Hi, I've been looking information about this three components, but I'm not sure if it's a bug or I'm now understanding what they do, I read the wiki and other sources and all says "ignore shields|armor|point defence, so I armed all my ships with them, but when I send them to fight it seems like it was not been working properly:

my ship have 91 missile dmg, and those Figthers have barely 7HP, however it still hitting it's defences, so it's taking 3 hits to destroy them

This is happening with kinetic and beam weapons too.
