Ushering in the Next Generation of Missile Defense

Leveraging a legacy of expertise and state-of-the-art manufacturing facilities to accelerate production and reduce risk

The Next Generation Interceptor evolves our homeland defenses to defend against increasingly sophisticated ballistic missile threats. We’ve proactively invested in manufacturing facilities and capacity to produce solid rocket motors affordably and at scale. Our robust supply chain is key to enabling our nation’s need for cost-effective missile defense production. Our end-to-end kill chain heritage is defined by flight-proven ground systems, battle management, command and control systems, and interceptor boost vehicles and kill vehicles. Innovative technologies, agile processes and proven facilities underpin our ability to deliver a custom solution tailored for the mission need.

Digital Transformation

Accelerating operations and strengthening performance

Northrop Grumman is harnessing integrated digital technologies to rapidly conceptualize, design, build, and sustain value-driven solutions. Our customers are looking for faster cycle times and more affordable systems to counter rapidly evolving threats with a need to maintain capability and capacity. We are at the forefront of implementing digital engineering, DevSecOps and Agile principles and practices across our portfolio of new and legacy programs to meet that need.

We leverage disruptive technologies, rapid prototyping, increased additive manufacturing, highly integrated and automated assembly lines, and more advanced modeling and simulation tools to execute design with manufacturing so they are almost simultaneous. Our manufacturing advancements dramatically reduce intensive labor, manufacturing time and cost, while improving quality and reducing risk.
