USN Convoy Attacks

I'll assume you have speed and course plotted. If seas are smooth, I'd use a Vector Analysis attack using sonar at a depth of 149 feet (a foot over max firing depth). So, range doesn't matter. Compute your attack 2deg off true to lessen the 90deg dud factor. Sonar contacts are at MOT or at the screw (I've never figured out which, for sure), so at 3000 yards lead your target by 4degs if under 10kts for the first shot of your salvo. Adjust your gyro angle ahead by 1deg for the 2 successive shots.

External booms and internal whoops should follow...
