The objective of this effort is to determine Seawolf FTP maintenance requirements and outline a plan of action. A concurrent engineering approach is used to determine these requirements via assessing FTP test and maintenance requirements across all levels of test and design verification, factory test and depot maintenance test. From a total life cycle perspective, feasibility of Navy organic support is analyzed at the assembly and Ship Control Processing Unit and FTP channel electronics and line replaceable unit levels of system indenture. A common hardware and software approach for supporting all levels of FTP test and maintenance is investigated for feasibility. This innovative approach uses commercial off-the-shelf VXI instrumentation modules, presentation manager software and a model-based diagnostic reasoning run-time software system. The proposed approach for effecting total life cycle support is innovative because a common hierarchical diagnostic model of the FTP will be used on the same test system architecture to support all the possible levels of FTP test and repair.
