A car going 30 km/h clears the 30m blast radius of a 900kg bomb in about three seconds, and the 340m fragmentation radius in about 40 seconds.
This means that to hit a moving target at Mach 9 (or about 3 km/s) you need to launch your 11m long rocket within either 9 or 120 km depending on the desired probability for a kill.
As a reference, an aircraft carrier can go over 50 km/h, the Chinese hypersonic weapons go about 1.7 km/s and have a range of at least 1000 km. How does that work out you wonder? Simple, they put nukes on their hypersonic missiles.
- elric 5y ago> an aircraft carrier can go over 50 km/s I'm assuming you mean km/h there? I'd love to see a boat going that fast.
- SiempreViernes 5y agoYeah, thanks for pointing out the typo. Probably wouldn't have spotted it in time to edit it otherwise.
- mLuby 5y agoAs impressive as an aircraft carrier with solar escape velocity would be, I'm betting that's a typo. A 50km/s vessel carrying hypersonic missiles would be like bringing turtles on a transatlantic flight!
