In a joint statement, Danny Pronk, projects procurement officer, and Jaap Hagesteijn, senior naval systems integrator, representing the Dutch Defence Materiel Organisation (DMO) which was in charge of the selection process, said: “We chose Safran Electronics & Defense because we have great confidence in their long experience as a supplier of naval equipment. Their system’s performance and reliability, as well as customer support, were also decisive factors in our selection.”

Following the contract signature, Jean-Christophe Mugler, head of sales & marketing in Safran Electronics & Defense’s Defense Division, added, “We are very proud of this selection, which recognizes our position as a favored supplier to Walrus class submarines. We will continue to deliver top-flight service to the DMO, whose selection once again illustrates our outstanding expertise in this field.”

Safran Electronics & Defense’s Sigma 40 is the best-selling naval inertial navigation system in the world. Inertial systems from Safran Electronics & Defense are deployed by more than 40 navies worldwide.

The Walrus-class submarine is the only submarine class currently in operation in the Royal Netherlands Navy. Four are commissioned since the 1990ies. They have a submerged displacement of 2,650 tons and a length of 67.7 meters.
