The UK Ministry of Defence (MoD) has awarded Tiberius Aerospace a contract to develop a liquid-fuelled 155mm ramjet artillery round capable of engaging targets at distances up to 150 kilometers (93 miles). According to the company, the munition delivers pinpoint precision with a circular error probability (CEP) of under 5 meters (16 feet).
For comparison, the US Army’s M982 Excalibur has a maximum range of around 40 kilometers (25 miles). In 2023, the service began pursuing extended-range projectiles that could reach at least 70 kilometers (43 miles) when fired from 52-caliber guns. Conventional artillery rounds, in contrast, typically have a CEP of about 100 meters (328 feet).
The Tiberius shell travels at Mach 3.5, reaching altitudes above 65,000 feet (19,812 meters), which helps protect it from electronic jamming. To ensure accuracy in GPS-denied environments, the munition combines GPS guidance with an inertial measurement unit (IMU), enhanced by AI-based error correction. Multiple rounds can also share targeting data in flight to further improve strike accuracy.
