- SpaceX is preparing for an IPO in June, with a valuation estimated above $1.25 trillion
SpaceX has secured a $4.16 billion contract from the U.S. Space Force for a new satellite program designed to detect and track airborne threats.
The U.S. Space Force has just announced that it has awarded @SpaceX a $4.16 billion contract to build a constellation of satellites that can track airplanes, cruise missiles, and airborne threats globally from orbit.

The program is called the Space-Based Advanced Moving Target Indicator, or SB-AMTI. It will use a network of satellites, ground systems, and secure communications to give U.S. military forces better awareness of threats in the air.
What the Satellites Will Do
The satellites are built to detect missiles and other airborne weapons that can bypass traditional detection systems. Adversaries have developed more advanced attack systems in recent years, which is part of what drove the program.
Col. Ryan Frazier, acting Space Force portfolio acquisition executive, said the program gives the military “sustained battlespace awareness of contested airspace.”
The satellite constellation is expected to be deployed by 2028. The Space Force said it will issue more contracts to other companies in the vendor pool over the coming year.
The SB-AMTI program is part of the Trump administration’s Golden Dome missile defense initiative. That program is now estimated to cost $185 billion, up $10 billion from an earlier figure, to speed up space-based capabilities.
SpaceX’s Growing Government Business
This is the second large Space Force contract SpaceX has picked up this week. Earlier, the company was awarded a $2.29 billion deal to build a secure satellite communications network connecting military sensors and weapons platforms around the world.
Together, the two contracts total over $6 billion in new government work for SpaceX in a matter of days.
SpaceX currently earns most of its revenue from Starlink, its satellite internet service. Analysts say the new military contracts help diversify that revenue base.
The contracts come as SpaceX is gearing up for its IPO, expected in June 2026. The company is targeting a valuation of more than $1.25 trillion, which would make it the largest public market debut in history.
The Space Force described the SB-AMTI award as an “initial” contract, with more to follow. Several other companies are also part of the vendor pool for the program.
SpaceX was founded by Elon Musk and has grown into one of the most active contractors for the U.S. government in the space sector.
The Golden Dome program, which the satellites will support, also includes ground-based interceptors, additional sensors, and command systems alongside the space-based layer.
No launch dates for the SB-AMTI satellites have been announced yet. The Space Force said the goal is to have an early operational capability in place by 2028 to close what it called “operational blind spots.”
