About
Henderson, Nevada startup 3D-printing lightweight engines that use air augmentation to squeeze more thrust and efficiency out of each kilogram of propellant.
4th Planet Propulsion develops air-augmented rocket engines for the aerospace sector. The company utilizes metal 3D printing to manufacture lightweight propulsion systems that draw in atmospheric air to increase exhaust mass during atmospheric flight. This air-augmentation acts similarly to a ramjet, significantly improving the thrust and specific impulse of the engine without requiring the vehicle to carry additional heavy liquid oxygen.
By extracting greater efficiency from its propellant, the company aims to lower the cost of placing small payloads into orbit. Founded in 2024, the startup is headquartered in Henderson, Nevada.
