Building RFA Resurgent: three yards, 9,000 square metres of munitions space, and a workforce question from 1994

Technical Summary

RFA Resurgent, first of three Fleet Solid Support (FSS) ships, is now in fabrication across three yards in two countries. Navantia UK is erecting the two forward modules at Appledore. The three central modules containing the main cargo holds will be built at Harland & Wolff in Belfast. The two aft modules, machinery spaces and superstructure, are being cut in Cádiz. All seven modules will be integrated in Belfast, where test blocks for Ship 2 are already in fabrication. The NUK Seahorse blocks barge arrived at Appledore in early June 2026. Defence Equipment & Support (DE&S) placed the £1.6 billion manufacture contract with Team Resolute (Harland & Wolff, Navantia UK and designer BMT) in January 2023; Navantia UK bought Harland & Wolff out of administration in January 2025. Commodore Sam Shattock, the Royal Fleet Auxiliary’s head of service, named the first ship at the Appledore steel-cutting ceremony on 3 December 2025. DE&S expects her in service by 2031, with all three ships accepted by 2032.

The ships themselves are the largest dry stores vessels the Royal Fleet Auxiliary (RFA) has ever operated: 216 m long, 34.5 m beam, displacing 39,000 tonnes, with around 9,000 square metres of cargo space for ammunition, spares and provisions, against an original 2018 requirement framed volumetrically at up to 7,000 cubic metres. That is roughly three times the solid stores capacity of RFA Fort Victoria, the ship they replace. Two cost decisions made early in the programme shape everything that follows. The 5-tonne heavy replenishment rigs were deleted, leaving three rigs passing 2.5-tonne loads. And the automated weapon handling system fitted in the Queen Elizabeth-class carriers was removed from the specification, so every pallet of cargo will move by conventional mechanical handling equipment and lifts, exactly as in Fort Victoria today. A core ship’s company of 101 RFA personnel, with accommodation for around 80 more, will operate them.

The design deleted the automated handling system to save money. Every pallet in 9,000 square metres of cargo space will move by forklift, lift and human judgement. The ship assumes a trained stores department; the nation disbanded its professional afloat armament supply cadre in 1994. ISC open-source assessment, June 2026

The Department That No Longer Exists

When the RFA last ran purpose-built ammunition ships at full stretch, their storerooms and magazines were not the RFA’s alone. Fort Grange and Fort Austin sailed with a three-part complement: RFA officers and ratings, a Royal Navy air department, and an embarked civilian stores department drawn from the Royal Naval Supply and Transport Service (RNSTS), known on board as the STO(N) (Supply and Transport Officer (Naval)) department. Published complements list around 36 STO(N) civilians per ship. These were career armament supply professionals from a service formed in 1965 out of the Admiralty’s stores, victualling and armament supply directorates, a service whose December 1981 establishment return listed some 13,000 staff across the Royal Naval Armament Depots, stores depots and naval base organisations. In 1982 it supplied the Falklands Task Force and took up more than 50 merchant ships from trade; the Permanent Under Secretary signalled afterwards that without the RNSTS the outcome “might well have been jeopardised”.

The RNSTS was wound up in 1994 and its functions dispersed. Depot and base supply passed through the Naval Bases and Supply Agency, launched in December 1996 with 13,350 staff, then into the Warship Support Agency, the Defence Logistics Organisation and finally DE&S. The armament depots became today’s seven Defence Munitions sites, holding around 1,100 civilian staff at the last published count in 2018. Commodity storage and distribution, including munitions freight, went to Leidos in 2015 under the 13-year, £6.7 billion Logistic Commodities and Services Transformation contract. Afloat, the embarked civilian departments simply ceased. Their duties folded into the RFA’s own small logistics branch, today recruited as Logistics Supply Officers and Supply Chain Operatives. No like-for-like seagoing armament supply profession was ever reconstituted.

