The HASC approved its FY27 NDAA after working through ~900 amendments. Three stand out for defense allocators: covered AI exclusions, commercial data procurement, and mature-node chip supply.
The House Armed Services Committee approved its version of the FY2027 National Defense Authorization Acton June 4, voting 44 to 12 after working through roughly 900 amendments over about 14 hours.
Committee passage is adirectional signal, not enacted law, and an authorization is not anappropriation. With that caveat, here are three adopted amendments worthtracking through the congressional process.
An amendment introduced by Rep. Don Bacon (R-NE) puts a hard clock on the Department’s exclusion of certain AI vendors. It amends Section 1532 of the fiscal 2026 NDAA to require the Secretary of Defense, within 30 days of the fiscal 2027 bill’s enactment, to issue Department-wide guidance both to identify “covered artificial intelligence companies” and to establish processes to exclude and remove AI developed by those companies from Department systems and devices. A companion change converts a conditional prohibition in the underlying statute into a fixed 90-day clock once its triggering condition is met. The defining criteria for a “covered” company sit in the fiscal 2026 statute that this amendment accelerates, not in the amendment itself.
Why it matters. This is the AI analog to the Section 889 covered-entity exclusion regime that previously targeted specific telecom and software vendors. It creates a compliance gate and, conversely, a competitive moat for vendors that can certify they are clean of designated (almost certainly adversary-linked) AI. The 30-day deadline signals the committee wants designations to move quickly. The open questions for diligence are which companies get designated and whether “developed by ”reaches models with adversary-origin training lineage or open-weights derivatives.
Three adopted amendments push the Department toward buying commercial data rather than building and owning it:
Rep. Jeff Crank (R-CO) directs a briefing on folding commercially sourced data into the Space Force’s HighAccuracy Catalogue for space-domain awareness.
Rep. George Whitesides (D-CA) directs the Space Force’s commercial space office to procure commercial space-based data and end products to support wildfire-countering efforts.
Rep. John McGuire (R-VA) directs a briefing on commercial weather and environmental data acquisition across the Department, including unmet data requirements, acquisition timelines, and government data-ownership challenges.
Why it matters. The pull is consistently toward data as a service across space-domain awareness, Earth observation, and weather. The recurring friction, government data ownership versus licensing, is the contract-terms battleground for commercial data vendors. It determines whether these become durable recurring-revenue relationships or one-time buys.
Directive report language introduced by Rep. Mark Messmer (R-IN) presses the Pentagon on a growing mismatch in its chip supply. Federal semiconductor investment has flowed mostly to next-generation, leading-edge production, while mature-node (trailing-edge)chips, the components that actually populate fielded weapon systems, have drawn far less attention on the assured-access side. The committee notes the Department is already stockpiling mature-node parts, expanding trusted-foundry partnerships, and developing alternatives through reverse-engineering, but argues that sustaining readiness amid shrinking mature-node availability will require long-term policy and funding commitments. It directs the Assistant Secretary of Defense for Industrial Base Policy to brief the committee by April1, 2027, on efforts to address that risk, with specific interest in the chips used in anti-drone, anti-armor, anti-missile, and anti-mortar munitions.
Why it matters. The chip market is pouring capital into the newest, most advanced semiconductors, which are the ones that run AI. Weapon systems are built around older, simpler chips designed decades ago and expected to stay in the field for 20-plus years. As commercial fabs chase cutting-edge production, fewer of them still make those older parts, so supply is shrinking exactly where defense demand is locked in. The opportunity sits with companies that still manufacture mature-node chips, with trusted foundries cleared to serve defense, and with firms that keep discontinued parts available or reverse-engineer them. The committee’s specific call-out of munitions (anti-drone, anti-armor, anti-missile, anti-mortar) shows where the shortage bites hardest. The caveat is that this is a briefing requirement by April 2027, not a funding line, so it points to where committee attention and future dollars are heading rather than where they are today.
The measure now moves toward the House floor before the July recess, while the Senate Armed Services Committee marks up its own version next week.
