Promises and promises: American Tiberius presented a "revolutionary" 155 mm artillery projectile

The American company Tiberius Aerospace, founded in 2022, announced the creation of the Sceptre TRBM 155HG precision-guided missile capable of hitting targets at a distance of up to 150 km. However, despite the ambitious technical specifications, no data on actual tests of the munition has been made public.

Here's What We Know

At the Future Artillery conference in London, the company said that Sceptre is a 155mm munition with a straight-through jet engine that provides speeds of up to Mach 3.5. The payload is 5.2kg and the weight of the entire munition is 47.5kg. According to the manufacturer, the projectile has a circular probable deviation of less than 5 metres and is resistant to EW due to inertial navigation with artificial intelligence support.

A technical feature of the Sceptre is its ability to fly at altitudes of up to 65,000 feet (about 20 km), which allegedly makes it less vulnerable to interference and increases accuracy. The company claims that the projectile is compatible with most NATO artillery systems, despite its 1.55 metre length, and minimises wear on the gun barrel by reducing contact points.

At the same time, KNDS France, a leading European artillery manufacturer, reminds that safe and effective use of ammunition is only possible if it is fully compatible with guns and undergoes extensive testing. For example, the CAESAR system has shown zero incident statistics only due to years of testing and a thorough understanding of the wear and behaviour of projectiles in the barrel.

Tiberius Aerospace has not provided any evidence of actual testing of the new munition. This gives rise to justified skepticism, given that the development and qualification of new weapons usually takes years. For now, the Sceptre project remains an ambitious concept with showy performance, awaiting proof of effectiveness in real-world conditions.
