What Happened

Medium-Lift Rocket Debut Pushed Back Due to Manufacturing Flaw

Rocket Lab Corporation has announced a delay in the inaugural launch of its Neutron rocket, pushing the debut from the fourth quarter of 2026 to 2027. The cause of the delay is a manufacturing defect in the forward propellant dome, specifically voids within the carbon-composite layers. A new dome is being built with a refined process and must pass ultrasonic testing before the launch can proceed. This development was first reported by Tech Insider.
