INS Imphal (Pennant D68) is the third of four warships of Project 15B that together form the Visakhapatnam class stealth-guided missile destroyers.
This Visakhapatnam class has BrahMos surface-to-surface cruise missiles and vertically launched Barak-8 surface-to-air missiles for long-range engagement of shore and sea-based targets.
Between 2014 and 2016, the Indian Navy commissioned three guided missile destroyers of Kolkata class under a project codenamed ‘15A’.
The Kolkata class included INS Kolkata, INS Kochi and INS Chennai.
These ships were a step ahead of their precursor Delhi class of ships, which included INS Delhi, INS Mysore and INS Mumbai.
They built under Project 15 and commissioned between 1997 and 2001.
