R&D Strategy of Next Generation Electric Power Lightweight Torpedo in US Navy

Electrically powered torpedo has many advantages,such as low training cost,low noise,stealth,modularized battery and high reliability.Therefore,US Navy has begun to develop new generation of electrically powered lightweight torpedo in recent years,and some breakthrough has been achieved on the integrated motor propulsor (IMP)of electrically powered torpedo.This paper describes the research background and status quo of the torpedo,and analyses the advantages of IMP.On analyzing the research and development (R&D) strategy of the electrically powered lightweight torpedo in US Navy,it is suggested that different power technology should be traced and developed appropriately to keep continual competitive ability,operational adaptability and training cost of new weapon should be emphasized to enhance comprehensive benefit,R&D of weapon technology should be planned from the viewpoint of underwater equipment system,and universality of technology and product should be paid more attention.
