Thales, Leonardo to Support Polish Navy’s ASW Capability with FLASH SONICS Sonars

The Polish Navy will rely on Thales to equip its four new Leonardo AW101 helicopters with FLASH SONICS sonars, Thales announced.

The key benefits of this low-frequency wideband dipping sonar include long-range detection with broad sector coverage and low false alarm rates in open ocean as well as littoral waters. Associated with an active and passive sonobuoy processing system, FLASH SONICS provides an unparalleled anti-submarine warfare (ASW) capability. Initially designed for heavy helicopters such as the Merlin AW101 from Leonardo chosen by the Polish Navy, the system is also available in a compact version equipped with an electric motor for lighter helicopters like the AW159.

Thales and Leonardo have worked jointly with local industry partners, including the Polish aerospace and defence equipment manufacturer WZL1 and the Gdansk University of Technology (GUT), to meet the customer’s requirements. This cooperation demonstrates the Thales Group’s commitment and ability to build and maintain long-term partnerships with local players. GUT and WZL1 will benefit from transfers of technology for sonar maintenance on this programme.

“The FLASH system has been proven in operational deployments with numerous navies, making it a formidable threat for all types of submarines. It is an important instrument of operational superiority for our client navies in their anti-submarine warfare operations. We are very appreciative of the trust the Polish Navy has placed in us with this new contract in partnership with Leonardo, which further consolidates the Group’s world leadership position in anti-submarine warfare systems.” Alexis Morel, Vice President, Underwater Systems.

The FLASH system (Folding Light Acoustic System for Helicopters) is currently the leading dipping sonar on the international market and has become the benchmark system for the world’s major navies.

The FLASH dipping sonars provide a first-rate level of protection that is recognised by a large number of naval forces, including the US Navy, the UK Royal Navy, the French Navy, the Royal Australian Navy and the navies of the United Arab Emirates, Norway, Sweden, South Korea, the Philippines and now Poland.

To date, over 400 Flash systems have been delivered to about a dozen navies around the world.
