Boom Supersonic is opening a new facility at the Colorado Air and Space Port to support ground tests of the Symphony engine it is developing for its planned Overture supersonic airliner.

Announcing the site selection on April 25, Boom said it would invest up to $5 million in the new facility this year to support testing of the Symphony’s prototype core—a 12-foot-long fixture containing the supersonic engine’s compressor, combustor, and turbine. In 2026, Boom aims to expand the facility to support full-scale tests of the medium-bypass turbofan engine.
