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.

How many ships were sunk or damanged by Italian human torpedo submarines in the Atlantic?
A total of 14 destroyed all of these around the British naval air base at Gibraltar or near the portugeese and spanish coast, an even larger number damanged-most of these put totaly out of action.
How many navy vessels in a squadron of submarines?
During the Cold War, the count was around 12, including the Squadron's Submarine Tender and any rescue vessels assigned to the Squadron. With the decreasing fleet size, that number is around 5-8, depending on where the squadron is.
Where is the U 505 combat submarine located?
The German combat submarine U 505 is located at the Museum of Science and Industry in Chicago Illinois.
How are icebergs detected by ships?
they are detected by other ships, and then a message is passed onto other ships so the ships know to look out for iceburgs
During WWII the Finnish navy operated five small submarines, all designed in the Netherlands (by a Dutch front company) and built in Finland. Between them they sank one Soviet merchant ship and three Soviet submarines. All Finnish subs survived the war.
Where is this soviet submarine k-19 ship today?
The K-19 was decommissioned in 1991, and as of 2003 as awaiting scrapping operations to commence. Given the problems it had during its service with radiation (not uncommon aboard some older Soviet boats), it could be a while before they actually scrap it.
What are the Civil War Submarine Names?
I don't know all but i know some

What was Woodrow Wilson's reaction to the German submarine warfare campaign?
When the Germans, declared unrestricted submarine warfare, the US issued a sharp protest to this policy, saying that it was an indefensible violation of neutral rights, and threatened to hold Germany accountable. After many German offenses in the seas, Wilson threatened to break off diplomatic relations with Germany unless it abandoned its methods of submarine warfare. Wilson won a temporary victory when the Germans said that they would visit all vessels prior to attack. However, this crisis prompted Wilson to begin preparing for war (preparedness campaign). Finally when the Germans decided to declared unlimited submarine warfare on all shipping in 1917, it was impossible for Wilson to maintain US neutrality and the freedom of the seas. Thus, Wilson broke off all diplomatic relations with Germany and called on Congress to approve the arming of US merchant ships.
How did they heat a World War 2 submarine?
WWII era submarines were heated by Convection Air, direct Steam or Hot Water Radiators, and Plenum systems (forced air duct ventilation). Running diesel engines to recharge batteries on the surface were also great heaters, and still are today, though a bit noisy for most.
Why do submarine sailors get sun sensitivity?
You usually don't unless you're doing an operation that keeps you submerged for a couple of months, but if you're a hermit in port and stay indoors, it doesn't help either.
The problem stems from a lack of sunlight and fewer sources of Vitamin D while on extended operation periods of 2 or more months submerged. UV light from the sun reacts with the skin to produce Vitamin D, and a lack of it causes sensitivity.
The problem is not as prevalent as it used to be in the old submarine days of WWI and WWII; Vitamin D sources are a medical requirement aboard all Navy vessels. For submarines, the ice cream machine is typically the best source (the mix is fortified with D), since milk and fresh vegetables typically run out within 2 weeks, and preserved eggs about 6 weeks. Most crew don't like drinking the powdered milk mix (one, it tastes bad, and two, it doesn't have caffeine for long stretches where you need to be alert), and canned veggies don't offer as much nutritional value as fresh ones do.
When did the Russian submarine K-141 Kursk sink?
The Russian Navy's Oscar II-class (NATO reporting name) submarine K-141 Kursk sank as a result of an initial torpedo fuel detonation, and secondary torpedo warhead explosions (5-7), on August 12, 2000. Though 23 crew were known to have survived in the stern, they eventually perished along with the rest of the crew.
The Confederate Submarine H.L. Hunley actually sank 3 times:
August 29, 1863 - Sank during test dive preparations when dive planes were prematurely engaged.
October 15, 1863 - Failed to surface after a mock attack.
February 17, 1864 - Sank while returning to her base at Sullivan's Island, S.C., after her historic and successful attack on the Union sloop-of-war USS Housatonic in Charleston Harbor.
