Lead deadline: January 1, 2028 — new acquisition programs Battery category: Rechargeable lithium-ion cells for Group 2-3 UAS Trigger: P550 Long Range Reconnaissance production contract, 82 systems
AeroVironment's P550 production contract, awarded March 2026 for 82 all-battery-endurance reconnaissance systems, is the first major drone procurement that will run directly into Section 842's new-contract deadline. No domestic rechargeable cell producer is publicly confirmed as qualified for a named drone-program contract at production volume. Nineteen months remain. Typical defense battery qualification runs 18 to 36 months.
The contract value appears as $132 million in AeroVironment's own investor disclosure (December 2025 announcement) and as $117.3 million in subsequent defense trade press reporting of the March 2026 production award. The delta likely reflects base firm-fixed-price versus total ceiling including options, but the discrepancy is unresolved in public sources.
The gap has three layers, and they compound.
Layer 1 — Mandate vs. supply
The P550 delivers five hours of battery-powered VTOL flight. That endurance figure implies high-energy-density NMC or silicon-anode cells at a power-to-weight ratio eliminating most commercial formats. The cell supplier is not identified in the award documentation.
The publicly known supplier relationship is AeroVironment-to-Amprius, whose silicon-anode cells are manufactured in China for non-NDAA applications. Amprius's NDAA-compliant pathway, announced February 2026, routes final assembly through Nanotech Energy in Chico, California. Final assembly location satisfies one condition under Section 842. The statute separately requires 95% of functional component costs from non-FEOC sources and prohibits batteries produced using technology licensed from a FEOC entity. Amprius has not publicly disclosed cathode, anode precursor, separator, or electrolyte sourcing for its U.S.-assembled line. The technology-license prohibition operates upstream of component sourcing entirely. For a silicon-anode company whose core cell architecture was developed with deep roots in the Chinese battery R&D ecosystem, the fundamental cell design must independently clear the technology-license bar, regardless of assembly location or materials sourcing. Amprius itself acknowledges that compliance "requires vetting not just final packaging, but also the origin of all raw materials, anode and cathode components, and even battery management system firmware." IP provenance is harder to trace than materials origin, and no audit methodology exists to verify it. No DoD production contract has been named.
The only domestic cell manufacturer with a live DoD contract for UAS batteries is Packet Digital's Badland Batteries subsidiary. In May 2026, Packet Digital received $9.8 million for Phase 3 of a Navy SBIR, following a $27 million NAWCAD Phase III award in April. The North Dakota factory is commissioning equipment and validating supply chains. It is not in volume production. Phase 3's stated objective is scaling throughput and qualifying production equipment. The company describes its cells as "NDAA-compliant" in press materials. That self-description has not been independently verified against the 95% functional-component-cost test. Cathode, anode, and electrolyte suppliers are not publicly named.
That is the domestic supply picture for drone/UAS cells as of June 9, 2026: one company commissioning a factory under a Navy SBIR, another assembling a partner's cells with undisclosed upstream sourcing and unresolved technology-license exposure. Zero production-qualified cells confirmed against any Army drone platform specification.
Layer 2 — Mandate vs. enforcement mechanism
Section 842 is law. No DFARS proposed rule translating it into contract clause language has been published. The open DFARS cases list as of May 15 does not include a battery-specific rulemaking. Without a DFARS implementing clause, contracting officers have no standard mechanism to require Section 842 compliance attestation in solicitations or award documents. The P550 and VAPOR CLE award announcements contain no publicly visible battery-sourcing or FEOC compliance language. Consistent with the absence of a clause requiring it.
The adjacent FOCI proposed rule (DFARS Case 2021-D011, published May 7, comments due July 6) creates ownership-disclosure infrastructure that could eventually support battery supply chain auditing. It covers ownership disclosure, not battery sourcing.
