Rajnath Singh launches fleet support ship Surya at Visakhapatnam

Defence minister Rajnath Singh launched Surya, the first of five fleet support ships for the Indian Navy, at Hindustan Shipyard in Visakhapatnam on Tuesday. He laid the keel of the fifth ship in the class and inaugurated an upgraded Slipway-4 and a 300-tonne Goliath crane at the same yard. He then flew to Koraput in Odisha to mark delivery of the 2,000th aero-engine from Hindustan Aeronautics.

The ship is a replenishment oiler, not a combatant. Its job is to keep a task group at sea by passing fuel, fresh water, ammunition and dry stores, and by offering a limited workshop. The Navy's existing Deepak-class tankers do this work now. The Surya class is meant to replace and enlarge that capacity. Public figures for the design put displacement at 43,500 tonnes, length at 223.6 metres, beam at 31.5 metres and draught at 9.3 metres, with a double bottom and a double hull. Earlier descriptions rounded the length to about 230 metres and displacement to about 45,000 tonnes. Either set makes these the heaviest support ships the Navy has ordered, and among the largest hulls it will take before 2030.

The money was cleared in stages. The government approved the project on 16 August 2023 at a cost then stated near 20,000 crore rupees. The contract with Hindustan Shipyard for five ships was signed on 25 August 2023 at 19,000 crore rupees, about 3,600 crore a hull. Deliveries are scheduled to begin in mid-2027. Four ships are in build. One, Surya, is now in the water. Indigenous content on the first ship was put at 82 percent at the launch.

The design path is part of the industrial story. The ships were at one point to be designed in Turkey. They were instead drawn by Smart Engineering and Design Solutions, a naval architecture firm in Kakkanad, near Kochi, working with the yard's own team. Hindustan Shipyard is the builder in Visakhapatnam. Larsen and Toubro's Kattupalli yard has also been named in class summaries as a builder. The slipway and the crane inaugurated on Tuesday are the yard's answer to the size of the hull. A 43,500-tonne ship does not fit the old workflow. Singh called the launch a mark of achievement, the keel of the fifth ship a mark of resolve, and the new slipway a mark of capacity. The three events were priced as one day so that the ministry could show a ship in the water, a ship still on paper, and the tool that builds both.

A fleet support ship changes how long a carrier group can stay out. Fuel is the constraint. A destroyer escorting an aircraft carrier burns through its own bunkers in days if it sprints. Underway replenishment lets the group stay on station without returning to a harbour that may be watched. The Navy has wanted this class since the Deepak ships, INS Deepak and INS Shakti, showed both the value and the limit of two foreign-built tankers. Five indigenous hulls, if they arrive on the mid-2027 start, would give the fleet a rotation: one with each carrier group, one in maintenance, one spare. That arithmetic only works if the yard holds the date. Hindustan Shipyard's record on large hulls is the risk the crane and the slipway are meant to reduce.

The Koraput stop on the same day was a separate programme. The 2,000th aero-engine from HAL is an aircraft-industry milestone, not a naval one. Placing it on the minister's schedule beside Surya ties two public-sector lines, shipbuilding and engines, into a single claim about domestic production. The ship claim is the one that can be checked soonest. A launched hull still has to be fitted out, trialled and commissioned. Mid-2027 is the delivery window the contract summaries give, not the commissioning date.

What Tuesday fixed is the name, the yard, the first hull in the water, the fifth keel, and a published indigenous share of 82 percent. What it did not fix is the month the Navy will actually take Surya, or how the double-hull oiler will be crewed and armed for a sea threat that now includes drones against support ships, as the Black Sea and the approaches to Hormuz have both shown this year. A tanker that cannot defend itself is a magazine with a slow top speed. The launch answers the supply question. It leaves the escort question where it was.
