MIL-STD-188 Totally Explained

Everything about Mil-std-188 totally explained

MIL-STD-188 is a series of U.S. military standards relating to telecommunications.

Purpose

Faced with “past technical deficiencies in telecommunications systems and equipment and software…that were traced to basic inadequacies in the application of telecommunication standards and to the lack of a well defined…program for their review, control and implementation”, the U.S. Department of Defense looked to develop a series of standards that would alleviate the problem.
By 1988, the U.S. Department of Defense (DoD) issued Instruction 4630.8 (reissued in 1992, 2002, 2004) stating its policy that “all forces for joint and combined operations be supported through compatible, interoperable, and integrated Command, Control, Communications, and Intelligence systems. …[andthat all such] systems developed for use by U.S. forces are considered to be for joint use.” To achieve this the director of the Defense Information Systems Agency (DISA) is charged with “developing information technology standards to achieve interoperability and compatibility…[andinsure that all] systems and equipment shall conform to technical and procedural standards for interface, interoperability, and compatibility”. The Defense Information Systems Agency published circulars which announced both standards and engineering criteria relating to the long-haul Defense Communications System and to the technical support of the Worldwide Military Command and Control System.

Deviations and waivers

For any manufacturer seeking to deviate from the MIL–STD-188 series standards (prior to the manufacture of an item) they must request to do so with the Joint Steering Committee (JSC) which is constituted under the Defense Communications Agency. For any DoD Agency to get a waiver to receive an item that deviates from the standards they also must apply to the JSC.

Relation to other systems of standards

According to DoD documents, “The MIL-STD-188 series may be based on, or make reference to, Joint Technical Architecture, American National Standards Institute (ANSI) standards, International Telecommunications Union - Telecommunication Standardization Sector (ITU-T) recommendations, North Atlantic Treaty Organization (NATO) Standardization Agreements (STANAG), and other standards wherever applicable.”

Current development emphasis

Currently the DoD is placing its emphasis “on the development of common standards for tactical and long-haul communications (the MIL-STD-188-100 series).”
