Maintenance of the RAF VC10 fleet is provided by BAE Systems under a partnering agreement called JAVELIN (joint approach to VC10 engineering and logistics integration). Logistic support for the Conway engines used on the VC10 is provided by Rolls-Royce plc and engine repairs are undertaken by Vector Aerospace.
The RAF TriStar fleet is supported by the TriStar integrated operational support contract (TRIOS) with Marshall of Cambridge (Aerospace) Ltd. TRIOS excludes the RB211 engines which are contractually supported by Rolls-Royce plc, the auxiliary power units which are contractually supported by Euravia and the air-to-air refuelling equipment which is supported under the VC10 JAVELIN contract.
The cost of these contractual support arrangements is contained in the following table:
