... Semi-submersible vehicles have low-profile platforms above the water surface while keeping most of their hulls below waterline. In addition to reduced detectability, these craft may potentially have good seaworthiness and hydrodynamic advantage at fast displacement speeds. In this study...

... This paper covers the numerical and experimental evaluation including vehicle resistance and self-propulsion performance, waterjet flow rate, and running attitude changes of an amphibious tracked vehicle. A reduced-scale model of the waterjet propelled amphibious tracked vehicle was designed...

Propulsion systems based on MHD require virtually no mechanical components; therefore, a good application would be to design a propulsor which produces very little noise for small underwater vehicles. Results of a preliminary feasibility study on this application are presented in this paper...
