Well, the Zents perfectly supported themselves when they were on an expedition of conquest.

Now, remember, most, if not an overwhelming number of vessels employed by the UN SPACY are still Zent ships, which were configured to specifically support their size.

That, and learning Zent technology was a huge step in increasing the logistics capabilities required for prolonged expeditions into unknown space.

Spoiler for End of SDF Macross:

Oh, and lets not even forget how Earth repopulated itself after Space War I. It was virtually done by cloning en masse, with Zent machinery providing all the necessary support in the process.
