Impact of the Strait of Hormuz Closure on U.S. Defense Readiness

The closure of the Strait of Hormuz has led to significant disruptions in the supply chains critical to the U.S. defense industrial base. According to an analysis by the Modern War Institute at West Point, the strait is pivotal for the transportation of sulphur, a vital input for extracting essential minerals such as copper and cobalt. These minerals are crucial for manufacturing and repairing military equipment. The report highlights that sulphur prices have surged nearly 25% since the onset of the conflict, with a staggering 165% increase year-on-year. This disruption poses a "paralyzing, real-time problem" for U.S. defense readiness, as the availability of these minerals directly impacts the speed and efficiency of military production.

The Modern War Institute's analysis underscores the importance of copper, which is embedded in various military technologies, including transformers and communication hardware. The report estimates that over 30,000 kilograms of copper will be required to replace two major U.S. radars destroyed in Bahrain and Qatar, alongside additional quantities needed for other damaged equipment across the Middle East. This situation has evolved into what the authors describe as a "prelogistical crisis," where military planning has historically overlooked the significance of these supply chain vulnerabilities.

Lieutenant Colonel Jahara “Franky” Matisek, one of the report's authors, points out that only 6% of U.S. defense contractors maintain fully transparent supply chains. This lack of visibility has resulted in a military effort constrained by upstream conditions that are beyond its control. Matisek emphasizes the need for greater transparency, stating, “We can’t actually allow them to do that any more because we actually need to know this.” The complexity of the supply chain, compounded by proprietary information held by large defense contractors, has created a situation where military planners are unaware of the sources of critical materials.

The implications of the sulphur and copper shortages extend beyond military readiness. The disruption in sulphur supply, primarily produced as a byproduct of crude oil refining in the Middle East, also threatens agricultural sectors reliant on sulphur for fertilizers. This could have downstream effects on food supplies, particularly in low-income countries that compete in the same markets as wealthier nations.

The U.S. Department of Defense has been approached for comments regarding these supply chain challenges, but no official response has been reported as of yet. The urgency of the situation is underscored by Matisek's warning about the potential for increased costs and delays in military replenishment due to these mineral shortages.

While the analysis presents a clear picture of the challenges facing U.S. defense readiness, it lacks specific details on how the Department of Defense plans to address these supply chain issues. Additionally, there is no information on whether any measures have been implemented to increase production or secure alternative sources for these critical minerals.
