Rocket Lab has signed a multi-year agreement for 20 new Electron missions with Tokyo-based Earth observation company Synspective, the largest commercial launch contract for Electron in the company’s history. The deal brings the total number of Electron missions booked for Synspective to 47, the most of any Rocket Lab customer; the remaining terms were not disclosed. Rocket Lab will launch 20 StriX synthetic aperture radar satellites to sun-synchronous orbit from Launch Complex 1, with missions scheduled annually from 2028 through 2031 as Synspective works toward a constellation capable of imaging any location on Earth within hours, day or night and in any weather.

“When constellation builders want control over their destiny, they come to Rocket Lab. Synspective was one of Electron’s earliest customers, and together we have proven that tailored, dedicated launch is the fastest and most reliable path to scaling small satellite constellations. Signing twenty launches in a single deal is a massive vote of confidence not just in Electron, but in the launch cadence, mission reliability, and orbital precision that Rocket Lab consistently delivers,” said Sir Peter Beck, Rocket Lab founder and CEO.

“Electron’s precision and reliability have played a central role in steadily scaling our StriX constellation. Through this process, our partnership has grown into something built not only on technical progress but on a deep, team-level trust between us … Securing another 20 dedicated launches now gives us long-term certainty for our constellation expansion, a powerful booster toward building the infrastructure needed for a resilient future,” said Dr Motoyuki Arai, Synspective founder and CEO. The agreement is the latest in a run of multi-launch contracts awarded to Rocket Lab this year, which the company says has pushed its launch backlog beyond 100 missions.
