Thanks Spaz and George, we're left with the same conclusion though, the 'B' is the runt of the litter, I can see how it was seen as a Harrier replacement in the Battlefield support role, exactly what the USMC require it for. However, it's now regarded as the replacement for the Tornado GR4, if we're getting 138, which I'll believe when I see, I think over 50% of them should be F-35As. Because apart from the party piece the 'B' is a poor relation to the 'A' and 'C'.
