While Helicopter platforms are flown by all three Services their support funding is programmed only by the Army and Royal Navy. The costs incurred with industry for helicopter support in financial year 2013-14 - the last year for which audited costs exist - was £253 million for the Army and £461 million for the Royal Navy. This includes all spend with industry associated with the delivery of our helicopter activity, including the cost of repair and overhaul of aircraft and capital spares, replenishment of consumable items, technical advice, post design services and, for some platforms, the provision of synthetic and other training services. As these services are typically contracted together, with payment primarily linked to the achievement of flying activity, the costs are not separately recorded. These support services are primarily delivered at contractor sites (including in Yeovil, Gosport, Almondbank and Oxford) and at helicopter main operating bases, with repair and overhaul of sub-components taking place at numerous sub-contractor locations in the UK and abroad. Maintenance services are also provided by military manpower at operating locations in the UK and abroad, but the costs associated with this are not included in the above figures as this information is not routinely collected.
The majority of support activity associated with our helicopter fleets - not including the contribution made by military manpower - is delivered through long-term availability contracts where payment is largely linked to flying output. As such, we do not routinely collect data that would enable the separation of maintenance costs from the costs of repairing aircraft and capital spares, replenishment of consumable items, technical advice and post design services. However, all of these other activities contribute towards the overall helicopter maintenance effort.
