India’s fighter jet engine effort has reached a decisive stage, with the Safran–GTRE joint venture for a 120 kN turbofan now before the Cabinet Committee on Security for approval, expected by 15 August 2026.
This marks the first time India will own full intellectual property in advanced propulsion, a breakthrough that could transform its airpower autonomy.
Prime Minister Narendra Modi’s 2025 Independence Day call for a home-grown fighter powered by an Indian engine has moved from rhetoric to reality. Within a year, the defence ecosystem has shifted to concrete timelines and decisions.
On the airframe side, bids for the Advanced Medium Combat Aircraft have brought TATA, Bharat Forge and Larsen & Toubro, each partnered with PSUs, into the shortlist to build India’s next-generation stealth-capable multirole fighter.
On propulsion, the Safran–GTRE joint venture has crystallised into a proposal now awaiting CCS clearance. The initial engine is planned at 120 kN thrust, with nine prototypes to be built and certified. A later 140 kN version is intended to power future fifth- and sixth-generation fighters.
India will hold 100 percent of the intellectual property, breaking from decades of dependence on Russia, France and the United States, where “hot section” technology, crystal blades and source codes were never shared.
This deal is politically and strategically loaded. India had earlier missed opportunities when France invited it to co-produce M88 engines and join the FCAS program. Instead, India continued importing Russian and French engines without sovereignty over critical technologies.
Even recent GE F404 and F414 deals, while significant, have not transferred the most sensitive know-how. The Safran–GTRE program would place India among the small club of nations—the US, UK, France and China—that can design and produce modern fighter engines.
The road ahead is demanding. Nine prototypes must undergo exhaustive testing before the design matures into the 140 kN class for AMCA and carrier-based fighters. Yet the fact that a credible, IP-owned program is on the table is a defining moment.
The engine will feature advanced technologies such as single-crystal turbine blades, high turbine entry temperatures above 2,100 Kelvin, FADEC systems, and a variable-geometry afterburner to reduce infrared emissions and improve efficiency. This directly enhances survivability against modern air-defence threats and positions the AMCA MK-2 as a formidable fifth-generation fighter.
China’s propulsion leap underscores India’s urgency. Beijing reverse-engineered Russian and American engines before fielding the WS-10 and WS-15, the latter a 180 kN class engine powering the J‑20.
These fighters are already deployed across Tibet opposite Arunachal Pradesh, giving China genuine long-range air combat capability. Gupta warns that India cannot afford PSU delays and must embrace faster decision-making and tighter timelines.
India’s engine strategy is diversified. The original Kaveri engine stalled at 40 kN but has been revived with an 80 kN target as a technology demonstrator. Parallelly, India remains tied to US engines in the near term.
A contract for 212 GE F404 engines supports the TEJAS MK-1A fleet, though deliveries face supply chain delays. More strategically, the GE–HAL joint production of F414 engines for Tejas Mk2 and initial AMCA squadrons promises 70 percent technology transfer, but again without source codes or crystal blade technology. Reform within HAL is essential to meet timelines.
The broader debate extends beyond engines. India has no operational fifth-generation fighter, while China flies the J‑20. Options like the US F‑35 or Russia’s Su‑57 are under discussion, but the Iran–US war has shown the vulnerability of stealth aircraft to advanced missiles.
This raises questions about investing scarce capital in manned stealth fighters versus longer-range standoff missiles and unmanned combat air systems. Missiles and drones are already central to modern warfare, and India’s private sector is driving a revolution across engines, aircraft and missiles.
Against this backdrop, the Safran–GTRE engine is more than a technical project. It is a test of whether India can cross the gold standard of jet engine design, achieve strategic autonomy in airpower, and reshape its force structure for an era where stealth, standoff and unmanned systems coexist uneasily on contested battlefields.
