(ask) problem with enemy's course and precisely fire torpedo with sonar

[lajulanian]

I had a problem with enemy's course and precisely fire torpedo with sonar.

step that I already done :
1. I enter the sonar room, find the bearing until the light is on.
2. send bearing to the TDC.
3. determine the target. if enemy, in below 4000 m, it point to the some range.
4. I send the range to the TDC.
5. Fist : I set mark 1 to the enemy's ship.

and I repeat the sep 1 -5. until I get fifth mark. but the result on the mark is get me confuse.to set the angle of bow (AOB)

is there any suggstion ?

Nb: I use sonar because is Night. dark...

Thanks... sory for the bad english

Check out , should give you plenty of insight into how to do a sonar attack. If it doesn't load, is also very useful.

Full-sonar firing is, anyway, a secondary form of targeting and is usually less precise than visual methods... note that you mention precision, but sonar-oriented measurements always have a large margin of error. Can't you really peak for just a few seconds to add a stadimeter reading or two? That will increase your accuraty greatly.

take a peak ?? ok.. good advice.

thanks a lot..

I'm making another video of the Dick O'Kane Sonar Only technique some time soon. I borrowed a microphone last night and it sounded like a 1940's AM radio: not acceptable. Really there is nothing at all to be gained with a stadimeter reading. Sonar gives much more accurate (capitalize that. It's many times better.) range information than the stadimeter.

Where you might actually want to take a peak is right when you fire to get a perfect shoot bearing. On bearings, the periscope is more accurate than sonar.

So: your most accurate instrument for range is sonar or radar.

Your most accurate instrument for bearing is radar or periscope.

RR, that is understood, but you mean active sonar. By reading the fellow's procedure in the first post, I understood - incorrectly? - that he uses some sort of multi-reference calculation with passive sonar. I guess that if he was using multi-pinging, he would not have the problems mentioned.

There are also other things to consider, such as revealing your own position. I never - that of course is just my playing stile - use active sonar.

You must have some sort of visual, anyway, even if it just to identify the target. Wouldn't want a large liner on your conscience, would you?

That could be an interesting discussion. How frequent you captains actually use active sonar, and in which occasions?

What do you mean not acceptable? as least it would sound Period Correct!
