A dedicated medical bay and research ship — surgery-ready care, isolation, and a lab for studying how the human body actually holds up over years in orbit.
A single Starship is only so big — so we stopped trying to cram an entire station into one hull. Instead, each Starship in the cluster becomes a specialized module. Five purpose-built ships dock to the Oakheart at their core and together become the Oakheart Orbital Complex.

A dedicated medical bay and research ship — surgery-ready care, isolation, and a lab for studying how the human body actually holds up over years in orbit.
The one that feels like home. Private quarters, a curved lounge, a galley to gather in — the leisure and normalcy that make long-duration living sustainable.
An observation and experiments ship, ports aimed down at Earth and out at the dark, purpose-built for the science that only microgravity makes possible.
A working lab and fabrication deck — benches, glove boxes, printers, and robotic arms. If it needs to be built, tested, or repaired, it happens here.
Food and stores. Tiered hydroponic gardens under grow-light glow, dry-goods vaults, and water recycling — the pantry and greenhouse of the complex.
Each Starship keeps the exact footprint that once bolted to the Super Heavy booster — no new airframe, no exotic parts. Give each ship one job and it can be outfitted, launched, and swapped on its own. Lose a module and the other four keep the complex alive.
