EMPOWERED BY MANUFACTURING


Performance leading propulsion systems, scaled to meet the needs of the future space industry.

Learn More
_ 01

Simple


Designed from the offset to offer both market leading performance and integration simplicity, enabled through cutting-edge technologies and vertically integrated design, fabrication and test facilities.

_ 02

Scalable


Our unique approach to fabrication inherently enables large-batch sizes and fully scalable production, enabling capital-efficient development and testing as well as dramatically reduced thruster unit cost.

_ 03

Sustainable


Our propellant choices of hydrogen and oxygen not only offer leading performance but are also zero-carbon and non-toxic.

Pioneering 2D+ Fabrication


Precision Etching


  • Micron level feature size and precision enabled through sheet-based fabrication.
  • Identical time and captial cost regardless of sheet feature complexity.
...
...

Sheet Stacking


  • 3D system profile emerges from sheet stacking.
  • Complex, fully enclosed cooling circuits.
  • Exceptionally low hot side wall thicknesses achievable.


Sheet Bonding


  • Diffusion bonding enables a fully homogenous system architecture.
  • Exceptionally high bond strength at near parent material properties.
  • Material agnostic, able to incorporate the most advanced alloys.
