Northrop Grumman Advances Sentinel Design Phase With Key Tests

Northrop Grumman Corporation successfully completed tests of several crucial elements of the Sentinel intercontinental ballistic missile (ICBM), marking significant progress for the program in its engineering, manufacturing and development phase.

Forward and aft sections of a Sentinel ICBM missile were evaluated through a rigorous test campaign at the company’s Strategic Missile Test and Production Complex in Promontory, Utah. The tests lower risk for the program with important data about the missile’s inflight structural dynamics. Data from the tests help engineering teams mature models, lower risk and ensure flight success.

The shroud fly-off and missile modal tests were part of the company’s engineering, manufacturing, and development (EMD), or design, contract for Sentinel. Northrop Grumman is closely partnered with the Air Force as the EMD phase progresses and key milestones are achieved.

Sarah Willoughby, vice president and program manager, Sentinel, Northrop Grumman: “Working with the Air Force and our team of suppliers, we put key elements of the missile’s hardware to the test to mature our design and lower risk. The shroud fly-off test proved our modeling predictions are solid, while the missile stack test demonstrated inflight missile performance, helping validate assumptions and fine-tune models. These successes give us confidence as we continue progressing on the path to deliver a safe, secure and reliable capability to the nation.”
