The “Jericho trumpet” refers to the distinctive, wailing siren used by German Stuka dive bombers (Junkers Ju 87) during World War II. Named after the biblical story of Jericho’s walls falling from the sound of trumpets, this siren was mounted on the aircraft’s landing gear and activated during dives. The eerie, terrifying sound was designed to instill fear in enemy troops and civilians, making psychological warfare a component of air raids. The siren amplified the Stuka’s intimidating reputation
