Panzer III Ausf L (SdKfz 141/1)
Type: Medium tank.

History:

In March 1942, a study was undertaken to determine whether the Panzer IV turret would fit on the Panzer III superstructure. Analysis revealed that the resultant weight was excessive, and numerous modifications would be necessary. The idea was dropped, and production of the Panzer III with the 5cm KwK39 L/60 continued.

The original order for 1,100 Ausf L was reduced by an order, early in June 1942, to mount 450 7.5cm KwK L/24 in the Panzer III. 447 Ausf L were used to mount the short 7.5cm gun and thus became Ausf N. One Ausf L was completed with an experimental, tapered-bore KwK0725.

Improvements to the Ausf L included increasing the armour on the turret front from 30mm to 57mm, installing a torsion-bar counter-balance instead of a coil spring for the main gun, and altering the air-instake louvres and hatches on the rear deck. All Ausf L had 20mm spaced armour on the superstructure front, and most had 20mm spaced armour on the gun mantlet. Early in the production run, the hull escape hatches on the hull side, the loader’s vision port on the gun mantlet and the turret side ports were deleted. A system designed to transfer heated engine coolant from one vehicle to another was also introduced with the Ausf L.

From late in June 1942, at the start of the summer offensive in Russia, there were approximately 600 Panzer III mounting the 5cm KwK L/60 with units at the front in Russia. Apart from replacing losses, Ausf L were issued to the newly-formed Panzer regiments of the 1st SS-Division Leibstandarte Adolf Hitler, 2nd SS-Division Das Reich and 3rd SS-Division Totenkopf (all now Panzergrenadier divisions), and the Panzergrenadier Division Grossdeutschland.

Users: Germany, Hungary, Spain, Turkey (for all variants).
