Operators: Russia*

History: Development of advanced Su-27s variants began in the mid 1980s.

A development Su-27 fitted with canards flew for the first time in May 1985, while the first prototype for what would become the Su-35, the T-10S-70, first flew on June 28 1988. For a time the improved Su-27 was designated Su-27M, it has since been redesignated Su-35.

Changes over the basic Su-27 are numerous. Canard foreplanes were added while power is from two upgraded Saturn AL-35F (or AL-31 MF) turbofans. Flight control is provided by a digital fly-by-wire system with quadruplex redundancy (the Su-27's fly-by-wire system is analog). The reprofiled nose houses a multimode Phazotron N011 Zhuk 27 radar (with a larger diameter, flat plate antenna) which has a search range of 100km (55nm), can track 24 targets simultaneously and has terrain following/avoidance. The tailcone houses a rearwards facing Ryazan radar. A new IRST set has been repositioned on the nose. The EFIS cockpit features three color CRTs and a HUD. Other features are a retractable in-flight refuelling probe, taller squared off fins each containing an auxiliary fuel tank and twin nosewheels. Some have been noted with large ECM wingtip pods.

The Su-37 first flew in 1996 and is a further improvement of the Su-35 with two dimensional thrust vectoring nozzles operated through the fly-by-wire flight control system. Other Su-37 features include a Zhuk-PH phased array radar and an improved cockpit with sidestick controller and four Sextant LCD multifunction displays.

The Russian air force had hoped to introduce the Su-35 into service in the late 1990s, although these plans may have been overtaken by the availability of the Su-37."

SUKHOI Su-35 (Su-27M)


Type

Multirole fighter.

Programme

Development of Su-27M authorised on 29 December 1993 by Council of Ministers. Experimental version of Su-27 with foreplanes (T10-24) flew May 1985; improved FBW system and refuelling probe tested by T10U-2. Five prototypes produced by conversion of production Su-27s, retaining single nosewheel and standard tailfins: T10M-1 `701' (ex-1602), then lacking radar and weapon control system (successively T10S-70, T10M, Su-27M, Su-35) flew 28 June 1988; T10M-2 flown 18 January 1989; T10M-5, T10M-6 `706' and T10M-7 `707'; used mainly by NII VVS at Akhtubinsk, flown by service pilots.
Production at KnAAPO, Komsomolsk, beginning with static test airframe T10M-4; first flight (T10M-3 `703') 1 April 1992; latter exhibited at 1992 Farnborough Air Show. Of further six ordered (T10M-8 to 13; `708' to `713') `711' and `712' transferred to Su-37 programme and `713' cancelled. Large-scale series production originally planned 1996-2005 as interim fighter pending availability of 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).

Current Versions

Sukhoi Su-35: Baseline single-seater; as described.
Sukhoi Su-35UB: Two-seat derivative of the Su-35 with same FCS, canard foreplanes, tall square-topped tailfins, 12-pylon wing, Zhuk main AI radar and N012 rearward-facing , 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).
Su35UB has 38,800 kg (83,775 lb) MTOW; 8,000 kg (17,637 lb) combat load; 1,090 kt (2,020 km/h; 1,255 mph) max speed; 1,619 n mile (3,000 km; 1,864 mile) unrefuelled range; wing span 14.70 m (48 ft 2Ѕ in); length overall 21.94 m (71 ft 11Ѕ in); and height overall 6.355 m (20 ft 10ј in).

Customers

Once scheduled for entry into Russian Air Forces service as Su-27M from 1995 onwards, for effective operation until 2015-2020; programme in suspension and may be superseded by Su-37.

Design Features

Advanced multirole development of Su-27 to counter latest versions of USAF F-15 Eagle and F-16 Fighting Falcon, with better dogfighting characteristics, higher AoA limits, lighter weight and new BVR armament; proposed to include 216 n mile (400 km; 248 mile) range AAM-L (one AAM-L contender was Novator KS- 172). Also planned to have greater autonomy from GCI control. Airframe, power plant, avionics and armament all upgraded; quadruplex digital fly-by-wire controls under development by Avionika, though prototypes retain analogue system; longitudinal static instability; `tandem triplane' layout, with foreplanes; double-slotted flaperons; taller, square-tip twin tailfins with integral fuel tanks; reprofiled front fuselage for larger-diameter radar antenna; enlarged tailcone for rearward-facing radar; twin-wheel nose landing gear; axisymmetric thrust-vectoring nozzles under development for use on production aircraft (see Su-37).

Structure

Higher proportion of carbon fibre and aluminium-lithium alloy in fuselage; composites used for components such as leading-edge flaps, nosewheel door and radomes.

Power Plant

Production Su-27M planned to use two Saturn/Lyulka AL-35F (AL-37FM) turbofans; each 125.5 kN (28,218 lb st) with afterburning; prototypes retain standard AL-31F. Increased internal tankage (approximately 1,500 kg; 3,307 lb) through use of welded aluminium-lithium tanks and new tanks in tailfins. Retractable flight refuelling probe on port side of nose.

