How would a submarine-heavy German navy before World War I change other navies' development?
Short answerRivals would invest in anti-submarine forces, while contemporary technology would limit what Germany's specialization could achieve against a balanced response.
NotesOther navies would respond directly by building anti-submarine capabilities rather than passively accepting a German advantage. The closest comparison is an artillery-heavy army. Concentration can be formidable, but it also makes the force's imbalance obvious. Opponents can then develop forces and tactics that exploit what the specialist formation lacks.
