Trump's statement about the “imminent creation of the greatest weapon in the US” sparked a discussion on the net

unacceptable damage. (Before that, it was equal to 20 million people).

I’ll clarify some of the questions you have raised in doubt:

In the 1950s, Jerry Purnell, who worked at Boeing, suggested using similar ammunition for bombing from orbit. In the West, this concept was called Rods of God, and the military still makes no attempt to put it into practice ...
The latest open documents of the U.S. Air Force are talking about tungsten rods 6,1 m long and 0,3 m in diameter, weighing 9 tons each. The simplest rudders and a miniature control system capable of providing a probable circular deviation of less than 30 m are placed at the rear end of such a rod. Hitting the target, such a projectile will move at a speed of 3,4 km / s, gaining kinetic energy of 5,8 million joules per kilogram of mass. For comparison: TNT releases less than 4,2 million J / kg in an explosion. Tungsten falling from heaven is more powerful than conventional explosives, and whole tungsten scrap will have a TNT equivalent of at least 11,5 tons.
If we want to drown the cruiser, then the best is hard to wish for. For example, the tactical nuclear weapon “Davy Crockett” during the Cold War had the same TNT equivalent of 10–20 tons. Moreover, Crockett’s circular probable deviation was as much as 240 m, which reduced the probability of hitting the target by almost a hundred times. No matter how funny it may sound, the scrap falling from outer space is more effective than the light tactical nuclear weapons of the Cold War era. Fortunately, putting this mass of metal into orbit for impact is still a monstrously expensive enterprise. The American shuttles could take no more than three of these rods, while it would take at least several weeks and half a billion dollars to prepare the launch.
Thanks to a powerful reusable carrier, SpaceX is going to reduce the cost of launching cargo into space, according to Elon Mask, “by 50 thousand times.” At the same time, even in the basic version, it will be able to deliver 100 tons to a low Earth orbit, and subsequently, the carrying capacity will be increased by another half. Even if Musk does not achieve the intended goal, the launch of a serial BFR is unlikely to be more expensive than $ 5 million. That is, delivery of one “rod of God” to the target will come out no more than half a million. It would seem to be too expensive. However, each hour of a B-2 flight costs more than $ 150, and a subsonic bomber requires at least 10 flight hours to hit a target. And it costs more than 3,3 billion. At the same time, the TNT equivalent of non-nuclear bombs delivered to the target by B-2 is only 10-15 tons, like a single tungsten rod (BFR can carry 10-15). Beat B-2 can stop the air defense. But to destroy more than a dozen refractory crowbars in hypersound will be difficult and promising S-500.

And where does the satellite inspector .... He is not for observation ...

You don’t see him. Who needs he greets him at every turn
