Verdict: India still has no in-production fighter jet engine of its own, and of the three tracks now running, the GE F414 licence build is the only one certain to put new engines into Indian fighters before 2030. HAL and GE Aerospace agreed the technical terms for F414 co-production in April 2026, and reporting points to a signed contract by December 2026 (Aviation Week, 14 April 2026; idrw.org). The Safran-GTRE programme, a 120 kN engine India would fully own, is the bigger strategic prize, but it was still awaiting Cabinet clearance as of early September 2026. The indigenous DRDO Kaveri posted its strongest thrust yet in a February 2026 afterburner test, yet no production aircraft is waiting for it. A kilonewton (kN) is the standard unit of jet engine thrust; an F404-class engine produces about 80 kN with its afterburner lit.
TL;DR
- GE F414 (licence build with HAL) - technical agreement reached April 2026, roughly 80% technology transfer reported, final contract expected by December 2026, HAL line targeted to be ready about two years after signing (Aviation Week; idrw.org).
- Safran-GTRE (co-development) - a 120 kN engine for the AMCA Mk2 with 100% Indian intellectual property, including hot-section technology; the proposal sits with the Cabinet Committee on Security and no clearance had been announced as of early September 2026 (Hindustan Times, 11 September 2025; Indian Masterminds, 5 August 2026).
- Kaveri (indigenous) - a full afterburner test on 16 February 2026 with a new afterburner designed to push the engine to about 81-83 kN, and flight trials on a Tejas testbed planned by 2030 (DRDO; idrw.org, 18 June 2026).
- Why all three exist: the F404 import mess. Only about nine of the 212 F404 engines India has ordered had arrived by early August 2026 (Hindustan Times, August 2026).
- Last verified: 10 September 2026.
Which jet engine does India use today?
Imported or licence-built foreign engines power every fighter India flies. The Tejas Mk1A runs the American GE F404-IN20, which produces 53.9 kN dry and 82 kN with afterburner (AeroTime, 20 June 2023). The Su-30MKI fleet runs the Russian AL-31FP, which HAL's Koraput Division licence-builds under a Rs 26,000 crore Ministry of Defence contract for 240 engines signed on 9 September 2024 (PIB). India's 36 Rafales fly the French Safran M88 (Hindustan Times, 11 September 2025).
That dependence bites because the air force is shrinking. The IAF is down to 29 operational fighter squadrons against a sanctioned strength of 42.5, even as Pakistan fields Chinese J-10Cs and China expands its stealth fleet (The New Indian Express, 26 June 2026). Engine supply, not airframe production, is the binding constraint on fixing it. For a company-by-company view of who actually builds engine hardware in India, see our comparison of India's jet engine manufacturers, from HAL to GTRE.
What is the GE F414 deal and when will HAL build it?
It is a licence-production agreement: HAL builds GE's F414 in India for the Tejas Mk2 and the first two AMCA squadrons, without owning the design. GE and HAL "reached an agreement on technical matters" in April 2026 after nearly three years of negotiation, and the final contract is expected to be signed by December 2026 (Aviation Week, 14 April 2026; idrw.org). India plans to produce 99 engines in the first tranche against an IAF requirement of 120 to 130 Tejas Mk2 fighters (Indian Defence News, 27 April 2026).
The 2023 MoU was billed as about 80% technology transfer (The Indian Express, June 2023); more recent reporting suggests the final package may land closer to 70% (Hindustan Times, August 2026). Either figure would be the deepest fighter-engine transfer Washington has ever approved, but neither is design ownership. The F414-INS6 is slated for the Tejas Mk2, the deck-based TEDBF and the AMCA Mk1 (The Hindu, 22 June 2023; The Economic Times, 16 April 2026).
