Northrop Grumman and U.S. Air Force Assemble Inert Sentinel Missile, Clearing Path for 2027 Flight Tests
Event summary
- Northrop Grumman and the U.S. Air Force successfully assembled an inert Sentinel missile in its operational orientation, a critical step toward 2027 flight testing.
- The vertical assembly at Vandenberg Space Force Base validated the integration of all missile stages, propulsion elements, and associated components.
- The first flight test Critical Design Review confirmed the missile’s design maturity and readiness for performance, safety, and schedule requirements.
- The Sentinel program, a modernization of the U.S. ground-based nuclear triad, aims for initial operational capability in the early 2030s.
The big picture
The successful assembly of the Sentinel missile marks a significant milestone in the modernization of the U.S. ground-based nuclear triad. As Northrop Grumman advances toward flight testing in 2027, the program’s progress reflects broader trends in defense modernization and strategic deterrence. The Sentinel missile, designed to be viable through 2075, underscores the long-term investment in advanced ICBM technology and the critical role of private-sector partnerships in national security.
