I wonder what happened to the rumored RSAF order during the Singapore Airshow, hopefully the RAF grounding hasn't effected the deal. The next two days of the airshow are public days so I doubt that they'll announce anything there. On a side note there was a UAE A330 MRTT parked at the civilian airport earlier in the week (no idea if it is still there).
Now that military versions have been transferred from Airbus to Airbus Defense and Space, I wonder how those sales will be taken account of in Airbus' order and delivery book. Will they be listed as internal sales to Airbus Defense and Space ?
Oh, yes, but whenever a derivative of a commercial aircraft is sold, it has to be produced by Airbus, since there is only one assembly line for all products.
For comparison, I think the usual industry practice for business jets is to produce a "barebone" aircraft on order and specs from the private/corporate jet subsidiary. The latter takes delivery and is in charge of a transfer to an outfitter, and of delivery to the customer.
The same process might apply to MRTT sales, since Airbus must remain in charge of all A330 production. The difference, though, is in specs and outfitting.
