China has long known about nuclear high-altitude electromagnetic pulse (HEMP) and invested in protecting military forces and critical infrastructures from HEMP and other nuclear weapon effects during the Cold War, and continuing today. China has HEMP simulators and defensive and offensive programs that are almost certainly more robust than any in the United States. China’s military doctrine regards nuclear HEMP attack as an extension of information or cyber warfare, and deserving highest priority as the most likely kind of future warfare.

DHS Electromagnetic Pulse (EMP) Protection and Restoration Guidelines for Equipment and Facilities
The EMP protection guidelines presented in this report were initially developed by Dr. George H. Baker, based on his previous work where he led the Department of Defense program to develop EMP protection standards while at the Defense Nuclear Agency (DNA) and the Defense Threat Reduction Agency (DTRA). He is currently serving as a consultant to the Department of Homeland Security (DHS) and is emeritus professor of applied science at James Madison University (JMU). He presently serves on the Board of Directors of the Foundation for Resilient Societies, the Board of Advisors for the Congressional Task Force on National and Homeland Security, the JMU Research and Public Service Advisory Board, the North American Electric Reliability Corporation GMD Task Force, the EMP Coalition, and as a Senior Scientist for the Congressional EMP Commission.

High Altitude Electromagnetic Pulse (HEMP) and High Power Microwave (HPM) Devices: Threat Assessments
Electromagnetic Pulse (EMP) is an instantaneous, intense energy field that can overload or disrupt at a distance numerous electrical systems and high technology microcircuits, which are especially sensitive to power surges. A large scale EMP effect can be produced by a single nuclear explosion detonated high in the atmosphere. This method is referred to as High-Altitude EMP (HEMP). A similar, smaller-scale EMP effect can be created using non-nuclear devices with powerful batteries or reactive chemicals. This method is called High Power Microwave (HPM). Several nations, including reported sponsors of terrorism, may currently have a capability to use EMP as a weapon for cyber warfare or cyber terrorism to disrupt communications and other parts of the U.S. critical infrastructure. Also, some equipment and weapons used by the U.S. military may be vulnerable to the effects of EMP.
