David Lehmann -> 1939/1940 French tanks AT performance (10/1/2003 7:09:46 PM)

Hello,
I am just wondering about the poor AT capabilities of the French tanks in SPWAW. The best tank AT gun in 1939/1940 on the French battlefield seems to be the German 37mm which is wrong. For many reasons (1-man turret ...) the German tanks might be slightly better but the 47mm guns by themselves are really better on the French side.
In SPWAW the PzIIIe has a MAXIMUM penetration of 64mm and the Somua S-35 only 57mm with the 47mm SA35 L34 (1598mm barrel) which is the best tank gun in 1940 (present on the Somua S-35, the B1bis turret and the AMC-35 for example). It penetrates 40mm /30° at 400m et 60mm /0° at 1000 m. How is then considered the MAX penetration at 1 hex range ?
This gun should not be mixed up with the 47mm SA34 L30 (shorter barrel of 1410mm) present in the turret of the B1 tank for example.
Among infantry weapons the by far best AT gun is the 47mm Mle37 L50 (2350mm barrel). And I am not even talking about the 75mm Mle1897 used in an AT role. The basic artillery Mle1897 was sometimes used but you could also find the 75mm Mle97/33 and Mle97/35 dedicated to the AT role in the BDAC (= Batterie Divisionaire anti-char = AT divisional battery for the protection of an artillery regiment). Many were still in service in the BDACs since there was a lack of 47mm AT guns to equipe all units.
Germans had 1-man turrets for their PzI and PzII (except the late war model (Luchs) with 2 men). The PzIII and PzIV had 3 men in the turret. The British Matilda I also had a 1-man turret.
On the French side all of the tanks and armored cars had a 1-man turret except :
- FCM 2C (11 men with 3 in the front turret and 1 in a rear turret)
- Laffly AM50
- Panhard 165/175
- Panhard 178
- Renault AMC-35
- And actually the SOMUA S-35's APX4CE turret is sometimes described as a "one-and-a-half-man turret", as the enlarged turret ring, compared with the APX1 found on the B1bis, allowed a crew member to provide "some" assistance to the commander/gunner/reloader.
The quality of French tank optics were not at all inferior to the German ones, this is a false statement. In fact they were of similar quality, perhaps a bit more complicated to operate.
Another surprising and common statement is about intrinsec accuracy of French guns versus German ones. Accuracy is not a matter of nationality, but only a matter of ballistics ... and all the ballistics tests I am aware of proved that the guns were very accurate. French tank guns like 47mm SA35 were superior to any German tank armament fielded in 1940. Some French tankers scored very well, others not so well. This was due to training, one-man turret etc. but the guns by themselves were totally good ones.
