Single-seat variable geometry ground attack fighter, reconnaissance aircraft and two-seat combat trainer.

PROGRAMME:

Prototype S-22I or Su-7IG (Izmenyaemaya Geometriya; variable geometry) was minimal conversion of fixed-wing Su-7 (NATO `Fitter-A'); only 4.2 m (13 ft 9 in) of each wing pivoted, outboard of large fence and deepened inboard glove panel; first flew 2 August 1966; shown at Aviation Day display July 1967; given NATO reporting name `Fitter-B'; two squadrons of Su-17 `improved Fitter-Bs' in Soviet air forces 1972; AL-21F-3 engine then replaced AL-7 in major Soviet air force production versions, beginning with `Fitter-C'. Production ended 1991.

VARIANTS:

Su-17M (S-32M, `Fitter-C'): Single-seat attack aircraft; AL-21F-3 engine; eight stores pylons; ad***ional wing fence on each glove panel; curved dorsal fin; operational with CIS air forces and Naval Aviation since 1971 in relatively small numbers. Detailed description applies to basic Su-17, except where indicated otherwise.

Su-17R: Reconnaissance version of Su-17M.

Su-17M2/M2D (S-32M2, `Fitter-D'): Generally as Su-17M, but forward fuselage lengthened by 0.38 m (15 in) and drooped 3° to improve pilot's view while keeping intake face vertical; added undernose Doppler navigation radar pod; Klen laser rangefinder in intake centrebody.

DESCRIPTION:

Description applies to basic Su-17, except where indicated.

DESIGN FEATURES:

Modest amount of variable geometry added to original fixed-wing Su-7 permitted doubled external load from strips little more than half as long, and 30 per cent greater combat radius; progressive refinements led to very effective final versions. Conventional mid-wing all-swept monoplane, except for variable geometry outer wings with manually selected positions of 28°, 45°, 63°; wide span fixed centre-section glove panels; basically circular fuselage with dorsal spine; ram intake with variable shock-cone centrebody; pitot on port side of nose, transducer to provide pitch and yaw data for fire control computer starboard; anti-flutter bodies near tailplane tips.

FLYING CONTROLS:

Slotted ailerons operable at all times; slotted trailing-edge flap on each variable geometry wing panel operable only when wings spread; area-increasing flap on each centre-section glove panel; full-span leading-edge slats on variable geometry wing panels; top and bottom door type airbrakes each side of rear fuselage, forward of tailplane; all-moving horizontal tail surfaces; conventional rudder; no tabs.

STRUCTURE:

All-metal; semi-monocoque fuselage; large main wing fence on each side, at junction of fixed and movable panels, square-cut at front, with attachment for external store; shorter fence above glove panel each side.

LANDING GEAR:

Retractable tricycle type, with single wheel on each unit. Nosewheel retracts forward, requiring blistered door to enclose it. Main units retract inward into centre-section. Container for single cruciform brake-chute between base of rudder and tailpipe.

POWER PLANT:

One Saturn/Lyulka AL-21F-3 turbojet, rated at 76.5 kN (17,200 lb st) dry and 110 kN (24,700 lb st) with afterburning. Fuel capacity increased to 4,550 litres (1,202 US gallons; 1,000 Imp gallons) by added tankage in dorsal spine fairing. Provision for carrying up to four 800 litre (211 US gallon; 176 Imp gallon) drop tanks on outboard wing pylons and under fuselage. When underfuselage tanks are carried only the two inboard wing pylons may be used for ordnance, to a total weight of 1,000 kg (2,204 lb). Two solid propellant rocket units can be attached to rear fuselage to shorten T-O run.

ACCOMMODATION:

Pilot only, on ejection seat, under rearward hinged transparent canopy. Rearview mirror above canopy.

AVIONICS:

SRD-5M (NATO `High Fix') I-band ranging radar in intake centrebody; ASP-5ND fire control system; HUD standard; Sirena-3 radar warning system providing 360° coverage, with antennae in slim cylindrical housing above brake-chute container and in each centre-section leading-edge, between fences; SRO-2M IFF; SOD-57M ATC/SIF, with transponder housing beneath brake-chute container; SP-50 ILS, RSB-70 HF and RSIU-5/R-831 UHF/VHF.

ARMAMENT:

Two 30 mm NR-30 guns, each with 80 rounds, in wingroot leading-edges. Total of nine weapon pylons (one on centreline, two tandem pairs under fuselage, one under each centre-section leading-edge, one under each main wing fence) for more than 3,175 kg (7,000 lb) of bombs, including nuclear weapons, rocket pods, 23 mm gun pods and guided missiles such as the air-to-surface AS-7 (NATO `Kerry'), AS-9 (`Kyle') and AS-10 (`Karen').

The "Conmilit" of the August issue sponsored by China's Information Center of National Defence Science and Technology makes an overall evaluation of the current arms situations of India. The main points include:
It is believed that India will further develop its missile-carrying nuclear submarines and SLBMs while stressing the on-going development of its land-based nuclear attack capability. It is estimated that by early next century, India will have preliminarily established its nuclear attack capability with bombers, land-based ballistic missiles, and submarine-launched missiles as the major elements. The Indian air force will

1. continue to develop the LCAs. It is initially planned to produce 100 such planes to replace the MiG-21. It is expected that these LCAs will be deployed for combat use from the year 2002 to the year 2010;

2. develop the MCAs that has a stealth function. They will be put to use from the year 2008 to the year 2010 in place of Jaguar SI and Mirage 2000 fighter planes;

3. develop the new cruise missile on the basis of the PTA unmanned planes. Utilizing inertia and the technology of GPS guiding, this cruise missile has its head weighing about 450 kilograms and can be launched as far as 600 gl kilometers. It is predicted that its development will be completed in the year 2000 or so;

4. successfully develop the new multi-functional high-class LHC. At present, the LHCs are being produced in batches. They will be used as the major equipment for the India's helicopter troops in the future;

5. plan to purchase some more new Mirage 2000 5 fighter planes to equip a squadron. Under the contract on the purchase of 40 SU30MKI multi-functional fighter planes from Russia, the first eight planes were handed over to the Indian air force in March of 1997 and the rest will have been delivered to India in three batches by the year 2000;

6. purchase the licence for the production of the Russian Su30-MKI fighter planes. The contract involves one billion US dollars. It is planned that about 100 Su30MKI will have been produced by the year 2010;

7. improve the strategic and tactical air transport capabilities. It is believed that the Indian air force is planning to increase its number of airfreighters from current 192 to 300 by the end of this century. In ad***ion, India is considering purchasing more Russia-made Il76 heavy-duty airfreighters;

8. plan to purchase from Russia an Admiral Gorshkov aircraft carrier with the contract value of one billion US dollars;

9. build on its own a light-duty aircraft carrier with a displacement of 17,000 tons. Consuming a manufacturing cost of 330 million US dollars and having a loading capacity of 12 to 15 fighter planes, this aircraft carrier will be launched in the year 2002 as planned;

10. continue to build the large Delhi class destroyer with a displacement of 6000 tons and to import the Kilo submarines, the Tu142 marine reconnaissance planes, and Il-38 anti-submarine planes.
