Basic operational task

Single-seat all-weather counter-air fighter and ground attack aircraft.

Program

The development of the Su-27M was authorised on 29 December 1993 by the Council of Ministers. An experimental version of the Su-27 with foreplanes (T10-24) flew May 1985. The improved FBW system and refuelling probe were tested by airframe T10U-2. Five prototypes were produced by conversion of production Su-27s, which retained the single nosewheel and standard tailfins: T10M-1 “701”, then lacking a radar and a weapon control system, flew 28 June 1988. T10M-2 was flown 18 January 1989. Further prototypes are T10M-5, T10M-6 “706” and T10M-7 “707”. These were used mainly at the Akhtubinsk test centre, flown by service pilots.

Production

Production at KnAAPO, Komsomolsk, beginning with static test airframe T10M-4. The types (Komsomolsk built) first flight was 1 April 1992 (by airframe T10M-3 “703”), the latter was exhibited at the 1992 Farnborough Air Show. Of a further six ordered (T10M-8 to 13, “708” to “713”) “711” and “712” were transferred to the Su-37 program and “713” was cancelled. Large-scale series production was originally planned 1996-2005 as an interim fighter pending the availability of the Mikoyan MFI. Three aircraft (Blue 86, 87 and 88), described by KnAAPO sources as ”production Su-35s”, but probably ex-“707”, “708” and “709”, were delivered to Akhtubinsk from Komsomolsk in 1996 or 1997. It is not known whether they were fitted with thrust-vectoring engines (which could make them more properly Su-37s ).

Versions

Su-35

The baseline single-seater. It has new digital pilot control and digital engine control systems, replacing the analog computers in the original Su-27. The radar, with a range of 400 km, can follow the position of 15 targets and fire at 6 of them at the same time. An improved Zhuk radar features a mobile (+/- 130 degree) antenna which can follow position of 24 targets with ability to fire to 8 of them.

Su-35UB

Two-seat derivative of the Su-35 with the same FCS, canard foreplanes, tall square-topped tailfins, 12-pylon wing, a Zhuk main AI radar and a N012 rearward-facing radar, as well as a tailcone-mounted radar. Developed as a demonstrator and trainer for the Su-35, the construction of the prototype (Blue 801) may have been prompted by the needs of Sukhoi's campaign to sell the Su-35 to South Korea. The aircraft first flew on 7 August 2000 and was reported to be undergoing trials at Akhtubinsk in October 2000. It is implied that this aircraft has 245 kN (55,115 lb st) AL-31FP (AL-31F) thrust-vectoring engines (which would make it more properly an Su-37UB ). The Su35UB has a 38,800 kg (83,775 lb) MTOW and a 8,000 kg (17,637 lb) combat load. The maximum speed is 2,020 km/h (1,255 mph), while it has a 3,000 km (1,864 mile) unrefuelled range. The wing span is 14.70 m (48 ft 2 in), length overall 21.94 m (71 ft 11 in) and it’s height overall is 6.355 m (20 ft 10 in).

Operators

The aircraft was once scheduled for entry into Russian Air Force service as Su-27M from 1995 onwards, for effective operation until 2015-2020 The program was in suspension and may have been superseded by the Su-37.

Technical information

Design features

This aircraft is an advanced multirole development of the Su-27 to counter the latest versions of the USAF F-15 Eagle and F-16 Fighting Falcon , with better dogfighting characteristics, higher Angle of Attack limits, lighter weight and new BVR armament. It was proposed to include the 400 km (248 mile) range AAM-L. It was also planned to have greater autonomy from GCI control. The airframe, power plant, avionics and armament have all been upgraded from the standard Su-27. Axisymmetric thrust-vectoring nozzles were under development for use on production aircraft (see Su-37 ).

Power Plant

Production Su-27M/Sukhoi Su-35s were planned to use two NPO Saturn AL-35F (aka AL-37FM turbofan engines, each 125.5 kN (28,218 lb st) with afterburning, while the prototypes retained the standard AL-31F.

Crew

Pilot only, who is seated on a Zvezda K-36MD zero/zero ejection seat, this now angled back 30 degrees.

Armament

One 30 mm GSh-30 gun in the starboard wingroot extension, with 150 rounds. Mountings for up to 14 stores pylons, including R-27 (AA-10 “Alamo-A/B/C/D”), R-40 (AA-6 “Acrid”), R-60 (AA-8 “Aphid”), R-73E (AA-11 “Archer”) and RVV-AE (R-77 AA-12 “Adder”) AAMs, Kh-25ML (AS-10 “Karen”), Kh-25MP (AS-12 “Kegler”), Kh-29T (AS-14 “Kedge”), Kh-31P (AS-17 “Krypton”) and Kh-59 (AS-18 “Kazoo”) ASMs, S-25LD laser-guided rockets, S-25IRS IR-guided rockets, GBU-500L and GBU-1500L laser-guided bombs, GBU-500T and GBU-1500T TV-guided bombs, KMGU cluster weapons, KAB-500 bombs and rocket packs. The maximum weapons load is 8,200 kg (18,077 lb).
