Please ladies contain your spasms, have some screenshots for you and updated stats of the Grille 15(Waffentrager auf E 100 replacement, its not yet clear whether is coming next patch):
By the summer of 1942, the German land forces command made a contract with the companies Krupp and Rheinmetall to create a SPG on the Panther hull. Several variants with 128mm K43 gun and 15cm sFH 43 howitzer were considered. These projects were called Grille 12 and Grille 15. Their armament was located in the back of the vehicle and they were different from each other only by the type of the gun. Later on, requirements were issued to install the 15cm L/63 gun on Grille 15 chassis. This gun could penetrate 200mm of armor at 4000 meters. The project was however stopped and no prototype was built.
1942年的夏天，德国陆军和克虏伯以及莱茵金属公司签了一份合同，要求他们在豹式的底盘上造出一个自走火炮来。他们曾经造出过用128mm K43炮和用15cm sFH 43榴弹炮的两个版本，分别叫做蟋蟀12和蟋蟀15。这两辆车的主炮都在车身后方，而这两种车唯一的差距就只是主炮而已。后来军方的要求变成了在蟋蟀15的底盘上安装15cm L/63炮。这杆炮可以在4000米的距离上击穿200mm的装甲。然而这个计划最后被终止了，也没有原型车被造了出来。
