The Scharnhorst class shows why gun caliber can reflect industrial availability rather than a ship's intended tactical category. Germany could fit available 11-inch guns immediately or leave hulls idle while waiting for a 15-inch program. Japan faced a related constraint when treaty limits and the Yamato program delayed replacement of the aging Kongos. Modernization kept those ships useful, but unsuitable for many one-on-one capital-ship engagements. Mikawa instead preferred to employ them in a coordinated task force that could control range, divide an opponent's attention, and concentrate several ships against one target.

Industrial capacity complicates capital-ship labels
Gun size may reflect the weapons an industry can deliver rather than the role designers intended, while older ships can survive by fighting as part of a coordinated force.
