Northrop Grumman and the U.S. Air Force have fully assembled the Sentinel intercontinental ballistic missile in its operational orientation, a milestone the company says keeps the program on pace for a flight test in 2027. The vertical stacking at Vandenberg Space Force Base, part of a four-month test event known as Pathfinder, proved that all missile stages, propulsion elements, the shroud and associated components have been integrated into a single missile configuration and that the assembly process is executable on the test pad. In parallel, Northrop Grumman and the U.S. Air Force's 719th Test Squadron completed the first flight test Critical Design Review, confirming the missile's design maturity and hardware testing meet Air Force requirements for performance, safety and schedule. Amanda Davis, Northrop Grumman vice president and general manager of strategic deterrent systems, said the assembly demonstrates momentum toward test launching Sentinel in 2027 and having missiles on alert by the early 2030s. Northrop Grumman leads a nationwide team of more than 500 partners under an engineering and manufacturing development contract for the Sentinel program, which is modernizing the ground-based leg of the U.S. strategic nuclear triad and is intended to remain viable through 2075.
