What is the warhead size on the torpedos in 1939, and does the size change throughout the war?

German torpedoes were 21 foot long, 21 inches in diameter and had a warhead of either 200Kg--440Lbs or 280Kg--615Lbs of Hexanite.>>TNT and Nitrate mix.

As I understand the warhead charge of these torps didnt realy alter throughout the war.

Torpedoes !...Big things....you bet !

****! Those are some big warheads. I was assuming they were in the range of 200-300 lbs.

what was the theory behind such a big size for the torpedoes? why did they have to be so big? it couldnt be for force in the impact,because it was the explosion that did the damage. Was it for holding the fuel? surely shorter torpedoes would have meant that more could have been brought on patrol?

Not theory Con20or but practical application:
The complicated array of internal mechanisms including but not limited to boilers (for steam power), gyros, guidance and rudder controls and their motors, depth regulators, compressed air tanks, controlling gears, batteries for various operations...etc..etc

ALL take up a lot of room LOL, its only about 20% of the torp (the warhead)that actually sinks the ship.

didnt know there was that much in them,explains why most of the major powers had torpedoe problems at one stage or another. How do they compare size-wise to modern day ones?

Im aware that im starting a "size" debate about torpedoes, but please, keep it clean. No "il show you mine if you show me yours" remarks.

Here is an illustration of how full a torpedo gets with its instruments.

A Type V Acoustic Torp from 1945 I beleive.

I'm not positive about this (maybe some of you current/former navy guys can fill in the real data), but I think most torpedoes these days have smaller warheads. Subs are almost exclusively used now to hunt other subs, and it just doesn't take that much explosive power to crack a pressure hull. Modern ASW torpedoes have computers built into them, much better hydrophones, active sonar, and I don't know what else.

Modern british hunter killer subs have wire guided torpedos (Steered to the enemy as a wire unravels which leads back to the sub) or acoustics.

Also warhead wise its about half the size since they dont need to blow up tankers and cargo ships, but then again they do have the dreaded "tactical nuke" warheads on torpedos also. So they dont even have to get a near hit http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

That and why get close enough to a surface ship to fire a torpedo these days when you can just fire and underwater launched harpoon missile or similar.

I've had the pleasure of being down a modern swedish Sub "v√¬§sterg√¬∂tland class "while being on guard duty with swedish territorial army.And the torps on that ship were not that much smaller.Don't know any data about them though the crew where quite secretive about them. Anyway torps are huge things.

Difference isn't that significant when you compare today's heavy torpedos to their WW2 counterparts, except for their capabilities and explosive power of coarse.

Weight: 1,814 kg
Warhead: 267 kg

Weight: 1850 kg
Warhead: 300 kg

RUS UGST

JUST AS BIG and they go further, and have more efficient explosives as warheads. If you look online you can probably find pics of Tigerfish hitting targets. Pretty impressive! Good example of breaking a ships back. (Old DD as target)

Tigerfish used in Falklands war against Argentine Ex-Brooklyn class cruiser General Belgrano (?)

According to a variety of sources the General Belgrano was sunk by Mark VIII torpedoes of WW2 vintage. http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif
