Su-39 — rebirth Su-25

The Su-39 (Su-25TM, factory index 8TM T) is a deep modernization of the tip-proven predecessor — the Su-25. Work on the new aircraft began in January 1986. Then, by the decision of the MIC USSR Council of Ministers, work began to build versions of the Su-25T (anti-tank version armed with missiles "Whirlwind") capable of operating at any time of the day. On the new plane planned to install new avionics and use the extended range weapons. From the new attack aircraft required the effective application of tools in the area of finding purpose and reliable to overcome possible enemy air defenses, the ability of the flight at low altitude with the terrain following.

Own first flight preproduction attack T8TM-3 completed August 15, 1995. In the same year the car starts officially known as the Su-39. At the current time, built four aircraft of this modification, with all this, the Su-39 as in the past continues to pass a series of state tests. According to the views of analysts, recently the main task of aviation defending side will shock defeat armored units of the country an aggressor or, at least, delay the pace of their progress in a public area, in order to enable ground forces to regroup and organize the active response actions. Modern Russian attack plane The Su-39 can solve this puzzle within a radius of 900 km.

The design of the Su-39 as a whole was similar design training and combat aircraft Su-25UB. Only the Su-39 pilots took second place Myagenko extra fuel tank, and above it the compartment to accommodate additional avionics. Double barrel gun mount has been moved from the axis of symmetry of the aircraft to the right to 273 mm. and moved under the fuel tank, under the car seat vacated took additional avionics. The front landing gear as the aircraft was shifted — to the left of the axis of symmetry by 222 mm. The aft fuselage attack aircraft positioned next Myagenko extra fuel tank.

Since the Su-39 is the future development of "anti" version Sou-25T task to combat armored vehicles for it is the principal, but not dominant. The implication is that the brand new car will be able to perfectly hit ships in coastal areas, a front-line transport and enemy aircraft, air defense and infrastructure of the enemy. With all of this complex avionics and weapons attack aircraft underwent significant revision.

The upgraded machine was the latest radar "Spear-25" in a special container, the implement, which greatly expanded the ability of the aircraft. Since the Su-39 can carry a real dogfight with enemy aircraft, for that in his arsenal includes SD "air-air" P-73, P-27 and P-77, which own-range launch 20/40, 50/90 and 80/110 km, respectively. To fight the enemy naval groupings used anti-ship missiles Kh-31A, owning up to launch a range of 110 km. To fight the enemy radar used anti-radar missiles Kh-31P and Kh-25MPU. Arsenal against ground targets has been added precision missile "Whirlwind."

The Su-39 without the help of others can identify the target, select the priority and use the appropriate type of weapon. He has to choose from what, on 11 hardpoints (5 on each wing and one under the fuselage) can be positioned up to 16 anti-tank "Whirlwind" to 4 antiradar either anti-SD-class "air-surface", a wide range of SD "air-to-air." In addition, you can use up to 8 units starting with the 160th rockets, and various class incendiary bombs and tanks, up to 4 cannon mounted containers. Also in attack aircraft fuselage built-barrel 30mm automatic cannon GS-30.

The introduction of modern navigation equipment has made the Su-39 around the clock and all-weather, and allows you to do absolutely flying in the automatic mode. The new attack is designed to address 3 main objectives:
-destruction of tanks, armored personnel carriers, infantry fighting vehicles and self-propelled guns on the battlefield, on the march, and their places of congestion before entering into battle day or NIGHT MODE and in adverse weather conditions;
-destruction of naval targets of different classes: landing barges, speedboats, frigates and destroyers;
-destruction of Army aviation, languid and percussion military transport aircraft in the air and on the ground.

One of the main tools of the new attack aircraft were non-stop automatic sighting system "Squall" developing Krasnogorsk plant. Zvereva, as up to 16 anti-tank "Whirlwind." The Su-39 has a very good stability in flight, allowing in conjunction with the "Squall" at a distance of 10 km. provide a target accuracy of 60 cm Given the higher the possibility of destroying the target missile 1 "Whirlwind", the 1st ammunition Su-39 is sufficient for the defeat of 14 armored enemy targets. To compare the ordinary Su-25 can carry up to 160 rockets S-8, which can only hit one tank.

