1MC: 'Mathematicians to the bridge!'

Good evening Ladies and Gentlemen,

Been a long time since I started something like this, but I have this idea and I want to know how to pull it off.

Say I'm abeam starboard side of an incoming column of ships. And I want my eels to hit at bearing 000 (dead on) so, I guess the normal thing to do is to:
- achieve alignment (which is tad difficult if not impossible @ 100% realism)
-obtain column course
- obtain target speed and sync with firing AOB
- firing AOB
- torpedo range at set torpedo speed (which by the way, would be a mark 18)

I've tried use S/O/H , C/A/H,and T/O/A (trigonometry) to establish an angle but the speed thing is what I'm missing.

Bottom line, is there an equation or formula for incorporating the speed of the target ship into the sine , cosine and tan aspects?

I dont want to end up like Tangs PCO at the Inland sea, firing all 4 aft mark 18s and 2 of which broach

giving away..

Sincerely,
CS2k9

3rd one, vector analysis method. It's not a pure formula method, but it'll work. Range would cancel out of the calculations, so you don't even need it for this method.

thanks rzark will look into it.

Oh no, not math.

Oh well, that counts me out. I was sick that day, at school.
