So it leaves the gun traveling at Mach 7 and can go 100 miles but how fast is it going when it reaches the target 100 miles away? By the time it reaches the target most of it's energy is lost. The main power of this weapon is the kinetic energy it delivers to the target but that information is nowhere to be found in the article.

The one they plan to deploy is supposed to go something like mach 20 and have a ballistic trajectory. Not something you could destroy a city with, but it'll make a bigger bang than an 8-inch shell.


Navies still get an awful lot of leverage out of the ability to destroy merchant vessels.
