Ironclad

An ironclad was a type of 19th century sailing ship, best described as a warship clad with iron-plated armor. This type of vessel was predominantly used on Earth during the American Civil War by both the Union and Confederate Armies.

Images depicting several ironclads of this era were scanned by the Talosians, while they downloaded the USS Enterprise (NCC-1701)'s library computer in 2254. ( and "The Cage" remastered)
