Why it Matters

The White House's proposal to cut Pentagon research and development spending by roughly one-third, a reduction of approximately $4.5 billion, sets the stakes for the Senate Armed Services Committee's Subcommittee on Emerging Threats and Capabilities. It convenes Tuesday May 19 to examine science and technology priorities tied to the fiscal year 2027 defense authorization.

The Pentagon is simultaneously pursuing a budget increase in autonomous warfare spending that's 243 times larger than the same period last year, while also restructuring the very boards it relies on for science and innovation advice, and signing AI deals with commercial tech giants for classified military work. Congress is being asked to bless a Pentagon defense budget that cuts R&D while pouring resources into a narrow set of emerging technologies.

A Budget That Cuts Basic Research While Betting on Autonomy

According to reporting by Defense One, Pentagon R&D spending would drop by about one-third under the White House's proposal, with the industry's willingness to self-fund research cited as a potential cushion. The overall Research, Development, Test and Evaluation account is reported to sit at just under $220 billion, while the procurement account is just under $260 billion, according to Pentagon officials cited by the law firm Greenberg Traurig.

At the same time, the Association of Public and Land-grant Universities submitted a formal fiscal year 2027 appropriations request for $23.089 billion in Department of Defense Science and Technology funding across basic and applied research categories, up from $21.782 billion enacted in fiscal year 2026. The gap between what research institutions are requesting and what the administration proposed to cut is precisely the kind of question the subcommittee will want to probe.

Set against those cuts, the Pentagon's proposed autonomous warfare budget represents a 24,300 percent year-over-year increase, according to Technocracy News & Trends. The subcommittee will need to examine whether that move would come at an acceptable cost to the broader science and technology defense priorities that underpin long-term military competitiveness.

AI Deals and the Anthropic Dispute

In early May, the Pentagon announced agreements with eight AI companies, including SpaceX, Google, OpenAI, Microsoft, and Amazon, to integrate artificial intelligence into classified military networks. That deals land squarely within the subcommittee's jurisdiction over emerging threats and capabilities, raising immediate questions about oversight, safeguards, and how commercial partnerships interact with the Pentagon's own internal research priorities, particularly given the proposed cuts to basic science funding.

The announcement followed a publicized dispute with AI company Anthropic, which refused to allow its products to be used for autonomous weapons or domestic surveillance of Americans, according to reporting by The Guardian. The Washington Post reported that the round of deals "follows a bitter fight between officials and AI lab Anthropic over surveillance and autonomous weapons." The disagreement exposed the legal and ethical fault lines in the Pentagon's drive to commercialize its AI capabilities. Senators on both sides of the aisle are likely to question what guardrails exist as these partnerships expand.

Drone Swarms and the Future Years Defense Program

Defense One reported in May that the Pentagon is actively seeking smarter, self-organizing drone systems to allow a small number of human operators to direct far larger numbers of autonomous robots on the battlefield. The development is central to the future years defense program review the subcommittee is tasked with examining, as autonomous systems are increasingly positioned as a cornerstone of the Pentagon's long-range force planning.

The congressional hearing on defense science and technology priorities will need to address how these investments are sequenced against the broader R&D cuts. If the administration is reducing the foundational research that produces next-generation capabilities while simultaneously accelerating procurement of current autonomous systems, the subcommittee will want to understand the long-term risk this creates for American technological advantages.

A Reorganized Science Advisory Structure Amid Cuts to University Research

Earlier this year, the Trump administration merged the Defense Science Board (DSB) and the Defense Innovation Board (DIB) into a new combined science-and-innovation board. The structural change arrived simultaneously with reductions to basic research funding at U.S. universities. As Defense One reported in February, "the DSB-DIB merger comes as the Trump administration reduces funding for basic sciences," citing provisions in the fiscal year 2026 National Defense Authorization Act that cut support for basic research at U.S. institutions.

For the subcommittee examining the fiscal year 2027 defense authorization, this reorganization raises structural questions. They will need to consider whether consolidating advisory bodies, while cutting the research base that those bodies are meant to guide, represents a coherent science and technology strategy or an institutional mismatch that will surface in future capability gaps.

The Hearing

The Subcommittee on Emerging Threats and Capabilities, chaired by Sen. Joni Ernst (R-IA) with Sen. Elissa Slotkin (D-MI) as ranking member, convenes Tuesday, May 19 at 222 Russell Senate Office Building. The full Armed Services Committee membership participating includes Sens. Tom Cotton, Roger Wicker, Mark Kelly, Kirsten Gillibrand, Gary Peters, Tim Kaine, Jack Reed, Ted Budd, Mike Rounds, Kevin Cramer, Tim Sheehy, Jeanne Shaheen, Jacky Rosen, Eric Schmitt, and Ashley Moody.
