R-33 on Su-27?

Skywall23 · March 9, 2005

hmm... I was checking a website about the russian aircraft and found an interesting matter. But I doubt that the Su-27 can support this missile since if such was the case, we would already be able to use it.

One 30 mm GSh-301 gun in starboard wingroot extension, with 150 rds. Up to 10 air-to-air missiles in air combat role, on tandem pylons under fuselage between engine ducts, beneath each duct, under each centre-wing and outer-wing, and at each wingtip. Typically, two short-burn semi-active radar homing R-27R (NATO AA-10A 'Alamo-A') in tandem under fuselage; two short-burn infrared homing R-27T (AA-10B 'Alamo-B') missiles on centre-wing pylons; and long-burn semi-active radar homing R-27ER (AA-10C 'Alamo-C') or infrared R-27ET (AA-10D 'Alamo-D') beneath each engine duct. The four outer pylons carry either R-73A (AA-11 'Archer') or R-60 (AA-8 'Aphid') close-range infrared missiles. R-33 (AA-9 'Amos') missiles optional in place of AA-10s.Five-round packs of 130 mm rockets, or larger rocket pods, under wings in ground attack role.

Anyone knew about this ???

On 26 November 1995, the first of two Su-27s was delivered to the USA inside an An-124 for an unknown purpose

Maybe I´m the only one surprised by this statement, I thought that the west hadn´t looked at the Su-27 more than in photographs or airshows. Or at least, nothing they would publically admit.

Su-27SK

The Su-27SK weapons deployed on 10 hard-points, include R-27 air-to-air missiles of all modifications and R-73E missiles. The unguided weapons are S-8, S-13 and S-25 unguided rockets and aerial bombs of up to 500 kg calibre. The aircraft has a built-in GSh-301 gun with the ammunition allowance of 150 rounds.

It doesnt mention the capability of the Su-27 to use the R-33. Hmmm, the russian hardware it quite misterous. But anyway the Su-27SK is an export version.

More misterious is the fact that ED decided to implement A2G capability on the standard Su-27 but I dont have any source that indicates that the Flanker-B can carry such weaponry.

I have a list of ALL versions of the Flanker:

Su-27 (`Flanker-B'): Single-seat land-based production version for air defence force (PVO); full-span leading-edge flaps, trailing-edge flaperons, 5 per cent increase in wing area, straight leading-edges, new aerofoil, square wingtips, carrying anti-flutter weights which doubled as AAM launchers; wider-spaced, uncanted tailfins outboard of engine housings; flatter canopy of reduced cross-section; extended tailcone instead of flat `beaver-tail'; forward-retracting nosewheel; first flown (T10-7) 20 April 1981. Standard radar tracks 10 targets simultaneously, engages only one. There was early, but probably erroneous, speculation that PVO aircraft were designated Su-27P, with Su-27S designation applied to Frontal Aviation aircraft. All aircraft can carry Sorbtsya-S active ECM jammer pods on wingtips in place of wingtip launch rails. Su-27S designation little used, but differentiates production (Series) from prototype and preproduction. Four initial production aircraft (T10-15, -17, -18 and -22) used for State Acceptance Tests were part of small initial batch featuring horizontally cropped fin caps.
Detailed description applies to the above version, except where indicated.
Su-27RV' (`Flanker-B'): Six replacement aircraft for Russian Knights aerobatic team feature GPS and Western-compatible communications equipment.
Su-27SK (`Flanker-B'): Export version of basic Su-27, using air-to-ground capabilities not exploited by Soviet/Russian Su-27s and using same weapons options and downgraded avionics. Armament, totalling up to 4,000 kg (8,818 lb), includes 250 kg and 500 kg bombs, B-8M1 packs of 20 × 80 mm rockets, B-13L packs of five 122 mm rockets, S-250FM 250 mm rockets, KMGU-2 cluster bombs, or podded SPPU-22 30 mm gun with optional downward-deflecting barrel for air-to-ground and air-to-air use. Dimensions, weights and performance generally similar to Su-27 but with reinforced landing gear giving increased (33,000 kg; 72,752 lb) MTOW. Chinese aircraft locally designated J-11, though this strictly applies only to locally manufactured examples. First Chinese-assembled aircraft flight tested in December 1998. Some later export aircraft may have upgraded radar and 6,200 kg (13,670 lb) weapon load, or even 8,000 kg (17,637 lb) according to some manufacturer's brochures.
Su-27SM: Proposed mid-life update configuration using a derivative of the Zhuk radar, AL-31FM or AL-35F engines and other improvements to avionics and hardpoints. Status unknown in 2000.
Su-27SMK: Single-seat multirole fighter based on the basic Su-27SK, and not the Zhuk-equipped Su-27SM; revealed 1995. Compared with Su-27SK, has 12 instead of 10 hardpoints; 8,000 kg (17,637 lb) weapon load; state-of-the-art nav system, including long-range radio nav, GPS, multichannel comms and latest ECM; larger internal wing fuel tanks and provision for two 2,000 litre (528 US gallon; 440 Imp gallon) underwing tanks; flight refuelling and buddy refuelling capability; retains N001 radar. Most improvements already introduced on other Su-27 series aircraft, enabling virtually full-standard Phase One Su-27SMKs to be offered for immediate delivery. These would be configured for air-to-air roles, with the new wings containing increased internal fuel, provision for underwing tanks, flight refuelling, 12 hardpoints and RVV-AE (R-77; AA-12 `Adder') AAM capability. Su-30KI demonstrator (see below) is regarded as Phase One standard. Phase Two aircraft, with improved avionics and weapon systems for air-to-surface missions, theoretically available later; weapons options to include Kh-29 and Kh-31 ASMs, plus KB-500 LGBs although this seems unlikely without much more extensive upgrade. See accompanying charts for alternative weapon loads. Dimensions as Su-27, except wing span over wingtip R-73E missiles 14.95 m (49 ft 0½ in). Weights and performance: see tabulated data.
Su-27PD: Long-endurance test aircraft with retractable AAR probe, offset IRST and recontoured tail `sting'; sometimes described as single-seat Su-30, originally Su-27P. Probably stripped of weapons system for research at Gromov Flight Research Institute and demonstration flying. Added satellite navigation; no radar or weapon control system; PC 486 with LCD for flight assessment of indication formats. At least one aircraft (3720 `598', last known Russian military Su-27); by early 1998, this was marked `Su-27 Upgrade' and undertaking development flying for Su-30KI (which see). Duties included two flights to North Pole in July and September 1999, testing SRNK satnav system. Another Su-27P (3711 `595' lacked AAR probe.
