España-class battleship

The ''España'' class was a series of three dreadnought battleships that were built for the Spanish Navy between 1909 and 1921: , , and . The ships were ordered as part of an informal mutual defense agreement with Britain and France, and were built with British support. The construction of the ships, particularly the third vessel, was significantly delayed by shortages of materiel supplied by the UK during World War I, particularly armaments; ''Jaime I'' was almost complete in May 1915 but her guns were not delivered until 1919. The ships were the only dreadnoughts completed by Spain and were the smallest of the type built by any country. The class's limited displacement was necessitated by the constraints imposed by the weak Spanish economy and existing naval infrastructure, requiring compromises on armor and speed to incorporate a main battery of eight guns.

''España'' represented Spain during the opening of the Panama Canal in 1915 and conducted training exercises with ''Alfonso XIII'' after she entered service later that year. Both ships conducted long-range voyages to North and South America in 1920–1921; ''España'' was damaged in an accidental grounding off the coast of Chile. Both vessels provided gunfire support to ground forces engaged in the Rif War, which started in mid-1921, and ''Jaime I'' joined them there after her commissioning later that year. In 1923, ''España'' ran hard aground off Cape Tres Forcas while bombarding Rif positions and could not be freed before storm damage destroyed the ship in November 1924. Some of her guns were salvaged and later used as coastal artillery in Spain. The two surviving ships of the class supported the landing at Alhucemas, where ''Alfonso XIII'' served as the flagship.

After King Alfonso XIII was deposed and the Second Spanish Republic was proclaimed in 1931, ''Alfonso XIII'' was renamed ''España'' and both members of the class were reduced to reserve to reduce costs. ''Jaime I'' returned to service for use as the fleet flagship in 1933. Plans to modernize the ships in the mid-1930s were interrupted by the start of the Spanish Civil War. ''España'' was seized by the rebel Nationalist faction at the start of the conflict while the Republican government retained control over ''Jaime I''. ''España'' was used to enforce a blockade of Republican-controlled ports in northern Spain; the Spanish Republican Navy briefly deployed ''Jaime I'' to break the blockade but neither side attacked the other. ''España'' was lost after striking a mine in April 1937, though almost her entire crew was saved. ''Jaime I'' was attacked by German and Italian bombers during the war before being destroyed by an accidental explosion in June 1937. Guns from ''Jaime I'' were recovered and used for coastal batteries.

Background

The Spanish public blamed the Navy for the country's disastrous losses in the Spanish–American War of 1898 but recognized the need to modernize and rebuild it. The first attempt to rebuild the Navy came in the Fleet Plan of 1903, which called for a fleet centered on seven battleships and three cruisers. This plan proved to be too ambitious for the weak Spanish economy and an unstable Spanish parliament was unable to provide funding. The Fleet Plan of 1905 proposed a fleet of eight battleships, a number of torpedo boats, and submarines; this plan also fell victim to the weaknesses of the Spanish government and a lack of public support. International developments, particularly conflicts with Germany in the First Moroccan Crisis, provided the impetus and public support necessary for the Spanish government to embark on a major naval construction program.

In April 1904, Britain and France reached the ''Entente Cordiale'', putting aside their traditional rivalry to oppose German expansionism. The agreement directly affected Spain because it settled matters of control over Morocco and placed Tangier under joint British–French–Spanish control. The agreement brought Spain closer with Britain and France, leading to an exchange of notes between the three governments in May 1907, by which time a strong cabinet led by Antonio Maura had come to power. The notes created an informal agreement to contain the German-led Central Powers; Britain would concentrate the bulk of the Royal Navy in the North Sea while Spain would contribute its fleet to support the French Navy against the combined fleets of Italy and Austria-Hungary. Britain and France would provide technical assistance to develop new warships for the Spanish fleet. Accordingly, Maura secured passage of the Fleet Plan of 1907, which proposed the construction of three battleships, several destroyers, torpedo boats, and other craft. The construction plan was to last for eight years. Debates over the plan took place in the ''Cortes Generales'' (General Courts—the Spanish legislature) until the end of November and a final approval vote on 2 December. The 1907 Fleet Plan was formally signed into law on 7 January 1908.

