Two Swedish yards built the cruisers in parallel

The cruisers were not serial products from one constrained yard because Sweden possessed two facilities capable of building them in parallel. Götaverken traced its origins to Alexander Keiller's 1841 enterprise and survived bankruptcy through reorganization and expanded capacity. During the 1930s it became the world's largest shipyard by launched gross registered tonnage, then developed a new largely indoor yard at Arendal after the war. That scale explains how a relatively small neutral state could undertake major-warship construction without relying on a single industrial bottleneck.
