Executive Overview
For Sally Schultz, a single mother of four, purchasing a half-acre plot of land in the unincorporated community of Rio Rancho Estates, New Mexico, felt like hitting the lottery. Following a difficult divorce, Schultz sought a fresh start—a place to establish stability, build a homestead, and plant roots away from urban pressures. For just $3,500, she secured a rural parcel situated conveniently close to local elementary schools and community parks. Within a remarkably short period, she transformed the arid dirt into a thriving garden, coaxing harvests of corn, squash, and green chile from the soil. This modest, affordable plot became her sanctuary—a second chance at life.
That sanctuary is now shadowed by the architecture of modern warfare.
A few thousand feet away from Schultz’s property line, construction crews are rapidly finalizing Project Ranger: what its creators proudly market as America’s largest dedicated hypersonic manufacturing and testing facility. Spearheaded by Castelion, a defense tech startup founded in November 2022 by three former SpaceX executives, the mega-campus is slated for completion by the end of the year.
Yet, for the roughly 450 property owners in Rio Rancho Estates whose homes sit barely 1,000 yards from the perimeter of the facility, the arrival of Project Ranger represents an existential threat. Far from a standard industrial neighbor, Castelion’s new home will house massive stockpiles of volatile solid-rocket propellants and high explosives. Internal hazard assessments, municipal records, and leaked safety evaluations reveal a deeply troubling narrative: a fast-tracked defense project backed by state and local politicians, greenlit despite severe safety hazards, and constructed with minimal public oversight or guaranteed protections for the low-income residents living squarely within its potential blast zone.
Detailed Chronology: From Secret Inquiries to Groundbreaking
The path that brought Castelion to the edge of Rio Rancho is a masterclass in corporate maneuvering and political expediency, marked by rapid relocations, clandestine negotiations, and a profound lack of community engagement.
The Nevada Departure
Castelion’s journey toward Project Ranger began thousands of miles away. In August 2023, the startup applied to build a rocket-manufacturing plant in Churchill County, Nevada, operating under the corporate pseudonym Pallas Industrials. Signed by Chief Financial Officer Andrew Kreitz, the special-use application openly detailed the company’s intent to manufacture rocket motors and conduct open-air ground-testing up to eight days a month.
Faced with the proposal, Churchill County officials did what municipal governments are chartered to do: they pushed back. Staff members produced an eight-page analysis demanding stringent safety protocols, rigid environmental controls, and clear testing conditions. Rather than complying with the oversight, Pallas Industrials—now operating under its actual name, Castelion—abruptly pulled its application and packed its bags.
By early 2025, soil-probing trucks had materialized in the desert landscape of western Rio Rancho. Behind closed doors, Castelion was already deep in negotiations with New Mexico economic development officials to secure a home for its massive manufacturing ambitions.
Bypassing Public Scrutiny
In August 2025, months before Castelion publicly acknowledged its plans for New Mexico, State Senator Jay Block appeared before the Sandoval County Commission to advocate for massive financial incentives. Block, a Republican whose district includes Rio Rancho and who previously served as a county commissioner, was a staunch champion of the project.
Acting on these pitches, the Sandoval County Commission approved a staggering $125 million in industrial revenue bonds, granted an extraordinary 95-percent discount on property taxes for the missile maker, and abated compensating taxes on out-of-state equipment.
The public, however, remained largely in the dark. It was not until October 2025—long after the financial frameworks were codified and land deals struck—that Castelion held its first public information meeting.
"All of this happened behind the scenes," notes Zachary Darden, a Rio Rancho resident who ran an unsuccessful mayoral campaign opposing the development. "By the time it was public, it was already a done deal."
The VIP Groundbreaking
By November 2025, municipal machinery was working in overdrive. Rio Rancho Economic Development Manager Alberto Solís coordinated a four-day networking trip for Castelion CFO Andrew Kreitz, scheduling appearances at local Chamber of Commerce mixers and meetings with the Sandoval Economic Alliance.
Shortly thereafter, Castelion held an exclusive groundbreaking ceremony for the 1,000-acre Project Ranger facility. Local residents—the very people whose backyards abut the bunker sites—were pointedly not invited. In stark contrast, the guest list read like a Who’s Who of New Mexico’s political establishment: Governor Michelle Lujan Grisham, then-Rio Rancho Mayor and gubernatorial candidate Gregg Hull, U.S. Senator Martin Heinrich, and State Senator Jay Block all stood shoulder-to-shoulder to celebrate the arrival of the defense giant.
"Castelion’s Project Ranger shows what a strong public-private partnership can deliver for a local community," declared Rob Black, New Mexico’s secretary of economic development.
Supporting Context & Metrics: The Defense Tech Darling
To understand how Castelion commanded such swift, uncritical political adoration, one must look at its meteoric rise in the modern defense technology ecosystem.
Castelion has quickly become a darling of venture capitalists and military procurement officers alike, capitalizing on the Pentagon’s urgent push to pivot away from legacy defense contractors toward agile, software-driven hardware startups.
Financial Velocity and Valuations
- Valuation Surge: Castelion’s valuation has skyrocketed to $13 billion, representing more than a fourfold increase over its Series B valuation of $2.8 billion recorded just a year prior.
- Federal Contracts: The startup has secured over $500 million in U.S. military contracts within an 18-month window, firmly entrenching itself as a key supplier in the Pentagon’s "Arsenal of Freedom" initiative.
