ABL Space Systems, founded in 2017 and headquartered in El Segundo, California, United States, raised a $200 million Series B expansion round in October 2021 that valued it at approximately $2.4 billion. The company is building the RS1 rocket and GS0 container‑based ground system to provide low‑cost, rapid‑deployment launches for small satellites. With major backers such as T. Rowe Price, Fidelity Investments and Lockheed Martin Ventures, ABL Space Systems is poised to serve both commercial and government launch markets and scale responsive access to orbit.
