If so, since calculation of a target's speed is in part a function of its range and and time (i.e. the number of seconds it takes the target to travel its length), a delay in setting the Aob after speed is calculated may result in an inaccurate determination of Aob. This might result in screwing up the firing solution.
If the foregoing is correct, then as a general rule it seems that speed should be calculated after range and Aob are calculated. If a target takes a long time to cross a bearing on the periscope, or if is travelling at a high rate of speed, a subsequent Aob determination could very well be inaccurate. In the KIUB written tutorial, Karamazovnew's calcualtes range, Aob and speed in that order.
One altermative is that you can calcuate speed first. Then recalculate range and Aob. This means that you will make a second range reading to caluclate the target's speed.
Is may analysis of this issue correct. The above assumes that the KIUB interface is being used for the range, speed and Aob calculations.

Correct, within all the parameters course is the most stable, as long as your concealment is proper. The AOB can be determined by eye, by the KiUB, or from your map tracking data. The speed in OM can be tricky, these targets like to change speed so its important to listen to the officers calling speed changes from the hydrophone or from the scope when up. Its always a good idea to do a guick check of your data about a minute before firing to make sure the solution is viable. Then you get close 800m or less which assures that any minor error is irrelevant.
Happy hunting!
