Tiberius Aerospace has announced it has secured a UK Ministry of Defence contract to support the rapid trials and development of its Sceptre ramjet artillery round, a new extended-range precision-guided 155mm munition.
According to the company, the contract makes the UK the launch customer for its technology, with verification and validation work supported by the US Defence Innovation Unit. Specific contract details have not been disclosed.
Sceptre, formally designated TRBM 155HG, is described by Tiberius as a “revolutionary” munition able to reach speeds of Mach 3.5, altitudes of more than 65,000 feet, and ranges of up to 150km depending on payload. The round is designed to be compatible with NATO-standard 155mm artillery systems and incorporates a liquid-fuelled ramjet using multiple fuel types. The company claims a circular error probability of less than 5m, even in GPS-contested environments, a major improvement over traditional artillery.
Andy Baynes, co-founder and Chief Strategy Officer of Tiberius Aerospace, said: “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. 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 Defence-as-a-Service to increase national security.”
The company says that its approach draws on Silicon Valley practices, with a focus on rapid iteration, agile development, and what it terms “Defence-as-a-Service,” decoupling innovation from manufacturing to support sovereign collaboration and adaptation across allied nations.
Tiberius plans to showcase Sceptre and its broader development model at DSEi in London from 9 to 12 September, where it will also launch its GRAIL platform alongside UK and US defence innovation officials.
Founded in 2022 by Chad Steelberg and Andy Baynes, Tiberius Aerospace says it aims to apply commercial technology expertise to next-generation precision weapons, missile systems, autonomous platforms, and AI-enabled defence capabilities for the UK, US and allied nations.
Well Beam me up Spock, James “T” Kirk gets an order from a UK “Enterprise”.
(It’s all I could come up with).
‘Britain contracts tiberius munition’
I know, this sort of trial spending really is a disease.
How’s that, Halfwit?
Very good, I like the cut of your Jib !
Have you seen tghe T83 article on Janes ? It’s interesting, just a rendition but it does look the Dogs.
TGHE, I was using my big toe.
Just sayin like.
Unfortunately not, because a) Janes is blocked on my school laptop for some reason (‘ads’, apparently!) and b) I don’t have the funds to cough up 300 quid a year for some nice online articles.
Is there anything particularly interesting?
You have Jane’s.. my wife would murder me if I got Jane’s..”sob”.
Well it sounds good.
All we (the UK) need is some weapons to fire them from.
“(tested through) a series of high tempo live-firing and synthetic test cycles.” Really? Have they got a ready-to-go missile and, if so, where did they test fire it?
Now this is the sort of innovation that we need, if it lives up to what it says on the tin. Now let’s hope the talk leads to substance.
When do we get the 155mm Guns to fire them from?
Type 26 …. in about 3 years we get the first.
This would be one hell of a good capability if it is highly accurate/guided which i am sure it will be.
I think the Type 26 frigate will be equipped with the MK45 5-inch (127mm) naval gun system
Well we do have them..just not very many.
