The Indian Navy has launched the second Vishakhapatnam-class guided-missile destroyer of Project 15B at Mazagaon Dock Ship Builders Limited (MDL), in Mumbai, India.

Under Project 15B, the four destroyer ships are being indigenously designed by the Directorate of Naval Design, New Delhi, and built by MDL. The contract for this construction was awarded in 2011.

In the last six years, the shipyard has launched an indigenous aircraft carrier and delivered three frigates, three destroyers and two corvettes.

"This event is yet another moment of truth for the Indian Navy and India’s quest for self-reliance and indigenisation."

Chief of Naval Staff Admiral Sunil Lanba said: “This event is yet another moment of truth for the Indian Navy and India’s quest for self-reliance and indigenisation.

“The Indian Navy stands fully committed to the call of ‘Make in India’ and we are extremely proud of the fact that all of our warships and submarines on order today are being constructed within the country.”

Christened as Mormugao, the destroyer has a length of 163m and a beam measuring 17.4m, and displaces 7,300t.

The ship is propelled by four gas turbines in a combined gas and gas (COGAG) configuration, and can operate at a speed of more than 30k.

The P15B destroyer is designed for improved survivability, sea keeping, and ship manoeuvrability. They are equipped to carry and operate two multi-role helicopters with a rail-less helo traversing system to support helicopter handling on-board.

Fitted with weapons and sensors, such as vertically launched missile system for long distance engagement of shore, sea-based and air targets, the ship will be difficult to detect due the specific shaping of its hull and use of radar transparent deck fittings.

The destroyer's network system includes integrated platform management system (IPMS), ship data network (SDN), automatic power management system (APMS) and combat management system (CMS).
