    Rocket Lab delays Neutron launch to 2027 following composite tank defects

    Question

    Rocket Lab delays Neutron launch to 2027 following composite tank defects

    Direct answer

    Rocket Lab disclosed a postponement of its Neutron rocket program into 2027, missing its previous target of the fourth quarter of 2026. The delay stems from structural manufacturing defects discovered in the carbon composite dome of the vehicle's first-stage propellant tank. The setback triggered a 10% share decline to $53, extending its retreat to 65% below its peak recorded in May 2026. The delay extends development spending and defers customer billings for medium-lift orbital deliveries. Market attention shifts to qualification testing for replacement domes and the operating cash cushion provided by ongoing Electron launches.
