Where we're building,
testing and launching Neutron.
Archimedes Engine Test Complex
The Archimedes Test Complex is the location for testing of Neutron's reusable Archimedes engine, located at NASA’s Stennis Space Center in Mississippi.
Engine Development Complex
Rocket Lab's Engine Development Complex is located in Long Beach, California. The 144,000+ square foot site supports the development and production of the Archimedes engine for Neutron, as well as the high-rate production of Rocket Lab's Rutherford engine for its Electron launch vehicle.
Launch Site
Rocket Lab Launch Complex 3 is the dedicated launch site for Neutron. It’s located at the Mid-Atlantic Regional Spaceport within NASA’s Wallops Flight Facility on Virginia’s Eastern Shore. Neutron’s pad is adjacent to the existing Rocket Lab Launch Complex 2, the U.S. launch site for Electron. As a reusable rocket, Neutron’s first stage can support return to launch site and downrange landing options, before return to Launch Complex 3 for refurbishment and reflight.
Neutron Assembly & Integration Complex
Located within the Mid-Atlantic Regional Spaceport on Virginia’s Eastern Shore, the Assembly & Integration Complex for the Neutron rocket is where Neutron will take shape before making its way to the launch site on Wallops Island, Virginia. Neutron first stages that return to Earth after launch will also be transported to and housed within the Assembly and Integration Complex to be readied for continued flight operations.
Space Structures Complex
Rocket Lab's Space Structures Complex in Middle River, Maryland, supports the automated production of all large composite structures of the Neutron launch vehicle including the panels that make up the 91 ft (28 meter) length interstage and fairing, 22.9 ft (7 meter) diameter first stage, and the 16.4 ft (5 meter) diameter second stage tank. The site is home to the world's largest AFP machine of its kind, a 90-tonne autonomous machine expected to save around 150,000 manufacturing hours in the Neutron rocket's production process.
