Germany repeatedly changed designs instead of producing large homogeneous classes. Scharnhorst, Bismarck, and successive H-class pairs would not share enough machinery, weapons, or operating characteristics to behave like interchangeable units. Even if all planned hulls were completed, only a fraction would be ready, while obsolescent cruisers would add little credible combat power by 1948. Variety therefore reduced the operational value hidden behind the program's headline numbers.

Small, varied classes magnified the readiness burden
Plan Z's many small and dissimilar classes would each impose separate training, maintenance, and logistics demands.
