Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to his Department's press release entitled UK and Norway to operate together to counter Russian undersea threat through major new defence agreement, published on 4 December 2025, how many offshore support vessels will be delivered as part of the Lunna House agreement.

The Lunna House announcement on 4 December 2025 highlighted the UK's intent, conveyed to the Prime Minister of Norway, Jonas Støre, to deliver the Offshore Support Vessel as the mothership for the Mine Hunting Capability programme. The exact number of Offshore Support Vessels will be determined as part of the Defence Investment Plan and in conjunction with our Norwegian allies.
