Su-30MKI Acquisition
Su-30MKI Acquisition
Su-30MKI comprise the mainstay of IAF's fighter fleet for "air dominance."
India purchased 40 Su-30MK/MKI aircraft from Sukhoi in Russia in 1996 and acquired a license to manufacture an additional 140 MKI fighters at HAL. In 1998, it purchased an additional 10 Su-30Ks bringing the total order to 50. In January 2009, India ordered an additional 40 Su-30MKIs from Russia.

Acquisition Summary
Total Order: 230+50?
Initial Purchase (1996 and 1998) from Russia: 50
Follow-up order on Russia: 40
Initial order on HAL: 140
Additional possible order: 50
Of the initial 50 aircraft procured, 8 were basic Su-30MKs, 10 Su-30Ks, 10 Su-30MKIs with canards, and the remaining 22 Su-30MKIs with canards and AL-31FP engines, the thrust vectoring version of AL-31 engines fitted on the earlier aircraft.
The first batch of Su-30MKIs were delivered to the IAF in the beginning of 2002
The AL-31FP engine is 110 kg heavier and 0.4m longer than the AL-31F but retains the same thrust.
All the 50 aircraft acquired have since been upgraded to Su-30MKI standard.
By June 2009, HAL had assembled 42 MKIs from the total order of 140 to be assembled by the end of 2012.
Three aircraft from the follow-up order for 40 had been delivered by December 7, 2009. Delivery of the remaining is expected to be completed by 2011-12.
A total of two aircraft were lost in crashes on 30 April 2009 and 30 November 2009.
As of December 2009, the IAF is operating five Su-30MKI squadrons, with two squadrons flying HAL assembled aircraft.
India and Russia are currently negotiating a midlife upgrade for the Su-30K aircraft supplied to it earlier.
N011M BARS Radar
The Bars radar fitted on the Su-30MKI is a hybrid radar that fits between a PESA and contemporary AESA radar. It features a detection range of 76 nm (50 nm form the rear hemisphere). It has 0.9m diameter antenna The phased array can electronically steer the mainlobe through +/-70 degrees in azimuth and +/-40 degrees in elevation. The whole array can be further steered mechanically. Polarisation can be switched by 90 degrees for surface search modes.
The radar can simultaneously track both air and ground targets and engage 4 to 8 targets.
The radar can transmit targeting information to 4 other aircraft operating their radars in the passive mode.
News
In and interview to TOI on October 1, IAF Chief PV Naik indicated that the service was interested in purchasing an additional 50 Su-30 MKIs.
Indigenization
The first Su-30MKI manufactured from raw materials in India by HAL is expected to roll out in 2010, HAL Chairman V. Balakrishnan said at MAKS 2009.
HAL mastered the manufacture of the wing and the tail last year, and plans to start producing the fuselage and raw materials this year. Manufacture of the engine, the most challenging aspect of indigenization, will be undertaken in the final phase.
"We’re currently testing the locally produced engine for the Su-30MKI and are planning to launch its production in 2010."
HAL would manufacture 60 Su-30MKI fighters in the full production cycle till 2015, he said.
Russia offers Su-30MKI modernization
Russia has offered to modernize the 50 Su-30 aircraft it delivered to India under a 1996 contract.
The aircraft are due for major overhaul and Russia has proposed incorporation of the latest technologies during the major overhaul.
The project will be discussed during Defense Minister Shri AK Antony upcoming visit to Russia to attend the 9th meeting of the India-Russia Inter Governmental Commission on Military Technical Cooperation (IRIGC-MTC).
