Two 1945 Lion-class battleships could dismantle the High Seas Fleet at night

Which later Lion concept would have the most impact if it replaced the First World War battlecruisers with 1945 fire control and radar?

The selected concept has thirty-knot speed and nine 16-inch guns; an overwhelming night-fighting advantage is expected, while submarines remain a threat.

A pair of late-war Lions could wait for darkness and close on the High Seas Fleet using radar that the Germans could not match. Their speed would let them choose the range and prevent older capital ships from escaping. Nine 16-inch guns would provide the main destructive weight, while radar-directed 5.25-inch batteries would reduce the threat from torpedo craft. With a destroyer screen against submarines, the force could press much farther into German-controlled waters than a First World War battle squadron.
