Exactly how widespread and common was re-purposing ships?


Hey Indy and team. I’ve been reading up on some of the navies of the war and noticed that Japan had a tendency to re-purpose vessels rather drastically from their intended use. The aircraft carriers Taiyo and Shin’yo (formerly the Japanese passenger liner Kasuga Maru and the German passenger liner Scharnhorst) and the aircraft carrier Kaga (what was built out of the hull of a Tosa class battleship) and Akagi (a re-purposed Amagi class battlecruiser) come to mind. While this does make sense in the context of Japans resource scarcity and the Washington Naval Treaty, did any of the other powers re-purpose ships like this? Not necessarily as aircraft carriers, just different to what they were originally built for.
