What was the major naval base for logistic support during the Vietnam operations?

Subic Bay in the Philippines served as the major naval base for logistic support during the Vietnam operations. Its strategic location was ideal for facilitating operations in Southeast Asia, providing a pivotal point for the U.S. Navy to replenish ships and support ongoing military efforts. The base had extensive facilities that accommodated large numbers of fleet personnel and offered repair, maintenance, and resupply services, which were crucial during the extensive naval operations of the Vietnam War. Additionally, Subic Bay's proximity to Vietnam allowed for quick deployment and support of naval forces engaged in various operations throughout the conflict.

While other locations like Guam, Hawaii, and Yokosuka played roles in the U.S. military's larger operational strategy, they did not serve the same level of logistical support specifically for Vietnam operations as Subic Bay. Guam and Hawaii were used for broader strategic purposes, and Yokosuka primarily functioned as a base for U.S. naval operations in Japan, rather than being directly involved in the Vietnam campaign.
