Launch Window Narrows As Development Continues For Medium-Lift Vehicle

Rocket Lab’s anticipated debut of its medium-lift Neutron rocket may end up slipping beyond this year and into 2027, as the company works through various qualification testing and development milestones. The Neutron rocket, announced in March 2021, is designed with a reusable first stage booster and is expected to compete for task orders in the defense sector and commercial launches. According to Spaceflight Now, the company is balancing the schedule of the first launch with entering Neutron into service as a system ready for full-scale production and high-cadence launch beyond flight one.
