Company Overview

Rocket Lab designs, manufactures, and operates space launch vehicles and related technologies.

Electron has successfully completed numerous commercial missions since its debut, establishing a reliable track record for customers.

Neutron aims to compete with vehicles like SpaceX's Falcon 9 in the medium-lift market segment. The company is expanding its infrastructure with multiple launch sites globally to provide customers with flexible scheduling and diverse orbital inclinations. These developments position RKLB for significant growth as the space industry expands.
