Garden Reach Shipbuilders & Engineers Limited (GRSE) is a Kolkata-based shipyard on the eastern bank of the Hooghly River and one of India's principal builders of warships for the Indian Navy and Coast Guard. A Mini-Ratna Defence Public Sector Undertaking under the Ministry of Defence, GRSE has one of the longest shipbuilding pedigrees in the country, tracing its origins to the late nineteenth century, and specialises in frigates, corvettes, survey vessels and smaller patrol and anti-submarine craft, alongside a growing export order book.

History

GRSE began in 1884 as a small privately owned engineering and shipbuilding concern on the Hooghly River, and was renamed Garden Reach Workshop in 1916 as it expanded its shipbuilding and repair activities. The Government of India nationalised the company in 1960, after which it developed into a dedicated naval shipyard, building its first warship for the Indian Navy soon afterwards and steadily expanding its capability from patrol craft to increasingly complex frigates and corvettes over the following decades.

Warships built

GRSE has designed and built well over a hundred warships and patrol vessels for the Navy and Coast Guard, spanning guided-missile frigates such as the Godavari- and Brahmaputra-class ships, Kamorta-class anti-submarine corvettes, Sandhayak-class survey vessels, fleet tankers, landing ships and fast patrol craft and hovercraft. It is also one of two yards, alongside Mazagon Dock, constructing the Nilgiri-class (Project 17A) stealth frigates, and it builds the Arnala-class anti-submarine warfare shallow water craft for coastal and littoral operations. In March 2026 GRSE delivered three warships to the Navy in a single day for the first time, comprising the survey vessel INS Sanshodhak, the Nilgiri-class frigate INS Dunagiri and the Arnala-class vessel INS Agray, underlining the yard's expanded simultaneous-build capacity.

Exports and current programme

Alongside naval construction, GRSE has built a track record in defence exports, delivering the corvette Barracuda to Mauritius in 2014 and further vessels to Seychelles, and it is currently building patrol boats for the Bangladesh government under an export contract. Its present order book includes additional Project 17A frigates, further large survey vessels, a series of anti-submarine warfare shallow water craft and next-generation offshore patrol vessels, alongside commercial shipbuilding and engineering work.

Recent developments

GRSE's steadily improving order book, delivery record and profitability led the Ministry of Defence to recommend the yard for an upgrade from Mini-Ratna to Navratna status, a proposal cleared by an inter-ministerial committee in early 2026. The change would give GRSE greater financial and operational autonomy to pursue investment, joint ventures and export opportunities, reflecting its transformation from a modest nineteenth-century workshop into one of India's most productive warship-building yards.
