Vehicles

Globally, Efficiently, andIndependently

Dedicated orbital access for smallsats worldwide from Latin America's first commercial launch system.

We design, manufacture and operate reusable launch vehicles from Patagonia, Argentina. Space access for small payloads, at weekly cadence, with instrument-grade precision.

Prototype

Kaiken launch vehicles

Patented propulsion system delivering efficiency and reduced mass ratio.
All key fuels and oxidizers sourced locally, minimizing costs and risk.
Launch system optimized for flexible payload integration and simplified ground logistics.

Technology

The Crux fleet

From small-sat deployers to heavy-lift and our Kaiken demonstrator — the full Crux vehicle family.
