Rocket Lab announced on an after-hours webcast on Oct. 14 that the inaugural launch of its Neutron reusable rocket is being pushed back again, this time out of 2026 and into 2027.

The company did not specify when in 2027 it hopes to fly, and CEO Sir Peter Beck acknowledged that the 2027 target itself is "an ambitious timeline" — an admission, as The Motley Fool notes, that the deadline may itself be missed.

Management had been hoping to get Neutron off the ground before the end of 2026.

The problem arose during manufacturing of the carbon composite "domes" that form the tops and bottoms of the first-stage propellant tanks. Air pockets were forming between the layers of carbon composite laid down to build the domes, weakening their structural integrity.

According to The Motley Fool, the defects would not necessarily cause a failure or an in-flight explosion, but Rocket Lab decided it would not take chances and chose to delay until it could develop a new manufacturing process that prevents the air bubbles from forming.

A delay taken to avoid a first-flight disaster might seem prudent, yet investors sold off the stock on the news, and shares closed last week down 25%, according to The Motley Fool. The frustration is compounded by vagueness: not only is 2027 the new target, but no month or quarter was given.

Kalkine Media reports the stock sits far below both its short-term and long-term moving averages, with the shares at $52.60 after a modest 2.69% rebound on the latest session — relief trading on volume well below a typical day.

Beck told investors "We've solved the problem," saying Rocket Lab has figured out how to stop the air pockets from forming in the composite domes, per The Motley Fool.

He also framed the slower pace as deliberate: Rocket Lab is "building the program's long-term infrastructure at the same time as we build our first rocket, so that we can scale quickly" once the kinks are worked out, and "we won't rush to the pad with unnecessary risk."

No new hardware milestone or launch window has been demonstrated publicly, so the fix remains a management claim, not a flight-proven one.

Neutron is the center of Rocket Lab's valuation because Electron, its small launcher, can only carry small payloads.

Kalkine Media explains that Neutron is designed to lift far heavier payloads and to be reusable, opening access to larger satellite constellations and national security missions in a medium-lift market currently dominated by a single large private competitor.

The delay postpones expected Neutron revenue, extends heavy development spending, and keeps earnings negative — the latest quarter beat revenue forecasts but missed on earnings per share.

Kalkine Media also notes the company carries almost no debt relative to equity, giving it a cushion to absorb the slipped timeline.

Even under the old plan, Rocket Lab anticipated only one Neutron launch in its first year, followed by three the next year and five the year after, so The Motley Fool argues the few extra months — or even a year — will not change near-term revenue much, and Rocket Lab is still expected to earn its first profit next year with or without a Neutron launch.

Meanwhile the proven side of the business keeps performing: Kalkine Media reports another clean Electron mission delivered a trio of satellites for a repeat customer building a radio-frequency mapping constellation, reinforcing the launch cadence that pays the bills while Neutron waits for 2027.
