Which class resembles destroyers in appearance but is slower, has only one screw, and carries less armament?

• A. Destroyer/Guided Missile Destroyer (DD/DDG)
• B. Guided Missile Frigates (FFG)
• C. Carrier/Nuclear Powered Carrier (CV/CVN)
• D. Amphibious Command Ship (LCC)

Answer: (B)

Recognizing ship classes by propulsion and armament helps you identify their roles. Destroyers are fast, heavily armed escort ships, typically designed for multi-mission tasks and usually powered by more than one propeller. If a vessel looks like a destroyer in size and silhouette but is slower, has a single propeller (one screw), and carries fewer weapons, it fits the profile of a guided missile frigate. Frigates provide escort and patrol capabilities with missiles but don’t match a destroyer’s speed or breadth of armament. The other options describe ships with clearly different roles and propulsion or hull characteristics: carriers and amphibious command ships are much larger with different mission profiles. So the description points to a guided missile frigate.
