What is the only surviving WWI dreadnought class battleship?

Among the world's remaining battleships, Texas is notable for being the only remaining WW1 era dreadnought battleship, though she is not the oldest surviving battleship: Mikasa, a pre-dreadnought battleship ordered in 1898 by the Empire of Japan, and HMS Victory, launched 1765, are both older than Texas. She is also noteworthy for being one of only six remaining ships to have served in both World Wars. Among US-built battleships, Texas is notable for her sizable number of firsts: the first US Navy vessel to house a permanently-assigned contingent of US Marines, the first US battleship to mount anti-aircraft guns, the first US ship to control gunfire with directors and range-keepers, the first US battleship to launch an aircraft, from a platform on Turret 2, one of the first to receive the CXAM-1 version of CXAM production radar in the US Navy, the first US battleship to become a permanent museum ship, and the first battleship declared to be a US National Historic Landmark.
