@Free_Press Good. I mean, it's not like this is something we haven't done before. We did it in the 1960s. Remember the Sprint missile? Yeah. That one.
I grew up in Los Angeles, the "military think tank" and manufacturing center of the USA. LA was ringed with Nike and Sprint sites. During the Cold War, incoming ICBMs travelling at 17,000 MPH would have been intercepted by nuclear tipped ABMs.
The Sprint was the fastest of them all. It launched like a cannon round with 100 G's of acceleration and within a few seconds was white hot(6,000 F) from friction with the air. We did hypersonic in the 1960s. Watch this: https://www.youtube.com/watch?v=kvZGaMt7UgQ
