French tanker Marne


Marne was a command and replenishment tanker of the French Navy. In addition to its primary duty as a fleet tanker, Marne was configured as a flagship and served as such in the Indian Ocean.

Development and design

In French service, the final three tankers are called Bâtiment de commandement et ravitailleur. In addition to their role as a fleet tanker, the three ships dubbed BCR can accommodate an entire general staff and thus supervise naval operations as a command ship. The three ships of the class designated BCRs,, Marne and all have superstructures that were extended aft by to accommodate the additional staff requirements. The BCRs have one crane positioned along the centreline.
Durance-class ships have a standard displacement of and at full load. The oiler is long overall and between perpendiculars with a beam of and a draught of empty and at full load. Marne is powered by two SEMT Pielstick 16 PC2.5 V 400 diesel engines turning two LIPS controllable pitch propellers rated at. The vessel has a maximum speed of and a range of at.
They have two dual solid/liquid underway transfer stations per side and can replenish two ships per side and one astern. The ship initially had capacity for of fuel oil, of diesel fuel, of JP-5 aviation fuel, of distilled water, of provisions, of munitions and of spare parts. These numbers change with the needs of the fleet.
The Durance-class tankers all mount a flight deck over the stern and a hangar. The ships utilise Aérospatiale Alouette III and Westland Lynx helicopters but are capable of operating larger ones from their flight deck. For defence, Marne initially mounted one Bofors /L60 anti-aircraft gun in a single gun turret and two AA guns in a twin turret. The ship was equipped with two DRBN 34 navigational radars. The armament was later altered by removing the 20 mm guns and adding four M2 Browning machine guns and three launchers for Simbad Mistral surface-to-air missiles. The ship had a complement of 162 and was capable of accommodating 250 personnel.

Construction and career

The fourth tanker of the Durance class was laid down on 4 August 1982 by Brest Arsenal at their yard in Brest, France. She was launched on 2 February 1985 and given the pennant number A 630. Marne was commissioned into the French Navy on 16 January 1987. The Durance-class ships were assigned to the Force d'action navale after entering service. One of the BCRs was assigned to Indian Ocean as flagship of the French naval forces in the region. In addition to its mission of logistical support for other ships, Marne like its sister ships Var and Somme could accommodate additional command staff of 45 people.
As of late 2021, only Marne and her sister ship Somme remained in service. The two ships were expected to be replaced by the new Jacques Chevallier-class vessels, with Marnes retirement anticipated in 2023. On 26 February 2023 Marne was said to have conducted her last at-sea replenishment of the aircraft carrier. Her colours were lowered for the final time in October 2023, formally taking her out of service.