Layer 3 — Mandate vs. audit infrastructure
Three statutory provisions were supposed to build the compliance infrastructure ahead of the January 2028 deadline. None shows visible progress.
| Provision | Requirement | Deadline | Status (June 9) |
|---|---|---|---|
| Section 837 | Working group on qualification bottlenecks | ~June 16, 2026 | No public output, meeting notice, or industry engagement |
| Section 836 | Voluntary compliance repository | January 1, 2027 | No beta launch, stakeholder notice, or Federal Register entry |
| DFARS rule | Enforceable contract clause language | No timeline established | No proposed rule published |
The Section 836 repository deadline also marks the expiration of the FCC's BlueUAS exemption, meaning two distinct infrastructure deadlines converge on January 1, 2027 with neither showing visible progress.
Section 833's national security waiver authority allows interim relief when contractors discover noncompliant sources. No waiver invocation has become publicly visible through the required 5-day congressional notification. The waiver authority expires January 1, 2028, the same date as the deadline it is meant to bridge.
What moved
P550. New acquisition through the UAS Marketplace BOA. Any follow-on orders or modifications after January 1, 2028 trigger the new-contract deadline regardless of the original award date. AeroVironment's SEC filings have not been confirmed to disclose Section 842 compliance plans for this platform (a research gap requiring direct EDGAR review of the most recent 10-Q). Supply analysis above.
VAPOR CLE. AeroVironment received $14.6 million for its all-electric VTOL under the Company-Level Directed Requirement SUAS, Tranche 2, awarded April 20. Different contracting vehicle from the P550's BOA. No publicly available guidance distinguishes CoLvl DR from BOA for Section 842 purposes; absent such distinction, the compliance exposure is identical. Cell supplier undisclosed.
FMS IDIQ. The $874.26 million FMS IDIQ was awarded December 8, 2025, ten days before Section 842's enactment. It covers Groups 1-3 UAS including P550 for allied nations. FMS procurement operates through DoD's acquisition system under the same standards as domestic purchases. No FMS-specific exemption from Section 842 has been identified in the statute or conference report. Individual task orders placed after January 2028 would arguably constitute new acquisitions. This is editorial inference from statutory text and FMS operational structure; no contracting officer guidance specific to this intersection has been published. If FMS task orders trigger the deadline, the compliance question scales well beyond 82 systems.
Other deadlines
January 1, 2029 — standard batteries. Covers standard-form-factor procurement (6T, BB-2590). Last significant signal: Epsilor's MIL-PRF-32565C Type 2 certification campaign (Israeli manufacture, upstream cell sourcing undisclosed). No new signal since Q1 2026. Gap assessment: static.
January 30, 2031 — existing acquisition programs. No significant change since enactment. The mechanism for formally identifying which programs qualify as "existing" has not been established in the absence of a DFARS rule. Gap assessment: static.
Sequencing
The three implementation prerequisites, in order: the Section 837 working group identifies qualification bottlenecks (deadline next week, no output visible), the Section 836 repository provides an attestation mechanism (deadline January 2027, no launch visible), and a DFARS rule gives contracting officers enforceable clause language (no timeline visible). Behind all three, factories are commissioning, partnerships have been announced, and production contracts remain absent.
Nineteen months is enough time to qualify a cell if the cell exists, the test methodology exists, and the contract language exists. As of today, the rate of closure on all three is indistinguishable from zero.
If the implementation gap persists, Section 833's national security waiver becomes the de facto compliance pathway for every drone contract crossing the January 2028 line. The waiver authority expires on the same date.
- DFARS FOCI comment deadline: The May 7 proposed rule on foreign ownership disclosure obligations affecting an estimated 40,000 defense contractors closes for public comment on July 6, and the resulting disclosure infrastructure will shape how battery supply chain audits eventually work.
- Badland Batteries supply chain: Packet Digital's Phase 3 objective is explicitly to validate large-scale material supply chains for its North Dakota cell plant, and whether cathode and anode suppliers are named publicly will determine if the "NDAA-compliant" claim can bear weight.
- FCC BlueUAS exemption expiry: The January 1, 2027 expiration of the FCC carve-out for Blue UAS Cleared List platforms from the Covered List creates a communications-authorization gap that hits before Section 842 does, and no extension has been announced.
- AeroVironment fiscal year filing: AeroVironment's FY2026 10-K (fiscal year ending April 30, 2026) should be filed by late June and may contain the first public disclosure of the company's Section 842 compliance posture for P550 and VAPOR CLE battery sourcing.
