What We're Doing

Phase Four is developing a new paradigm of in-space propulsion for the rapidly expanding space economy. From large constellations in LEO to new missions and cutting edge capabilities, our team is the key to mission success. We are focused, innovative and passionate about space. And above all else, we work together to get the job done.

Production Approach

Phase Four’s Maxwell RF thruster does not implement cathodes anywhere in the system. This eliminates the choke point slowing down manufacturing of traditional plasma propulsion systems.

At Phase Four, we build propulsion systems in runs on a planned production schedule. This allows customers to sign up for units as long as the production run has not commenced, reducing lead times to as short as 3-4 months. We aim for 3-4 production runs per year and each run is comprised of assembly, checkout, and acceptance testing. Take a look at our production schedule below to plan ordering your next Maxwell propulsion system.
