USS Monitor was an ironclad warship built for the United States Navy during the American Civil War and completed in early 1862, the first such ship commissioned by the Navy. [a] Monitor played a central role in the Battle of Hampton Roads on 9 March under the command of Lieutenant John L. Worden, where she fought the casemate ironclad CSS Virginia (built on the hull of the scuttled steam ...
Naval architect and engineer John Ericsson designed the Passaic-class warships, drawing upon lessons learned from the first USS Monitor, which he also designed. The Passaic monitors were larger than the original Monitor and had their pilothouses atop the turret, rather than near the bow. This allowed a wider field of view and easier ...
Turret of USS Monitor. Including the guns, the turret weighed approximately 160 long tons (179 short tons; 163 t); the entire weight rested on an iron spindle that had to be jacked up using a wedge before the turret was free to rotate. [8]
The whole category of monitors took its name from the first of these, USS Monitor, designed in 1861 by John Ericsson. They were low-freeboard, steam-powered ironclad vessels, with one or two rotating armored turrets, rather than the traditional broadside of guns. The low freeboard meant that these ships were unsuitable for ocean-going duties ...
USS Monitor, the first monitor (1861) HMS Marshal Ney used a surplus 15-inch gun battleship turret. A monitor is a relatively small warship that is neither fast nor strongly armored but carries disproportionately large guns. They were used by some navies from the 1860s, during the First World War and with limited use in the Second World War ...
The armor of the gun turret, of 21 ft (6 m) internal diameter, and the pilot house consisted of ten layers of one-inch plates. The ship's deck was protected by armor 1.5 inches (38 mm) thick. A 5-by-15-inch (130 by 380 mm) soft iron band was fitted around the base of the turret to prevent shells and fragments from jamming the turret as had ...
The ships' main armament consisted of four smoothbore, muzzle-loading, 15-inch (381 mm) Dahlgren guns mounted in two twin-gun turrets. [2] Each gun weighed approximately 43,000 pounds (20,000 kg). They could fire a 350-pound (158.8 kg) shell up to a range of 2,100 yards (1,900 m) at an elevation of +7°. [ 5 ]
The turrets, with 11 inches (280 mm) of an armor, [1] were similar to the turrets on the Passaic class, only slightly larger. There were pilothouses fitted on the top of each turret. A light hurricane deck was constructed between the turrets, along with a tall funnel and a tall ventilation shaft. There were some variations within the class ...
