The paper discusses the fundamental problem of high-speed motion of supercavitating bodies in water — inertial and jet bodies with a compact pulse jet engine, and their impact on underwater barriers as well. A study on modes of motion of unreactive supercavitating projectiles with running compact pulse jet engine with sub-, trans- and supersonic speeds in water medium after speeding-up in the barrelled accelerator is done with calculation-experimental method. Velocity gain of projectile motion by virtue of using а compact pulse jet engine is estimated. Nature of interaction of projectiles with underwater barriers including those containing an explosive is studied.
