In addition to the logistics concerns surrounding charging EVs, Marine Corps Systems Command points to another issue they consider prohibitive: the amphibious service’s tactical vehicles all have a built-in requirement to be able to drive through small bodies of water at depths of up to 60 inches, or five feet. While commercially available EVs — without exhaust pipes or air intakes — have demonstrated the ability to drive through standing water without issue, there have also been instances of EVs catching fire in floodwaters due to “thermal runaway” following battery damage.
