- "E-Meßtafel" - upper part .. what is it telling us?
- "E-Meßtafel" - lower part .. what is it telling us?
- "Lead angel tables" - what for and how to use this one?

These tables are from the real Marine-Dienstvorschrift 416, “Torpedo Firing Regulations for U-boats”, and the ones in question are as follows:

Lateral distances in hectometer:
When the target is at a given range and AOB, you are X number of meters off its track. In other words, if you were to stop moving, the target would pass you at that distance. Handy for monitoring your approach.


Speeds for the approach:
The AOB figures given at far left in the table are the intended AOB at the shot. The AOBs from 10 to 50 next to that are the current AOB. To use the table, as you approach underwater, set a perpendicular course, figure out what the current AOB is, and target speed (ideally you have gotten both by matching prior to submerging), and then figure out what the AOB is that you intend to shoot at. The table will then show you the approach speed to set to achieve a collision course. As you get closer to the target, bump the speed down, because you don’t want to collide, but want the target to pass say max 1000 m in front of you for an ideal shot.

E-Meßtafel:
The top part shows the distance to a broadside target of x length when it fills your optics laterally. If not at a perfect 90° AOB, you need to take that into account. This is not for precision range work, but simply situational awareness. The lower left-hand part shows a rendition of a scope, with a ship approaching. It’s intended to show you the number of minutes you have until that ship arrives at your location based on its range, and speed. The lower right portion is time, speed and distance at the different telegraph settings.

Lead angle tables:
If intending to do a shot without the use of the TDC, you simply pick the angle on bow you would like to shoot at, cross reference with the target speed, and that tells you the lead angle for a zero Gyro shot. Make sure you’re using the correct table corresponding to the torpedo speed. Maneuver your boat on an approach course that makes this happen, setting the periscope to the lead angle, making sure that Gyro angle on the TDC shows zero, and firing when the target crosses the wire.
