THE MOST COMPACT SONAR OF THE HMS FAMILY TO EQUIP COMBAT VESSELS WITH A PERMANENT ANTI-SUBMARINE CAPABILITY AT A HIGHT COST-EFFECTIVENESS

  • Surveillance and self protection against multiple threats

Primarily ASW capability with simultaneous early torpedo warning. Obstacle avoidance mode.
Full capability in active and passive mode:
- Excellent active performances against AIP, nuclear submarines and midgets.
- In passive mode, complementary equipment added to radar, optical, IR sensors, capable to detect and classify some surface threats, such as fast surface ship.

  • Robust and easy to install

Lightweight and compact sonar with minimum shipyard constraints. Easiest intstallation adapted to small hulls & high speeds, suitable for noisy platform.

  • Cooperative asset

Inter-operability with most current low frequency sonar in operation worldwide (TUS Captas-1 or Captas-2/Flash)

  • Reduced operator workload

User friendly, state-of-the-art Human Computer Interface. Flexible interfaces with any CMS.

  • Integrated Logistic Support

High degree of support & continuous evolutions for inherent customer’s long term support
Highly reliable with very few installation units that easily fits with virtually any platform.

 

PEDIGREE

More than 150 Hull Mounted sonar systems have been already ordered

 

OPERATIONAL HIGHLIGHTS

BlueWatcher is a robust and compact product designed to be used in various geographical zones (from cold to hot waters) and in adverse environmental conditions (up to sea state 6).

BlueWatcher is a perfect HMS to cooperate with a TUS Captas-1 VDS, thus providing the most performant compact ASW Sonar Suite of the OPV market. Excellent balance between performance and space requirements.

Enhancements to the basic system: performance prediction, recording unit, sonar operator console, UW telephone.

 

MAIN CHARACTERISTICS

Built on an open system architecture offering the best compromise with re-use of sea proven functionality, state-of-the-art software COTS technologies. Off-the shelf solution, based on existing building blocks, ensuring short timely delivery, through life upgrade and refresh technology.
