Enhanced cavitation in which large continuous cavities are formed behind an object moving rapidly through a liquid.Supercavitation acts to reduce the drag on a moving object. Devices such as propellers and high-speed torpedoes can be designed to exploit this.

1944 V. L. Posdunine in Trans. Inst. Nav. Archit. 86 138/1 The phenomenon of supercavitation opens wide prospects in marine propeller design.
1961 New Scientist 31 Aug. 528 Super-cavitation foils and propellers are actually designed to exploit the cavitation condition.
2008 D. Poyer Weapon iii. 29 Supercavitation, Pirrell said, was deliberate sustained cavitation along the length of a moving vehicle, harnessing a phenomenon that up to now had been a nuisance.
