The contract does not specify how many guidance systems Boeing must provide for the Minuteman III missiles, but the agreement is expected to run until February 1, 2039, the US Department of Defense said.
The work will be carried out at US Air Force Base Hill Air Force Base in the state of Utah, it still sounds.
The Minuteman III has been in service for fifty years. The missile can carry a nuclear warhead in wartime and is the only one in the US nuclear arsenal that departs from the ground. The missile is located at bases in Wyoming, North Dakota and Montana.
In September, the Pentagon conducted another test flight with the missile. The operation was announced in advance to prevent tensions with Russia from escalating amid the conflict in Ukraine.
The unarmed missile was launched from Vandenberg Air Force Base in California and flew 6,760 kilometers across the Pacific Ocean before crashing into the sea near Kwajalen Atoll.
