Fortastra is a spacecraft engineering company developing autonomous orbital defense systems. Based in Torrance, California, the company builds low-cost, maneuverable spacecraft designed to protect critical space infrastructure. Its systems use commercial components and advanced autonomy to navigate in orbit, detect anomalies, and execute protect-and-defend maneuvers without direct human control.
The company operates across the space defense, government, and commercial space sectors. Its technical domains include spacecraft engineering, autonomy, sensor hardware, and software development. Fortastra has raised $8M in seed-stage funding.
The team includes veterans from SpaceX, Hermeus, Relativity Space, Astrion, and Divergent Technologies.
