I had read of the Americans adopting aggressive submarine tactics against the IJN during WWII.
This approach was known as "down the throat" and entailed the US sub inviting attack by giving away it's position and then firing a full spread from the bow tubes at the charging destroyer, apparantly it was quite successfull.
How is possible ? I thought that firing directly head on was not a good way to achieve a hit.

I always do it in sh2,i dont know would i chance it in real life though,would i like to waste 4 torps on a destroyer though,fire only one torpedo and if its a dud you could be a goner,
destroyers are the enemy.

"Down the throat" and "up the kilt" shots were only done when absolutely necessary. If there's only one escort you might try to sink him before tackling his sheep, but it was usually avoided. There was one sub (I forget which) who came upon a convoy at night heading right for him. With no time to set up a shot, the skipper ran his boat right down the middle of the convoy at flank speed, firing all his torpedoes, deck gun and AA guns until he was behind them. I don't remember what the results were, but what a fight.

It is possible but a risky tactic.

When the submarine and the destroyer are charging head on the detroyer is presenting only a very narrow silhouette.
If your aim is slightly off or the destroyer manouvers slighly the torpedo has a high chance of missing the destroyer.

If such a tactic would be common then I assume that the destroyers would take a zig-zagging approach to the submarine.

4 torpedo spreads are also a costly way to deal with escorts.
Especially since that means that there would be 4 torpedoes less to fire at the transports which are your real goal.
And reloading 4 tubes will give the enemy some more time to hunt you.

If the submarine fires too close to dive and turn hard the submarine may get depthcharged, hedgehogged or rammed by the destroyer.
If he fires further away the chance of a hit is lower.

It works in SH2 but I think that this is mostly due to the automatic TDC.
If you can't just lock on to the target to get a gyro angle, setting up a shot would be really hard unless both ships are heading straight for eachother.
