Military Aircraft

Volume 488: debated on Monday 2 March 2009

To ask the Secretary of State for Defence what percentage of (a) the total air transport and tanker aircraft fleet in service and (b) the air transport and tanker aircraft forward air fleet were fit for purpose in each year since 2001, broken down by aircraft type. (258870)

The information requested for the C-17, Tristar, VC-10 and Hercules fleets is provided in the following table. ‘In service’ has been taken to mean the effective fleet, which covers all aircraft barring those which are redundant, declared as surplus or awaiting disposal. Aircraft in the forward fleet (FF) are those that are available to the front line command for operational and training purposes including those that are classed as short term unserviceable; aircraft undergoing scheduled depth maintenance or planned routine fleet maintenance are not included. Aircraft defined as fit for purpose (FFP) are those considered capable of carrying out their planned missions on a given date.

The information requested is not available prior to 2005. Numbers have been rounded to the nearest aircraft.