The main purpose of anti-tank "Whirlwind" — a direct hit from the liquidation of modern MBT with a width of up to 1 meter of armor. The possibility of defeat on the ground-moving German tank "Leopard 2" with one missile "Whirlwind", which vypushena attack aircraft Su-39 for target designation, acquired from the electro-optical sighting system "Squall" is 0,8-0.85. With all of this in the arsenal of attack aircraft, and there are far more languid UR, such as X-29T, X-29L and Kh-25ML.

It is especially necessary to emphasize the fact that using anti-tank "Whirlwind" the Su-39 can destroy enemy armored vehicles from outside the area acts of his air defense systems. With all of this small magnitude comparable to the cleared altitude rocket launch and a small distance to the target can use the "Whirlwind" in the criteria of limited visibility. For example, the meteorological conditions at 2 km. 200 m to the criteria of modern Europe, when the clouds quite often a lower edge at 200 meters, only the Su-39 can pretty well hit the mobile armored enemy targets.

Attack plane The Su-39 is able to produce takeoff and landing with a combat load on runways partially cooked with ground cover, including those located in the highlands at an altitude of 3000 meters above sea level with a runway length 1,200 m Power plant contains a stormtrooper Statement 2 of turbojet engines R-195 thrust of 4,500 kg each. Separately to emphasize their reduced infrared signature. With all of this craft are able to take on board the combat load of up to 4,000 kg.

According to the aspect of the price / performance of the Su-39 is superior French Mirage-2000-5, the South American F-16C, Swedish LJAS-39 at about 1.4-2.2 times. Attack aircraft can be used on diesel engines without resource constraints and does not require highly skilled maintenance. This machine is available in the development of military pilots at least some qualifications.

The persistence of the Su-39 significantly increased

Funds battle survivability of the Su-39, weighing 1115 kg. provide a machine virtually 100% protection of the pilot and the actual principal components and assemblies from damage by fire gunnery guns caliber 30 mm, also return and landing at the airport in case of defeat MANPADS machine type "Stinger". Managed to achieve this at the expense of diversity and protected the fuselage two-engine propulsion system and the ability to continue the flight on one working engine. With all of this pilot is protected by titanium unit, which is able to withstand a direct hit by a 30-mm shells, also has a bulletproof windshield and bronenadgolovnik.

Additionally responsible for the attack aircraft survivability complex military counteraction "Irtysh", which includes: active jamming station "Gardenia", the station detection, direction-finding and identification of the irradiating plane Radar, generator active IR interference "Bulk", chaff ejection system and tracers. Launcher HC-26 and IR jammer can hold a 192 invalid target PPR-26 (radar) or PPI-26 (heat), which are mounted in a single unit, located at the bottom of the keel plane.

To reduce the visibility of attack aircraft over the battlefield in the optical spectrum Sou-39 has a special coloring, and applied to the body radio-absorbing coating reduces the EPR irradiation aircraft radar. Protection of attack aircraft, when the pilot is unable to find a missile launch from the thermal head guidance is mounted at the bottom of the keel station opto-electronic interference "Bulk." Installed here cesium lamp 6 kW generates an amplitude-modulated interference missiles, away to the side. Not forgotten and more than a folk remedy — a program shooting infidels thermal purposes PPI-26.

Decrease the visibility of attack aircraft propulsion system contributes to besforsazhny TRD F-195 with a fixed nozzle and reduced to a couple of times the IR signature of the nozzle. This was achieved by profiling the flame tube and increased central body, which eliminates the line of sight of the turbine blades. Plane was also markedly reduced by reducing the temperature of the exhaust gases supplied by air.

The principal component of growth survivability Su-39 is the introduction of electronic warfare, which build the possibility of overcoming the enemy's air defense system. The basis of the information system of the complex EW "Irtysh" is an electronic intelligence station (SRTR), which is able to pelengovat all the fire control radar and detection. In preparation for a combat mission, you can program the search radar with setting their priority. Information irradiated ground attack enemy radar is displayed on a special indicator in the cockpit, with the source of radiation and its direction.

Owning information SRTR, the pilot of attack aircraft, depending on the tactical situation and the tasks can: strike on radar missiles, air defense system around the affected area, set the active radio station interference "Gardenia", or perform a soft shooting infidels purpose to evade SD with radar homing . Two compact container stations "Gardenia", mounted on the outer underwing hardpoints. These stations generate misleading, twinkling, steerable noise and interference on the underlying surface.
