The Hawk 128 Advanced Jet Trainer is in the process of being introduced into service and has only flown 450 hours in FY 2009-10. A mature estimate of flying hour costs will only be available once it is fully in-service which is not expected until 2012-13.

The average operating cost per hour for the Reaper Urgent Operational Requirement is not held centrally and could be provided only at disproportionate cost.
