The UK Ministry of Defence has partnered with Tiberius Aerospace to push the boundaries of long-range artillery through the development of a 155mm ramjet-powered precision munition. The liquid-fuelled projectile is capable of engaging targets at distances up to 150 kilometers, with accuracy measured within a CEP of less than five meters. Such precision is unprecedented in artillery fire.
This far surpasses current benchmarks. The U.S. Army’s M982 Excalibur, for instance, has a maximum effective range of roughly 40 kilometers, while its next-generation efforts aim for 70 kilometers. Standard unguided artillery shells, meanwhile, offer only limited accuracy, with a CEP of around 100 meters. The Tiberius round represents a step change in range, accuracy, and survivability.
At Mach 3.5 and operating above 65,000 feet, the shell’s flight profile keeps it out of reach of most jamming and countermeasures. Guidance is maintained through a GPS-IMU pairing enhanced by artificial intelligence, ensuring resilience in contested or GPS-denied environments. The IMU provides orientation and position data, while AI-driven corrections compensate for errors when external signals are lost.
In addition, the munition includes a cooperative targeting mode. Multiple rounds can exchange data in real time, aligning trajectories to strike targets with greater precision or to overwhelm defenses with coordinated impact.
