Submarines

No, women aren't eligible to serve on board US Submarines.

In the purple corner🤣🤣🤣💜🤣🤣🤣

Submarines will retreat to the depths if they are detected by radar. Note that radar can only detect a submarine if they are on the surface or if they have a mast or periscope sticking up out of the water. Radar has a terrible time trying to penetrate water, so if a submarine is detected because something is sticking up out of the water, the submarine will submerge to get some depth. Radar can't detect it down there. Also, the submarine will be trying to get out of the area and become "lost" in the ocean where it cannot be detected or located.

they sank the cruise ship because the thought it was carying aminition.

I can't remember his name. but he is a American. Anyway, he made submarine at the revolutionary war (USA to UK) to win. At that time UK had a very strong NAVY, So it was very unfavorable to America that's why he made a submarine to break the UK's navy

Most Are Used For Spying And Stuff.

In general, by torpedoing their enemy's ships. Missile-carrying submarines may be loaded with either nuclear- or conventional- warhead missiles; and carry torpedoes. Conventional submarines are armed only with torpedoes; and some modern types are designed primarily to seek and sink enemy submarines. In WW2 the German U-boats hunted in "wolf-packs" to destroy Allied merchant shipping in convoys across the N.Atlantic. One even managed to creep into the St. Laurence seaway and sink a ship there - former U-boat officers have remarked that the Americans at the time had no concept of black-out precautions, making their task a lot easier. The U-boat attacks on convoys stopped only when advances in anti-submarine warfare raised the attrition rate for the Germans to an unacceptable level. The Nazi's Enigma code machine found by the Royal Navy was the one fitted to a captured U-boat; but most U-boat losses were by sinking by depth-charges.

In the American submarine force their are two types of missiles:

1. Tomahawk® Land Attack Missile (TLAM)

2. Sea-launched ballistic missile (SLBM)

A multiple independently targetable reentry vehicle (MIRV) warhead is what is deployed on a SLBM. The TLAM can carry a conventional warhead or a single nuclear warhead.

Because thin metals will crush under extreme depth

It is clearly ( Eyes Only) and not public knowledge- given the very secretive nature of submarine missions- all transmissions are probably in pre-cut ( and sped faster than even a skillful manual telegrapher could send) Morse code and are decoded by automatic decoding machines. Certainly the freqs involved are secret.

Civilian-Under water research. Military-Stealth

The USS Nautilus (SSN-571) was the US Navy's first nuclear powered submarine.

the word in German is Unterseeboot -- literally, boat under the sea. The informal name for the vessels are U-Boat.

As regards military submarines meant as warships, the Russians built the submarines with the deepest diving capability, but U.S. submarines generally make less noise.

It depends on the parts or task in question; if they're small enough to be maintained and repaired by the crew or by contractor/shipyard support teams (about 98% of the time), they're maintained/repaired in place, with parts brought in through the appropriate hatchway (e.g., for the Main Engines or the Diesel Generator on a nuclear powered boat, or the Main Diesels for a DE boat)

For major engine work or replacement requiring engine removal (shipyard or floating drydock), hull cuts are made at a specific location, and the engine is lifted out by crane and moved to a repair location. Such occurrences are rare, and typically only performed during the boat's normal overhaul cycle.

It's quite a sight to see large sections cut away into the hull of a submarine in drydock, and even more amazing to see the inside hull with all of its equipment and systems removed.

On the newer class submarines that don't employ optics, they're called "Photonics Masts". But it's still a Periscope.

Through an air and water tight door called a hatch. These hatches are typically thick, round and rounded metal to withstand the sea water pressure at depth.

There were no "Islanders" in the fight against German U- boats. This fight was carried by the Canadian Navy, Royal Navy and British , Canadian and US Air forces.

Absolutely - there are few sounds more distinctive than that of a torpedo in the water on Sonar.

Modern Submarine sonar can detect torpedoes in the water by their main sonar arrays, as well as torpedo detection systems. Quick reaction, speed, countermeasures, and constant, precise torpedo sonar bearings are key for evasion, though with most modern homing torpedoes, if it gets a lock on you, you're history. Modern torpedoes use both active and passive sonar to detect, lock on and track their targets, and some are even wire guided - meaning that if it misses, the Fire Control tech monitoring the torpedo can steer it manually to the target if Sonar on the attacking submarine has a good Sonar Bearing and Target Solution. Once a Torpedo is shot however, it is much more difficult to hear anything else, as the noise produced by the Torpedo engine and screws pretty much drowns out everything. It's like putting your head underwater next to an outboard motor propeller that's running at full speed.

Towed sonar arrays are not used for such detection - while the information is classified about what they ARE used for, and how they're employed, they're essentially useless for torpedoes.

There are few things I remember from my Submarine Sonar days (see my bio) more chilling than the sound of a torpedo tube door opening, or the sound of a torpedo in the water aimed at us (exercise shots of course). I remember one particular operation in which I was in the Control Room rather than my normal station in Sonar on the main stack during Battle Stations, and as the exercise shot passed under us you could hear its active sonar pinging the hell out of us. I remember the CO saying "That could be the last sound you ever hear".

The sound of the high-speed screws of a Torpedo in the water is absolutely unmistakable - it sounds like an electric shaver underwater. Though all Sonarmen are trained to know what torpedoes sound like, in modern submarine warfare, it's the boat that hears its enemy first that has the tactical advantage. This is why sonar systems with long detection ranges have been continuously developed.

It's important to note here the Rules of Engagement for engaging/shooting a torpedo at another submarine or ship, and it was demonstrated in the movie "Hunt for Red October". No submarine commander may shoot at another unless the other boat has shot a weapon first - hearing a tube door open wasn't enough. These rules were followed by Soviet and NATO submarine commanders, and was in large part a huge reason there were no attacks between boats, no matter how adversarial. The plain fact of personal responsibility was key - no skipper wanted to be the one to start a war.

Of course that didn't mean that if the other guy wanted to try, we wouldn't evade his weapon and sink him either.

Submarines are designed with enough ballast and control systems to allow them to submerge and surface as needed.

Surface ships are designed only with enough ballast and control systems to keep them on the surface. While they can sink just as well as submarines can, their ability to re-surface without a salvage operation is non-existent.

At the beginning of 1917 the German navy had 111 submarines. This was a large increase from 1916 when they had only 68.

Technically a Japanese Suicide sub could collide and explode into an American or other Allied sub, the resulting blast effects dooming both vessels- however, there is no evidence this actually happened during the Pacific war, the only two confirmed Kaiten (one-man suicide sub) kills were of a large tanker- and a destroyer escort- both surface vessels- though Chan:s motto applies to a ( sea-fight) more than other types of warfare, ah so the Motto of the Wise is- beware of surprises. Jap Suicide subs had an attack speed of 45 KNots submerged!

No of course not
