History

Background

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 ₹230 billionorUS$2.7 billion in 2023), 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). [11] [12]

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. [13]

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. [14]

Purchase

On 29 April 2019, the MoD and GRSE signed a contract, valued at ₹6,311.32 crore (equivalent to ₹78 billionorUS$930 million in 2023), 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. [15] [16]

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. [17] 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. [16] [18] [19]

Construction

The steel cuttting of the first ship of the class was completed by 1 December 2020 at BY 523 of the shipyard. [20] The keel laying ceremony of the ship was conducted on 30 August 2022. [21] The first three ships of the class, christened as Mahe, Malwan and Mangrol were launched simultaneously launched on 30 November 2025. The delivery of the first ship was then scheduled in 2024. [22] [23]

The ship was delivered to the Indian Navy on 23 October 2025. Commander Amit Chandra Choubey is the Commanding Officer (Designate) of the ship. [3] [24] [25]

The ship is expected to be commissioned in the month of November 2025. [26]

Namesake

The ship, Mahe, was named after the former minesweeper that was in service with the Indian Navy between 1983–2006. The minesweepers and these vessels inherit their name from multiple ports, in this case Mahé, of India to represent the strategic importance held by these establishments. [22] [3]

Design

The basic design of the ship has been sourced from Kochi-based Smart Engineering & Design Solutions followed by detailed design by the shipyard. Additionally, Finland-based Surma provided the signature management software and design inputs for combat survivability features. [20] The ships are being constructed as per the classification rules of Det Norske Veritas (DNV). [24] [25] The ship has an indigenous content of over 80%. [3]