- The Hypersonic Advantage: Hypersonic weapons—defined as systems capable of flying at Mach 5 (five times the speed of sound) or higher—are a primary focus of modern geopolitical competition. Traditional systems, such as the U.S. Army’s Dark Eagle, carry a prohibitive price tag of roughly $41 million per missile, according to a 2023 Congressional Budget Office study. Castelion’s flagship product, the Blackbeard solid-rocket-powered missile, was initially marketed as a disruptive alternative priced at an astonishingly low $384,000 per unit.
Price Inflation and Scale
Reality, however, has begun to outpace initial marketing claims. The Navy awarded Castelion a nearly $50 million contract for full-scale Blackbeard prototypes, followed by an additional $23.4 million in June to supply the first 50 operational units. By August, the Navy doubled down with a $90 million manufacturing services contract for those same 50 missiles—pushing the total to $163.4 million, or roughly $3.3 million per unit. In September, the Navy piled on another contract worth up to $200 million.
Despite these astronomical sums and the release of promotional photographs, Castelion has kept concrete performance data under wraps, leaving independent defense analysts with zero verifiable test data to evaluate the weapon’s combat efficacy. Nevertheless, Project Ranger is designed to rush these unproven systems directly into mass production as early as next year.
Official Statements and Safety Hazards: The Sandia Report
The true peril of Project Ranger only came to light through an administrative blunder. In June 2025, Sandia National Laboratories produced a hazard report evaluating the safety risks of the facility as part of the New Mexico Small Business Assistance Program.
When the report was later requested under the Freedom of Information Act (FOIA), lab officials attempted to redact sensitive details. Instead of scrubbing the underlying data layer, however, they merely applied black digital highlights over black text—allowing anyone to uncover the full, unredacted contents simply by copying and pasting the text.
The Worst-Case Scenario: Explosions and Blast Radii
The leaked Sandia report paints a sobering picture of industrial risk placed directly adjacent to civilian rooftops. Castelion plans to store massive quantities of solid-rocket propellants on-site, including heat-sensitive chemical oxidizers like ammonium perchlorate.
According to the safety assessment:
- Storage Bunkers: Castelion is authorized to store up to 250,000 pounds of energetic materials within covered magazines and bunkers.
- Active Integration: Outside those bunkers, the facility is permitted to keep up to 81,000 pounds of active explosive material simultaneously inside hazardous integration facilities during assembly.
- Blast Hazard: A catastrophic detonation of the facility’s maximum allowable explosive stockpile would require a safety buffer of nearly nine football fields from the nearest inhabited building. Sandia’s models calculated that a worst-case blast would shatter large windows nearly four miles away and carry a 3.2 percent chance of inducing minor eardrum damage to individuals just 400 yards from ground zero.
The Chemical Hazard: Toxic Smoke and "Let It Burn" Policies
An explosion is not the only—nor perhaps the most probable—threat identified by safety analysts. The Sandia report notes that a fire at the facility’s test stand represents the "most probable foreseeable hazardous event."
A chemical fire involving solid rocket propellants would release a dense, toxic plume laden with hydrogen chloride and chlorine gas. Both substances are intensely corrosive, capable of inflicting severe burns upon human skin, eyes, and respiratory tracts. Short-term inhalation of high concentrations causes acute chemical lung damage and asphyxiation.
Crucially, internal emails obtained via public records requests reveal that the Rio Rancho Fire Department formally determined that 17 of the 26 buildings at the Project Ranger site would be deliberately left to burn in the event of an active fire. The chemical hazards are deemed so extreme that local firefighters would be legally barred from entering the high-risk structures.
Compounding these dangers, public records show that Castelion was still actively negotiating basic fire-flow and safety response standards with municipal officials between March and May—even as heavy construction on the facility was already underway. Site developer Bryce Barlow admitted in a March email that the company had not finalized its water-flow requirements, offering to discuss the matter informally. Ultimately, City Manager Matt Geisel streamlined the process, replacing hard safety metrics with a vague memorandum of understanding.
"Great news! Saves all of us both legal bills and headaches," CFO Andrew Kreitz wrote in response.
Future Outlook: Collateral Damage in the Defense Boom
As construction on Project Ranger races toward its year-end completion deadline, the human cost of America’s resurgent defense manufacturing boom is coming into sharp focus in the New Mexican desert.
Incidents across the country underscore that these industrial risks are far from theoretical. In June, a test run of an ammonium perchlorate-based rocket motor at an Anduril facility in Mississippi ended in a massive explosion. Earlier in May, an overheating chemical storage tank at a GKN Aerospace facility in Garden Grove, California, forced the emergency evacuation of over 40,000 residents.
For the residents of Rio Rancho Estates, however, evacuation is not a simple logistical option. As a designated low-income, rural community, property owners here bought into the desert precisely because land ownership was within financial reach. Relocating means abandoning homes, gardens, and hard-won stability that cannot easily be replicated elsewhere in today’s inflated real estate market.
"This land is affordable for people who need it," says community member Jason Clifford, capturing the bitter sentiment of his neighbors. "We were sold out by our local officials."
While defense executives celebrate multi-million-dollar government windfalls and politicians cut ribbons for high-tech manufacturing campuses, Sally Schultz and her neighbors are left staring out their backbones at heavily fortified bunkers. In their quiet desert haven, the distant rumble of progress sounds less like economic revitalization and much more like the footsteps of an impending storm.
