Saab has selected Kongsberg Maritime to supply naval sonars for the mid-life upgrade of the Royal Swedish Navy’s Göteborg-class corvettes.
Kongsberg is set to supply ST2400 varial depth sonar (VDS) systems under the deal, which are expected to strengthen the Göteborg-class corvettes’ anti-submarine capability during operation in the Baltics.

The medium-frequency sonar is capable of detecting submarines, mines and unmanned underwater vehicles in littoral waters.
It is also claimed to offer omni and sector transmission, electronic map overlay, sound propagation model, advanced tracking and detection, as well as a built-in simulator for training purposes.
The ST2400 VDS weighs less than three tonnes and can be rapidly deployed for high-speed manoeuvring, in addition to full stop (dipping mode).
Kongsberg Maritime Subsea Naval Sales director Thomas Hostvedt Dahle said: “The Royal Swedish Navy has seen the ST2400 VDS in action on our test vessel in Horten (Norway) and experienced its capabilities already operated by the Finnish Navy in Baltic exercises.

By GlobalData“The ST2400 VDS is unique as it’s a compact package with coverage and performance that can overcome challenging acoustic environments, while not limiting a ship’s manoeuvrability.”
Kongsberg Maritime’s naval sonars for anti-submarine warfare and mine hunting are based on its portfolio of technologies for subsea activities in offshore, seismic and merchant marine applications.
Saab previously signed a new Skr1.249bn ($152.4m) contract with the Swedish Defence Materiel Administration (FMV) for the modification and modernisation of the Swedish Navy’s Gävle-class corvettes in July.
The company will be responsible for extending the life of two Gävle-class corvettes, HMS Gävle and HMS Sundsvall, under the deal.
