Welcome to the PROS IV Website

The Parts and Repair Ordering System (PROS) procurement system is managed by the Air Force Security Assistance Center (AFSAC) to support Foreign Military Sales (FMS) customers' logistics requirements. In the 5th generation of PROS (PROS IV), the program has expanded to a tri-service effort supporting FMS customers through procurement and maintenance support for a wide range of nonstandard and hard to support standard items as well as providing a contracting vehicle for specialized engineering and technical services through task orders.
