India's indigenous fighter aircraft program reaches a significant milestone as Hindustan Aeronautics Limited (HAL) prepares to deliver the first two LCA Mk1A jets by October 2025. Despite delays in engine deliveries from the US, HAL has maintained its pace to strengthen the Indian Air Force (IAF).
Understanding LCA Mk1A: The Importance of Indigenous Fighter Jets
The LCA (Light Combat Aircraft) Mk1A is a modernized version of the Tejas, a 4.5-generation multi-role fighter jet built with indigenous technology. It features an AESA radar, enhanced avionics, electronic warfare systems, and air-to-air refueling capability.
Tejas Mk1A will replace obsolete aircraft like the MiG-21, bolstering the IAF's squadron strength. In 2021, a deal for 83 aircraft, including 73 fighters and 10 trainers, was struck at ₹48,000 crores, increasing localization from 50% to 60%. These jets are capable of operating in high-threat environments, boasting a speed of Mach 1.8 and a range of 1500 km.

The Engine Delay Dilemma: Awaiting F404 from America
The main delay concerned the delivery of GE F404-IN20 engines from the US. HAL signed a deal for 99 engines at ₹5,375 crores with GE in 2021. The first engine arrived in April 2025, followed by the second in July, with supply chain issues causing further delays. Two more engines are expected this month, reaching a total of 12 by the year's end.
GE has committed to delivering 20 engines annually from 2026 onwards. Although initial deliveries were postponed from March 2024, HAL has adopted a backup plan using pre-owned engines. Already, 10 F414 engines (for the Mk2) have arrived.
Preparation for the First Delivery: Ten Aircraft Ready
According to HAL sources, ten aircraft have already been produced and tested. The first aircraft from the Nasik plant is ready for handover in October. HAL has launched a third production line in Nasik capable of manufacturing 24 jets annually, complementing two existing lines in Bengaluru. A total of 83 jets will be delivered by 2029, following a four-quarter delay. HAL's Chief DK Sunil stated that production is on a firm footing.

A Triumph in Weapon Integration Testing
The LCA Mk1A has successfully tested Astra and ASRAAM missiles, capable of engaging targets beyond visual range (BVR). The aircraft is equipped with the Uttam AESA radar, electronic warfare systems, and BVR missiles.
Additional Orders and Future Plans
An additional order worth ₹62,000 crores for 97 Mk1A units has been approved by the CCS. Cost negotiations are complete, with signing expected this month. A total of 180 aircraft will be delivered by 2031-32. Mk2 rollout by 2027, with its first flight in 2026. HAL is working on upgrading 15 Su-30MKI jets, while the ALH fleet inspection concludes this month.
The initial delivery of LCA Mk1A jets in October, despite engine delays, marks a victory for 'Atmanirbhar Bharat' (Self-Reliant India). HAL's expanding capabilities are set to significantly strengthen the IAF, though timely delivery remains crucial.
