These figures do not include aircraft in the depth fleets or the eight RAF Chinook Mark 3 helicopters that are being converted to a battlefield support role. Two of the six ex-Danish Merlin helicopters have now entered squadron service and are included in the above figures.

The figures do not reflect the fact that unserviceable aircraft can often, if required, be made serviceable at very short notice to meet the operational need.
