History[edit | edit source]
Background[edit | edit source]
On 23 December 2013, the Defence Acquisition Council (DAC) –- the main acquisition panel subordinate to India's Ministry of Defence (MoD), approved the procurement of sixteen anti-submarine warfare (ASW) vessels capable of operating in shallow waters, at a cost of ₹13,440 crore (equivalent to ₹180 billion or US$2.6 billion in 2019), to replace the ageing Abhay-class corvettes of the Indian Navy – which were commissioned between 1989 and 1991. This includes the development of the vessels with about 700 t (690 long tons; 770 short tons) displacement and an operational radius of 200 nmi (370 km; 230 mi) from its home port. They would be built by Garden Reach Shipbuilders and Engineers (GRSE).[1][2]
In June 2014, the MoD issued a tender, worth USD2.25 billion under the 'Buy and Make India' category to private-shipyards – including Larsen & Toubro (L&T), ABG Shipyard, Pipavav Defense and Offshore Engineering, Goa Shipyard (GSL) and Garden Reach Shipbuilders & Engineers (GRSE), for the procurement of the 16 anti-submarine vessels.[3]
In October 2017, Cochin Shipyard (CSL) and Garden Reach Shipbuilders & Engineers (GRSE) emerged as the first and the second-lowest bidder in the tender, respectively. CSL had quoted a value of ₹5,400 crore (US$829.22 million) while GRSE had to match the bid value of CSL in order to get the contract.[4]
Purchase[edit | edit source]
On 29 April 2019, the MoD and GRSE signed a contract, valued at ₹6,311.32 crore (US$880 million), for eight anti-submarine vessels, to be delivered between 2022 and 2026. The contract mandates the first vessel to be delivered within 42 months of the date of signing, with the remaining seven vessels delivered at a rate of two ships per year within 84 months.[5][6]
On 30 April 2019, the MoD and CSL signed a similar contract for the construction of the remaining eight vessels – within a deadline of 84 months.[7] Under this contract, the first ship was also expected to be delivered within a span of 42 months, with subsequent deliveries of two ships per year.[6][8][9]
Construction[edit | edit source]
The keel laying ceremony of the Mangrol (BY 524) was conducted on 21 February 2023.[10] The first three ships of the class, christened as Mahe, Malwan and Mangrol were launched simultaneously launched on 30 November 2023.[11][12]
Namesake[edit | edit source]
The ship, Mangrol, was named after the former minesweeper that was in service with the Indian Navy between 1983 and 2004. The minesweepers and these vessels inherit their name from multiple ports.
