ARNOLD AIR FORCE BASE, Tenn. (AFNS) — \u00a0<\/strong><\/p>\n

The U.S. Air Force, in partnership with Northrop Grumman, completed a full-scale qualification test of the stage-two solid rocket motor for the LGM-35A Sentinel intercontinental ballistic missile, July 20, by the 717th Test Squadron at the Arnold Engineering Development Complex<\/a><\/strong>.\u00a0<\/p>\n

The test marks a critical milestone in the ongoing effort to modernize the nation\u2019s land-based nuclear deterrent. Conducted in a vacuum chamber to simulate high-altitude conditions, the test provided essential data on the motor\u2019s thrust, burn profile, and steering capabilities via its thrust vector control system.\u00a0

\u201cThis test reflects our disciplined digital engineering approach and the continued momentum behind the Sentinel program,\u201d said Brig. Gen. William S. Rogers<\/a><\/strong>, Air Force program executive officer for ICBMs and director of the ICBM Systems Directorate, Air Force Nuclear Weapons Center<\/a><\/strong>. \u201cWe\u2019re not just testing hardware \u2014 we\u2019re proving that our models are accurate, our development timeline is achievable and the system will be ready to deliver when called upon.\u201d\u00a0
\u00a0
The stage-two motor is one of three booster segments that make up the three-stage Sentinel missile. This test is part of a series intended to qualify the stage-two design and validate predictive performance models developed in a digital engineering environment. The data gathered from this test will be used to refine design elements and reduce technical risk as the program moves toward production.\u00a0
\u00a0
The milestone follows the stage-one rocket motor test conducted in March<\/a><\/strong> at Northrop Grumman\u2019s facility in Promontory, Utah. That test verified motor performance and alignment with digital models, setting the foundation for the next phase of qualification testing.\u00a0
\u00a0
\u201cThis isn\u2019t just about one motor test,\u201d Rogers said. \u201cIt\u2019s about building confidence \u2014 in our engineering; in our program schedule; and, most importantly, in our ability to deter aggression and defend the nation.\u201d\u00a0
\u00a0

The Sentinel program\u2019s model-based design approach allows engineers to simulate system behavior, improve accuracy in performance predictions and reduce reliance on costly hardware prototypes. The Air Force and Northrop Grumman will continue stage-two qualification testing throughout the year, with upcoming tests planned to evaluate additional motor components under varied environmental conditions.\u00a0
