SpaceX does not use Archer Aviation's aircraft or technology for its aerospace operations, as the two companies operate in completely different sectors of the transportation industry. SpaceX focuses on rocket manufacturing, satellite internet deployment, and space launch services, whereas Archer Aviation develops electric vertical take-off and landing aircraft intended for urban air mobility and regional passenger transit. While both companies are prominent technology innovators backed by high-profile institutional investors, they maintain independent operational boundaries and do not share commercial supply chain integrations.
