Rocket Lab postpones debut of its medium-lift Neutron vehicle until 2027

Rocket Lab has postponed the inaugural flight of its medium-lift Neutron rocket to 2027 following production setbacks. The launcher, designed to haul up to 13,000 kilograms into low Earth orbit, had previously been eyed for delivery to its launch pad at Wallops Island, Virginia, before the end of this year. [1][2]

The delay stems from carbon composite manufacturing challenges on the reusable first-stage booster. Chief executive Peter Beck revealed that voids formed between layers during fabrication of a propellant dome, diminishing safety margins. While Beck stated the flaw has now been solved, cryogenic and hydrostatic testing will not wrap up until the first quarter of 2027, after which the company will set a formal launch date. [1][2]

Investor reaction was swift, with Rocket Lab shares falling from around $63 to near $53 in after-hours trading. The company hopes Neutron will eventually compete directly with SpaceX's Falcon 9 class of launchers, featuring a fully reusable booster and an integrated clamshell fairing that captures and returns the stage to Earth.
