Space Force Bets $397M on Rocket Lab's Untested Neutron Rocket
A $615M second SB-AMTI order splits between Rocket Lab, STR and an undisclosed third vendor, and Rocket Lab's cut rides a rocket that hasn't flown yet.

The U.S. Space Force awarded a second $615 million task order on Aug. 4 for satellites that track aircraft and cruise missiles from orbit, splitting the work between Rocket Lab, Systems & Technology Research (STR) and a third contractor the service declined to identify. Rocket Lab’s disclosed share, $397 million, buys satellites that will fly on Neutron, the company’s medium-lift rocket that has not yet completed a single orbital launch.
What the task order actually buys
The award falls under the Space-Based Airborne Moving Target Indicator program, or SB-AMTI, run by the Space Force’s Portfolio Acquisition Executive for Space-Based Sensing and Targeting. SB-AMTI’s job is narrower than it sounds: track airborne threats, meaning aircraft and cruise-missile-class targets, from low Earth orbit, as a persistent, space-based substitute for the handful of manned early-warning aircraft, like the E-3 Sentry, that the U.S. relies on today. That is a different mission from the ballistic and hypersonic missile-tracking layer the Space Development Agency is building under Golden Dome, a distinction that matters because both efforts moved forward in the same week and are easy to conflate.
Rocket Lab’s contract covers designing, building, launching and operating multiple “Flatellites,” a flat-panel satellite bus the company is optimizing for large constellations, each carrying onboard sensors and low-latency, high-bandwidth communications links. The $397 million figure is not entirely locked-in spending: it bundles firm work with an unexercised option for additional satellites, so the eventual bill could land lower than the headline number if the Space Force never exercises that option.
Betting a payload on an unflown rocket
The notable risk in this deal is the launch vehicle, not the satellites. Rocket Lab built its reputation on Electron, a small launcher that has flown repeatedly from Wallops Island, Virginia, and Mahia, New Zealand, including missions for the National Reconnaissance Office. Neutron is a different animal: a larger, reusable, medium-lift rocket under construction at Launch Complex 3 on Wallops Island that has slipped its debut multiple times and has no confirmed maiden-launch date as of this reporting. Committing a Space Force sensing payload to Neutron before it has flown once is the kind of schedule risk that normally makes military planners nervous, since a launch failure or extended delay would set back the SB-AMTI constellation’s fielding timeline along with it.
That risk is precisely why the Space Force appears comfortable with it. SB-AMTI is explicitly framed as a technology-diversification effort, not a single-architecture commitment, so a schedule slip on one vendor’s launch vehicle degrades the program’s timeline without sinking the whole constellation the way it would if Rocket Lab were the sole supplier. The Space Force gets to find out whether Neutron delivers on a real contract rather than a hypothetical one, and if it doesn’t, the STR and undisclosed third-vendor satellites still fly on other rockets.
“Rocket Lab is honored to play a key role in the SB-AMTI program, which is critical to expanding the Space Force’s layered, resilient tracking architecture,” said Sir Peter Beck, founder and CEO of Rocket Lab, in the company’s Aug. 4, 2026 press release (GlobeNewswire, Aug. 4, 2026).
Diversification is the actual story
The Space Force’s own framing of this task order leans hard on the word “diversification.” Splitting $615 million across three separate contractors, each building satellites with different sensor approaches, is a deliberate hedge against relying on one company’s technology or one company’s supply chain for an entire tracking layer. That instinct traces back to a lesson the Pentagon has learned repeatedly across space programs: a single-vendor architecture is efficient until that vendor slips a schedule or a launch vehicle fails, at which point the whole capability slips with it. Splitting this second SB-AMTI order three ways means a problem at any one contractor, whether it is Neutron’s unproven flight record or a sensor design that underperforms in testing, degrades the constellation rather than deleting it.
It is worth being precise about what this award is not. Three days earlier, on Aug. 3, the Space Force locked in a $1.6 billion NSSL Phase 3 launch-services contract with SpaceX for 18 Falcon 9 missions carrying the Space Development Agency’s Proliferated Warfighter Space Architecture sensing and tracking payloads. That deal used a different acquisition vehicle, a different vendor and a different mission set, missile warning and tracking rather than airborne target indication. The two awards landing in the same week illustrates how much of the Pentagon’s current space spending is flowing into overlapping but distinct sensing layers at once, not a single unified program.

Frequently asked questions
What does SB-AMTI actually track? +
Airborne threats, meaning aircraft, cruise missiles and drones, from orbit in real time, as a persistent alternative to manned airborne early-warning platforms like the E-3 Sentry.
Has Rocket Lab's Neutron rocket ever flown? +
No. As of this reporting, Neutron has not completed a maiden orbital flight, and the company is committing a national-security payload to a vehicle with no flight heritage.
Why split the money between three companies instead of one? +
The Space Force describes this task order as a deliberate vendor-diversification move, testing different sensing approaches from separate contractors rather than depending on a single supplier.
Is this the same as the SpaceX $1.6 billion contract from August 3? +
No. That was a separate NSSL Phase 3 launch-services deal for SDA missile-tracking payloads. This is a different program (SB-AMTI), a different contract vehicle, different vendors and a different mission, tracking aircraft rather than missiles.
