The Kamorta-class corvettes or Project 28 are a class of anti-submarine warfare corvettes currently in service with the Indian Navy. Built at Garden Reach Shipbuilders & Engineers (GRSE), Kolkata, they are the first anti-submarine warfare stealth corvettes to be built in India.Project 28 was approved in 2003, with construction of the lead ship, INS Kamorta commencing on 12 August 2005. Two of the four corvettes, INS Kamorta and INS Kadmatt were commissioned in 2014 and 2016 respectively. The remaining two, INS Kiltan and INS Kavaratti are under construction and slated to be completed by 2017.

The platform and major internal systems of this class of corvettes are indigenously designed and built. The corvettes are named after the islands in the Lakshadweep archipelago.

The Kamorta class corvettes are intended to succeed the Kora-class corvette by precedence and Abhay-class corvette by role.

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 Garden Reach Ship Builders and Engineers, Kolkata. The ship was launched in the year 2010 and was inducted into the navy in 2014 after a series of delays. Construction of the second ship in the row, INS Kadmatt 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 are expected to be completed by the end of 2017.

Project 28'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.
