Suchoi Su-25

Su-25 of the Russian Air Force

the Suchoi Su-25 Frogfoot is a Soviet ground combat aircraft. It represents the Soviet counterpart to the Fairchild republic A-10 and fulfills similar tasks: the goal-exact destruction of ground targets, at day and night under all weather conditions. In particular the Su-25 (usually in the close group with ground troops) against armored vehicles, convoys, bridges, roads, starting and runways, railway lines as well as not or weakly loaded hoppers command and fire conditions as well as against helicopters begun.

history

the development of the Su-25 began in the year 1968. At that time developed with Suchoi in a team under the direction of Zhurii V. Ivanshezkin first drafts of one internally T-8 machine mentioned. First the official interest was reserved, this changed only in the years 1972/1973. At the 22.Februar 1975 Vladimir S.Iljuschin with first, still with two RD-9 - engines equipped, prototypes T-8-1 started in Schukowski to the first flight. Those far modified T-8-2 flew for the first time at the 26.Dezember 1975 with V.P.Valsilyev. Both prototypes were reequipped later on R-13-300. For the first Serienmaschinen one decided however for the again-developed R-95Sh - engine. The Su-25 stood in competition to Ilyushin the Il-102, Suchoi was however more successful and received orders for series of the V-VS. After its identification by NATO in the year 1977 the Su-25 received first the provisional designation Ramenskoye RAM j. It received the NATO code name “ Frogfoot” only in the year 1981.

In the comparison to the American A-10 the Su-25 is somewhat smaller dimensioned, ordered however by its two engines, which are attached in lateral cars at the trunk (in protecting housings from stainless steel), over a larger efficiency. As is the case for the A-10, then the pilot cab and the most important parts of offensive electronics are protected by a welded 12-24 mm strong titanium tub also with Su-25. The Pilotenkanzel is provided with a windshield from bullet-proof glass. The ground combat aircraft is equipped with a durable chassis for operations on combat air bases and needs only an extremely short runway of approximately 1200 m. Under the wings four housings can be carried, be contained the entire equipment for autonomous employments on these combat air bases, where there is only fuel (it can be used even gasoline or Diesel) and ammunition. The Su-25 has self sealing tanks in trunk and wing with a max. Capacity of 3.660 l fuel. Many systems of the control and regulation are several times implemented or by special devices from steel additionally protected for the increase of the probability of survival. The internal armament consists of a double-barreled cannon at the left nose lower surface. The ten supporting device (five under each wing, of it for each 1x for Luft-Luft-Raketen) knows a considerable load (max. 4400 kg) at freely falling weapons, at firing containers UB-16 and B8M1 for unguided rockets S-5 and/or. S-8, at guided missiles (Ch-23, Ch-25ML, Ch-29L) and at cannon containers SPPU-22 (basic load: 260 shot) with a vertically mobile cannon Gscha-23L take up. This cannon can be swivelled up to 40° downward. The cultivation of these cannon containers can take place also against the flight direction. Thus it is to be shot practically possible “to the rear”, for example if the ground target were already flown over and during the takeoff to be still fought is. The cultivation of infrared-guided rockets R-3S and R-60M for self-defense takes place at the outermost points of suspension, and at the other supporting device (mostly at the internal ever a fuel additive container) the cultivation of maximally four is per 800 litres and/or. ever 1,150 litres seizing fuel additive containers possible. The Su-25 is to be used able atomic tactical released weapons.

The Suchoi Su-25T is a Soviet military aircraft.

It is one from the Suchoi Su-25 developed increased combat effectiveness, also for the tank fight developed, single-seat all-weather version, in the rear cockpit is inserted avionics as well as a Treibstofftank. The first flight of the prototype T-8M was to 17. August 1984.

employment

in the year 1982 was placed the airplane into the service of the Soviet armed forces. It was used into Afghanistan first in a test unit, later in addition, into regular units. According to Soviet data only 22 total losses were to be registered during the employment of nine years in Afghanistan. With the decay to the former Soviet Union Su-25 arrived into the armed forces of the Russian federation, in addition, other succession states.

To the further countries in those the Su-25 to be used to belong: Ethiopia, Afghanistan, Angola, Armenia, Azerbaijan, Bulgaria, Eritrea, the Gambia, Georgien, Iraq, Iran, democratic Republic of the Congo, North Korea, Peru, Slowakei, Syria, Tschechien, Turkmenistan, Ukraine, Hungary, Usbekistan and white Russia.

The GDR was interested to the Su-25 as replacement in the MiG-23BN. There for the old MiG-23BN however no customers were found did not come off the business not.

production

the single-seat versions in low-read (today again Georgien) built, the two-seat versions in Ulan Ude. Developed over 1.300 Su-25 of different versions.
