A Swedish Baltic force built around large destroyers

What could Sweden build in 1923 to make treaty powers take notice?

Fast, heavily armed large destroyers with strong torpedo and anti-aircraft batteries would fit Baltic conditions, backed by submarines and a few powerful flotilla leaders.

The proposed force uses 3,000-ton destroyers as fast light-cruiser-like ships suited to the Baltic's confined waters. Five-inch guns, numerous Swedish 40 mm weapons, and heavy torpedo batteries would let packs threaten much larger intruders. Submarines would add another layer to the local denial force. A few fast 18,000-ton ships with 9.2-inch guns and long range would act as flotilla leaders and diplomatic cruisers, forcing treaty navies to respond with capital ships.
