The technology of waterjet propulsion has reached a state of development where discussion of all technical aspects is beyond the scope and intent of this paper. The utilization and expansion of liquid rocket engine pump technologies derived from the U.S. military and space programs will be described, design of a single-stage axial flow pump for a new fast passenger hydrofoil will be discussed, and key benefits and features of waterjet systems will be discussed throughout the paper. The paper concludes with a forecast of possible uses for waterjet systems.
