Even random attacks using NNEMP weapons against less than 100 EHV transformer control substations located in all three U.S. grid systems—Eastern, Western, and Texas—would probably suffice to inflict a protracted nationwide blackout.
Dozens of nations reportedly have NNEMP weapons or are developing them. Some of these are Russia, China, North Korea, Iran, Pakistan, India, Israel, Germany, the United Kingdom, France, Australia, and Switzerland.
Non-Nuclear EMP weapons, as a cutting-edge military technology, are being developed largely clandestinely, with relatively little detailed open source reporting on specific national programs, let alone on what terrorists may be doing.
Relatively small numbers of NNEMP cruise missiles or drones—perhaps only one capable of protracted flight—could inflict a long nationwide blackout.
20 NNEMP trucks could damage 580 EHV transformer substations in 24 hours, 430 substations in the East, 120 substations in the West, 30 substations in Texas—29% of all substations nationwide. The “army” manning 20 NNEMP trucks would number just 40 men.
U.S. military power projection capabilities would be severely crippled or altogether paralyzed by a protracted nationwide blackout. CONUS military bases depend upon the civilian electric grid for 99% of their electric power.
