This test case is based on the C4ISR Electronic System Template 881C structure, weight distributions, and manufacturing complexities. All hardware objects are scaled to the weight of FBCB2/BFT. No changes are made to the software objects of the template. This example uses schedule dates and quantities of the FBCB2/BFT program. No attempt has been made to differentiate among the various models of the FBCB2/BFT nor has any attempt been made to simulate the mutilple production lots of the program. Therefore, this example should be viewed as an illustration of how the C4ISR electronic system template can be used to produce a rough cost estimate of a known C4ISR program.