Development

Work on the new design had begun before the fleet plan was approved by the legislature. Initial plans called for the three ships to displace and have an armament of four and at least twelve guns in a manner similar to standard British pre-dreadnoughts of the period. The commissioning of the revolutionary "all-big-gun" in late 1906 prompted Commodore José Ferrándiz y Niño, the Spanish naval minister, to press the ''Junta Técnica de la Armada'' (Navy Technical Board) to revise its design to match the new, more powerful type of battleship in March 1907. Some consideration was given to reducing the caliber of the main battery to 11- or 9.2-inch (279 or 234 mm) guns, but six of the nine board members agreed that the 12-inch gun should be retained. With the general type of ship determined, the Navy began discussions over general design requirements, given the limitations that would be imposed on the new ships.

The Spanish Navy was principally concerned with defending its main naval bases at Ferrol, Cádiz, and Cartagena; given this requirement, the ships would not need an extensive cruising range. The need to keep the new battleship design tightly constrained due to the frail Spanish economy and industrial sector was of secondary importance. A third constraint was the need to build ships small enough to fit in existing dockyard facilities because Spain had insufficient funds to both build larger battleships and to enlarge the navy's dockyards. As a result, the design requirements called for relatively heavy offensive power with minimal range and armor protection. The Navy began discussing the design requirements with Armstrong Whitworth and Vickers in 1907. On 5 September 1907, Vickers provided a proposed design for a 15,000-ton battleship armed with eight 12-inch guns. This design was the basis for the requirements for the design competition, which was issued on 21 April 1908. Rather than simply order the ships from foreign builders, the government required any tender to include provisions for the submitter to take control of and modernize the Spanish shipyard facilities that would build the vessels. While this would increase costs and delay completion of the ships, the government decided improving domestic facilities was an important goal of the program.

Four shipbuilders submitted bids: the Italian Gio. Ansaldo & C. led a group that included the Austro-Hungarian Škoda Works and the French '' Marrel Freres Forges de La Loire et du Midi''; the French firm Schneider-Creusot partnered with '' Société Nouvelle des Forges et Chantiers de la Méditerranée'' and ''Forges et Chantiers de la Gironde''; the Spanish firm '' Sociedad Española de Construcción Naval'' (SECN), which was formed by Vickers, Armstrong Whitworth, and John Brown & Company; and a group of Spanish industrialists backed by Palmers Shipbuilding and Iron Company and William Beardmore and Company. Only the first three proposals were seriously considered; the fourth was considered to be too vague. The ''Junta Superior de la Armada'' (the Navy Staff) and the Navy Minister were responsible for reviewing the three proposals. Ansaldo prepared two design variants; the first called for four twin gun turrets for the main battery with one forward, one aft, and two offset amidships. The second proposal had two triple turrets fore and aft with a twin turret on the centerline amidships. Artillery experts in the Navy rejected the second variant. The SECN and Schneider designs featured the same arrangement as the first Ansaldo proposal.

In October 1908, the Artillery Committee met to make its recommendations to the ''Junta Superior''. The Committee concluded the SECN and Schneider proposals were superior to the Ansaldo version but neither had a marked advantage over the other. The following month, the Naval Construction Committee met to evaluate the proposals. It recommended the SECN design followed by Schneider and with Ansaldo last. The Office of the Navy Controller also evaluated the proposals in November and advised the ''Junta Superior'' only the SECN bid met the design requirements without any legal, administrative, or cost problems. Given the strategic context that foresaw the likely use of the ships against the Italian and Austro-Hungarian fleets, the Ansaldo-led consortium had obvious drawbacks. In February 1909, the Navy requested a revised design from SECN to incorporate several alterations including an increased freeboard to improve seakeeping, an increased height and length of the main belt armor, and the addition of individual rangefinders for each gun turret. SECN agreed to make the changes on 20 March and the company received the contract on 14 April.

