    Initially the SURTASS system were passive, receiving only sonar systems. The array was towed miles behind the ships and were designed for long range detection of submarines. As the passive systems were being deployed, an active adjunct known as the SURTASS Low Frequency Active (LFA) systems was designed for long range detection.

    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 ...

    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.

  6. Towed array sonar - Wikipedia

    en.wikipedia.org/wiki/Towed_array_sonar

    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 ...

  7. SOSUS - Wikipedia

    en.wikipedia.org/wiki/SOSUS

    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. [15]

    During World War II, he continued to develop sonar systems that could detect submarines, mines, and torpedoes. He published Fundamentals of Sonar in 1957 as chief research consultant at the US Navy Underwater Sound Laboratory. He held this position until 1959 when he became technical director, a position he held until mandatory retirement in 1963.
