A submarine (or sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) [2] The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub).
To express the linear depth in water accurately, the measurement should be in meters (m). The unit “meters of sea water” (msw) is a by definition a unit for measurement of pressure. Note: A change in depth of 10 meters for a change in pressure of 1 bar equates to a water density of 1012.72 kg/m 3 [citation needed]
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.
the action of a submarine of diving below the surface of water; Submerge, Submerged, or Submersed may also refer to: Submerge, ...
The first submarine in the class, Sōryū, was launched on 5 December 2007 and delivered to the navy in March 2009. The eleventh of the class is the first one that is equipped with lithium-ion batteries without a Stirling engine. [16] This submarine may have a range from AIP of 6500 nautical miles and can remain submerged for 40 days. [6]
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.
anti-submarine net. Also anti-submarine boom. A heavy underwater net attached to a boom and placed so as to protect a harbor, anchorage, or strait from penetration by submerged submarines. apeak More or less vertical. Having the anchor rode or chain as nearly vertical as possible without freeing the anchor. [citation needed] aport
Subsea technology involves fully submerged ocean equipment, operations, or applications, especially when some distance offshore, in deep ocean waters, or on the seabed. The term subsea is frequently used in connection with oceanography, marine or ocean engineering, ocean exploration, remotely operated vehicle (ROVs) autonomous underwater vehicles (AUVs), submarine communications or power ...
