This test case is based on the Unmanned Maritime Vehicle Systems 881C structure, weight distributions, and manufacturing complexities. All hardware objects are scaled to the weight of the Sea Hunter UMV. No changes are made to the software objects of the template. This example uses schedule dates of the Sea Hunter program. No attempt has been made to simulate the Sea Hunter design heritage or quantities of spares, prototypes, and production units. Therefore, this example should be viewed as an illustration of how the unmanned maritime vehicle systems template can be used to produce a rough cost estimate of a known UMV program.
