Summary: Colorado’s defense sector is expanding, with growing investment in space and national security. The companies on this list have been selected to develop everything from missile-warning satellites to space-domain sensors for U.S. defense programs.

Colorado’s defense industry is coming into its own, particularly as space, missile warning and national security technology become increasingly central to the country’s defense strategy. The nation’s second-largest aerospace economy, the state is home to three space force bases and major commands, including U.S. Space Command and NORAD.

All told, the aerospace and defense sectors in Colorado collectively generated more than $46 billion in federal funding in 2025. That capital drives local breakthroughs in satellites, cybersecurity, weapons systems, advanced manufacturing and defense software, led by standout companies — like the ones below — across the Centennial State.

Top Defense Companies in Colorado

United Launch Alliance puts national-security satellites into orbit, with its Vulcan rocket now certified for U.S. Space Force missions. Headquartered in Centennial, ULA was awarded 40 percent of the Space Force’s latest National Security Space Launch procurement for the country’s most technically demanding missions.

 

The Aerospace Corporation is a trusted technical adviser behind many U.S. space programs, tasked with testing designs and analyzing threats before systems reach the field. Its Colorado Springs Space Warfighting Center is a 90,000-square-foot facility where engineers use digital twin simulations, orbital threat modeling and secure wargaming suites to validate satellite architectures and command-and-control software.

 

Northrop Grumman builds military space systems that can detect incoming threats and help commanders understand what is happening in orbit. It produces more than a million U.S.-made microchips each year for secure defense platforms, and is best known for the B-21 Raider stealth bomber. Northrop Grumman’s Colorado operations span Aurora, Boulder and Colorado Springs, where its teams work on missile defense and the Sentinel program.

 

York Space Systems is scaling up satellite production for defense customers, using commercial-style manufacturing to put spacecraft into service faster. Founded in 2012, the Denver-based company has already flown 74 missions and, in 2026, expanded into new national-security work, including Space Force programs for tactical communications and space-based data networks.

 

Boeing keeps military communications running through its Wideband Global SATCOM network, which provides high-capacity, secure connections for U.S. and allied forces. In Colorado Springs, its teams operate and engineer the ground systems for the 13 WGS satellite constellation, including the software and databases used to control their missions.

 

Lockheed Martin builds some of the systems the U.S. relies on to operate in space, including GPS satellites, missile defense and NASA’s Orion spacecraft. Its space division is based in the Denver area, with a 20,000-square-foot clean room at its Waterton campus designed to support production of as many as 180 spacecraft a year.

 

Sierra Space builds satellites, propulsion systems and reusable spaceplanes for military and national-security missions. Based in Louisville, the company won a contract worth up to $798 million to deliver 18 infrared-equipped satellites for tracking ballistic and hypersonic missile threats.

 

Through its Raytheon business, RTX develops radar, sensors and electronic warfare systems that help military forces detect threats and coordinate a response. Its Aurora operation applies those capabilities to space, processing intelligence and planning missions that support everything from navigation to deep-space exploration.

 

BAE Systems builds spacecraft and mission hardware for military and intelligence customers, continuing the legacy of Ball Aerospace after acquiring the Colorado-based company in 2024. Its Space & Mission Systems headquarters in Broomfield anchors three Colorado sites, including a 630,000-square-foot facility, where it develops and tests spacecraft payloads.

 

L3Harris Technologies keeps watch over the space domain with radar, optical sensors and software that help military operators track objects and identify potential threats. At Schriever Space Force Base in Colorado Springs, the company’s teams operate Space Force systems and run live, virtual and constructive training for operators preparing to work with them.
