Tiberius Aerospace has been awarded a contract by the UK Ministry of Defence (MoD) for the rapid trial and development of its liquid fuelled, 155mm Ramjet extended-range precision-guided artillery munition, called Sceptre (TRBM 155HG).
The contract puts the UK MoD in the position of being the launch customer for Tiberius Aerospace. The US Defence Innovation Unit (DIU) is also facilitating the independent verification and validation for the testing of the technology.
Sceptre (TRBM 155HG) is a new 155mm ramjet extended-range precision-guided ballistic munition reaching speeds of Mach 3.5 and altitudes in excess of 65,000 feet (beyond jamming range). Sceptre has an extended range up to 150km depending on payload (max 5.2kg) and superior targeting precision with a circular error probability (CEP) of less than 5m, even in GPS contested battlespaces, compared to over 100m for traditional artillery.
Designed with the customer and end user foremost, the system is fully compatible with NATO standard 155mm artillery platforms and its ignition system and limited barrel contact points minimises barrel degradation. To reduce the logistics burden, minimise storage and in-transit safety hazards, and maximise shelf life beyond 20 years, Sceptre uses a proprietary just-in-time, multi-fuel (diesel, JP-4 and JP-8) liquid propellent design.
“Since the launch of Sceptre in May 2025, Tiberius has evolved the capability at pace through a series of high tempo live-firing and synthetic test cycles," said Andy Baynes, co-founder and CSO of Tiberius Aerospace. "We’re delighted to announce this UK MoD contract which has invested early in our technology development cycle. This is testament to the UK's visionary leadership and their understanding of the importance of driving innovative solutions such as Sceptre and Defense-as-a-Service to increase national security.”
