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).
AN/SQS-26 was a United States Navy surface ship, bow mounted, low frequency, active/passive sonar developed by the Naval Underwater Sound Laboratory [1] and built by General Electric and the EDO Corporation. At one point, it was installed on 87 [2] US Navy warships from the 1960s to the 1990s and may still be in use on ships transferred to ...
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.
Passive Underwater Fire Control Feasibility System (or Study) (PUFFS) is a passive sonar system for submarines. It was designated AN/BQG-4 and was primarily installed on United States Navy conventional submarines built in the 1950s beginning with the Tang class , and also those converted to GUPPY III or otherwise modernized in the 1960s.
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 French entity, Thomson Sintra, brought in by Thomson-CSF, was the European leader in defence-related sonar systems and the world's second after Lockheed Martin Loral, with annual sales of 1.5 billion francs, split between submarine sonars (35%), anti-submarine warfare systems (27%), airborne sonars (18%) and mine warfare (15%).
Asdic was the British version of sonar developed at the end of World War I based on the work of French physicist Paul Langevin and Russian engineer M. Constantin Chilowsky. The system was developed as a means to detect and locate submarines by their reflection of sound waves.
USHUS is a multipurpose integrated sonar suite used for detecting and tracking enemy submarines, surface vessels, and torpedoes as well as for underwater communication and obstacles avoidance operations. The sonar capabilities of includes active and passive sonar surveillance, underwater communication and is capable of interception and.
