Frequently Asked Questions

  • What is Project Ranger?

    Project Ranger is a manufacturing facility that will produce solid rocket motors, conduct static tests, and assemble components to produce finished rounds, reinforcing New Mexico’s position at the forefront of defense innovation.

  • How many jobs will Project Ranger create?

    Project Ranger is expected to create 300 high-wage, high-tech manufacturing and engineering jobs. Castelion may hire additional staff in the future based on production needs and demand for its systems.

  • I applied to the New Mexico general posting. What’s the status of my application?

    We’ve received an overwhelming amount of interest in our New Mexico opportunities, and we’re grateful for the enthusiasm from so many talented applicants. That initial posting was created to gather candidates for future roles related to Project Ranger. We are now beginning to roll out specific positions, with a significant hiring ramp expected by the end of this year. As new roles open, our team will review previously submitted applications and reach out to candidates whose experience aligns with upcoming needs.

  • How will Project Ranger impact New Mexico’s economy?

    Project Ranger is expected to generate over $650 million in economic output in New Mexico between 2026 and 2036.

  • Why did Castelion choose Rio Rancho and Sandoval County for Project Ranger?

    We chose New Mexico because it has the deepest hypersonics expertise in the country, from Sandia to Los Alamos to White Sands. Rio Rancho and Sandoval County add workforce, infrastructure, and a committed economic development partnership.

  • Will Castelion work with local schools and colleges in New Mexico?

    Absolutely, and we’re already doing so. We seek those interested in engineering, skilled trades, and advanced manufacturing careers.

  • When will Project Ranger begin operations?

    We’ve begun hiring local employees and have established temporary office space to support our growing team in New Mexico. Castelion expects to begin preliminary production operations early next year, which is expected to drive an increase in open positions to support the ramp-up.

  • What are the safety standards at Project Ranger?

    Project Ranger will adhere to rigorous federal and Department of Defense safety standards. Safety is incorporated into every aspect of the facility, including how it is designed and constructed, how our teams operate and maintain equipment, and how materials are safely managed. These standards are designed to protect our employees and the surrounding community.

  • How will Project Ranger manage hazards to protect nearby communities?

    Project Ranger will protect nearby communities by systematically managing hazards through strict adherence to safety and quality-assurance protocols. We will only conduct static motor tests that are contained, short in duration, and produce low-volume noise at distance. There will be no chemical synthesis, no launches, and no detonations.

  • Will Project Ranger impact groundwater or air quality?

    No, Project Ranger won’t impact groundwater or air quality because all materials will be sealed, contained or abated. We will conduct independent monitoring and adhere to all federal, state, and local environmental statutes.

  • What inspired Project Ranger’s name?

    Project Ranger was inspired by NASA’s Ranger program, a series of uncrewed missions in the early 1960s that set the stage for the Apollo moon landings and subsequent decades of American leadership in aerospace and defense.
