We build rockets to launch small satellites.

RS1

RS1 is a resilient launch vehicle purpose-built for the high-cadence, low-cost, no-fuss future of orbital launch. Dirt-simple tank architecture and pressurization systems simplify manufacturing and launch operations. Staged combustion engines provide a time-tested route to high ISP. Metallic structures and proven methods of manufacture minimize technical risk.
RS1 is the rocket you build when you focus on the only true design constraint: it has to work.
