    Rocket Lab Delays Neutron Maiden Launch to 2027 on Tank Defect

    Question

    Rocket Lab Delays Neutron Maiden Launch to 2027 on Tank Defect

    Direct answer

    Rocket Lab announced a schedule revision for its medium-lift Neutron vehicle, delaying the target maiden launch from Q4 2026 into 2027. The postponement follows the identification of structural manufacturing flaws within the carbon composite dome of the first-stage propellant tank during stress testing. The schedule slippage immediately pressured equity valuation, triggering a 10% intraday decline to $53 per share and extending the equity drawdown to 65% off its May all-time peak. The capital-intensive transition to medium-lift operations faces higher cumulative development expenditures prior to first orbital revenue.
