DCNS begins upgrade work on final French ballistic nuclear submarine


DCNS has started regular overhaul (ROH) / adaptation work to integrate the M51 missile on the final of three French ballistic nuclear submarines (SSBN), Le Téméraire.

While preparation operations on the vessel were performed at Île Longue, ROH work on the submarine will be carried out at dock 8 of the naval base in Brest.

The company has been carrying out adaptation work on the submarines since 2010 to integrate the new M51 (IA M51) strategic missile.

"This complex project illustrates the expertise of DCNS, as prime contractor and project supervisor."

The missile was developed under the project management of the French Defence Procurement and Technology Agency (DGA).

IA M51 programme director Michel Drévillon said: “This complex project illustrates the expertise of DCNS, as prime contractor and project supervisor.

“In addition to our own teams on the sites in Brest, Ruelle and elsewhere, we are coordinating the work of some 45 companies in the region around Brest and the west of France that have been called upon to carry out with us the four million hours of work required by the overhaul, all in compliance with our safety, deadlines and quality of work specifications.”

To be supervised by DCNS with DGA and the Fleet Support Service (SSF), the adaptation work will be conducted over a period of 18 months, and will also involve an extensive refit maintenance operation.
