until January 1917. The secondary battery consisted of twenty-two Canon de 138 mm Modèle 1910 guns in casemates along the length of the hull. She also carried seven Hotchkiss guns, two on the conning tower and one on the roof of each turret. The ship was also armed with four submerged torpedo tubes. The ship's main belt was thick and the main armored deck was thick. The main battery was protected by up to of armor on the turrets and the casemates for the secondary guns were thick. The conning tower had thick sides. Service Lorraine was ordered on 15 July 1912, as a replacement for the battleship Liberté, which had been destroyed by a magazine explosion the previous year. She was laid down at the Chantiers de Penhoët shipyard in Saint-Nazaire on 1 August 1912 and launched on 30 September 1913. She was commissioned into the French Navy on 10 March 1916. After entering service in 1916, Lorraine and her sisters were assigned to the 1st Division of the 1st Battle Squadron. The three ships remained in the unit for the remainder of the war. They spent the majority of their time at Corfu to prevent the Austro-Hungarian fleet from attempting to break out of the Adriatic. The fleet's presence was also intended to intimidate Greece, which had become increasingly hostile to the Triple Entente. Later in the war, men were drawn from their crews for anti-submarine warfare vessels. As the Austro-Hungarians largely remained in port for the duration of the war, Lorraine saw no action during the conflict.

In January 1919, she went to Cattaro, where she guarded the former Austro-Hungarian Navy. She assisted in repatriating Austrian naval personnel, and escorted former Austro-Hungarian warships to France and Italy; this duty lasted until March.

The two ships went to Constantinople in October 1919, where they formed the core of the Eastern Mediterranean Squadron, which operated until July 1921.
