Orbit shouldn't cost a fortune.
We shoot cargo into space.

CosmoFlux builds ground-based light-gas gun launchers — reusable artillery for the orbital economy.

Main — The Launch Scarcity Problem

Demand outruns supply

Satellite constellations, orbital stations and in-space manufacturing all need mass in orbit — far more than today's rocket fleets can lift. Launch slots are booked years ahead.

Rockets are mostly fuel

A conventional rocket is ~90% propellant and tanks. You burn an entire vehicle's worth of complexity to deliver a small payload fraction, and every launch consumes costly hardware and range time.

Our answer

Leave the propellant on the ground. A fixed gun launcher delivers rugged bulk cargo — fuel, water, metals, shielding — at high cadence, reserving rockets for people and delicate payloads.

Technology — Light-Gas Gun Launch

How it works

A piston driven by combustion compresses a light gas — hydrogen or helium. Its low molecular weight gives a very high speed of sound, so the expanding gas can push a projectile to several km/s along a long evacuated barrel.

Proven physics

Two-stage light-gas guns routinely reach 6–7 km/s in impact labs. In 1966, Project HARP fired a 180 kg projectile to 180 km altitude with a 16-inch gun — gun launch to space is demonstrated, not hypothetical.

Built for cargo

Acceleration reaches thousands of g, so we launch hardened cargo, not crews. A small onboard kick stage circularizes the orbit after the ballistic ascent.

Why it's cheap

The launcher stays on the ground and is reused thousands of times. Marginal cost per shot is gas, energy and a simple projectile — targeting well under $500/kg to LEO.
