I totally agree with that.
I haven't played with the USN dds, but I do love playing the Minekaze for its stealth gameplay and destructive power. I always prevent my AA turrets from firing (except if I'm all-in, but in general, these are useless and light you up...), and try to fire torps on the BBs that are not paying attention.
Careful though, because some ennemy DDs might spot you and place you in a bad spot, and will reveal the torps which will then become useless. Map awareness of the ennemy DDs is vital.
Also, I find the Minekaze really fragile, because you get the navigation module down SO often it will makes you cringe. I don't know about the others, but I can assure you the T4 ability to manoeuver even when the module is down will save your life.
To make the best of this ship, I would recommend using islands to hide and fire torps along them, so the ennemy will only spot them at the very last moment which is too late, and stay as far as possible from every other ship to remain undetected. You will grant your teamates vision on the ennemy ships, and will have higher chances of hitting with torps.
If you manage to stay undetected, you can eventually pass behind the ennemy lines and take down the CVs or slow BBs really easily, because they usually are focused elsewhere and don't pay any attention to their ship.
From what I experienced, You and ennemy DDs will spot yourselves when within 5km range, and then ennemies will spot you if you are within 6km range.
Planes will spot you withing 4.5 to 5km, it actually depends.
It means you have a really good spot to fire torps between 6.5 - 8km range and stay undetected.
Remember to keep your consummables for when it's needed only(for example if you see planes coming and you won't have enough speed, using the boost to avoid being detected is a good idea).
Last trick I found really neat, is to fire torps with the large cone on the opposite direction of where ennemy DDs will go, because they usually tend to fire and turn back (they will expect you to have fired your torpedos on their initial trajectory and turn back to avoid them) and then run into your torps. Tried it several times, and it worked out sometimes.
A good thing too is to launch torps from a smoke screen, they don't spot them in the smoke and can run into one, but there it's more about luck.
Hope this helped
