Salamis () was a partially constructed capital ship, referred to as either a dreadnought battleship or battlecruiser, that was ordered for the Greek Navy from the AG Vulcan shipyard in Hamburg, Germany, in 1912. She was ordered as part of a Greek naval rearmament program meant to modernize the fleet, in response to Ottoman naval expansion after the Greco-Turkish War of 1897. Salamis and several other battleships—none of which were delivered to either navy—represented the culmination of a naval arms race between the two countries that had significant effects on the First Balkan War and World War I.

The design for Salamis was revised several times during the construction process, in part due to Ottoman acquisitions. Early drafts of the vessel called for a displacement of , with an armament of six guns in three twin-gun turrets. The final version of the design was significantly larger, at , with an armament of eight 14-inch guns in four turrets. The ship was to have had a top speed of , higher than that of other battleships of the period.

Work began on the keel on 23 July 1913, and the hull was launched on 11 November 1914. Construction stopped in December 1914, following the outbreak of World War I in July. The German navy employed the unfinished ship as a floating barracks in Kiel. The armament for this ship was ordered from Bethlehem Steel in the United States and could not be delivered due to the British blockade of Germany. Bethlehem sold the guns to Britain instead and they were used to arm the four s. The hull of the ship remained intact after the war and became the subject of a protracted legal dispute. Salamis was finally awarded to the builders and the hull was scrapped in 1932.

Development

Following the Greco-Turkish War of 1897, during which the Ottoman fleet had proved incapable of challenging Greece's navy for control of the Aegean Sea, the Ottomans began a naval expansion program, initially rebuilding several old ironclad warships into more modern vessels. In response, the Greek government decided in 1905 to rebuild its fleet, which at that time was centered on the three s of 1880s vintage. Beginning in 1908, the Greek Navy sought design proposals from foreign shipyards. Tenders from Vickers, of Britain, for small, battleships were not taken up.

In 1911, a constitutional change in Greece allowed the government to hire naval experts from other countries, which led to the invitation of a British naval mission to advise the navy on its rearmament program. The British officers recommended a program of two battleships and a large armored cruiser; offers from Vickers and Armstrong-Whitworth were submitted for the proposed battleships. The Vickers design was for a smaller ship armed with nine guns, while Armstrong-Whitworth proposed a larger ship armed with guns. The Greek government did not pursue these proposals. Later in the year, Vickers issued several proposals for smaller vessels like those it had designed in 1908.

The initial step in the Greek rearmament program was completed with the purchase of the Italian-built armored cruiser in October 1909. The Ottomans, in turn, purchased two German pre-dreadnought battleships, and , amplifying the naval arms race between the two countries. The Greek Navy attempted to buy two older French battleships, and when that purchase failed to materialize, they tried unsuccessfully to buy a pair of British battleships. They then tried to buy ships from the United States, but were rebuffed due to concerns that such a sale would alienate the Ottomans, with whom the Americans had significant industrial and commercial interests. The Ottomans ordered the dreadnought in August 1911, threatening Greek control of the Aegean. The Greeks were faced with a choice of conceding the arms race, or ordering new capital ships of their own.

Rear Admiral Lionel Grant Tufnell, the head of a British naval mission to Greece, advocated purchasing another armored cruiser like Georgios Averof, along with several smaller vessels, and allocating funds to modernizing the Greek naval base at Salamis; this proposal was supported by Prime Minister Eleftherios Venizelos, who sought to control naval spending in the tight Greek budget projected for 1912. The plan came to nothing, as the Greek government waited for the arrival of British advisers for the Salamis project. In early 1912, the Greek Navy convened a committee that would be in charge of acquiring a new capital ship to counter Reşadiye, initially conceived as a battlecruiser. The new ship would be limited to a displacement of , since that was the largest vessel the floating dry dock in Piraeus could accommodate. The program was finalized in March, and along with the new battlecruiser, the Greeks invited tenders for destroyers, torpedo boats, submarines, and a depot ship to support them.

Ten British, four French, three German, three American, one Austrian, and two Italian shipyards all submitted proposals for these contracts, with Britain's Vickers and Armstrong-Whitworth submitting the same designs proposed in 1911. Tufnell was part of the committee overseeing the process, but found that the Greeks strongly opposed the British designs. Vickers eventually withdrew from the competition, and the cost of Armstrong's proposal was higher than other proposals. Still, the British had hopes of obtaining the contract due to the relationship between the Greek and British navies, reflected by the number of British officers that had been seconded to the Greek Navy in recent years. French yards, on the other hand, complained that the British were unfairly benefiting from the presence of their naval mission. During the competition, the Greek Navy decided that Vickers' hull design was best, but American guns, ammunition, and armor were superior to any of the British designs. In the end, neither got the contracts, as negotiations between Venizelos and the German Minister to Greece eventually secured the contracts for Germany.

In June 1912, the Greek Navy selected tenders from Germany's AG Vulcan for two destroyers and six torpedo boats, to be completed in just three to four months. This exceptionally short timeframe was accomplished through the help of the German Navy, which allowed the Greeks to take over German ships then being constructed. The contract price was evidently low, as one British firm complained that they could not understand how Vulcan would make a profit. Then, one month later, the Greeks selected Vulcan again for the construction of their battlecruiser, with its armor and armament coming from Bethlehem Steel in the United States. British firms were furious, again alleging that it would be impossible for Vulcan to make a profit on the contract, and surmising that the German government was subsidizing the purchase to get a foothold in the shipbuilding market. The Greeks, for their part, countered that the British manufacturers were colluding to keep armor plate prices high, and so they were able to significantly decrease their costs by ordering the ship's armor in the United States.

Design

The initial design called for a ship long with a beam of , a draft of , and a displacement of . The ship was designed with 2-shaft turbines rated at 26,000 shp for a top speed of . The armament was to be six guns in twin turrets all on the centerline with one amidships, eight , eight , and four guns, and two torpedo tubes.

The design was revised several times. In mid-1912, as tensions were developing that led to the First Balkan War, the Greek Navy began serious efforts to increase its strength. In August, they were seeking only minor alterations in the ship design, but early naval operations during the war convinced the naval command of the advantages a larger ship would provide. Tufnell suggested a different reason for the design changes, accusing the Germans of offering a cheap but unseaworthy design, obtaining the contract, then making a push for a more expensive but also more practical design.

Hovering over all of these was the possibility that the dreadnoughts of the South American dreadnought race could be put up for sale, a prospect both countries pursued. Two, from Brazil, were already completed, and a third was under construction in Britain. Another two, for Argentina, were being built in the United States. Naval historian Paul G. Halpern wrote of this situation that "the sudden acquisition by a single power of all or even some of these ships might have been enough to tip a delicate balance of power such as that which prevailed in the Mediterranean." Both the Greeks and Ottomans were reportedly interested in the Argentine ships, and Venizelos attempted to buy one of the s then being built in the United States for the Argentine Navy as an alternative to redesigning Salamis, in the process delaying her completion.

When the Argentine government refused to sell the ship, he agreed to redesigning Salamis, and a committee that included Greek and British naval officers was created to revise the design. The committee favored a design, but Hubert Searle Cardale, the only member of the British mission drawn from the Royal Navy's active list, proposed an increase to , since the increase would allow for a substantially more powerful vessel. Venizelos initially approved an increase in displacement to 16,500 LT, but he opposed any further increases. The Foreign Minister, Lambros Koromilas, and the Speaker of the Parliament, Nikolaos Stratos, conspired to have the larger proposal adopted while Venizelos was attending the peace conference that resulted in the Treaty of London. Koromilas and Stratos misrepresented Venizelos' position to the rest of the cabinet and secured their approval for the new contract.

Koromilas' and Stratos' deception proved effective, and the enlarged proposal was adopted on 23 December 1912. The most significant changes were a 50% increase in displacement, the addition of a fourth twin-gun turret, and the arrangement of the main battery in superfiring pairs. The ship was to be delivered to the Greek Navy by March 1915, at a cost of £1,693,000. M. K. Barnett, writing for Scientific American, remarked that the ship would "not mark any particular advance in warship design, being, rather, an effort to combine the greatest defensive and offensive qualities with the least cost." The Journal of the American Society of Naval Engineers, however, believed that the ship was designed for speed and firepower at the expensive of heavy defensive armor. Upon his return, Venizelos attempted to have the new contract cancelled, but Vulcan refused, noting that "Prime Ministers rise and fall from power and the influence of Venizelos will not be enduring." The order for Salamis, which has been referred to alternatively as a battleship or battlecruiser, made Greece the fourteenth and final country to order a dreadnought-type ship.

The modifications to the design came over the objections of the British, including Prince Louis of Battenberg and the new head of the British naval mission in Greece, Rear Admiral Mark Kerr. Battenberg wrote that a Greek purchase of modern capital ships would be "undesirable from every point of view", as the country's finances could not support them and the increasing power of torpedoes were making smaller ships more dangerous. Along much the same lines, Kerr suggested to Venizelos that a fleet built around smaller warships would be better suited for the constricted Aegean Sea. Strongly opposing these views were the Greek Navy and King Constantine I of Greece, both of whom desired a regular battle fleet, as they believed that it was the only way of assuring Greek naval superiority over the Ottomans.