The F404 saga explains India's urgency. HAL ordered 99 F404-IN20 engines in a Rs 5,375 crore ($716 million) contract in 2021 (The New Indian Express, 26 June 2026), yet the first engine reached HAL only in March 2025 and just six had arrived by June 2026, with one failing acceptance checks (The New Indian Express, 26 June 2026). HAL began imposing contractual liquidated damages on GE, per engine, for every late delivery (India Today, 3 April 2026). The seventh engine arrived in mid-July 2026 (India Today, 13 July 2026), GE said it shipped three more in August (Livemint, 3 September 2026), and it has committed to 20 engines between June and December 2026 (Livemint, 3 September 2026). India added 113 more F404s in a Rs 8,300 crore ($1 billion) November 2025 follow-on for 97 additional Tejas Mk1A (The New Indian Express, 26 June 2026). With 180 Mk1A on IAF order, every slipped engine delivery slips a jet (Livemint, 3 September 2026).
Where does the Safran-GTRE 120 kN engine stand?
Awaiting Cabinet Committee on Security clearance, with no approval publicly announced as of early September 2026. The plan, as reported: Safran and DRDO's Gas Turbine Research Establishment co-develop a 120 kN engine in India, build nine prototypes within a 12-year frame, uprate it to 140 kN later, and hand India 100% of the intellectual property, including single-crystal turbine blade technology (Hindustan Times, 11 September 2025). Safran chief executive Olivier Andries has described it publicly as "a complete transfer of technologies", covering the critical hot section (The Economic Times).
Cost reporting diverges sharply and no government figure exists: the programme has been reported at around Rs 20,000 crore (idrw.org), while Safran's own chief executive has spoken of roughly ₹610 billion over a decade and more, about $7 billion at current rates (Quwa, 4 August 2026). Treat both as estimates until a contract is signed. If timelines hold, production could begin around 2036 (Indian Masterminds, 5 August 2026). GTRE is already building a 130 kN-class twin-cell test bed at Rajanukunte near Bengaluru, sized for both the dry Kaveri and the 120 kN AMCA engine (Quwa, 4 August 2026).
The engine would power the AMCA Mk2; the Mk1 flies on the GE F414 under the AMCA programme's Rs 15,000 crore March 2024 approval (Quwa, 4 August 2026). Rolls-Royce is the rival suitor: with Reliance Industries it announced a strategic intent to partner on an indigenous AMCA engine on 14 August 2026 (Rolls-Royce), and its proposal targets core testing in 2030, first flight in 2034 and production in 2036 (Aerospace Global News). We compared the two suitors in detail in the Safran vs Rolls-Royce AMCA engine contest.
Is the Kaveri finally close to a real fighter engine?
Closer than it has ever been, but still not in an aircraft. The programme launched in the late 1980s and was delinked from the Tejas in 2008 after producing about 70.5 kN wet thrust against a requirement near 81 kN; 11 development engines and four Kabini cores were built across the programme (Wikipedia, GTRE GTX-35VS Kaveri).
February 2026 marked the strongest result yet. Defence Minister Rajnath Singh visited GTRE in Bengaluru on 16 February 2026, reviewed the programme and witnessed a full afterburner test (DRDO newsletter, February 2026). The test used a newly designed afterburner section developed with BrahMos Aerospace, aimed at pushing the engine to about 81-83 kN (Times of India). Singh used the visit to set a five-year deadline for indigenous next-generation engines, saying India must achieve in five years what other countries take 20 to do (DRDO newsletter, February 2026).
The near-term flight plan is modest. GTRE intends to fly the current about 73 kN afterburning configuration first, on a modified older Tejas LSP airframe by 2030, before maturing an 84-85 kN version (idrw.org, 18 June 2026). The non-afterburning Kaveri Derivative Engine, at roughly 49-51 kN, has been approved for in-flight testing on a Russian Il-76 testbed and is intended for the Ghatak stealth drone (Wikipedia, GTRE GTX-35VS Kaveri). The revival's backstory, and how it fits the push against GE's effective monopoly, is in our Kaveri 2.0 programme explainer.
