The solution is shotguns with a rate of fire akin to a minigun. If you saturate the air and everything around it in a wall of bullets it's not getting through that.
Outspending China on maglev, but its only for terrorizing minority urban populations, ultimately going unused because they're less reliable than 150 year old handgun designs.
Against hypersonics, this isn't really a solution.
The missiles are designed to force their way through thousands of pounds of air per second. Adding a few ounces of lead and/or hardened steel in the last few milliseconds before impact won't do much.
Put lipstick and false eyelashes on an other missile. This will make the hypersonic missile go "oh la lala!" and make it's eyes pop. It will then chase after the girl missile, forgetting everything about where it was going.
The iron dome but for real. We encapsulate the entire west in a giant iron tank and the missile will just boink right off it.
I will need 600 billion dollars to maybe possibly build this.
Ngl, a version of Metalstorm that shoots those firefighting grenades that Thailand developed would be sick. Or convert old A-10s and load up their rotary cannons with them and use them to strafe forest fires and give them some sick red firetruck livery and call it Operation Extinguisher or something. In conclusion, government give me money for my cool ideas.
It looks like the company went into administrative bankruptcy and all they've done in 10 years is sell exploding drones to Australia, who sent them to Ukraine
