How many BE-4 engines power the first stage of the New Glenn heavy-lift vehicle?
Answer
Seven BE-4 engines
The New Glenn rocket, classified as a heavy-lift launch vehicle, utilizes substantial propulsion derived from multiple high-thrust engines on its initial stage to achieve orbital velocity. Specifically, the first stage configuration is powered by a cluster of seven BE-4 engines. This powerful arrangement supports the vehicle’s massive size, noted as having a 7-meter diameter. The employment of seven BE-4s provides the necessary thrust margins for deploying significant payloads, including government missions like the ESCAPADE science satellites, into orbit.
