The Trinkat-class patrol vessels of the Indian Navy were designed and constructed by Garden Reach Shipbuilders and Engineers.
The patrol vessels carry out fisheries protection, anti-poaching, counter-insurgency and search-and-rescue operations in coastal areas and in the exclusive economic zone. The vessels of the "Trinkat" class are named after islands from the Andaman and Nicobar Islands or the Lakshadweep Islands.[citation needed]
While the older INS Tarasa and INS Tarmugli were transferred to Seychelles Coast Guard and INS Tillanchang was transferred to Maldivian Coast Guard, newer ships bearing the original names were launched starting in 2016. The new ships have also been designed and constructed by Garden Reach Shipbuilders and Engineers as Car Nicobar-class patrol vessels. The new INS Tarasa (T94), the follow-on water jet fast attack craft was launched in Kolkata on 30 June 2016. The new INS Tillanchang (T92) another water jet-powered fast attack craft was commissioned at Karwar on 9 March 2017. The new INS Tarmugli (T91) was commissioned at Vizag on 23 May 2016.[3] These ships are similar in design and armament to the Trinkat-class ships that were transferred to Maldives and Seychelles, with added capabilities for enhanced endurance.
The newer INS Tarmugli (T91) was donated to the Maldives in May 2023.[4][5] The older MCGS Huravee (formerly INS Tillanchang) was transferred back to India, and after inspection, was decided to be refitted and recommissioned. Subsequently, on 14 December 2023, the former Tillanchang was recommissioned into the Indian Navy as INS Tarmugli.[6]
