davejb, I remember an air test in a Mk 1 to 410. Really wallowing then. Buy why fly at 410?
Radar horizon at 400 is 240. As an ASW platform it was no advantage being 7 miles from the action. For ASuW it just put you into the EW bracket earlier than need be.
As for the range, the BBC was always interested in how far we had flown and always noted the air mileage flown for their travel claims.
