The Columbia-class submarines represent a significant advancement in American nuclear deterrence, intended to replace the aging Ohio-class fleet. These new submarines are expected to enter service in the 2030s and 2040s.
Each Columbia-class submarine will be equipped with 16 Trident II missiles, enhancing the Navy's strategic capabilities. However, their reliance on rare earth elements raises concerns about supply chain vulnerabilities.
As the Navy prepares for this transition, it is crucial to address the implications of these dependencies to ensure the effectiveness and reliability of the new fleet.
