What ships were used by the Union during the American Civil War?

• A. Ironclads
• B. Galleons
• C. Double-enders
• D. Caravels

Answer: (C)

The main idea here is that Civil War naval warfare was defined by ironclads—armor-plated, steam-powered ships. The Union deployed ironclads to break the Confederacy’s blockade and to outgun traditional wooden vessels, with the famous Monitor-Merrimack encounter epitomizing this shift in naval technology. Galleons and caravels are from much earlier centuries and weren’t part of Civil War fleets. Double-enders describe a ship design that can be fought from either end, a concept that existed in various forms but isn’t what the Union’s naval force is best known for in this war. So, understanding that ironclads were the defining ships helps explain why they’re the best answer.
