Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many Royal Navy destroyers and frigates were fully operational and deployable at immediate readiness in each of the last 12 months.

The Royal Navy maintains a high state of operational readiness across its core capabilities, including the Continuous At Sea Deterrent, Carrier Strike, frigates and destroyers, submarines, aviation, the Royal Marines and the Royal Fleet Auxiliary. The Fleet is deployed globally to protect the UK’s security and interests, working alongside allies and partners.

It is important to understand readiness as a constant cycle with ships moving regularly through maintenance, training, deployment and recovery phases. For reasons of operational security, the Ministry of Defence does not give detailed information on past or current levels of readiness for individual Royal Navy warships.
