I am trying to establish the distance L between the attack periscope and the bow tube muzzles.

I set up P at Bp = 270* at 3000m

Totally eyeballing the terminal run back to the 0* bearing line to somewhere near 140 meters from the center of the submarine icon.

Assuming the game uses the correct values for reach and advance, I backtrack the distance L to be in the area of 33.5 m +- 2 meters uncertainty.

I will use 33.5 as my initial guess and look at the consequences, to try to narrow it down to a closer to exact value.

If 33.5 is correct, then L + R is constant and equal to 43m.

Then the side S of the triangle that is on the 0* bearing is

S = 43 + 95 * tan (0.5 * g)
