Iowa-class design for task-group warfare

The Iowa's 16-inch/50 battery is defended as a balance of rate of fire and striking power when larger American guns were possible. Its fast task-group role also distinguishes it from ships designed primarily for the battle line. In this historical interpretation, Jutland's concentration depended on Britain and Germany having large fleets directly opposite one another. Global commitments made comparable concentration less practical, and post-World War I exercises pointed toward task groups. Nelson and Rodney illustrate the alternative: formidable, slower ships intended as battle-line bulwarks.
