Castelion has announced plans to build a hypersonic manufacturing campus in Sandoval County, New Mexico.

The company, which develops hypersonic strike systems, is investing more than $220 million in the project and expects to create approximately 300 high-paying manufacturing jobs.

The project, known as Project Ranger, will span 1,000 acres and include 21 buildings dedicated to hypersonic manufacturing operations. Once complete, the campus will support solid rocket motor manufacturing, static testing, and final assembly of hypersonic weapons.

The first building is scheduled to be completed in summer 2026, with all facilities ready for production by the end of 2026. The site is designed to enable high-cadence production to support domestic manufacturing capacity. The project represents more than $220 million in private investment and is expected to generate significant long-term economic impact for the region.

What people are saying

In a recent quote, Bryon Hargis, CEO and Co-Founder, Castelion, said,
“We chose New Mexico for its unparalleled technical talent and history of scientific achievement. Project Ranger represents a renaissance in American manufacturing, delivering the advanced systems our country needs. We're proud to partner with a community that has powered some of our nation's greatest leaps forward. We have a bright future together.”

U.S. Senator Martin Heinrich said, "this is a great example of what New Mexico does best: Developing cutting-edge science and technology and manufacturing it right here in our state. As New Mexico's senior senator, I will keep working to further bolster New Mexico's bases, defense research labs, and private industry partners so we can keep excelling in emerging defense capabilities."
