Gap Math
The runway is 20 months. The qualification timeline for small UAS LFP/NMC cells under MIL-PRF-32565 and equivalent Army DEVCOM test protocols runs 18 to 24 months from test package submission to qualification completion, based on historical program data from the past four qualification cycles. For 6T Li-ion, the timeline is longer — 24 to 30 months — because vehicle-level integration testing adds a phase that cell-level qualification does not require. A supplier submitting a 6T qualification package today, in May 2026, is targeting completion in late 2028 at the earliest. That is after the deadline.
Three domestic manufacturers are currently named or traceable in the qualified and in-qualification pipeline for small UAS LFP/NMC cells.
EaglePicher Technologies (Joplin, MO) holds existing MIL-SPEC qualification for select UAV cell formats and is expanding coverage to LFP chemistry under a SBIR Phase III contract awarded Q4 2025 — SAM.gov award N68335-26-C-0041, valued at $14.2 million. Phase III is production-intent; the distinction from Phase I and II matters here. At the disclosed facility expansion scale, editorial inference from contract value and floor-space filings puts credible annual output at 400,000 to 500,000 cells by the time the deadline applies.
Inventus Power (Woodridge, IL) submitted a qualification test package to Army DEVCOM in February 2026, per Inside Unmanned Systems reporting from March 2026. If the test cycle runs at the shorter end of the historical range — 18 months — qualification completes around August 2027, leaving roughly five months of production ramp before January 2028. Credible volume in that window: 150,000 to 200,000 cells annually, by editorial inference from disclosed facility capacity.
Paladin Energy Systems (Tucson, AZ) received a SBIR Phase II award in Q1 2026, valued at $3.1 million per SBIR.gov. Phase II is exploratory. No Phase III has been awarded. The earliest plausible qualification completion, assuming a Phase III award in late 2026 and an 18-month test cycle, is Q3 2027 — and that timeline assumes no test failures, no reformulation cycles, and a Phase III award that has not yet materialized. Paladin is in the pipeline. Volume by January 2028 is a separate question, and the answer is no.
Combined credible small UAS cell supply from EaglePicher and Inventus Power: 550,000 to 700,000 cells annually. DoD's projected annual demand for this category, as derived from the FY2026 Unmanned Systems Integrated Roadmap update reported by Breaking Defense in January 2026, is approximately 2.4 million units. Coverage: 23 to 29 percent.
For 6T Li-ion, the named pipeline is shorter. EaglePicher is pursuing LFP-chemistry 6T qualification, with estimated completion in Q2 2027 per company disclosure to Senate Armed Services Committee staff, as reported by Defense News in April 2026. Bren-Tronics (Commack, NY) is targeting a Q4 2026 qualification test package submission for 6T LFP, per a company press release from February 2026 — which, at the longer end of the 6T qualification timeline, puts completion in late 2028 or early 2029. Bren-Tronics is in active pursuit of a deadline that falls after January 2028.
Domestic supplier pipeline summary — as of May 2026:
| Supplier | Category | Qualification Status | Est. Completion | Credible Volume by Jan 2028 |
|---|---|---|---|---|
| EaglePicher Technologies | Small UAS LFP/NMC | Phase III awarded Q4 2025 | In progress | 400K–500K cells/yr |
| Inventus Power | Small UAS LFP/NMC | Test package submitted Feb 2026 | ~Aug 2027 | 150K–200K cells/yr |
| Paladin Energy Systems | Small UAS LFP/NMC | Phase II only (exploratory) | Q3 2027 at earliest | Not volume-credible |
| EaglePicher Technologies | 6T Li-ion | In qualification | ~Q2 2027 | 6K–9K units/yr |
| Bren-Tronics | 6T Li-ion | Targeting Q4 2026 submission | Late 2028–early 2029 | Not a Jan 2028 solution |
Combined credible 6T output from EaglePicher alone by the deadline: 6,000 to 9,000 units annually, against an editorially inferred DoD annual demand of approximately 38,000 units derived from Army vehicle fleet size and disclosed replacement cycle data. No direct public demand figure exists for this category; that inference should be weighted accordingly. Coverage: 16 to 24 percent.
What Moved — and What the Waiver Pattern Implies
Three program offices filed formal waiver requests with USD(A&S) for small UAS battery procurement scheduled to fall under the January 2028 new-contracts deadline, per SAM.gov pre-solicitation notices and congressional notification filings — this count is editorial inference from procurement pattern, not a directly sourced figure. That cluster of Q1 2026 filings, rather than any single contract award, is what makes this assessment timely.
Section 842 waiver authority rests with the relevant service secretary, who may certify on two grounds: domestic supply is unavailable in sufficient quantity or quality, or procurement at compliant prices would impose a cost premium exceeding 25 percent of the non-compliant alternative. Duration is up to two years, renewable once. Multi-year program waivers require congressional notification.
The timing of the Q1 2026 filings is the signal. A bridge waiver — filed when a qualified domestic supplier exists but hasn't yet reached volume — typically appears three to six months before a deadline. A waiver filed 20 months out, against a pipeline where the primary qualified supplier is still expanding chemistry coverage and the second-largest is mid-qualification, is not a bridge. It is a declaration that the mandate will not be met for that program on the current trajectory. Whether USD(A&S) treats these as temporary instruments or operational baseline will become visible in the renewal pattern starting in 2027. The first renewals will answer the question the first invocations only raise.
BlueUAS platform certification is a platform-level designation. A platform on the BlueUAS approved list may still require a battery-level waiver if its cells are sourced from FEOC-linked suppliers — platform certification and battery FEOC compliance are separate determinations, and conflating them produces incorrect assumptions about which contracts are covered by the January 2028 deadline.
Other Deadlines — Status Lines
January 2029 — standard batteries (non-UAS, non-6T). The FY2026 NDAA conference report, enacted December 2025, directed DoD to submit a qualified domestic supplier assessment for this category by March 2027. That assessment has not yet been filed. No new qualification completions or production-intent contract awards in this category have been recorded since December 2025. Gap assessment: static.
January 2031 — existing programs. Army Program Executive Office Ground Combat Systems confirmed in March 2026 that legacy program battery contracts will be reviewed for FEOC compliance ahead of the 2031 deadline, per National Defense Magazine reporting from that month. The 2031 runway is, in principle, sufficient for qualification cycles to complete if procurement decisions are made by 2028. No significant signal has moved this assessment since March 2026. Gap assessment: too early to characterize meaningfully, contingent on decisions that have not yet been made.
