Rocket Lab now expects first Neutron launch in 2027
Rocket Lab (NASDAQ: RKLB), a US space company that builds rockets and spacecraft, said on Tuesday, October 14, 2026 that the first launch of its Neutron rocket is now expected to take place in 2027.
What the company said
In a filing with the US Securities and Exchange Commission, Rocket Lab said the timing of the first launch had changed as it continues development and incorporates process improvements. The company said it is progressing through key manufacturing and testing milestones and that it will provide further updates as work continues. The filing did not include any financial figures related to the change.
About Neutron
Neutron is a reusable medium-lift rocket. It is about 43 metres tall and runs on liquid methane and liquid oxygen. Its first stage is designed to return and land after launch, so that it can be flown again, an approach intended to lower the cost of each launch.
Neutron is designed to carry much larger payloads than Electron, the small rocket Rocket Lab has been launching since 2017. This would allow the company to compete for launches of larger satellites and groups of satellites for constellations, as well as government missions. Neutron will launch from Launch Complex 3 at the Mid-Atlantic Regional Spaceport at NASA's Wallops Flight Facility in Virginia.
Earlier timing updates
Neutron was announced in March 2021. The first launch has been moved several times:
- in January 2026, a first-stage tank ruptured during a pressure test, and the first launch moved from mid-2026 to late 2026, according to Spaceflight Now
- in August 2026, the company said the window for a launch in 2026 was narrowing, according to the same report
- on October 14, 2026, the company said the first launch is now expected in 2027
Customers
According to Spaceflight Now, Rocket Lab has more than half a dozen Neutron customers, and Neutron can compete for task orders under the US National Security Space Launch Phase 3 Lane 1 contract. Kepler Communications has booked a dedicated Neutron launch no earlier than 2028.
Why it matters for Rocket Lab
Rocket Lab's business includes launch services and space systems, such as satellites and spacecraft components. Neutron is part of the company's plan to offer launches for larger payloads, a market currently served by a small number of providers. The timing of Neutron's first flight is therefore one of the items investors follow when looking at the company.
Rocket Lab chief executive Peter Beck has described the goal of Neutron's reusability as getting to a high flight rate quickly. Speaking in August, he said "it's really about how do we get to flight ten in the shortest time possible," according to Spaceflight Now.
The steps before a first launch
Before a new rocket flies, its parts are built and tested individually, then assembled and tested together. For Neutron, this includes qualification of the first stage, which carries the main engines and propellant tanks, and integrated static fire testing, in which the engines are fired while the rocket is held down on the pad. According to Spaceflight Now, the integrated tests are planned at Launch Complex 3 in Virginia. In August, Beck described this stage as the one with the highest risk, saying "when it doesn't go well, it really doesn't go well."
What to watch
Key items for the coming months include further development and testing milestones, the arrival of the rocket at the launch pad, integrated testing, and any updates in Rocket Lab's next quarterly results.
Risks and uncertainties
Developing a new rocket involves technical, schedule and cost risks. Launch dates can change as testing continues, and new rockets may not perform as planned on early flights. Space company shares can be volatile.
