Vaxon says it has ground-tested its compressible-flow inlet and propulsion system at the University of Colorado Boulder's Laboratory for Atmospheric and Space Physics.Vaxon Space
- Regulatory status
The company says its air-breathing propulsion proposal was made awardable on DARPA's Expedited Research Innovation System marketplace on 29 October 2025, which it describes as a procurement pathway for Defense Department activities to select and award technologies. That is a route to an award, not an award.Vaxon Space
