Question to the Ministry of Defence:

To ask the Secretary of State for Defence, whether his Department has considered replacing the mark 1 30mm cannon on the Type 45 with the DS30M mark 2.

The Ministry of Defence keeps the capabilities of all Royal Navy platforms under regular review to ensure they remain aligned with operational requirements. The Type 45 Destroyers are equipped with a range of layered defensive systems that continue to meet current operational needs.

Any future consideration of alternative weapon systems would be assessed against cost, capability need, platform integration requirements, crew impacts, and overall value for money in the context of the developing Defence Investment Plan.
