The U.S. Navy’s Military Sealift Command is the premier provider of ocean transportation to the Department of Defense. The Command operates approximately 125 non-combatant, civilian-crewed ships that replenish U.S. Navy ships, conduct specialized missions, strategically preposition combat cargo at sea around the world and move military cargo and supplies used by deployed U.S. forces and coalition partners.
While they do play a critical role in support of the nation’s defense, their employees are not active duty members of the military. MSC civil service mariners (CIVMARs), the largest segment of their global workforce, are federal civil service employees.
All CIVMARs are employed by the Navy to serve MSC onboard naval auxiliaries and hybrid-manned warships worldwide, in peace and war. MSC exists to support the joint warfighter across the full spectrum of military operations. MSC provides on-time logistics, strategic sealift, as well as specialized missions anywhere in the world, in contested or uncontested environments.
