The screen snapshot below shows that the Xelosi have not only researched the Dreadnaught ship size, but also produced at least one by turn 70.  You can see the turn number in the upper right-hand corner and you can see the Dreadnaught ship in the lower left-hand corner.  They have also apparently researched Carriers as shown in the second screen snapshot below.  The 10 assault fighters give them 160 kinetic attack.

I understand that Godlike is supposed to be extremely difficult, but this is a little excessive in my opinion.
