‘Huge success’ China tests 4,563mph hypersonic aircraft that can fire ‘UNSTOPPABLE’ nukes

Satellite defence to stop nukes mid air or upon firing. Space force for the win

We probably can shoot it down with laser weapons...

yes. but can the mechanical gun acquire the target.

So, is this their advertising strategy to sell them to North Korea?

Guess when, and by whom, China gained all it's advanced technology!! They didn't have anything until Bill Clinton!

Boy what would they need a weapon like that for?...Imagine if all these war mongers spent time and money learning how to live. rather than learning how to kill...

Yep. There are several countries that could annihilate one another, including us. Very scary times indeed. I trust our technology and military. I sleep well at night. Plus I know "they" won't allow nukes to fly.

Masers travel as fast as light. Makes 4,563 mph look like grandma with a walker.

It will be no match for our Sharks with lazers.

So like Elon Musk's or Jeff Bezos's reusable rocket technology? If so, I have to give them credit, this is clever. Have the main vehicle go super fast to get behind the defenses, then fire possibly slower warheads on to the defenseless target, then book it out of there and recover the main vehicle.

That looks like a rocket. (Much easier to hit super high speeds with a rocket.) How do they store enough fuel in it to do the whole mission and land safely at the recovery point?

Now we know something that we have to develop. I hope we can steal back some of their tech. to save ourselves time, they've been stealing plenty from us.

It occurs to me that having a lot of fuel in this kind of rocket is not as difficult as using a lot of fuel to get to orbit while paying the weight penalty for lifting the fuel. This rocket doesn't have to fly very high, so it doesn't have to LIFT the fuel, and once the rocket is flying fast, it isn't accelerating the fuel at all, just using it to overcome air drag.

Does air drag go down or not increase as fast at high mach numbers? If so, I think I am starting to understand this innovation.

Dianne Feinstein's "Driver"?

Everyone says they're unstoppable until they get smacked in the face

The hypersonic aircraft, do not HAVE to carry nukes. They can carry conventional explosives. Which means, that a country doesn't have to go "all in" for WW3, but can use them in a conventional war. Such as knocking off aircraft carriers, or command/control centers.

Tactical Nukes will be used, but not the 20 megatonners, of course.
