Which ship is designated as Mine Countermeasures Support Ship and has only one vessel in the naval inventory?

• A. Amphibious Warfare Ship (LHD)
• B. Mine Countermeasures Support Ship (MCS)
• C. Dock Landing Ship (LSD)
• D. Amphibious Assault Ship (LHA)

Answer: (B)

Understanding ship designations helps you match a ship’s role to its name. A Mine Countermeasures Support Ship is a dedicated platform whose entire purpose is to support mine countermeasures operations—providing logistics, maintenance, and command-and-control resources to the mine warfare teams during operations. That designation is distinctive for its purpose and, in this context, is noted as having only one vessel in the inventory. The other options describe amphibious and landing ships, which are multi-ship classes with different missions (carrying troops, vehicles, and landing them ashore) and thus do not carry the Mine Countermeasures Support designation. So the designation that aligns with a single-ship Mine Countermeasures Support role is the Mine Countermeasures Support Ship itself.
