The Indian Navy's sixth and final Kalvari class submarine, Vaghsheer, has begun its sea trials and is expected to be commissioned into the force by early next year.
The commissioning of the submarine, built under Project-75, is set to enhance the Navy's combat capability at a time when China has been increasing its presence in the Indian Ocean region.
"The sixth submarine of Project-75 commenced her sea trials on May 18," the Navy said.
