There will be several terms in this presentation and explaining them will make things clear. (Schwab, 250-253) There are also sound bites below.
Aft- In or near the stern of a ship.
Anechoic Tile- Rubberized tiles placed around a submarine to deaden sound on US and Royal Navy submarines.
Awash- to be just below the surface of the water.
Beam- Overall width of a ship.
Bearing- A reading off a compass of an approaching object or a direction. It is also the behavior with which sailors conduct themselves when working.
Commanding Officer- Another name for a Captain or highest ranking officer aboard a naval vessel.
Compartments- spaces divided within a submarine or ship to maintain watertight integrity.
Conning Tower- A space in a submarine above the hull containing the fire control systems for the weapons.
Control Room- The control room is where the navigation takes place when the submarine is submerged. It is a functioning bridge. Here the captain will pass orders to the crew.
Crush Depth- The depth at which a submarine will implode from ocean pressure on the hulls.
Diving planes- Panels tilted perpendicular to the length of a submarine to control depth and angle.
Engineering spaces- These include anything that involves propulsion, reactors, boilers, generators, reduction gears, etc.
Forward- Toward the bow.
Heading- Referred to as direction in relation to a compass reading.
Knot- a measure of speed of 1 nautical mile per hour (1.15 miles per hour) 23 knots= 26.45 MPH. 40 knots = 46 MPH
Littorals- An area of water close to the shoreline.
Old Salt- An experienced sailor or submariner.
Port- A window to view workings on a machine, outside or an area where some sort of connection can be made. It is also the left side of a vessel facing the bow.
Pressure Hull- The pressure hull is the inner part of a submarine's double hull designed to bear the pressure while the outer hull helps the ship hydrodynamically under water. The outer hull is usually pressure compensated by flooding when submerged.
Propulsion- The way a submarine moves through the water.
Sail- It generally has the periscopes, radar and other aids to help the submarine navigate. A sail is above the control room. It does contain a bridge that is used when the submarine surfaces.
Screw- A naval term for a propeller- usually made of bronze alloy.
Starboard – The right side of a vessel when facing the bow
Snorkel- A telescopic tube extended while the submarine is submerged at periscope depth to run the diesel engines.
Stern- The after or rear end part of a ship
Strategic Deterrence – a doctrine used during the Cold War where the US could Destroy the Soviet Union more than it could to the US. As a result, war was prevented.
Trim- The degree to which a submarine maintains neutral buoyancy. This occurs by flooding or pumping out ballast tanks.
Turbine- A turbine device to turn steam into a rotation of the screw through pressure.
Vessel- A general term for any type of watercraft.
Watch- A term for operating a vessel which differs from work on the vessel. It is governed by a high sense of alert and protocols. Bearing of crew is different.
