Hovering is a precise maneuver, and is typically used by boats in preparation for surfacing through the ice, or for vertical missile launch ops where a stationary platform is required.
Hovering requires precise trim ballast tank control. Trim tanks are used to maintain Neutral Buoyancy while submerged, as well as to compensate for buoyancy and variable ballast changes when moving through depths or different temperature zones in the ocean. Once the boat is at an all-stop bell, the Ballast Control Panel (BCP) operator (the Chief of the Watch) will bring in or pump out the required amount of water from the trim tanks to hover. This can be tricky when you're trying to surface under the ice through a polynya (thin ice pond) as currents can move you when you move from a hovering/stationary position at depth to a slow ascent. It's not uncommon to get pushed into thick ice while making the transition.
For vertical launch missile ops, the boat must re-hover after a launch to regain a stable platform.
They don't hover, they swim
The new depth of the submarine is at -43.75 meters.
The submarine was at a depth of 3,000 feet.
depth
The military submarines maintain depth by use of the planes. As they move through the water, a little up or down "tilt" on the planes will keep the boat at the correct depth.
The depth of a submarine under the sea means how many feet below the surface of the sea it is.
their floating at a depth
It varies by the type of submarine. United States, Russia, United Kingdom, China, France, and India are examples of nations who have or are assumed to have nuclear submarine capabilities.For security purposes, governments don't give out full specifications on their weapons of war, especially on something as big, expensive, and instrumental as a submarine. The true depth information is classified, probably above "Top Secret". For the general US submarine fleet, the "official" answer is typically around 600 feet. (According to one Navy instructor it was changed from 400 feet when a documentary was aired accidentally showing footage of the depth meter at a depth of around that depth.)Any Navy in the world who operates a nuclear submarine is going to publish a low ballpark figure in the name of national security and secrecy. If everyone knew the exact depth a submarine could submerse to, it'd be easier to kill them. Wikipedia says a Soviet/Russian class Alpha submarine may have successfully operated at a depth of 4,300 feet. But rest assured whatever the published depth of submarine is, it many times greater than that.
600 ft is threshhold
The total change in depth is -144 feet.
Landmines are positioned under earth and leaves. A mine for a submarine hangs in the water below the water surface, or is ejected from a ship's deck to float down to the depth of the submarine.
The submarine will be at a depth of 255 meters. We work it by 230 - 95 + 120 = First, 230 - 95 = 135, and 135 + 120 = 255 meters
