scope:

This Standard establishes design margin, performance metrics, and test protocols for high-altitude electromagnetic pulse (HEMP) protection of military aircraft with nuclear EMP survivability at three hardness levels: level I, level II and level III. This Standard may also be used for aircraft that support multiple missions. Subsystems of the aircraft required to fully comply with the provisions of the Standard will be designated as Mission-Critical Subsystems (MCS) having an HEMP survivability requirement. This approach also allows for consideration of platforms not yet addressed in this Standard, such as UAVs.
