Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many and what proportion of Royal Navy sailors are available for time at sea.

As of the 24 January 2024 the number of fully trained and deployable Royal Navy sailors is 19,470 which is 86% of the total Royal Navy regular population.

All personnel rotate periodically through both shore and sea based posts - both of which contribute to Royal Navy outputs. This also allows personnel to take well deserved leave, and to conduct necessary training.
