Russia Offers India 177S Engine for Super Sukhoi Fleet Upgrade
Russia has offered India a newer engine for some of its Su-30MKI fighter jets.
The proposal is part of a much larger plan to modernize nearly 260 aircraft.
The first part of the plan could involve 84 jets.
Russia says the new engine is powerful, lasts a long time and could use less fuel.
It is similar in size and weight to the engines already used in the fighters.
That could make installing it easier, but India still needs to study the idea.
The modernization may also add better radar, computers and electronic defenses.
Russia has made other defense offers, including Su-57 fighters and more air-defense systems.
India will decide after examining the technical, financial and industrial issues.
Russia has offered its Izdeliye 177S engine for India’s Su-30MKI fighter fleet.
The proposal is part of the estimated $11-billion Super Sukhoi upgrade programme for nearly 260 aircraft.
The initial upgrade phase is expected to cover 84 Su-30MKIs and include new radars, avionics and electronic-warfare systems.
Russia says the 177S can provide up to 14.5 tonnes of thrust, last up to 6,000 hours and reduce fuel consumption by about 7%.
India will need to assess technical integration, costs, technology transfer and local-production opportunities before deciding.

Indian Evaluation
India must assess the technical requirements before deciding whether the engine can be integrated into the aircraft.
Modernization benefits
Russian Proposal
Russia reports that the engine could provide up to 14.5 tonnes of thrust, last up to 6,000 hours and reduce fuel consumption by about 7%.
Indian Evaluation
These reported benefits would need to be weighed against cost, technical evaluation, technology-transfer terms and the potential for local production.
Broader defense cooperation
Russian Proposal
Moscow is also proposing joint production of Su-57 fighters, additional S-400 systems, the S-500 system and an S-400 maintenance facility in India.
