In a significant stride toward fortifying the nation’s defense capabilities, the US Air Force is forging ahead with the development of the LGM-35A Sentinel, set to replace the aging Minuteman III intercontinental ballistic missile (ICBM).

The Sentinel, a cornerstone of the Ground Based Strategic Deterrent (GBSD) program, marks a pivotal leap in nuclear deterrence technology, backed by a recent milestone in the procurement of the MK21A Reentry Vehicle.

Enhancing National Security: The Sentinel Initiative

The Air Force Nuclear Weapons Center recently unveiled a momentous contract award totaling $996.2 million to Lockheed Martin, aimed at steering the design and construction of the MK21A Reentry Vehicle—a critical component for the future LGM-35A Sentinel ICBM.

The Sentinel weapon system, developed by Northrop Grumman Corp., represents an instrumental initiative to bolster the country’s contemporary nuclear deterrence apparatus.
