Welcome to another suggestion for a Belgian vehicle. This time we’ll be looking at Belgium’s first Leopard 1 upgrade, officially designated as Leopard SCT.

Belgium being the first export customer of the Leopard 1, had received 334 Leopard tanks, however, none of these included stabilizers or other equipment that was integrated into later built Leopard 1s. As a result, Belgium launched an upgrade program starting in 1975 to equip their Leopards with a new fire control system and stabilizer. This new system was developed by the local company SABCA and was also integrated into Australian and Canadian Leopards. The new fire control system consisted of an optical sight with a laser rangefinder and 7 sensors that measured outside temperature, air pressure, the temperature in the ammo storage, gun wear, cant, rate of turret traverse and gun wear. All of these were connected to an analog computer which would use these inputs to lay the gun and turret to the correct position for an accurate shot. On top of this, a thermal sleeve was added to the gun barrels (this made them at least a bit distinguishable from the earlier model), and storage boxes were added to the side of the hull, the latter also served as a sort of spaced armor. The upgraded model was officially designated Leopard SCT, with those letters standing for Système de Conduite de Tir, or fire control system in English. Unlike the German counterpart with similar modifications (Leopard A1A1), the Belgians chose not to add extra spaced armor on the turret at this time. Nonetheless, the vehicles continued to serve until 1990, when the next upgrade was started. The details of that will be discussed in another post, but only 132 Leopard 1BEs were selected for the upgrade, with the remaining 202 being put up for sale.

The upgrade did not have any impact on the type of gun, of course, this was still the venerable 105mm L7A3 rifled cannon. During the lifetime of the vehicle from 1975 to 1990, they were equipped with british apfsds ammo and later possibly saw the introduction of DM23 and possibly even DM33 ammunition. Coaxial armament also still consisted of the Belgian FN MAG machine gun, the same goes for the machine gun on the commander’s hatch. Mobility of the vehicle was probably pretty much unaltered by the upgrade. Some weight was most certainly added, but it is unlikely that this had any major impact on the performance.

General characteristics:

  • Crew: 4 (driver, gunner, loader, commander)
  • Weight: 40t
  • Engine: 1x MTU MB 838 CaM 500 providing 830hp
  • Length: 9.54m
  • Width: 3.37m
  • Height: 2.70m

Armament:

  • 1x 105mm L7A3 L/52 rifled cannon
    • L28A1 APDS-T — 1,478 m/s
    • L52A2 APDS-T — 1,428 m/s
    • M456A1 HEAT-T ( aka M1061 HEAT-T when produced by MECAR)- — 1,173 m/s
    • M393A2 HEP-T — 731.5 m/s
    • M416 WP-T — 731 m/s
    • L39A2 HC smoke — 259 m/s
  • 1x 7.62mm FN MAG coaxial machine gun
  • (optional) 1x 7.62mm FN MAG machine gun on commander’s hatch

Systems:

  • 2-plane stabilizer
  • Laser-rangefinder
  • Ballistics-computer

In-game:

If it were added as a researchable vehicle, then the Leopard 1BE SCT would be the logical successor of the Leopard 1BE (1968). It could be added in this manner to the proposed BeNeLux tree, or perhaps in some other manner such as a Belgian subtree in the French tree. On its own the vehicle is very similar to the German Leopard A1A1 albeit with less armor. Its slight differences could make it interesting to implement as an event/premium/squadron vehicle in the German tree as well. Gameplay-wise it will be virtually identical to the aforementioned Leopard A1A1. However, being a vehicle with a laser-rangefinder and stabilizer, it should still be enjoyable no matter what tree it is placed in.

Now this is what I’ve been waiting for on the forum: Belgian Ground Vehicle MBTs. I Love it!

Pls not in the german TT. French subtree/event or BeNeLux would be awesome though. ;)

Glad you enjoy the suggestion! More Belgian Leopard suggestions are already pending approval.

I would also prefer to see it in the BeNeLux or French tree, but as the vehicle is German of origin, I couldn’t really get around adding it as option.

Regarding the ammunition, I visited Brussels and found some fairly good Belgian documentation that can narrow this down beyond simply assuming DM23/DM33 from the Leopard’s NATO compatibility.

A 1979 Belgian Leopard SCT manual documents the ammunition load for the vehicle’s 105 mm L7 system. It lists:

  • L28A1 APDS-T — 1,478 m/s
  • L52A2 APDS-T — 1,428 m/s
  • M456A1 HEAT-T ( aka M1061 HEAT-T when produced by MECAR)- — 1,173 m/s
  • M393A2 HEP-T — 731.5 m/s
  • M416 WP-T — 731 m/s
  • L39A2 HC smoke — 259 m/s

More importantly, the manual gives an actual initial onboard allocation of 25 APDS-T, 11 HEAT-T, 20 HEP-T, 2 WP-T and 2 HC smoke rounds . The M393A2 is explicitly identified as 105 TK HEP-T WBDF , Belgian code TUEG , while the M416 is 105 TK SMK WP-T WBDF , Belgian code TUIG . The L39A2 is likewise given as 105 TK SMK HC WTF , Belgian code TUBG .

So I would be somewhat cautious about saying that the SCT “almost certainly” had DM23 and possibly DM33 without qualification. Belgium certainly had those types in its later national 105 mm inventory, and STANAG 4458 records Belgian entries for DM23A1 APFSDS-T and DM33 APFSDS-T , but the 1979 SCT documentation itself points to an earlier Belgian ammunition set centred around L28A1/L52A2 APDS-T and M456A1 HEAT-T.

There is also evidence of a later Belgian progression in 105 mm ammunition. Belgian/MECAR-associated ammunition includes M1001 APFSDS-T, M1010 HE-T, M1050 APFSDS-T, M1060 APFSDS-T and M1061 HEAT-T , in addition to the M393A2 and M416. The CIA specifically identifies M1050 and M1060 as ammunition for L7 guns.
