由于广受好评的四号坦克歼击车(V型)产能不足,并且四号坦克无法安装更长身管的火炮,德国军方开始研发一种大体基于四号坦克底盘的坦克歼击车。考虑到战斗室下方油箱的位置,直接将“四歼”的上车体安装到四号坦克底盘上是非常困难的。阿尔卡特公司设计了一种大型钢装甲战斗室,这就衍生出四号坦克歼击车(A型)。这种设计的目的是为了在位于奥地利的工厂能够生产具有低矮外形的沃马格型“四歼”之前,研发一种过渡 Due to the under-production of the critically acclaimed No. 4 tank destroyer (V-Type) and the inability of the No. 4 tank to install longer-barrel guns, the German military started to develop a tank destroyer based largely on the No. 4 tank chassis. Taking into account the tank below the fighting room position, directly to the “four annihilate” on the body to install the fourth tank chassis is very difficult. Alcatel has designed a large steel armored fighting room, which is derived from the Fourth Tank Destroyer (Type A). The purpose of this design was to develop a transition before the Austrian factory was able to produce a low-profile Wmagma type
