NEW DELHI: The Indian Navy is mulling the procurement and induction of five midget submarines into its force in a bid to bolster its underwater capabilities, Defence Ministry sources said on Sunday.

“The plans to procure the midget submarines, which weigh less than 150 tons, came in the aftermath of the Mumbai terror attacks last November, in which the militants used sea route to enter India.

The vessels will be inducted into the Marine Commandos force to carry out surveillance as well as attack operations,” the sources said.

The Indian Navy currently maintains a fleet of diesel-electric submarines.
