The Su-25 and Su-39 single seat close support aircraft, known by the NATO reporting name Frogfoot, is manufactured by the Sukhoi Design Bureau Joint Stock Company, based in Moscow, and the Novosibirsk Aircraft Production Association, in Novosibirsk, Russia.

The Su-25 is designed to defeat small mobile and stationary ground targets and to engage low-speed air targets at the forward edge and in the nearest tactical and operational depth.

Variants of the Su-25 are operational with the Russian Air Force, the Russian Naval Aviation forces, Afghanistan, Angola, Azerbaijan, Belarus, Bulgaria, Czech Republic, Georgia, Iran, Iraq, Kazakhstan, North Korea, Peru, Slovak Republic, Turkmenistan and the Ukraine. The export variant of the aircraft carries the designation Su-25K.

A two seat variant Su-25UB, known by the NATO codename Frogfoot-B, is a weapons training aircraft manufactured at Ulan-Ude. The rear tandem seat is raised to give the instructor pilot good visibility.

The Su-25UTG is the two seater aircraft carrier variant fitted with an arrester hook under the tail. The Su-25UTG is deployed on the Russian Navy 50000-ton aircraft carrier Admiral Kuznetsov.

The wings have 10 pylons for carrying a range of air-to-air and air-to-ground weapon systems selected for the mission. The aircraft is equipped with an integrated navigation and aiming system including ASP-17 BTs-8 gun/bomb sight with an AKS-750s camera installed in the nose. The nose also houses a Klyon PS laser ranger and target designator, manufactured by the Urals Optical and Mechanical Plant (YOM3).

MISSILES

Air-to-ground missiles include the Kh-23 (known by the NATO codename Kerry and designation AS-7), the Kh-25ML (Karen AS-10) and the Kh-29L (Kedge AS-14)

The air-to-air missiles carried on the smaller outboard pylons are the R-3S (known by the NATO codename and designation Atoll AA-2D) and the R-60 (AA-8 Aphid).

ROCKETS AND BOMBS

The aircraft can be fitted with UB-32A pods for 57 mm S-5 rockets, B-8M1 pods for 80 mm S-8 rockets, S-24 240 mm guided rockets and S-25 330 mm guided rockets.

The Su-25 can be armed with 350 kg to 670 kg laser guided bombs, 500 kg incendiary devices and cluster bombs.

GUNS

The aircraft's twin barrel gun, the 30 mm AO-17A, is installed in the underside of he fuselage on the port side. The gun is armed with 250 rounds of ammunition and is capable of firing at a burst rate of 3,000 rounds per minute.

SPPU-22 gun pods can also be installed on the underwing pylons. The pods carry the GSh-23 23 mm twin barrel guns each with 260 rounds of ammunition.

ELECTRONIC WARFARE

The electronic warfare suite includes an SPO-15 Sirena-3 radar warning receiver and a Gardeniya radar jammer. The ASO-2V decoy dispenser can deploy chaff and flares for protection against radar and infrared guided missiles.

AVIONICS

The aircraft is equipped with an RSBN tactical air navigation system (TACAN), a type MRP-56P marker beacon receiving unit, an RV-1S radio altimeter and various air data and acceleration indicators.

The communications systems include an SRO-2 Identification Friend or Foe (IFF) transponder, an SO-69 air traffic control transponder, together with V and UHF transceivers and an air-to-ground radio.

COCKPIT

The aircraft has an all-welded 24 mm titanium alloy cockpit with transparent windscreen armor block to protect the pilot and is equipped with a single K-36L Zvezda ejection seat.

ENGINES

The Russian airforce Su-25 aircraft is powered by two Soyuz/Gavrilov R-195s turbojet engines rated at 44.18 kN. Cooling air is introduced at the end of the tailcone to reduce the temperature of the exhaust gasses and minimize the infrared signature of the aircraft.

The aircraft is equipped with self sealing foam filled fuel tanks with a total capacity of 3,600 liters of fuel. The range of the aircraft can be extended by the provision of four external fuel tanks, type PTB-1500, which are carried on the underwing pylons.

CONSTRUCTION

The aircraft is all metal semi-monocoque design with a slab-sided fuselage and shoulder mounted wings. A notable design feature of this aircraft is the enhanced survivability. The cockpit is armor protected and pushrods are used in preference to cables for the flying control surfaces. The load bearing members are strengthened. The engines are widely separated and a 5 mm thick firewall is installed between them. The explosive resistant fuel tanks are filled with reticulated foam.
