The RO2004 light tank was a vehicle designed by a Royal Ordnance PLC/BAE consortium in the late 80s as part of the FFLAV programme (Future Family of Light Armoured Vehicles) conducted by the British government. The RO design was modular: the hull design remained the same across all 4 vehicles designed (2001-2004). It’s important however to note that the RO2004 never reached a full prototype stage. The hull was built, and the turret and armament were built and displayed separately, but they were never mated. This still constitutes a worthy suggestion by Gaijin’s criteria, which is why I’m writing this!
The RO2000 hull was made of steel, and had a 320hp engine at the front. In total, the hull weighed 13.5 tonnes and was very small, measuring 6.2 x 2.8 metres (length x width). As seen in the image, the vehicle had 5 double road wheels on either side, with a torsion bar suspension. With the RO2004 turret, the vehicle weighed 21.5 tonnes and could reach a top speed of 55km/h.
The RO2004 turret had a standard shape, and housed a new version of the L7 105mm gun firing the standard British/NATO ammunition. The gun was called the Improved Weapon System (IWS). It has been seen tested on various Leopard 1s (German Leopard 1 and 1A5, and a Canadian Leopard C1) with its’ distinct muzzle-break, and comes with a new APFSDS round – named the ‘T-2-series’ – offering penetration of around 540mm at 2000m. According to Army Guide, the round “weighs a total of 19 kg and is 1.03 m long with a muzzle velocity of 1,420 m/s.” The RO2004 also housed a bustle-mounted autoloader, resulting in a presumed high ROF. The turret also had the option of installing thermal imagers for the gunner.
The RO2004 came with new Royal Ordnance dynamic armour, which was, essentially, a mix of a laminated plate and ERA, which would offer added protection from kinetic and chemical rounds. Conventional ERA would be added on top for even more protection. I would love to find some more information about the ERA, specifically what kind of protection it offers, so if anyone has anything it would be greatly appreciated!

“…Royal Ordnance patent describing the Dynamic Armor system on a conceptual level. The ERA blocks are incorporated into recesses in a cast armor body applied outside the main body of the vehicle. Each ERA block has a layer of steel in front of it, and behind it is a “shock-attenuating” material or more steel. What this means is that the ERA would be more similar to Kontakt-5 or Relikt than something like ROMOR-A, as it offers protection against both chemical and kinetic energy penetrators. Then the penetrator has to be able to go through a layer of armor and its backing material which would dissipate any fragments before it could hit and enter the hull.”

After the addition of the Challenger 2E to the British tree with the update Sky Guardians, Britain has multiple capable top-tier MBTs. However, Britain does lack in other top tier vehicles, which is why I believe this should be added as an end-of-the-line tech tree light tank, as it is in all ways better than the VFM-5. I am advocating for its implementation with thermals and all bells and whistles, alongside an optional ERA module (increased weight and protection vs increased mobility), at a potential BR of 10.3/7, given its high penetration round (very similar penetration to the CV90120’s slpprj m/95 APFSDS round but with a 105mm damage model instead of a 120mm). Not much information is around for this vehicle, but I believe Gaijin could definitely get more information that I do not have access to. Hope you agree!
