Rocket Lab Delays First Flight of Neutron Rocket to 2027
By Drooid · · How we work
Launch Schedule Revised
Rocket Lab announced that the inaugural launch of its next-generation Neutron rocket has been moved from late 2026 to sometime in 2027. The postponement follows the discovery of voids inside the carbon-fiber propellant dome of the vehicle’s first stage during routine inspection. The company will rebuild the forward dome, complete curing and inspection, integrate it into a full first stage, and then conduct a series of qualification tests before setting a new launch date.
Background & Context
Neutron, a 141-foot-tall (42 m) partially reusable launch vehicle, was first unveiled in 2021 with an initial target debut in 2024. The schedule has been revised repeatedly—to 2025, early 2026, and late 2026—after earlier setbacks, including a fuel-tank rupture during a pressure test. The rocket is intended to complement Rocket Lab’s smaller Electron launcher and to serve larger payloads for commercial and government customers.
Official Statements & Responses
Founder and CEO Peter Beck explained that the company’s automated fiber-placement machine, which creates the carbon-fiber domes, produced a forward dome with internal voids. Rocket Lab’s policy is to proceed only when safety margins are assured. Beck emphasized that the delay is a deliberate choice to ensure reliability, noting strong market demand and upcoming contracts that depend on a dependable launch system.
Data & Statistics
- Neutron height: 141 ft (42 m)
- Propellant: liquid oxygen and liquid methane
- First-stage reusability: designed for recovery and refurbishment
- Timeline milestones: forward dome rebuild and inspection expected by year-end; full first-stage integration and testing slated for the first quarter of 2027.
