OCS Naval History Practice Test

The hull classification symbol CVN denotes:

Carrier, non-nuclear Aircraft carrier, nuclear-powered Combat Vessel, Naval Civilian vessel, naval

Correct Answer:

Combat Vessel, Naval

Explanation:

Understanding hull classification symbols means reading the letters as a type plus propulsion. CV designates an aircraft carrier, and the suffix N shows nuclear propulsion. So CVN means an aircraft carrier powered by a nuclear reactor. This distinguishes it from older, non‑nuclear carriers (which would be CV) and from non-standard labels like “combat vessel” or “civilian vessel,” which aren’t used to describe Navy ships. Modern nuclear-powered carriers, such as the large fleet carriers, use this CVN designation.
