I don't think any were launched at a depth lower than that...

EDIT: There was a story I heard a while ago about a british sub I belive torpedoing a german sub while neither were at parascope depth.  The german sub had been damged by either an alied ship or plane (pretty sure it was a ship) it's engine was making a loud clunking sound and the british sub heard this on their hydrophones.  They did some brainiac calculations and came up with an approximate range.  They fired 4 torpedoes at the german sub but only the last one hit.  It was the only non-parascope sub kill (I belive the only sub to sub kill), and the last german U-boat sunk during the war.

could you imagine looking through the periscope drunk and not realizing you're looking in the wrong direction when you give the order to fire torpedo?  :rofl  :lol

    Anyone know what the maximum depth for launching a WW2 torp is?  I know they usually launched at periscope
depth for obvious reasons.

Torpedoes now are even launched at a relatively shallow depth. It's a matter of the amount of air pressure needed to launch the fish out of the tube at depth due to the water pressure.

Launching a torpedo at 200 feet or lower, while possible, would use much of a submarine's reserve air to do so as I understand it.

In regarts to WW2, torpedoes travelled in a straight line for the most part. No homing. I believe they could be programmed to make predetermined turns but were otherwise line of sight.

yes, they needed compressed air to shot the torpedoes.
and i think they (the germans) experimented with magnetic torpedoes at some point, but didnt bother with them much, as they kept coming back to hit their own ships? correct me if im wrong.

The Germans had passive Acoustic torpedos that followed noise. They had magnetic warheads that allowed torpedos to get below the hull of the ship then explodes breaking the back of the ship causing much more damage then a direct impact.

As for sinking the Subs I only have one thing to say....  :noid PBY-5A with depth charges!  :noid

Sucks if a whale got in the way, not only did you not hit your target, the enemy now knows where you are at.  :noid

That wasn't what I was thinking, I am just having a brain fart and can't remember the name of the ship you use to sink a sub.  But I like the idea  :aok

No, but water is.  Mythbusters proved that and the sub would only need to dive about 10 feet under to be safe from all rounds.

Don't believe everything you see on Mythbusters. not all their information is correct. Such as their theory that you can shot and arrow from a bow and then shoot another arrow and have it take the nock off and go into the first arrow. That happens alot, more times than you could imagine.

as to the water being "bulletproof" it depends on the angle and the size/speed of the round in question as to how deep it would go.
.303s may not go that deep but 20mms probably will.

20mm are cannon rounds and would explode on impact to the water.

Actually, that episode was fascinating to me because I was expecting the higher-velocity rounds to do better.  The .50 BMGs died out practically as fast as the other rifle rounds, which shocked me.  I figured a 700+ grain FMJ would go through more water.  Like demonfox says, cannon would explode on impact.

destroyer for one...


water is not "bullet proof"...for that to happen there would have to be zero penetration. don't forget a 250lbs bomb can get deep enough to put a nice hole in your sub...especially if it has a delayed fuse.

actually the ships that hunted u boats were called Corvettes
