US new Supergun can fire over 100 miles eight time faster than sound

A gun can fire over 100 miles eight time faster than sound, can you believe this?

Yes US has developed such gun which can do this miracle.
According to Daily Mail "This Supergun has been described as the most powerful in the world after tests at a U.S. Navy firing range.

The bullet would take just minutes to fire over 100 miles and would hit with pinpoint accuracy with a velocity that's impossible in conventional guns, The speed is eight time faster than sound.

Rear Admiral Nevin Carr, chief of naval research, said the gun could be aimed at a magazine on an enemy ship and ‘let his explosives be your explosives’.

Currently US war ships can fire at 13 miles away but this super gun will allow them to hit from safer distance with unbelievable pinpoint accuracy.

At last I would like to say, No doubt, This is really a great invention for US but worthless for humanity.
