Okay I have been trying to sink the cruiser in sub school #3 using 90 degree approach and I keep missing ahead.


I use 12 kts as target speed, send it to the TDC, max out the range, select 10 degree lead angle, set the Aob to 080 (090 minus 10 deg lead angle). I open all doors and set speed to high.

My course is 000 and as the target crosses 350, I shoot EVERYTHING as the target passes from its bow to its stern. As I check the attack map, all of the torpedoes miss ahead.

What did I do wrong? Should I have shot as the target crossed 000 on the periscope instead of 350 or leave the Aob at 090?

Any suggestions? I was using O'Kane attack crib notes as reference.

Thanks

Have you put the periscope to 350 and then pushed the "send to TDC" button?

( I'm just a noob but I'm practicing the same thing )

Yes, I set the periscope to 350 and sent the info to the tdc.

You didn't mention it but I assume the target is heading 090. Right?

Yes, the target is heading 090, in the begining anyways.... I did not check its course again, since I was rushing through the calculations before it had past. MAybe I need to re-check its course....

I take it you guys are practicing the tutorials by Rockin Robbins, the O'Kane 90 attack, ect..

You'll have it down soon enough if you watch his video's. He even has cards you can print out explaining each method until you get it down.

Jep, that's the one! Very nice tutorial! Got the cards printed out as well.

Yesterday almost got it right but stupid merchant suddenly felt the need to change it's course...

That is, because the cruiser runs at about 9 Knots, if i recall correctly. The O'Kane Method cancels out range, not speed. So getting the correct speed of the target is important.

Try to hit the Mogami with AOB set to 80, lead Angle 10 deg (Periscope at 350 deg.), and torps to "fast."

Open the outer doors well before firing and fire when the part that you want to hit crosses the hairline at 350 deg. in your Periscope.

The O'Kane Method is, at least for me, by far the easiest and the most successful.

Keep trying. It takes a bit of time. Took some for all of us to figure things out. But its quite rewarding when in the end, you sink ships the manual way.

MAGIC452's reply included the following;
"With map contacts ON and if you have entered good data, looking at the attack map there will be a white X that will be right on or very close to the target and it will follow the target as it moves. If the X is off adjust your data till it's correct. As long as the X is on the target you can fire and should get a hit."

How do know how to adjust your data for the firing solution by the relationship of the "x" to the target? If "x" is behind does that mean the speed setting is off? Which way, too fast or too slow? Is the AoB off? Which way, too sharp or to shallow?

If the X is closer to your sub than the target, the range is short. If it's farther than the target, the range is long. The target and the X both have a line indicating the heading. If you get the AOB correct, they'll be pointing the same way (if you're really good, the X and heading will be right over the target). For speed, observe the X and the target. Remember where they are, relative to each other. Take another look after a few seconds. If the X is moving ahead, your speed estimate is too fast. If the X is falling behind the target, speed is to low.

If the X is nowhere near the target, moving in the wrong direction, you're using my method. It doesn't work too well.

Default my two cents worth

Since I have not been able to play because my gaming computer died [permanently], I have been scouring the forums. Here are my two cents on manual targeting.

Hitman's tutorial on Manual Targeting at 100 percent Realism is a great way to be introduced to manual targeting. It teaches the concept of aspect ratio which is REALLY important. It forces you to do the math, so the concept sinks in.

Also, gutted's [what a handle!] Solution Solver program, along with his tutorials, will aid in understanding as to how aspect ratio and Aob change as your boat and the target change position. Finally, the easy Aob mod is indispensible, as it enables accuracy at long range. All of these will make understanding lead angles, etc. and the O'Kane Method much easier in the log run. (I wouldn't listen to anything Rockin Robbins says... he taught me everything I know and introduced me to manual targeting.)

Learn to read the dials on the PK and the Attack Dials. Use them to verify your set up and use the Attack Screen to ensure your torpedo angle will get you close. Remember, early war torpedoes often run deep and that ducimus' destoryers in TMO are programmed to keep you very, very honest (Is it an accident that my motherboard died at the exact moment my boat was sunk by a TMO destroyer depth charge? I don't think so?)
