The Sentinel program, originally named the Ground Based Strategic Deterrent (GBSD) by the U.S. Air Force, is the weapon system replacement for the aging LGM-30 Minuteman III intercontinental ballistic missile system (ICBM). Through Sentinel, the U.S. Air Force aims to modernize the nation’s aging force of ICBMs, the land leg of the U.S. nuclear deterrent through this program with a focus on developing and delivering an integrated weapon system that will meet the combatant commander’s current requirements, while having the adaptability to affordably address changing technology and emerging threats through 2075.
In the early 1970s the Minuteman III first became operational. While certain components and subsystems have been upgraded through the years, most of the fundamental infrastructure in use today is the original equipment supporting more than 50 years of continuous operation. We’re honored to be a part of a team helping to modernize this piece of our nation’s history as a way to protect our country’s future.
Bechtel will provide launch infrastructure design and construction as part of the program’s Engineering and Manufacturing Development phase.
