Neutron is a partially reusable medium-lift two-stage launch vehicle under development by Rocket Lab. Announced on 1 March 2021, the vehicle is designed to be capable of delivering a payload of 13,000 kg (28,700 lb) to low Earth orbit in a partially reusable configuration,[3] and will focus on the growing megaconstellation satellite delivery market.[4] The vehicle is expected to be operational sometime in 2025.[3][5] It uses LOX and liquid methane propellant on both stages of the vehicle.[4]
