The platform and major internal systems of this class of corvettes are indigenously designed and built.<ref name="globalsecurity">{{cite news|last1=Pike|first1=John|title=Project 28 ASW Corvette|url=http://www.globalsecurity.org/military/world/india/p-28.htm|access-date=18 August 2016|work=globalsecurity.org|url-status=live|archive-url=https://web.archive.org/web/20160808075024/http://www.globalsecurity.org/military/world/india/p-28.htm|archive-date=8 August 2016}}</ref> The corvettes are named after the islands in the Lakshadweep archipelago. The ''Kamorta''-class corvettes are intended to succeed the {{sclass|Kora|corvette|4}} by precedence and the {{sclass|Abhay|corvette|4}} by role.

==Design and description== In 2003, under the code name Project 28, the Indian Navy placed an order for four anti-submarine warfare (ASW) corvettes. The corvette's design was originally planned to be based on the Russian corvette Project 2038.2, however the basic design was later provided by the Indian Navy's Directorate of Naval Design, followed by the detailed design by Garden Reach Ship Builders and Engineers (GRSE).<ref name="globalsecurity"/> The design includes many stealth ship features, including reductions in acoustic signature and vibration of the vessels.<ref>{{cite web|url=http://www.georgians.in/article_detail.asp?aid=307 |title=Anti-submarine corvette for Navy next year |first=Amarjeet |last=Malik |publisher=General Military School |work=Georgians News |access-date=27 September 2014 |archive-url=https://web.archive.org/web/20150224095042/http://www.georgians.in/article_detail.asp?aid=307 |archive-date=24 February 2015 |url-status=dead}}</ref>

The class incorporates some major features including but not limited to the X-shaped hull form to improve stealth, a raft-mounted propulsion system to reduce vibration, and an infrared signature suppression system.<ref name="jni-6jan16"/> It also includes networks such as the Total Atmospheric Control System (TACS), Integrated Platform Management System (IPMS), Integrated Bridge System (IBS), Battle Damage Control System (BDCS) and Personnel Locator System (PLS). The ships also include technology that enables them to fight in nuclear, biological and chemical warfare (NBC) scenarios. The Indian Navy claims that the indigenisation achieved in these ships is about 90%.<ref name="IN"/>

===General characteristics and propulsion=== The overall length of the ''Kamorta''-class corvettes is {{convert|109|m|ftin}}, and the beam spans {{convert|13.7|m|ftin|abbr=on}}. The ships displace about {{convert|2500|t|LT|lk=on}} at standard load and {{convert|3500|t|LT}} when fully loaded. Each ship retains a complement of 180 sailors and 13 officers.<ref name="jni-6jan16"/>

They are propelled by four Pielstick 12 PA6 STC diesel engines, each with a power of {{convert|5096|hp|lk=in}} in CODAD configuration. They also have two controllable pitch propellers which helps the ship achieve maximum speeds in excess of {{convert|25|kn|lk=in}}.<ref name="IN"/>

The fire-control system is the Bharat Electronics IAC Mod C system.<ref name="jni-6jan16"/>

There is an option to include surface-to-air missiles. As of 2022, Indian Navy is planning to integrate VL-SRSAM. The corvette can hold one helicopter, which currently is a Westland Sea King Mk.42B helicopter.<ref name="IN"/>

==Construction== The order for four ''Kamorta''-class corvettes were placed in 2003 by the Indian Navy. Construction of the lead ship, INS ''Kamorta'' began in the year 2005 and the keel was laid down in 2006 at GRSE, Kolkata. The ship was launched in the year 2010 and was inducted into the navy in 2014 after a series of delays.<ref name="globalsecurity"/> Construction of the second ship, {{INS|Kadmatt|P29|6}} followed and the keel was laid in 2007. The corvette was launched in 2011 and was inducted in the early 2016. {{INS|Kiltan}} was laid down in 2010 and launched in 2013. While the last ship of its class, {{INS|Kavaratti}} was laid down in 2012 and launched in 2015. Both the ships were commissioned in 2017 and 2020 respectively.<ref name="dnainida"/>

