I can’t even see the number because the text goes off the screen
You can solve this by going into the various tabs on the left side of the tactical screen and selecting the Contact tab, then checking the “Group Contacts” check box.
In case it is not clear from the other responses, you are triggering the enemy to fire their AMMs at you. This can often seem overwhelming but each missile only does 1 damage if it hits. It is very much possible to just tank that damage because it is spread all over your ships and their armour. However, ten ships with only 53 point shields and 8 layers of armour are not enough, as you said. My assault ships have 20 layers of armour and at least 100+ points of shields - but more is preferable.
Remember, Aurora is just as much about preparation than it is about execution, if not more so. It is entirely possible to get into fights that are impossible to win. It doesn’t mean that the game is over, it means you need to improve your ship designs, your fleet composition and size, and finally perhaps your tactics. All play an important part.
