The Water Jet Fast Attack Craft (WJFAC) Tihayu, built by the Garden Reach Shipbuilders and Engineers Limited (GRSE) in Kolkata, was handed over to the Indian Navy on August 30, 2016. The warship was handed over by Rear Admiral A.K. Verma, (Retd) Chairman & Managing Director of GRSE to the Commanding Officer of the ship Cdr. Ajay Kashov, at a ceremony held in GRSE. Rear Admiral S.R. Sarma, Chief Staff Officer (Technical) of Eastern Naval Command, carried out final inspection of the ship prior to acceptance by the Navy.

GRSE had earlier built and delivered 10 WJFACs to the Indian Navy during 2009 to 2011, which are proving well in service. Indian Navy has placed order for four more of these WJFACs as ‘follow-on’ ships. The first ship of the ‘follow-on’ series of WJFACs INS Tarmugli was commissioned into the Indian Navy on May 23, 2016. The second FAC Tihayu has been delivered by GRSE. These ships are a further improved version of fast-attack crafts earlier built by GRSE for the Indian Navy. The ship has an efficient hull form developed by the inhouse Design Centre of GRSE and proved by extensive model testing, to achieve speeds in excess of 35 knots. This warship measuring 48 x 7.5 m with a displacement of around 315 tonnes has an endurance of around 2,000 nautical miles at 12-14 knots speed. She also boasts of modern habitability conditions with accommodation for 29 personnel. Named after an island in the Andaman, Tihayu is fitted with three water jet propulsion systems powered by marine diesel engines generating 2,720 kW of power. It is also fitted with CRN-91 indigenous 30mm gun to provide artillery fire support during attack missions.
