A high-speed vehicle or device presents a surface configured to move through a fluid such that the fluid flows across the surface in a primary flow direction. The vehicle or device also presents a subsurface spaced inwardly from the surface, as well as a plurality of cavity-defining structures that project generally outwardly from the subsurface and extend along the subsurface generally transverse to the primary flow direction. The cavity-defining structures are spaced apart in the primary flow direction. Each adjacent pair of the cavity-defining structures and the subsurface at least in part cooperatively define a cavity therebetween. Fluid rollers or vortices are formed in the cavities, with frictional forces thereby being generated therein in a direction opposite of drag forces on the surface. Each of the cavity-defining structures defines at least one interconnecting channel extending between adjacent ones of the cavities to fluid interconnect said cavities.
