China’s recent agreement with Russia to acquire 24 Sukhoi Su-35 aircraft is of interest to New Delhi as it would face off against India’s Sukhoi Su-30 MKI fighter in any contingency planning by the air forces of the two countries.
The Su-30 was a top-line fighter aircraft when it was procured by India and will be beginning the season of upgrades soon. The brand new Su-35 may be a notch higher. Even though after its upgrade, the Su-30 MKI would have the specs of the next version of the Su-35, possibly a Su-36, aviation experts believe.
The similarities between the present Su-30 MKI and the Su-35 are they carry 12 hard-points, besides 8,000 kgs of external ordnance, pulling a maximum of 9G. They have the same air-to-air and air-to-ground weapons package; have thrust vectoring engines and can house external jammers of all varieties and all kinds of pods.
This is where the similarities end and the differences begin. The Su-35 carries maximum internal fuel capacity of 11,500 kgs, while the Su-30 MKI has 9,640 kgs. In terms of operating range, there is a difference of a mere 600 kms: Su-35 with 3,600 kms and Su-30 MKI with 3,000 kms. The max altitude they could climb is 17.3 kms (Su-30 MKI) and 18 kms (Su-35); and max speed (Su-30 MKI) – 1.9 Mach and Su-35 – 2.25 Mach (this is a crucial difference in case of a dog fight on after-burners).
The Su-30 MKIs canards are a necessity because of its heavy IRBIS radars (Phased Electronically Scanned Array Radar – PESA), while the Su-35 do not need canards as its radars are lightweight.
The Su-30 MKI is a two-seater, while Su-35 is a single seater multirole aircraft.
Indian variety of the Su-30 cannot carry external fuel tanks, while Su-35S has two of them - each drop tank carrying 1400 kgs.
The Russian Su-35, which the Chinese have signed an agreement to buy two dozens of them have extensive use of composite material; while Su-30 MKI has very little composite materials in its fuselage or wings.
Two important factors should be kept in mind in terms of their operational deployment; while Su-30 MKI has a rather large radar cross section (RCS) in comparison to the Su-35 while the latter can track and engage more targets.
According to retired air marshal Sumit Mukerji of the Indian Air Force, “the progressive evolvement of the SU-27 Flanker through the SU-30 model and the Indian variant, the SU-30 MKI, with state-of-the-art technologies embedded, allowed the Russians to step up from 4th Gen to the 4++ Gen smoothly with the creation of the SU-35. From the data available on the aircraft, it's capabilities both in terms of performance and armament, the SU-35 is obviously a step ahead of the SU-30 MKI, but not by much.”
“Notwithstanding the edge, the SU-35's ability to operate from relatively forward airfields at high altitude such as in the Tibetian plateau will certainly be curtailed in terms of quantum of armament. So, at near parity in performance, two factors will determine who will come out best -- the on-board avionics and the pilot(s) with his professional training,” he added.
Russias United Instrument Manufacturing Corporation (UIMC) will begin supplying China with communication systems for its newly ordered Sukhoi Su-35 jet fighters from next year. This is the first confirmation from a Russian agency giving an indication of the approximate delivery of the aircraft systems to China
Russias sale of 24 Sukhoi Su-35 to China for US$200 million works out to approximately US$83 million per unit, a bargain price compared to some of the Western origin front line fighter aircraft in the world. In comparison, the French Rafale cost approximately US$200 million apiece in recent contracts with Egypt and Qatar and a figure close to that in an expected contract with India
Russia has signed a contract with China to sell 24 Sukhoi 35 multi role fighter aircraft worth US$ 2 billion. Russias state technologies corporation, Rostec head Sergey Chemezov announced that Russia and China have signed a contract, estimated to be worth $2 billion, on the delivery of 24 Russian Sukhoi Su-35 fighter jets
India has test fired its home-made nuclear nuclear capable Prithvi-II Missile that has strike range of 350 km. The test conducted today is part of a user trial by the army and was carried out from a mobile launcher from launch complex-3 of the Integrated Test Range (ITR), Economic Times reported Thursday
India and Malaysia will set up a Sukhoi Su-30 aircraft forum to exchange information on training, maintenance and technical support for the Su-30 fighter aircraft fleet in each others air force. The launch of the forum was announced during a joint press conference by the Indian Prime Minister Narendra Modi and his Malaysian counterpart in Kuala Lumpur today
