Submarines
Submarines are naval craft that can operate for an extended period of time underwater. They are used primarily as warships, as well as for business, scientific and other purposes. Submarines are different from submersibles, which only have limited underwater capability.

What do you call people who drive submarines?
Well this depends on what type of submarine you are talking about. On the 688 class they are called Helm and Planesman. In the newer classes such as the Virginia they are called Pilot and Co-pilot
There were subs in the 19th century, but they were really a part of naval warfare from World War One to the end of the Cold War. If large scale war breaks out in the near future, expect submarines to be a huge factor on the ocean front.
How many people does it take to operate a submarine 1000sq. used to drill oil?
Modern research submarines can usually carry two, three or four. There are anywhere from about 100 people on a U.S. Navy attack submarine to over 200 on one of our fleet ballistic missile boats. And some of the small early WWII boats had crews of something on the order of 60 or so. The Japanese used 2-man subs at Pearl Harbor. Bottom line: the number of crew required to operate a submarine varies with the type of boat. Need a link? You got it.

You can't base surface wave action ability to affect a submarine based on wavelength or even height alone. It depends entirely on the dynamics of the surface wave action as it's affected by the weather, the size/type of the submarine involved, and a slew of other ocean environment variables. A smaller boat will be affected by wave action at depth more easily than a larger one will.
Of course I'm sure there's some classroom Oceanographer/Professor/High School teacher with no real-world submarine experience somewhere who thinks it's possible to calculate it without minor variables like submerged displacement, propulsion type and speed (DE or Nuclear), depth of the boat in question, density of the water (e.g., in or out of the Gulf Stream, or in the Arctic, where salinity is less), temperature, wind speed, storm action, etc.
Intense storms can have a significant effect on submerged submarines at even 400' and below. I remember in particular a remnant of a hurricane as we were headed home to Charleston in 1983. We were at 400', taking 12-15 degree rolls due to the intense wave action on the surface. Mother Nature is not friendly when she's angry.
What were the problems with submarines?
According to the commander of the nuclear submarine Skate, older submarine engines required oxygen to operate (diesels); therefore, they were only good for surface running. Underwater, submarines ran on batteries which didn't last for a long time. Admiral Hyman Rickover was the driving force in the 1950s behind putting nuclear reactors in submarines. This made the feats of the Nautilus and the Skate in August 1958 possible. Read Surface At the Pole by Commander Calvert.
Could submarines fire torpedos underwater?
Yes. The idea of the submarine is the element of surprise. Before nuclear power submarines ran on either battery power or diesel power. Every so often it needed to surface (or use a snorkle - no kidding, it's called a snorkle) to run the diesel (which would both propel the sub and charge the battery) Now, with nuclear power, the submarine can stay underwater as long as there is food for the crew. A submarine nuclear reactor can last for years.
Modern submarines are powered by a nuclear reactor. Others are powered by diesel engines while they are on the surface and batteries while they are submerged. The older ones that were powered by diesel and batteries had their limitations. While they were on the surface running on diesel engines they left a trail of exhaust smoke which gave away their position. When they were submerged and running on batteries they could only last so long and then they had to come to the surface, run the diesel engines and recharge the batteries. The submarines that are run by nuclear power do not have to resurface for a very, very long time.
Who invented the submarine and when?
Cornelius Drebbel built the first workable submarine in 1620 using the 1578 plans of English mathematician William Bourne. The frame was constructed of wood, and it was wrapped with waterproof leather.
The first submarine to be used in combat was the Turtle(also called the American Turtle). It was invented by David Bushnell in 1775 and first used in on September 6, 1776 against the HMS Eagle. It was never successful as a combat weapon.
The first submarine to sink an enemy ship was the Confederat submarine H. L. Hunley. It was built by H. L. Hunleyand successfully sank the USS Housantonic on February 17, 1864.
American David Bushnell built the TURTLE in 1776; it was piloted by Sgt. Lee of the Continental Army.
This would be a convoy. They were limited to the speed of the slowest ship. They used a zig zag pattern to make it difficult for the submarines to get a firing solution against them.
Are there current submarines in the Bering sea?
The Bering Sea is fairly shallow, but yes, submarines transit the Bering Sea regularly heading to and from the Arctic.

