List of tinclad warships of the Union Navy
From Wikipedia, the free encyclopedia
Vessels converted from civilian steamboats by arming them, adding a wooden casemate, and armoring portions of the vessel, were referred to as tinclad warships. The Union Navy used tinclad warships during the American Civil War, mostly converted civilian ships, although a few were purpose-built for the United States War Department; some had formerly been in Confederate service. Tinclads were cheaper, required smaller crews, and could enter shallower water than ironclad warships due to their light drafts. While tinclads were poorly suited to engage heavy artillery or other warships, they were better equipped to combat small groups of enemy soldiers. Tinclads were frequently used for escort and patrol duties, and sometimes provided naval support for other military actions. A total of 74 saw service during the war.
