@liefsillion2825

Good question! Sea water is an electrical conductor. And the ocean is very well grounded so it is hard to see how a potential difference large enough to produce the current required to fry the wires could be generated underwater. This suggests that an EMP would have little affect on a submerged submarine. Not only that, a submarine is a tube made of steel ... which, in effect, is a large Faraday cage which is also well grounded. This suggests that even a surfaced submarine would be partially protected. However, microelectronics is more sensitive and a transient voltage spike of any kind could reasonably be expected to corrupt the contents of volatile memory requiring a reboot and data restoration of digital computer systems ... which would take time. Externally mounted sensors might not survive. In general, the intensity of an electromagnetic field varies inversely with the square of the distance ... meaning that distance is your best friend. The most likely scenario might be a low yield nuclear warhead delivered on a torpedo or depth charge, detonated in proximity to a boomer in a desperate attempt to take it out before it can launch any more SLBMs (i.e. other than than the ones that have revealed the boomer's location). Of greater concern, the shock wave, propagating through water, would probably be sufficient crush the hull. An EMP weapon detonated at high altitude would probably have little or no effect. Any comments?

@@vincitveritas3872 Yeah! Not a pleasant way to die. Submarine rescue vessels are few and far between. They typically take days to get to the search area and then they have to find the downed submarine. They would probably send a robot down to evaluate the condition of the boat and of the emergency exit hatch seal before they send down a submersible to attempt a rescue. This takes time and it is only possible in relatively shallow water. Most of the ocean is very deep and the pressure increases rapidly as you go down. If the submarine propulsion and buoyancy control systems have been damaged there is not much hope if it coming up again. As it sinks, the hull with start to make freaky noises as the submarine goes below its crush depth. Even the strongest hulls made high strength steel, or even titanium, will fail below around 1000 m (the exact details are kept secret but the physics calculations are straight forward). So, the end game is that the hull will implode under the pressure in a massive boom that will be detected hundreds, if not thousands, of km away. This would happen suddenly but the waiting around for it to happen would be truly terrifying! Nuclear torpedoes and depth charges are diabolical weapons. They don't have to get that close to a submarine to take it out because they use a shock wave to rupture the hull. And, they don't need to be high yield because the shock waves they generate are easily propagated in water. There is not just a single shock wave. The detonation will generate a fireball which will vaporise thousands, if not even millions, of tons of seawater. This steam ball will expand and cool until the pressure falls below that of the surrounding seawater. Then, it will collapse again, superheating the steam and increasing the pressure up to a point where it stops, and then starts expanding again. This rapid cyclic process will repeat as the steam ball rises in the water column until it reaches the surface. So, there will be a series of shock waves of diminishing intensity over time. On the bright side, they can't kill you if they can't find you! Submarines depend on stealth to stay out of trouble and hiding under an ice sheet makes them very hard to find because they are concealed from satellites. A nuclear submarine can stay there for weeks, if not months. This is why boomers are the premier MAD capability. Bombers can be shot down and ICBM silos can be excavated, but boomers are so hard to find that you won't get all of them, and just one of them can cause unimaginable destruction. So, if you start a nuclear war then you will not survive. MAD is a mad idea but so far it has worked. The key is you have to convince the other guy that you are mad enough to use them! This is what Putin is doing at the moment. He is following the standard playbook. Paradoxically, nuclear sabre rattling actually reduces the likelihood of a nuclear exchange. The US runs attack submarine patrols in the vicinity of adversary boomer bases. When they head out to the open ocean they follow them, hiding in their baffles where they can't be heard, and follow them around. They can detect the sound of a boomer opening its missiles hatches and in wartime this means they attack before the can boomer can launch its weapons. Advanced torpedoes have a re-attack capability so if they miss the first time around then turn round they come back! This will delay the missile launch because the boomer will have to evade the attack or risk being destroyed. A boomer might have an escort though whose job it is to intercept an adversary attack submarine before it gets close enough to attack the boomer. Being a submariner is a dangerous profession in peace time. In wartime it becomes extremely dangerous and especially for a boomer because the prosecution would be intense. It is not a job that I would want to do!

