Russia has offered to transfer a range of Su-57 technologies to India if New Delhi agrees to purchase the fighter. However, confidence in domestic capabilities is growing within India, and calls to reject Moscow’s proposal in favor of the national fifth-generation AMCA program are becoming increasingly vocal. The Indian outlet IDRW argued that expectations that producing or co-developing the Su-57 would significantly accelerate the AMCA program are no longer realistic. According to its assessment, by the time any potential Su-57 deal materializes, AMCA will already surpass the Russian jet across all critical areas.

The publication claimed that AMCA has already overtaken the Su-57 in several key systems. It cited the Uttam Mk2 AESA radar and an integrated 360-degree sensor suite with no blind spots, which Indian analysts consider to be two generations ahead of the Russian N036 «Belka» and 101KS «Atoll» complexes used on the Su-57.

It also noted that AMCA is expected to feature a fully composite, duct-less supersonic air inlet, S-shaped intake ducts, and advanced signature-reducing coatings, allowing the aircraft to be detected only from 15–40 kilometers. By contrast, the Su-57, as the publication pointed out, has exposed compressor blades, riveted skin panels, and semi-recessed fasteners — all features that increase radar visibility and make the aircraft detectable at 60–100 kilometers.

Indian sources also drew attention to engine issues. Russia continues to promote its new «Izdeliye 30» (AL-51F1) engine, but its serial production has been halted multiple times, and it is not yet operational on any Su-57 in service. India’s own 120-kN powerplant, being jointly developed by GTRE and Safran, is expected to be certified in 2033–2034.

Analysts acknowledged that the Su-57 does retain an advantage in one area: its deeper internal bays, which allow it to carry heavier weapons internally. They argued that this is the only field where the Russian fighter still clearly outperforms AMCA.

Indian commentators concluded that the future national combat aircraft is set to dominate regardless. They believe that by the time AMCA enters service in 2035, the Su-57 — even if purchased — will be a heavier and faster platform, but one that lags technologically, amounting to what they describe as a «4.75++ generation» aircraft with limited stealth capability.
