Supersonic Manufacturer Selects Colorado Air and Space Port for Testing

Boom Supersonic, manufacturer of the XB-1 jet, recently announced that it would be using the Colorado Air and Space Port (CASP) to test its Symphony engine. The $3-5 million test facility will allow Boom to develop a sound propulsion system for its upcoming supersonic airliner, the Overture.

“This is an exciting moment not just for Adams County but for the future of aerospace innovation in Colorado,” expressed Lynn Baca, Chair of the Adams County Board of Commissioners. “Boom’s investment in our community puts us at the forefront of the aerospace industry and reflects our shared commitment to advancing next-generation transportation technologies.”

The manufacturer has been on top of its game this past year, recently completing a full test cycle of its first supersonic design: the XB-1. The aircraft, also nicknamed “Baby Boom,” is a one-third-scale, piloted technology demonstrator for the Overture. It set out to test new materials and tech needed for supersonic flight, and it succeeded by passing Mach 1 for the first time on January 28, 2025.

With a proven design under its belt, Boom Supersonic is ready to advance to the next level by setting up a testing site for its prototype engine core, the Symphony. Construction for the new $3-5 million facility will begin later this year.

The site will re-purpose an old hypersonic test facility at CASP, located just over 30 miles from Boom Supersonic’s headquarters in Denver. It will house advanced instrumentation and data collection systems to streamline and perfect the testing process for Symphony.

“Symphony is rapidly advancing from concept to reality. By leveraging an existing site, Boom will have the first independently-owned supersonic engine test facility for less than it would have cost to rent a government facility,” explained Blake Scholl, Founder and CEO of Boom Supersonic.

Once the 12-foot-long Symphony Engine core moves through testing, Boom will be able to begin developing its full-scale Symphony turbofan for Overture. This advancement is slated for 2026.
