Technical improvement versus fleet standardization

All four German capital ships received Seetakt radar and hydrophones, but not necessarily the same versions. The variations suggest a persistent reluctance to standardize equipment even between sister ships. A locally improved component could still make fleet maintenance harder by multiplying spares, procedures, and specialist knowledge. Those burdens were especially costly in a fleet containing only four modern capital ships, where there was little scale to absorb unique parts or training. Fleet-wide supportability could matter more than a marginal technical improvement aboard one hull.
