HMS Nelson. One of the more curious, no, the most curious Battleship classes (2) ever built.
The first thing that comes to mind is "Shipmate, where is your stern?" If it looks like a ship built by committee, well that is because it is.
A product of The Washington Treaty, "compromises" were made. Though it was the only RN ship with 16" guns, the ship herself was a tad slow, and once the war was done - like the rest of the RN Battleships - off to the breakers she went.
Best pictures here. Other sites here and here.
It is not correct to say that Nelson was the only RN ship to carry 16" guns; her sister-ship Rodney did also. Rodney did much of the heavy lifting in the final destruction of the Bismarck.
