Pentagon awards General Dynamics $400M contract for ground segment of new 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 ground segment functions as the mission control system: the software and infrastructure on Earth that communicates with satellites overhead, directs their tracking activities, and delivers data to commanders in seconds rather than hours. Without this ground infrastructure, even the most advanced satellite constellation remains "just expensive hardware spinning silently in orbit."

Contract Details

• Awardee: General Dynamics Mission Systems
• Contract Ceiling: $400,400,000
• Type: Sole source acquisition (awarded without competition)
• Completion Date: September 30, 2030
• Funding Obligated to Date: $60,665,380 (from fiscal year 2026 research and development funding)

Work Locations

Work under the contract will be performed across multiple states:

• Scottsdale, Arizona — Primary team 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

Background and Continuity

General Dynamics Mission Systems, headquartered in Fairfax, Virginia, is already a key partner on the PWSA 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 the same architecture rather than develop a new system from scratch.

The SDA structured the award as a sole source acquisition, a decision the agency has consistently defended 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 initiatives in decades. It is built around the concept that dozens or hundreds of smaller, cheaper satellites working together are harder for adversaries to disable than a small number of large, expensive ones.

Tracking Layer

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

• Spotting missile launches from space
• Following those weapons through flight
• Generating "fire control quality tracks" precise enough to enable missile defense systems to intercept incoming threats, rather than merely warn that one is coming

Tranche Three Satellites

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

Tranche One Overview

Tranche One calls for 154 operational satellites plus four demonstration spacecraft flying at approximately 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, providing American forces with a working preview of the fully built-out system—including Tranche Three—at much greater scale.
