The U.S. Air Force’s Ground Based Strategic Deterrent (GBSD) is the weapon system replacement for the aging LGM-30 Minuteman III intercontinental ballistic missile system (ICBM). GBSD represents the modernization of the ground-based leg of the nuclear triad.
The Minuteman III first became operational in the early 1970s. While certain components and subsystems have been upgraded, most of the fundamental infrastructure in use today is the original equipment supporting more than 50 years of continuous operation.
On August 21, 2017, Northrop Grumman was one of two companies awarded a Technology Maturation and Risk Reduction contract for the new GBSD weapon system program.
The Air Force is focused 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.
