A British defense startup has unveiled a new ramjet-powered artillery round designed to deliver long-range precision effects in future combat environments.
Tiberius Aerospace, founded in 2022 and rooted in Silicon Valley practices, introduced its flagship product—Sceptre (TRBM 155HG)—at the Future Artillery conference in London, running May 20–22.
The company describes the Sceptre as a “revolutionary” 155mm extended-range, liquid-fuelled, precision-guided artillery munition.
According to the company, Sceptre is capable of reaching Mach 3.5 and altitudes exceeding 65,000 feet, placing it outside most electronic warfare interference zones. It is designed to operate effectively in contested electromagnetic environments, with a circular error probability (CEP) under 5 meters, compared to over 100 meters for conventional rounds.
