All focus on whether the submarines are underpowered or underpowered, a subject long debated and discussed, and none makes mention of the unrealistic use of the secondary slots of the BB and CV.
Gentlemen, historically and during the time in question, the secondary slots, both BB and CV were dedicated to anti-aircraft coverage, leaving their escorts anti-submarine coverage, in the case of BB, and their escorts and torpedo planes in the CV case.
If you consider an aberration the capacity and management of the air, the number of torpedoes of an SS, ..., the total distortion that is given to the secondary slots of BB and CV or the use of sonarman in CV is even greater.
For an SS, the intimidating power of a BB or a CV were not their main weapons (cannons and planes), much less unreal secondary ones, but their escorts. And it is really aberrant to have to use almost the same torpedoes to sink a bulged APA (8) as a BB or CV.
The one with the submarine, the torpedoes and their stealth.
Some say that a BB cannot escape the harassment of an SS, that it cannot disappear, that it cannot sink, ignoring the fact that it has speed and overhead, better damage recovery and better overhead recovery.
Assuming that anyone can teach you something new at any given time, do you think that you don't try to eliminate the escort in the first place? Now answer me, how do you do when they detect you being out of the range of your torpedoes under the unreal rain of HH that the BB throws at you, also out of your range?
46 thousand games of studies, tests, different tactics, learning from those who subs are harder or more skilled, the movements of each player, how that or another BB plays, the movement of that potentially dangerous ff or dd, to observe the tempo of the game, to anticipate their movements, when to roll or retreat, how to play with each sub and how to play against each sub, to observe the "Russian subs school" (betep, vampir85, begi76, I_bon, hitachi88, ...........), to see altsein, greenmarine, marineq, aircraftcarrier play with the ss6 km, weberusa with the rm.
Do you take people for fools?
