The HSL-class fleet support vessels are a series of five fleet tanker planned to be built by Hindustan Shipyard (HSL), Visakhapatnam and Larsen & Toubro at Kattupalli Shipyard for the Indian Navy. The deal was signed on 25 August 2023 with an expected project completion timeline of 8 years. These ships will be an indigenous design by the Hindustan Shipyard's in-house design team. The primary role of the vessels would be to replenish ships of the Indian Navy with fuel, food and various other supplies. With a length of 230 m and displacement of 45,000 tonnes (44,000 long tons), these will be the heaviest and the second largest vessels to be in operation in the Indian Navy fleets before 2030.
