AN / SQS-53 of the US cruiser USS Cowpens (CG-63)

The SQS-53 is the most powerful sonar device that the US Navy uses on surface vessels. Basically, it's a further improved version of the AN / SQS-26CX . However, since it is compatible with new anti-submarine systems, it was decided to use a new name. The sonar itself is usually in a hard rubber - bulbous bow housed. The system works in the low frequency range and offers 360 ° surveillance and is part of the AN / SQQ-89 submarine hunting system .

variants

  • AN / SQS-53A : The basic model
  • AN / SQS-53B : Thanks to improved computer systems, the SQS-53 is the first American sonar that could be fully integrated into the ship's digital combat systems. Furthermore, it can now be used for underwater communication ( "Gertrude" ) and as an active countermeasure against acoustically guided torpedoes. The reliability of the system was also increased.
  • AN / SQS-53C : Extensive modernization of the electronics cut space requirements in half and, at the same time, significantly increased system performance. Further improvements to the sonar components now allowed the simultaneous tracking of multiple targets, taking into account a larger reception bandwidth and the simultaneous use of active and passive sonar. Furthermore, the reliability and the transmission power in active operation have been increased.
  • AN / SQS-53D : In this version, many computer systems were new and more powerful COTS - hardware replaced.
