Project history

Built under the 1912 programme, first and unique French superdreadnoughts. The basic changes from Courbet design were brought to introduction of new main guns, and protection even has been a little weakened, and armour thickness mismatched artillery calibre. Ships received longitudinal anti-torpedo bulkhead, but the small thickness (8mm) did its practically useless. By August, 1914 ships were in a high readiness degree, therefore they became unique large ships of the French Navy which nevertheless have been completed during the First World War.

Bretagne class ships were strongest dreadnoughts of French Navy, but by the time of commission they already yielded to many foreign colleagues. They had unsatisfactory seaworthiness, unreliable boilers and small elevation angle of 340mm guns (12°) and, accordingly, an insufficient firing range (14.5km). Last lack was corrected in 1917 only on Lorraine, having increased maximal elevation angle to 18° and a firing range to 18km. Remaining ships had similar modernization already after war.

Ship protection

Complete main belt had height 4.05m (2.35m above water), its thickness was 250mm at 99m length amidships (tapering to 220mm at upper and to 100mm at lower edges) and 160mm at ship ends (tapering respectively to 140 and 80mm). Upper 160mm belt covered the part between turret No1 and aft casemate. 60m long forecastle casemate had also 160mm protection. Main deck had 45mm thickness at flat part and connected with lower edge of main belt by 70mm slopes. Flat 40mm upper deck laid on the top of main belt. There was 40mm forecastle deck. Main turrets had 152mm sides and 72mm crowns, turrets No1 and No5 had 340mm faces, turrets No2 and 4 had 250mm and turret No3 400mm. Barbettes of turrets No1 and 5 had 248mm protection and No 2, 3 and 4 270mm. Longitudinal torpedo bulkhead had only 8mm thickness.

Naval service

In days of WWI Bretagne class battleships have not made any shot on the enemy. Provence in 1916-1919 served as a flag ship, participated in neutralisation of the Greek fleet (19.10.1916).

Lorraine 13/11-1.12.1939 carried to Canadian Halifax about 1500 boxes with a part of French gold. 11-22.3.1940 Bretagne has forwarded there 1220 more boxes (~61t)

Bretagne 3.7.1940 at Mers-el-Kebir was sunk by British Force "H" (battleship Resolution) in operation "Catapult", Provence was damaged by two hits and ran aground. The same year she was salvaged and translated to Toulon where in November, 1940 disarmed. She was scuttled together with the remaining ships of fleet, but raised by Italians 11.7.1943. Two main guns were used for restoration of battery "Cepet" near Toulon. In August, 1944 Provence was scuttled by Germans, raised again in 1949 and scrapped.

Lorraine in June, 1940 participated in operations on Mediterranean. In July as a part of Force "X" she was disarmed in Alexandria, but remained under the French control. She joined FNFL in December, 1942 and 30.5.1943 Lorraine has come over to the side of the Algerian Government. In 1944-1945 as a part of Allied squadron she served at the Mediterranean coast of France. Lorraine served as training gunnery hulk from June 1945, converted to accommodation ship in February 1947 and finally stricken in February 1953.