Due to the constraints imposed by the Spanish economy, the resulting design produced the smallest dreadnought-type battleships ever built. They were obsolete before completion due to rapid technological change—most significantly the advent of the superdreadnought battleships—and lengthy delays in completion of the later units of the class.

Design

General characteristics

The ''España''-class ships were long at the waterline and long overall. They had a beam of and a draft of ; their freeboard was amidships, much lower than was normal for battleships of the period. They displaced as designed and up to at combat load. The vessels had two tripod masts and a small superstructure. They were equipped with six searchlights. The ships were reasonably stable compared to foreign designs but they had a low metacentric height of at full loading that caused them to have poor stability when damaged. Steering was controlled with a single semi-balanced rudder. At full speed, the ships could make a 180 degree turn in the space of .

Each ship had a crew of 854 officers and enlisted men, though in peacetime the crew was limited to around 700 for habitability reasons. The enlisted crew spaces were located forward in the upper deck and were cramped and unhygienic; they were split between two areas, the first being a large mess deck between the barbettes for the forward turret and the starboard wing turret. The rest of the enlisted men were housed in the forward casemates for the secondary guns. The cabins for non-commissioned officers were also located in the casemates. The superstructure included several cabins for senior officers. The ships were initially painted black but in the 1920s they were repainted gray. ''Alfonso XIII'' funnel bore a white identification band and ''Jaime I'' bore two; these bands were removed from both ships after the start of the Civil War. ''Jaime I'' was also repainted dark gray at this time.

Machinery

The ships' propulsion system consisted of four-shaft Parsons steam turbines and steam was provided by twelve coal-fired water-tube Yarrow boilers. The turbines drove three-bladed screw propellers that had diameters of . Two spare screws were kept aboard each ship. The boilers were trunked into a single funnel that was placed amidships; the funnel's location far from the foremast kept the latter's spotting top free from smoke interference but still rendered the spotting top on the mainmast essentially useless.

The engines were rated at and produced a top speed of . According to the design contract, the engines were to be capable of a normal maximum of with a top speed of , and up to and at forced draft. All three ships exceeded in speed trials. Each ship could store up to of coal; according to ''Conway's All the World's Fighting Ships'', this permitted a cruising radius of at a speed of , though the historian Agustín Rodríguez González states the ships had a range of at a speed of .

Armament

The ship's main armament consisted of eight Vickers Mk H. 12-inch 50-caliber guns. These guns were housed in four twin-gun turrets, arranged with two on the centerline fore and aft, the others ''en echelon'' as wing turrets. Each weighed and fired an 850-pound (385 kg) shell at a muzzle velocity of 3,000 ft/s (914 m/s). The guns had a maximum range of 23,500 yards (21,500 m) and a rate of fire of one round per minute. The turrets were hydraulically operated and could be loaded at any angle of elevation. The ''en echelon'' arrangement was chosen over superfiring turrets such as those used in the American dreadnoughts to save weight and cost. All four turrets could in theory fire on the broadside and three of them could fire ahead or astern. Blast effects from the wing turrets, however, generally prohibited firing them across the deck or directly ahead and astern.

The secondary battery comprised twenty , 50-caliber guns mounted individually in casemates along the length of the hull. They were manufactured by several Spanish arsenals and fired a shell. The guns were too close to the waterline, however; they were unusable in heavy seas and had a limited range caused by insufficient elevation. The guns were also too weak to be effective against contemporary destroyers, which were becoming increasingly powerful. The ships also carried four 3-pounder guns, two machine guns, and two landing guns that could be taken ashore.

