Minimal platform optimized for the smallest number of launches. While it is not the smallest or most compact, it avoids things like underground belts or pipes or combinators to save on launches.
Can travel from Nauvis to Vulcanus and loiter there in orbit indefinitly. Please let it build a buffer of ammo before travel.
Intended as a "seed" that can recieve the building supplies for much bigger craft while holding its own in orbit. This way large ships can be build from the ample supplies at Vulcanus.
