Defense technology company Tiberius Aerospace has publicly launched its first product, the Sceptre ramjet-powered artillery munition, marking its emergence from stealth mode after three years of development. The Sceptre (TRBM 155HG) is a 155mm extended-range precision-guided munition designed for use with existing NATO artillery platforms. The weapon utilizes ramjet propulsion technology to achieve speeds of Mach 3.5 and can reach altitudes exceeding 65,000 feet, according to the company. Several established defense manufacturers, including Nammo and Rheinmetall, have introduced RAMJET-powered, extended-range artillery munitions, yet none have been fielded. With active propulsion, Sceptre flies at altitudes in excess of 65,000 feet and remains beyond the enemy EW jamming range for the majority of its flight trajectory.
