Rocket Lab, founded in Auckland, fell 6.64% to US$55.25 on Thursday. After Wednesday's close, it said Neutron, the much bigger rocket it is building to compete with SpaceX's Falcon 9, will not fly until 2027.

**The fault is in a dome.** Rocket Lab found voids, small air pockets, in the carbon-composite dome that caps the first-stage propellant tank. Chief executive Peter Beck said the flaws did not necessarily mean the dome would fail in flight.

He would not take the chance anyway. "Possible success isn't our standard," Beck said. The company now expects to assemble the first stage in the March 2027 quarter and set a launch date after that.

The timetable has slipped before. When Neutron was unveiled in 2021, the target was a first launch in 2024\. That became 2025, then the end of this year.

Thursday's trade was rough. The shares fell as much as 16% to US$49.69 before recovering, after losing 7.85% in Wednesday's session.

The long view 

Beck has chosen a later date over a riskier first flight, and for a rocket company that is a defensible trade. The next marker is the first stage, due to be assembled in early 2027, and every date Neutron has been given so far has slipped.
