Military sealift commands

• Origins in World War II: Military Sealift Command (MSC) traces its roots to the Naval Transportation Service and Army Transport Service, which were vital for Allied logistics during World War II. • Official Formation: MSC was formally established on July 1, 1949, consolidating several transportation functions under one command for efficiency. • Civilian Mariners: Unlike other U.S. Navy units, the majority of MSC ships are operated by civilian mariners known as "CIVMARS," not active-duty military personnel. • Global Reach: MSC operates nearly 125 ships worldwide at any given time, providing logistical support wherever U.S. forces are deployed. • Underway Replenishment: MSC ships are responsible for underway replenishment, delivering fuel, ammunition, and supplies to Navy ships at sea, allowing them to remain on station longer. • Vital in Conflicts: MSC played crucial roles in the Korean War, Vietnam War, Operation Desert Storm, and the wars in Iraq and Afghanistan, transporting troops, equipment, and supplies. • Fast Sealift Ships: MSC operates some of the world’s fastest cargo ships, capable of speeds up to 33 knots, used for rapid deployment of military equipment in emergencies. • Humanitarian Missions: MSC ships regularly participate in humanitarian efforts, such as delivering disaster relief supplies after hurricanes, earthquakes, or tsunamis. • Prepositioning Program: MSC manages prepositioned ships loaded with military equipment and supplies, stationed around the world for rapid response to crises. • "Blue and Gold" Crew Concept: Some MSC ships use a dual crew system—Blue and Gold crews—that rotate to maximize operational availability and reduce crew fatigue.
