    Rocket Lab postpones Neutron inaugural launch to 2027 on tank dome defect

    Question

    Rocket Lab postpones Neutron inaugural launch to 2027 on tank dome defect

    Direct answer

    Rocket Lab announced a schedule delay for its medium-lift Neutron launch vehicle, moving the maiden launch window from the fourth quarter of 2026 into 2027. The shift follows structural flaws identified during manufacturing tests on the first-stage propellant tank's carbon composite dome. The equity fell 10% to $53 on the news, standing 65% below its May peak. While revenue generation from the Electron launch system and spacecraft components business continues uninterrupted, the postponement defers high-capacity commercial satellite constellation launch revenues.
