At Spaceport America in New Mexico on 22 October 2021, SpinLaunch conducted the first vertical test of their accelerator at 20% of its full power capacity, hurling a 10-foot (3.0 m) long passive projectile to an altitude of "tens of thousands of feet". This test accelerator is 108 ft (33 m) in diameter, which makes it a one-third scale of the operational system that is being designed.[10][11][12]
