Would wing turrets help G3 cover the aft arcs blocked for its third main turret?
Short answerNo. Wing mounts are rejected, and the related N3 layout also has a funnel and high superstructure obstructing stern fire.
NotesReplacing the third turret with wing mounts is rejected as a cure for G3's poor aft arcs. N3 also has a funnel and raised superstructure behind its main battery. Those structures obstruct the line of fire toward the stern. An aft engagement remains a weak position for these layouts.
