Powering the Golden Dome: Ranger’s Role in Space Superiority

Enhancing U.S. space defense through persistent presence and rapid maneuverability

At Quantum Space, we’re developing the breakthrough, scalable Ranger platform — unmatched in maneuverability, endurance, and mission versatility. Ranger can refuel other satellites, rapidly reposition across orbits, and serve as a persistent, high-performance platform for national security payloads. Unlike disposable, single-mission spacecraft, Ranger is built for 15+ years of operation — cutting long-term costs while unlocking new missions that strengthen the Golden Dome defense architecture.

Leading with Technology, Delivering Security

Quantum Space pioneers responsible leadership in space, leveraging decades of expertise to establish dominance where it matters most.

RANGER 500

Our ESPA-Grande vehicles are nimble by design. They are the data-collection workhorses of the family and play an important part in the Quantum Space ecosystem. They provide the redundancy and reliability required by military and commercial programs. The multi-modal spacecraft can spin around and capture images and collect data, while also being part of a global communications network.

Our Story

Quantum Space was founded to become the premier spacecraft and on-orbit services company. The idea was to fill a hole in the market for high mobility, high thrust, long life spacecraft. The cofounders are space industry veterans each with 30+ years of experience in the aerospace industry developing, launching, and operating complex space systems. We are building a company that lowers the barriers to entry for highly demanding customer missions.

Quantum Space is just the latest of ventures by Kam Ghaffarian, a space and energy entrepreneur who has co-founded many leading new space companies, including IBX Intuitive Machines, Axiom Space and X-energy.
