Pentagon war game simulations last summer exposed a critical vulnerability in the US aluminum supply chain, months before Iran-linked attacks. The drill, involving 80 government and industry officials, tested resilience against disruptions like drone damage to facilities. A key focus was Arconic's role in producing ultra-refined aluminum for military use, which saw tight supplies after a UAE plant was hit. The scenario highlighted risks to defense operations and the need for rapid domestic production scaling. UAE and Iran attacks underscored geopolitical threats to this strategic commodity.

The article from Bloomberg Markets notes that aluminum shortages could cripple fighter jet production. Officials emphasized coordination between defense sectors and industrial leaders to mitigate such risks. The Iran attacks later confirmed the urgency of these findings, as global supply chains faced immediate strain. Arconic’s Tennessee facility, a major producer, became a focal point for securing reserves.

Experts warn that reliance on foreign-aluminum sources remains a looming threat. The war game’s findings stress the importance of diversifying suppliers and bolstering local manufacturing. Without proactive measures, similar disruptions could repeat, endangering military readiness and civilian industries reliant on aluminum.

This critical risk remains unresolved, with no immediate solutions proposed. The UAE incident serves as a real-world test of preparedness, demonstrating how swiftly supply chains can fracture under conflict or cyberattacks.
