Peter We - the number of countries who would only buy Dave-B is pretty small - Italian and Spanish navies? (On the unlikely assumption that these two countries will be able to afford a £100m STOVL strike fighter.)
Israel wanted some as a mix/match with -As (IIRC). We have decided it is a cunning plan as we won't make the savings to refit CVF. Maybe the Aussies (off the Canberra LHD) or the Japanese (off their Hyuga-class "not carriers").
But these sales will be peanuts, and no reason at all for the US to continue with the -B unless the USMC really needs it.
