The nucleus of Tejas Aircraft is Aeronautical Development Agency (ADA) whose principal partner is Hindustan Aeronautics Limited. Indian Air Force, Indian Navy, DGAQA, BEL, various DRDO and CSIR Laboratories, Private and Public Sector undertakings and several academic institutions have actively participated and contributed to this truly national venture which has directly and indirectly bridged major technological gaps in several disciplines. Today we have two Technology Demonstrators (TDs), Five Prototype Vehicles (PVs) which includes Two Twin Seater / Trainer, Seven Limited Series Production Vehicles (LSP) and two Naval prototypes undergoing Flight Trials.

The LCA Tejas Series Production-1 (SP1) was handed over by Defence Minister to Indian Air Force. Initial block of flight testing of Naval variant of LCA was successfully completed. A significant milestone of the maiden ski jump launch of the first LCA Navy Prototype was successfully carried out at Goa in Dec 2014. The progress of the Tejas is well marked by completion of Initial Operational Clearance (IOC) leading to the delivery of the first Series Production (SP1) aircraft to the IAF. The programme is triumphantly moving towards certification for Final Operational Clearance (FOC).