Armor

The armor layout for the ''España'' class was essentially a scaled-down version of that used in the British . The reductions were mostly due to the heavy armament in a vessel of such limited displacement. The main belt armor was thick and tapered to on either end of the central citadel. The upper belt that protected the casemate guns was thick. Each turret, which had 8 in sides, sat on a barbette that was protected with thick plating. The conning tower also had 10-inch thick sides. Both the armored deck and the torpedo bulkhead were thick. The ships' heavy armor plating consisted of Krupp cemented steel, with Krupp homogeneous steel used for armor thinner than ; both types were manufactured in Britain.

Though the ships were poorly armored compared to most foreign designs, the ships' underwater protection was the greatest weakness in the armor scheme. The torpedo bulkhead was placed too close to the outer hull, which reduced its ability to absorb damage. This weakness played a central role in the losses of both ''España'' to grounding in 1923 and the sinking of ''Alfonso XIII'' by a single mine in 1937.

Modifications

Only limited modifications were possible due to technical constraints imposed by the need to keep displacement low and insufficient funds to effect a major reconstruction to free up tonnage for other uses. The arrangement of the main battery occupied much of the deck space, limiting what could be done to update the vessels. The Navy considered proposals to modernize the three battleships in the early 1920s but the Spanish military budget was being consumed by the costs of the Rif War in North Africa so the proposed modernization was not carried out. These modernization plans called for the installation of new fire control equipment with more effective rangefinders, additional, newer anti-aircraft guns, and the building of anti-torpedo bulges into the hull to improve underwater protection for a loss of one knot of speed. Deck armor was also to be strengthened. Only minor modifications were possible. In 1926, both ''Jaime I'' and ''Alfonso XII'' had a pair of Vickers anti-aircraft guns installed, one each on top of turret numbers 1 and 2. In the 1930s, the foremast was reduced slightly on the two surviving ships.

A more ambitious plan to significantly improve the surviving ships' capabilities was proposed in the mid-1930s. The height of the wing turret barbettes was to be increased, improving their fields of fire and freeing up space around the turrets for a new secondary battery of Mk F dual-purpose guns. The ships were to carry twelve of the guns individually in open mounts; the casemates of the old secondary guns would be converted into more crew spaces. A new anti-aircraft battery of either ten or eight guns were to be fitted, the type would be determined by tests of their effectiveness. Other changes were to be made to improve fire-control systems, overhaul the machinery, and install anti-torpedo bulges, among other improvements but the start of the Spanish Civil War in July 1936 prevented work on either ship from beginning.

After the Nationalists seized her in 1936, ''Alfonso XIII''—since renamed ''España''—had her guns removed for use ashore. They were replaced with four German SK C/30 flak guns and two C/30 anti-aircraft guns. ''Jaime I'', which remained with the Republicans, was reequipped with two Vickers 50-caliber anti-aircraft guns and a twin Hotchkiss mounting.

Construction

A new drydock and two slipways were built at Ferrol to accommodate the construction of the three battleships. All material except the armor plate, heavy guns, and fire control equipment was manufactured in Spain. The contract specified a build time of four years for the first ship, five years for the second, and seven years for the third. Despite the allowance for longer construction times for the later units, their completion, particularly that of the third unit, ''Jaime I'', was delayed by a lack of materials from Britain as a result of the outbreak of World War I in July 1914. The main guns for ''Jaime I'' were not delivered until 1919; she had been completed apart from her armament in May 1915.

History

Early careers

''España'' was the only member of the class that was completed by the outbreak of World War I in August 1914, though she did not see action because Spain remained neutral for the duration of the war. In August 1914, she participated in the opening ceremonies for the Panama Canal. ''Alfonso XIII'' joined her in August 1915 in the 1st Squadron of the Spanish fleet. During the war, the fleet conducted training operations in home waters. ''Alfonso XIII'' was involved in assisting ships in distress and suppressing civil unrest during and immediately after the war. In late 1921, ''Jaime I'' was completed. Throughout the early 1920s, the three ships served in the Training Squadron. ''España'' and ''Alfonso XIII'' were sent on long-distance cruises to North and South America in 1920 and 1921, respectively. During ''España''s voyage, she was damaged off the coast of Chile and required extensive repairs before she could return home.

