 reaches an altitude of at least 100km (the

This question is about vehicle designs descended from the existing designs of Starship - i.e. if they make substantial changes or rename the vehicle, it still counts. But a vehicle based on e.g. the Falcon 9 would not count, even if SpaceX called it a Starship.

(This question's criteria is chosen to be less ambiguous than the questions about whether it reaches orbit, where it is unclear whether a planned borderline-orbital test flight, with perigee within the atmosphere, counts as orbital.)
