Lockheed Martin develops space-based interceptor for missile defense

Lockheed Martin has been selected by U.S. Space Force Space Systems Command to develop capabilities for the Space-Based Interceptor (SBI) program, supporting the expansion of layered missile defense systems.

The program focuses on establishing an early interception layer in space to enhance detection, tracking, and neutralization of emerging missile threats.

Space-based interception architecture
The SBI system is designed to operate as part of a multi-layered defense architecture, enabling interception during earlier phases of a missile’s trajectory. Positioning interceptors in space extends coverage and reduces response time compared to ground- or sea-based systems.

Early engagement capability improves interception probability and contributes to system survivability by distributing defense assets across multiple domains.

Integration with existing missile defense systems
The development builds on existing interceptor technologies, including systems such as THAAD and PAC-3, as well as next-generation interceptor programs. These systems provide the baseline for kinetic interception, guidance, and tracking capabilities.

Integration with missile warning and tracking systems enables coordinated operation across detection, targeting, and engagement layers.

Multi-domain defense capability
The SBI program contributes to a distributed defense framework combining space-based, ground-based, and maritime assets. This approach increases redundancy and resilience against evolving threats, including hypersonic and advanced ballistic missiles.

By adding a space-based layer, the system enhances overall coverage and reduces reliance on single-domain interception.

Development and demonstration timeline
The program includes development, testing, and system integration activities leading toward a planned demonstration of integrated capabilities by 2028.

The phased approach allows validation of system performance, interoperability, and operational concepts prior to full deployment.

Role in future missile defense systems
The SBI capability is intended to strengthen homeland and infrastructure protection by expanding interception options and improving system responsiveness.

Through its development efforts, Lockheed Martin contributes to advancing integrated air and missile defense systems that address emerging threat environments.
