If the Carriers are supposed to be doing "useful things"....having half the Carrier Fleet spending extended periods of time in Rosyth for unscheduled repairs puts a very real dent in the ability for "useful things" to be performed?
What happens to that capability if both Carriers are in port for regular maintenance and unscheduled repairs?
Does the ASW function revert to the Frigates and Helicopters?
Does that mean the ASW capability is rendered insufficient as a result?
