Which of the following is NOT one of the five MSC ship types?

• A. Combat Logistics
• B. Patrol Escort
• C. Prepositioning
• D. Sealift

Answer: (B)

MSC ship types are defined by their primary mission to support naval operations at sea—moving fuel, cargo, and equipment rather than engaging in frontline combat. Combat Logistics ships replenish a fleet at sea with fuel, ammunition, and supplies, keeping ships fueled and equipped during underway operations. Sealift ships carry general and heavy cargo to theaters, enabling theater sustainment. Prepositioning ships carry prepositioned equipment and supplies so forces can assemble rapidly without needing immediate port access. A separate category covers ships designed for specialized support missions and various auxiliary tasks that keep the fleet functioning.

Patrol Escort, in contrast, denotes a frontline combat-oriented role focused on patrolling and protecting ships, which falls outside these logistics-focused MSC categories. That’s why it’s not considered one of the MSC ship types.
