Kolkata-class destroyer
The "Kolkata class" (Project 15A) are a class of stealth guided-missile destroyers constructed for the Indian Navy. The class comprises three ships – Kolkata, Kochi and Chennai, all of which were built by Mazagon Dock Limited (MDL) in India, and are the largest destroyers to be operated by the Indian Navy. Due to delays in construction and sea trials, the initial commissioning date of the first ship of the class was pushed back from 2010 to 2014.

The destroyers are a follow-on of the Project 15 Delhi-class destroyers, but are considerably more capable due to major improvements in the design, the addition of substantial land-attack capabilities, the fitting-out of modern sensors and weapons systems, and the expanded use of net-centric capability such as Cooperative Engagement Capability.
