The test procedures of MIL-STD-188-125, which are used todemonstrate HEMP (high-altitude electromagnetic pulse) hardness of fixedground-based communications sites, are considered. Currently existing asa draft, the standard establishes a minimum specification for thedesign, engineering, fabrication, installation, and testing ofground-based facilities which perform critical, time-urgent command,control, communications, computer, and intelligence (C4I)missions. Three categories of testing, shielding effectiveness, pulsedcurrent injection, and low-level continuous wave (CW) immersion, areintegrated in the standard's HEMP hardness evaluation process. Prototypetest equipment, used to perform current injection and CW immersionprocedures, was deployed in Europe to support a NATO test program whichestablished hardness maintenance baselines for ground basedC3I facilities. The details of these tests and performancedata for the mobile, integrated test equipment are presented
