In May 2000, the government approved construction of three units of the Project 15A Kolkata Class destroyer. These vessels are a follow-on to the Type 15 Delhi Class destroyer and construction is expected to begin at Mazagon Dockyard Ltd. in 2005. The P15A destroyer will possess enhanced stealth features and land-attack capabilities and is expected to add a new dimension in naval warfare for the Indian Navy, along with the Talwar {Krivak III} Class destroyer and the 'new' Nilgiri {Project 17} Class frigate. Construction of the first P15A destroyer commenced with plate cutting on 12 March 2003, with the keel being laid in September 2003 and the vessel (to be named Kolkata) was launched on 30 March 2006 at Mazagon Dock, Mumbai. She was launched by Mrs Roopa Byce, wife of Vice Admiral Sangram Singh Byce, Flag Officer Commanding in Chief - Western Naval Command. This lead ship is expected to commission sometime in 2010, with her sister ships following in 2011 and 2012 respectively.

A news article in The Hindu stated that the Kolkota Class will be armed with 16 BrahMos launchers. This was confirmed by Dr A S Pillai, CEO & MD of BrahMos Aerospace, who stated that the Kolkata will be armed with 16 vertically-launched BrahMos missiles. A new long-range, surface-to-air missile is currently being developed by DRDO (Defence Research & Development Organisation) as the lead SAM aboard these vessels and this missile will likely be the follow-on variant to the Barak SAM. The SAM load is expected to be double that of the Delhi Class and as many as 48 such missiles are planned to be carried on-board. The sonar fit is reported to be the HUMSA-NG hull mounted sonar and the NAGIN active towed array sonar, both manufactured by Bharat Electronics Limited (BEL).

Rear Admiral SKK Krishnan (Retd.) - Mazagon Dock's Chief Managing Director - said at the launch of the first vessel, "Project 15A, although conceived as a follow-on of the earlier Delhi Class, will have major advances in its weapons & sensors and will be technologically far more superior." He further added, "Jointly with the Director General of Naval Design, we have made many changes in the design of the ship. Most importantly we are building this series in a fixed price contract." The RIA Novosti news agency reported on 27 August 2007, that the Baltisky Zavod Shipyard was awarded a $20 million contract by the Indian Navy to build three sets of shaft lines for the three Project 15A Class destroyers. Each set includes a pair of shaft lines and a pair of propellers. The first shipment is planned for 2008, the second in 2009 and the third in 2010. The vessels have a length of 163 metres, a width of 17.4 meters and a displacement of 6,800 tons and will carry two helicopters on board. The ship will be propelled by four gas turbines, which is designed to achieve speed in excess of 30 knots.

The PJ-10 (BrahMos) is the naval variant of a cruise missile, that completed development by a joint team of scientists at India's DRDO (Defence Research & Development Organisation) and Russia's NPO Mashinostroyeniya. Technology has been derived from the Russian Yakhont ASCM and has provided vital inputs in designing the missile. BrahMos has been derived from the names of rivers, Brahmaputra and Moskva (from which Moscow derives its name), and illustrates the joint Indian-Russian development of the missile. Serial production of the missile has begun and the Rajput Class destroyers are among the first surface combatants to receive the missile.
