Military sealift commands

The Military Sealift Command (MSC) is a United States Navy organization established in 1949 to provide ocean transportation of equipment, fuel, supplies, and ammunition to sustain U.S. military forces worldwide. Originally formed as the Military Sea Transportation Service (MSTS), the MSC has evolved to manage a fleet of civilian-crewed ships that perform essential logistics, special mission, and prepositioning operations. Throughout major conflicts such as the Korean War, Vietnam War, Gulf War, and recent operations in the Middle East, MSC vessels have delivered critical cargo and supported naval operations. Today, the MSC remains a vital component of U.S. military readiness, ensuring rapid and efficient global sealift capability.
