I can post a copy of the BAe letter to the PM dated 6 October 2010 that was leaked if you are not convinced. It confirms the request was for cancellation costs in respect of Prince of Wales alone.
If you can't find this from searching the web let me know and I will do so.
As to posture, I would have liked to seen that of Tornado pilots returning from their bladder testing Strom Shadow sorties.
