Fleet Solid Support Ship

Fleet Solid Support Ship. The Fleet Solid Support Ships are a new class of three Royal Fleet Auxiliary vessels designed to provide crucial logistical support to the Royal Navy's aircraft carriers and escort groups. These ships will transport and transfer dry stores, ammunition, and spare parts, forming a key component of the United Kingdom's Carrier Strike Group capability. The programme represents a significant investment in national maritime support and has been developed through a complex international partnership.

Design and specifications

The design is based on the proven BMT Aegir support ship concept, adapted by the prime contractor Team Resolute. Each vessel will measure 216 meters in length with a beam of 34.5 meters and a displacement of approximately 40,000 tonnes. Propulsion will be provided by a diesel-electric system, enabling a sustained speed of 18 knots, suitable for keeping pace with a task force. The ships will feature extensive cargo holds for palletised and containerised stores, advanced transfer systems including replenishment at sea rigs, and a large flight deck capable of operating heavy-lift helicopters like the Merlin and Chinook. The design emphasises efficiency and incorporates features to support operations in varied climates, from the North Atlantic to the Persian Gulf.

Procurement and construction

The procurement process for the vessels was lengthy and politically contentious, involving debates over national security and domestic shipbuilding capacity. After initial competition, the contract was awarded in 2022 to Team Resolute, a consortium comprising British firm Harland & Wolff, Spanish shipbuilder Navantia, and British design house BMT Group. The Ministry of Defence contract is valued at approximately £1.6 billion. The construction will utilise a blended approach: the bow sections and other blocks will be fabricated at Harland & Wolff's facilities in Belfast and Appledore, while the majority of the ship structure will be built by Navantia in Cádiz, Spain. Final assembly, integration, and testing will occur at Harland & Wolff's yard in Belfast.

Role and capabilities

The primary role is to supply the Queen Elizabeth-class carriers, Type 45 destroyers, Type 26 and Type 31 frigates with the solid stores necessary for prolonged deployments. This includes transferring munitions, food, spare parts, and other consumables via replenishment at sea operations using both connected rig and vertical replenishment by helicopter. This capability is essential for maintaining the endurance and global reach of a Carrier Strike Group, allowing it to operate independently of fixed port facilities. The ships will be crewed by civilian personnel of the Royal Fleet Auxiliary and will work in close coordination with the Royal Navy's Tide-class fleet tankers, which provide liquid fuels.

Operational history

As of 2024, the ships are under construction and have not yet entered service. The first steel was cut for the initial vessel in 2023 at the Navantia shipyard in Cádiz. The lead ship is scheduled for launch in 2026, with delivery to the Royal Fleet Auxiliary planned for 2028. Upon entry into service, they will undergo extensive sea trials and work-up periods, likely operating initially from the RFA's main base at HMNB Devonport. Their first major operational deployment is expected to be with a Carrier Strike Group, potentially on a global deployment similar to CSG21, the inaugural deployment of HMS *Queen Elizabeth* to the Indo-Pacific.

International comparisons

Similar solid support capabilities are maintained by other major naval powers. The United States Navy operates the larger Lewis and Clark-class (T-AKE) and the newer John Lewis-class (T-AO) ships with its Military Sealift Command. The French Navy is supported by the Jacques Chevallier-class Bâtiment ravitailleur de forces, built in partnership with Italy. The Italian Navy operates the Vulcano-class. The Japan Maritime Self-Defense Force fields the Mashū-class. Compared to these, the British ships are specifically tailored to support the large air groups and escort screens of the Queen Elizabeth-class, with a significant focus on ammunition transfer and helicopter operations.
