Ground Based Strategic Deterrent is a US land-based intercontinental ballistic missile system in the early stages of development, slated to replace all 450 Minuteman III missiles in service with the United States Air Force from 2027 onward.
A request for proposal for development and maintenance of a Ground Based Strategic Deterrent next-generation nuclear ICBM, was made by the US Air Force Nuclear Weapons Center, ICBM Systems Directorate, GBSD Division on 29 July 2016. The GBSD would replace the Minuteman III in the land based portion of the US Nuclear Triad. The new missile to be phased in over a decade from the late 2020s are estimated over a fifty-year life cycle to cost around $86 billion. Boeing and Northrop Grumman are competing for the contract. On 21 August 2017 the US Air Force awarded 3-year development contracts to Boeing and Northrop Grumman, for $349 million and $329 million, respectively. One of these companies will be selected to produce this ground-based nuclear ICBM in 2020. In 2027 the GBSD program is expected to enter service and remain active until 2075.
