the first Soviet passenger jet Tu-104, using units of long-range bomber Tu-16. But such a trick the designer had done in the past – a shining example of this was the PS-35. The basis for it was the famous high-speed bomber SB.
Long-range bomber Il-4 (DB-DF) was established in 1940 Intended for bombing attacks in the deep rear of the enemy, DB-ZF from the first days of the war these planes were used to deter the advancing German troops, mainly in the afternoon. The solution to unusual problems without escort fighters resulted in heavy losses, but this practice did not last long. During the war the aircraft was constantly adapted to the technological capabilities of enterprises, enhance weapons, on some machines, set the autopilot.
The first flight of fighter I-301 with motor liquid cooling M-105P, created under the leadership of S. A. Lavochkin, V. P. Gorbunov and M. I. Gudkov and became the prototype of the LaGG-3 was held on 19 March 1940, Good armament (20mm cannon and 12.7 mm machine gun) together with a high speed (605 km/h) prototype machine contributed to the rapid introduction And 301 for six aircraft factories. The first production aircraft took to the air January 23, 1941
Yak-9 became the subsequent development of long-range fighter Yak-7ДИ, appeared in October 1942 and the Yak-7ДИ made two wing tank, reducing fuel capacity up to 320 kg. there were some other seemingly minor, but important differences in a battle. This version was tested successfully and were built in three factories under the designation Yak-9. Armament usually consisted of 20-mm cannon ShVAK and the UBS 12.7 mm machine gun.
Seaplane Aichi M6A Seiran. May 1945. Although Nazi Germany had already surrendered, but Japan is, however, provided the American army and Navy fierce resistance, both on land and at sea, thus causing their opponents a huge loss. Moreover, being in a critical situation, she not only conducted defensive operations, but were planning a counterattack on strategic targets on the American continent.
