Haven’t we had those since the 50s?
Yeah, but most kept such personal matters private back then.
Stated airspeed (the unclassified airspeed that is) of current ICBMS is roughly 17,647 mph, with a max range of 8,000 miles with an accuracy of 800 feet radius of target point! 800 feet in 8K miles. Course the warhead doesn’t have to be precise like an artillery shell
Their 7K mph is actually slow. 30 mins to the US? What part?
As example: 5740 mile from central Montana to Beijing at 17647 mph is arrival time at 19 minutes— assuming stationary land based launch. Much faster from other delivery means... subs, aircraft etc, who could be closer in
