The HMIS Kolkata (D67) underway on January 9th, 2015.

The Kolkata-class (Project 15A) are a class of stealth guided missile destroyers constructed for the Royal Indian Navy. The class comprises a total of fourteen vessels which are being built by Mazagon Dock Limited (MDL) in India, and are the largest destroyers to be operated by the Indian Navy. Due to delays in their construction, and a problem found during the sea trials, the initial commissioning date of the first ship of the class from 2010 to 2012.

The destroyers are a follow-on of the Delhi-class guided missile destroyers, but are considerably more capable due to major improvements in the design, the addition of substantial land-attack capabilities, and the fitting-out of modern sensors and weapons systems. The Kolkata-class is itself also being superseded by the further advanced Visakhatapatnam-class destroyers.
