Before the Railgun, there was the Combustion Light Gas Gun. It was designed to lob 155mm shells two hundred miles. The self guided projectiles had not been developed at that time, so the accuracy was not sufficient for an inert round. Inconsistent ignition of the gaseous propellant resulted in a significant ranging error, what with an unstable muzzle velocity.
A possibility is that the projectile would be fired using the CLGG system on a trajectory to clear the atmosphere, given an initial muzzle velocity of 2.5 to 4.0 km second. A secondary boost from a laser system supplying energy to a solid propellant block on the projectile base, could provide the additional velocity which would allow extended range.
Or, a really wicked energy-dense internal range extender propellant has been developed.
Why invent the wheel. We have munitions that can be effective to within a few meters at that distance. They are called rockets.
What is the purpose of a new “super gun” in an already expensive arsenal.
When the armed forces are not advertising their women in arms or the need for them, they are advertising their latest tech, perhaps to induce more recruits and or justifying their budget, thereby inciting the Russians and Chinese to focus on coming up with the same.
What used to be kept secret is not advertised.
Good job for carrier based aircraft or B-52s from somewhere far way.
They did attract attention.
It proved itself at Torra Borra.
In WWII there weren’t any guided munitions. It all had to be done the hard way. The loss of life during the Pacific island hopping campaign is saddening. It was difficult to tell were cave openings were located, and there were usually more than one that covered a particular spot. It was a slug-fest.
it was probably hilarious to watch too
