The Sceptre achieves speeds of Mach 3.5, with operational altitudes exceeding 65,000 feet, putting it beyond the reach of most conventional countermeasures and GPS jamming systems.

This design uses a ramjet propulsion system, which is uncommon in artillery shells.

This feature allows the shell to travel at high supersonic speeds for distances of up to 150 km (100 miles), depending on its payload.

It runs on diesel and has a CEP of 5 meters :)

America needs to bring back the Big Battleship and fill it full of artillery like this.

I read the big guns on the Iowa shot a projectile with the mass of a VW Bug.

Also the US needs fireboats!

Still no national healthcare.

But we have more ways to kill people than any other country in the world!

USA! USA! USA!

War is in charge of us, we don't seem to be charge of our country and its ability to feed and house and heal the sick and poor.

hmm...
speed of sound in dry air at 20 C =
343 m / s

155 mm Howitzer M114
Muzzle velocity 1,850 ft/s (563 m/s)
(already supersonic)

155mm ramjet-powered, liquid-fuelled munition
so, a missile? I hope they us a very long pull-string to set it off.

The representative from the startup, Mr. Haney from Hooterville, could not be reached for comment, although the development funds were dispersed earlier that day.
