A torpedo "in the tube" and ready to be launched.
The only thing necessary for it to launch is the launch directive.
The first warshot "bouncing bombs" were used in combat by the Royal Air Force's 617 Squadron in an attack on the Möhne and Eder dams in the Ruhr region of Germany. They were designed to bounce over the anti-torpedo netting protecting these dams, allowing for the bomb to be released similarly to a torpedo, minimising detection and ensuring a high degree of accuracy.
