Digital Engineering from the Ground Up

Ushering The Nation’s Strategic Deterrent into the Digital Age

By Presley Price

For more than 70 years, the U.S. Nuclear Triad has been a source of global stability, deterring adversaries, limiting conflict escalation and assuring allies. While the land-based intercontinental ballistic missile (ICBM) is critical to the Nuclear Triad, providing the most responsive capability, the current system is aging out and must be modernized to maintain strategic stability.

Modernization of an existing ICBM system at this scale has never been done before, and the complexities of transitioning a program of this size from analog to digital can’t be overstated. As a trusted innovator delivering technologies that ensure America leads the world in military strength, Northrop Grumman is ushering Sentinel – the nation’s strategic deterrent – into the digital age.

Born Digital

Northrop Grumman’s digital ecosystem is the foundation of how the company designs, builds and sustains some of the most advanced defense systems in the world, including the B-21 Raider.  Innovative digital technologies and advanced manufacturing processes have resulted in the B-21 coming in below the government’s affordability targets, all while successfully scaling into production and achieving technical and performance requirements. Influenced by these learnings, Sentinel was designed from the ground up within an already established digital framework. Since its inception, Sentinel has benefitted from Northrop Grumman’s pioneering digital technology and engineering innovations that increase speed and efficiency, reduce risk and drive performance.

Northrop Grumman is transforming the way weapons systems are designed and produced, leveraging its fully connected digital ecosystem and a comprehensive digital thread to facilitate enhanced collaboration among Sentinel program teams, government partners and suppliers across the nation. The digital thread will connect teams across geographical, regional and classification barriers, creating a single source of truth and driving continuous progress for the program. This accelerates delivery timelines, enhances quality, and drives mission success.

Digital modeling doesn’t stop with the design. The Sentinel digital ecosystem provides a comprehensive system model that will guide decision making throughout the life of the program. Leveraging a myriad of analyses – from analyzing regional workforces to modeling traffic patterns and vehicle routes – the model will inform the government and industry team of ways to optimize program schedule, reduce costs and buy down risk.

Modernizing for Missileers

Missileers will benefit from the system’s new digital interface that delivers more data faster than ever before. The software upgrades enable rapid missile maintenance, providing direct insight into where faults may be occurring and how to respond. Imagine your car telling you exactly where the problem is and how to fix it.

Sentinel systems will prioritize ease of navigation, ensuring operational readiness for Airmen. This represents a dramatic maintenance capability enhancement by providing the ability to deploy fixes in minutes rather than months. This means Sentinel’s system will remain resilient and highly responsive.

Future-Proof

Sentinel is designed to be in service for the next 50 years to deter adversaries and ensure peace through strength. Modern, powerful and adaptable, Sentinel’s digital infrastructure ensures long-term resilience against future threats. Northrop Grumman is creating the foundation for decades of performance through modular open systems architectures and improved reliability and maintainability.

Northrop Grumman is on the leading edge of technology innovation. From engineering and supply chain management to manufacturing, production, and sustainment, the company is embedding advanced digital technologies into every phase of the Sentinel program.

Summary

Northrop Grumman modernizes the nation’s strategic deterrent with Sentinel, a digitally engineered ICBM system designed for enhanced collaboration, rapid maintenance, and long-term resilience in national defense.

Key Takeaways

  • Sentinel leverages advanced digital technologies to modernize ICBM systems, accelerating delivery and ensuring operational readiness for the next 50 years.
  • Northrop Grumman’s integrated digital ecosystem accelerates defense system production while reducing risks and optimizing mission performance.
