Rocket Lab's SpaceX Challenger Faces a New Curveball
Rocket Lab (RKLB) delayed its Neutron rocket's first flight to 2027 due to manufacturing defects in a carbon-composite component. Shares fell 7.3% in extended trading after a 7.9% drop during the regular session. The issue involves tiny air pockets in the forward tank dome, prompting a manufacturing process adjustment. The company expects to complete the replacement dome before Q1 2027 but did not provide a new launch date.
