Ouch !

Ever heard of this ???

Rockin Robbins · 06-02-10, 11:24 AM

Never! What a cheap device, and it looks like it could be hazardous to a submarine (oops! U-Boats are not submarines) I mean U-Boat's life.

Never heard of that before, wonder if it actually worked? wonder how they got it attached?

Rockin Robbins · 06-02-10, 01:31 PM

It says they were dropped overboard in large quantities when over a lurking U-Boat.

Wonder if they created so they could hear the gunshots of the crew shooting Bernard for the clanking. Hey, it would be the only logical explanation of a stray sound you could detect in the boat; it's Bernard. Shoot him and it might go away.

Sorry about my cynicism, but that thing looks pretty useless. Why would you drop a swarm of these things on a submarine's (U-Boat's) exact position if you can detect them already? The ambient noise of the machinery within the sub would probably make more noise. It's not very descriptive in this video either. Dose it have a little motor and battery in it? Or does it rely on the current of the water moving around the hull. I think it was one of those things that were tried and failed.

Funny idea though...

Why currents and floating around ? If it got attached it would just stick to the sub and make constant noises, no motor or anything needed for that. Just the constant movements of the water, especially when the submarine is moving too, which it would be when submerged to keep depth.

Also, if you got a contact with the sub once it doesn't mean that you can keep it or easily get it again after losing it. If a submarine can sneak away because it turns its narrow side towards you (the DD) than you might not be successful with ASDIC while you also can't hear it.
I think submarines could be *very* quiet if they had to. But this thing made a sound like hitting with a wrench on a steel bar attached to the hull inside the submarine. I don't know how loud this is compared to the usual ambient sound of crew and boat but nobody would have dared to make sounds that loud while submerged and being persued by a DD.

The only thing that makes me wonder is how exactly these things where supposed to get stuck on the submarine. Magnetism ? Glue ? Suction Pads ? Anything even more ridiculous ?

It looks like magnetism from this short video. If I had to guess. But with a slippery rusty barnacle encrusted hull even that wouldn't work with a little thing like that.

I'm thinking it's, like I said, it either didn't work or is a bs thing. I did a search and found no other reference to it on google.

It was probably an idea like training seagulls to follow a periscope.

Now THIS was ingenious!

Yeah, something must have been wrong or otherwise it would have been used for real. _Or_ somebody was just stubborn and thought it was too hilarious to actually use it

These things were brutal, instant kills if they could hit :/

For underwater warfare in ww1 and 2, we could have learned more about sonic effects.

Cool it's like a modern ww2 hedgehog.

Bad for us subbies!

Especially me in sh4, a harbor raider!
