Tiberius Aerospace Unveils Sceptre, a Ramjet-Powered Precision Artillery Round
Their new missile, Sceptre, can fly at Mach 3.5.
Tiberius Aerospace, a new UK-headquartered defence company with roots in Silicon Valley, has emerged from stealth to announce its flagship product: Sceptre (TRBM 155HG), a 155mm extended-range precision-guided artillery munition powered by a liquid-fuel ramjet.
Launched ahead of the Future Artillery conference in London, Sceptre is the company’s answer to modern battlefield demands for low-cost, long-range precision fires that can survive in contested environments. The system reportedly achieves speeds of Mach 3.5, altitudes over 65,000 feet, and a strike radius within 5 metres—even in GPS-denied conditions.
With a range up to 150km depending on payload, Sceptre dramatically outpaces traditional artillery, offering a potential 10x improvement in cost-effectiveness and precision. It’s fully compatible with NATO 155mm platforms and introduces a modular design with open architecture for future software and hardware upgrades. Notably, the munition is designed to use standard military fuels (diesel, JP-4, JP-8) in a just-in-time liquid propellant system—an approach that minimises storage risks and extends shelf life beyond 20 years.
Tiberius claims the system also reduces barrel wear and logistics complexity. During flight, onboard AI-assisted guidance integrates GPS, inertial measurement data, and even real-time communication between rounds to adjust targeting on the fly.
“This is about filling a critical capability gap,” said Chad Steelberg, Founder and CEO of Tiberius Aerospace. “Sceptre delivers long-range precision-guided effects in a cost-effective package. It’s the first step in a broader innovation pipeline that prioritises scale, resilience, and sovereign agility.”
Tiberius Aerospace was founded in 2022 with a mandate to rethink defence manufacturing and delivery. Its Defence-as-a-Service model separates R&D from production, enabling rapid iteration and sovereign supply chain integration. The company’s broader roadmap includes autonomous platforms, missile systems, and AI-enabled weapons tailored for interoperability across allied nations.
