If, as I understand things, several previously Command or Group level functions are now found at Station level, it's not surprising that this would cause changes at the top of what I see is a £1.4bn full-cost operation.
I am, however, intrigued by another bit of p24, where it's stated that work is in hand "to give Defence access to an additional Voyager aircraft," an issue that appears to be linked to a desire to reduce charter expenditure. Other than remarking that this is by no means a new desire, as it came up often enough in the 1970s to my knowledge, are we to take it that this work seeks to increase the Voyager 'Core Fleet' to 10? And that it needs a contract amendment to use one of the 'surge' fleet in a situation short of war?
