Although the delivery of support activities is also managed by teams within DE&S, the planning process for these functions is somewhat different to that used for procurement.
Responsibility for the support of in-service equipment is split between Front Line Commands (who plan for the first four years) and the Head of Capability (who is responsible for the following six years).
For new equipment, all planning relating to support remains with the Head of Capability until it has been in-service for four years. After that, the equipment is considered to be in-service and its support is managed as such. Therefore over time all equipment support planning will transition to the Head of Capability.
