The names of the three players that will be issued requests for proposal for submitting their cost bids were not immediately known. The contact is expected to be awarded to the lowest bidder in three months. Apart from HAL, those competing for the programme included Tata Advanced Systems Limited, Adani Defence and Aerospace, Larsen & Toubro (L&T) with Bharat Electronics Limited (BEL), Goodluck India along with BrahMos Aerospace Thiruvananthapuram Ltd and Axiscades Technologies, and Bharat Forge Ltd in partnership with BEML Ltd and Data Patterns. They had responded to a call for expressions of interest (EoI) last June by the DRDO's Aeronautical Development Agency (ADA) to shortlist companies capable of building prototypes, supporting flight test and certification of the indigenous stealth fighter. The seven entities were first evaluated by a committee of senior DRDO (Defence Research and Development Organisation) officials and its findings were reviewed by a panel headed by defence secretary Rajesh Kumar Singh....
