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.