During this period, the Riffians living in Spanish Morocco rebelled against the Spanish colonial government, initiating the Rif War in mid-1921. All three ''España''-class battleship saw action during the conflict, primarily providing artillery support to Spanish ground forces engaging the Rif rebels. In August 1923, while bombarding Rif positions, ''España'' ran aground off Cape Tres Forcas. A lengthy salvage operation failed to free the ship, and, in November 1924, severe storms battered the wreck and broke the hull in half, rendering her a complete loss. ''Alfonso XIII'' served as the flagship of the Spanish fleet during the landing at Alhucemas in 1925. Spanish forces were able to defeat the rebels by 1927.

In 1931, after the overthrow of King Alfonso XIII and the establishment of the Second Spanish Republic, his namesake battleship was renamed ''España'' to erase traces of the monarchy. Both vessels were immediately decommissioned to reduce costs during the Great Depression, though ''Jaime I'' was recommissioned in 1933 to serve as the fleet flagship. In the mid-1930s, the Spanish Navy considered modernization programs for the two surviving battleships but none came to fruition, mainly because of the outbreak of the Spanish Civil War in July 1936. ''España'' was undergoing a limited refit to bring her back into service in anticipation of the modernization when the Spanish coup of July 1936 initiated the conflict.

Spanish Civil War

In 1936 at the start of the Nationalist uprising led by General Francisco Franco, the bulk of the Spanish Navy's fleet remained loyal to the Republican government. When most of the ship's officers declared support for Franco, ''España''s crew killed most of them, but, after a duel with Nationalist coastal artillery batteries, they were persuaded to surrender and turn the ship over to Nationalist control. ''Jaime I'' remained under Republican control, serving as the core of the Spanish Republican Navy. The Republican fleet attempted to block the crossing of Franco's Army of Africa from Morocco to mainland Spain, resulting in a brief action between ''Jaime I'' and the gunboat , but German interference secured the Nationalists' passage. In August of that year, ''Jaime I'' was attacked and slightly damaged by two German bombers from the Condor Legion.

After being returned to service, ''España'' was used for coastal bombardment and to enforce the blockade of Republican ports in northern Spain, including Gijón, Santander, and Bilbao, frequently seizing vessels carrying supplies to the Republicans. ''Jaime I'' shelled Nationalist positions in Spanish Morocco and in September 1936 sortied with a pair of cruisers and four destroyers to disrupt the blockade imposed by ''España''. Neither ship engaged the other and the Republicans withdrew in October that year, having achieved nothing. After returning to Spain's Mediterranean coast, ''Jaime I'' ran aground, necessitating repairs at Cartagena. While there in May 1937, she was attacked by five Savoia-Marchetti SM.79 bombers of the Italian ''Aviazione Legionaria''. Reports of the damage inflicted are mixed; according to Albert Nofi the ship sustained minor damage but Marco Mattioli wrote the damage was more serious.

''España'' was lost on 30 April 1937 off the coast of Santander while on blockade duty, having struck a single mine that had been laid by a Nationalist minelayer. She remained afloat long enough for the destroyer to take off most of her crew and only four men died in the sinking. ''Jaime I'' was still under repair at Cartagena in June when an accidental fire caused an internal explosion that destroyed the ship. The Republicans raised the ship but determined she was beyond economical repair and discarded her on 3 July 1939.

Many of the guns from the first ''España'' were recovered and used in coastal fortifications, some of which remained in service until 1999. Six of ''Jaime I''s 12-inch guns were also salvaged and similarly employed after she was broken up in the 1940s. ''Jaime I'' guns also remained in service until they were decommissioned in the mid-1990s. The second ''España'' (formerly ''Alfonso XIII'') was never raised and her wreck was discovered in the early 1980s. Several expeditions to survey the wreck took place between February and May 1984.
