Thales wins delivery order for repair of assembly on H-60 ALFS Sonar Dome

Thales Defense and Security is being awarded a delivery order for the repair of one weapon repairable assembly on the airborne low frequency sonar system (ALFS) Sonar Dome, which is required to support the H-60 helicopter.

The delivery order, worth around $7.7 million, was awarded by the U.S. Naval Supply Systems Command Weapon Systems Support (NAVSUP WSS) located in Philadelphia, Pennsylvania. Fiscal 2018 working capital funds (Navy) in the amount of around $3.8 million will be obligated at the time of award.

The work will be performed in Clarksburg, Maryland (50 percent); and Valbonne, France (50 percent). The work is expected to be completed by December 2019.

 AN/AQS-22 Airborne Low Frequency Sonar (ALFS) 

The AN/AQS-22 Airborne Low Frequency Sonar (ALFS) is the primary undersea warfare (USW) sensor of the MH-60R multi-mission helicopter.

This integrated dipping sonar system, weighing 272 kg, enables the MH-60R to accomplish the assigned anti-submarine warfare (ASW) missions of submarine detection, tracking, localization and classification. It also performs missions relating to acoustic intercept, underwater communications and environmental data acquisition.

Power to the AN/AQS-22 ALFS is supplied by the helicopter, eliminating the need for expensive in-unit sonar batteries.

Raytheon, in partnership with Thales Underwater Systems, produces an average of 20 full-rate AN/AQS-22 production systems per year. Additionally, Raytheon provides the full range of whole life services and support including spares, repairs and field service support.
