Mine Hunting Capability, the Royal Navy's programme replacing crewed minehunters with autonomous systems, has a mothership deck-space shortfall: an 11 August 2026 assessment set its Block 2 minimum at 1,000 square metres against HMS Stirling Castle's roughly 600.

Autonomous Systems: Land & Sea: UK to buy three Norway mothershipsBackground
The Mine Hunting Capability programme is the Royal Navy's transition plan from crewed Hunt-class minehunters to autonomous mine-countermeasures systems and the motherships that launch, recover and command them at sea. UK Defence Minister Luke Pollard confirmed on 17 July 2026 that Britain will procure three further offshore support vessels jointly with Norway, a GBP 90 million tranche within the programme's wider GBP 1.3 billion budget.
An 11 August 2026 assessment set the programme's Block 2 requirement at a minimum 1,000 square metres of mothership deck space, against first-of-class ship HMS Stirling Castle's roughly 600, and weighed the GBP 90 million Norway tranche against a fuller three-hull build estimated at roughly GBP 330 million, with the Hunt-class due out of service by 2032.
Block 2 needs more deck space
An 11 August 2026 assessment by Navy Lookout set the Mine Hunting Capability programme's Block 2 mothership requirement at a minimum 1,000 square metres of deck space, more than the roughly 600 square metres offered by first-of-class ship HMS Stirling Castle.
The same assessment weighed the GBP 90 million Norway funding tranche, confirmed 17 July 2026, against a fuller three-hull build estimated at roughly GBP 330 million, with the Hunt-class due out of service by 2032. The comparison leaves the programme's near-term mothership capacity short of what its own next stage requires.
