Will India Accept Su-57 Downgraded Export Version?

The Sukhoi Su-57 and its export variant, the Su-57E, look identical externally but possess critical internal differences. Russia designed the domestic Su-57 for its Aerospace Forces with highly classified avionics and top-tier sensor fusion. Conversely, the Su-57E is tailored to protect sensitive technology while meeting international export controls.

One major distinction involves electronic warfare suites and radar signature suppression. The export model features adjusted electronics and software to prevent foreign access to guarded source codes. Furthermore, the Su-57E features a customized cockpit where displays use English and instruments read in imperial units instead of metric readings. The export version also boasts flexible architecture. This open design allows buyers to integrate non-Russian weapons and communication systems seamlessly into the stealth platform. These careful adaptations make the advanced fighter incredibly marketable globally.
