Neutron is a medium-lift two-stage launch vehicle under development by Rocket Lab. Announced on 1 March 2021, the vehicle is being designed to be capable of delivering an 8,000 kg (17,600 lb) payload to low Earth orbit, and will focus on the growing megaconstellation satellite delivery market.[2] The vehicle is expected to be operational sometime in 2024.[1] It uses LOX and kerosene propellant.[2]


The rocket is expected to be 40 m (130 ft) tall with a 4.5 m (15 ft)-diameter payload fairing. Rocket Lab have said they are going to aim to make the first stage of the vehicle reusable with landings planned on a floating landing platform downrange in the Atlantic Ocean.[2][3]


Neutron is designed to launch up to 8,000 kg (17,600 lb) of payload to a 400 km (250 mi) low Earth orbit. Rocket Lab also intends the design to be able to eventually support human spaceflight. [3]

Launch site

Neutron is expected to launch from the Mid-Atlantic Regional Spaceport (MARS) on the eastern coast of Virginia, at Launch Pad 0A.[4] The company is evaluating locations across the United States to build a factory to manufacture the new rocket. As of March 2021, Rocket Lab is planning for the first launch to take place no earlier than 2024.[2]
