Except that the RAF specifically wants Dave-Bs to replace their GR7/9s... irregardless of CVF or not.
And then there is the USMC... which is scheduled to get about 4 times the UK's total Dave buy... and they want Dave-Bs only!
And the Italians & Spanish who want Dave-Bs for the nice new light carrier/amphib combos they specifically designed to fly to fly that aircraft?
No, CVF is a minor driver for Dave-B... it would have been developed if CVF had never been authorized and the RN was to go all-helo, and it won't be cancelled even if CVF is.
