How did the T-61 survive?

[Tigerspook]

I guessed where the red T-61 likely was and dropped off a full load of "speculation" torps.  I got 2 hits on a T-61.  He then flooded a little. To my surprise, the T-61 survived.  How did this happen? My torps would have done 32k damage against the maximum 16,800 life on the T-61. There was a slight time delay, maybe 2 seconds, before the 2nd hit.  So it is clear that I hit him with torps from different launchers.  But best case, he would have taken 16,500 damage from the first torp and the flood, and less than 300 damage from the 2nd torp??  The T-61 lived and was not immediately killed by the La Gal.  I did not live - the T-61 got me within seconds with its own speculation torps!

The numbers you are referring to are the maximum damage the torpedos can do, but i believe there is varied damage number the torpedos do based on where the torpedos hit.  Every ship also have a torpedo reduction coefficient that reduce the torpedo damage.

If the torpedos hit in the same section of the hull, there may also be saturation, which reduces the damage done by the second torpedo, allowing the t61 to have enough hp left to survive a 300 hp flood and retaliate with 2,700 hp left.

 

ships that have torpedo protection will also reduce the damage torpedos do to the ship by a certain amount, able to be seen in the port

Damage saturation is a thing with torpedo hits.  I think you were just unfortunate enough to hit the T-61 in the same hull section with both torps.

Torpedo damage is listed as to an unprotected destroyer’s side. Two hits to the bow would be less than half the torpedo’s base listed damage.

[warheart1992]

First torpedo hit nails an extremity, bow or stern. The HP of this module is reduced to zero, so torpedo doesn't do full damage. 

Second torpedo also hits the same extremity, dealing massively reduced damage.

Used to be that after HP of module hit zero you could take zero torpedo damage.

DDs can take a torp at each extreme end of the ship and survive.

Damage saturation.

Here's some literature too on the subject.

The most likely explanation, both torpedoes hit the same section of the ship.

An extreme example of damage saturation.
