This test case is based on the Guided Bomb Ordnance Systems 881C structure, weight distributions, and manufacturing complexities. All hardware objects are scaled to the weight of GBU-31. No changes are made to the software objects of the template. This example uses schedule dates of the GBU-31 program. No attempt has been made to simulate the GBU-31 design heritage or quantities of spares, prototypes, and production units. Therefore, this example should be viewed as an illustration of how the guided bomb ordnance systems template can be used to produce a rough cost estimate of a known ordnance program.
