High power sea water activated batteries in compact size to fit into the 324 mm diameter shells, contra rotating DC propulsion motors are the contribution of this project. Sensor instrumentation packages, hybrid control and guidance motors are fabricated within the country which were denied under the Technology control regimes.
The torpedo is capable of operating at depths of few hundred meters and homes on to its prey by passive/active homing and explodes on impact to destroy/damage the target submarine. Torpedo, on entry into water, performs pre-programmed search patterns, detects the targets and homes on to the target.
