All the above destroyers are being built by Mazagon Dockyard Limited (MDL) in India.
The destroyers are an improved version of the Kolkata-class (Project 15A) and will feature enhanced stealth characteristics. The first ship is expected to enter service in 2021.
The ship was named after the Indian soldiers who fought during World War II in the Battle of Imphal and Kohima for 1944.
These ships were indigenously designed by the Directorate of the Indian Navy. Each vessel spans a length of 163 meters and displaces 7,300 tons. Four gas turbines will propel these ships to reach speeds exceeding 30 knots.
Why is INS Imphal Special:
