You could be right but I doubt it. The nice thing about this weapon compared to a missile is that the bullets are pretty cheap. Compared to a missile. Getting hit by a chunk of stuff coming at you at 4500 MPH would really hurt.
Somali pirate surprise?
4500 mph? That’s only Mach 6. I once worked on missiles that were faster than that. I think someone got the wrong information.

That is the “un-classified” speed. Research papers say 7000 MPH.
Yes at 125 miles the slug will be less speed than it left but not much. It will go through a “Lot” of concrete and kill a lot of people inside a concrete building. It will tear right through most armor because of the speed which is a force multiplier. There is no armored vehicle that can be protected from that kind of speed.
The speed is something like a hundred miles a minute. I would not want to be on the receiving end.
