Some games have a "damage resistance" mechanic, often granted by armour. With this mechanic, you simply subtract a damage resistance number from any amount of damage rolled in one combat round. If the result is zero or less, the defending item/being takes no damage at all.
This can be appropriate for things like vehicles or buildings, where hitting them with something like a sword would typically do no damage worth mentioning. It means you need to find some other way to damage the thing.
Commentary by memnarch (who has not seen the movie)
No noticeable damage, no surprise there. Probably has at least 14 defence dice, if it's not just simply plot armor that needs to be worked around instead. Like maybe actually aiming at important looking or fragile components like the windows is required. Or maybe flying inside the hanger and shooting the place up! That's worked at least twice before, sort of, so that would be a reasonable thing to try again.
This is quite the variety of helmets being worn as well. I wonder if there's anything meaningful about the designs like "Allan's" being black instead of white, or if it's just something fun the movie designers did. I bet it's come in handy for making these comics at least.

Lieutenant Bastian: Direct hit!
Ello Asty: But no damage.
Jessika Pava: Are we sure this is the right approach?
Allan: Yeah! If it were easy to destroy, that’d mean it was unimportant!
GM: So that’s why my adventure plans feel unimportant.
