OSCAM USAF was developed for the USAF C-17 SPO. Other organisations involved in the development were the F-22 Program Office and the Aeronautical Systems Center Cost Analysis Staff. The model currently stands at version 1.0.

The model was developed, using existing versions of OSCAM, to meet specific C-17 SPO requirements, yet remains generic enough to be useful to other USAF programs.

A Data Management Tool(DMT) for OSCAM USAF has also been developed, enabling maintainance philosophies to be applied to component level data within a work breakdown structure prior to simulation.

In addition, the OSCAM USAF model has undergone a rigorous verification and validation process in order to build confidence that it can be trusted when used properly with valid input data.

OSCAM USAF has been used for life cycle O&S cost estimates to evaluate contractor and organic support concepts. Other uses of the model include O&S tradeoff analyses, R-TOC tradeoff studies and initiative evaluations and the evaluation of future upgrades/modifications.
