Based on budget documents of the US Department of Defense as well as the country’s Navy, Air Force, and Space Force for FY2021, this study identifies 12 issues related to scientific research activities on the Nuclear Electromagnetic Pulse (NEMP), and details their main contents and concerns through statistical comparisons. The results showed that these issues fell in the category of “research, development, test, and evaluation”, and involved six of the eight sub-categories of the scientific research budget on national defense for a total of 528 million US dollars. In general, the research on NEMP in FY2021 can be divided into three main categories: NEMP hardening and protection for missile defense and nuclear weapons; high altitude electromagnetic pulse survivability test and evaluation of weapons and systems; and radiation, nuclear threat detection, and material development. Research by the US on the NEMP has four characteristics: investment on the NEMP closely follows the latest strategic objectives and requirements of the US military; traditional NEMP research projects continue to compensate for the lack of ability; the research budget for the NEMP has been adjusted over time according to the phase of weapons development; the research budget for NEMP is small, but the area is important.
