From the Document: "Many defense analysts consider electronic warfare [hyperlink] (EW), which disrupts an adversary's command and control networks, a critical 21st -century combat capability. During a March 19, 2021, House Armed Services Subcommittee on Cyber, Innovative Technologies and Information Systems hearing [hyperlink], several EW experts noted that China and Russia have developed sophisticated EW expertise. Such expertise raises potential concerns that either country may challenge the U.S. military's ability to access the electromagnetic spectrum. At the hearing, Representative Langevin remarked, 'Future combat will be less about the capability of individual weapon systems and more about how a network of systems communicate and work together through the use of the electromagnetic spectrum.' EW has become a priority issue for both the executive branch and Congress. To facilitate congressional oversight, this Insight analyzes changes in FY2019-FY2022 Research, Development, Test, and Evaluation (RDT&E) and procurement funding requests, tracks the proportions of RDT&E investments by budget activity, and examines funding trends within military departments."
