TD changed ships' strength parameters in ships.ini to make weaker at version 4.11 update.
In 4.11.1 , ships can sink more easily by bombing than 4.10.1 or earlier.
But the ships.ini at HSFX6 keeps 4.10.1's strength.
Here is TD 4.11.1 ships.ini strength parameters.
You can use this in HSFX6 by rewriting(replacing) the beginning of your ships.ini .
