A submarine tracking another submarine can take advantage of its target's baffles to follow at a close distance without being detected. Periodically, a submarine will perform a maneuver called clearing the baffles, in which the boat will turn left or right far enough to listen with the forward array sonar for a few minutes in the area that was previously blocked by the baffles.
It was also used by U.S. Navy nuclear submarines to clear their sonar dead zones. [5] The Williamson turn is the most preferred maneuver by navigating officers onboard ship as it can be used in any condition of visibility and weather. The suitability of the turn depends on the situation:
Submarine escape trunk View inside a submarine escape trunk, looking up from below the lower hatch. An escape trunk is a small compartment on a submarine which provides a means for crew to escape from a downed submarine; it operates on a principle similar to an airlock, in that it allows the transfer of persons or objects between two areas of different pressure.
An early use of underwater acoustic positioning systems, credited with initiating the modern day development of these systems, [15] involved the loss of the American nuclear submarine USS Thresher on 10 April 1963 in a water depth of 2560m. [16] An acoustic short baseline (SBL) positioning system was installed on the oceanographic vessel USNS ...
Communication with submarines is a field within military communications that presents technical challenges and requires specialized technology. Because radio waves do not travel well through good electrical conductors like salt water, submerged submarines are cut off from radio communication with their command authorities at ordinary radio frequencies.
Abaft (preposition): at or toward the stern of a ship, or further back from a location, e.g. "the mizzenmast is abaft the mainmast". [1]Aboard: onto or within a ship, or in a group.

As the high-speed maneuvers finished at 13:30, Waddle called for Greeneville to perform an emergency dive (called an "emergency deep") followed by an emergency main ballast blow, a maneuver that brings the submarine from a depth of about 400 feet (120 m) to the surface in a few seconds by using high-pressure air to force the water out of the ...
