Although the failure to acquire an additional cruiser from the Americans was disappointing, Madrid still had much to be happy in the deal; after all, the deal was still an immense success. The 12 vessels, jointly of the Fletcher and Gearing classes, meant that Spain now had a modern destroyer force. Likewise, the acquisition of modernized Tench vessels conveyed upon Spain, for the first time ever, a capable submarine force. Both are critical for the Spanish Navy, as currently existing NATO estimates predict that the Soviet Navy will have among its ranks at least 300 attack submarines by 1960, posing a serious risk to NATO's sea-based connections of resupply and reinforcement between North America and Europe. Given Spain's commerce ties as well as the recognition from Madrid that reinforcements from the United States and Canada would be vital should the USSR attack into Western Europe, the new ships of the Navy allow Spain a fighting chance by presenting a true ASW force, with the submarines to be used in an hunter-killed manner.
The Mendez Nunez, the last ship of the Blas de Lezo-Cruiser class, as well as the three vessels of the Almirante Cervera-class are all decommissioned and slated for scrapping. The freeing of their complement, the funds gained from their scrapping and the upkeep costs saved from their removal allows for the Baltimore-class given from the Americans to receive her crew as well as enter port at Rota Naval Base in order for an extensive refit. The same is done for the new Destroyers and Submarines, in that the old and obsolete six B-class submarines, as well as the 15 ships of the Churruca-class of Destroyers and the three of Alsedo-class are to be scrapped. This allows for the trained personnel to transfer over to their new postings, while reducing the overall upkeep costs for the Navy in favor of fewer, but more modern and thus capable, vessels.
The Canarias, the only Spanish heavy cruiser in existence, is the only frontline vessel to be retained by the Armada Española from existing stocks. For now she will be the only heavy vessel in active service, as the new Baltimore-class vessel aforementioned upgrade will keep it from entering service for the new two years. To be named ESPS Arturo Espa, in recognition of a hero of the Cartagena uprising during the Civil War, the Spanish plans for the new cruiser call for the aft gun turrets and the aircraft catapult to be removed in favor of the installation of Terrier missile launchers as well as new radar systems for both the remaining guns, conventional AA, and the aforementioned missile systems. Some of the five inch guns are also slated to be removed:
The Arturo Espa will be a powerful ship, capable of excellent Anti Aircraft, Anti-Ship and Shore Bombardment duties.
