German Balkenkreuz

Germany's 4/ZW; Panzerkampfwagen III Ausf E; PzKpfw III Ausf E medium tank

Design

The PzKpfw III Ausf E was the last of the pre-production series.

These were still on troop trial on September 1, 1939. A few had the 50 mm L/42 gun installed with covers on air intakes.

Turret

Early models had the pre-production turrets that had two machine guns coaxially. New improvements were a two part visor for the driver, and the single door in the side of the turret was replaced by a double door with vision slots and pistol ports.

Suspension

The suspension was redesigned with six independent bogie road wheels, suspended from torsion bars. New suspension with individually supported road wheels.

Transmission

Had a new transmission and more powerful engine. The transmission was rather complicated but it was intended to make gear changing easier. The 9th and 10th gears were overdrive.

Production

The PzKpfw III series production figures.

  • Chassis Numbers: 60401 - 60441

Usage

98 of the PzKpfw III Ausf Es were used in Poland, and 350 in France.
