Development

The original Su-27IB prototype was initially described by the Sukhoi OKB as “Su-27KU” (korabelnyi uchebno: shipborne trainer) and described as a carrier trainer, despite the lack of an arrester hook, folding wings, a strengthened landing gear and a carrier landing system. The aircraft did make dummy carrier approaches, and may have flown from the dummy deck at Saki airbase to evaluate the suitability of the new cockpit for carrier operation. The naval strike Su-32MF may once have been intended for carrier operation. The need for a dedicated trainer for the Su-33 became increasingly clear, and the development of the T10KM-2-based Su-27KUB (korabelnyi uchebno boevoi: shipborne fighter trainer) with the Sukhoi OKB model designation T10KU began in the late 1990s. It was formally acknowledged 21 October 1998. It is probably developed as a private venture, with no firm commitment from the Russian Navy. It is/was likely to become the Su-33UB, following the redesignation of the carrierborne single-seat Su-27K to Su-33.
[edit]
Prototypes

Three prototypes were built, with noses built by KnAAPO, as T10KU-1, -2, and -3, and incorporated lessons learned from the Kuznetsov's 1996 Mediterranean cruise. The construction of T10KU-1 began in 1998 mating a new nose and new wings and tailplanes to an existing T10K prototype (T10K-4). It was powered by AL-31F engines and the aircraft first flew on 29 April 1999 and made it’s first arrested landing on the dummy deck at Saki, 3 September 1999. The first take-off from the deck ramp followed on 6 September. The first landing and take-off from the “Admiral of the Fleet Kuznetsov” were performed on 6 October 1999. T10KU-2 and -3 were reported to be under construction in 1999, perhaps using new-build airframes, but had not been seen by January 2001. T10KU-1 was test flown by Indian pilots, September 1999, but the Su-27/Su33 was judged too large for the planned Indian Navy carriers. A further series of tests at Saki begun December 2000.
[edit]
Production

Any production is likely to be by KnAAPO. The basic variant due to be extrapolated to produce trainer, reconnaissance and AEW versions, the last-mentioned with a phased-array mounted on the spine, between the composites antenna tailfins. Increased thrust, thrust-vectoring AL-31FP, AL-31FM or AL-41F engines mooted for production version.

Su-30K-2

A two-seat interceptor version based on the Su-33 fuselage was under construction at Komsomolsk in late 1999. It was due to fly late 2000.

Technical information

Design Features

The aircraft has navalised features of the Su-33, including folding wing (with the fold further outboard and with a larger fold angle). Some sources suggest that the Su-33UB's tailplanes do not fold, since they reach only as far as the new outboard wing fold. Double slotted flaps, unslotted, “adaptive” leading-edge, arrester hook, datalink and carrier landing system. However, compared with the Su-27IB, the forward fuselage is slightly narrower, with the seats closer together and it has a much less pronounced dorsal hump. New “glass cockpit” with five colour LCD displays (one 53 cm or 21 in diagonally; the rest is 38 cm or 15 in) with provision for central or sidestick and with helmet-mounted sighting system. The aircraft has OBOGS and OBIGGS and so does not need oxygen or nitrogen bottles. N014 solid-state, phased-array radar, with enhanced air-to-ground and over-water capabilities, planned eventually, but the prototypes have either ballast or the Zhuk-MS and the production aircraft may initially use the NIIR N610-27 (Zhuk 27). Circular-section radomes replace flattened “latypus” nose associated with the Su-27IB. Some reports suggest that the Su-33UB's new wing is 12 per cent larger in span (about 16 m or 52½ ft) and area (about 70 m2 or 750 sq ft), as are the canards and tailplanes. The production Su-27KUB will feature a higher set, square-section, lengthened tail-sting, possibly mounting rear warning radar. The tailcone folds (upwards) to reduce stowed length, but the prototypes have the standard Su-33 tailcone.
