Blas de Lezo-class cruiser

The Blas de Lezo-class cruisers were a group of two cruisers built for the Spanish Navy in the 1920s. The ships were ordered in 1915 but construction proceeded slowly due to materials shortages during World War I. The ships were built by Sociedad Española de Construcción Naval in Ferrol and showed considerable British design influence, resembling contemporary British C-class cruisers.

Blaz de Lezo

Blas de Lezo was named after Admiral Blas de Lezo. In early 1926, she supported the transatlantic flight from Spain to Buenos Aires, Argentina, of a four-man Spanish Air Force crew led by pilot Major Ramón Franco – the brother of future Spanish caudillo Francisco Franco – and including copilot/navigator Captain Julio Ruiz de Alda Miqueleiz in the Dornier Do J Wal ("Whale") flying boat Plus Ultra ("Farther Still"), carrying spares and other equipment for the flight.[1] She struck a rock near Cape Finisterre in 1932 and sank in deep water.

Mendez Nunez

Mendez Nunez was named after Admiral Casto Méndez Núñez. She was based in Equatorial Guinea at the start of the Spanish Civil War and she returned home to fight for the Spanish Republican Navy. In 1939, following the Cartagena Uprising, she was interned in Bizerte and seized by the French authorities. She was later handed to Francoist Spain, serving until 1963.
