Which 20th century battleship featured artillery with a specially reinforced barrel and steam turbine propulsion?
Built-up gun A built-up gun is artillery with a specially reinforced barrel. An inner tube of metal stretches within its elastic limit under the pressure of confined powder gases to transmit stress to outer cylinders that are under tension. Concentric metal cylinders or wire windings are assembled to minimize the weight required to resist the pressure of powder gases pushing a projectile out of the barrel. Built-up construction was the norm for guns mounted aboard 20th century Dreadnoughts and contemporary railway guns, coastal artillery, and siege guns through World War II.
Russian battleship Rostislav Rostislav was a pre-dreadnought battleship built by the Nikolaev Admiralty Shipyard in the 1890s for the Black Sea Fleet of the Imperial Russian Navy. She was conceived as a small, inexpensive coastal defence ship, but the Navy abandoned the concept in favor of a compact, seagoing battleship with a displacement of 8880 LT . Poor design and construction practices increased her actual displacement by more than 1600 LT . "Rostislav" became the world's first capital ship to burn fuel oil, rather than coal. Her combat ability was compromised by the use of 10 in main guns instead of the de facto Russian standard of 12 in .
