How did the RAF manage to De-marinise a marinised airframe in the first place? Surely the things could have been bought as per the HM1 but with a rear ramp and the heavy bits of the tail folding mechanism removed in favour of bolts and some buttstraps.
... A simplistic comment I know but I cant help but think there was a certain degree of "these are our toys so we're going to spec them so the Navy cant use them" mentality going on.
