Yeah, Smart-L does have BMD search capability. I believe a more powerful version in the pipeline.

BEL has the L band Rawl-03 and a S band Missile Defense Radar. One of these are going to be on our future ddg/frigates.

The Type 45 Sampson radar is a two faced radar, with reduced weight, which allowed them to create a tall mast. I thought our MF-Star mast was tall, Type 45 is really tall.

OT, the Air Marshal mentions that AWACS India is yet to receive CCS approval. This is bit strange as I thought funding was approved in 2015 and LRDE has already build the AESA antenna as disclosed by DRDO ex-chief.

May be he was referring to the two Phalcon, which is in the pipeline.
