Rocket Lab\u2019s anticipated debut of its medium-lift Neutron rocket may end up slipping beyond this year and into 2027.<\/p>\n

In a filing to the U.S. Securities and Exchange Commission (SES) ahead of is second quarter 2026 earnings call with investors on Tuesday, the company noted that it\u2019s working through various qualification testing and made \u201csignificant milestones across the Neutron program.\u201d<\/p>\n

\u201cProduction of the Stage 1 tank is currently aligned with the target delivery of Neutron to the launch pad in Q4 2026,\u201d the company wrote in its filing. \u201cWhile the window for an end-of-year launch date is narrowing, we are balancing the schedule of the first launch with entering Neutron into service as a system ready for full-scale production and high-cadence launch beyond flight one.<\/p>\n

\u201cExact launch timing will also depend on the outcome of first stage qualification and other critical tests occurring later in 2026.\u201d<\/p>\n

Rocket Lab\u2019s Neutron rocket, a 43-meter-tall (141 ft.), liquid methane-fueled launch vehicle, was announced back in March 2021 and has been in development ever since. It\u2019s designed with a reusable first stage booster that features actuating payload fairing halves that remain fixed to the booster after the second stage and payload are released.<\/p>\n

Back on Jan. 21, the company\u2019s first stage fuel tank ruptured unexpectedly during a water loading test called a \u201chydrostatic pressure trial.\u201d That setback pushed the planned debut from the middle of the year to late 2026.<\/p>\n

During Monday\u2019s earnings call, Rocket Lab founder and CEO Peter Beck said the ability to reuse its rockets will be the x-factor that can unlock good launch cadence.<\/p>\n

\u201cAs we\u2019re working forward with the vehicle right now, and the way we\u2019re thinking about things, it\u2019s not just to get to the pad quickly for flight one. Of course we all want that and no one more than I, but it\u2019s really about how do we get to flight ten in the shortest time possible,\u201d Beck said.<\/p>\n

\u201cSo for us, it\u2019s all about reusability. And we\u2019re constantly trading the timelines and the qualification criteria for the various systems and subsystems to get to the pad for flight one, but also making sure that when it comes to flight ten, that we don\u2019t have to go back and re-qualify things,\u201d he added. \u201cSo there\u2019s a constant assessment along that way.\u201d<\/p>\n

Asked about the milestone with the highest risk on the road to Neutron\u2019s debut, Beck said it would be the integrated static fire testing that will happen at the launch pad in Virginia.<\/p>\n

\u201cThe stage testing is always the thing that gets your adrenaline running because you have fully fueled vehicles on the pad and you\u2019re igniting the engines for the first time. And I think you can also see for another space company that when it doesn\u2019t go well, it really doesn\u2019t go well,\u201d Beck said, making a nod to the explosion of Blue Origin\u2019s New Glenn rocket during a static fire test on May 28 prior to its fourth planned launch.<\/p>\n

Awaiting their ride<\/h4>\n

The future for Neutron launches includes the defense sector, where Rocket Lab holds a $397 million contract for building and launching satellites for the U.S. Space Force\u2019s (USSF) Space-Based Airborne Moving Target Indicator (SB-AMTI) program. Launch dates for this program haven\u2019t been announced.<\/p>\n

Neutron will also be able to compete for task orders as part of the National Security Space Launch Phase 3 Lane 1 procurement contract, managed by the USSF\u2019s Space Systems Command.<\/p>\n

On the commercial side of the ledger, Rocket Lab also has more than half a dozen customers lined up for flights on the rocket. The newest of those is Kepler Communications, based in Toronto, Canada.<\/p>\n

Neutron has been selected for a dedicated launch by @KeplerComms as part of their largest network expansion yet \u2013 the first time Kepler has booked an entire rocket for constellation deployment rather than fly rideshare.<\/p>\n
