According to the typical missions of underwater unmanned combat platform，this paper analyzes and determines the operational test indexes of operational effectiveness，operational applicability and system applicability of underwater unmanned combat platforms . On the basis of the basic operational process of underwater unmanned combat platform operational tests，the mission profile and the operational test process of underwater unmanned combat platform are constructed. It provides the support for the formation of test subjects，the formation of test samples by the means of test design and the determination of operational test implementation process for the underwater unmanned combat platform.
