Northrop Grumman Redesigning Intercontinental Ballistic Missile Target Vehicle Using Digital Technologies

CHANDLER, Ariz. August 27. Northrop Grumman Corporation is redesigning the Intercontinental Ballistic Missile (ICBM) target vehicle for the Missile Defense Agency (MDA). The new design replaces the target’s heritage Trident C4 first stage solid rocket motor with a Peacekeeper SR119 motor to provide extended range, lift capability and payload capacity for ICBM target missions.

• Northrop Grumman leveraged virtual and augmented reality to fully animate and validate the target vehicle’s new integration and stacking operations, which will be demonstrated later this year.
• Northrop Grumman modified the retired SR119 rocket motor to serve as a first stage motor, meeting mission performance requirements with minimal changes to its original design. The new ICBM design creates target longevity to support future missile defense testing.
• The company completed the Critical Design Review of its redesigned ICBM target earlier this month, and the redesigned vehicle is slated to take its first flight in late 2025. It will be compatible with advanced front ends to simulate sophisticated, long-range ballistic missile threats.

Expert:

Robin Heard, Director of Targets, Northrop Grumman: “Our approach to building target vehicles enables us to pair new and proven technologies together to create the best solution to meet customer needs. It’s about finding the right balance of affordability and innovation – combining capable, government-owned surplus motors and sophisticated front ends to simulate current and emerging threats.”

Details:

ICBM target vehicles are threat-representative ballistic missiles used by the MDA to test the efficacy of the nation’s missile defense systems, including the Ground-based Midcourse Defense System and Aegis Ballistic Missile Defense System. Northrop Grumman is the prime contractor for the Intermediate Range Ballistic Missile and ICBM target vehicles, delivering 25 vehicles to date and supporting 10 successful launches since 2011.

The redesigned ICBM target is Northrop Grumman’s first target program to leverage virtual and augmented reality to fully animate the vehicle’s factory integration and field operations, known as pathfinding. Pathfinding provides a lower risk setting to fully vet new integration, stacking and test operations on inert hardware. Virtually simulating the vehicle’s pathfinding operations further buys down risk, enhances end-to-end test capability and optimizes processes to deliver the critical capability with agility.

In collaboration with the MDA and the US Air Force Rocket Systems Launch Program, the company successfully completed a static fire of the SR119 solid rocket motor in 2022 and initial SR119 integration pathfinding operations in June 2024. The tests validated the motor’s capability to serve as a first stage in this new target vehicle application.

Northrop Grumman is a leading provider of threat representative target vehicles used in the test and verification of the nation’s missile defense systems. With a portfolio of advanced avionics components and adaptable kits, the company repurposes decommissioned motors to help rapidly configure customer-specified adversarial threats – driving down costs.
