Skip to comments.Electromagnetic Pulse Question: Can an EMP be used to kill diesel submarines

Aside from the 20,000 artillery pieces North Korea has, an EMP attack by the US on North Korea would render the majority of North Korea's Defense capability useless: jet fighters, missiles with any sort of electronics, communications, etc.
But if a submarine is submerged, is it vulnerable to an EMP (Electromagnetic Pulse) and does water/depth the submarine is at limit the EMP weapon.
It is possible that an EMP attack on submarines might cause it to blow up as no telling what would happen. Plus the fact the submarine might have trouble surfacing.
Here is an interesting report on Global Security.org on EMP's:

If the US were to use an EMP attack, basically, the North could be crippled, but there would be loss of human life in hospitals (devices no longer working) or the loss of the Electric Grid.
North Korea has 72 submarines. I wonder if EMP devices (aka, bombs) could take these out and what impact being submerged has on the EMP blast.
I figure this is mostly fantasy. In Hawaii, simply a scheme to bring federal money to the state. Can anyone show anywhere a EMP gun or weapon or pulse has been tested or used? While it might, if used, bring a city to a halt, people with guns will not be slowed down, howitzers will still fire.
S Korea is far more advanced and dependent on electronics for their basic economy. An EMP attack by the US would likely hurt our ally S Korea more than our enemy N Korea.
The sub aspect is interesting but, I think, irrelevant.
A sub is a metal shell, like a Faraday cage, so I think it’d be unaffected.
Not if they’re submerged. Electromagnetic fields are greatly attenuated by water. This is why subs must either come to the surface to use radio or rely on VLF comms which penetrate the water but provide only very low bandwidth.
Google “EMP Report” to read more about the effects of EMP, don’t rely on 2nd hand sources. It’s all out there.
Plus you have a lot of conductive salt water surrounding it serving the same purpose. I would expect a submerged sub would be the safest place during an EMP attack.
They will mostly fire blind as there will be nothing but binoculars to find a target. Nork will be little effected as they already live in the dark ages.
A steel cage will block an emp. A submarine is pretty much that.
I’ve always questioned the effectiveness of EMP attacks. I think the damage would be very limited. Celluar service, radio communications, maybe. I don’t even see vehicles being affected much. Not saying it wouldn’t be bad, just not nearly the “doomsday” thing it has been hyped to be. Just my opinion.
It’s true that a metal shell will shield EM radiation, but any antenna will conduct the EM inside where it can fry delicate electronics.
I doubt that unless you send a little vessel to magnetically "latch onto" the hull. then detonate, you would NOT be able to disable a sub with an EMP. If submerged, you can't get it from above, I'm pretty sure.
You can bet that the Nork artillery has firing coorinates for every square foot of the south.
[EMP CAN’T STOP AMERICAN NUCLEAR RETALIATION]
The Diesel motors that run the propulsion system would not be affected by EMP, even if the sub were on the surface. But the sub, at depth, is powered by battery-driven electric propulsion, which if on the surface, WOULD be vulnerable to EMP, as there are all kinds of load-switching electronics, to shift between the charging of the batteries, and the draw-down of energy stored. Also, virtually all the guidance wiring and control surfaces would be knocked askew.
Could they cripple back to port? Maybe, but as a combat vessel, they would be virtually useless. And there might not be a serviceable port for them to repair to.
First a Toyota truck, http://www.freerepublic.com/focus/f-chat/3552960/posts?q=1&;page=1#1 Now a submarine? Two EMP threads in a couple of hours?!
The submarine hull is basically one big Faraday shield.
>>>North Korea has 72 submarines<<<
With no GDP to speak of, how in the world do they have the resources to maintain and operate a fleet of 72 Submarines?
Same goes for the thousands of Jet Fighters and of course their Missile and Nuclear Programs.
It’s a long-observed consequence of high altitude nuclear blasts, first noticed when Hawaii suffered extensive electrical disruption & damage from a burst about 1500 miles away.
I doubt EMP would have underwater effects.
anything enclosed in metal would be protected from EMP
If you have a metal shed, it would be a good place to store a spare generator, radio, etc.
Make sure it is ALL metal and grounded. (Floor too)