She was salvaged after the first 2 sinkings and returned to service; however, until she was raised in 2000, her fate remained a mystery for 136 years. Long believed to have sunk as a result of the explosion from her Spar Torpedo, that is now known to be incorrect. She is now known to have survived the attack, and signaled Confederate forces at her base on Sullivan's Island that she was returning after her successful attack on the USS Housatonic. There is strong evidence which has been found during the restoration and preservation efforts (as well as forensic examination of crew remains) that her crew did not drown as believed, but that they died from a lack of oxygen.
Submarine warfare was considered?
In the earliest days of submarine warfare, they were considered a dishonorable form of warfighting - that is, until the the honorable Navies of the world started getting their ships sunk, and finally realized the full potential of submarine warfare.
One of the provisions in the Treaty of Versailles which ended WWI was that Germany turn over all of her submarine technology to the Allies and stop building them. Hitler of course developed and built them in secret.
Unrestricted Submarine Warfare in WWI had its political backlashes, but by WW2, those worries were gone. It is similar to how snipers were originally thought of (and even today some consider sniping a dishonorable way to fight), but the psychological impact of both submarines and snipers, and the amount of resources that are used to track and destroy them, make it certain that they are a force to be reckoned with.
Any belief in those times that submarine warfare was dishonorable is history; they are considered the front lines of the Navy, often going to places before anyone else, undetected, where they can gather Intel or insert covert operations teams.
What was the name of the first American submarine?
Techically, that would be the U.S. Navy's first submarine, USS S-1 (SS-105) , built by John Phillip Holland. Though the first submarine that was used in combat, David Bushnell's Turtle (Revolutionary War), the U.S. wasn't in fact a country at that time.
The Confederate submarine H.L. Hunley was also not technically an American submarine, effectively being used by the Confederate Army (manned by Confederate sailors), but it was never a commissioned vessel in any navy.
Where did David Bushnell invent the 1776 submarine?
Bushnell developed and built the Turtle in 1775 in Old Saybrook, Connecticut.
Is 20 knots fast for a submarine in world war 2?
On the surface, twenty knots is a very good speed (maybe a little too good) for a World War 2 sub. Submerged, speed fell off considerably because the hulls were not streamlined as they were after the war. Only Germany toward the end of the war developed submarines with streamlined hulls which made them very fast when underwater. One of them was a small sumbarine which was powered by hydrogen peroxide (rocket fuel) and it could do twenty knots submerged but was extremely dangerous to operate. The other was diesel-electric with a streamlined hull and other improvements which gave it a submerged speed of sixteen knots, a very fast underwater speed for WW2.
What was the German vessels that sank many allied ships?
U-Boats are submarines. Surface raiders would be warships (primarily battle-cruisers, pocket battleships, battleships & heavy cruisers) and disguised armed merchant ships (Q-ships).
Did the 5 midget submarines successful in the Pearl harbor attack?
The midget subs did no actual damage
How long can nuclear subs stay submerged?
Many months! The biggest limitation is the amount of food they can carry for the crew. The actual limits are classified.
Submarines can produce their own air and water and with nuclear power they could stay submerged indefinitely. The limiting factor is the amount of storage space (there is not much) on a sub for food and the the size of the crew onboard that consumes it. The larger SSGN's can stay submerged longer than the SSN's because they have more storage space.
What impact did the Japanese submarine attack on Sydney have on Australians?
Australia had been attacked by air in the north at Darwin. Its pans to defend a line around Brisbane were upset by the daring attack in Sydney Harbour. This attack increased public fears of an amphibious attack on the south, but of course this could not have happened as the Japanese had run out of resources to do any out any substantial invasion. The best they had left for the invasion of New Guinea was a marine regiment in the failed attempt at Milne Bay and a scratch half-division at Kokoda.
Australia's forces were five infantry and three armoured divisions in Australia and three infantry divisions returning from the Middle East. Still, that didn't stop[ a panic over the Sydney event. Our government was not very adept at responding to psychological warfare to put it mildly.
