Rocket Lab wins $90 million Space Force deal

Rocket Lab said on May 21 that it has won a $90 million contract from the U.S. Space Force’s Space Systems Command to design, manufacture, integrate and operate two geostationary satellites carrying the Heimdall space domain awareness payload. The company said the award is its first satellite production program for geostationary orbit and extends its work for U.S. national security customers into a new orbital regime. The contract covers spacecraft production, payload integration, launch integration on a government-furnished launch vehicle and on-orbit operations for as long as five years after commissioning. ### What exactly did Rocket Lab win? The $90 million award is for two geostationary, or GEO, satellites that will host the Heimdall optical payload for the Space Force. Rocket Lab said it will act as prime contractor and end-to-end mission provider, handling spacecraft design and manufacture, integration of the payload, launch integration and post-launch operations. (markets.businessinsider.com) SpaceNews reported that the satellites will be used by the military to monitor and track objects in orbit. That mission falls under what the Space Force calls space domain awareness, the effort to detect, identify and keep custody of objects and activity in space. ### Why does geostationary orbit matter here? (markets.businessinsider.com) Space Systems Command has said sensors in geosynchronous orbit provide a wide field of view and continuous coverage of a region. A prior Space Systems Command explainer said GEO satellites orbit about 22,236 miles above the equator and move in sync with Earth’s rotation, making them useful for persistent observation. (spacenews.com) Rocket Lab said the two spacecraft will carry Heimdall payloads intended to augment the Space Force’s ability to maintain custody of objects in the GEO belt. In practice, that means the satellites are meant to watch other satellites and objects in the same orbital neighborhood used by many military, intelligence, weather and communications spacecraft.

Rocket Lab said the contract builds on an earlier Space Systems Command program that began with prototype development of two Heimdall payloads originally awarded to GEOST. Rocket Lab acquired GEOST in 2025 and folded it into Rocket Lab Optical Systems, according to the company’s release. (markets.businessinsider.com) The new award moves that work from payload prototyping to operational space vehicle delivery, Rocket Lab said. The company described Heimdall as a small, low-cost electro-optical sensor designed to be hosted on satellites in geosynchronous orbit.

Rocket Lab said the satellites will be built on its Lightning spacecraft bus, modified for GEO requirements including thermal control, radiation tolerance, propulsion and station-keeping. The company said Lightning is already in production for other national security and commercial programs, including Space Development Agency work. (markets.businessinsider.com) The company also said it will assemble, integrate and test the satellites at its Spacecraft Production Complex in Long Beach, California. Payload delivery will come from Rocket Lab Optical Systems, and mission operations will be run from Rocket Lab facilities after launch.

On May 7, the company said it had been selected with Raytheon to demonstrate capabilities for the Space Force’s Space Based Interceptor Program, and the same day it announced a separate multi-launch deal covering Neutron and Electron missions for a confidential customer. (markets.businessinsider.com) In December 2025, Rocket Lab announced an $816 million prime contract to build a missile-defense satellite constellation for the U.S. Space Force. The new GEO award is much smaller, but it adds a different mission set and a different orbit to the company’s national security work. (investors.rocketlabcorp.com) ### What happens next? Rocket Lab said the next steps are spacecraft assembly, payload integration and launch integration ahead of flight on a government-furnished launch vehicle. The company did not announce a launch date in its May 21 release, but said on-orbit operations could continue for up to five years after the satellites are commissioned.
