The scenario imagines diesel propulsion reaching both the Type 1934 and Type 1936 destroyer groups. Greater endurance would give those ships more options during the opening of the war and the Norwegian operations of 1940. Diesel torpedo boats extend the same proposal to smaller surface forces. The precise destroyer range quoted here is unclear, so the argument establishes an intended endurance benefit rather than a specific performance figure.

Diesel destroyers for the opening campaigns
Earlier diesel machinery would widen the uses of German destroyers in 1939 and during the Norwegian campaign.
