Question: Which 20th century battleship featured artillery with a specially reinforced barrel and steam turbine propulsion?

 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. A built-up gun is artillery with a specially reinforced 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. <SEP>  "Dreadnought"' s design had two revolutionary features: an "all-big-gun" armament scheme, with more heavy-calibre guns than previous ships, and steam turbine propulsion. The dreadnought was the predominant type of battleship in the early 20th century.  The first of its kind, the Royal Navy's "Dreadnought" , made such a strong impression on people's minds when launched in 1906 that similar battleships built subsequently were referred to generically as "dreadnoughts", and earlier battleships became known as "pre-dreadnoughts".  As dreadnoughts became a symbol of national power, the arrival of these new warships was a crucial catalyst in the intensifying naval arms race between the United Kingdom and Germany.  With the launch of a single ship, "Dreadnought", the scales of naval power were reset overnight.  As a result, dreadnought races sprang up around the world, including in South America, during the lead up to World War I.  Successive designs increased rapidly in size and made use of improvements in armament, armour, and propulsion throughout the dreadnought era.  Within five years, new battleships had outclassed "Dreadnought".  These more powerful vessels were known as "super-dreadnoughts".  Most of the original dreadnoughts were scrapped after the end of World War I under the terms of the Washington Naval Treaty, but many of the newer super-dreadnoughts continued to be used throughout World War II.  The only surviving dreadnought is USS "Texas" , located near the San Jacinto Battleground State Historic Site. <SEP> Steam-powered vessels include steamboats and steamships.  Smaller steamboats were developed first.  They were replaced by larger steamships which were often ocean-going.  Steamships required a change in propulsion technology from sail to paddlewheel to screw to steam turbines.  The latter innovation changed the design of vessels to one that could move faster through the water.  Engine propulsion changed to Steam turbine in the early 20th century.  In the latter part of the 20th century, these, in turn, were replaced by gas turbines. <SEP> The Mark 10 torpedo was a torpedo put into use by the United States in 1915.  It was derived from the Mark 9 aircraft torpedo converted to submarine use.  It was used as the primary torpedo in the R- and S-class submarines.  It used alcohol-water steam turbine propulsion.  It was succeeded by the problematic Mark 14 torpedo, but remained in service in S-boats & fleet submarines through the Pacific War.  The Mark 10 featured the largest warhead (497 lb of TNT) of any U.S. torpedo developed at that time.  Stockpiles of Mark 10 Mod 3 torpedoes were used extensively during the first part of World War II due to short supply of the newer and longer (246 in Mark 14s, with some fleet submarines carrying a mixture of both types on patrol.
