MIL-HDBK-423, HIGH-ALTITUDE ELECTROMAGNETIC PULSE (HEMP) PROTECTION FOR FIXED AND TRANSPORTABLE GROUND - BASED C4I FACILITIES - VOLUME 1 - FIXED FACILITIES (15 MAY 1993)., The two-volume MIL-HDBK-423 handbook set provides information to managers and engineers responsible for the design, construction, testing, and hardness maintenance/hardness surveillance of fixed and transportable ground-based facilities that must be hardened against the high altitude electromagnetic pulse (HEMP). The primary purpose of this Volume I is to provide detailed guidance to implement HEMP protection of fixed facilities in accordance with requirements of MIL-STD-188-125, "High Altitude Electromagnetic Pulse (HEMP) Protection for Ground-Based C4I Facilities Performing Critical, Time Urgent Missions." Volume II provides similar guidance for ground-mobile and transportable facilities. - THIS IS A CONTROLLED DISTRIBUTION DOCUMENT AND NOT IN THE PUBLIC DOMAIN -
