Trinkat (Bangaram SDB Mk5)

The Trinkat-class patrol vessels are fast attack craft designed for coastal surveillance, anti-smuggling, and search and rescue operations. They are equipped with light armament for self-defense and interdiction tasks in littoral waters.

Developed by Garden Reach Shipbuilders & Engineers to succeed the older Seaward Defence Boats, the Trinkat-class (including the Bangaram-class SDB Mk5 variants) entered service with the Indian Navy starting in 2000. These vessels were primarily deployed for maritime patrol, fisheries protection, and counter-piracy operations in the strategic waters of the Andaman and Nicobar Command. Demonstrating India's maritime diplomacy, several units of this class were later refurbished and transferred to friendly regional nations, including the Seychelles and Maldives. Today, the remaining active vessels continue to secure India's vast Exclusive Economic Zone, while the transferred units serve as vital assets for neighboring island nations.
