AN/SQQ-30 - Mine Classifying / Detecting Sonar

This variable depth minehunting sonar is the standard installation in the MCM 2-9.

The AN/SQQ-30 (originally designated the Deep Mod AN/SQQ-14) is an improved version of the SQQ-14. An actual AN/SQQ-14 sonar system was used as the starting point for each AN/SQQ-30 with various improvements made to the system.

  • A long tow cable/conductor replaced the articulated strut to enable greater search depths.
  • An electronically stabilized sonar dome is used instead of the tension stress of the articulated strut used in the MSO SQQ-14, with a compass installed in the sonar dome to provide a reference.
  • An increased vertical coverage capability is added to the sonar transducer.
  • The sonar dome is strengthened to withstand greater depths.
  • The detection and classification range capabilities remain essentially the same as in the SQQ-14.

The OK-520/SQQ deploy/recovery winch is also used with the AN/SQQ-32. The AN/SQQ-32 sonar will be backfitted into MCM 2-9 in future availabilities.
