Subdivision and slow-speed handling made Black Swans durable hunters

The internal view of a Black Swan reveals a highly subdivided structure despite the ship's compact size. That arrangement created reserve survival space and room for machinery, helping explain both robustness and power within a small hull. Sloops were also particularly good at slow-speed work, an important quality during anti-submarine operations. Later throwers and other systems could be installed without fighting a hull that had been optimized around one immutable fit. The combination made the ships durable, manageable at low speed, and easier to update with new anti-submarine weapons.
