OSCAM JSF is a version of OSCAM that was specifically designed for the Joint Strike Fighter (F-35) program. The OSCAM JSF model is an Operating and Support (O&S) costing tool, available to JSF partner countries to assist them in developing CAIG based O&S cost estimates. The tool is a way of sharing data with partners and a way for partners to understand life cycle O&S cost analysis.

Note: The OSCAM JSF model is not currently being maintained or updated. Please reach out to the OSCAM Program Management team for more information.


The simulation is controlled via a powerful user interface that allows selection and editing of data, running the simulation, analysis of results and a number of analysis tools, including risk analysis. The business processes are documented through interactive influence diagrams that are accessible via every input and output in the model. These diagrams ensure that OSCAM is not a black box and enables understanding and confidence in the outputs generated by the model.

OSCAM JSF is designed to be flexible, so that it can be used to represent a wide range of scenarios for different partner countries. OSCAM JSF also provides a number of choices on the level of detail that is required to populate a data record. This allows OSCAM to be used early on in the development process and then to grow as the program matures to include a more detailed representation of the program with enhanced model input flexibility.

Partner countries can make use of the datasets provided by the F-35 JPO to generate baseline cost estimates and make changes to input values to see the estimates for alternative scenarios. OSCAM contains powerful analysis tools to investigate the differences between estimates and to perform uncertainty analysis around input values. OSCAM JSF v2 specifies all inputs and outputs in US$, but the OSCAM JSF Post Analysis Tool allows outputs to be converted to other currencies using fixed or annualized exchange rates, and allows the definition of inflation categories for calculating annual cash outputs.
