Inside the New Mexico Community Neighbors Worrying Over a New Hypersonic Missile Factory

Residents of an unincorporated community outside Rio Rancho, New Mexico, are voicing safety concerns following the rapid development of Project Ranger, a 1,000-acre hypersonic missile manufacturing and testing facility spearheaded by defense startup Castelion.

Founded by former SpaceX executives, Castelion is constructing the mega-campus on a site located, in some instances, just over 1,000 yards away from roughly 450 properties in Rio Rancho Estates. The proximity has left local landowners anxious about potential hazards, particularly regarding the handling and storage of large quantities of explosive materials and chemical propellants.

Hazard Assessments and Safety Concerns

A hazard assessment report produced by Sandia National Laboratories under the NewMxico Small Business Assistance Program evaluated potential risks tied to the facility's operations. The analysis identified storage facility fires and propellant detonations as key scenarios. According to the report, Castelion plans to store substantial quantities of propellant, including up to 250,000 pounds of ammonium perchlorate inside covered magazines and bunkers, alongside up to 81,000 pounds of active explosive material inside hazardous integration facilities during assembly.

The report calculated that a worst-case detonation of the maximum allowed stockpile would require a significant safety buffer from inhabited buildings. Additionally, a probable test-stand fire could release toxic byproducts, including hydrogen chloride and chlorine gases. Public records requests and internal emails further revealed that the Rio Rancho Fire Department determined 17 of the 26 buildings at the Project Ranger site would be left to burn in the event of a chemical blaze due to the extreme risks posed to first responders.

Local Approvals and Financial Incentives

Local officials and state leaders have championed Project Ranger as a significant economic opportunity. Sandoval County approved $125 million in industrial revenue bonds, granted a 95 percent discount on property taxes for the facility, and abated compensating taxes on out-of-state equipment. State and local leaders, including Governor Michelle Lujan Grisham and local representatives, attended the project's groundbreaking ceremony.

However, residents argue that the approval process moved swiftly without adequate early public notification. Critics and community members point out that negotiations regarding fire-flow requirements and safety standards continued even after construction was underway.

Practical Implications and Reader Verification
