The samples on the basis of carbide and tungsten alloy were made by means of high-temperature sintering. The samples possess a perfect brand-new complex of physical, mechanical and functional properties. Penetrating ability of the samples concerning going through a steel obstacle with the interaction velocity of 1300 m/s is investigated. The comparison is made with the sample made of a basic alloy VNZH-90

The analysis of supercavities formed during the high-speed motion in water of two closely spaced supercavitating strikers is performed. By comparing of geometric characteristics of supercavities, the possibility of qualitative assessment of the degree of influence of closely spaced strikers is shown. By the example of two strikers, the characteristic distance between them was determined, at which the minimum mutual influence of the strikers on each other is observed.
