German Balkenkreuz

Germany's BW/7; Panzerkampfwagen IV Ausf F1; PzKpfw IV Ausf F1; SdKfz 161; medium tank

Design

Original order was for 500 to be built by Krupp-Gruson. This was increased when Vomag received an order for 100 and Nibelungenwerke for 25. Before these were all completed the OKH ordered that the rest of the order have 7.5 cm KwK 40 L/43 installed as soon as possible and a total of 25 were converted to PzKpfw IV Ausf F2s.

A single plate of armor extended across the front of the superstructure.7,9 The revolver port in the front was replaced by a Kugelblende 50 (ball mounting) with a machine gun installed.7,9

In the PzKpfw IV Ausf F1 the driver had a Fahrersehklappe 50 (visor) to look out.7,9

The maintenance hatches in the glacis plate had air intake apertures installed in each door with a welded cast cowling protecting them.7,9

The turret had the single door replaced by a double door with the front door having a vision port and the rear door having a pistol port.7,9

Used a TZF 5f telescope that was mounted to the left of the main gun.6

The AP round of the 75 mm gun weighed 15 lbs and had a muzzle velocity of 1,263'/sec.3

The driving sprocket had the spokes bent outwards.7,9 The rear idler was constructed from 2.25" welded tubes.7,9 There were flat plates that were welded to the inside and outside sections.7,9

The first 20 PzKpfw IV Ausf Fs left the factory in February 1940.7,9
