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.
A crash dive is a maneuver by a submarine in which the vessel submerges as quickly as possible to avoid attack. Crash diving from the surface to avoid attack has been largely rendered obsolete with the advent of nuclear-powered submarines, as they normally operate submerged. However, the crash dive is also a standard maneuver to avoid a collision.

However, according to Uncommon Carriers by John McPhee, the maneuver was originally called the "Butakov pipe" and was used in the Russo-Japanese War as a way of keeping guns at the same distance from an enemy. [4] It was also used by U.S. Navy nuclear submarines to clear their sonar dead zones. [5]
USS Greenfish after GUPPY III modernization. Visible on deck are the three distinctive shark-fin domes of the PUFFS sonar.. The Greater Underwater Propulsion Power Program (GUPPY) was initiated by the United States Navy after World War II to improve the submerged speed, maneuverability, and endurance of its submarines.
Submarine navigation underwater requires special skills and technologies not needed by surface ships. The challenges of underwater navigation have become more important as submarines spend more time underwater, travelling greater distances and at higher speed.
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.
A total of eight individual airtight chambers comprise the FC470. The main hull or gunwale contains five intercommunicating chambers, which are separated by internal baffles and valves. This means that a single leak will not result in loss of pressure throughout the boat, and that air can be bled between chambers to compensate for loss in one.