Think China is a nuclear threat? China refuses to decrease its number of nukes (300), despite polite requests by the USA and Russia.

@@shelleybeyar570 Really? I wouldn't believe everything you see on KZread! A diesel electric submarine running on electric motors and moving at low speed can be very quiet, but a nuclear submarine ... nah! The cooling system of the nuclear reactor and the low frequency rumbling of the rotating steam turbines generate a lot of noise especially if it is moving at high speed which is required to transit long distances to and from their bases and their patrol zones or if they are obliged to evade an attack. They can hide under the thermal boundary layer in the ocean, if there is one, but variable depth sonar mounted on surface vessels and ASW helicopters can find then down there. Sure, sound isolation techniques dampen mechanical noise but they only contribute to lowering the overall acoustic signature of a submarine. You also have the problem of the propellor. If it spins too fast, the water at the tips will boil and form bubbles of steam. This is called cavitation. As the bubbles cool down they collapse and go pop! Lots of bubbles ... lots of noise! High rotational speed ... lots of bubbles. And sound travels a long way underwater. It travels lot further than it does in air. The only ways to prevent cavitation, for a given propellor, are to either slow down or dive deeper to where the pressure is greater. A submarine can be very difficult to detect if it is sitting stationary on the seabed. They can also be very difficult to detect if they are sitting stationary under an ice sheet. In these cases the irregular surface of the seabed or the ice creates lots of sonar echoes that allow the submarine to hide in the background noise. But a stationary submarine is not much of a threat. Sooner or later it will have to move in order to carry out its mission and when does, it will generate hydrodynamic noise caused by turbulence as water moves over the hull. The bigger the submarine the more noise. The faster it moves the more noise. There is not much you can do about basic physics! As yet, nobody had been able to develop the mathematical calculus required to accurately model turbulence using computers but when someone does they will receive a Nobel prize. The increasing level of background noise in the world's oceans caused by increased volumes of maritime shipping and increasing populations of whales is making it harder to detect submarines. However, modern integrated ASW tactics involve the use of rapidly deployable multi-static sensor networks in open waters and seabed sensors at critical undersea choke points which can make life very difficult for submarines. Typically, these passive sensors use triangulation to determine the general location and then call up long-range airborne assets to hunt them down. Submerged submarines have difficulty detecting aircraft and can't hear them coming. Typically, the first indication they have of their detection is "torpedo in the water"! And then they are obliged to go to flank speed in an attempt to deplete the remaining energy in the torpedo before it can reach the submarine whilst simultaneously rapidly changing depth and deploying decoys and noise makers to distract them. So, there is a bit more to it that simply placing rotating machinery on platforms that that are attached to the hull using springs and rubber blocks. Anything as large as a submarine is going to make a lot of noise when it moves through the water especially at high speed. For some more information about the analysis of acoustic signatures have a read at www.naval-technology.com/analysis/understanding-acoustic-signatures/ Or have a look at kzread.info/dash/bejne/iYZ4qLOKe9rHg8Y.html to see how submarine prosecution is done these days. This video is a promo to sell aircraft, so it makes it look easy, and as such it is propaganda. It is not that easy in real life, of course, but it gives you the general idea.

After all that talk these subs are absolutely absoleet Waste of time money and life we are hunted by our own feer and that's what is going to distroy man kind

Nice job of spelling. Did you ever graduate Elementary school ??

Business as usual, making and spending money, submarines included. There is no end to human foolishness, love playing with matches and not burning their fingers, it happens now and then, then the curtains burn, then the furnitures and finally the house itself, business as usual, kills boredom apparently till death put an end to this madness.

Does't matter how good you are, Cockiness will be your undoing. Personally, I wouldn't Launch a Nuclear Attack if given the Order. I would probably surface with a white Flag . . . .

Especially now with xiden in office and his corrupt regime. It just gets worse and worse as time goes on. More and more corrupt, out of control, and out of touch with everyday Americans.
