Can you provide a link to the original rumor? Or the original text?Hey the guy pop said Chines EMRG has max initial speed of 11km/second. That would be 30+ mach! If it was a typo for 1.1km/second, it would be too slow.

If he meant 11000km/h, this would be about 3km/second which seems realistic for a railgun.Hey the guy pop said Chines EMRG has max initial speed of 11km/second. That would be 30+ mach! If it was a typo for 1.1km/second, it would be too slow.

11 km/s would mean that the gun can fire shells into low Earth orbit. Sounds unrealistic IMHO.

I just had a quick glance of the screenshot. Will post here if i can find it. Too good to be true honestly.Can you provide a link to the original rumor? Or the original text?

had they shot a 3.2 kg (= seven pounds) projectile (as BAE did), they would've had roughly a (don't nitpick) 200 MJ (two-hundred megajoule) gadget;Hey the guy pop said Chines EMRG has max initial speed of 11km/second. ...

had its pumping time been 1s, they would've needed 200 MW to shoot it meaning a dedicated electric power plant attached LOL

by the way 200 MJ is not THAT much; from my older posts:

Feb 1, 2018

plus an estimate for 'cargo' Feb 3, 2018in the example Today at 7:30 AM

a striking velocity of 514 m/s is for a muzzle velocity of 762 m/s (the link is )

so 1225 kg weighing AP Mk8 shell would loose

(0.5*1225*762^2-0.5*1225*514^2)/(0.5*1225*762^2)

about 55%, but still had the energy (of 162 MJ) several times higher then the current (32 MJ) US railgun they were considering to ax anyway Dec 7, 2017

...

means more than 200 MJ in total...

an AP Mk8 shell from that example had 1.5% of Explosive D (according to Campbell's Naval Weapons of WW2),

and I didn't find its TNT equivalent, so assuming there were 18 kg "of TNT" inside, it'd mean about 75 MJ released ();

so the kinetic energy of said shell hitting as in that example, about 162 MJ, would be actually higher than of the burster
