Seems to me I remember this was quite a peice of technology to have been designed so long ago. Wouldn’t its plans had to have been drawn up in the 1890s?
It was launched in 1913. Lots of battleships were redesigned after the battle of Tsushima in 1905 and the launching of the HMS Dreadnought in 1906. What I found interesting when I toured the Texas a few years ago was that she had triple expansion steam reciprocating engines rather than steam turbines even thought the Dreadnought had steam turbines in 1906. This explains why the Texas was decommissioned immediately after WWII ended.
