Espana was the lead ship of the only class of Spanish dreadnought battleships. These were small dreadnoughts, armed with eight 12-inch gunsm, in twin turrets fore and aft, and en echelon to port and starboard. Typical of battleships of this period, they had minimal superstructures - only a small bridge forward, and two tripod masts.

The three ships of this class seem to have been unlucky. Espana ran onto an uncharted reef of Morocco on 26 August 1923, and became a total loss as seen here. In this view the hull is broken into two pieces, and the armament has been salvaged. The bow section, with the forward barbette, bridge, and foremast, is seen at the bottom of the photo. The aft section of the hull shows the two midships barbettes, the aft barbette, and the main mast.

Of the other ships in the class, Alfonso XIII was renamed Espana in 1931; she was taken over by the Nationalists during the Spanish civil war, but drifted onto a Nationalist mine and sank. The final ship, Jaime I, caught fire while under repair and became a total loss.
