Tejas Mk1A testbed to receive ASRAAM Block-6 for testing and integration
The ASRAAM Block-6 comes with new algorithms that has been developed to improve its ability to acquire and maintain lock-on to the target aircraft despite the use of Next Generation infrared countermeasures by the target aircraft.
The European firm MBDA and Bharat Dynamics Ltd (BDL) have collaborated to establish an Indian facility for final assembly, integration and testing of the ASRAAM that will start operations later this year.
