Abstract: A projectile launch opening is submersed in water, a projectile ejector ejects the projectile from the projectile launch opening, and a gaseous cavity ejector ejects a gas to form a gaseous launch cavity covering the launch opening, synchronized with the projectile ejection, such that a leading surface of the projectile initially impacts the water at an inner surface of the gaseous launch cavity spaced above the launch opening, at an impact velocity initiating a supercavitation, the supercavitation substantially encapsulating the entire projectile within the water.
