Golden Dome: Defending through Innovation and Integration
A Mission of Unparalleled Complexity
Golden Dome is a bold initiative to build the next-generation missile defense architecture for the United States—an adaptable, resilient shield against hypersonic, ballistic, cruise missiles and advanced threats. Envisioned under a national policy that prioritizes the security of the homeland, this mission unites the efforts of the Missile Defense Agency (MDA), the Space Force, and other organizations in the Department of Defense and the Intelligence Community in pursuit of a multi-domain, multi-layered solution.
This initiative demands close coordination among multiple agencies and technologies, including:
- Hypersonic and Ballistic Tracking Space Sensor (HBTSS)
- Space-Based Interceptors (SBI)
- Proliferated Warfighter Space Architecture (PWSA)
These efforts represent the front lines of our national defense strategy—one that Amentum is uniquely positioned to support and advance.
Amentum: Mission-Proven, Adaptable Ground Layer for Golden Dome
At the heart of any space-based missile defense system is a robust, secure, and scalable ground segment. Amentum has delivered just that—a modular, multi-mission enterprise ground architecture called the Common Ground – Space Enterprise Architecture (CG-SEA).
CG-SEA is a proven capability that supports the three space Lines of Effort (LoEs) under Golden Dome—HBTSS, SBI, and PWSA—and currently supports mission operations for MDA’s HBTSS and Space Based Kill Assessment (SKA) program. Amentum’s architecture is mission-proven, adaptable, and ready to support future space programs at speed and scale.
CG-SEA: A Proven, Scalable Solution
CG-SEA is designed as a modular, technology-agnostic system built from three core elements:
- Platform-as-a-Service (PaaS): High-performance computing, storage, networking, and software pipeline services. PaaS hosts the Ground System Mission Suites and can also support other applications like command and control, battle management, and AI/ML.
- Ground System Mission Suites: Providing tracking, telemetry, command (TT&C); mission monitoring; alerting; and mission-unique software. Proven to provide enterprise services for separate satellite manufacturers.
- Multi-Mission Operations Centers: 24/7 support with integrated infrastructure and scalable systems tailored to mission requirements. Proven to provide integration and testing, launch, RDT&E, and operations for multiple space systems simultaneously.
Through this architecture, Amentum has delivered a cost-effective, multi-threat, multi-contractor, multi-mission ground layer that integrates seamlessly with other mission protection systems and services.
Why Amentum?
Proven Integration and Delivery at Scale
Amentum has decades of experience leading complex integration efforts across the defense and space domains. Across multiple contracts, we support:
- MDA enterprise architecture design
- Critical national missions
- Defense and other government agencies
- Cross-agency coordination and technology deployment
- Operating and maintaining the Integrated Tactical Warning/Attack Assessment (ITW/AA)
- Real-time decisions to respond and defend against hypersonic and hyper-glide threats
We are prepared to extend this expertise to the Golden Dome program, serving as a critical lead integrator—coordinating across government agencies and industry partners.
A Record of Mission-Ready Innovation
Our capabilities span advanced software integration, cyber-hardened infrastructure, and high-assurance AI/ML for mission-critical decisions. Our CG-SEA architecture offers:
- Ground segment ownership independent of satellite providers
- Integration of multi-contractor systems
- Cloud-native, hybrid, or physical deployment flexibility
- Reference Architecture and MBSE-driven time-to-launch optimization
- Multi-classification readiness (IL5–IL7)
- Rapid scalability and enhanced cyber resilience
The Road Ahead
We recognize the strategic challenges still unfolding:
- Determining roles, responsibilities, and acquisition authorities
- Understanding how offerings from other primes align or compete
- Clarifying integration roles across the Golden Dome enterprise
That’s why Amentum is actively building the relationships and positioning necessary to accelerate Golden Dome delivery—and ensure the most adaptable, resilient systems are brought to bear for national defense.
