Different class if Aircraft, at leats in AAO.
For the heavy strategic bombers there is a need, because unlike OTL, the TSR2 is a conventional tactical bomber. It is nuclear capable, but mainly meant for interdiction, i.e. conventional, low-level attacks against bridges, depots and the like.
Hence the name I chose.
Well, I believe the M4 can also do what the Mosquito is meant to do.
like the roles you mention here. Also why don't you named it Mosquito II in honour of its ww2 counterpart?
