French destroyer Arc

Arc was a Arquebuse-class destroyer contre-torpilleur d'escadre built for the French Navy in the first decade of the 20th century. Completed in 1904, the ship was assigned to the Northern Squadron (Escadre du Nord).

Design and description
The Arquebuse class was designed as a faster version of the preceding Durandal-class destroyer. The ships had an overall length of 56.58 m, a beam of 6.3 m, and a maximum draft of 3.2 m. They normally displaced 307 t and 357 t at deep load. The two vertical triple-expansion steam engines each drove one propeller shaft using steam provided by two du Temple Guyot or Normand boilers. The engines were designed to produce a total of 6300 ihp for a designed speed of 28 kn, all the ships exceeded their contracted speed during their sea trials with Arc reaching a speed of 28.9 kn. They carried enough coal to give them a range of 2300 nmi at 10 kn. Their crew consisted of four officers and fifty-eight enlisted men.

The main armament of the Arquebuse-class ships consisted of a single 65 mm gun forward of the bridge and six 47 mm Hotchkiss guns in single mounts, three on each broadside. They were fitted with two single rotating mounts for 381 mm torpedo tubes on the centerline, one between the funnels and the other on the stern.

Construction and career
Arc (Bow) was ordered from Schneider et Cie on 29 May 1901 and the ship was laid down later that year at its shipyard in Chalons-sur-Saône. She was launched on 24 December 1902 and conducted her sea trials from July 1903 to July 1904. The ship was commissioned (armée definitif) after their completion and was assigned to the Mediterranean Squadron.

When the First World War began in August 1914, Arc was a leader (divisionnaire) in the 2nd Submarine and Destroyer Flotilla (2e escadrille sous-marins et torpilleurs) of the 1st Naval Army (1ère Armée navale), based at Bizerte, French Tunisia.
