    Rocket Lab Delays Debut Neutron Launch to 2027 Due to Tank Defect

    Question

    Rocket Lab Delays Debut Neutron Launch to 2027 Due to Tank Defect

    Direct answer

    Rocket Lab updated its program schedule for the medium-lift Neutron launch vehicle, deferring the debut launch from late 2026 into 2027. Engineering inspections revealed structural integrity defects in the carbon composite dome of the first-stage propellant tank during manufacturing stress qualification. The delay defers Rocket Lab's entry into the competitive medium-lift constellation deployment market. Capital expenditures dedicated to tooling redesign will prolong negative program cash flow before manifest revenue commences.