Accommodation

Pilot only, on Zvezda K-36MD zero/zero ejection seat, this now angled back 30є.

Avionics

Radar: Originally planned to incorporate NIIP N011 Zhuk-27 multimode low-altitude terrain-following/avoidance radar, search range up to 54 n miles (100 km; 62 miles) against advancing target, 30 n miles (55 km; 34 miles) against retreating target; able to track 15 targets and engage four to six simultaneously. Phazotron Zhuk-Ph phased-array radar under development as alternatives or for retrofit; search range for fighter-size targets 75 n miles (140 km; 87 miles) with simultaneous tracking of 24 air targets and ripple-fire engagement of six to eight; N012 rearward-facing radar, range approximately 2 n miles (4 km; 2.5 miles), may enable firing of rearward-facing IR homing AAMs.
Flight: Fully automatic flight modes and armament control against ground, maritime and air targets, including automatic low-altitude flight and automatic target designation. RPKB nav system includes laser-gyro INS and Glonass GPS.
Instrumentation: EFIS, with three colour CRTs; HUD.

ur not goning to get it, coz u got a similar plane in the SU-30MKI.

Also maintaining Flankers is costly, very costly, so that 126, won't be flankers.

Kidding me? The MKI's are one of the most efficient planes in the world today. But the IAF won't opt for the MI's for the M-MRCA role because the IAF uses them as an Air Superiority fighter and not as a Multi Role Fighter. Cost is hardly an issue with that regard.

Srirangan,
my Q is why shouldn't su-35/37 which is developed as multi-role fighter be considered ? .What i was trying to say if su-30 mki comes at 37.5 millionj $ , surely 35/37 could come at similar price which is much much lower than mirage 2000-5 at 55 million $ est.

Multiple reasons. IAF always prefers a diversified air force. IAF already operates the Mirage 2000's and MiG 29's. Most importantly Sukhoi hasn't placed a bid ;-)

Technically the Su-30 can be a multi role fighter too. The IAF has this platform, just not for the MRCA role.

The ultimate Q is which AC would be potent Mirage 2000-5 or (untested) Su-35/37 ?
If IAf chooses 35/37 than Training etc cost would be low, better in long term.

SU-30 is a twin engine fighter.....Mirage 2000 is a single engine fighter....

half the engine maintaince....

Flankers are expensive and hard to maintain, it's well known fact.

google for it man.

.

U r wrong. Flankers are cheaper simply b'coz its a 2 engine heavy AC, at around 35-40 million $. While mirage 2000-5 a single engine AC & medium class, at around 55-60 million $ .

Maintainance cost is different thing altogether .

i was talking about maintance all along....

A Cessna or a Fokker will have even less maintenance, so we shud opt for them as well?? IAF buys aircraft based on their force projection.

The moot Question is which is most potent platform , Su-35/37 or single engine murage 2000-5 ?

Originally Posted by indianguy4u

NO.. the Question is what platform suits us the best.
1. The su 35/37 dsnt have any dignificant advantage over MKI that can drive us to buy the new plane itself. Its better to make MKI's in india at 30 mn a peice(which shud go furhter down if we make more) than going for a su37/35 from russia at 35/37 mn a peice.
2. the 37.5 mn a peice is the cost for the MKI/37 which dsnt include the missiles and bombs, while th 55 mn a peice cost is for french manufacturing line produce bundled up with spares misiles bombs etc.The cost of missiles etc whoud be takjen out of the price tag before comparison. u remove the missiles and spares the cost shud be nearly half of figure for india.
3. cost of the same products produced in india (MKi and Mirage etc) will be the real price comparison. as most will be produiced in inida.
3. M2K is well known for having a pretty good uptime and maintenance record while MKI 37 etc arent proved ayt all in their maintenance and the russian record for the machine mean life before serive is pretty bad.
4. We cannot produce MKI type of machines faster They are complex machines. but making M2K will be much easier . Maintenace infra is already there for M2k.
5. what will be the doctrine role for a MRCA we need. this the main question. do we really need a machine gun for something that can be done by a pistol.U should compare thje land attack capability of M2k with that of MKI etc.
6. Uptime cost M2k weights less than even half of MKI.Delta structure makes it pretty fuel efficent too. the fuel cost per hour of flight for M2k is much much less than that for MKI. Add to it the fact that we need to train lesser number of pilots. transition to LCA from M2k will be much much easier.
7. we arent getting any new weapons with buying su37 but with M2k opens the doors for newer missiles bombs from EU, newer avionics. etc etc.
8. MKI etc cannot be flown from the standard feilds used by mig21 . they need much longer airstrip calling for a lot of infra upgrades.

almost evthing is against the SUs
the cost
uptime
maintenance records
production not possible in india. unlike that for M2k.

We shud realise that we dont need to send 4 mkis for a mission carrying land attack bombs primarily even at places where air superiority isnt that much needed . if a 1 mki with a few M2ks can do the job. as m2k are an excellent land attack platform.