Su-30KI `(Flanker C'): The Su-30KI prototype (4002, wearing the basic Chinese dark grey colour scheme, but with a disruptive camouflage superimposed on the wings, tailplanes and outer surfaces of the tailfins) first flew on 28 June 1998, and was then sent to Chkalov Flight Test Centre at Akhtubinsk, where it was evaluated and used for launch trials of the RVV-AE (AA-12 `Adder') AAM, and for avionics and refuelling probe verification. The Su-30KI was described as a `single-seat Su-30', and was tailored to meet an Indonesian requirement, before the Asian economic crisis halted that programme. Extent to which the aircraft incorporated the `extended endurance' features of the Su-30 (apart from refuelling probe, GPS and Western VOR/DME navigation equipment) remains uncertain, however. Su-30KI also used as basis of Sukhoi's latest proposal to upgrade Russia's in-service Su-27s, replacing Su-27SM. Upgrade programme still confusingly referred to by Sukhoi as the Su-30KI, although Russian Air Forces understood to use neither the Su-30 designation nor the KI suffix.
Su-27UB (`Flanker-C'): Tandem two-seat trainer version of `Flanker-B' with full combat capability (Sukhoi designation T10U); four prototypes (first of which for static testing) built at Komsomolsk; first flown 7 March 1985 (T10U-1); series manufacture by Irkutsk Aircraft Production Association began 1986; first production UB (T10U-4) flew on 10 September 1986. Instructor in raised rear seat with 6º view forward over the nose; taller fin; length same as `Flanker-B'; overall height 6.36 m (20 ft 10¼ in), maximum combat load 8,000 kg (17,637 lb). 1,500 kg increase in empty weight, no reduction in internal fuel capacity. Export version is Su-27UBK.
Aircraft 02-01 (`Flanker-C'): Second Su-27UB flying prototype converted as inflight refuelling systems testbed with retractable probe and provision for centreline `buddy' pod; first flown early 1987. Later used in support of Su-27K and Su-27PU development programmes.
Su-27M: Advanced development of Su-27. Still the official designation for the aircraft known to the OKB as the Su-35. See Su-35
Su-27/Su-30 (Su-30KI Minor Modernisation): Proposed upgrade for export Su-27SK, bestowing same multirole standard as Su-30MKK, with inflight refuelling probe, glass cockpit, N-011M radar, GPS, VOR, DME, new mission computer, new navigation system with GPS, expanded EW and provision for new targeting pods. Development undertaken by Su-27PD 3720 `598' and, later, by Su-30KI 4002, first flown 28 June 1998. Phase I of upgrade is known in Russia as Su-30KI, despite the two-seat and Indonesian connotations of that designation. In February 1998, Su-27PD 3720 `598' was displayed at the Singapore Air Show marked `Su-27 Upgrade' and - notwithstanding the fact that it is a single-seat aircraft - stated to be undertaking development work for a variant to be designated Su-30KI. Latter is phase one of Su-27SMK programme, duties of trials aircraft 4002 including satellite-based navigation; upgraded computers; RVV-AE AAMs; Kh-29T, Kh-31P and Kh-59M ASMs; KAB-500 and KAB-1500 TV-guided bombs; and multifunction cockpit displays.
Su-27/Su-30 Major Modernisation: Proposed advanced upgrade configuration bringing any `first-generation' `Flanker' to virtual Su-27M/Su-30MKI standards, with a new MIL-STD-1553B-based avionics system, N011M radar with a phased-array antenna, and with the option of adding thrust vectoring and/or canard foreplanes.
Su-27LL-KS: Su-27 (T10-26; 0702) with axisymmetric afterburner nozzle. Also known as Su-27LLUV(KS) (Upravlyayayemy Vektor tyagi; Krugloye Soplo: thrust vector control; axisymmetric nozzle) or Su-27-KSI. Evaluated against two-dimensional nozzle testbed, described below. First flew 21 March 1989.
Su-27UB-PS: Su-27UB (Somsomolsk 0202; `08') modified in 1990 for thrust-vectoring development, with large two-dimensional box nozzle on port tailpipe. Also known as Su-27LL-PS or Su-27LL-UV(PS) (Upravlyayemy Vektor tyagi; Ploskoye Soplo: thrust vector control; flat nozzle).
Su-27LMK: CCV (Lyotno-Modeliruyushchy Kompleks: flight simulation complex) conversion of production aircraft 2405 with FADEC and side-stick, and fitted with spin-recovery rockets, tested subsequently with axisymmetric nozzle on starboard tailpipe. Trials at Zhukovsky test centre, under direction of TsIAM and Saturn/Lyulka OKB, began 1990.
Su-27LL-OS: Missile testbed; 1989 conversion of first production Su-27UB 0101 (T10U-4).
Su-27K: Described separately.
Su-27IB: Described separately.
Su-27PU: Two prototypes only; described in 1993-94 Jane's. In production as Su-30 (which see).
P-42: Specially prepared Su-27 (T10-15; first production Su-27; originally flown 2 June 1982); set 31 official world records between 1986 and 1988, including climb to 12,000 m (39,370 ft) in 55.542 seconds, and to 22,250 m (73,000 ft) with 1,000 kg (2,205 lb) payload; some records are in FAI category for STOL aircraft.

The Flanker-B always had air-to-ground capability. And the Su-27SK is exactly that... export version of Flanker-B.

Anyways, aeronautics.ru isn't an official RuAF aviation site. Rosoboronexport is.
