Title

DoD IT modernization, zero trust, spectrum, and AI adoption posture

Purpose

The House Armed Services Subcommittee on Cyber, Information Technologies, and Innovation held this hearing on May 8, 2025, to receive testimony from the Department of Defense's acting Chief Information Officer and its Chief Digital and Artificial Intelligence Officer on IT infrastructure, zero trust implementation, spectrum policy, and the department's strategy for adopting data and artificial intelligence. Members questioned the witnesses on spectrum protection for Golden Dome, DoD-VA data interoperability, the Signal/TeleMessage hacking controversy, and AI's energy and chip-supply requirements. Begins at0:22:07

Who spoke

Chairman Don Bacon (R-NE)0:22:07: Opened by stressing that the U.S. cannot fall behind on AI and quantum computing given the risks to communications security0:22:27; later questioned Katie Arrington on why the lower 3 GHz spectrum band matters0:35:21 and Dr. Maddie on the placement of the CJADC2 (JADC2) portfolio0:36:46.

Ranking Member Khanna0:23:24: Said the subcommittee looks forward to hearing about the zero trust ecosystem, cloud computing, and CDAO's efforts to responsibly integrate AI0:23:51; later asked Dr. Maddie about the value of research universities like MIT and pressed him on NSF funding cuts to MIT0:38:310:40:16.

Katie Arrington, Acting DoD Chief Information Officer0:24:21: Outlined efforts on zero trust (target by FY27), CMMC, ICAM federation, and streamlining software procurement through a digital catalog0:25:320:26:46; said the lower 3.1–3.45 GHz spectrum band carries roughly 7,000 platforms and weapon systems and is essential to Golden Dome0:35:21; confirmed TeleMessage/SMARSH is not currently used for DoD communications and no CUI is sent via Signal on government devices0:49:440:50:41; described new data-labeling and ICAM standards meant to fix broken DoD-to-VA records transfer0:53:17.

Dr. Maddie, Chief Digital and Artificial Intelligence Officer0:29:57: Described CDAO's "enable, speed, scale" approach to AI adoption, VAULTIS data principles, and the GIDE experimentation series0:32:400:33:31; outlined four facets of responsible AI — technical, ethical, legal, and policy — and a 16-nation AI partners council0:58:24.

Rep. McCormack0:41:42: Asked how the Defense Innovation Unit and CDAO keep pace with faster CCP decision-making on tech contracts0:42:08; asked Arrington how she coordinates more than 30 DoD component CIOs0:44:00.

Rep. Whitesides0:46:31: Asked Maddie how DoD develops a roadmap for AI's offensive and defensive applications0:46:59; questioned Arrington on TeleMessage, the Signal hack, and whether the national security adviser's use fell under different rules0:49:160:50:41; in a follow-up round asked how DoD legally archives Signal messages absent SMARSH, prompting Arrington to offer a classified answer1:08:56.

Rep. Luttrell (referred to as "Latrell"/"Lrol")0:51:39: Raised the failure of DoD medical records to transfer seamlessly to the VA and pressed for confirmation that DoD and VA leadership are actively addressing it0:52:220:54:38.

Rep. Vindman (referred to as "Vinman")0:56:42: Asked how AI targeting decisions are balanced against law-of-war obligations, citing his own military and JAG background0:57:12; raised Ukraine's digital-transformation app as a model for streamlined, secure government records0:59:41.

Rep. Crank1:02:05: Asked Dr. Maddie how DoD ensures AI/ML systems operate at "speed of mission" in contested, denied environments1:02:59 and how AI/ML supports real-time cyber threat detection, prompting Arrington to describe continuous red-teaming under zero trust1:05:001:05:53; in a later round, got confirmation that roughly 425 MHz of spectrum could be shared or sold in reconciliation talks but that the lower 3 GHz band is excluded1:17:10.

Rep. McGuire1:23:32: Asked how DoD will secure enough energy to scale AI given ChatGPT-scale power demands1:23:32; noted 99% of advanced chips are made in Taiwan and asked about U.S. chip manufacturing strategy1:26:31.

Key moments

Arrington said the lower 3.1–3.45 GHz spectrum band carries roughly 7,000 DoD platforms and weapon systems and called it "golden" and essential to achieving Golden Dome0:35:210:35:50.

Arrington confirmed the TeleMessage archiving product used by senior officials, including the former national security adviser, was hacked, but said DoD does not currently use the "SMARSH" capability and prohibits sending CUI via Signal on government devices0:49:440:50:41.

Whitesides pressed on the seam between DoD and NSC communications policy; Arrington said DoD only has authority over its own device policies and referred questions about the national security adviser's practices to the NSC and Secretary of Defense's office1:10:371:11:12.

Whitesides asked how DoD legally captures Signal messages absent SMARSH; Arrington said she could only answer that at a classified level1:08:56.

Luttrell said DoD-to-VA medical record transfer "absolutely does not work," and Arrington said her office is building new data-labeling, tagging, and ICAM standards to fix it, confirming active coordination with new VA leadership0:53:170:54:38.

Crank confirmed with Arrington that about 425 MHz of spectrum has been identified as shareable/sellable through the FCC as part of reconciliation discussions, but that the lower 3 GHz band remains off the table1:17:101:17:30.

Maddie described CDAO's "responsible AI" framework as spanning four facets — technical, ethical, legal, and policy — coordinated through a 16-nation AI partners council meeting roughly every six months0:58:240:58:41.

McGuire cited an estimate that ChatGPT consumes enough energy annually to power over 20,000 homes; Arrington pointed to micro nuclear reactors, including a roughly 50-megawatt unit being developed by BWXT in McGuire's district, as a path to power AI compute securely1:23:321:25:42.

McGuire noted 99% of top-tier chips are manufactured in Taiwan; Arrington said she recently met with Nvidia's CEO and the deputy secretary about new U.S. chip manufacturing investment, alongside Texas Instruments1:26:551:27:25.

Arrington said any DoD component CIO who believes their systems are uniquely different must justify that to her office, as part of an effort to end "disparate information stovepipes" across more than 30 component CIOs0:45:070:45:35.
