Moscow has presented India with what it calls an “irresistible” offer.
Russia has renewed its pitch to India for the Su-57E, offering not only the fifth-generation fighter jet but also unprecedented access to its source code.
Reported by BulgarianMilitary.com, the proposal aims to give India full autonomy over modifications, integration of local weaponry, and maintenance—something the U.S. does not offer with the F-35.
The offer was made public shortly after the Su-57 was showcased at the Aero India 2025 trade fair, in a move to counter India’s increasing defense diversification.
Traditional Defense Partners
While Russia has been India’s main defense supplier for decades, that dynamic is shifting, according to WP Tech.
India now acquires arms from multiple sources, including NATO members.
French Rafale jets are already in service, and Washington has openly floated the possibility of selling the F-35 to India—first mentioned by Donald Trump earlier this year.
At the same time, New Delhi is considering the development of a fully domestic fifth-generation fighter, a move that would give it strategic independence in the long term.
What Russia Is Really Offering
The Su-57E, Russia’s export version of its most advanced fighter, features a top speed of over 2,100 km/h, ceiling of 20,000 meters, advanced radar, and multiple weapons configurations.
But the standout feature in this deal is access to the aircraft’s source code, which would allow India to independently upgrade systems and integrate indigenous technology.
That level of control is not standard in international arms deals. F-35 buyers, for example, must rely on the U.S. for software updates and integration, limiting operational flexibility.
Analysts remain skeptical of the Su-57’s stealth capabilities, and some question whether it fully meets fifth-generation criteria. Development delays and reliability issues have also affected its image.
Still, the offer puts pressure on Indian decision-makers. The chance to operate an advanced fighter on their own terms may outweigh the risks.
