Revolver mechanisms for rapid-fire naval guns

Did anyone ever arrange a naval gun like a revolver to increase its rate of fire?

Yes, mainly for small-calibre experiments, but the mechanism proved impractical and saw little development.

Armstrong Whitworth and American firms experimented with naval guns arranged on revolver-like principles. The concept sought rapid fire by cycling chambers or barrels rather than loading one conventional breech repeatedly. It was attempted chiefly on small weapons around 1.5 to 1.9 inches, where ammunition remained manageable. The mechanisms did not develop far, which indicates that complexity and scaling costs outweighed their early rate-of-fire promise.
