Patria will design and deliver new anti-submarine warfare (ASW) sonars for the Finnish Navy’s Pohjanmaa class corvettes.

The company was awarded a contract for the work by Saab, the Squadron 2020 combat system contractor.

The new lightweight dual-tow Sonac DTS system consists of both an active variable depth sonar and a passive towed thin-line receiving array that can be used together or independently. The system has been designed to meet the demanding acoustic underwater environmental conditions of the Baltic Sea.

Jonas Geust, president of Patria’s systems business unit, said: ‘We are proud to provide the new Pohjanmaa class corvettes with one of their main sensors representing critical technology from the national security of supply point of view. The development of the Sonac DTS system is based on Patria’s over 30-year experience in the design and delivery of underwater acoustic sensor systems.’
