Actually, I was right.
Taken from the 3rd entry of the story so far:
We’ve done our best to prepare them for the war they’ll face. Along with the Ark itself, the installation will contain a new and deadly arsenal. While we race to complete the cloning device, others have been developing cutting-edge weaponry based on the Narak’s superior technology. Thanks to their help, when the Ark activates, so too will its munitions plant.
Hmm... this makes me seem like a snot, on second reading. But yeah, it does say the weapons built in the Ark are based on Narak tech.
