Warships Nilgiri-class frigate (1972) The first warship built by MDL was the 2,900-ton displacement INS
Nilgiri, the lead ship of
her class. She was launched on 15 October 1966 and commissioned on 23 June 1972. Five more frigates of this class were built over the next nine years for the Indian Navy.
Godavari-class frigate While construction of the
Nilgiri class was being completed, the Indian Navy proposed requirements for an indigenously designed and built frigate. This new frigate was to be of wholly Indian design and manufacture. To address these requirements, MDL designed and built the
guided-missile frigates with a 3,800-tonne displacement and the ability to embark two helicopters. MDL built three ships of the class – the lead ship, , , and .
Khukri-class corvettes MDL designed and built the first two vessels of the s for the Indian Navy. The
lead vessel of the class was commissioned on 23 August 1989, and the second, , on 7 June 1990. The remainder of the class was built at
Garden Reach Shipbuilders and Engineers (GRSE) following a transfer of technology from MDL to diversify warship building capabilities to other yards, as well as to make room at MDL for larger projects.
Delhi-class destroyers The next class of vessels designed and built by MDL was Project 15
guided-missile destroyers. These were powered by
gas turbines and displaced 6,200 tonnes. The first of the class, , was launched in February 1991 and commissioned on 15 November 1997. The second, , was commissioned on 2 June 1999, followed by the last ship in the series, , on 22 January 2001.
Shivalik-class frigates The 6000-ton (Project 17) frigates are the first warships with stealth features to be designed and built in India. These multi-role, guided-missile frigates have reduced radar signatures and have entered service from 2010 onwards. At least three of this class have been constructed at MDL. The lead vessel of the class was commissioned on 29 April 2010. The last ship of the class, INS
Sahyadri, was launched on 27 May 2005 and commissioned on 21 July 2012.
Kolkata-class destroyers vessels are the next-generation of guided-missile destroyers in the 7,400-tonne range to be designed and built at MDL. They incorporate stealth features. The lead vessel of the class was launched on 30 March 2006. At least three vessels of the class were planned. All three are in active service.
Visakhapatnam-class destroyers vessels are the next-generation of guided-missile destroyers in the 7,500-tonne range to be designed and built at MDL. They incorporate stealth features and improved weapons and avionics compared to the Kolkata class. The lead vessel of the class was launched in 2018. At least four vessels of the class are planned.
Nilgiri-class frigates vessels are the next-generation of guided-missile frigates in the 6,500-tonne range to be designed and built at MDL and GRSE. They incorporate stealth features. The lead vessel of the class was launched on 28 September 2019. Seven vessels of the class were built by MDL and GRSE.
INS Mahendragiri, the seventh and final ship of the class was launched in Mumbai on 1 September 2023.
Coast Guard vessels The yard builds offshore
patrol vessels (OPVs) for the
Indian Coast Guard. These vessels are specialised ships built for patrolling, policing, and search and rescue operations in India's
exclusive economic zone. Each carries a helicopter on board. Seven such ships have been delivered.
Floating police stations Based on the order from the
Border Security Force (BSF), the yard started construction of floating border outposts (BOPs). Essentially these BOPs are floating police stations with four high-speed boats. The yard has delivered 9 out of an order of 14 BOPs.
Other vessels Among other ships, the yard has built three fast missile boats, a cadet training ship, and other utility ships for the Indian Navy. It has also built water tankers for the Iranian naval forces.
Submarines Shishumar-class submarine The s are a variant of the
Type 209 diesel-electric submarine designed by
Howaldtswerke-Deutsche Werft. Two vessels of this class were constructed at MDL, which are the first indigenously built submarines in India. was commissioned on 7 February 1992 and was commissioned on 28 May 1994.
Kalvari-class submarine MDL has built six diesel-electric submarines of the under a technology-transfer agreement with
Naval Group. , the first in this class, was commissioned on 14 December 2017 from
Naval Dockyard in Mumbai.
US Navy In September 2023, MDL became the second Indian shipyard after the
Kattupalli Shipyard of
Larsen & Toubro to sign a Master Ship Repair Agreement (MSRA) with the
US Government, represented by
NAVSUP Fleet Logistics Center (FLC)
Yokosuka, for
United States Navy's
Military Sealift Command Fleet Support Ships. The ships operated by MSC are non-commissioned US Navy “support vessels” with civilian crews bearing the prefix “
USNS”. Under the agreement, the US Naval ships of the
Central Command that are in voyage are to be repaired in India.
Upcoming projects P-75(I) submarine MDL's joint venture with
ThyssenKrupp, a German conglomerate, is the sole contender for the Indian Navy's
P-75(I) submarine program. Commercial negotiations with the Ministry of Defence began in January 2025. ==Commercial projects==
