Amid the noise surrounding the Defence Investment Plan, the hybrid navy concept, and the cancellation of the Type 83 destroyer, one story has been easy to miss: the Type 31 frigate programme is actually going to plan.
HMS Active, the second of five Inspiration-class frigates, was rolled out of its construction hall at Babcock’s Rosyth facility in February 2026 and floated from its submersible barge the following month. Meanwhile, construction of HMS Bulldog – the fourth ship in the class – began in the same period, meaning that three of the five Type 31s are simultaneously in various stages of production. For a UK warship programme, that degree of concurrent activity is worth noting.
Why Type 31 matters
The Type 31 programme was conceived as a deliberate corrective to the cost spiral that has afflicted high-end UK warship procurement. Where the Type 26 anti-submarine warfare frigate is a highly capable but expensive and complex platform being built at a rate of roughly one per year on the River Clyde, the Type 31 is designed for lower-cost high-volume production – an austere general-purpose frigate intended to free the Type 26 for the most demanding ASW tasks while taking on maritime security, allied engagement, and presence patrols.
At 5,700 tonnes and 138.7 metres, the Type 31 is a substantial vessel. It carries the MBDA Sea Ceptor air-defence missile system with 32 vertical-launch cells, a 57mm Mk110 main gun, and two 40mm Bofors guns. It accommodates a helicopter and drones, and is built around the Thales TACTICOS combat management suite. The complement is around 110 personnel, with accommodation for up to 190 – reflecting a design that anticipates augmented crew for operations.
The five ships are HMS Venturer, Active, Formidable, Bulldog, and Campbeltown. Venturer, the first of class, is expected to commission in 2027 after outfitting and sea trials in 2026.
The Rosyth investment
The programme has had a significant industrial effect at Rosyth in Fife, where Babcock International is building all five ships. The facility underwent significant investment to support the Type 31 programme, and the concurrent production of multiple hulls is demonstrating that the UK is capable of maintaining a meaningful shipbuilding throughput – something that has been in doubt for much of the past two decades.
The programme has also attracted export interest. The Arrowhead 140 design – the commercial parent of the Type 31 – has won export orders from Poland and Romania, providing Babcock with an extended production run that helps maintain the industrial skills base between UK orders.
The quiet programme
Type 31 rarely generates the headlines that Type 26 or the cancelled Type 83 attract. It lacks the drama of a troubled programme or a major cancellation. It is simply a frigate programme that was designed to be affordable, is being built on schedule, and is delivering ships. In the context of UK defence procurement history, that is itself remarkable – and probably worth more attention than it gets.
The Royal Navy starts to look meaningfully different as Type 31s enter service alongside the Type 26s currently building on the Clyde. Five additional general-purpose hulls, deployable globally, substantially increases the Navy’s ability to sustain presence operations without degrading its high-end warfighting capability. That’s exactly what the programme was designed to do.
