The Fleet Support Ship ‘Surya’ (FSS-1), India’s first indigenously built ship of this class, has been launched by Hindustan Shipyard Limited (HSL). This note covers what a Fleet Support Ship does, the five-ship programme, HSL’s status, and the defence-shipbuilding traps that appear in prelims.
Why in News?
Defence Minister Rajnath Singh launched FSS-1 ‘Surya’, the first indigenous Fleet Support Ship for the Indian Navy, at Hindustan Shipyard Limited, Visakhapatnam.
At the same event he:
- laid the keel of the fifth Fleet Support Ship (FSS-5)
- inaugurated the upgraded Slipway-4, which can build ships of up to 45,000 DWT
- inaugurated a 300-tonne Goliath crane made under Make in India
Key Facts for Prelims: Fleet Support Ship ‘Surya’
- Type: An auxiliary (support) ship, not a frontline combat warship
- Builder: Hindustan Shipyard Limited, a Defence PSU
- Programme: Five Fleet Support Ships for the Indian Navy, under a contract signed in 2023 worth about ₹19,000 crore
- Size: Displacement of over 40,000 tonnes
- Cargo: Fuel, aviation turbine fuel, fresh water, ammunition and provisions
- Onboard features: Maintenance workshops, a helicopter deck and self-defence systems
- Status: Launched, not yet commissioned. Deliveries to the Navy are expected from 2027.
What Does a Fleet Support Ship Do?
A Fleet Support Ship is a floating logistics hub. It carries out Replenishment at Sea (RAS): it transfers fuel, water and stores to warships while both ships keep moving.
- Endurance: Warships need not return to port to refuel, so they can stay deployed longer.
- Reach: It extends the Navy’s operating range across the Indian Ocean Region (IOR).
- Blue-water capability: A carrier battle group cannot operate far from home without such tankers.
- HADR: It can carry relief material during Humanitarian Assistance and Disaster Relief missions.
Static Link: Indian Shipyards and Maritime Vision
- Hindustan Shipyard Limited: Started in 1941 as Scindia Shipyard. It has been under the Ministry of Defence since 2010 and received Miniratna Category-I status in 2025.
- Other Defence PSU shipyards: Mazagon Dock Shipbuilders (Mumbai), Garden Reach Shipbuilders and Engineers (Kolkata) and Goa Shipyard.
- Cochin Shipyard, which built the aircraft carrier INS Vikrant, comes under the Ministry of Ports, Shipping and Waterways, not the Ministry of Defence.
- Existing fleet tankers: The Navy already operates replenishment tankers such as INS Deepak and INS Shakti, which were built abroad.
- MAHASAGAR (Mutual and Holistic Advancement for Security and Growth Across Regions) succeeded SAGAR as India’s maritime vision. It was announced in Mauritius in 2025. Support ships help India act as a “first responder” in the IOR.
Ship Launch vs Commissioning
| Stage | What Happens |
|---|---|
| Steel cutting | Construction formally begins |
| Keel laying | The first structural block is placed on the slipway |
| Launch | The hull is floated into water; fitting-out of machinery and systems continues |
| Sea trials | The ship’s systems are tested at sea |
| Commissioning | Formal induction into the Navy; the ship gets the prefix “INS” |
Quick Revision Table: Fleet Support Ship
| Parameter | Fact |
|---|---|
| Ship | FSS-1 ‘Surya’ |
| Category | Fleet Support Ship (auxiliary / replenishment ship) |
| Builder | Hindustan Shipyard Limited (Defence PSU) |
| Administrative ministry of HSL | Ministry of Defence |
| Programme size | Five Fleet Support Ships |
| Contract value | About ₹19,000 crore |
| Displacement | Over 40,000 tonnes |
| Core role | Replenishment at Sea: fuel, water, ammunition, stores |
| Strategic gain | Longer endurance and reach of the Navy in the IOR |
| HSL status | Miniratna Category-I |
Trap / Confusing Points
| Common Confusion | Correct Position |
|---|---|
| Surya has been commissioned into the Navy | No. It has only been launched. Commissioning comes after fitting-out and sea trials. |
| It should be called “INS Surya” now | The prefix “INS” is used only after commissioning. Until then it is FSS-1 ‘Surya’. |
| Surya is the Navy’s first-ever replenishment ship | No. It is the first indigenous Fleet Support Ship. The Navy already runs foreign-built tankers such as INS Deepak and INS Shakti. |
| A Fleet Support Ship is a combat warship | No. It is an auxiliary ship with only self-defence systems. |
| All public sector shipyards are under the Ministry of Defence | No. Cochin Shipyard is under the Ministry of Ports, Shipping and Waterways. |

Exam tip: For defence news, always note the stage (launch, delivery or commissioning), the builder and its ministry. The Fleet Support Ship programme is a likely source of prelims statements.
