'''INS ''Mahe''''' is the [[lead ship]] of the ''Mahe'' class of the [[Anti-Submarine Warfare Shallow Water Craft|Anti-Submarine Warfare Shallow Watercraft]] operated by the [[Indian Navy]].

== History ==

=== Background ===
On 23 December 2013, the Defence Acquisition Council (DAC) –- the main acquisition panel subordinate to India's [[Ministry of Defence (India)|Ministry of Defence]] (MoD), approved the procurement of sixteen [[anti-submarine warfare]] (ASW) vessels capable of operating in shallow waters, at a cost of {{INRConvert|13440|c|lk=on|year=2013}}, to replace the ageing [[Abhay-class corvette|''Abhay''-class corvettes]] of the Indian Navy – which were commissioned between 1989 and 1991. This includes the development of the vessels with about {{Convert|700|t|abbr=on}} displacement and an operational radius of {{Convert|200|nmi|abbr=on}} from its [[home port]]. They would be built by [[Garden Reach Shipbuilders and Engineers]] (GRSE).<ref>{{Cite news |last=Bhatnagar |first=Gaurav Vivek |date=2013-12-24 |title=Four major acquisitions for the Navy and the Army approved |url=http://www.thehindu.com/news/national/four-major-acquisitions-for-the-navy-and-the-army-approved/article5494688.ece |url-status=live |archive-url=https://web.archive.org/web/20250915131130/https://www.thehindu.com/news/national/four-major-acquisitions-for-the-navy-and-the-army-approved/article5494688.ece |archive-date=2025-09-15 |access-date=2017-10-17 |work=The Hindu |language=en-IN |issn=0971-751X}}</ref><ref>{{Cite web |last=Prasad |first=KV |date=2013-12-25 |title=MoD clears Navy plans to get 16 shallow-water anti-sub vessels |url=https://www.tribuneindia.com/2013/20131226/main5.htm |url-status=live |archive-url=https://web.archive.org/web/20250829044614/https://www.tribuneindia.com/2013/20131226/main5.htm |archive-date=2025-08-29 |access-date=2025-09-15 |website=Tribune India}}</ref>

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 Shipyard|Pipavav Defense and Offshore Engineering]], [[Goa Shipyard]] (GSL) and Garden Reach Shipbuilders & Engineers (GRSE), for the procurement of the 16 anti-submarine vessels.<ref>{{Cite web |date=2014-06-18 |title=India issues $2.25bn tender to procure ASW shallow-water craft |url=https://www.naval-technology.com/news/newsindia-issues-225bn-tender-to-procure-asw-shallow-water-craft-4297624/ |url-status=live |archive-url=https://web.archive.org/web/20250915131157/https://www.naval-technology.com/news/newsindia-issues-225bn-tender-to-procure-asw-shallow-water-craft-4297624/ |archive-date=2025-09-15 |access-date=2025-09-15 |website=Naval Technology}}</ref>

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 {{INRConvert|5400|c|year=2017|mode=historical}} while GRSE had to match the bid value of CSL in order to get the contract.<ref>{{Cite web |date=2018-01-16 |title=Garden Reach Shipbuilders set to win ₹5,400-crore Navy order |url=https://www.thehindubusinessline.com/economy/logistics/garden-reach-shipbuilders-set-to-win-5400crore-navy-order/article10035674.ece |access-date=2025-09-15 |website=BusinessLine |language=en}}</ref>
