For a basic ship that there's no need to be ashamed of ... A sublight drive, two ion engines at least to get it off the ground, since I can't build a hyperdrive without very specific materials. Shield generators, transparisteel, solar-collector power lines would require an ionization reactor, I could attempt to construct a girondium-colium cell to brace any arrays but that would mean an electromagnetic gyroscope to counteract the moon's gravitational pull ...

Realistically, it would take months to build such a craft even if I had twenty troopers and the perfect materials. We'd be working from scratch, off the cuff.
