In February 1941 Aviatsionny corps of the U.S. army (the predecessor of the air force, U.S. army) became interested in the possibility of using gliders in the landing and transportation operations. As a result, by March 1941, developed the preliminary requirements for two types of gliders for the transport of eight and 15 people. These requirements sent to eleven firms, but only four of them said that they are ready to start work. It was “the Frankfort, sailplan company”, “Waco aircraft company of Troy”, “Bowles, sailplan incorporated and the St. Louis aircraft Corporation”. Other refused to participate in the contest, being involved in the implementation of other military orders, or citing the lack of necessary capacity or experience. To the stage of construction of prototypes of the gliders made it two companies.

After Sukhoi in an unspoken competition to build aircraft of the battlefield joined OKB S. V. Ilyushin. The main difference between the Il-102, su-25 table a second cockpit for the gunner. The aircraft has ejection seats K-36L pilot and K-36L-102 from air gunner. The main landing gear retracted on the fairings under the wing.
The MiG-27 with a laser sighting system “Kyra” based on fighter-bomber MiG-23БК. In contrast to the predecessor, the air intakes have become unregulated. The first flight took place in 1975, the MiG-27K was one of the first carriers of high-precision weapons of missile of class “air — ground” with a television (KH-29T) and laser (KH-29L, KH-25ML) targeting systems, as well as corrected bombs KAB-500L and KAB-500KR. To combat enemy radar intended for the KH-27PS (X-25МП). 
The history of the MiG-15 began after the Soviet trade representatives in 1946, Britain was able to purchase from the company a Rolls-Royce turbojet engine the most advanced of its time Derwent 5 with a thrust of 1,590 kg, Nene I with a thrust of 2040 kg and Nene II with traction 2270 kg. In the USSR, these engines received the designation RD-500, RD-45 and RD-45F, respectively. After that, it became possible to create a fighter with a flight speed of about 1000 km/h and a ceiling in excess of 13 000 m.
The development of the fighter began in 1933 under the designation TSKB-12. 30 December of the same year, V. P. Chkalov tested the machine with the engine M-22 in flight. During the tests achieved speed 359 km/h. the First production aircraft with two ShKAS machine guns, built at factory No. 21, the customer has got in early 1935 Later the fighter was produced with the engine M-25, M-62 and M-63, bringing its speed up to 470 km/h was Improved and weapons of a fighter.
French carrier-based aircraft BREGUET Br.1050 Alize. The need for double decked multi-role aircraft, capable of reconnaissance, and search and destruction of submarines, came the Navy of France with the deployment of the construction of new aircraft carriers. The order for the development of such aircraft placed on firm Breguet, and such a choice of the contractor was not accidental. In 1946 — 1952 Breguet has worked to develop a plane Breguet Br.960 Vultur and its anti-submarine variant VG.962 AM. It is quite logical that the new aircraft began to design on the basis of tested machines.
The biplane I-15 upper wing type “Chaika” was a further development of fighter I-5. The first flight of an aircraft equipped with the engine SGR-1820 F-Z of the company “Wright-Cyclone”, performed by V. Chkalov in 1934, First production vehicles were completed with 480-horsepower engine, M-22, and since 1937 — the M-25 takeoff power 630 HP, the Aircraft was constantly improved. His first option was the I-15bis. different upper wing, located on the scheme parasol.
Four-passenger aircraft Il-18 was designed at OKB Ilyushin in 1956 4 July 1957 the prototype it with TVD NK-4 first took to the sky. It was designed to carry 75 passengers. In October of the same year Moscow plant № 30 was built the first production Il-18 for 89. In March 1958 completed factory and in August of the same year joint tests in NII VVS. In September, the Il-18A was exhibited at the world exhibition in Brussels, where he received a Gold medal. In the same month, the airliner has successfully completed the state testing.
Four-engine airliner Britannia started to be developed on the instructions issued in 1946, for long-haul flights to the outskirts of the British Empire. Originally it was going to equip with piston engines, but in 1949 they were replaced TVD “Proteus”. The first prototype flew on 16 August 1952 mass production of the Britannia was carried out between September 1954, However, forced landing in Uganda in operational trials in March 1956 delayed the introduction of the aircraft on regular routes. The first flight from London to Johannesburg, the plane made 1 Feb 1957
Four-engine passenger turboprop aircraft L-188 was created under the requirements of the airline “American airlines”. In June 1955 the project was chosen from among submitted various aircraft manufacturing firms in the USA. New car interested in other airlines. The prototype of the “Electra” took to the skies on 6 December 1957, the serial production at the plant of the company “Lockheed” in Baer Bank began in October, 1958 January 12, 1959 the aircraft, “Eastern air lines” made the first flight from new York to Miami.
