Why the Constitution class was not wholly revolutionary

Why do some American historians call Constitution and her sisters revolutionary when comparable leaders, razees, and 32-pounder frigates existed?

National narratives emphasize the famous American ships while often leaving out earlier foreign designs that weaken the claim of uniqueness.

Claims of a uniquely revolutionary Constitution class are treated as patriotic framing rather than a complete comparison. Their size and success were notable, but contemporary discussion can overlook earlier 32-pounder ships and razees that complicate the exceptionalist story.
