Cleaning the house
From the technical standpoint the RAF is cleaning the house and is fully aware of the shortcomings of some of the contractors, unfortunately just shutting down a poorly performing contractor is not instantly posable because a replacement contractor has to put the manpower in place to take on the work, this can't be done overnight added to this some sort of handover of official documentation ( assuming it has not been lost) has to take place when contractors change.
With Babcock getting the Viking recovery job ( the fleet with the long term future ) it would appear that this process of contractor change is underway.
The support contract tender document will be released soon and this will give all party's the chance to bid, no doubt the past performance and performance on other contracts will come into play when choosing a contractor for the support contract.
It would be interesting to see the odds Paddy Power would give on the uncumbent contractor getting the support contract !
