This test case is based on the Sea Systems Template 881C structure, weight distributions, and manufacturing complexities. All hardware objects are scaled to the weight of Legend NSC. No changes are made to the software objects of the template. This example uses schedule dates of the Legend program. No attempt has been made to simulate the Legend’s design heritage or quantities of spares, prototypes, and production units. Therefore, this example should be viewed as an illustration of how the sea system template can be used to produce a rough cost estimate of a known naval program.
