MIL-STD-188-125 Training
MIL-STD-188-125 Training is a 2-day technical training course covers High Altitude Electromagnetic Pulse ( HEMP / EMP ) protection.
High Altitude Electromagnetic Pulse ( HEMP / EMP ) protection is a widespread concern. A small nuclear device, “accidentally” detonated high in space, can produce a pulse of electromagnetic energy that cripples computers and communication systems below it, while at the same time causing no injuries or visible destruction.
Participants will learn about concerns on High Altitude Electromagnetic Pulse ( HEMP ) protection used in the design of mission-critical facilities.
MIL-STD-188-125 Training course covers the key concepts and terminology of High Altitude Electromagnetic Pulse ( HEMP ) protection used in military and civilian practices. The course also provides practical aspects on ways to install, manage, and maintain HIGH ALTITUDE ELECTROMAGNETIC PULSE ( HEMP ) protection.
This course covers the High Altitude Electromagnetic Pulse ( HEMP ) awareness training requirements of the following Department of Defense standards:
- MIL-STD-188-125-1 : ” HIGH ALTITUDE ELECTROMAGNETIC PULSE ( HEMP ) PROTECTION FOR GROUND-BASED C4I FACILITIES PERFORMING CRITICAL, TIME URGENT MISSIONS PART 1 FIXED FACILITIES “
- MIL-STD-188-125-2 : ” HIGH ALTITUDE ELECTROMAGNETIC PULSE ( HEMP ) PROTECTION FOR GROUND-BASED C4I FACILITIES PERFORMING CRITICAL, TIME URGENT MISSIONS PART 2 TRANSPORTABLE SYSTEMS “
Participants will learn about key aspects on MIL-STD 188-125-1 to evaluate low-risk protection from mission-aborting damage due to HEMP attacks along with requirements to demonstrate that prescribed performance has been achieved. MIL-STD 188-125 verifies that the installed protection subsystem provides the operationally required hardness for the completed facility.
The MIL-STD-188-125-1 test standard defines the design and testing criteria. Specifically designated for fixed ground-based facilities in HEMP-hardened, critical, time-urgent C4I networks. Facilities include subscriber terminals and data processing centers, transmitting and receiving communications stations, and relay facilities. MIL-STD-188-125-1 applies to both new construction and the retrofit of existing facilities.
Scope of the Military Standard Test Method 188-125-1
- To gain a better understanding of the requirements in HEMP testing.
- Electromagnetic stress is a voltage, current, charge, or electromagnetic field that acts on a piece of equipment. If the electromagnetic stress exceeds the vulnerability threshold of the equipment, mission-aborting damage or upset may occur.
- Facility HEMP shield is the continuous conductive housing that substantially reduces the coupling of HEMP electric and magnetic fields into the protected volume. The facility HEMP shield is part of the electromagnetic barrier.
- HEMP hardness surveillance/re-verification testing is testing conducted at prescribed intervals during the operational phase of the facility life cycle. This testing is for evaluating whether the HEMP protection measures continue to provide the required HEMP hardness. HS/re-verification test requirements are established in the technical manual.
- A main barrier electrical POE protective device is a protective device installed on an electrical conductor that penetrates from the system exterior, through the HEMP shield, and into the protected volume. Main barrier protective devices must meet the performance requirements of this standard.
- A special protective volume is a HEMP-protected space within the facility, where electromagnetic stresses due to HEMP may exceed the residual internal stress limits for the protected volume. The special protective barrier may be a separate shield with protected penetrations. These are more commonly, shielded cables or conduits, and equipment cabinets and closed piping systems are used to provide the needed electromagnetic isolation from the protected volume.
- The vulnerability threshold (of an equipment) is the minimum stress level that causes the equipment to suffer definite damage or performance degradation. In the context of this standard, the vulnerability threshold is the minimum electromagnetic stress that causes mission-aborting damage or upset.
MIL-STD-188-125-2 establishes minimum requirements and design objectives for high-altitude electromagnetic pulse (HEMP) hardening of transportable ground-based systems that perform critical, time-urgent command, control, communications, computer, and intelligence (C4I) missions.
MIL-STD-188-125-2 prescribes minimum performance requirements for low-risk protection from mission-aborting damage or upset due to HEMP threat environments defined in MIL-STD-2169. The standard also addresses minimum testing requirements for demonstrating that prescribed performance has been achieved and for verifying that the installed protection measures provide the operationally required HEMP hardness for the completed system. If the prescribed testing results in any hardware damage or functional upsets, the operational authority for the system will make the determination whether the observed event is mission aborting.
MIL-STD-188-125-2 defines the design and testing criteria for specifically designated transportable ground-based systems in HEMP-hardened, critical, time-urgent C4I networks. Such systems include subscriber terminals and data processing centers, transmitting and receiving communications stations, and relay systems. The standard applies to both new systems and modifications of existing systems. Although only local portions of system interconnects are addressed, it is assumed that survivable long-haul communications paths, fiberoptic links, or other hardened interconnects between systems will be provided as required for mission accomplishment.
Survivable C4I capabilities are essential to a credible military deterrent. This standard supports nuclear survivability objectives by providing a standardized, low-risk protection approach for transportable ground-based systems in HEMP-hardened C4I networks. These uniform requirements ensure balanced HEMP hardening for all critical systems and facilities in the network.
