U.S. spacecraft manufacturer Quantum Space completed a critical Manufacturing Readiness Review (MRR) for its upcoming Ranger Prime mission, scheduled for launch in June 2026 from Vandenberg Space Force Base in California.

Quantum designed its Ranger platform as a uniquely maneuverable spacecraft for defense customers and commercial operators. With its own in-house built propulsion system, modular flexibility, and extended service, Quantum promotes Ranger as being able to “outmaneuver legacy satellites and operate dynamically across diverse mission sets.”

“Over the last three years, Quantum Space has focused research and development on designing, testing, and qualifying the Ranger fleet and stand ready to meet the President’s challenge to defend the nation from and within space,” Quantum Space CTO Phil Bracken said in the MRR announcement. “With the Manufacturing Readiness Review complete, our team will begin spacecraft assembly and testing ahead of shipment to the launch services contractor in early 2026.”

The upcoming Ranger Prime mission involves the company’s Ranger 500 spacecraft. The mission aims to validate its on-orbit performance and remote proximity targeting operations for the U.S. Space Force.

“Our Ranger Space Superiority Vehicle fleet, with its game-changing propulsion capability and payload capacity, can form the backbone of America’s Golden Dome space element,” said Richard Matlock, Senior Vice President for National Security Space Programs at Quantum Space.

Quantum Space is currently scheduled to launch its largest flagship Ranger variant – the Ranger 2000 spacecraft – in December 2026.
