Thales has signed a five-year contract with the UK’s Ministry of Defence to provide support for the Sonar 2050 anti-submarine sensor used on the Royal Navy’s Type 23 frigate fleet.

Sonar 2050 is a medium-range bow sonar currently fitted to thirteen Type 23 frigates and is the Royal Navy’s primary hull-mounted antisubmarine warfare sensor. It also provides the ship with passive detection capabilities at lower frequencies. Under the contract, Thales will provide physical support of Sonar 2050 for operational defect rectifications, a worldwide 24/7 helpdesk support service, dry dock and afloat support, and test equipment and handling.