Analysis of Effects

The industrial half of the programme is the good-news story. Belfast employed roughly 50 people when Harland & Wolff entered administration in 2019; the yard now employs around 450, recruits 50 to 60 apprentices a year, and has absorbed close to £100 million of investment in panel lines and Navantia’s digital shipyard model. Delivering three ships will require around 800 tradespeople plus 400 programme staff on the site. The seagoing workforce that must operate those ships tells a different story. RFA strength fell from about 2,300 in December 2010 to 1,750 in May 2023, a decline of roughly a quarter. In June 2025 the Commons was told that only six of eleven RFA ships were operational and that skilled cadres were understaffed by 30 to 50 per cent. RFA officers struck for the first time in the service’s history in August 2024. A pay settlement followed in January 2025, yet RMT members walked out again for 24 hours on 12 May 2026. There are recovery signs: outflow has fallen from around 15 per cent to under 10 per cent a year, the workforce is growing again, and an additional ship, RFA Tiderace, is due to be crewed later in 2026.

The solid stores skills base is the sharpest edge of this problem. Fort Victoria, the RFA’s only solid support ship, has not transferred solid stores at sea since early 2022 and was laid up at Liverpool in late 2024 for want of a crew; the 2025 Carrier Strike Group deployed to the Indo-Pacific leaning on a Norwegian auxiliary for solid support. Her refit from September 2026 and possible return in 2027 is explicitly framed by the head of service as the means to generate suitably qualified and experienced personnel for the FSS ships. Until RFA Resurgent is delivered and proven, that one hull is also the single point of failure: if the refit or its crewing slips, solid stores support to the Carrier Strike Group continues to rest on allied auxiliaries. The arithmetic is demanding. Three ships at 101 core crew each, with rotation, training and shore margins, implies a trained pool several times that figure, and within it a stores department able to plan, stow, account for and issue the contents of the largest RFA magazines ever built. By first-of-class delivery in 2031, the service will have had at most four years of single-ship regeneration to rebuild a competence that once rested on a dedicated profession.

Personnel and Safety Considerations

Regulation has not relaxed to match the thinner workforce. The Defence Ordnance, Munitions and Explosives Safety Regulator (DOSR), within the Defence Safety Authority, requires duty holders to discharge ordnance, munitions and explosives (OME) responsibilities through suitably qualified and experienced personnel (SQEP) under DSA 02.OME; storage and processing practice sits in DSA 03.OME Part 2, successor to the withdrawn JSP 482. RFA vessels operate under BRd 875 with Maritime and Coastguard Agency oversight through the annual Document of Compliance audit. The shore interface remains professionally strong: Defence Munitions Gosport staff run ammunitioning at Portsmouth’s Upper Harbour Ammunition Facility, and the rebuilt £67 million Glen Mallan jetty, completed in January 2022, embarks munitions road-delivered from DM Glen Douglas for the carriers. None of those civilian specialists sails with the ship.

At sea the workload lands on the embarked department: stowage planning and compatibility segregation across 9,000 square metres of mixed natures, magazine inspection and environmental routines, explosives accounting, building and breaking replenishment loads, and feeding a carrier air wing’s weapons demand at tempo, potentially during combat operations. Deleting the automated handling system held down unit cost and pushed the burden back onto people: pallets move by forklift and lift under human supervision. The design therefore assumes precisely the kind of trained, current, explosives-aware stores department that the service has not had to generate at scale since 1994.

Data Gaps

The MoD has not published the departmental breakdown of the 101-strong core complement, so the planned size and trade structure of the FSS stores department is unknown. The current RFA strength figure for 1 April 2026 sits in statistical annexes rather than the published bulletin and is not quoted here. The afloat explosives storage publication set is not publicly available, so stowage and licensing detail for the class cannot be assessed from open sources. The number of RNSTS civilians embarked across the 1982 Task Force is not recorded in accessible sources. Ship 3 remains under contract but subject to credible cancellation rumours; termination would yield modest savings since the contractor would recover costs incurred.
