Try the Fast 90 method of attack. Much simpler, works great. Only have to determine course and speed of the target.

There is actually NO difference between the Fast 90 method and the video linked in message #4. It is just that in the video the lead angle is computed graphically. 0.9 km along the course roughly perpendicular to a 3km length of the torpedo path, makes a 16 degree lead angle on his map. (should be 17.4 according to the numbers) The fact that the uboat wasn't completely perpendicular shows that you can still pretty much aim and hit where you intend it as long as speed is reasonably correct.

Sure thing. Need any help, just ask.

I.e., I don't worry about torpedo speed nor that target speed radius and assoc. lines he drew. Only line on my map is the target course.

a) Real u-boat captains would put themselves on the same course as the target from a long distance, then test different speeds until the target remains on a constant bearing while not getting any closer. Using your ship's speed, there you go: you got her speed. b) If the target is within 3,000 meters range and you see a good length of her side (so between 45-90 degrees AOB), bring you boat to Ahead Stop. Ideally, you want your bow in her direction or close to her direction. When your speed reaches 0 knots, put your periscope's sights in front of the target and do not move it. As soon as the target bow crosses the sights, start your stopwatch. Stop it only when the end tip of her stern crosses the sights. Using the ship's length in the identification log, make the following calculation : (1.875 X Ship length in meters) / Time on stopwatch in seconds = ship speed. c) If you use map contacts : Make a first mark on the ship's position on the map, then start your stopwatch. 3 minutes and 15 seconds later, make a second mark on the ship's updated position and stop the watch. Measure the distance and divide by 100, and you have her speed in knots. Last edited by Drakken; 05-08-20 at 02:06 PM. |

When submerged, I always use the tools on the top right note pad, i.e., target distance, target bearing, target speed and usually, launch my torpedo when the shooting angle shows 0°.
When surfaced, I let my XO do the shooting ;-)
