Future military needs in propulsion systems for surfaces vehicles are examined in order to provide guidance for Technology Base programs directed at improved engines, transmissions, thrusters and fuels. It is observed that there is a physical tendency for power-generating systems to grow heavier per horsepower as output increases. This trend runs counter to the requirements of more mobile vehicles which need more power for less weight. These effects are quantified and it is shown that the performance demands of many projected military surface vehicles severely restrict the propulsion system options that technology can provide.
