target speed: the eighty-ten method

Do we run ahead at speed until we get a 10 AOB, then start the approach?


It looks to me like this attack method will only work in a very limited set of circumstances.

That's still what doesn't make sense to me. Watched the youtubes and basically it's set up.

Say I'm going north and I get a sonar contact at bearing 170. Say it's a group of merchants, but running in a row at 12kts. I can't see it, so do you hit the gas until you have it in the correct position coming towards you. If contacts are off and if this works it would only be a tool for contacts off, you would have to track it by other methods until it's on a perfect path, but by then I would already have my setup.

It just doesn't make sense unless it's one ship and all factors are perfect.


The bigger problem is I'm not going through all this when they're much easier ways for a single ship. I still see no way it could work with a large convoy or TF with ships in a zig pattern with escorts constantly making zigs. Your sonarman will tune into different ships, giving different commands.

The real tool is radar, not the blind use of sonar. This appears to be using your elbow to scratch your arsehole.
