India’s S-400 purchase from Russia could trigger CAATSA sanctions that may affect the supply of American General Electric F404-GE-IN20 and F414-INS6 that are been selected to power India’s Tejas Mk1/1A and LCA-AF Mk2 Program, but a senior ranking official from India’s state-owned Hindustan Aeronautics Limited (HAL) official who spoke to on condition of anonymity said that they’re in touch with Aerospace engine maker GE over this and are working out deliveries of future batches of engines (F404-GE-IN20) to be used on the recently ordered 83 Tejas Mk1A and it’s unlikely they will be disruption in supply due to CAATSA.

Indian Air Force (IAF) and HAL officials who regularly meet have not discussed this matter and for the time being no alternative engines for the Indigenous fighter jets have been planned or considered as speculated on some section of the media. When asked if Indigenous Kaveri Dry engine with Afterburner section that is under development for the unmanned combat aerial vehicle (UCAV) program can be used to power Tejas Mk1A, was told Kaveri engine has been delinked from the LCA-Tejas program due to insufficient generation of power from the engine and the engine still can’t generate required thrust to be considered as an option for the LCA-Tejas Mk1A program.

Kaveri Dry engine can generate only 46kN class of thrust that if added with an afterburner section power generation jumps to 74kN class of thrust, just not enough power or replace present F404-GE-IN20 engines that generate 84kN Thrust class when afterburner is engaged. GTRE is currently developing 4 Prototypes of the Kaveri Dry engine to be used for the UCAV program, but it is still 3-4 years away from being cleared for production. When asked if M88-3 engines used on Dassault Rafale can be used on the LCA-Tejas Mk1A program if the need arises, was told that M88-3 engines are not cleared to power single-engine fighter class of jets and it could require several minor changes and hardening of some sections by the Safran so that it can have a higher tolerance to damages and improved safety measures before it can be considered, same way F414 engine had to undergo changes and additional safety measures added for operations from single-engined LCA-AF Mk2 Program.
