Design and description

The Charles Martel group of battleships all shared the same layout for their main and secondary armament—a design that minimised the cramped upper decks produced by the pronounced tumblehome
Tumblehome
In ship designing, the tumblehome is the narrowing of a ship's hull with greater distance above the water-line. Expressed more technically, it is present when the beam at the uppermost deck is less than the maximum beam of the vessel....

 favoured by French designers, and capitalised on the bulging sides of the vessels. The bow and stern turrets had only a single gun and were placed uncomfortably close to the extremities of the ship in Jauréguiberry because she was some 7 metres (23 ft) shorter than the other ships in the group. The single turrets of the secondary armament were mounted on the ship's beam, while the 138 millimetres (5.4 in) guns were mounted in four twin turrets sited symmetrically behind and outboard of the main gun turrets.

General characteristics

Jauréguiberry was 111.9 metre long overall. She had a maximum beam
Beam (nautical)

 of 8.45 metre. She displaced 11818 tonnes (11,631 LT) at normal load and 12229 tonnes (12,035.8 LT) at full load. In 1905 her captain described her as an excellent sea-boat and a good fighting ship, although her secondary armament was too light. He also said that she was stable and well laid-out with good living conditions.

Propulsion

Jauréguiberry had two vertical triple expansion steam engines, also built by Forges et Chantiers de la Méditerranée. On trials they developed 14441 ihp and drove the ship to a maximum speed of 17.71 knots (9.6 m/s). Each engine drove a 5.7 metre propeller. Twenty-four Lagraffel d'Allest water-tube boiler

s provided steam for the engines at a pressure of 15 kg/cm2. She normally carried 750 tonnes (738 LT) of coal, but could carry a maximum of 1080 tonnes (1,063 LT). This gave her a radius of action of 3920 nautical mile at 10 knots (5.4 m/s).

Armament

Jauréguiberrys main armament consisted of two 305 millimetres (12 in) 45-calibre

ed out over the tumblehome of the ship's sides. Eight 45-calibre 138 mm Canon de 138.6 mm Modèle 1891 guns were mounted in manually operated twin turrets at the corners of the superstructure with 160° arcs of fire. The guns could depress to -10° and elevate to +25°. They fired 36.5 kilograms (80.5 lb) armour-piercing

An armor-piercing shell is a type of ammunition designed to penetrate armor. From the 1860s to 1950s, a major application of armor-piercing projectiles was to defeat the thick armor carried on many warships. From the 1920s onwards, armor-piercing weapons were required for anti-tank missions...

 shells at a muzzle velocity of 725 metres per second (2,378.6 ft/s) which gave a range of 15000 m (16,404.2 yd) at maximum elevation. Their rate of fire was about 4 rounds per minute.

s was provided by a variety of light-caliber weapons. Sources disagree on the number and types, possibly indicating changes over the ship's lifetime. All sources agree on four 50-calibre 65 millimetres (2.6 in) (9-pounder) guns. These fired a 4.1 kilograms (9 lb) shell at a muzzle velocity of 715 metres per second (2,345.8 ft/s).

She returned to the Mediterranean Fleet in February 1907 where she was assigned to the Reserve Division, and the following year was reassigned to the Third Division. In 1909 the 3rd and 4th Divisions were reformed into the 2nd Independent Squadron and transferred to the Atlantic in 1910. Beginning on 29 September 1910 her boiler tubes were renewed at Cherbourg. In October 1912 the Squadron was reassigned to the Mediterranean Fleet and a year later, in October 1913, Jauréguiberry was transferred to the Training Division of which she became the flagship

She arrived at Toulon on 6 March 1919 where she was decommissioned and transferred to the Engineer's Training School on 30 March for use as an accommodation hulk. She was stricken from the Navy List on 20 June 1920, but remained assigned to the Engineer's School until 1932. Jauréguiberry was sold for scrapping on 23 June 1934 for the price of 1,147,000 F.
