For many years, the U.S. Department of Defense has stressed the need for COTS (Commercial Of The Shelf) products wherever possible to reduce the cost of military systems. This approach while acceptable for many non-critical support applications, many military systems are required to have high reliability while being subject to harsh environments found in shipboard, airborne, and ground mobile military applications. While standard COTS products may appear to be satisfactory on paper, they may not meet the longevity and rugged performance requirements most Military customers demand. Because of this, ROTS (Rugged Off The Shelf) products may be the correct approach.
