Northrop Grumman test fires full-scale Sentinel ICBM stage-2 solid rocket motor

Northrop Grumman completed a live, static-fire test of a Sentinel intercontinental ballistic missile (ICBM) stage-two solid rocket motor at the U.S. Air Force Arnold Engineering Development Complex. The test was conducted in a vacuum chamber simulating real-world environmental conditions the solid-rocket motor would experience during high-altitude and space flight. [...]

This test was conducted under the company’s engineering, manufacturing, and development (EMD), or design contract for Sentinel. Northrop Grumman continues to perform on this phase and is working closely with the Air Force on progressing EMD milestones. The Sentinel program is a modernization of the U.S.’s ground-based leg of the strategic triad and is designed to be viable through 2075. [...] On February 16, 2023, Northrop Grumman announced it had successfully completed a series of wind tunnel tests of the LGM-35A Sentinel intercontinental ballistic missile (ICBM). Using scaled models of the vehicle, stressed under environments from sub to hypersonic speeds, the robust test campaign validated digital modeling and simulations and proved design maturity of the missile.
