2、N FOR FIXED GROUND-BASED C I FACILITIES PERFORMING CRITICAL,4TIME-URGENT MISSIONSF O R E W O R D1. This military standard is approved for use by all Departments and Agencies of theDepartment of Defense (DoD). 2. Originally, Military Standard 188 (MIL-STD-188) covered technical standards for tactical

3、and long-haul communications, but later evolved through revisions (MIL-STD-188A, MIL-STD-188B) into a document applicable to tactical communications only (MIL-STD-188C).3. The Defense Information Systems Agency (DISA) published DISA circulars (DISAC)promulgating standards and engineering criteria ap

4、plicable to the long-haul DefenseCommunication System and to the technical support of the National Military CommandSystem.4. As a result of a Joint Chiefs of Staff action, standards for all military communications arenow being published in a MIL-STD-188 series of documents. The MIL-STD-188 series is

5、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 tacticalcommunications only; and a MIL-STD-188-300 series, covering standards for long-haulcommunications only. Emphasis is being placed on

6、developing common standards for tacticaland long-haul communications published in the MIL-STD-188-100 series.5. This two-part document contains technical requirements and design objectives for high-altitude electromagnetic pulse (HEMP) protection of ground-based systems and facilities thatare nodes

7、in HEMP-hardened networks for performing critical and time-urgent command,control, communications, computer, and intelligence (C I) missions. This part 1 of the4document addresses HEMP hardening for fixed facilities; Part 2 addresses transportablesystems. The requirements are stringent, in order to

8、avoid both damage and functional upsetsthat prevent mission accomplishment within operationally prescribed timelines. The standardsapply uniformly to all systems and facilities in the end-to-end chain, since disruption of asingle node may result in network failure.6. Use of the standard for HEMP pro

9、tection of other fixed ground-based communications-electronics facilities that require HEMP hardening is encouraged to the extent permitted bycost constraints.Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-STD-188-125-1iii7.

43、IL-STD-188-125-1This part of the standard addresses fixed facilities only. A fixed ground-based facility, for purposes of this1standard, consists of equipment in a permanent building or shelter that provides survivable C I capabilities at a fixed4geographical location. HEMP hardening measures for tr

44、ansportable systems are contained in MIL-STD-188-125-2.11. SCOPE1.1 Purpose. This standard establishes minimum requirements and design objectivesfor high-altitude electromagnetic pulse (HEMP) hardening of fixed ground-based facilities1that perform critical, time-urgent command, control, communicatio

45、ns, computer, andintelligence (C I) missions. Facilities required to fully comply with the provisions of the4standard will be designated by the Joint Chiefs of Staff, a Military Department Headquarters,or a Major Command.1.2 Scope. This standard prescribes minimum performance requirements for low-ri

46、skprotection from mission-aborting damage or upset due to HEMP threat environments definedin MIL-STD-2169. This standard also addresses minimum testing requirements fordemonstrating that prescribed performance has been achieved and for verifying that theinstalled protection subsystem provides the op

47、erationally required hardness for the completedfacility. If the prescribed testing results in any hardware damage or functional upsets, theoperational authority for the facility will make the determination whether the observed event ismission aborting.1.3 Applications. This standard defines the desi

48、gn and testing criteria for specificallydesignated fixed ground-based facilities in HEMP-hardened, critical, time-urgent C I4networks. Such nodes include subscriber terminals and data processing centers, transmittingand receiving communications stations, and relay facilities. The standard applies to

49、 both newconstruction and retrofit of existing facilities. Although only local portions of facilityinterconnects are addressed, it is assumed that survivable long-haul communications paths,fiber optic links, or other hardened interconnects between facilities will be provided asrequired for mission accomplishment.
