mittlerer Zugkraftwagen 8t (Sd. Kfz. 7) - middle half-track vehicle 8 tons

 

 

 

 

 

The development of the m. Zgkw. 8t was started by Krauss Maffei in 1932. The type Km m 8 (Daimler Benz DB m 8, Büssing-NAG BN m 8) was manufactured in 1934/35. It had a total weight of 11 tons and a 115 HP engine. Characteristic for these early vehicles was the old-fashioned radiator mask and the short track drive assembly.
The successors models Km m 9 and Km m 10 and/or HL m 10 (Hansa Lloyd) were manufactured from 1935 to 1937. Still, these vehicles had a short track drive assembly but a newer radiator mask. They only differed by the used engines and the used steering systems. In 1937, the conclusion model Km m 11 was introduced. The track drive assembly had been extended and the style of the fenders had been revised. Until the year 1945, approximately 12,000 vehicles were manufactured.
The predominant part of these vehicles was equipped with an artillery superstructure and was used as towing vehicles for middle class guns. The final execution of the m. Zgkw. 8t had a simple platform made of wood in place of the artillery superstructure.
The Selbstfahrlafette (Sd. Kfz. 7/1) für 2cm Flakvierling 38 and the Selbstfahrlafette (Sd. Kfz. 7/2) für 3.7cm Flak 36 were used as self-propelled anti aircraft guns. Later, these vehicles got an armoured driver's cab and armour plates in front of the radiator. The final model of these selfpropelled anti aircraft guns had dropsides made of wood instead of the metal ones. The Flak Messtruppkraftwagen (Sd. Kfz. 7/6) - an anti aircraft survey party vehicle - had an extended stowage box at the rear. Some of the Sd. Kfz. 7 were armoured. They were used as towing vehicles for the 8,8cm Bunkerflak during the France campaign. There were several partly-armoured Sd. Kfz. 7 used as fire control vehicles for the V-2 long distance rocket units as well as experimental models of a self-propelled anti aircraft gun armed with a 5cm Flak 41.
199 m. Zgkw. 8t were manufactured under license - with minor changes - by BREDA in Italy. Less known was the attempt of the British to copy the m. Zgkw. 8t. A testing vehicle was produced by Vauxhall Motors. The end of war terminated these attempts.
