GE Engine Shortfall Stalls India’s Tejas Mk1A Fighter Rollout
New Delhi has begun fining General Electric over years of delayed jet-engine deliveries that are holding up India’s most important fighter program, even as the two sides work through a supply crunch that has left dozens of finished Tejas Mk1A airframes sitting on Hindustan Aeronautics Limited’s assembly floor without an engine to fly.
What Happened
Hindustan Aeronautics Limited (HAL), India’s state-owned aerospace manufacturer, has invoked liquidated-damages penalties against GE Aerospace under a 2021 contract for F404-IN20 engines that power the Tejas Mk1A light combat aircraft, after the U.S. engine maker missed successive delivery deadlines by more than two years. HAL’s then-chairman, Dr. D.K. Sunil, confirmed the penalty clause was being enforced in early April 2026, telling reporters the contract “includes a provision stating that if there is a delay in the delivery of F-404 engines… liquidated damages will be imposed on GE Aviation.”
By that point HAL had received only six of the 99 engines ordered in August 2021, against roughly 30 completed Tejas Mk1A airframes waiting on the production line for a powerplant, according to Indian defense trade reporting. GE has since accelerated shipments: a seventh engine was handed over on July 8, 2026, and a batch of three more arrived in August 2026, bringing the cumulative total delivered to around ten. GE Aerospace has told HAL it is committed to delivering 20 engines in the second half of 2026 and to sustaining an annual output of 24 to 26 engines from this year onward.
Separately, on April 13, 2026, GE Aerospace signed a contract with the Indian Air Force to help establish an in-country maintenance depot for the F404-IN20, intended to let the IAF overhaul engines domestically rather than shipping them abroad — a step aimed at cutting turnaround times once the fleet is flying in numbers.
The Product/System
The Tejas Mk1A is the latest production variant of HAL’s single-engine, delta-wing Tejas light combat aircraft, India’s indigenous answer to aging MiG-21, MiG-29 and Jaguar squadrons. It adds an AESA radar, an integrated electronic-warfare suite, beyond-visual-range missile compatibility and in-flight refueling over the earlier Tejas Mk1, while retaining the airframe’s roughly 64% indigenous content on the current order.
Power comes from General Electric’s F404-IN20, an India-specific variant of the F404 turbofan rated at roughly 84 kilonewtons of afterburning thrust. GE’s F404 production line for the Tejas program had gone largely dormant after an earlier 65-engine batch was completed around 2016, and restarting it — while working through a supply chain that includes at least one critical South Korean component supplier — has been the primary driver of the delays, according to Indian and regional defense trade press.
HAL signed the initial ₹5,375 crore (about $716 million) contract for 99 F404-IN20 engines in January 2021 to support an order of 83 Tejas Mk1A jets. A follow-on agreement for 113 more engines, worth roughly $1 billion, was signed on November 7, 2025, tied to an expanded order covering 97 additional aircraft — bringing the total planned Tejas Mk1A fleet to 180 jets and the combined engine order to 212 units, according to HAL and India’s Ministry of Defence. Deliveries under the newer contract are scheduled to run from 2027 through 2032.
Who Uses It
Confirmed operator: The Indian Air Force is the sole confirmed customer for the Tejas Mk1A and its F404-IN20 engines, with the type intended to backfill retiring Soviet-era and Anglo-French fighter squadrons. Earlier Tejas Mk1 variants, also GE-powered, are already in IAF service. No export customer for the Mk1A has been confirmed; Tejas variants have been offered to prospective buyers including Argentina, the Philippines and Egypt in past marketing efforts, but none of those discussions has converted to a signed order as of this writing.
Export/Procurement History
- 2021 (pre-2016 batch): An earlier order for 65 F404 engines for prior Tejas variants was completed, after which GE’s dedicated production line went largely idle.
- January 2021: HAL and GE Aerospace sign a ₹5,375 crore ($716 million) contract for 99 F404-IN20 engines tied to an 83-jet Tejas Mk1A order.
- 2025 and earlier: Deliveries slip repeatedly; by December 2025 only five engines had reached HAL, with a sixth delivered by April 2026.
- April 2, 2026: HAL confirms it is applying liquidated-damages penalties against GE for the delays.
