Pentagon awards General Dynamics $400M contract for ground segment of missile-tracking satellites

The U.S. Space Development Agency (SDA)—the Pentagon office responsible for building America’s next generation of missile-tracking satellites—has awarded General Dynamics Mission Systems a contract valued at up to $400,400,000 for the development of the ground segment for Tranche Three of the Proliferated Warfighter Space Architecture (PWSA).

The PWSA is the government’s name for a sprawling network of satellites designed to provide U.S. forces with near-instant warning when an enemy missile launches anywhere on Earth. The ground segment functions as mission control: the software and infrastructure on the ground that communicates with satellites overhead, directs their tracking targets, and delivers data to commanders in seconds rather than hours. Without this ground infrastructure, even the most advanced satellite constellation remains expensive hardware spinning silently in orbit.

Work Locations and Timeline

Work under the contract will be performed across multiple states:

• Scottsdale, Arizona (primary location)
• Seattle, Washington
• Grand Forks, North Dakota — home to one of SDA’s two Space Operations Centers, which already controls Tranche One satellites
• Redstone Arsenal, Alabama — site of SDA’s second operations center and a longtime hub for Army missile programs
• Chantilly, Virginia — where General Dynamics Mission Systems’ space business is based

Completion is expected by September 30, 2030.

Contract Structure and Background

General Dynamics Mission Systems, headquartered in Fairfax, Virginia, is already familiar with the program. The company previously built the ground system foundation for Tranche One and expanded it for Tranche Two under a separate $491.6 million SDA award. This new contract allows the company to extend that same architecture rather than start from scratch.

The SDA structured this latest deal as a sole source acquisition, meaning it was awarded directly to General Dynamics without competition. The agency has consistently defended this approach by citing the technical continuity of building on ground systems the company already operates for earlier satellite batches.

The Proliferated Warfighter Space Architecture

The PWSA represents one of the Pentagon’s most ambitious space investments in decades. It is built around the concept that dozens or hundreds of smaller, cheaper satellites working together are harder for an adversary to disable than a handful of exquisite, expensive ones.

The Tracking Layer—the specific component this contract supports—is responsible for:

• Spotting missile launches from space
• Following those weapons through flight
• Generating what the agency calls fire control quality tracks—tracks precise enough to help missile defense systems intercept an incoming threat, not just warn that one is coming

The SDA has already awarded approximately $3.5 billion in contracts to build 72 Tracking Layer satellites for Tranche Three alone, split among multiple companies each responsible for 18 satellites. Those satellites are expected to launch no earlier than 2029, meaning General Dynamics is essentially building the mission control room years before most of the spacecraft it will manage even reach orbit.

Tranche One Progress

Tranche One alone calls for 154 operational satellites plus four demonstration spacecraft flying at roughly 1,000 kilometers (620 miles) altitude. These satellites will deliver:

• Persistent tactical data links
• Missile tracking and warning
• Beyond-line-of-sight targeting to combatant commands worldwide

The SDA has already launched more than 60 Tranche One data transport satellites and expects the first tranche to deliver initial warfighting capability by 2027, giving U.S. forces a working preview of what the fully built-out system—including Tranche Three—is ultimately meant to provide at much greater scale.

Funding

The SDA has obligated $60,665,380 of the total contract value so far, drawn from fiscal year 2026 research and development funding. The remaining funds will follow as work progresses toward the September 30, 2030 completion date.
