Rheinmetall BAE Systems Land (RBSL) has completed a series of Battlefield Mission serials for the Challenger 3 main battle tank, marking what the company describes as an important step forward in the programme’s development activity, according to a post on the company’s social media.
The trial platforms operated in representative conditions across a range of activities including cross-country mobility, road running, gunnery equipment operation, and full crew drills. Data and observations gathered are being fed directly back into the engineering baseline to support continuous improvement and ongoing maturation of the platform.
Nick, RBSL Programme Lead for Verification, said the activity was generating exactly the learning the programme needed at this stage. “Every serial helps build understanding, improve processes and strengthen confidence as we prepare for future formal trials.”

RBSL said the serials were also helping validate procedures, instrumentation, and trial methodologies ahead of formal trial phases. The work is being delivered in close collaboration with MoD stakeholders and industry partners.
Challenger 3 is the upgrade programme for the British Army’s Challenger 2 fleet, incorporating a new turret with a 120mm smoothbore gun compatible with NATO standard ammunition, a new fire control system, and improved sights. The upgrade is being delivered by RBSL, the joint venture between Rheinmetall and BAE Systems. The Army has contracted for 148 tanks to be upgraded to the Challenger 3 standard.
The UK should make efforts to acquire Omans challenger 2 tanks even if we don’t initially plan to use them. Challenger 3 appears to be one of the most capable MBTs on the planet and the program cost is quite modest. There may be future room to growth fleet and the only limitation appears to be the older hulls to work with although I have noticed that BAE appears to be offering it for export presumably with new hulls manufactured.
However a large reserve fleet of challenger 2 hulls in storage would be very useful either way.
If Oman was in a hurry to rid itself of those 38(?) tanks, would not Ukraine be a better recipient? At least there, they could make up BCRs for the UAF and make up a larger force.
Which then feeds into the argument that perhaps, if we have more hulls which could be returned to service (hold that thought), should they not be donated to the UAF.
Economics. As a generalisation, Central Europe has often been a more cost effective place for manufacturing; little known fact, our steel for HS2 was coming from Ukraine; should we not donate those hulls declared unserviceable to the Ukrainians who might possibly make them battle worthy at less cost than the UK could hope to achieve?
148, a ridiculous and insufficient number. Of course, this government didn’t order it because they haven’t ordered anything other than bringing in and harboring illegal immigrants to change the country’s demographics. Isn’t that genocide?
Cobblers would be more apt.
That’s not being done by illegal immigration. Illegal immigration numbers are a drop in the ocean compared to the legal immigration numbers. When you go around our towns/cities and see the massive demographics change, that’s all happened via legal means. The governments over the last few decades have done that through choice with their policy.
It says “Tank”.
I’m hoping we actually get more than one.
You never know with this bunch of DIP sticks at the helm !
