Ever pulled a Capt. Dodge?
 
I was just wondering if all of you experienced Kaulens ever pulled a Capt. Dodge (Down Periscope) and pulled in underneath a huge slow moving tanker to avoid detection?? And would this help avoid detection?? seeing as how some one listening would hear the tankers screws and ASDIC would probably also pick you up as part of the keel of the tanker?? And if anyone has done it Id like to know how you did it. Especially if it was with no external camera

Just a thought because I just read a post about some one sneaking into Gibraltor that way.

And while we're on this topic, what all interesting /wacky tactics have you all used before that have worked??

1) yes I have pulled one of those and the escort rammed the cargoship while trying to DC me. :DL

2) That's sonar not a hydrophone ASDIC would pisk you up but a hydrophone wouldn't. :up:

3) I sailed through two halfs of a sinking cargoship to stop a destroyer from catching me. :woot:

The escorts know you are under there and will circle the ship dropping depth charges trying to get you.:yep:

sat under a large tanker once after sneaking in to a convoy, but i was caught. it was going 6 knots so i was able to stay under, but not for long. destroyers were constantly zigzagging along side too. after about 10 minutes under it i let out a bunch of decoys and dove as far as i could.
i think theyd still be able to detect you, and no ships go slow enough that you can stay under them at silent speed.

Dang, I really wish Ubi would just release the SDK already so you all could have a crack into turning the game into something greater than it is, Id love that feature (because I do believe in real life sitting under a ship would make you impossible to detect or at least almost because of the 'sound' of their screws and such) and the ability to bottom out and sit silent not being detected among other things.

As it is now, (as far as I know) if you try to sneak in under a ship, the escorts will hear you and ignore the cargo ship. I don't think they even hear the ship up top :hmmm: But, sitting under a ship will give you cover from attacking escorts as they can't get depth charges on you.

Whenever I've tried hiding under a vessel in a convoy it always seems to be able to go faster then me :cry:

In real life it was theoretically possible, but you wouldn't be shielded from active sonar. Worse, they didn't have external view to confirm they were really right underneath, so it was a risky proposition at best.

But possible to do. :up: thats all Id need

*stops singing*
Periscope? slow cargo ship? dumb AI?
*continues singing johnny on the monorail* :arrgh!:

In real life you can't see very far underwater, and it's dark, and the periscope seals are not overly strong, so it's a bad idea to raise one at much deeper than periscope depth. Matching speed and course with a moving ship is difficult even on a good day.

Just make sure the ship you are under isn't that one you put a torpedo into 10 minutes ago...You might get a nasty surprise when it finally sinks :doh::doh::doh:

JokerOfFate 09-21-10 06:40 PM

If they don't know you're there, maybe it would be easier due to relaxed speeds.

What about 15m would that be too deep?


ralphnader23, you would be surprised to here the amount of times I've hit a sinking ship submerged. :dead:

It's technically, though not practically, possible. And so what? You can stay under the ship until it (and the escorts) despawn, but so what?

Of course, at just under keel you will need that sweet magic external cam. And why would you stay just under a keel? Why not 160 below it? At 160, you don't need to hide.

Fun, mate
To use what a friend of mine said
"Why does a dog lick its nuts"

(Not sure if I can say that but what the heck)

In real life, when Persicope was down.. I assume it has a door ontop of it, that closes?

Obviously in the game it just goes into a tube, but wide open to all the elements.

This technique was actually used by submarines of the Red Banner Soviet Fleet to evade Western ASW units during the Cold War but with very mixed results. In October 1962 the Project 641 (NATO codename Foxtrot) B-36 (Capt A. Dubivko) ran the Caicos Passage undetected in the wake of a 10,000 GRT tanker during the Cuban Missile Crisis.

It wasn't a popular manuever, some time before another Northern Fleet boat practicing coat-tailing a merchant had been sliced up by the freighter's prop and was almost lost.

See Peter Huchthausen's book, October Fury.

No door. The seals which keep water from getting into the periscope well can only stand so much pressure. And pressure builds up fast. Maybe they could use them a little deeper - I'm not sure. But periscopes that don't work well at night aren't going to work well as the depth makes the water darker.

I think the biggest question is, are there any accounts of subs using the periscopes at greater depths to track ships from underwater?

I once read where a sailor put on a mask and had a flashlight.. They put him into a torpedo tube and they opened the door. He used to look around for a bout 10 seconds then they would open the door again and let him in..

This tactic was very popular with this particular u-boat. They would do it all the time.. Then one time during a fight, they forgot to let him back in.. Thinking the torpedo tube was loaded because it triggered the load que, they fired him at a merchant.. The craziest thing... He ran straight hot and normal all the way to the merchant and banged on the hull with his flashlight for hours, till a hole began to form.. The merchant finally sunk 8 hours later with the entire crew (both sides) in total confusion..

:arrgh!:
