SpinLaunch

SpinLaunch develops kinetic launch systems that use ground-based electric centrifuges to accelerate payloads to hypersonic velocities. The company operates the A-33 suborbital accelerator at Spaceport America in New Mexico, a 33-meter-diameter vacuum chamber that rotates a carbon-fiber arm to launch payloads at speeds up to 5,000 miles per hour. A chemical rocket engine then provides the final orbital velocity. SpinLaunch manufactures the S-200 satellite bus, a 200-kilogram-class platform ruggedized to withstand thousands of G-forces during kinetic launch. The company also operates a 12-meter laboratory accelerator at its Long Beach headquarters for component testing and provides high-G qualification services to external aerospace customers.

SpinLaunch pivoted in 2025 toward integrated satellite operations and is developing Meridian Space, a low Earth orbit constellation designed for global broadband internet services. Meridian satellites use multi-band reconfigurable reflectarray antennas for dynamic beam steering. Near-term Meridian deployments use conventional chemical rockets, while SpinLaunch continues developing an orbital-scale kinetic accelerator for future operations. The company was founded in 2014 and maintains headquarters in Long Beach, California. Leadership includes CEO Massimiliano Ladovaz, formerly of OneWeb. SpinLaunch has conducted flight tests and qualification programs for NASA, the Department of Defense, and commercial partners including Airbus U.S. Space and Defense.
