Serial production of India’s indigenously developed Tejas Mk-1A Light Combat Aircraft (LCA) could face further delays as the Indian Air Force (IAF) demands the incorporation of new and upgraded systems.

Sources from within manufacturer Hindustan Aeronautics Limited (HAL) told Jane’s on 22 May that the IAF recently informed the state-owned aerospace company that the Mk-1A model needs to feature advanced ‘smart cockpit’ multi-function displays and identification friend-or-foe (IFF) systems.

Moreover, the service demands that digital map generators and upgraded radio altimeters be fitted onto the aircraft before it is approved for serial production.

Industry sources said that although some of these systems can be commercially sourced, integrating them with the software currently installed on the fighter’s mission computer would be “time-consuming” and could defer the fighter’s production schedule by about two years.
