Russia has made another proposal to India on building an advanced fighter engine for upgrading the fleet of the Su-30MKI aircraft of the Indian Air Force. This proposal came as part of President Vladimir Putin’s trip to New Delhi to participate in the BRICS summit. The Izdeliye 177S engine might be installed to replace the current engines AL-31F/FP on the fighter.
What Is the 177S Engine?
According to Russia’s proposal, the 177S engine will be capable of producing 14.5 tonnes of thrust with the dimensions and weight similar to those of the current engines AL-31F/FP.
This feature will allow installing the power plant in Su family aircraft without significant changes in their designs. Increased efficiency and durability are emphasized as main benefits of the engine.
According to Russian information, the engine can operate up to 6,000 hours and will help to reduce the consumption of fuel by about 7%.
Reasons for Russia Pitching the Engine to India
One reason why Russia could be pitching the engine to India is the fact that India uses a significant number of Su-30MKIs whose operational success will depend on the performance of the engine and maintenance considerations.
Moreover, the pitch of the engine is based on the previous collaboration of Russia and India in aerospace technology. The Hindustan Aeronautics Limited currently produces and maintains AL-31FP engines.
The pitch by Russia to India will still have to be evaluated based on various technical and operational considerations before any decisions are made.
Considerations about Costs and Operational Issues
The pitch by Russia on the 177S is not an upgrade that India must undertake automatically.
India will have to look at the economic implications of using the new engine and the various requirements for integration and maintenance, amongst other considerations.
This consideration can determine how the pitch by Russia will be accepted or how it can be limited in some ways.
The pitch is made at a time when both nations are holding talks about the Su-57E which is the export version of the fighter aircraft of Russia.
Defence Ties between India and Russia
The engine deal is part of wider initiatives to reinforce the strategic ties between India and Russia. In the course of his visit to New Delhi, President Putin and PM Modi agreed to enhance defence and technological collaboration.
Also, there have been attempts to boost trade ties between India and Russia, aiming to take the annual trade volume to $100 billion by 2030.
