A major problem exists in the development of current state-of-the-art weapons system trainers in the quality of the software provided. Since the software for a given trainer is typically generated on the deliverable computer system for the trainer a wide variance in the tools available to support the design and development of the software exists from project to project.

The specification requirement of a high order language (FORTRAN) has led to the evolution of software development facilities at various simulator manufacturers. While these have immediate impact in reducing the cost of the software produced and aid in maintaining schedule on the ongoing programs, their most significant impact is that the software delivered using them is significantly improved.

The paper explains what was experienced when the SDF concept was applied to some current contracts.
