FOREWORD

1. This standard is approved for use by all Departments and Agencies of the Department of Defense (DoD) within the distribution limitations noted at the bottom of the cover.

2. It is DoD policy that all joint and combined operations be supported by compatible;

interoperable; and integrated Command, Control, Communications, and Intelligence (C3I) systems. All C3I systems developed for use by U.S. forces are considered to be for joint use.

The Director, Defense Information Systems Agency (DISA), serves as the DoD single point of contact for developing information technology standards to achieve interoperability and compatibility. All C3I systems and equipment shall conform to technical and procedural standards for compatibility and interoperability.

3. Military Standards (MIL-STDs) in the 188 series (MIL-STD-188-XXX) address telecommunications design parameters and are to be used in all new DoD systems and equipment procurements, or major upgrades thereto. The MIL-STD-188 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. Emphasis is being placed on the development of common standards for tactical and long-haul communications (the

MIL-STD-188-100 series). The MIL-STD-188 series may be based on, or make reference to, American National Standards Institute (ANSI) standards, International Telecommunications

Union – Telecommunication (ITU-T) Standardization Sector recommendations, International

Standards Organization (ISO), North Atlantic Treaty Organization (NATO) Standardization

Agreements (STANAGs), and other standards, wherever applicable.

4. This MIL-STD is part of a profile of standards for Super High Frequency (SHF)

Satellite Communications (SATCOM) (6.5).

5. Comments, suggestions, and questions on this document should be addressed to

DISA, 6910 Cooper Ave., ATTN: IE53, Fort Meade, MD 20755-5496, or emailed to henry.h.tran.civ@mail.mil. Because contact information can change, verify the currency of this address information by using the ASSIST Online database at https://assist.dla.mil.
