ABOUT US
Protolaunch is a chemical propulsion and space mobility company developing rocket engines to power the in-space economy.
Continuous deep-throttling engines, ideally suited to:
Kick Stages | In-Orbit Propulsion | Landers
Our patent-pending technology focuses on removing complex turbopumps without sacrificing performance.
Protolaunch operates a dedicated rocket engine test facility within the Westcott Space Cluster with full propellant delivery and data acquisition systems for engines up to 15kN.
Working with partners including the European Space Agency, UK Space Agency, Protolaunch is rapidly bringing our revolutionary new propulsion products to market.

RELIABLE
Additive manufacturing techniques enable reduced part counts, mass savings and flow geometries not possible through conventional methods.

SIMPLE
With few moving parts and vastly lower operating pressures, the reduced complexity of Protolaunch propulsion systems allows for a focus on simplicity.

ENVIRONMENTALLY SUSTAINABLE
Our engines facilitate a shift away from the historic use of Hydrazine to the green propellants of the future.
