CSS Missouri
CSS ''Missouri'' was a Confederate States Navy casemate ironclad paddle steamer deployed on the Red River during the American Civil War. For most of the war she was trapped in the Shreveport, Louisiana area by low water on the Red River. The ship was surrendered in June 1865 to the United States Navy and sold in November.
==Description==
''Missouri'' was long overall, had a beam of and a draft of . Her casemate extended for most of the length of the ship and was long. It partially enclosed her diameter center paddle wheel in a recess at the aft end of the casemate; the upper of the paddle wheel protruded above the casemate and was totally unprotected.〔Official Records, pp. 241–42〕 The stern wheel was powered by two steam engines taken from the steamboat ''Grand Era'';〔Silverstone, p. 153〕 four boilers provided steam to the engines and were connected to a single funnel.〔Still, p. 148〕 The ship had a maximum speed of .〔
''Missouri''s armor consisted of railroad "T-rails", laid alternately with the crowns up and down. They were spiked to the backing of of yellow pine, but not closely together enough to give them a solid surface. On the sides of the ship, they were laid diagonally, but were vertical on the bow and stern faces of the casemate. The armor extended approximately below the waterline. The casemate was sloped at an angle of 30°. The deck fore and aft of the casemate was also protected by "T-rails". At the forward end of the casemate was a pilothouse that was raised above the deck.〔Official Records, p. 241〕 She was built of green timber, caulked with cotton and leaked like a sieve. Despite her three rudders, her stern wheel made her difficult to steer.〔Still, pp. 148–49〕
The casemate had eight gun ports, two in the bow face and three on each side, although only three guns were mounted in the ship. A smoothbore Dahlgren pivot gun was mounted in the starboard forward position. It could fire out of the starboard bow port or the forward starboard broadside port.〔Official Records, p. 242〕 It weighed approximately and could fire a shell up to a range of at an elevation of 15°.〔Olmsted, et al., p. 90〕 An old 32-pounder (14.5 kg) siege gun was in the equivalent position on the port side of the ship. The characteristics of this gun cannot be reliably determined because the United States produced a multitude of 32-pounder guns before the Civil War, but none of them were designated as siege guns.〔Olmsted, et al., pp. 7–59〕 The third gun was a smoothbore Dahlgren pivot gun that could fire out of either of the two aft broadside gun ports. It weighed approximately and could fire a shell up to a range of at an elevation of 15°.〔Olmsted, et al., p. 87〕
