DRDO’S Advanced Self Protection Jammer (ASPJ) undergoing flight testing

The Defence Research and Development Organziation (DRDO) is developing indigenous Advanced Self Protection Jammer (ASPJ) which will be equipped on Tejas LCA MK-1, MK-1A, MK-2 and Su- 30MKI fighter jets. As of now one (1) unit is undergoing Flight Testing; while another unit has been received for testing recently.

TEJAS ASPJ will use 16 element Active Transmit Receive Unit (ATRU) and MK-1 one will use 32 element ATRU. Noteworthy, this ASPJ is based on the advanced solid-state gallium arsenide (GaAs) based active electronically scanned array (AESA) unit technology or gallium nitride (GaN)-based solid-state active electronically scanned array (AESA) jammer transmitters.
