WOW! Thanks, don1reed, exactly what I was looking for. I've had subsims since the original DOS GATO, and always estimated distance to the track, but these type II U-boats don't have much to spare for last minute manuevering.
drEaPer, I'm brand new to this forum, but let me see if I can figure out how to post a picture; ![]() [/img] Target is red, subs are green, the track is the projected course of the target if he doesn't manuever. In all three cases the range to the target is 3000 meters, but the actual range is not what you want - you want the torpedo run distance. In an ideal situation you fire when you are at a right angle to the target within 500-1000 meters, and the gyro angle is zero. (Actual angle will be slightly less than 90 degrees, since the torpedo run is what needs to be 90 degrees) Sub #1 is 2000 meters from the track, he has to run like hell to reach the ideal firing position. Sub #2 is at 1000 meters from the track, all he has to do is wait for the target to get to the firing point. Sub #3 is way too close to the track, he needs to turn around and move away from the track to give the torpedo enough arming distance. Using don1reed's table it makes it easy to figure out ihow far you are from the ideal firing position, if the target range is 5000 meters when you first see it and the angle on the bow is 30, you're 2500 meters from the track and need to move 1500 meters closer. If the angle on the bow is 3 at the same range, you're too close to the track and need to move away from it. Especially when the ships are in convoy, it's important to do all the high speed running to get into position when the target is still as far away as possible, since high speed running near the target will give you away. |
