Fighter Sukhoi Su-7
This aircraft is the first in the Soviet Union overcame the level of speed "two sounds." Its acceleration and altitude characteristics were the best in the world. Su-7 became an epoch in the history of domestic aviation.
In the early 50-s Air Force major world powers were armed jet fighters 1-generation. These machines had subsonic speeds of flight and machine-gun armament. The most popular among them were the Soviet MiG-15 and American F-86 Sabre.
In 1953, the Design Bureau. P. Sukhoi fighters engaged in the development of the second generation. This takes into account the experience of the Korean War, where MiGs and "Sabre" is not just converge in air battles. New cars were required to have a supersonic speed, Missiles and radar avionics. Dry immediately offered the government commission 4 option supersonic interceptor and fighter front triangle and swept wings. The new machines were to develop an incredibly high speed at the time 1800 km / h and climb to a height of 19 000 m.
During the meeting of scientific and technical council of the Sukhoi said: "This is a technical fantasy - a plane with such indicators is now impossible to build." It is worth recalling that in 1953, the Soviet Union did not have serial supersonic aircraft. The government has approved two projects, but defined very strict terms of transfer of aircraft to the test - of 1955 May
The reason was simple - the Cold War. The United States has conducted flight tests of the fighter so-called hundredth series: F-100, F-101, F-102 and F-104. These machines have been designed as the most rapid and the most high-rise in the world. The Soviet Union could not keep up with the air forces of a potential enemy. Therefore, the engineering team P. Sukhoi had to work with the utmost composure, and maximum efficiency. Work on both projects directly supervised Eugene Felsker.
In developing the second generation of fighters engineering team had to deal with many technical problems. It is evident design and organizational skills P. Sukhoi. Pavel Osipovich always provides its employees with greater autonomy, has sought to develop their creativity.
In 1954 the project was ready to front-line fighter-1 with swept wings. This aircraft was far ahead of its time. He had a perfect aerodynamic shape: strongly lean back wings strelopodobnoe plumage, a long cigar-shaped fuselage. With On-1 was installed powerful turbojet engine design cradles the Arkhip.
With 7.09.1955-1 made its first flight. Dry invited to experience the car of Colonel Andrei Kochetkov - one of the best Soviet pilots. It Kochetkov in August 45-th first raised in the air captured Messerschmitt Me.262.
Now he had to master a much more difficult fighter. At the same time the pilot had to decide not only technical, but also psychological problems: speed far beyond the sound barrier, a huge altitude - all of this had to overcome first. During the test-1 fighter managed to reach a given height - 19 000 m. The maximum speed reached 2170 km / h. For the first time in the history of the Soviet stepped winged machine for "two sounds." It was an adequate response to the American challenge.
11.06.1956 government decree plane launched into serial production under the designation Su-7. After a 2 weeks Sukhoi fighter aircraft, along with other innovations of domestic aviation was first put on display to the general public.
High-altitude, speed and acceleration characteristics of the machine surpassed the achievements of jet aircraft, not only in the Soviet Union, but also worldwide. The car was good handling and stability in flight, easy to perform aerobatics.
Armament and avionics of Su-7 quite consistent with military requirements. Modern rangefinder allows the pilot to attack targets in all visibility conditions, day and night. It seemed that the plane a bright future, but his fate changed dramatically in the 1958 year, just at the beginning of serial production. By the time the plant in Komsomolsk-on-Amur was released 132 machine.
In the middle of 50-ies in the Soviet Air Force attack aircraft eliminated. However, the task of supporting ground troops still remained on the shoulders of the Air Force. Frontline Aviation urgently required a specialized attack aircraft.
Replacement of obsolete and steel-10 MiG jet fighters and MiG-15-17. But everyone understood that this is only a temporary solution. MiGs, originally designed as a pure fighter, were not designed to carry out bombing and assault tasks. The eyes of the military leadership turned to Pavel Sukhoi, which at that time had already become chief designer. He was appointed during the year to create a specialized aircraft, fighter-bomber capable of carrying nuclear weapons and attack ground targets.
Having such a difficult task, Dry took the only right decision: with a clean slate new aircraft did not begin to do, and to finalize the new tasks Su-7. Of great importance in this case and had a productive factor. The industry has managed to master the production of this model, and serial production of the new aircraft would not have been any difficulties. In April, the 1959 test pilot E. Solovyov made its first flight on the prototype of the new machine. From the base model aircraft it features more fuel capacity, including mounted tanks, new avionics and weapons.
The modified "seven" could at high speed to overcome the enemy's air defense zone, to forward to the goal of a nuclear charge with the on-board weapons effectively hit the ground objects, and if necessary to engage the enemy fighters-interceptors.
In 1961, the aircraft brought into service under the symbol Su-7B. Flight characteristics of the new fighter-bombers were as high as that of the base model. Pilots combat units quickly fell in love with the car, which allows you to perform complex aerobatics in a wide range of speeds.
RATED Sioux 7B and aircraft that are engaged in its airfield services. Access to the units and apparatus of the aircraft has become easier. To do this, designers have made some additional hatches.
Fighter-bomber Su-7B became the main striking complex of Soviet tactical aviation for two decades. In addition, he was the ancestor of a large family of aircraft Sukhoi.
In 1957 was in KB P. О. Dry drafted two-seater fighter-interceptor P-1. The aircraft had to have high performance characteristics and powerful armament. Thus, the speed of the flight was to be 2050 km / h, the ceiling - 19 500 m. The aircraft was armed with unguided rockets 50. P-1 passed flight tests, but not commercially produced. Front-line fighter and KB P. О. Sukhoi Su-7 was launched into production in 1959 city This aircraft and its modifications have a high combat characteristics, they were among the best aircraft in its class. It is no coincidence that the Su-7 was the Air Force of the country for almost a quarter century.
As the power plant on the plane was used a turbojet engine designed by M. Cradles AL-7F-1. He developed a thrust without afterburner 68,6 kN, with afterburner running - 98,1 kN. The aircraft was armed with two guns, HP-3 30 mm caliber, in addition, could carry missiles.

In 1960 on the basis of the Su-7 was created Strike Fighter C-22, soon received another designation Su-7B. In 1960, he was adopted and became mass-produced at the plant № 126 (Komsomolsk-on-Amur).
Fighter could strike at remote bases opponent to hit the moving enemy targets on land, in the air, on the water surface and perform the actual fighter. The aircraft has been in service with the Egyptian air force and took part in the fighting in the war and Israel.
