Exploratory development for lightweight torpedo propulsion has continued through the years to support development of electric, open-cycle thermal systems. Several systems representative of these propulsion types are being pursued both by Naval Laboratories and by industry which are potential candidates for a new generation of lightweight torpedoes. Four of the most promising systems are discussed: An improved open-cycle monopropellant propulsion system; a closed-cycle system, known as the Stored Chemical Energy Propulsion System (SCEPS); and two battery-electric propulsion systems. One of the battery systems is somewhat reminiscent of the older seawater battery system, but has far superior energhy densities. The second battery system is completely closed and has the potential of being very simple, also with very high energy density. Advantages and disadvantages of the four systems are discussed, followed by discussions of the energy sources, prime movers, speed reducers, and systems considerations. Background information on the seawater battery electric and earlier open-cycle systems is also included. (Author)
