Kolkata-class destroyer
2006 class of Indian guided missile destroyers
The Kolkata-class destroyers, also known Project 15A or Project 15 Alpha, is a class of three VLS-equipped 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.
Design
The Kolkata class share similar dimensions to the previous Delhi class, however they have 2,363 modifications which include major upgrades in weaponry, sensors and helicopter systems. With a standard displacement of 6,800 t (6,700 long tons; 7,500 short tons) and a full-load displacement of 7,400 t (7,300 long tons; 8,200 short tons), they are the largest destroyers ever operated by the Indian Navy. Some media reports have even given a full-load displacement of 7,500 t (7,400 long tons; 8,300 short tons). These are the first stealth destroyers built by India and marked a significant development in India's shipbuilding technology. The ships incorporate modern weapons and sensors, and have an advanced information warfare suite, an auxiliary control system with a sophisticated power distribution architecture, and modular crew quarters.
The class have a length of 163 m (534 ft 9 in), a beam of 17.4 m (57 ft 1 in) and a draught of 6.5 m (21 ft 4 in).
This brief starts where responsible research should: with the source description of “Kolkata-class destroyer” as 2006 class of Indian guided missile destroyers. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as 2006 class of Indian guided missile destroyers. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 5, 2026. The linked authority identifier is Q135703. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2010 and 2014.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
