Rocket Lab Electron Reaches 100 With iQPS Satellite

Rocket Lab has flown its 100th Electron mission, sending a radar-imaging satellite into low Earth orbit for a Japanese customer. In a 14 November 2026 update, the company said the mission, named “The Mountain God Rises,” lifted off from Launch Complex 1 in New Zealand at 6:30 p.m. on 14 November and deployed the YAMATSUMI-II synthetic aperture radar satellite “to a 575km low Earth orbit” for the Institute for Q-shu Pioneers of Space (iQPS).

iQPS, in its own 14 November notice, timed the same liftoff at 02:30 p.m. Japan Standard Time, which is 05:30 GMT, and said the satellite was deployed into its planned orbit approximately 50 minutes later. Those two official clocks describe one launch. Rocket Lab also presents the flight as a company milestone: it says Electron has set “a new record for reaching 100 launches faster than any other commercially developed rocket.” That ranking is Rocket Lab’s claim. No independent league table is cited in the release.

YAMATSUMI-II reached a 575 km orbit, and iQPS later confirmed its antenna

iQPS identifies the payload as QPS-SAR-19, named YAMATSUMI-II. After deployment, it said the first communication was established around eight minutes later, and that “all the satellite’s equipment was working properly” and the spacecraft was “in good health.” At that point the company was still planning to deploy the antenna and to acquire first images.

A follow-up iQPS notice, also dated 14 November, said the satellite “successfully deployed its parabolic antenna this evening.” It added that the team was “currently preparing to obtain the first Earth observation data after completing its scheduled calibration.” The antenna, then, is reported as open. The first radar images are not yet in hand, on iQPS’s own wording.

The flight was not a one-off booking. Rocket Lab said the mission was its “11th Electron launch for iQPS with 100% mission success since 2023,” and that iQPS “has booked seven more dedicated Electron launches through 2030 to complete its satellite constellation.” The 100 per cent success line, and the reserved future flights, are the company’s account of that customer campaign.

Rocket Lab says Electron reached 100 launches faster than any other commercial rocket

The 14 November release is dated Long Beach, California, and is explicit about the record it is claiming. “Reaching 100 launches in under a decade is a major milestone for commercial spaceflight,” it says, tying the count to a first launch in 2017 and to pads in New Zealand and Virginia. Founder and chief executive Sir Peter Beck is quoted as saying: “Not only has Electron now reached 100 launches, but it reached the milestone faster than any other commercially developed rocket.” He also said: “The next 100 Electrons are already booked so we’re only accelerating from here.”

Those are statements of backlog and speed, not an audited comparison with every other small-lift vehicle. They should be read as Rocket Lab’s description of its own manifest. The same update says Electron is “laying the operational foundation for Rocket Lab’s next medium-lift rocket, Neutron.” That next vehicle is still in the future. TSN has already reported Rocket Lab moving Neutron’s first launch to 2027 after a tank-dome flaw, and has set out what Neutron is meant to be, and that it has not yet flown.

Rocket Lab also builds spacecraft as well as launching them. TSN’s recent account of the ESCAPADE Mars twins noted Rocket Lab among the mission’s builders, a reminder that the company’s 100th Electron flight sits inside a wider space-systems business, not only a small-rocket cadence story.

A 100th Electron flight is a cadence result, not a Neutron debut

A hundred flights is a real operational number, and it is a different kind of result from a new rocket’s first hop. Electron is a small-lift vehicle that, on Rocket Lab’s telling, has been flying since 2017 and has now reached a round count that many designs never see. That is worth recording as a launch-services fact. It does not, by itself, tell readers anything new about Neutron’s timetable. The company’s own wording places Neutron still ahead, as a medium-lift rocket for which Electron is “laying the operational foundation.” The 2027 first-launch date, and the tank-dome problem that pushed it there, remain the last official TSN record on that vehicle.

The “fastest commercially developed rocket” line should stay inside that frame. Rocket Lab is entitled to make the claim, and Beck repeats it in the same release. TSN has not seen an independent ranking that tests it against other commercial vehicles, and the release does not supply one. The safer reading is the one the company can actually show: a 100th mission from Launch Complex 1, a customer satellite in a 575 km orbit, and a stated booking of seven more dedicated iQPS flights through 2030.

Even that customer story still has an open end. iQPS has confirmed first contact, a healthy spacecraft and a deployed parabolic antenna. It has not yet said it has taken the first radar image. Calibration, on its own notice, still stands between the launch and useful Earth-observation data. The next official facts worth waiting for are those first images, and any later notice that turns the seven booked flights into dated missions. Until then, the story is a 100th Electron, a Japanese SAR satellite on its way to work, and a company record that remains a company claim.
