Research publicly disclosed Pentagon and Defense Logistics Agency…

The National Defense Stockpile (NDS), managed by the Defense Logistics Agency (DLA) Strategic Materials, held $912.3 million in material assets as of March 2023 (total assets $1.3 billion), covering only 37.9% of projected military shortfalls in a base-case national emergency scenario.[1][2]

This stems directly from the DOD’s FY2023 Strategic and Critical Materials Biennial Report on Stockpile Requirements (submitted April 2023, inventories as of September 30, 2022), which modeled one year of combat plus three years of recovery and identified net shortfalls of $14.83 billion across 88 materials—$2.41 billion tied to military requirements for 69 materials and $12.21 billion for essential civilian demand.[1]

• The $13.5 billion overall gap is driven overwhelmingly by non-defense critical infrastructure needs; military coverage reaches only ~38% because private-sector procurement assumptions and limited NDS scale constrain the stockpile’s role.[1]
• No public FY2025 or FY2026 NDS requirements assessment or updated goals-versus-actual inventory has been released; the 2023 report remains the most recent comprehensive, congressionally submitted benchmark.[1]
• The NDS currently holds 54 commodities across 10 U.S. sites, but statutory limits prevent it from serving non-defense sectors outside declared emergencies.[3]

This structure means any competitor or new entrant must treat NDS data as a lagged, defense-only floor rather than a real-time market signal—private offtake agreements and DPA Title III funding become the practical bridge.

For the five queried materials, only germanium and antimony have quantifiable unclassified NDS holdings; gallium, graphite anodes, and NdFeB/SmCo permanent magnets show zero or negligible confirmed stockpiles in public records.[4][1]

Confirmed figures (as of late 2022 / September 2022 inventories):
- Germanium: 14,047 kg intrinsic metal + 6,905 kg scrap + 68,671 wafers—equivalent to roughly half a year of U.S. consumption at the time.[4][1]
- Antimony: 198,763 lb in inventory.[1]

• Gallium: No holdings reported; China’s export restrictions (imposed December 2024) explicitly block further accumulation.[4]
• Graphite (natural/synthetic anodes) and NdFeB/SmCo magnets: No specific NDS tonnages disclosed in unclassified inventories or the 2023 assessment.[4]

The mechanism is straightforward: byproduct recovery (zinc for germanium/gallium, bauxite for gallium) plus Chinese processing dominance leaves the NDS unable to scale without violating export bans or statutory civilian-use prohibitions—hence the documented half-year germanium coverage and complete gallium gap.

For anyone mapping supply risk, this means germanium is the only queried material with even partial buffer; the other four require immediate non-stockpile mitigations (domestic refining, allied offtake, or substitution).

In February 2026 the Trump administration launched Project Vault—a $12 billion public-private critical-minerals reserve backed by the largest EXIM Bank loan in its history plus $7.5 billion in congressional appropriations—explicitly to address the structural processing dependence the traditional NDS cannot solve.[5]

This initiative targets the full 60-mineral 2025 USGS Critical Minerals List (including the five queried here) and operates as an independently governed entity distinct from Pentagon-managed NDS stocks.[5]

• It responds to China’s 70%+ average refining share across 19 of 20 IEA-tracked strategic minerals and 100% import reliance for 12 critical minerals (USGS 2025 list).[5]
• Unlike the NDS, it includes equity stakes in mining/processing firms and is designed to build downstream capacity rather than merely warehouse raw material.[5]

The implication is that legacy NDS shortfalls are now being supplemented by a parallel, larger-scale mechanism; entrants should position for offtake or co-investment under Project Vault rather than waiting for NDS replenishment cycles.

Public 10-K risk-factor language and program specifications confirm critical-mineral exposure across all four named platforms, but no contractor filing or congressional testimony discloses exact kilogram or dollar shortfalls for gallium, germanium, antimony, graphite anodes, or NdFeB/SmCo magnets.[6]

• F-35 (Lockheed Martin): Lockheed’s filings note ongoing rare-earth supply-chain vulnerability; the APG-81 AESA radar relies on gallium-nitride semiconductors, while flight-control actuators and electric motors use NdFeB permanent magnets.[6]
• SM-6 / Patriot (RTX): Missile seekers, guidance electronics, and power systems incorporate rare-earth magnets and gallium-based components; RTX 10-Ks flag critical-material concentration risks but provide no quantities.[6]
• B-21 / F/A-18 (Northrop Grumman / Boeing): Stealth avionics, electronic-warfare suites, and electric systems depend on rare-earth magnets and gallium semiconductors; both contractors’ recent filings highlight REE and gallium import dependence without numeric exposure.[6]
• Virginia-class submarines: Electric-drive propulsion motors, sonar transducers, and periscope/actuator systems use NdFeB/SmCo magnets and specialized electronics containing germanium and gallium; General Dynamics and Huntington Ingalls 10-Ks reference supply-chain concentration but no specific shortfalls.[6]

No congressional testimony or public program office specification (e.g., Selected Acquisition Reports) states a dollar or tonnage gap for these exact materials in these platforms. All claims remain qualitative risk disclosures rather than quantified shortfalls.

Consequently, competitors cannot cite a verified “X tons short for F-35 Lot 18” figure; risk mitigation must rely on general 10-K language plus the 2023 NDS assessment’s aggregate $2.41 billion military shortfall.

