My Lords, as the noble Lord is only too well aware with his enormous experience, the normal operational cycle of every ship involves them entering different readiness levels depending on their programmes and departmental planning requirements. He is right that the Type 45 has experienced some equipment reliability issues, including with the power and propulsion systems, but I am glad to tell him that most of them have now been remedied and work is continuing to resolve the remaining issues. Notwithstanding the issues that I have referred to, the Type 45 class remains operational and has certainly demonstrated its capability in the time that it has been in service.
