Why might HMS Ark Royal's bow have separated as she sank?
Short answerExisting damage, trapped air, uneven flooding, and pressure changes could combine into structural failure during the descent.
NotesNo final diagnosis is possible without a detailed study of the wreck report. One qualified explanation combines an air pocket in one section, flooding elsewhere, and changing external pressure. Those forces could load an already damaged structure unevenly until it separated. Wreck interpretation must account for both combat damage and what happens after a ship leaves the surface.
