Kongsberg has signed a contract to supply new passive sonar processing systems (PSPS) as part of the sonar suite modification project for the four Walrus class submarines of the Dutch Navy.

The contract was made between the Dutch Defence Materiel Organisation (DMO) and Kongsberg, represented by the naval systems and surveillance division.

The Passive Sonar Processing System (PSPS) is integrating hydrophone data from all the passive sonars aboard into one processing system. This PSPS integration technology has proven to produce more accurate target solutions in shorter time by utilising the full potential of the sonar suite, and giving the sonar operators flexibility to use passive sonar data from any combination of sonars to solve their tasks. The PSPS to be delivered will take full advantage of the sonar system upgrade solutions that have been developed and are in production for the Norwegian Ula class submarines.

“Kongsberg has, for more than 40 years, developed and supplied submarine systems to Norwegian, German and Italian submarines. This contract for the sonar suite modification project to the Dutch Walrus class submarines was won in open international competition and again demonstrated Kongsberg’s capability to meet customer’s requirements in a flexible and cost effective way in a demanding submarine upgrade market. There exists in the world market a large number of submarines in need of a mid-life, or life extension, update. In this context this is yet another important reference contract for Kongsberg that will further strengthen our position as a supplier of integrated submarine systems”, says executive vice president Nils-Oddvar Hagen in Kongsberg Defence Systems.
