I strongly doubt that, B for the Carriers, A for the RAF(
tbd in 2015), definitively no C version.
My apologies, we are both wrong.
A for USAF (conventional, fixed wing), B for USMC & RAF/FAA (hovery version) and C for USN (conventional with wing fold). Labour ordered the B, the Tories changed their mind and went for the C variant, before changing their minds back again to the B variant. The RAF might have suggested a split buy and want the A but don't hold you breath.
