View Full Version : Did they do that??

Ok, my grandfather told me that at some point during World War 1, the british experimented with an anti- torpedo device. The point was, if there is a torpedo heading for the ship, very close to the surface (and i mean very), they would turn on this huge leaf-blower like thing to blow on a torpedo and hopefully blow it off-course. Now, my grandpa passed away a couple years ago, so i can't ask him again... did anyone else hear about that, and if so, how effective was it? (i suppose not really)

It sounds surprising that they tried something like that at all.

I'd doubt a fan would have a significant effect on a heavy torpedo going toward a ship at up to 44 knts.

I can imagine all the men on the deck blowing towards the torpedo, adding just that extra little bit of wind to blow the torpedo off course.

I wouldn't be suprised if they didn't try something like that. I would imagine, at a time of war, they would get desperate enough to try anything.

I haven't heard of that one, but I remember hearing of many unusual tactics used against submarines in an attempt to stop them, even to the point of ment throwing pipes with charges on them into the water hoping to hit a sub as they passed over hwere they thought it was.

Thing is, by the time the torp got close enough to be effected by the wind, wouldn't it be much much too late?

I never heard of that (which does not mean it's not true) but it could be possible. The Pommies tried some weird things for AS warfare.
I remember reading (don't know where) that the pirst AS patrols in Scapa Flow during WWI were nothing more than very small boats, armed with a sack and a hammer. The sack was to be pulled over a periscope and the hammer should be used to smash the lens. Crude but effective. It does make a submerged sub blind. http://forums.ubi.com/images/smilies/35.gif
Provided you see a periscope and manage to get within touching distance unnoticed. http://forums.ubi.com/images/smilies/88.gif

How would that be possible? Torpedoes had been gyro-stabilized for a long time. Perhaps they could blow the torpedo downwards.. I don't think they were sophisticated enough to stay at a set depth.

Lots of wierd things where tried in WW1, even in WW2 against submarines/U-boats. Even wierder things in WW2 against aircraft so I'm not surprised if something along those lines where tried.

Basically in WW1 uboats where more dangerous to themselves then the enemy was to them. Depth charges weren't invented until after the war, hydrophones where in their infancy, ASDIC hadn't even been thought of.

The only really effective weapon the British had against Uboats in WW1 was Q-ships. The Americans used their submarines to escort convoys, the tactic being to hide amongst the merchants and then when a uboat surfaced to stop and then sink ships the submarine would submerge and try to sink it with a torpedo. No successfull hits where ever recorded in history of the time, though there are german records that indicate many near misses did alot to reduce crew morale.

I think your gradnad was pulling your leg. I often tell my young nephews "strange facts" like clouds and aircraft stay up in the air using sky hooks. After all clouds are just water, so how do they stay up? Well when it rains, its because some of the sky hooks have broken and the water is leaking out, so they move the cloud to somewhere else so it will stop raining. But because the sky hooks are so old and worn, they can never move enough clouds to places where water is needed as they always break before they get there. And as everyone knows Santa makes clouds at the north pole, but he is running out of ice now.

Ships did have booms with torpedo nets attached. so that if the ship was stopped they could swing out the booms and drop the nets, which of course would stop a torpedo.


There was even device made to travel underwater with a periscope sticking out of it. It would dispense fish and ofal to seagulls so that they would associate persiscopes and food, and flock to any enemy submarine, hence giving away its position. This is modelled in SHIII as if you enter an enemy port submerged, the seagulls will flock to where your boat is. If you don't believe me try it!

You sure that depth charges weren't invented til after WWI?

This page says otherwise ^

It lists the year of design and service of Type D Mark III as 1916 and TBH I've never seen a source say that DCs weren't used in WWI.

Hmm I'm guessing they where a really late war invention it looks like. Odd I'd always read that escorts weren't outfitted with Depth Charges until after the war. Though by that very source.

"In mid-1916 the D-type depth-charge had been developed, but there were reliability problems with the firing pistols. Production of these much needed weapons was hampered by technical difficulties, resulting in strict rationing of their use by 1917. Usually, escorts carried no more than 35 DC, which, given the unreliable detection methods of the time, was considered to be quite inadequate. The Allies sank about 30 German submarines with DC in World War I."

Does indicate that it was very unreliable and in short supply. So in essense my statement is true until 1917. Considering the war ended in 1918 they weren't a huge impact. Though I'm sure the crews of those first few Uboats attacked with them were wondering what the hell was going on.

Question is... how many brave souls were lost during the trials before the idea was scrapped?

A majority!

I imagine that a fan powerfull enough to change the direction of an incoming torpedo would be powerfull enough to move the ship using it out of the torpedoes path...
