The class consisted of four pre-dreadnought battleships built for the French Navy in the early 1900s. The class comprised , , , and . They were ordered as part of a naval expansion program directed at countering German warship construction authorized by the German Naval Law of 1898; the French program called for six new battleships, which began with the two s. During construction of the first two vessels, foreign adoption of heavier secondary batteries prompted the French to re-design the last four members to carry a secondary battery of guns, producing the class. Like the s, their main armament consisted of four guns in two twin-gun turrets, and they had the same top speed of .
Their peacetime careers were largely uneventful, consisting of a normal routine of training exercises, visits to various French and foreign ports, and naval reviews for French politicians and foreign dignitaries. In 1909, , , and visited the United States during the Hudson–Fulton Celebration. was destroyed by an accidental explosion of unstable propellant charges in Toulon in 1911, prompting the fleet to enact strict handling controls to prevent further accidents. The three surviving ships were deployed to guard troop convoys from North Africa to France in the early days of World War I, thereafter deploying to the Adriatic Sea in an attempt to bring the Austro-Hungarian Navy to battle. The fleet sank an Austro-Hungarian cruiser in the Battle of Antivari but was otherwise unsuccessful in its attempt to engage the Austro-Hungarians. was briefly deployed to the Dardanelles in September 1914, where she bombarded Ottoman coastal defenses.
In 1916, the ships were sent to Greece to put pressure on the still-neutral government to join the war on the side of the Allies. The French ultimately intervened in a coup that overthrew the Greek king and brought the country into the war. The ships thereafter spent much of the rest of the war at Corfu, where they saw little activity owing to coal shortages. Following the Allied victory, and were sent to the Black Sea to oversee the demilitarization of Russian warships German forces had seized during the war, and went to Constantinople to oversee the Ottoman surrender. All three ships were recalled in mid-1919, and was decommissioned immediately thereafter. The other two ships were deactivated in 1920. All three were sold for scrap in 1921 and broken up in Italy or Germany. , still on the bottom of Toulon's harbor, was raised in 1925 and scrapped there.
Design
The class, sometimes considered part of the preceding , was authorized in the Fleet Law of 1900, which called for a total of six battleships, the first two of which were the class. The law was a reaction to the German 1898 Naval Law, which marked a significant expansion of the fleet under Admiral Alfred von Tirpitz. Since Germany was France's primary potential opponent, a considerable strengthening of its fleet pressured the French parliament to authorize a similar program. Louis-Émile Bertin, who had become the (DCCN—Central Director of Naval Construction) in 1896, was responsible for preparing the new design. Bertin had campaigned through the early 1890s for revisions to the battleships then being built, as he correctly determined that their shallow belt armor would render them vulnerable to hits above the belt that could cause flooding that would dangerously destabilize the vessels.
Upon becoming the DCCN, Bertin was now in a position to advance his ideas on battleship construction. In November 1897, he called for a battleship displacing , a significant increase in size over earlier battleships, which would allow him to incorporate the more comprehensive armor layout he deemed necessary to defeat the latest generation of armor-piercing shells. The new ship would be protected by a tall belt that covered much of the length of the hull, topped with a flat armored deck that created a large armored box, which was highly subdivided with watertight compartments to reduce the risk of uncontrollable flooding.
Detailed design work on the new ship continued for the next two years, as the design staff worked out the particulars of the ship. The staff submitted a revised proposal on 20 April 1898, with displacement now increased to , which was on par with contemporary British designs. To ensure passage through the Suez Canal, draft was limited to and the standard main armament of four guns in two twin-gun turrets was specified. The naval command approved the submission, but requested alterations to the design, particularly to the arrangement of the secondary battery layout. These proved difficult to incorporate, as the requested changes increased topweight, which necessitated reductions in armor thicknesses to keep the ship from becoming too top-heavy. The navy refused to allow the reductions, however, and so further rearrangements were considered.
On 23 December, the designers evaluated a pair of proposals for the secondary gun turrets from Schneider-Creusot and the government-run (Artillery Directorate); the proposal from the latter was adopted for the new ship. Another meeting on 28 April 1899 settled on the final characteristics of the design, and on 29 May, Bertin was directed to alter the design to conform to the adopted specifications. Final design work took another two months, and Bertin submitted the finalized version on 8 August. After nearly a year of inaction, Jean Marie Antoine de Lanessan, the Minister of the Navy, approved the design on 10 July 1900, and on 9 December the parliament approved the 1900 Fleet Law that authorized a total of six ships.
