New Delhi: A comprehensive upgrade of the mainstay Su 30MKI fighter jet fleet that will see the aircraft get new radars, mission control system, electronic warfare capabilities and integration of new weapon systems will see heavy participation from the private sector.

The $7.5 billion upgrade, approved by the defence ministry last year, will be done by Hindustan Aeronautics Limited, with support from the Defence Research and Development Organisation (DRDO) and several major components will be procured from the Indian private sector.

"The upgrade will see significant private sector participation, with HAL as the lead integrator," CMD of HAL CB Ananthakrishnan told ET.

The project, which has been put on fast track by the Indian Air Force, is to be carried out in two phases. The first will involve new avionics and radars for the aircraft while the second phase will concentrate on flight control systems. Several Russian origin systems are being replaced by indigenous options.

A majority of the work will involve indigenous systems that are to be fitted onboard the platform to give it a combat edge. This will include a new indigenous radar that will enable the aircraft to pick up and engage targets at much larger distances. The radar in older generation jets had been a point of concern for the Air Force as it would get outperformed by systems used by adversaries.

In the first phase, the aircraft will also get a new Electronic Warfare System to jam incoming threats and disrupt enemy communication. Besides, the fighters are to get new indigenous Infra Red Search and Track systems that will greatly enhance the ability to engage air-to-air and air-to-ground targets.

Work on integrating the aircraft with the new systems could begin this year, with the Air Force keen on modernising the entire fleet at the earliest. Close to 90 of the fighters are to be upgraded in the first tranche that would be conducted entirely in India.

India ordered 272 of the fighter jets from Russia that form the mainstay of the Air Force fighter fleet. Last year, an order for 12 more jets was also cleared for Rs 11,000 crore. These jets would be manufactured by HAL with indigenous content of over 50%.

Over 600 aircraft of the Su 27/30 type have been manufactured and large operators include Vietnam, Malaysia, Indonesia and Algeria. This opens up a significant export market for the upgrades as well.

Former Indian Air Force (IAF) pilot Vijainder K Thakur told The EurAsian Times, “The Long Range Dual Band Infrared Imaging Search and Track System (IRST) for SU-30 MKI being developed by HAL & BEL will feature Focal Point Array (FPA) sensors in two bands. It will facilitate improved target recognition and better discrimination of the target from background IR radiations.
“Typically, a dual-band IRST would operate in the 8-12 µm LWIR band and 3-5 µm MWIR band. Hot objects such as exhaust ports and engine plumes are more pronounced in the MWIR, while airframes, fuselages, and missile hard bodies are more pronounced in the LWIR. Water vapor absorption dominates in the LWIR, while carbon dioxide absorption dominates in the MWIR. Solar reflections are significant in the MWIR but suppressed in the LWIR,” according to Thakur.

 
7.5 billion USD to upgrade 84-90 Su30MKI , Thats 85 MIL USD per unit is on the expensive side considering that most of the upgrades are from domestic source

even brand new SU35K with all of the above upgrades would have cost us not more than 110 million USD

Because of the R&D cost
Initial batches of every system includes R&D , that's why so expensive
 
India should have used the SU-30MKIs as the basis for its future fleet, much like the way the PLAAF has done. The Chinese created a totally new line of fighter jets based on the Sukhios but with much advanced capabilities. India on the other hand, spent decades trying to decide which aircraft to import and in the end the LCA aircraft is still not widely inducted.

A lot of it has to do with budget and fleet requirements, PLAAF has/ requires 1500 fighters, for them having 500 J11/J16 / SU27/SU35 is no big deal.

Indian airforce requirements are centered around a 700 fighter force, so their fighter mix is going to be a lot different
IAF hopes to cut down the mix to just 3-4 different fighters by 2035


Indian Airforce doctrine calls for Heavy medium and Light Fighter mix

Heavy fighters bring in long range and higher payload , but they are also expensive to fly and maintain
That role is played by Su30MKI in IAF

Medium weight fighters like the Rafale , Typhoon can carry similar payload to heavy fighters but have shorter range
but they have advantages like far lower RCS , lower running and maintenance cost, they can also take off from high altitude airbases with decent payload due to their lower weight
Thats why you see Mig29UPG, Mirage 2000 and Tejas performing Combat Air Patrol missions in Ladakh .

Light fighters like Tejas, JF17, TF50 have a small weapons payload and lower range, but they are also cheaper to buy and Operate and can make up squadron numbers while providing decent capabilities in point defence and CAP

Under Ideal conditions India would like to field
270 Su30mki in heavy category across 13 sqds
150 Rafale F4/5 in medium category across 7-8 sqds
340 Tejas MK1A/B/2 in light category across 17 sqds

With AMCA replacing older su30s post 2037

India is not going for many variants of same weight class. It is mainly focusing on light - LCA, Medium - Rafale (indigenised with Kaveri engine and LCA avionics & equipments), Heavy - Su30, stealth - AMCA & Naval - TEDBF. Basically 4 variants for airforce & 1 variant for navy is all India is seeking.
India does not intend to have plethora of heavy planes. PLAAF has plans for mostly heavy planes with only J10 being medium ones. This is likely due to India not being rich in petroleum reserves and hence not intending to waste fuel during wartime where not needed
 
I am guessing a portion of the upgrade includes the new engines which will eat up a far a amount of the cost. Dropping Russian avionics is one of the best decisions for India. Russia has never been good at avionics and India right now has more software engineering capabilities than Russia anyway right now.

The Su30MKI is quite flawed now for the era of warfare we are in with its massive elephant size RCS values - the best that India can do is to use up their capabilities as they are for that paid for and see what its next set of options are.

Engine upgrade isn't all that necessary.
These new gen sensors are quite power efficient.