- April 13, 2026: GE Aerospace and the Indian Air Force sign a separate contract to build an in-country F404-IN20 maintenance depot.
- July 8, 2026: GE hands over the seventh engine under the original contract.
- August 2026: GE delivers a batch of three additional engines, bringing the cumulative total to roughly ten of 99 ordered.
- November 7, 2025: HAL and GE sign a follow-on contract for 113 more F404-IN20 engines, worth about $1 billion, tied to 97 additional Tejas Mk1A aircraft, with deliveries running 2027–2032.
Global Competitors
The Tejas Mk1A competes for export interest in the same single-engine light-fighter segment as Pakistan and China’s jointly developed JF-17 Thunder Block III — which itself relies on a Chinese-built engine to sidestep the kind of Western supply dependency now constraining HAL — and, at a heavier and pricier tier, Saab’s Gripen E/F. India’s own reliance on a single foreign engine supplier for its flagship indigenous fighter has repeatedly been cited by Indian defense commentators as the central vulnerability the Tejas program has yet to design around; the same dependency is under scrutiny for India’s future twin-engine AMCA stealth fighter, which is also expected to fly initially on GE turbofans before a planned shift toward a jointly developed engine.
Why It Matters
The engine bottleneck strikes at the credibility of India’s “Atmanirbhar Bharat” (self-reliant India) defense-manufacturing push, since a program marketed as indigenous remains dependent on a single American supplier for its most critical, highest-value component — a contrast to New Delhi’s parallel push to move DRDO missile technology into private Indian hands. It also has direct operational consequences: the Indian Air Force’s sanctioned squadron strength has been sliding well below its 42-squadron target as MiG-21s and other legacy types retire faster than the Tejas Mk1A can be inducted, a gap regional analysts frequently weigh against China’s and Pakistan’s fighter modernization. For GE Aerospace, sustained delivery failures on a marquee export contract carry reputational risk just as Washington and New Delhi have been promoting deeper defense-industrial cooperation, including potential GE engine technology transfer for the AMCA program.
What Happens Next
The near-term test is whether GE can hold its stated pace of 24 to 26 engines a year; industry observers cited in Indian trade coverage suggest that if the accelerated schedule holds, HAL could begin handing completed Tejas Mk1A jets to the Indian Air Force before the end of 2026, working through the backlog of airframes already built and waiting on the line. Delivery of the follow-on 113-engine order is not due to begin until 2027, meaning the current batch of shipments remains the near-term bottleneck for closing the IAF’s squadron gap. The in-country depot agreement signed in April 2026 should, once operational, reduce how long individual engines are out of service for overhaul — a secondary factor in fleet availability once aircraft start reaching squadrons in volume. The episode is likely to feed into other governance debates around India’s state-run defense primes, alongside the ongoing board-level dispute at BrahMos Aerospace, as New Delhi weighs how much control to keep in-house versus hand to private industry.
FAQ
Why is the Tejas Mk1A delayed?
The airframes themselves are largely ready; the bottleneck is GE Aerospace’s F404-IN20 engine, whose dedicated production line sat mostly idle for years before India’s 2021 order and has been slow to ramp back up amid global supply-chain constraints, including a critical South Korean component supplier.
How many F404 engines has GE actually delivered to HAL?
As of the most recent shipment in August 2026, HAL had received roughly ten of the 99 engines ordered under the 2021 contract, after a batch of three arrived that month following a seventh-engine handover in July.
Has HAL fined GE Aerospace over the delays?
Yes. HAL’s then-chairman Dr. D.K. Sunil confirmed in April 2026 that liquidated-damages penalties provided for in the contract were being applied against GE for missed delivery deadlines.
Does the Tejas Mk1A have any confirmed export customers?
No. The Indian Air Force is the only confirmed operator of the Tejas Mk1A. India has marketed the aircraft to several prospective buyers, but no export contract has been signed as of this writing.
What is India doing to reduce its dependence on GE for fighter engines?
India and the United States have discussed technology transfer for future fighter engines, including for the twin-engine AMCA stealth fighter program, but the Tejas Mk1A itself remains contractually tied to GE’s F404-IN20 through at least the current and follow-on orders running to 2032.
