How might HMS Hood's Mark II turrets have changed in a major reconstruction?
Short answerThey would probably have been upgraded much like the Mark I turrets, including elevation to roughly forty degrees.
NotesHood's Mark II turrets would probably have been upgraded along the same general lines as improved Mark I mountings. The clearest change would be increasing maximum gun elevation to around forty degrees. That modification would extend useful range without requiring an entirely new main battery. A reconstruction could preserve expensive turret machinery while updating its tactical performance.
