INS Triput is the lead ship of the Triput-class stealth guided-missile frigates (Project 1135.6 follow-on) constructed by Goa Shipyard Limited (GSL) for the Indian Navy. Named after the "mighty arrow" in ancient Indian literature, Triput is the first frigate of the Talwar class to be manufactured indigenously in India.

The frigate is designed for multi-domain combat operations against enemy surface ships, submarines, and air threats in blue-water environments.

History

Background and Procurement

On 25 January 2019, the Ministry of Defence signed an inter-governmental contract with Goa Shipyard Limited for the indigenous construction of two Project 1135.6 follow-on frigates under a technology transfer agreement from Russia. The remaining two ships under the four-ship deal (including INS Tushil) were constructed at the Yantar Shipyard in Kaliningrad, Russia.

Constructed under the "Make in India" and "Aatmanirbhar Bharat" initiatives, a significant portion of the ship's equipment, including weapons, power generation, steering, and air conditioning systems, was sourced from Indian defense manufacturers.

Construction and Launch

The keel for Triput was laid down on 29 January 2021 at Goa Shipyard Limited. The vessel was officially launched into the water on 23 July 2024 by Rita Sreedharan, in the presence of Goa Governor P. S. Sreedharan Pillai.

Following fitting out and harbor trials, Triput underwent sea trials in preparation for commissioning into the Indian Navy's surface fleet.

Design and Capabilities

Characteristics

Triput has a displacement of approximately 3,600 tonnes, an overall length of 124.8 metres (409 ft 5 in), and a beam of 15.2 metres (49 ft 10 in), with a draught of 4.5 metres (14 ft 9 in). The hull incorporates reduced radar cross-section (RCS) stealth features to diminish radar, infrared, and acoustic signatures.

The propulsion system uses a COGAG configuration consisting of two DS-71 cruise gas turbines and two DT-59 boost gas turbines, delivering a top speed of 28 knots (52 km/h) and an operational range of 4,850 nautical miles (8,980 km) at 14 knots (26 km/h).
