ROSYTH, Scotland — Feb. 25, 2026 : Babcock International Group has achieved two significant milestones in the Royal Navy’s Type 31 Inspiration-class frigate programme at its Rosyth shipyard in Scotland, marking continued progress under the £1.25 billion contract awarded in 2019.
In a joint ceremony held on February 24, the company completed the structural rollout of HMS Active, the second ship in the five-vessel class, while also conducting the ceremonial steel cutting for HMS Bulldog, the fourth frigate in the series. The milestones reflect steady advancement in construction sequencing and manufacturing efficiency at the purpose-built Venturer Building assembly hall.
Structural Rollout and Construction Progress
HMS Active emerged from the covered assembly facility following completion of its primary structural build phase. The rollout signifies that the ship’s main structural blocks have been integrated and assembled, clearing the way for the vessel to enter the water for the first time before moving into the next stages of outfitting, systems integration, and sea trials.
On the same day, the steel-cutting ceremony for HMS Bulldog formally marked the beginning of fabrication work on the fourth of the five planned Inspiration-class ships. Steel cutting represents the first physical stage of construction, initiating the manufacturing process for hull blocks and structural components.
The five ships in the class are HMS Venturer, HMS Active, HMS Formidable, HMS Bulldog and HMS Campbeltown. HMS Venturer, the lead ship, rolled out in mid-2025. The keel for HMS Formidable, the third vessel, was laid at the end of 2025.
Modular Manufacturing and Facility Investment
The Type 31 programme is being delivered using a modular construction model designed to improve production efficiency and schedule predictability. According to Babcock, lessons learned from the build sequence of the first two vessels have been applied to subsequent ships to streamline integration and reduce bottlenecks.
A greater proportion of compartment assembly and systems outfitting is now being completed within manufacturing bays before the main structural blocks are consolidated in the central build hall. This approach reduces integration time during final assembly and supports adherence to delivery timelines.
Babcock has invested approximately £200 million in upgrading and modernising the Rosyth facility, including the construction of the Venturer Building, which enables the simultaneous assembly of two frigates under cover. The infrastructure supports digital design integration, advanced manufacturing techniques, and improved logistics coordination across the supply chain.
Employment and Industrial Impact
The programme sustains approximately 2,500 highly skilled jobs, with the majority based in Fife, Scotland. Employment extends across a broad network of United Kingdom and international suppliers, including numerous small and medium-sized enterprises (SMEs).
The project is considered a core component of the United Kingdom’s sovereign naval shipbuilding strategy, strengthening domestic capability in the design, integration and construction of complex surface combatants. In addition to industrial employment, the programme supports apprenticeship schemes and engagement with local colleges to develop technical skills.
The Scottish Government has provided more than £90 million in enterprise agency funding since 2006 to aerospace, defence, marine and space companies to reinforce Scotland’s advanced manufacturing base.
Operational Role of the Type 31 Frigates
The Inspiration-class frigates will form a key element of the Royal Navy surface fleet. Designed as versatile general-purpose warships, they are intended to undertake a range of missions including maritime interception operations, intelligence gathering, defence engagement, presence missions, and humanitarian assistance.
Vice Admiral Steve Moorhouse, Fleet Commander, stated that the class has been designed with modularity and adaptability to enable capability upgrades throughout its operational life. The ships’ combat systems architecture is structured to allow incremental enhancements in response to evolving operational requirements.
All five vessels are scheduled to enter service by the early 2030s.
Arrowhead 140 Design and Export Programme
The Type 31 frigates are based on Babcock’s Arrowhead 140 design, a platform that has secured international export contracts. The design has been selected by Poland for its Miecznik frigate programme and has been adopted in Indonesia, where multiple Arrowhead 140-based frigates are currently under construction under licensed design and build arrangements.
The export success of the Arrowhead 140 platform has reinforced the industrial base supporting the Type 31 programme, providing continuity of production expertise and supply chain engagement beyond the United Kingdom order.
With the structural completion of HMS Active and the commencement of fabrication for HMS Bulldog, the Rosyth facility continues phased construction across the five-ship programme as it progresses toward full fleet delivery in the next decade.
