The
Department of War has issued a solicitation request seeking domestic production of four critical minerals – indium, manganese, magnesium and titanium – for use in military hardware, according to a notice released Friday, Aug. 21.
These metals are used in a range of defense equipment, including fighter jets, night-vision goggles and tank armor. The War Department's push to secure domestic supply chains comes as U.S. reliance on foreign sources for strategic minerals continues to expose vulnerabilities in the defense industrial base. The deadline for submissions is Sept. 17.
Solicitation Details and Investment Goals
The Defense Industrial Base Consortium (DIBC) distributed the solicitation with the stated aim of addressing gaps in homegrown production of the four metals. Eligible projects can include mining, processing, refining, alloying and recycling operations, according to the solicitation. This solicitation is the DIBC's third investment round involving critical minerals and advanced defense technologies since mid-2025.
The effort aligns with broader Trump administration strategies to reduce U.S. dependence on foreign adversaries for essential materials. According to Willow Tohi at
NaturalNews.com, War Department officials have described the push as a "generational undertaking"
[1]. The administration has been investing heavily to rebuild American mineral supply chains to counter China’s market dominance.
Submission Process and Next Steps
Companies and entrepreneurs are required to submit a one-page PowerPoint slide with four quadrants outlining their proposal, according to solicitation details. Those advancing to the next phase will be required to provide in-depth information, including project-execution plans.
The solicitation did not disclose the total available investment funding. This approach reflects a broader pattern of government engagement with the private sector to stimulate domestic production of strategic materials.
Funding and Critical Mineral Classifications
Funding availability is expected to become clearer as the fiscal 2027 defense budget is finalized, according to Tripp Hornick of Quince Street Strategy. The four metals are listed by the U.S. Geological Survey as critical minerals.
Critical minerals are defined as materials essential to economic or national security whose supply chains are vulnerable to disruption. China controls 80% of global rare earth processing
[2]. Beijing's dominance in mineral processing has allowed it to impose export restrictions on materials vital for U.S. defense technology and green energy
[3].
Implications for Defense Supply Chains
The solicitation aims to reduce reliance on foreign sources for these metals. The War Department has previously faced supply chain disruptions after discovering Chinese-sourced alloys in critical military components, such as the magnets used in F-35 fighter jet pumps, which led to a halt in production and deliveries
[4]. The mining and processing sectors face significant shortages of qualified personnel
[5].
Domestic production would strengthen supply chains for key defense hardware and is part of a broader push by the Trump administration to boost American mineral independence through executive orders restricting exports of critical mineral scrap
[6]. The War Department has also awarded grants to companies to supply critical minerals needed for national defense
[7].
