Submarines

Virginia class

A submarine is a sea-going vessel, both on the surface and under the water.

The primary mission of the fleet ballistic missile submarine is deterrence. By deploying these submarines, we are sending aggressor nations a message. That message is that we have nuclear and other strategic weapons on a platform that can be positioned just about anywhere in the ocean and used to retaliate against any nation that is overtly aggressive toward us or our allies.

Submarines dive by opening vent valves that allow sea water to push air out of their ballast tanks.

They were used extensively throughout the war - from beginning to end.

For modern nuclear subs, they could theoretically stay under indefinitely. Of course, there's a crew which has to eat and bathe, and food and toiletries do eventually run out.

Depending on the budget situation, typically between 3-5 years.

I can assure you that there isn't any nuclear submarine under Antarctica. The continent of Antarctica is solid land with a very thick glacier on top of it, and even if someone wanted to put a submarine underneath it, there is no way of doing that. You can put submarines in the north pole, but not the south.

What made the Civil War one of the deadliest in American history, was everyone in it was an American.

The U.S. had 111 submarines in commission at the start of World War II and commissioned 203 more before the war ended.

Machine stops listening and sends a loud BEEP. Machine starts listening again and picks up the echo. This is repeated many times as the fisher moves the boat across the sea. When the echo changes, that means the beep is bouncing off a shoal of fish. So that's the place to drop the nets in.

American submarines are not for sale. Most older ones were either scrapped or are museums (Arkansas even has one). Some older diesel-electric boats are transferred to foreign nations, but the nuclear ones never escape government control, even when dismantled.

Russian submarines are mothballed in Russian harbors, and with enough money, the right connections, and plenty of patience you might manage to buy one. Don't get any ideas of terrorizing the Seven Seas though, any Russian sub you buy will be a noisy, slow, unreliable diesel-electric boat. There's a couple in California, one in Long Beach near the Queen Mary and another in San Diego.

Yes. it is a type of SUBMARINE. The Funk and Wagnalls encyclopedia considers it to be a type of Submarine Vessel- the name comes from the Greek and means ( Deep Boat)- not deep chamber, bell, cylinder) so it goes. Bathyscaphe is often pronounced Bath-Escape which has a humorous sound. Blow Negative! even sounds like a bathroom appliance.

It depends of course on the size/class of the boat, and current ballast/weapons load, but the typical draft for U.S. Fast-Attacks is around 33'. Boomers are of course a bit deeper.

Submarines have ballast tanks inside them that can be filled with water to make them sink.

A periscope: An optical instrument that uses a series of prisms, lenses and mirrors to reflect images through a tube. Most often associated with submarines but they can also have other practical uses.
A periscope works by using mirrors to bounce light from one mirror to the other. A normal periscope uses two mirrors at 45 degrees angles to the direction you want to see. The light bounces from one to the other and then to your eye. A periscope helps you to see around corners and over walls, they are also used on submarines so that they out and see around things.

The propeller on a submarine is properly called the screw. It's a multi-bladed hydrofoil that converts the rotational energy of the shaft to propulsion. Links can be found below for more information.

During WWII, Allied warships used ASDIC (an early, crude form of Sonar), airplanes (some ships carried recoverable seaplanes), and visual lookouts (binoculars) to spot submarines and direct attacking vessels to the contact.
