PhaseFour In the News
Phase Four is a disruptive provider of next generation electric propulsion (EP) solutions for small satellites. The company was founded in 2015 to address the demands of the rapid proliferation of satellite constellations and to accelerate the advancement of its radio-frequency thruster (RFT). The Phase Four RFT represents a revolutionary new architecture that realizes lower cost, mass-manufacturability, miniaturized power electronics, and propellant agnosticism over incumbent technologies, without compromising performance. In 2021 Phase Four’s Maxwell turn-key propulsion system achieved flight heritage and is now being regularly utilized by small satellite operators. For media/press inquiries, contact us.
Phase Four is building out a new 23,000 sq.ft. production facility to support high volume plasma propulsion engine manufacturing.
El Segundo-based Phase Four today finalized a lease to build a second factory and scale production of its Maxwell engine product line. The new Hawthorne facility will be over 3X larger than Phase Four’s current plant, and capable of cranking out 100 engines a year.
For most of the last decade, the U.S. relied almost entirely on Russia for rocket engines and crewed launches into space.
Phase Four expands its leadership team to support the company’s rapid growth in both the commercial and government markets.
