Guns in a turret

The USS Monitor concentrated her whole battery in a single revolving armored turret: two heavy 11-inch Dahlgren smoothbore shell guns. Because the turret turned, the guns could be trained on a target without maneuvering the low, raftlike hull.

This arrangement, joining heavy guns, armor, and a turning turret, met the Virginia in Hampton Roads in the famous first duel of ironclads and pointed the way to the future of naval ordnance.
