The Vandenberg Airbase conducted a test launch of the unmanned intercontinental ballistic missile LGM-30G Minuteman III. The test was conducted exactly on the 45th anniversary of the introduction of the first missiles of this type into service. They are currently the only land component of the US nuclear triad.
Americans say the missile was randomly selected and after it had been removed, the nuclear warhead was fired, then flew more than 6,500 miles and reached its destination near the Marshall Islands. Earlier, Minuteman III’s missiles were equipped with several independent nuclear warheads (MIRVs), but within the framework of the disarmament treaties, all (about 450, target 400) now have a single power head of about 300 kiloton.
Despite 45 years of combat readiness in three US bases, Americans still do not even have a candidate for the successor to these missiles. They are undergoing modernization, and most likely by the end of the year, the next generation of projectors will be selected. It is estimated, however, that Minuteman III missiles will remain in service until at least 2030, meaning more than 60 years in combat readiness.
