Space Program

Design launch vehicles, spacecraft, aircraft and ships in NativeCAD, then fly them through a solar system on rails: ascent, orbit, rendezvous, landing and re-entry, with real physics doing the work. A Moon mission and a fully reusable super-heavy rocket are flyable today in the open demo while the rest gets built.

• Fly what you design — Export any NativeCAD model as a flyable vehicle, with kernel mass properties and mates as joints, and let Claude help you build it.
• Missions written with Claude — Describe a mission in plain words; Claude writes it in the mission format, it is validated, and you fly it.
• A mission library you can share — Built-in and player missions in one list, import and export, and share links that carry the whole mission.
• Online multiplayer — Host-authoritative simulation so friends can fly in the same world.
• Local split-screen — Two pads, two pilots, one world on one machine.
• Replays and share links — Deterministic replays of any flight, a "replay from here" button in the debrief, and links you can send.
• More worlds to reach — A cloud-wrapped inner planet, a rust-plains world with polar caps, and a ringed gas giant with moons.
• Orbital challenges — Rendezvous with and capture a tumbling derelict, cross a debris cloud, chase an evasive target.
• A full spaceport — An original coastal launch site: orbital launch mount, tank farm, catch tower and a production site with a rocket garden.
• A 1945 battleship at 1:1 — Hull lofted from station sections, superstructure and turrets from public sources, then tuned to sail: displacement, speed, turning circle.
• A supercarrier, with catapults and wires — A 333 m carrier modelled from public data, with catapult launches and arrested landings.
• A naval base with a big dock — A sheltered harbour in the home bay with a dredged channel, piers, and a graving dry dock that floods and drains.
• Ships that float for real — Buoyancy from the kernel-computed hull, resistance, sway, yaw and roll, so every hull handles like its shape.
• Helicopters — A blade-element main rotor with collective, cyclic and flapping, a tail rotor and engine torque.
• Threats that shoot back — Surface-to-air missile sites, anti-aircraft guns and ship point defence, with a radar warning receiver and countermeasures.
• Stand in the lunar lander — The lander crew compartment laid out panel by panel from the operations handbook.
• Phone and tablet flight — Touch controls tuned for flying on a phone or tablet.
