A reassessment of naval vehicle performance leads to the definition of specific energy as a significant measure of vehicle performance. Specific energy is an energy efficiency equal to the product of transport efficiency and Froude number. In terms of specific energy, the empirical performance data for fluidborne vehicles collapse revealing systematic trends with Froude number for fully-immersed buoyant vehicles, surface ships, and dynamic-lift vehicles. Specific energy appears to be a new consistent basis for comparing the overall technical performance of past, present and future naval vehicles.
