#11 (Supersonic missile assited release of torpedo) was a pleasant surprise!! I had been wanting DRDO to take up this project/product for a while now!!!!
The concept/product is an old one that has existed with US Navy for about 50 years (known as ASROC). It is a no-brainer. Torpedos travel extremely sluggishly in water, as such it is best launched quickly in air as a rocket/missile and then a short-range torpedo (warhead of the rocket/missile) is released right over the submarine's location - with literally devastating effect.
