HASC FY27 NDAA: Autonomous Weapons Guardrails Hit Defence AI Stack

LONDON, Wednesday, June 10, 2026 — The House Armed Services Committee advanced H.R. 8800, the Fiscal Year 2027 National Defense Authorization Act, in a 44-12 vote following a June 4 markup, with new language shaping how the Pentagon can buy and field autonomous weapons and frontier AI. Ranking Member Adam Smith confirmed committee passage of the bill after the markup. The vote landed five days after Britain's Ministry of Defence published its intent to directly award an AI military decision-support contract called Project STRONG. It also followed a May 1 Pentagon deal with eight tech firms — and the conspicuous omission of Anthropic. The defence AI stack is being rewritten in real time.

Key Takeaways

• HASC advanced FY27 NDAA provisions combining emerging military tech support, acquisition reform and oversight, with new autonomous-weapons language attached.
• UK MoD published a transparency notice indicating a planned direct award of just under £227,000 (before VAT) to London-registered Defence Holdings PLC for Project STRONG, a three-month AI decision-support prototype, subject to standard procurement approvals.
• The Pentagon's May 1 classified-network deal covers SpaceX, OpenAI, Google, Microsoft, Nvidia, AWS, Oracle and Reflection — Anthropic is excluded.
• Anduril's 10-year Army enterprise contract worth up to $20 billion consolidates more than 120 prior procurement actions.
• Anduril told Fortune its 2026 revenue projection is $4.3 billion, up from $2.2 billion in 2025, according to Fortune (May 2026).

Context & Analysis

The defence AI market has spent six months consolidating around a small group of platform vendors. In March, the U.S. Army signed a 10-year deal with Anduril worth up to $20 billion, structured as a five-year base with a five-year option covering hardware, software, infrastructure and services. That followed a 10-year, up-to-$10 billion Army enterprise agreement with Palantir last year that consolidated roughly 75 software and data contracts.

Then came the rupture. On February 24, Defense Secretary Pete Hegseth gave Anthropic CEO Dario Amodei a deadline of 5:01 p.m. Friday February 27 to allow unrestricted use of Claude; on February 27 President Trump directed federal agencies to cease using Anthropic products and Hegseth designated the firm a supply chain risk. A federal judge in California's Northern District granted a preliminary injunction on March 26 blocking enforcement, finding the government's actions likely violated the law.

Competitive Landscape

The June 4 NDAA markup hardened a procurement framework that already favours integrated platforms over point tools. The committee directed attention toward layered defences including kinetic interceptors, directed-energy weapons, electronic warfare and autonomous counter-drone platforms, echoing lessons from Ukraine and the Middle East. That language maps cleanly onto Anduril's Lattice stack and Palantir's data backbone.

Frontier model vendors are now stratified by contractual posture. The DoD's May 1 classified-network agreement covers SpaceX, OpenAI, Google, Microsoft, Nvidia, AWS, Oracle and Reflection — but not Anthropic, which the administration blacklisted over safety carve-outs. OpenAI's published agreement keeps a multi-layered safety approach with cloud deployment, cleared OpenAI personnel in the loop and contractual protections. Anthropic's $200 million CDAO prototype OTA, awarded in July 2025, has been described by some analysts as 'functionally dead' following the supply-chain-risk dispute, though the company's preliminary injunction win on March 26 blocks enforcement of the broader ban.

Britain's move is small in dollars but heavy in signal. The contract goes to Defence Holdings PLC, a London-registered SME, for just under £227,000 before VAT, covering three months from mid-June. It is awarded directly under Schedule 5 of the Procurement Act 2023 and the defence and security regime, using a provision covering prototypes. Project STRONG fuses intelligence into a single analytical platform, generates courses of action, and supports rapid human-controlled deployment of authorised effects across cyber, information and supply-chain domains.

What It Means

For Enterprise Buyers

Procurement officers should expect the platform model to spread. Anduril's contract copies and extends Palantir's playbook by wrapping hardware and services around the software, doubles the ceiling and ties the whole thing to a live mission of countering drones — a pattern of VC-backed platforms winning prime-like enterprise deals. Buyers locked into bespoke integrators face migration pressure. The classified-network bake-off effectively settles the foundation-model question for sensitive workloads, with eight cleared vendors now on the menu.

For Investors

The valuation logic is shifting from manufacturing to software. Anduril announced a $5 billion Series H in May 2026 at a $61 billion valuation, led by Thrive Capital and Andreessen Horowitz, according to the company. PitchBook's Ali Javaheri noted the government increasingly sees Anduril's stack as repeatable and scalable rather than bespoke R&D. Javaheri also said autonomy, counter-UAS and software-defined C2 are moving from experimental budgets into more durable procurement pathways, according to PitchBook commentary. The NDAA guardrails do not slow this — they entrench the incumbents who already have safety stacks documented.

Forward Outlook

Next milestones are concrete. Project STRONG's earliest signing date is June 15. The Pentagon's Low-Cost Containerized Munitions assessment phase begins purchasing test missiles from Anduril, CoAspire, Leidos and Zone 5 in June 2026. June 2026 also brings DFARS revisions including a "loser pays" rule on GAO bid protests and a comprehensive DoW review of commercial product procurements. Space Force intends to award an initial RG-XX task order under the $1.8 billion Andromeda program with the goal of satellites in orbit by 2030. Senate NDAA markup follows.
