And even trugh the explosion deals damage to other internal components of the CASE-protected section the engine slots can't be crited and thus you should survive until you lose the ST.
I used half-ton packages to increase the number of components which can recive crit-damage.
Afaik it is random which component recives crit damage, that means the more components, the higher is the theoretical HP in that section and in case of an ammo-explosion you loose less ammo.
Please feel free to correct me if I'm wrong with that.
