Pelayo was a battleship of the Spanish Navy which served in the Spanish fleet from 1888 to 1925. She was the first battleship and the most powerful unit of the Spanish Navy at the time. Despite its modern design for the time, Pelayo and the rest of the Spanish Asia-Pacific Rescue Squadron never engaged in combat during the Spanish–American War. Some historians have argued that had the battleship, along with the modern armored cruiser Carlos V, participated directly in the conflict the course of the war would have been altered dramatically and possibly lead to a Spanish victory, thus retaining Spain's status as a colonial power.

Emperador Carlos V was an armored cruiser of the Spanish Navy which served in the Spanish fleet from 1898 to 1933. The money intended to build torpedo boats was used to build a 9,000-ton cruiser, deriving this cruiser from the British Blake class. Said cruiser stood out for its great autonomy, while it suffered from having little armor, mounting only during its first days of life 4 pieces of García Lomas of 100 mm.
