Vorlage:Infobox weapon The Royal Cannon Foundry 47mm anti-tank gun Model 1931 (Vorlage:Lang-fr, abbreviated to C.47 F.R.C. Mod.31) was an artillery piece developed in 1931 for the Belgian army which saw widespread service in the Battle of Belgium in 1940. It was colloquially known as the "'Quat'sept", after its Vorlage:Convert caliber, by the Belgian soldiers that used it.

It was developed by the firm F.R.C., the Herstal-based Fonderie Royale de Canons, not to be confused with the French F.R.C.

Versions

Both infantry and light troops (cavalry units, cyclist units,...) versions of the gun were produced with minor variations: the light troops version had pneumatic tires for greater road mobility, while the infantry versions had heavier but more durable full-rubber tires. The gun was also able to be incorporated into fixed defences and bunkers, including the Belgian fortifications at the Albert Canal. They were also fixed to the T-13 tank destroyer and the 'Canon antichar automoteur Vickers-Carden-Loyd Mk.VI'.

Performance

Regarding its time of development, the '47' had an impressive performance, especially in comparison to contemporary German or French designs – respectively the 3.7 cm Pak 36 and 25 mm Hotchkiss anti-tank gun. In medium range armor penetration it even outperformed the British Ordnance QF 2-pounder: armor-piercing rounds could penetrate Vorlage:Convert of armored steel at a range of Vorlage:Convert. This was largely due to the heavy caliber with a shell weight of Vorlage:Convert for the armor-piercing rounds. However, this performance came at a price: with a total weight of Vorlage:Convert, not including ammo or equipment, the 47 mm was a lot heavier than the German Pak 36 (at Vorlage:Convert) although, with a compact design, the 47 mm was easier to conceal. Repositioning was aided by Vickers Utility B armoured tractors in infantry divisions or the Ford Marmon Herrington armoured tractor in cavalry units.

Service history

Second World War

Belgium

Over 750 47 mm guns were in service in the Belgian army at the time of the German invasion in 1940. All active and first reserve infantry units, cavalry units and units of the border guards were equipped with the gun, while the second reserve units had to make do with older anti-tank rifles. Every infantry regiment consisted of 3 battalions of rifle infantry and a single heavy arms battalion. This in turn consisted of three heavy weapon companies, one of which was equipped with 12 47 mm guns. Given its good armor penetrating capabilities, the 47 mm could penetrate the armor of the German Panzer III and Panzer IV tanks from a range of over Vorlage:Convert. Reports of panzers knocked out by the 47 mm during the Battle of Belgium do exist, but in general the bulk of the Belgian army was deployed in the north of the country, on the flat terrain of Flanders, and not in the hilly terrain of the Ardennes in the south, which was regarded as impenetrable but nonetheless served as the primary route of invasion for about 2,500 German panzers.

Germany

The German designation for captured guns was the 4.7 cm Pak 185(b). A few were installed in Atlantic Wall defenses in Belgium and the Channel Islands.

Hungary

Several hundred 47 mm guns were captured by the Germans after the battle of Belgium and donated to the Hungarians in 1940-1, to make up for their lack in anti-tank guns during Operation Barbarossa. Their use was limited however due to a lack of spare parts, while the armor penetrating capabilities of these guns had also been surpassed by the Soviet advances in tank construction. Most were relegated to training duties.
