Question

Were the Kongō-class ships battleships rather than battlecruisers?

Short answer

They were battlecruisers until their 1930s reconstruction turned them into comparatively poor but genuine fast battleships.

Notes

The answer resists applying a ship's final classification backward across its entire service life. The Kongōs began as battlecruisers and remained so through much of the interwar period. Their extensive 1930s reconstructions increased protection and displaced enough weight to support reclassification as fast battleships. This makes classification a function of configuration and date, not merely a permanent label attached at launch.
