GE Enhances Tejas MK-1A with Prompt Engine Delivery Triumph
In a significant development for India’s defense sector, US-based aerospace giant General Electric (GE) has begun delivering the much-anticipated F-404 engines for the Tejas MK-1A Light Combat Aircraft (LCA). This milestone, announced in late March 2025, marks a turning point after a two-year delay that had raised concerns in both India and the United States.
The first batch of these engines is expected to reach Hindustan Aeronautics Limited (HAL) by the end of March, paving the way for the Indian Air Force (IAF) to bolster its fighter jet fleet.
The Tejas MK-1A, an advanced variant of India’s indigenous LCA, represents a cornerstone of the country’s push for self-reliance in defense manufacturing. Designed as a 4.5-generation, multi-role fighter jet, it is equipped with modern avionics, radar, and weaponry to meet the IAF’s growing needs.
However, production delays—primarily due to engine supply issues—had slowed progress, leaving the IAF awaiting the delivery of 83 jets ordered in a $6.5 billion deal signed in 2021. With GE now resuming deliveries, HAL aims to roll out the first Tejas MK-1A aircraft by mid-2025, offering a significant boost to India’s aerial defense capabilities.
A Long-Awaited Breakthrough
The delivery of the F-404 engines comes after prolonged supply chain disruptions that affected GE’s production timeline, originally set for March 2023. These setbacks frustrated Indian defense officials, who imposed financial penalties on GE Aerospace for failing to meet deadlines.
According to reports, the US firm has committed to supplying 12 engines in 2025, followed by 20 annually thereafter, fulfilling a $716 million contract for 99 engines. This steady supply is expected to help HAL meet its target of delivering 11 Tejas MK-1A jets by the end of 2025, with full completion of the 83-jet order anticipated within three years.
For the IAF, this development is critical as it grapples with a dwindling number of fighter squadrons—currently at 31 against a sanctioned strength of 42. The Tejas MK-1A is seen as a vital replacement for aging MiG-21 aircraft, which have been in service for decades. With the engines now arriving, HAL Chairman D.K. Sunil expressed optimism, stating that production is back on track and the company is prepared to accelerate output once the supply stabilizes.
Strengthening US-India Defense Ties
The resumption of engine deliveries also underscores the deepening defense partnership between the United States and India. Amidst global supply chain challenges and geopolitical tensions, this collaboration highlights a shared commitment to enhancing India’s military capabilities.
The US State Department has emphasized the strategic importance of this deal, noting that it reinforces bilateral ties at a time when India seeks to counter regional threats, particularly from China.
Moreover, discussions are underway for a potential technology transfer deal involving the more advanced GE F-414 engines, which could power future Tejas variants and India’s fifth-generation Advanced Medium Combat Aircraft (AMCA).
If successful, this agreement could see HAL manufacturing up to 80% of these engines domestically, further advancing India’s “Make in India” initiative and reducing reliance on foreign suppliers.
Overcoming Challenges
The road to this achievement has not been without hurdles. HAL faced criticism from IAF Chief Air Chief Marshal A.P. Singh, who, during the Aero India 2025 event in February, expressed frustration over the slow pace of Tejas MK-1A deliveries. Singh highlighted the urgency of modernizing the IAF’s fleet, urging HAL to adopt a more coordinated approach rather than working in silos.
In response, HAL has ramped up its production capacity, now capable of building 24 aircraft annually, with plans to scale up to 36 if needed.
To address earlier delays, HAL resorted to using reserve “Category B” engines for pre-delivery testing, ensuring that aircraft remained flight-ready until the new F-404s arrived. This contingency plan reflects the company’s determination to keep the project on course despite external setbacks. With the first engines now on the test bed and shipments underway, HAL is poised to regain the IAF’s confidence and meet its ambitious deadlines.
A Boost for India’s Aerospace Ambitions
The Tejas MK-1A’s enhanced features—including an Active Electronically Scanned Array (AESA) radar and improved electronic warfare systems—position it as a formidable asset in modern air combat. Capable of carrying air-to-air missiles like the indigenous Astra and precision-guided bombs, it offers versatility for both air superiority and ground strike missions.
As production ramps up, the aircraft is expected to become a workhorse for the IAF, filling critical gaps in combat airpower.
Beyond the immediate order, HAL’s order book is valued at $16 billion, with contracts for an additional 97 Tejas MK-1A jets and 156 Light Combat Helicopters in the pipeline. These deals, likely to be finalized by late 2025, signal India’s long-term commitment to indigenous defense manufacturing. The success of the Tejas program could also elevate India’s status as a global aerospace hub, attracting international interest and investment.
Looking Ahead
For audiences in the US and India, this milestone carries broad implications. In the US, it reinforces GE’s role as a key supplier in the global defense market, despite earlier logistical challenges.
For India, it marks a step toward technological independence and military readiness, aligning with national priorities under the “Atma Nirbhar Bharat” (Self-Reliant India) campaign. As HAL prepares to integrate the new engines and conduct pre-delivery flight tests with the IAF, the focus now shifts to execution and quality assurance.
While challenges remain—such as ensuring consistent engine supply and meeting certification requirements—the outlook is promising. The Tejas MK-1A program, coupled with advancements in engine technology, underscores a pivotal moment for India’s defense industry.
With continued collaboration between GE and HAL, this aircraft could soon take to the skies, strengthening India’s position in an increasingly complex security landscape.
