Which USNS ship type provides transportation for the Department of Defense and federal agencies?

The correct answer is Sealift Ships, which play a critical role in supporting military operations by transporting troops, equipment, and supplies on behalf of the Department of Defense and federal agencies. Sealift Ships are specifically designed to move large amounts of cargo, often including military vehicles and bulk supplies, across oceans in support of strategic deployments.

These vessels ensure that the United States military can rapidly respond to conflicts and humanitarian needs globally, providing the necessary logistical bridge to sustain operations effectively. They encompass various classes of ships, including those designed for roll-on/roll-off capability to facilitate the easy transfer of vehicles and cargo.

Combat Logistics Force Ships focus primarily on replenishing ships at sea, facilitating operations but not directly transporting personnel and material in the same strategic manner as Sealift Ships. Special Mission Ships serve specialized roles that support specific missions rather than general logistical transport. Prepositioning Ships have a unique mission to hold supplies ready for immediate use in crisis situations but do not primarily focus on transportation like Sealift Ships.
