 (DISA) is charged with “developing information technology standards to achieve interoperability and compatibility…[and insure that all] systems and equipment shall conform to technical and procedural standards for interface, interoperability, and compatibility”.

The MIL-STD-188 standards were created to “address telecommunication design parameters based on proven technologies.” To ensure interoperability, DISA made these standards mandatory for use in all new DoD systems and equipment, or major upgrades.

“The mandatory use of these standards will aid significantly in achieving standardization and result in improvements in availability, maintainability, reliability, and supportability. This, in turn, will enhance lifecycle configuration management and logistic support with subsequent reductions in life cycle costs.”


Evolution

When first developed Military Standard 188 (MIL-STD-188) covered technical standards for tactical and long-haul communications
Long-haul communications

In telecommunication, the term long-haul communications has the following meanings:1. In public switched networks, pertaining to circuits that span large distances, such as the circuits in Interexchange carrier, interstate, and international telecommunication....
, but as it was revised (MIL-STD-188A, MIL-STD-188B) it became a document applicable to tactical communications
Tactical communications

Tactical communications are communications in which information of any kind, especially orders and decisions, are conveyed from one command, person, or place to another within the tactical forces....

, these standards are published in the MIL-STD-188 series of documents. This series is subdivided into "a MIL-STD-188-100 series covering common standards for tactical and long-haul communications, a MIL-STD-188-200 series covering standards for tactical communications only, and a MIL-STD-188-300 series covering standards for long-haul communications only."

The MIL-STD-188 series standards are encompassed by the DoD’s Joint Technical Architecture.

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).”
