High-speed vehicles launched by surface or aerial platforms break the speed limit of traditional underwater weapons with the help of supercavity drag reduction technology and can effectively intercept and attack potential underwater threats with the advantage of high speed. This has become a hotspot of research worldwide. However, problems such as complex multiphase turbulence flow, unsteady evolution of the supercavity, and water entry impact load during the water-entry process of transmedium vehicles restrict the stable navigation of the supercavity vehicle and affect operational effectiveness. In this paper, from the aspects of unsteady supercavity flow patterns, trans-medium impact loads, and tail slaps of high-speed vehicles, the technical difficulties of stable water entry for trans-medium vehicles are summarized, the methods of load reduction for high-speed vehicles during the water-entry process are summarized, and the engineering applications of trans-medium supercavitating vehicles are summarized. Finally, the problems to be solved and future development tendencies of trans-medium vehicles are discussed.
