This essay is focused on naval vessels as its main research aspect. It tries to find out in that area possible methods and strategies of applying knowledge management by probing into certain naval vessels for thorough comprehension of the knowledge content and ongoing ways of knowledge management needed for daily operations of each ship as a single case. In addition to the information obtained from ROC navy vessels concerning the problems and difficulties they are encountering when dealing with knowledge management, opinions consulted from experts and relative publications are combined to give suggestions of applicable knowledge management modes and strategies for the future. It is our expectation that through this research a reliable operation framework can be set up so as to keep, accumulate, transfer, and even create professional knowledge for our navy. It is our hope that the framework together with the modes and strategies will help to build up an intact system for knowledge management so as to render the utmost combat capability to our second-generation naval forces.
