Tech Desk: Hindustan Aeronautics Limited (HAL) is at a pivotal juncture with its HLFT-42 project, prioritizing engine selection to finalize the design by 2030. This supersonic, dual-role jet is poised to become a critical link between basic and advanced combat training for the Indian Air Force (IAF), ultimately replacing its aging BAE Hawk 132 fleet. First unveiled at Aero India 2023, the HLFT-42 is envisioned as both a modern Lead-in Fighter Trainer (LIFT) and a capable light combat aircraft.

Designed to train pilots for next-generation aircraft like the Tejas Mk2 and AMCA, the HLFT-42 boasts a Maximum Take-Off Weight of 16.5 tonnes and a top speed of Mach 1.8. It will feature cutting-edge systems, including AESA radar, IRST, and an EW suite, alongside a significant payload capacity of 4.5 tons across 11 hardpoints. This versatility allows it to carry advanced weapons, functioning as a cost-effective fighter or even a command center for loyal wingman drones.

HAL has explored engines like the Russian AL-31F and American GE F414. Current indications point towards an F414-class engine (98 kN thrust), aligning with a March 2025 RFI. A successful Transfer of Technology (ToT) deal for the GE F414 would significantly boost India’s manufacturing and offer logistical synergy by sharing commonality with the Tejas Mk2, reducing operational costs.

While leaning towards the F414, HAL keeps options open for a more robust 120 kN-class engine developed with Safran for the AMCA. The final decision hinges on IAF’s operational needs—a dedicated trainer versus a versatile fighter. HAL’s proactive internal funding of ₹1,000 crore reinforces India’s self-reliance push, ensuring steady progress for this ambitious program, which also sees interest from the Indian Navy for a naval variant.
