UTILITY SYSTEMS DESIGN REQUIREMENTS FOR COMMAND, CONTROL, COMMUNICATIONS, COMPUTER, INTELLIGENCE, SURVEILLANCE, AND RECONNAISSANCE (C4ISR) FACILITIES
|Publication Date:||27 December 2006|
This manual shall be used in the engineering design, fabrication, and installation of specifically designated fixed ground-based facilities in a threat-hardened C4ISR network. Minimum performance requirements are prescribed for the design of highly reliable utility systems that will permit C4ISR operation free from man-made threats. This manual applies to both new construction and to retrofit of existing facilities. Use of the manual for threat protection of other ground-based communicationselectr
a. First is a small C4ISR facility such as a remote telephone switch center, typically housed in a building of less than 1000 square feet of floor area. The power system requirements will be less than 250 kVA.
b. Second is an average C4ISR facility such as a main computer/communicati
c. Third is a C4ISR complex that consists of several buildings and a central distribution power plant. The power system requirements will generally be on the order of ten MVA or greater.
This manual establishes minimum requirements and design objectives for utility systems supporting major fixed Command, Control, Communications, Computer, Intelligence, Surveillance, and Reconnaissance (C4ISR) facilities. The existence of the manual does not, in itself, authorize upgrade or modifications of existing C4ISR facilities solely to meet these requirements. Facilities required to fully comply with the provisions of the manual will be designated by the Joint Chiefs of Staff, a Military Department Headquarters, or a Major Command.
