The Vorkosigan spaceships design system is taken from Spaceships.
Both use decade-scale ST, HP, DR and weapon Damage, ie your warship with dST/HP 100 has 1000 player character scale ST and HP.
It's 1Gj plasma cannon does 4dx5(5) dDamage vs it's dDR10 gives an average damage of 68dHP. Or in player character scale, 4dx50(5) vs DR100 and 680HP injury.
The dHP are the vessel's total, with each section being more akin to a body's limbs. Weapon damage is compared to the original dHP and tallied as for a pc but enough damage in one hit can disable or destroy that section, cf Major Wounds.
Surge: IDHMBWM a Major wound calls for a HT check or system shutdown. I'll check my books asap for the ship equivalent, unless someone ninjas the answer:D
The HT stat isn't scaled:D
cScale is something you're more likely to see in high-value Supers games.
