Lordy, I didn't know that..They'd rather duke it out with a ton of Amatol or Torpex or whatever the hell they use? But then, I suppose it's the rational alternative..You don't want a great fat torpedo running it through like a virgin on prom-night half a mile underwater, do you?
Reminds me of explosive reactive armour used on some main battle-tanks. On being hit, a flat plate of armour with a layer of plastic explosive behind it (not unlike a claymore in principal) detonates on impact with a HEAT round, deflecting the blast (in theory.)
I like armour, interesting stuff.
The only use for armour now is to protect against heavy guns (which are a thing of the past now) and bombs dropped by aircraft.
I found this message-board entry. With a tiny bit of searching you could find out plenty about it, it's no secret.. http://boards.straightdope.com/sdmb/archive/index.php/t-256970.html
Doesn't aluminum seem like a bad idea for the hull?
interesting fact, did you know that submarines can travel faster underwater then above?
No, it is brilliant due to its weight/strength ratio.
Not the strength, but the radar visibility.
Best guess is MAD. Then the sonar equivolant of the ESM mast.
I can't think of any other passive sensors off the top of my head.
Ah, passive acoustic, and non-acoustic. I didn't say the non-acoustic was passive,....
I'm guessing by acoustic you mean sonar right?
I can't imagine a submarine using a MAD system.
Although I do think it would be prudent to outfit a tomahawk cruise missile with a MAD sensor and program it to fly around where you think the enemy sub is.
Side scan RADAR and satellite imagery. Correlate data from devices in the water with those above.
Ask yourself, does the submerged bow wave from a submarine travelling a few hundred metres below the surface leave a detectable impression on the surface, or make a significant difference to the shape of the waves where it meets the surface,....

Not really no.
Most submarines can't even communicate while submerged below 20 meters without a buoy.
Even then its only a one way transmission from the surface to the submarine.
Er dude?
Phlo, water isn't exactly the best environment to transmit radio messages in.
