What happens when...
 

Lightning strikes a U-Boat?

Reading a book by Edward Young who was the first RNVR Officer to join the RN Submarine branch. In it he describes a passage across the Med as the watch officer. All of a sudden an electrical storm started and a fork of lightning hit the sea a bit too close for comfort. He made the decision to dive because he didn't know what the result of a lightning strike on 700 tons of steel surrounded by water would be.

Any ideas?

Mmmhhh... interesting topic.- Maybe it could just happen like in a car, a Faraday effect where the electrons go around all the trip on the metal not damaging the people inside it... but, I don't know the "neutral" parts of a sub's interior and how could it be isolated from the current... (in a car, for example, we have plastic pieces and a metal chassis)

We must remember, children, a U-boat carries EXPLOSIVES on board. You might find that the entire thing would blow up.

Well, maybe you are right my little boy... but not all the explosives would explode when they are hit by a current... even the WWII explosives... I don't know the exact composition of a T2 explosive head, but maybe the Faraday effect would protect them from an explosion, just by discharging the current away.-

Perhaps...:hmm:

And I'm 47, not a child.

So why are you playing at being a u-boat commander? At least I have an excuse...I'm only 33 :)

Je, je... I'm 27 here... And perhaps, maybe you just get lucky and it doesn't explote... Sincerely, I don't know if the T2 would explode or not with the current from a lightning. Maybe some research would help... but I think it's a good question... Ahoy, Kaleun!!!

Apologies for jumping in with an unrelated topic. Stealth_Hunter? Could you confirm you got my PM ref. the sig image? Got to drop offline shortly. Thx.

Don't forget, it isn't just the explosives themselves, but the pistols (ie., fuzes). They tend to use much more sensitive explosives to set off the less sensitive (but more powerful) main charge.

You've also got AA and deck gun ammunition to worry about, especially those in 'ready' containers outside the hull.

Then too, you have things that don't react well to overcurrents and overvoltages, like batteries, motors, and various electrical circuits.

All these scary things on board? Maybe I ought to request a transfer to the Red Cross.:o

Doubt they would have you
You have provided quite a few of their " customers "
:rotfl:

You have no excuse, you damn Irishman.:rotfl:

Anyway, it never hurts to use a little bit of imagination for some immersion... just as long as you don't go too far, or you risk going Gothic.

Ekhem wouldn't it be the same case with everything that floats and is made from steel? ;)

Once we were diving in a small flooded excavation. But with heavy overcast from all the sudden and lightnings we felt we should get the ... out of there ASAP ;) But still I don't know how it would effect us and probably don't want to try this on my skin ;)

Well my grasp of physics is on a par with my grasp of computers, I know the stuff works but I'm buggered if I know how.

In cars its the tyres that prevent the charge earthing isn't it?

But what happens the unlucky kaleun who sticks up his scope, grips the handles and gets a lightning strike? Whilst standing in his steel tube surrounded by extremely conductive salt water!!

I assume the GWX team haven't factored this scenario in :p

I am not sure, whether the Faraday-effect would protect crew & boat entirely.
Maybe the ocean-water conducts lightning better than a metal Uboat? If so, then lightning would find an easier channel straight towards the ocean-surface, then to a Uboat.

But I do know, that lightning is a pretty rare event out on the open oceans.
