So I figured out the strength of the
Voyager's armor, and it can take at least 25g to each section of plating (in mouse-size; in real-life somewhere in the ballpark of 520kg, probably more).

That's insane—enough to take a full second of heavy phaser fire
to each plate. Here's the link to my article:

Voyager has armor that is strong, but not that strong. However, I wondered all three Kingdoms, working together, could take out a ship with incredibly tough plating.
We'll give
Voyager 6 150W phaser cannons (35g per shot), 2 super-torpedo launchers (200g per shot), and 1 sonic tractor beam. Its shields can withstand 250g before they buckle, and its armor can take up to 80g.
Round I:
Voyager vs 3 battlecruisers, one from each Kingdom.
Round II:
Voyager vs a Star Destroyer.
Round III:
Voyager vs literally everything the Kingdoms have.
What do you think?
