Prinz Eugen was a German heavy cruiser that served during the Second World War, and its name has since become familiar to many players through naval games and historical documentaries. This particular clip circulates online as a standalone naval gunfire sound rather than a documented recording from the ship itself, which is why creators treat it as a general war sound effect. Its staying power comes from that flexibility: the boom is instantly recognisable as heavy artillery, so it works across history edits, gaming videos and dramatic memes without needing any explanation.
