History

Devblog

By 1942, German engineers recognized the need of the Wehrmacht for a light SPAAG to provide cover for frontline troops against low flying aircraft and set about developing a suitable vehicle on the chassis of available halftrack designs. In 1943, this need became even more emphasized with limited German production capacities being unable to produce the required number of Flakpanzers that the Wehrmacht had been requesting.

Subsequently, German engineers decided to outfit the widely used Sd.Kfz. 251 halftrack with a three-barrel AA mount, initially equipped with 15 mm, later with 20 mm cannons, in order to meet the Wehrmacht’s demand. The new modification became known as the Sd.Kfz 251/21 and went into production in 1944.

By the time the Sd.Kfz. 251/21 entered service, troops more widely used it as a support vehicle in the late stages of the war, with the vehicle performing well in this role. Nonetheless, over 380 units of the Sd.Kfz. 251/21 were produced until the end of the war, many of which through conversion of older modifications.