The project's objective was to enhance localization and development of warship construction industry in India. The navy asked the Indian industries to deliver equipment of higher sophistication levels than usual. This led to some unforeseen delays in the product delivery, and struggles perfecting the products.<ref name="bs-privsector">{{cite news |url=http://www.business-standard.com/india/news/warship-project-delayed-to-buildprivate-sector/365553/ |title=Warship project delayed to build up private sector |newspaper=Business Standard|last=Shukla |first=Ajai |date=1 August 2009 |access-date=27 September 2014 |url-status=live |archive-url=https://web.archive.org/web/20120331135840/http://www.business-standard.com/india/news/warship-project-delayed-to-buildprivate-sector/365553/ |archive-date=31 March 2012}}</ref><ref>{{Cite news|url=http://www.thehindubusinessline.com/economy/strict-adherence-to-indigenisation-norm-delays-production-of-antisub-warfare-ships/article10030638.ece|title=Strict adherence to indigenisation norm delays production of anti-sub warfare ships|last=Nair-Ghaswalla|first=Amrita|date=2018-01-12|work=The Hindu Business Line|access-date=2018-01-13|language=en|url-status=live|archive-url=https://web.archive.org/web/20180303201840/https://www.thehindubusinessline.com/economy/strict-adherence-to-indigenisation-norm-delays-production-of-antisub-warfare-ships/article10030638.ece|archive-date=3 March 2018}}</ref>

All the ships of this class are built using DMR 249A special grade high-tensile steel,<ref name="IN"/> produced by the state-owned Steel Authority of India Limited (SAIL), and carbon fiber reinforced plastic (CFRP) materials. The main machinery is raft mounted, and each gear unit and its associated engines are mounted on a common raft. The diesel engines are license built by Kirloskar under SEMT Pielstick of France. DCNS supplies the noise-suppressing raft-mounted gearbox for CODAD propulsion. Wärtsilä India manufactures the low-vibration diesel alternators to power the on-board electronics.<ref name="bs-privsector"/><ref>{{cite news|title=Bharat-Rakshak.com : Navy – Project 28 Class|url=http://www.bharat-rakshak.com/NAVY/ships/future/188-project-28.html|work=bharat-rakshak.com|archive-url=https://web.archive.org/web/20140222055851/http://www.bharat-rakshak.com/NAVY/Ships/Future/188-Project-28.html|archive-date=22 February 2014}}</ref>

INS ''Kiltan'' and INS ''Kavaratti'' are to be more advanced than their elder ships. In a first, composite materials, imported from Kockums, Sweden, are used for the construction of the superstructures. This resulted in increased stealth features, reduced weight relative to typical superstructures built with steel, anti-corrosive and fire resistant. It's also projected for the ships to have some additional armament and new features.<ref>{{cite news|title = GRSE's last two ASW corvettes to be very advanced: Navy |url = http://timesofindia.indiatimes.com/india/GRSEs-last-two-ASW-corvettes-to-be-very-advanced-Navy/articleshow/50288359.cms|website = The Times of India| date=22 December 2015 |access-date = 2016-01-01|url-status = live|archive-url = https://web.archive.org/web/20160112095042/http://timesofindia.indiatimes.com/india/GRSEs-last-two-ASW-corvettes-to-be-very-advanced-Navy/articleshow/50288359.cms|archive-date = 12 January 2016}}</ref><ref>{{cite news|title = INS Kavaratti launched |url = http://timesofindia.indiatimes.com/city/kolkata/INS-Kavaratti-launched/articleshow/47346159.cms|website = The Times of India| date=19 May 2015 |access-date = 2016-01-01|url-status = live|archive-url = https://web.archive.org/web/20160120071323/http://timesofindia.indiatimes.com/city/kolkata/INS-Kavaratti-launched/articleshow/47346159.cms|archive-date = 20 January 2016}}</ref><ref>{{cite news|title=Navy experimenting with composite superstructure for warships|url=https://economictimes.indiatimes.com/news/defence/navy-experimenting-with-composite-superstructure-for-warships/articleshow/47056945.cms|work=The Economic Times|agency=PTI|date=27 April 2015|access-date=1 January 2016|url-status=live|archive-url=https://web.archive.org/web/20160403011707/http://economictimes.indiatimes.com/news/defence/navy-experimenting-with-composite-superstructure-for-warships/articleshow/47056945.cms|archive-date=3 April 2016}}</ref>
