What Happened
- GE Aerospace has signed a contract with the Indian Air Force to help establish an engine maintenance facility within India for the F404-IN20 engines that power the Tejas fleet
- The facility will be owned and operated by the IAF, with GE providing technical support, personnel training, supply of spares, and specialised tooling — reducing India's dependence on overseas repair centres
- The move is expected to significantly improve turnaround times for engine overhaul — currently, engines requiring depot-level maintenance need to be shipped abroad, keeping aircraft grounded for extended periods
- The announcement marks a major step in the indigenisation of Tejas sustainment infrastructure, complementing the HAL production ramp-up of Mk1A aircraft
- GE has committed to accelerating engine deliveries: 20 F404 engines to be supplied by December 2026 as part of ongoing delivery obligations

Defence Platform Sustainment: The MRO Gap in India
Acquiring advanced military platforms is only the first step — sustaining their operational availability over decades requires a robust, responsive MRO ecosystem. India's defence MRO market covers aircraft, engines, helicopters, naval vessels, land systems, and electronics. For combat aircraft, engine MRO is the most complex and time-sensitive element because fighter engines operate at extreme temperatures and stress, requiring deep overhaul (replacement of hot section components, compressor blades, turbine discs) at regular intervals determined by flight hours and engine cycles. Without domestic depot capability, each overhaul event means shipping the engine abroad, loss of the aircraft from the fleet for weeks or months, and dependence on OEM scheduling and pricing.
- Fighter engine time between overhauls (TBO) typically ranges from 1,000 to 2,500 flight hours depending on engine type and operating conditions
- Depot-level MRO requires OEM-licensed technical data packages, specialised test cells to run engines at full power post-overhaul, and precision tooling
- IAF currently operates approximately 30 active fighter squadrons; improving serviceability by even 5–10% through faster MRO translates to meaningful additional sortie capacity without new aircraft procurement
- India's civil aviation MRO market is also growing, driven by IndiGo, Air India, and other carriers investing in domestic maintenance capabilities to reduce overseas MRO spending
Connection to this news: The GE Aerospace facility directly plugs the depot-level MRO gap for the F404-IN20 engine — the most critical single-point dependency in the Tejas Mk1A fleet's operational lifecycle.
HAL's Role in the Tejas Ecosystem: Production and Industrial Base
Hindustan Aeronautics Limited (HAL) is India's state-owned aerospace and defence company responsible for the manufacture, repair, and overhaul of military aircraft, helicopters, engines, and avionics. HAL is the designated production agency for the LCA Tejas and is building up its Nasik and Bangalore facilities to produce Tejas Mk1A aircraft at an increasing rate. The broader Tejas industrial ecosystem includes DRDO's ADA (design authority), HAL (manufacture and final assembly), and a network of approximately 100 Indian suppliers for airframe, avionics, and systems components.
- HAL's Tejas Mk1A production target: 16 aircraft per year at full production tempo (vs. 8 per year currently)
- HAL received its 5th F404-IN20 engine from GE in December 2025; engine supply has been the primary bottleneck slowing Mk1A deliveries to the IAF
- HAL's annual revenue exceeds ₹28,000 crore; the Tejas programme is among its largest ongoing contracts
- HAL also manufactures Su-30MKI engines (Kaveri-related work), helicopters (LCH Prachand, ALH Dhruv), and overhauls legacy fighters including Jaguar and Mirage-2000
Connection to this news: The in-country engine depot complements HAL's production scale-up — as more Mk1A aircraft enter service, the volume of engines requiring depot maintenance will grow proportionally, making the indigenous facility not just a strategic choice but an operational necessity.
Technology Transfer and Aerospace Skill Development
One of the critical clauses in India's defence procurement policy is the requirement for technology transfer (ToT) or offsets, which mandate foreign vendors to invest a portion of their contract value in India's defence industrial base. The GE Aerospace arrangement — where GE trains IAF technicians, provides technical data, and deploys support staff — is a form of technology transfer that builds indigenous human capital. The aerospace MRO sector is skill-intensive: technicians require multi-year training and OEM certification to be qualified to work on fighter engine components.
- Defence offset policy (under DAP 2020) mandates 30% offset obligations for foreign defence purchases exceeding ₹2,000 crore
- Offsets can be discharged through: technology transfer, FDI in Indian defence firms, direct purchase of Indian defence products, or establishment of maintenance facilities
- The IAF-GE depot creates a cadre of IAF personnel trained to OEM standards for F404 engine maintenance — a human capital asset that will outlast the current fleet generation
- India's aerospace sector needs an estimated 30,000–40,000 additional trained MRO technicians over the next decade as the civil and military aviation fleet expands
Connection to this news: The GE Aerospace facility establishes a training and technology transfer pipeline that positions India to progressively absorb more of the F404 maintenance workload, consistent with the Atmanirbhar Bharat trajectory.
Defence Acquisition Council (DAC) and Procurement Oversight
The Defence Acquisition Council (DAC) is the apex decision-making body for defence procurement, chaired by the Defence Minister. It provides in-principle approval (Acceptance of Necessity or AoN) for capital procurement proposals before they enter the detailed tender and contracting process. For the Tejas programme, the DAC has approved successive phases including the 83-aircraft Mk1A order, the additional 97-aircraft proposal, and associated support systems. MRO contracts of this scale typically require DAC clearance or at minimum Ministry of Defence approval at the appropriate financial delegated authority level.
- DAC composition: Defence Minister (Chair), Chiefs of all three Services, Chief of Defence Staff (CDS), Defence Secretary, Secretary (Defence Production), Scientific Adviser to Defence Minister
- DAC introduced the concept of "Categorisation" of procurement: IDDM (Indian Design, Development and Manufacture) enjoys highest preference; Buy (Global-MII) is the category relevant for the GE MRO arrangement
- The Long-Term Integrated Perspective Plan (LTIPP) guides 15-year capital acquisition planning for the armed forces; MRO sustainability is increasingly factored into whole-life cost assessments of platforms
- Services Capital Acquisition Plan (SCAP) is the 5-year rolling procurement roadmap derived from LTIPP
Connection to this news: The GE-IAF MRO contract would have navigated the DAC/MoD approval pathway — its conclusion signals formal government endorsement of the in-country depot model for the Tejas programme.
