With the change of the international strategy form, the marine conflict mode is quietly evolving towards diversified directions, and frogman fighting becomes a novel fighting means. Upgrading of frogman gear is also a focus of research in various countries, where the re-rise of small frogman propulsion Devices (DPVs) is particularly attractive. Various DPV products for military use and civil use are successively provided by companies of various countries, and the DPV is not only suitable for special operations of navy, but also widely applied to the aspects of diving entertainment, underwater photography and the like. The MK series of Farallon company in the United states is DPV with the most advanced and commercialized technology in the market at present, 6061-T6 aluminum material is adopted, the weight is greatly reduced, and a specially designed circuit board can realize the function of stepless speed change. In addition, military circuit boards are also provided with spare boards and placed in individual units, which ensure proper operation even if sealing problems occur. The Protei-5 type DPV used by the Russian navy has a length of about 1.75m and a width of 0.66m, and the shell is made of titanium alloy and is powered by six seamless lead-acid batteries. It has the advantages of high speed, long range, easy operation, etc. but has no speed regulating function.
