After successful tests with a U.S. submarine using a test array at Eleuthera the Navy ordered six LOFAR systems for installation. The shore stations where the operational array and cable, composing a surveillance sonar set, terminated, were given the generic and non revealing term Naval Facilitity (NAVFAC).
On the submarine force side, there was a recurrent idea that SOSUS/IUSS could not detect U.S. submarines, despite early SOSUS having tracked USS George Washington across the Atlantic. The realization that SOSUS could detect U.S. nuclear submarines led to the Navy's quieting program for those submarines and the assumption returned.
AN/SQS-53 is an improved version of AN/SQS-26CX. The main difference between the SQS-26CX and SQS-53 sonars is the digital computer interface with the Mk 116 anti-submarine warfare (ASW) weapon control system in the latter. [4] In addition, AN/SQS-53 sonar can be fitted with the Kingfisher small obstacle (mines) avoidance sonar. [4 ...
1 Main Circuit (1MC) is the term for the shipboard public address circuits on United States Navy and United States Coast Guard vessels.This provides a means of transmitting general information and orders to all internal ship spaces and topside areas, and is loud enough that all embarked personnel are (normally) able to hear it.
Submarine detection systems are an aspect of antisubmarine warfare. They are of particular importance in nuclear deterrence , as they directly undermine one of the three arms of the nuclear triad by making counter-force attacks on submarines possible.
The DUBV 43C towed array sonar of La Motte-Picquet.. A towed array sonar is a system of hydrophones towed behind a submarine or a surface ship on a cable. [1] Trailing the hydrophones behind the vessel, on a cable that can be kilometers long, keeps the array's sensors away from the ship's own noise sources, greatly improving its signal-to-noise ratio, and hence the effectiveness of detecting ...