How was hunley the submarine protected until is recovery?
It wasn't - the Hunley was found to be very well preserved under the silt of Charleston Harbor, fully covered with and full of silt and mud. The visibility at the site was near zero. She had survived 45 tropical storms/hurricanes since her sinking. There was more concern that a tropical storm might hit during the recovery phase.
The biggest obstacle was designing the lifting apparatus and coming up with recovery procedures that would raise the Hunley intact, and at its angle of sinking. This was to preserve and prevent the boat from shifting, which might cause the rivets to pull out, shifting anything inside.
What sort of radars do submarines have?
If a submarine has a radar at all, it is generally a smaller, low power unit. The most modern subs don'e have any radar gear on them at all. The signal from a radar unit can be detected by modern countermeasures equipment, and that locates the user of that radar. Bad news for a submarine, a vessel that is designed to operate in or from hiding.
Why submarine made up of strong material?
A submarine is made from strong material so it can withstand the tremendous pressure at depths.
How much does a submersible cost?
The cost of a submersible will vary by a huge amount, depending on specification.
Anything from a few thousand dollars to many millions.
What is the device used on submarines?
Which device?
More:
The modern submarine has hundreds of devices on-board used for anything imaginable. Most devices have back-ups. The nuclear reactor has a back-up diesel. There are at least 2 primary propulsion plants. Even the distiller has a smaller back-up. The distiller is the second most important device to an underway crew. Without it there is not enough water for showers. Moral would plummet and no one likes a smelly shipmate.
What was the Submarine ratio in the pacific war?
The US Navy operated about 300 subs during WWII; some source's state 288, some say well over 300. Nearly 60 of the old S boats and 77 Gatos and over a 100 Balao class, then some newer ones towards the end of the war. Those lost were about 20 Gatos, about a dozen Balaos and about twenty S boats. USN subs operating in the Atlantic were mostly shake down and training cruises, before deploying to the Pacific.
IJN subs may have been over 100, mostly I-Boats, but only two or three I-400 class were built (the largest in the world, until nuclear submarines were built). I-400's were actually under-water aircraft carriers. IJN mini-subs were carried on the decks of mother subs, and didn't cruise the oceans like the I-Boats...so actually they're in a different class of their own. But their numbers, went well over a hundred...less steel and instruments to consume and more could be built; which is why the DKM (German Navy) built submarines instead of surface warships during WWII (less steel to consume, more bang for the buck).
While the DKM pursued commerce warfare and the IJN fought a fleet war during WWII, the USN was STRONG enough to fight both types of warfare: The US Silent Service sunk both merchant ships and warships, pursuing BOTH equally.
ANS 2 - According to many sources I look up, the US Navy had 288 submarines during the war - but figures like this in wartime can always be confusing . - For instance did they mean all operational submarines or include ones just commisionned but not yet in action and so on. these kinds of figures can always be misleading. My sources also state in most case that the IJN actually had 181 submarines operational.
How many subs were lost during World War 2?
Most subs that were lost we're on Germany's side because they employes the most subs, and after the code was broken subs began sinking on the German side routinely.
What companies are building remote control submarines?
Remote control submarines are being built by Shenzhen Oida Electronics and Gemini Ind Ltd in China. They are also manufactured in kit form by Alexander Engel KG of Germany.
What Submarines sunk since world war 2?
None in war, plenty during target practice...USN lost at least two in accidents during the 1960's (USS Thresher and USS Scorpian); the USSR lost several to accidents but will only confess up the two or three of them.
Why do submariners not get decompression sickness when they surface?
Because the pressure inside a submarine is the same as at the surface. In otherwords, they never experience any pressure increase on their body since the submarine is protecting them.
Can you go on a submarine if you are pregnant?
There's no reason you should not be able to. Most submarines are pressurized in a manner similar to airplanes. Obviously, if you are expecting soon, being on a submarine makes it slightly more difficult to get medical care.
