Mission
As a global Type Commander (TYCOM) and Navy Component Commander to U.S. Transportation Command (USTRANSCOM), MSC provides combat logistics, special mission, service support, and strategic sealift to deploy and sustain U.S. Forces worldwide, during peacetime and war.
EXECUTIVE SUMMARY
As the Department of War’s maritime logistics provider, Military Sealift Command (MSC) delivers agile, persistent, and innovative sealift logistics solutions to the Navy and Joint Force, generating effects across the spectrum of military operations in strategic competition, crisis, and conflict.
MSC crews, trains, equips, and operates more than 140 government and commercially-owned and chartered vessels to directly support Navy Fleet Commanders. MSC, as Naval Sealift Transportation Command (NAVTRANS), also serves as the Naval Component of U.S. Transportation Command (USTRANSCOM).
The MSC Fleet includes cargo vessels, tankers, naval auxiliaries, and a variety of special mission ships. MSC ships are underway around the world to serve joint warfighters and call on ports in every continent, including Antarctica.
MSC Area Commands provide expertise and operational perspective to Navy Fleet Commanders worldwide. The Area Commands are operationally focused and aligned with the Numbered Fleet logistics staffs in their respective theaters: MSC Atlantic in Norfolk, Virginia; MSC Pacific in San Diego; MSC Europe and Africa in Naples, Italy; MSC Central in Manama, Bahrain; and MSC Far East in Singapore. The MSC Area Commands also directly command and control vessels assigned USTRANSCOM missions as part of the NAVTRANS mission.
Ship maintenance and support functions are integrated into six maintenance hubs under the Area Commands in the following locations: Naples, Italy; Manama, Bahrain; Singapore; Yokohama, Japan; San Diego and Guam.
MSC is a $5 billion per year organization which provides services to the Navy, Army, Air Force, Marine Corps, Coast Guard, Space Force, U.S. Transportation Command, Missile Defense Agency, and other U.S. government agencies.
Worldwide operations are funded through two working capital funds, complemented by Navy’s Operations and Maintenance funding to support Maintenance and Repair. The Navy Working Capital Fund is used to support Navy Fleet Commanders and other Department of War entities. The Transportation Working Capital Fund is used to support sealift services.
MSC receives direct funding appropriations from the Navy for Maintenance and Repair. MSC customers transfer funding for their requirements to MSC into the appropriate working capital fund and MSC draws from the fund to pay for command operations. Essentially, MSC is primarily funded by purchases from its customers.
Unlike private industry, that budgets to make a profit, the goal of the Working Capital Fund is to break even, i.e., charges levied on customers equal MSC’s expenses and no more.
Created in 1949, MSC, then called Military Sea Transportation Service, became the single managing agency for the Department of War’s ocean transportation needs. MSC has been present during every major conflict since World War II, providing vital logistics and operational support to the U.S. Navy and Joint Force around the globe.
MSC is focused on continuing to achieve maritime success in a contested logistics environment by developing new technologies and strategies. The next decade will see the delivery of new ships with modernized systems, and emerging capabilities such as new ship to shore connectors, unmanned resupply, and expeditionary munitions reload to better support distributed maritime logistics and no-fail mission sustainment.