During the lengthy design process, new battleships being built abroad, particularly the British s, led to a re-design of the last four members of the class, resulting in the s. Foreign battleships began to carry a heavy secondary battery, such as the guns of the King Edward VIIs, which prompted an increase in French secondary batteries from for the last four ships. Unfortunately for the French ships, they entered service shortly after the revolutionary all-big-gun battleship was completed for the Royal Navy, rendering pre-dreadnoughts like them obsolescent. The s nevertheless provided the basis for the subsequent French battleships of the .
General characteristics
The ships were long at the waterline, long between perpendiculars, and long overall. They had a beam of at the waterline and an average draft of . They displaced up to at full load. The ships' hulls were modeled on the s, which Bertin had also designed. The hulls were divided into 15 watertight compartments below the lower armor deck. Bilge keels were fitted to improve their stability.
The -class ships were built with a tall forecastle deck that extended all the way to the mainmast. They retained a small fighting mast for the foremast, but had a lighter pole mast for the mainmast. The forward superstructure consisted of a four-deck structure erected around the foremast and the conning tower. The charthouse, commander's quarters, and bridge were located here. In service, the arrangement proved to have several problems; the conning tower was too small to accommodate the crew, the bridge wings obstructed views aft, which forced the commander to leave the safety of the armored conning tower to see all around the ship. In 1912–1913, the wings were removed to reduce the problem. Similar problems caused difficulties in the aft superstructure as well, particularly with the rear fire control system.
They had a crew of 32 officers and 710 enlisted men, though while serving as a flagship, their crews were increased to 44 officers and 765 enlisted men to include an admiral's staff. Each battleship carried eighteen smaller boats, including pinnaces, cutters, dinghies, whalers, and punts. As a flagship, these boats were augmented with an admiral's gig, another cutter, and three more whalers. As completed, the ships wore the standard paint scheme of the French fleet: green for the hull below the waterline and black above, and buff for the superstructure. This scheme was replaced in 1908 with a medium blue-gray that replaced the black and buff, while the green hull paint was eventually replaced with dark red.
Machinery The ships were powered by three 4-cylinder vertical triple expansion engines with twenty-two Belleville boilers, with the exception of , which received twenty-four Niclausse boilers. The boilers were divided into four boiler rooms, with the forward three trunked into two funnels and the aft room ducted into the rear funnel. The engines were located amidships in separate watertight compartments, between the forward group of three boiler rooms and the aft one. Each engine drove a bronze, three-bladed screw; the centerline propeller was in diameter and the outboard screws were in diameter. The ships were equipped with six electric generators; two 500-ampere generators were used to power the main battery turrets and ammunition hoists and four 800-amp generators provided power for the rest of the ships' systems.
The propulsion system was rated at and provided a top speed of as designed. Coal storage amounted to normally and up to at full load. At an economical cruising speed of , the ships could steam for .
Armament
The main battery for the -class ships consisted of four Canon de 305 mm Modèle 1893/96 guns mounted in two twin-gun turrets, one forward and one aft. These guns fired a shell at a muzzle velocity of . At their maximum elevation of 12 degrees, the guns had a range of . Their rate of fire was one round per minute. Both the turrets and the guns were electrically operated; both guns were typically elevated together, but they could be decoupled and operated independently if the need arose. The guns had to be depressed to a fixed loading position, −5 degrees, between shots. Ready ammunition storage amounted to eight rounds per turret. Though earlier French battleships had carried several types of shells, including armor-piercing (APC), semi-armor-piercing (SAPC), cast iron, high-explosive, and shrapnel shells, the s standardized on a load-out of just APC and SAPC shells. In peacetime, each gun was supplied with 65 shells, for a total of 260 per ship, of which 104 were APC and the remaining 156 were SAPC. The wartime supply was three times that, at 780 shells in total.
The secondary battery consisted of ten Modèle 1902 guns; six were mounted in single turrets and the remaining four were in casemates in the hull. The six turrets were distributed along the central portion of the ship, two abreast the forward pair of funnels, two amidships, and the last pair abreast the rear funnel. The casemate guns were arranged in pairs, one on either side of the forward main battery turret, and the other was slightly forward of the rear pair of secondary turrets. The guns had a firing rate of two shots per minute. With a maximum elevation of 15 degrees, the guns had a range of . Muzzle velocity was . The turrets were electrically trained but manually elevated, while the casemate guns were entirely manually operated. Both had a storage capacity of twelve rounds and their propellant charges, before ammunition had to be retrieved from the magazines. Each gun was supplied with 200 shells, of which 150 were SAPC and the remainder were APC. The ships also carried a total of 78 cast iron shells and 20 training rounds.
