@zebulon 1ᵉʳ, dit "le maudit" In opposite - it could have huge volume because it has so big diameter. Anyway, it's pity they didn't work on it in real.
Payload as % of rocket mass is bigger for bigger rockets generally. That's why SpaceX make SHS. Weight of structure grow, but volume is growing faster.
