I agree with the first post of Observer i could add some tactics suggestions :
For the first attack :
- instead of keeping your sub on a perfect 90° from the path of the convoy, try to present yourself on a 80°. This will considerably lower your gyro angle, and anyway you can't shoot at a 0 bearing because the targets overlap.
- try to get closer. 450-500m instead of 800 will do a big difference and will reduce the timing between the impacts but most important you're greatly increasing your accuracy on some tricky fire solutions like T2. At night it will be easier not getting spotted, but anyway, when everything is set for you, just lower your periscope, follow on hydrophones the bearing of the closest ship, when it reaches a bearing you choose that gives you a close distance but enough time to prepare to fire, raise it and start aiming. This will greatly reduce the chances of detection before the launching.
- Prepare a plan of fire : assign a torpedo tube for each target and prepare it to be fired on that specific target you choose for that tube. If the angle of fire is not between 330-30° you don't want to go for impact anyway. For example on your drawing, T1 and T2 Must be treated with magnetic torps. So set all the corrects depth for magnetics torps on your sequence of fire in advance, you don't have time to do it between each shot, or you'll be too late. Then just do your planned sequence : for example torp 1 on T2 torp 2 on LIb, torp 3 on T1, torp 4 on T3.
- I suppose you know that, but lower immediatly your periscope after last launching. Sometimes you get spotted not before firing but when you're waiting to see you're firework. Just raise it some seconds before the impact if you really want to take a look.
Normally it works
