The Indian Navy on Saturday will induct its indigenously built second Kalvari class diesel-electric submarine.
Defence Minister Rajnath Singh will commission the submarine which will be known as INS Khanderi.
Here are the glimpses of the submarine.
"It is a diesel-electric submarine which runs on battery, with a capability of firing six torpedoes. Its maximum speed is 20 nautical miles, which is a world standard for most of the attack type of submarines," the navy official said.
Another crucial feature of the new submarine is that unlike previous requirement of 60 crew, its maximum requirement is 36 crew. It saves oxygen availability and increases its capacity to stay under water for long periods, he said.
