The Visakhapatnam class (Project 15B) is a class of stealth guided missile destroyers currently being built for the Indian Navy. Based on the Kolkata-class design, the Visakhapatnam class will be an extensively improved version. Ordered in 2011, the first ship is expected to be completed in 2018. Project 15B destroyers will feature enhanced stealth characteristics as well as incorporate state of the art weaponry and sensors including the long range Barak 8 surface-to-air missile. The keel of the first P-15B ship was laid in October 2013.

In January 2011, the Cabinet Committee on Security gave approval for a follow-on order of four more destroyers under Project 15B. Project 15B will retain the same hull as 15A Kolkata-class destroyers, but there will be significant changes in the superstructure that will improve the ship's stealth characteristics, it will incorporate a flush deck, include better acoustic signature and infrared signature reduction systems and more sophisticated weaponry such as: Nirbhay land-attack cruise missiles, supersonic anti-ship BrahMos and Barak 8-ER SAMs. They will also be capable of operating two helicopters simultaneously. Russia's Baltic Shipyard has been contracted to provide four sets of line shafts by 2017. Saint Petersburg's Northern Design Bureau was consulted during the design phase.

The Indian Navy has reported the ships will have a displacement of 7,300 tons (or 7,400 tonnes), however, other sources have stated 8,000 tonnes.
