Medium-Lift Launch Vehicle Faces Manufacturing Challenges

Rocket Lab has announced another delay for its medium-lift Neutron rocket, citing an issue discovered during manufacturing of the rocket’s carbon composite structures. The company identified a manufacturing defect in the propellant domes at the ends of the rocket’s first stage tanks, which led to a delay in production. Rocket Lab has since modified its manufacturing process and solved the problem, but the delay has pushed the Neutron rocket’s first launch date to 2027. The news was reported by Ars Technica.
