Army Gets Aerial Boost From Company's 155mm Artillery Rounds That Can Travel 150 Kilometers

Tiberius and the U.S. Army are establishing guidelines on Sceptre, a ramjet-powered 155mm round designed for longer-range precision strikes.

Tiberius Aerospace has entered into a Cooperative Research and Development Agreement (CRADA) with the U.S. Army Combat Capabilities Development Command Armaments Center to advance Sceptre, its liquid-fueled, ramjet-powered 155mm precision-guided artillery round. The agreement establishes a formal framework for Tiberius and the DEVCOM Armaments Center to conduct mutually agreed research and technical work related to Sceptre. The Army uses CRADAs to collaborate with private companies on research and development, but the agreements are not procurement contracts. Sceptre is designed to fire from existing NATO-standard howitzers without requiring a new launcher or firing platform. Tiberius says the round is intended to travel as far as 150 kilometers, accelerate beyond Mach 3, climb above 65,000 feet, and strike within 5 meters of a target—including in environments where GPS signals are unavailable or disrupted. The Army agreement provides a new research framework as Tiberius works to mature the propulsion, guidance and software technologies required to achieve them.
