Space-Based Missile Tracking Satellite Deployment

L3Harris Technologies is working with the U.S. Space Force's Space Development Agency (SDA) to develop and manufacture 18 Accelerated Missile Defense Tranche 3 (AMDT3) satellites for the Golden Dome for America initiative. The cooperation focuses on expanding space-based missile tracking capabilities to support missile defense operations against hypersonic and ballistic threats within the defense and aerospace sectors.

Cooperation Framework and Industrial Objectives
The collaboration combines the procurement and program management responsibilities of the Space Development Agency with L3Harris Technologies' expertise in satellite engineering, payload integration and space manufacturing. The program addresses the need for persistent space-based sensing capable of detecting, tracking and supporting engagement of advanced missile threats.

The cooperation enables the deployment of a larger constellation of tracking satellites than would be achievable through individual development efforts. Government oversight defines operational requirements, while the industrial partner is responsible for spacecraft production, payload integration, testing and delivery.

Technical Architecture and Partner Responsibilities
The AMDT3 satellites incorporate medium-field-of-view infrared payloads designed to generate fire-control-quality tracking data for missile defense systems. These sensors provide continuous observation of missile trajectories, enabling data to be transferred to command-and-control networks that support interception decisions.

L3Harris Technologies is responsible for spacecraft manufacturing, sensor integration, system verification and production readiness. The Space Development Agency oversees constellation architecture, acquisition and integration into the broader space-based missile defense network supporting the Golden Dome initiative.

The program builds upon technologies demonstrated through the Hypersonic and Ballistic Tracking Space Sensor (HBTSS) program developed for the U.S. Missile Defense Agency, allowing previously validated sensor technologies to be incorporated into operational satellite constellations.

Deployment and Industrial Implementation
Satellite manufacturing will take place at L3Harris' expanded production facility in Indiana, while spacecraft integration activities will be performed at the company's satellite integration facility in Florida. The expanded manufacturing infrastructure is intended to support production capacity for multiple satellite programs and reduce preparation time before launch.

The AMDT3 satellites will join the existing SDA Tracking Layer architecture, complementing satellites already deployed or ordered under Tranche 0, Tranche 1, Tranche 2 and Tranche 3 programs. This phased deployment supports the gradual expansion of the overall digital infrastructure used for missile warning and tracking.

Applications and Operational Use Cases
The satellite constellation is intended for military missile warning, missile tracking and fire-control support applications. By providing continuous infrared observation from orbit, the system enhances the ability to monitor hypersonic and ballistic missile launches across wide geographic areas.

Integration with existing space-based tracking assets improves sensor coverage, increases tracking persistence and supports interoperability with ground-based and airborne missile defense systems.

Program Scale and Expected Impact
The contract covers production of 18 AMDT3 satellites. Including previous awards under the Missile Defense Agency's HBTSS program and the SDA Tracking Layer, L3Harris Technologies has more than 70 missile tracking and defense satellites on order, with five satellites already operating in orbit. The expanded constellation is expected to increase sensor capacity and improve the resilience of space-based missile tracking through distributed satellite architecture.
