A major fire broke out at an under-construction warship of the Navy at Mazgaon Dockyard here on Friday evening and one person died after being trapped inside, a senior city fire brigade official said.

"Under-construction warship 'Visakhapatnam' caught fire at 5.44 pm. The blaze erupted on the second deck of the ship," said PS Rahangdale, the chief of the city fire brigade.

Eight fire-fighting engines, along with quick-response vehicle, have been pressed into service to extinguish the blaze, he said.
"Fire is confined to the second and third deck of the warship. Fire-fighting operation is underway along with Dockyard fire-fighters. The smoke has spread in the warship. We suspect that one person is trapped inside," Rahangdale said.
"The cause of the fire will be ascertained after a proper inquiry, but the first priority is to douse the fire with a minimum loss," another fire brigade official said.

Mazgaon Dockyard is the only facility in India having the capability to build submarines. Visakhapatnam, the largest warship of its class, was unveiled for construction in Mazgaon Docks in April 2015.

It is the first of the four stealth guided missile destroyers to be built under Project 15-B Class.
