Repeated delays in the supply of F404-IN20 engines from GE Aerospace, along with supply chain disruptions and certification hurdles, Hindustan Aeronautics Limited has confirmed that the Tejas Mk1A programme is running well behind its original timeline. The ₹48,000 crore contract, signed in 2021 for 73 single-seat fighters and 10 trainers, was originally scheduled to begin deliveries in early 2024. As of June 2026, not a single aircraft has been handed over to the Indian Air Force.
The primary reason for the delay lies with engine supplies. HAL has already invoked contractual liquidated damages on GE Aerospace for missing multiple delivery deadlines. While HAL has managed to complete around 18 airframes, several of these jets remain grounded as they await engines. A few aircraft are reported to be fully ready with major contracted capabilities, but the absence of powerplants has stalled final integration and delivery.
The Ministry of Defence is now reviewing the persistent delays and is considering imposing penalties on HAL. Senior officials, including Defence Minister Rajnath Singh, have held high-level meetings to assess the situation. The government is examining options such as liquidated damages to enforce accountability and push for faster execution. This move comes at a time when the Indian Air Force continues to operate with a reduced number of fighter squadrons.
The delays have occurred across multiple fronts. Apart from engine shortages, certification processes for the upgraded AESA radar, electronic warfare suite, and other systems have taken longer than expected. Supply chain issues, many linked to global disruptions, have further slowed production at HAL’s Bengaluru and Nashik facilities. HAL maintains that once engine supplies stabilise, it can deliver between 18 and 24 Tejas Mk1A jets by the end of 2026.
The Ministry’s intent is clear, it wants to avoid further slippage without consequences. While HAL has been asked to accelerate production, the government is also signalling that repeated delays will not be tolerated without financial penalties. Officials are monitoring progress closely, with the first deliveries now expected no earlier than August or October 2026, provided current bottlenecks are resolved.
The Tejas Mk1A was expected to help bridge the squadron strength gap and gradually replace older MiG-21s. Every month of delay keeps pressure on the existing fleet and slows down the force’s transition to newer platforms.
The coming months will be critical. HAL must demonstrate that it can overcome the engine and certification issues.
