Do your defenses and ships shields and armour “regenerate” after every round in a battle?
Yes and no. :) After every round of battle, your shields will regenerate back to full. Your armor is the “hit points” of your ship, and these do not regenerate during the battle. However, after the battle, any ships that took damage are repaired back to full status.
Furthermore, once a ship has lost more than 30% of its hitpoints, it has a chance to self-destruct (due to battle damage I guess).
Hull Points (hit points) and Technology
Each tech advance increases effective protection by 10% (shield and armour).
For Example: A large cargo has a base structure of 12,000. 30% damage means after 3,600 damage there is a risk of it blowing up.
Armour 5 adds 50% of the base points, so 5 * 10% * 12,000 = 6,000
Giving a new hull points of 18,000.
Your Large Cargo can now take 30% of 18,000, or 5,400 damage before there is a risk of it blowing up. This gives you an extra 1,800 points of damage you can absorb before you run the risk of blowing up.
Shield Power and Regeneration
For example: A heavy fighter (shield level 0) vs a heavy fighter (shield level 2).
Base shield is 25, so shield power is 25 + (25*2*10%) =30
NOTE: Shield is a little odd in that unless you have at least level 1 you get no shield at all if speedsim works right.
Now in battle, the first 30 points of attack power is absorbed by the shield before it hits your Heavy fighter. (each round)
Given that once you pass 30% damage there is a risk of blowing up its no guarantee of victory. But higher levels of shield and armour definatly give a nice boost to survivability.
