Answer KH-2-2015 Samolot myśliwsko-bombowy Su-7 BM

The Sukhoi Su-7 is a Soviet fighter-bomber with oblique wings, full metal structure with a classic tail. The drive was provided by a single Lulka AL-7F1 engine. The flight of the prototype took place on September 8, 1955. It entered the line in 1958. The first production version was the machine designated as Su-7, acting as a fighter plane. However, a very interesting tactical variant of the Su-7B quickly appeared. At the end of the years. 50, the Soviet command promoted the concept of "atomization" and "rocketization" of the battlefield. The main role of carrying atomic charges on the tactical battlefield was to be played by ground-to-ground missiles and barrel artillery, but for the elimination of particularly mobile cells (columns of troops) or requiring a precise strike (nuclear weapons of the enemy, secured command and communication stations), it was intended to be used as carrier of a high-speed supersonic plane. Due to the high speed, large payload, "strong" engine and the appropriate range, and equally importantly, the need to quickly put the machine into service (before the Su-7B, provisionally modified Mig-15 / -17 was used for this role), the choice fell on the Sukhoi design. In the mid-1960s, the plane was recommended for serial production of the Suchoja Su-7B, the first units left the production line in the second half of this year. Later, new versions were created, such as the Su-7BM, with additional rocket launch engines, the Su-7UB, i.e. a training version with a two-person cabin, or the Su-7BK or Su-7BKL versions. Technical data: length: 16.8m, wingspan: 8.77m, height: 4.8m, maximum speed: 1.6Ma, climb speed: 152m / s, practical ceiling: 15500m, maximum range: 1450km, armament: permanent- 2 NR-30 30mm cannons, suspended - up to 4000 kg of cargo on 4-6 under-wing pylons.
