To meet the 2026 deadline, the GTRE is preparing for a rigorous testing campaign.

A key phase involves high-altitude trials in Russia, where the engine will be mounted on an Ilyushin Il-76 flying testbed.

These trials are essential to validate the engine’s performance, restart capabilities, and stability in the thin air and freezing temperatures of high-altitude flight—conditions the Ghatak will face during operational sorties.

India is handing Russia access to engines it desperately needs for war.
