US administration might be in process of granting an export license along with approvals for the Transfer of Technology (ToT) to General Electric conglomerate for the development of a new high-trust engine for India’s 5th generation AMCA program but the technology that will be used to develop a new jet engine based on the baseline F414-INS6 engines is already dated and will be outdated when it enters into production on AMCA Mk2 jets in 2035.

AMCA Mk2 program will revolve around a new engine that can have an “Adaptive cycle” engine, that is designed for maximum efficiency across subsonic, transonic, and supersonic flight speeds. The engine should offer Supercruise capability without engaging afterburners at 1.4 Mach and has Thermal Management (TM) to remove excessive heat without affecting its thermal signature and not reduce its efficiency in Hot-Humid Indian conditions which GE offers lacks. has been told that using baseline F414-INS6 engines might cut costs for both but won’t be capable of providing the additional power and cooling needed to support further aircraft improvements or maintain the stealthiness of the aircraft.

It’s of opinion in the engine study group in India to have a more sensible approach that is to develop a new engine that has a built-in growth margin and is modular in design so that the fighter jet can evolve to keep up with emerging threats without requiring expensive Engine Core Upgrade (ECU).

The new engine needs to be fuel-efficient and powerful while still having the ability to mask its thermal signature so that it can be used in future variants of AMCA or even in the Next-Gen fighter program that might go active in 2040 n beyond.
