Rocket Lab Neutron
Neutron is Rocket Lab's developing reusable medium-lift launch vehicle for constellation deployment, national-security missions, cargo delivery, and deep-space payloads. Its carbon-composite first stage carries the captive 'Hungry Hippo' fairing back to Earth and is designed for return-to-launch-site or downrange landing. Nine methane-fueled Archimedes engines power the first stage and one vacuum Archimedes powers the expendable upper stage.
