The splendid looking Russian Battleship, called the Retvizan was sunk in action during the Russian Japanese War in 1904.
The dry dock at the Brooklyn Navy Yard was used by many navies to have their hulls cleaned and maintenance done. The Retvizan was not really a battleship it was more of a pre dreadnought battle cruiser.
But it was the precursor to the new navy. But what was in front of this ship in 1900 was what was going to be the major part of every ones navy in a few years. The incredible submarine.