The largest confirmed, citable gap remains the FY2023 assessment’s $2.41 billion military shortfall across 69 materials—explicitly including the queried minerals in the broader critical-materials list—while individual platform dependencies are acknowledged only at the risk-factor level in contractor filings.[1]

No later public document updates these figures or provides platform-specific quantities. New entrants or competitors should therefore treat the 2023 $2.41 billion military gap and the half-year germanium buffer as the sole hard, sourced benchmarks, supplementing with Project Vault participation and private refining investments rather than assuming updated NDS targets will close the delta.

Recent Findings Supplement (May 2026)

The U.S. government accelerated National Defense Stockpile (NDS) expansion in late 2025–early 2026 through new appropriations and procurement tools, but public disclosures still lack granular goal-versus-inventory figures for gallium, germanium, antimony, graphite anodes, or NdFeB/SmCo magnets.[1]

NDS Transaction Fund assets stood above $958 million before the One Big Beautiful Bill Act (signed 2025) added $2 billion; DoD announced intent in 2025 to procure up to $1 billion in materials, issuing RFIs for graphite, scandium, tungsten, samarium, dysprosium, terbium, bismuth, vanadium, and indium—quantities in several cases approached or exceeded annual U.S. consumption.[1]

DLA advanced some RFIs to sole-source IDIQ contracts or proposal evaluation, while R&D programs (SBIR/STTR focused on rare earths) expired September 30, 2025, requiring reauthorization.[1]

What this means for competitors: Domestic processors and miners with proven capacity for these exact minerals gain immediate access to large-scale, multi-year offtake; those without domestic refining face exclusion from NDS replenishment contracts.

DLA executed a $245 million, five-year sole-source IDIQ contract (announced December 2025) with United States Antimony Corporation for 3,026 metric tons of antimony metal ingots to replenish the NDS, followed by a separate $27 million Defense Production Act Title III award in February 2026 to expand Montana smelting capacity.[2]

A March 2026 $24.8 million DPA award went to Perpetua Resources for antimony development at its Stibnite project (the only U.S. site not controlled by China or Russia).[3]

No new public NDS inventory levels or shortfall dollar amounts for antimony (or gallium/germanium/graphite) appeared; RFIs and these contracts signal persistent gaps.[1]

What this means for competitors: Antimony suppliers with U.S. smelting assets secured multi-year revenue visibility; gallium and germanium projects without similar DPA backing remain at higher execution risk.

On February 2, 2026, the Trump Administration launched “Project Vault”—a $12 billion critical-minerals and rare-earth stockpile financed by a $10 billion, 15-year EXIM Bank loan plus $1.67 billion from private firms (including Boeing, GM, Stellantis, GE Vernosa, Google)—distinct from the defense-only NDS.[4]

Private participants sign purchase agreements at a fixed inventory price, cover carrying/storage costs, and gain access during disruptions; the NDS itself holds 37 materials valued at ~$1.152 billion.[4]

What this means for competitors: Commercial end-users (aerospace, autos, electronics) now have a parallel, non-defense stockpile mechanism; pure-play defense contractors gain indirect relief through broader market stabilization but must still meet NDS-specific sourcing rules.

A April 2026 engineering audit revised downward the long-cited 920-pound (417 kg) rare-earth figure for the F-35, labeling it unreliable (origin: unreleased 2012 DoD study critiqued by 2014 IG report); confirmed data show ~23 kg SmCo alloy (high-temperature actuators, lift fan) and estimated 8–20 kg NdFeB alloy plus minor yttrium, for total finished REE-bearing material of 40–70 kg and 11–20 kg pure elemental REEs per aircraft.[5]

Virginia-class (and Columbia-class) submarines, B-21 Raider, and Patriot/SM-6 systems are explicitly tied in 2026 contractor and Pentagon statements to rare-earth permanent magnets for propulsion, sonar, guidance, and avionics; Lockheed Martin’s January 2026 10-K (covering 2025) states it is actively securing “compliant” rare-earth mineral and magnet sources.[6]

No new program-specific shortfall quantities or dollar gaps were disclosed in public 10-Ks or testimony.[7]

What this means for competitors: Magnet and alloy manufacturers with non-Chinese, defense-qualified supply chains (especially SmCo for high-heat applications) hold pricing power on F-35 and submarine programs; NdFeB suppliers face stricter scrutiny on heavy-rare-earth content (dysprosium/terbium).

February 2026 Senate Armed Services testimony by DoD officials highlighted ongoing 100% foreign reliance for gallium (with a cited $29.9 million recovery award from alumina waste) and referenced export-control risks for germanium and rare-earth magnets; the FY 2027 President’s Budget requests $18.005 billion for the NDS plus nearly $13 billion across agencies for processing and pilot projects.[8]

No new GAO or CBO reports quantifying NDS goal-versus-actual gaps for the listed minerals were released after November 9, 2025.[9]

What this means for competitors: Firms positioned for gallium recovery, germanium recycling, or heavy-rare-earth magnet production can capture near-term DPA and NDS funding; unproven projects risk missing the FY 2027 budget cycle.

Overall, the most recent public record shows aggressive funding and contracting but continued opacity on exact inventory shortfalls; companies that convert RFI responses and DPA awards into domestic capacity for SmCo/NdFeB magnets, antimony ingots, and gallium/germanium recycling will capture the largest share of the announced $18+ billion in new resources.
