Damn! And I thought the AN/SQS 26 was a behemoth! It had only 18 or so cabinets of equipment -- not counting LAPS and the stuff in the xducer.

I'm not sure if it's the same as when you were in, but Sonar Division (aka Combat Acoustics Div) had the most spaces of ANY division on the ship. TOO MANY SPACES, if you ask me.....somebody had to keep them clean.
Now, for the rest of you wondering what Goat and I are talking about:
AN/SQS-53 Sonar
The Sonar Set AN/SQS-53C is a computer-controlled surface-ship sonar that has both active and passive operating capabilities providing precise information for ASW weapons control and guidance. The AN/SQS-53C is designed to perform direct path ASW search, detection, localization, and tracking from a hull mounted transducer array. The AN/SQS-53C retains the transducer assembly from either the AN/SQS-53A or 53B. The AN/SQS-53C provides greater range and detection capability with only half of the electronics footprint and less weight than earlier versions. The AN/SQS-53C is equipped with high source level, fully stabilized beams, and wide convergence zone annuli coupled with computer-aided detection and automatic contact management. Implemented in standard electronic modules, the AN/SQS-53C is an all digital system with stable performance, on-line reconfiguration in the event of a component failure, and performance monitoring/fault location software to quickly isolate failures. The AN/SQS-53C provides apparent range, bearing, and true bearing of contacts when employing active sonar and provides true bearing of contacts detected by passive means.
The AN/SQS-53 is the most advanced surface ship ASW sonar in the US Navy inventory. It is a high-power, long-range system evolved from the AN/SQS-26CX, used actively and passively to detect and localize submarine contacts. The SQS-53B, located in a large dome at the bow of the ship, will detect, identify, and track multiple underwater targets. With its higher power and improved signal processing equipment, this sonar is the first in the Navy to be linked directly to digital computers, thus ensuring swift, accurate processing of target information. Functions of the system are the detection, tracking, and classification of underwater targets. It can also be used for underwater communications, countermeasures against acoustic underwater weapons, and certain oceanographic recording uses. The analog receivers of the AN/SQS-53A/B hull mounted sonars are being upgraded to digital by the use of Commercial-Off-The-Shelf (COTS) processors, and are redesignated SQS-53D.
This system is the basic sonar watchstanders tool to keep an eye on all traffic; often picking up surface ships at greater range than most radar systems. It can detect, identify and track multiple targets and is the first USN surface ship sonar designed specifically to interface directly with a vessel's digital computers. It has three active modes of operation; Surface duet, Bottom bounce and Convergence zone. The number of Third World countries that can employ wake-homing torpedoes from short ranges (Littoral Warfare) has grown steadily since the end of the Cold War. Sensors such as the AN/SQS-53C/D will be able to detect these platforms before they are able launch these weapons. It is also used to ping off of buoys for own ship location purposes in a foreign port.
