Kongsberg Maritime will deliver the ST2400 Variable Depth Sonar (VDS) system to the Royal Swedish Navy as part of Saab’s mid-life upgrade of the Göteborg-class corvette fleet, the company announced on 19 October.

The VDS will enhance the corvettes' anti-submarine warfare (ASW) capabilities for operations in the Baltics.

The ST2400 VDS is designed to detect submarines, mines and unmanned underwater vehicles in littoral waters.  The medium-frequency sonar improves performance and operations in shallow waters. With compact design, it features omni and sector transmission, electronic map overlay, sound propagation model, advanced tracking and detection, as well as a built-in simulator for training.

The system overcomes traditional towed array sonar issues with ambiguity, buoyancy and omni coverage, and can be rapidly deployed for high speed manoeuvring and dipping mode.

Thomas Hostvedt Dahle, director of sales for subsea and naval sonars at Kongsberg Maritime, said: ‘We are pleased to strengthen our position within littoral ASW and especially in the Baltics and in Sweden

‘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. The ST2400 VDS is unique as it is a compact package with coverage and performance that can overcome challenging acoustic environments while not limiting a ship's manoeuvrability.’