Which engine track wins, and for whom?
| Track | Engine | Thrust | Status, September 2026 | First Indian-built engines | What India gets |
|---|---|---|---|---|---|
| Licence build (GE + HAL) | F414-INS6 | 98 kN | Technical terms agreed April 2026; contract expected December 2026 | About 2-3 years after contract | ~80% ToT reported, no design IP |
| Co-development (Safran + GTRE) | New clean-sheet engine | 120 kN, growing to 140 kN | With the CCS; no clearance announced | Production reported around 2036 | 100% IP including hot section |
| Indigenous (DRDO/GTRE) | Kaveri | 81-83 kN tested with afterburner | Ground testing; flight trials planned by 2030 | Uncertain | Full design and production sovereignty if certified |
If you need engines this decade, the F414 wins: it is the only track with a defined production start, and the only one that already powers a flying Indian prototype programme. If you are betting on strategic autonomy, the Safran-GTRE engine wins: full IP on a 120 kN design is something no US or Russian offer has ever matched, and it is the track that changes India's position rather than its supply chain. If you are watching Indian engineering itself, the Kaveri is the story: an 81 kN-class afterburner test is a real result for a programme written off in 2008, but a testbed engine in 2030 is not a fleet engine.
The honest ranking for the next five years: F414 delivers, Safran-GTRE decides, Kaveri learns. HAL said in February 2026 that nine Tejas Mk1A airframes stood ready with engines awaited (DRDO newsletter, February 2026) - that gap between airframes and engines is the entire jet engine problem in one sentence.
What this means for you
Licence manufacture without design IP is assembly, not autonomy. The F414 deal transfers an unprecedented share of manufacturing know-how, but GE keeps the design; the ultra-high-end core metallurgy may stay imported in the early years (idrw.org). The distinction to watch across all three tracks is IP ownership, and it separates the F414 from the Safran-GTRE engine more sharply than thrust figures do.
Three checkpoints will tell you how this resolves: the F414 commercial contract, targeted by December 2026 (idrw.org); the CCS decision on Safran-GTRE, expected but not announced as of early September 2026 (Indian Masterminds, 5 August 2026); and the Kaveri's first flight on the Tejas testbed, planned by 2030 (idrw.org, 18 June 2026).
FAQ
Q: Does India make its own jet engine?
A: Not in production. HAL licence-builds the Russian AL-31FP under a 240-engine contract (PIB) and will licence-build GE's F414, but India owns the design of neither. GTRE's indigenous Kaveri has produced 11 development engines since the late 1980s and no production engine (Wikipedia, GTRE GTX-35VS Kaveri).
Q: What is the most powerful engine programme in India?
A: The Safran-GTRE co-development: a 120 kN engine planned for the AMCA Mk2, to be uprated to 140 kN, with nine prototypes in a 12-year frame (Hindustan Times, 11 September 2025).
Q: When will HAL start building the GE F414 in India?
A: After the commercial contract, which reporting expects by December 2026. HAL and GE have compressed the facility setup from three years to two, with the line in Bengaluru (idrw.org).
Q: Why is the Tejas Mk1A so late?
A: Engine supply. GE had delivered only six of the 99 F404-IN20 engines ordered in 2021 by June 2026, one of which failed acceptance checks, leaving HAL with completed airframes and no engines (The New Indian Express, 26 June 2026).
Q: Can the Kaveri engine power the Tejas?
A: Not today. Its new afterburner targets about 81-83 kN (Times of India), comparable to the F404-IN20's 82 kN with afterburner (AeroTime), but flight trials on a Tejas testbed are only planned by 2030 and no production aircraft is committed to it (idrw.org, 18 June 2026).
Q: Who decides which engine the AMCA gets?
A: The Cabinet Committee on Security. The Safran-GTRE proposal for a 120 kN engine is before it now, with clearance reported expected before 15 August 2026 but not officially announced (Hindustan Times, August 2026; Indian Masterminds, 5 August 2026).
