Since 1969 the services have been required to develop their preferred programs within a fiscal constraint set by the Secretary of Defense. Todays Navy planner chooses force levels, major procurement programs, and ship and aircraft operating policies constrained by the fixed budget, he achieves increases in one area only by giving up resources in another. It became desirable to have an automated technique that would rapidly and consistently determine the resources needed for the many broad choices open to Navy decision- makers within fiscal guidance. The Center for Naval Analyses developed the Navy Resource Model NARM for this purpose. Given data that describes a base year, and a force structure of ships and aircraft that is desired in future years, it will develop a consistent program for those years.
