From the Highlights: "The spectrum is essential for facilitating control in operational environments and affects operations in the air, land, sea, space, and cyberspace domains. Spectrum use is pervasive across warfighting domains and thus maintaining or achieving spectrum superiority against an adversary is critical to battlefield success. This statement summarizes: (1) the importance of the spectrum; (2) challenges to DOD's superiority in the spectrum; and (3) the extent to which DOD has implemented spectrum-related strategies and is positioned to achieve future goals. This statement is based on GAO's [Government Accountability Office] December 2020 report (GAO-21-64 [hyperlink]) and updates conducted in March 2021. For the report, GAO analyzed 43 studies identified through a literature review, reviewed DOD documentation, and interviewed DOD officials and subject matter experts. For the updates, GAO reviewed materials that DOD provided in March 2021."
