Automotive Ground Vehicles’ Resilience to HEMP Attack: An Emergency Management Mitigation Plan

Abstract

United States exposure to attack from a nuclear weapon of mass destruction (WMD) optimized to generate a high-altitude electromagnetic pulse (HEMP) is a concern in national security forums. Such an attack could lead to widespread damage to the electrical components of many critical infrastructures. The purpose of this study was to develop a framework to better understand the hazard risks from a HEMP attack on non-military (non-MIL), “electronics-heavy” automotive ground vehicles that could inform an effective emergency management response and recovery plan. A hybrid emergency management and engineering hazards risk analysis utilizing a Failure Modes and Effects Analysis (FMEA) format helped visualize the critical vehicle electronics subsystems and components, and their respective potential failure modes. A design of experiments test plan was developed to quantify the risks, and to develop a pathway to validate cost-effective mitigation countermeasures based on present-day best practices for HEMP hardening. The proposed emergency management plan emphasized strategic implementation of HEMP mitigation countermeasures to support continuity in emergency services and delivery of community lifelines to the public. The results of this study will serve as a foundation for future HEMP projects with automotive ground vehicles that will support the FEMA National Preparedness Goal, Presidential Executive Order 13865, and the recent FY2020 National Defense Authorization Act (NDAA) legislation. The methodologies can also apply to other critical infrastructure segments.
