美国国防部国防工业基地联盟（DIBC）正在向本土金属制造商征求投资提案，以填补铟、锰、镁和钛等关键矿物的生产缺口。这些金属对制造战斗机、夜视镜和坦克装甲等军事装备至关重要。

提案截止日期为9月17日，符合条件的专案涵盖从采矿、加工到合金化和回收的整个供应链。申请者首先需提交一页包含四个象限的简报，通过初步审核后才需要提供更详细的专案执行计划。

目前的招募文件并未透露确切的投资融资金额，预计在2027财年国防预算定案后会更加明朗。这四种金属被美国地质调查局列为关键矿物，这意味著它们对经济或国家安全极具重要性，且供应链容易受到干扰。

The US Defense Department’s Defense Industrial Base Consortium (DIBC) is seeking investment pitches from domestic metal producers to address production gaps in indium, manganese, magnesium, and titanium. These metals are critical for manufacturing military equipment such as fighter jets, night-vision goggles, and tank armor.

The submission deadline is September 17, and eligible projects cover the entire supply chain from mining and processing to alloying and recycling. Applicants must initially submit a one-page, four-quadrant PowerPoint slide, with more detailed execution plans required for those who advance to the next phase.

The exact amount of investment funding available has not been disclosed and is expected to become clearer once the fiscal 2027 defense budget is finalized. These four metals are designated as critical minerals by the US Geological Survey, highlighting their essential role in economic and national security, as well as their vulnerable supply chains.
