Huh?
the DDs already accelerate WAY too much... how can a request like that be made, if the acceleration is already off?
1000 tons of steel can only be moved so much... avoiding a well shot eel at 400m leading you... should put an end to your DD career.
I propose a different pattern after depthcharging... just let the DDs zig zag after dropping the ashcans, and make some random movements...
GWX:
DD =
drop depth charges,
make turn.
VII/b =
avoid depth charges at periscope depth,
wait DD turn, set Torpedo depth and speed Maximum
shoot Torpedo at Bow Wave of DD.
wait for impact below front ammo storage
drink beer, watch fireworks
repeat as necessary
If we could have half a dozen ways how the DDs make an attack run, one could not predict their post-attack reactions so easily, and thus nail them every single time...
(up to early 1941 that is)
