The biggest civil war ironclad was the USS Monitor, notable for its revolutionary design and its clash with the CSS Virginia at the Battle of Hampton Roads in 1862. However, the largest ironclad in terms of size was the USS New Ironsides, which was equipped with heavy armor and powerful guns, serving effectively in the Union Navy. While both ships played significant roles in naval warfare during the Civil War, the New Ironsides was larger and heavily armed compared to the Monitor.
The ships in the Civil War were called the Ironclad.
