The CAPTAS 2, also known as Type 4229 or UMS 4229, is a TB system with linear receive arrays in either dependent (towed behind the TB) or independent configurations which is an optimal design for shallow water operations. The sonar system accepts full passive and active operation modes. In active operation mode the CAPTAS 2 sonar covers a frequency range between 0.95 and 2.1 KHz and is fully compatible with built-in passive torpedo alert function. In passive mode the frequency covered is below 0.1 to 2 KHz. The towing cable and handling system have been designed to minimize problems due to surface layers. Sophisticated algorithms are used for coping with the reverberation conditions of shallow littoral waters.

The CAPTAS 2 sonar TB is 2x1x1.2 (LxHxW) meters with a weight of 1,250 kg. The towed array is 90 meters in length and 85mm in diameter with a combined weight of 2,490 kg. The handling system is 6.4x2.1x4.4 (LxHxW) meters with a weight of 15,000 kg. The UMS 4229 uses Omni-directional vertical line array of two free flooded rings (FFR). The heavy tow cable is 264 meters long and the light two cable is 500 meters long. The towed array sonar can be deployed or recovered within 20 minutes and has a maximum tow speed of 30 knots.

The CAPTAS 4 (Combined Active and Passive Towed Array Sonar, 4 rings, for Surface Ship Underwater Warfare), also knwon as Type 4249 or UMS 4249, is a TB system with linear receive arrays in either dependent (towed behind the TB) or independent configurations which is an optimal design for shallow water operations. The sonar system accepts full passive and active operation modes.

The CAPTAS 4 VDS (Variable Depth Sonar) low-frequency towed array was selected by the Navies of France and Italy, along with the Type 4110 hull-mounted sonar, as part of a complete sonar suite for long-range ASW detection onboard FREMM ASW frigates.

The Thales CAPTAS 1 is a towed array sonar tailored for small and medium-sized surface combatants and patrol vessels displacing 300 tons or more and performing anti-submarine warfare (ASW) missions. The CAPTAS 1 is offered within a lightweight, modular and compact sonar suite that features lower acquisition cost, easy installation, sea-proven technologies, high reliability, robust design, low operating costs and easy to use. The system includes the Thales BlueWatcher hull-mounted sonar and the CAPTAS 1 towed array sonar to engage underwater threats. The BlueWatcher sonar builds on the FLASH dipping sonar deployed by helicopters. The new sonar suite along with CAPTAS 1 was launched at Euronaval exhibition in October 2014.

The CAPTAS 4 Compact is a smaller version of the CAPTAS 4 towed array sonar especially well suited to provide anti-submarine warfare (ASW) capabilities onboard medium-size frigates. The new sonar system is 20-percent lighter and 50-percent smaller than its parent system making possible to move the sensor package from ship to ship. The CAPTAS 4 Compact modular sonar system has been designed to fit into the new French Navy FTI frigate. Thales introduced the newest towed array sonar at the Euronaval exhibition, Paris, in October 2016.
