The U.S. Space Force awarded SpaceX a $4.16 billion Other Transaction Authority (OTA) contract, Friday, to accelerate the Space-Based Airborne Moving Target Indicator (SB-AMTI) program, aiming to field an initial satellite constellation by 2028.
The SB-AMTI system integrates space-based sensors, secure communication links, and resilient ground processing to eliminate operational blind spots and provide sustained battlespace awareness in contested airspace.
This initiative is designed to provide persistent, global tracking of airborne threats—such as aircraft, drones, and cruise missiles—from space, addressing vulnerabilities caused by adversary anti-access/area-denial (A2/AD) systems that threaten traditional airborne platforms like the aging E-3 Sentry and the planned E-7 Wedgetail.
SpaceX was selected from a pool of nine companies chosen in April 2026; the Space Force anticipates issuing multiple additional awards in the coming year to expand the industrial base and enhance capacity.
The contract aligns with the Golden Dome missile defense initiative and follows a $2.29 billion SpaceX award for the Space Data Network Backbone announced just days prior, totaling $6.45 billion in Space Force contracts for the company in one week.
The Space Force plans to operate second- and third-generation SB-AMTI systems by 2035, while the Air Force continues to fund the E-7 Wedgetail as Congress blocked earlier cancellation attempts.
“We are beginning development and integration efforts immediately to meet the program’s rapid deployment milestones and address emerging national security requirements,” said Col. Ryan Frazier, acting Space Force portfolio acquisition executive for Space Based Sensing & Targeting. “We will not leverage any one single provider; instead, we are partnering with a highly diversified pool of traditional and non-traditional vendors, each bringing various capabilities to support the SB-AMTI architecture, ensuring the Joint Force has access to a strong, competitive industrial base well into the future.”
