All Royal Navy (RN) ships rotate through planned operating cycles involving maintenance, repair, training, deployment, leave and upgrades. This results in individual ships being at various levels of readiness at any one time in accordance with the long-term operating schedule and operational needs; they remain in service during these periods. These periods are necessary for any highly complex system maintenance and are essential to ensure ships are fit for purpose in the most hostile of operational environments. In addition, the periods provide an opportunity to complete modifications and to fit essential upgrades to systems.
Repair work on individual ships and their systems takes place during both planned maintenance periods and operational deployments. It is our policy to not disclose the readiness state of individual ships as this would, or would be likely to prejudice the capability, effectiveness or security of the Armed Forces. However, currently the following RN ships are undertaking routine docking or their deep refit period and are therefore unavailable for operational tasking:
HMS RICHMOND; HMS DAUNTLESS; HMS PEMBROKE; HMS LANCASTER; HMS SOMERSET; HMS PORTLAND; HMS MIDDLETON; HMS IRON DUKE; HMS DARING
Maintenance of Royal Navy warships is funded through an In Service Support allocation of Naval funds through a Maritime Support Delivery Framework contract.
