India's Tejas Mk1A Fighter Jet: A Step Toward Modernising the Air Force Amid Regional Challenges
India’s indigenous Tejas Mk1A fighter jet recently completed its maiden flight, marking a critical phase in modernising the Indian Air Force. With over 40 improvements from the previous model, the jet features advanced AESA radar, electronic warfare systems, and enhanced weaponry. HAL aims to deliver up to 12 jets to the IAF by the end of 2025, addressing capability gaps amid regional security threats.
The Tejas Mk1A, an upgraded variant of India's Light Combat Aircraft developed by Hindustan Aeronautics Limited (HAL), represents a significant enhancement in the nation’s indigenous air combat capability. It boasts key advancements including the Israel EL/M-2025 AESA radar and the indigenously developed Uttam AESA radar providing 360-degree target tracking beyond 200 km. The jet features an advanced digital fly-by-wire flight control system, an upgraded electronic warfare suite with radar warning and self-protection jammers, and carries a versatile payload including BVR missiles such as Astra and ASRAAM. The Mk1A also integrates improved communication systems and avionics for better situational awareness and combat effectiveness. India faces the challenge of replenishing its air force, which currently operates below its sanctioned strength, with plans to deliver the first batch of 12 Tejas Mk1A jets by the end of 2025 and complete deliveries of 83 aircraft by 2029. Despite past delays mainly due to supply chain constraints, particularly sourcing GE F404 engines, HAL’s ramped-up production aims to strengthen the Air Force’s fleet amid persistent regional threats. The Mk1A serves as a bridge until more advanced models like the Tejas Mk2 and Twin Engine Deck-Based Fighters become operational, underscoring India’s drive to bolster indigenous defense manufacturing and aerial prowess.
