The fourth unit, the BSAM Garonne, whose first assumption of command will take place in Concarneau in March, is set to be delivered in the summer of 2019. The four vessels are entirely built at the Piriou and Kership yards in Concarneau and Lorient.
The French Navy recently changed the designation of several vessels in its fleet. Previously known as BSAH (for Bâtiments de Soutien et d’Assistance Hauturiers or Offshore Support & Assistance Vessel) the Loire-class is known designated as BASM (for Bâtiments de Soutien et d’Assistance Métropolitains or Metropolitan Offshore Support & Assistance Vessel).
Loire-class vessels can conduct a wide range of support missions: They were designed to accommodate divers, to carry weapons and ammunition, to support submarines and surface ships, to tow underwater antennas, as well as to deploy a pollution control dam. They have a towing capacity of 80 tons of traction, a navigation speed of 14 knots and a significant endurance of about 30 days (without refueling). They are fitted with an 8 meters boat, several RHIBs and a crane for loading and unloading containers.
