Kongsberg has signed a contract with Saab to provide ASW and diver detection sonars to the Finnish Navy’s Pohjanmaa-class corvettes (pictured) currently under development.
The SS2030 and SD9500 sonars are used for deployment in shallow waters and have acoustic properties.
Thomas Dahle, Director of Sales at Kongsberg, said: ‘We are very pleased to have been selected for another sonar programme for the Finnish Navy and to further strengthen our position as a principal supplier of shallow-water ASW, diver detection and mine-hunting equipment.’
Designed for ASW operations and capable of detecting torpedoes, the SS2030 is a hull-mounted sonar which is integrated with a Sound Propagation Model. This allows it to determine the optimal tilt settings to enhance the Probability of Detection (PoD) ratio.
On the other hand, the SD9500 is a light weight compact over-the-side dipping sonar with horizontal and vertical positioning capabilities.

Under Project Land 8710 Phase 2, Australia has been seeking to acquire an undisclosed number of Littoral Manoeuvre Vessels to replace the Balikpapan-class. The programme has an estimated value of AU$1.4 billion (US$910 million), with IOC slated for 2032.
The Royal Navy’s Type-23 Duke-class frigates for the UK Royal Navy were designed as anti-submarine warfare (ASW) ships but now have a multi-role function. Of the 16 Type 23s built, 12 remain in service with the Royal Navy and will be replaced by the Type-26 frigates before 2035.
The work took place under the Patrol Boat Autonomy Trial (PBAT), which has been a collaboration between Austal, Greenroom Robotics, the Trusted Autonomous Systems Defence Cooperative Research Centre and the Royal Australian Navy’s (RAN) Warfare Innovation Navy Branch.
