Thales delivers the first CAPTAS-4 sonar for the US Navy

29 April 2024

The first CAPTAS-4 variable-depth sonar transmitter has been delivered to the U.S. Navy’s Constellation Frigate Program (FFG-62) by Thales' subsidiary Advanced Acoustic Concepts (AAC).

The system was delivered on October 12, 2023, ahead of contractual milestones while under very aggressive time constraints. Thales’ sonar technology was chosen by Fincantieri Marinette Marine, in agreement with the U.S. Navy to equip its new frigates. In addition to the two systems already ordered to date, up to eight additional CAPTAS-4 transmitters assemblies could be supplied under the current contract. In this perspective, AAC will soon complete construction on a new CAPTAS production facility located at their current site near Uniontown, Pennsylvania, where final assembly, integration and acceptance testing will occur for shipsets two through 10.

Thales has more than 50 years’ experience in underwater warfare and is the world’s leading sonar exporter. The CAPTAS family comprises a series of low-frequency variable-immersion sonars dedicated to anti-submarine warfare. The CAPTAS-4 delivered to the U.S. Navy is the most powerful of the CAPTAS family. It has been tested under a wide range of operational conditions for instance by the French, British and Italian navies, and its technical maturity and performance are recognized the world over.

In 2020, 2021 and 2022, several French multi-mission frigates equipped with the CAPTAS-4 system won the prestigious Hook’Em Award, the American prize for excellence awarded to the best crew performance in the field of anti-submarine warfare, during coalition exercises in the 6th Fleet area of operations. Thales was singled out and recognized for the excellence of its know-how, for the ability of its sonar systems to detect, locate, classify and pursue increasingly stealthy and silent threats under the sea.
