On Defence Minister Manohar Parrikar’s first official visit to the United States from December 7-10, Washington has signaled its willingness to co-develop with India an aircraft engine for India’s indigenous fifth-generation fighter that is called the Advanced Medium Combat Aircraft (AMCA).
India’s Defence R&D Organization (DRDO) believes it essential to work with US company General Electric Aviation (GE) in up-rating its F-414S6 engine into the so-called F-414 Enhanced Engine, which would power the futuristic AMCA.
As Business Standard reported earlier (June 1, “Carter to face Indian demand for engine technology”), GE has been eager to partner DRDO in this lucrative project. But the US government had earlier stood in the way, reluctant to transfer to India strategic technologies, such as the high-melting-point alloys needed to build the gas turbine.
During Parrikar’s visit, Washington signaled that it has changed its mind. “Secretary (of Defense Ashton) Carter informed Minister Parrikar that in light of the strengthening relationship between the United States and India, the (US Department of Defense) has updated its policy on gas turbine engine technology transfer to India. As a result of this policy update, the Secretary is confident that the United States will be able to expand cooperation in production and design of jet engine components,” says the joint statement issued on Friday by the Indian Embassy in Washington.
That opens the doors for GE and DRDO to work together in uprating the F-414S6 engine, which India has already selected for the indigenous Tejas Mark II. This will enhance the current engine’s peak power of 90 KiloNewtons (KN), delivering 110 KN of thrust. The AMCA’s twin F-414 Enhanced Engine will thus deliver an awesome 220 KM of peak power.
The green signal for co-developing this engine appears to have been given, with the joint statement saying: “Secretary Carter and Minister Parrikar look forward to US companies working with their Indian counterparts to submit transfer requests that will benefit from this updated policy.”
For GE, this could be a commercial windfall, providing it an assured market for all India’s indigenous fighters. This would include 100 F-404 engines for the Tejas Mark I, another 100 F-414 engines for the Tejas Mark II; and 400 F-414 Enhanced Engines for a planned 200 AMCAs.
Since an aero engine’s life is about 1,500 hours, each fighter – with a service life of 5,000-6,000 hours – consumes 3.5 engines. That means GE could be supplying 700 engines for the Tejas Marks I and II, and 1,400 engines for the AMCA over their service lives. This is a sizable share of the Indian aero engine market, which the DRDO estimates to be worth Rs 3,50,000 crore over coming decades.
