It is based on technology insertion and use of commercial products, processes, and practices to extend a system's useful life. Both the CTR spares and the current inventory spares must be capable of being used interchangeability with the interfacing components and equipment.
Developmental testing is required.
CTR is a procurement strategy. It is not funded separately but rather it takes advantage of other funded programs. Such efforts must result in a physical hardware application for spares using existing technology. SMA-OSCR does not fund efforts to increase performance. Performance enhancements are only permitted as a by-product of the cost reduction design change.
