In early 1942 Wa.Prüf 4, the German organization in charge of field artillery, put forward a design requirement for a vehicle to move heavy artillery. The main stipulation was that it should use parts from the new Panther medium tank. A similar competition was already underway for a vehicle to move lighter field artillery, such as 10,5cm guns, using the Geschützwagen III/IV chassis. This had inspired Wa.Prüf 4 to do the same for a vehicle to move heavier 12,8cm and 15cm artillery pieces, as the Geschützwagen III/IV was too small to handle them. The guns in question were the 12,8cm K 43 and 15cm sFH 43. The sFH 43 was a projected improvement on the 15cm sFH 18, the new gun was to use bagged propellant and had a screw-type breech. The 12,8cm K 43 is unknown in most literature, but is presumably a predecessor to the 12,8cm K 44 L/55. Neither of these cannons were ever built.

In order to keep weight down, the designs were to be open-topped. Prototypes were to be built using Panther parts, but it was projected that any serial production vehicles would be made using the Panther II chassis. This idea was discarded when the Panther II was cancelled in June of 1943.

Both Krupp and Rheinmetall-Borsig took part in this design competition. All designs were able to be transported by rail with a few adjustments; and all could carry at least 30 rounds of ammunition, however Rheinmetall’s design had trouble with this.

Rheinmetall-Borsig's final entry for the Selbstfahrlafette für 12,8cm K 43 und 15cm sFH 43 Project.

On April 16th Rheinmetall produced drawing H-SKA 82566 for the 15cm sFH 18 mit Panther Bauteilen as a counterpart to the 12,8cm Skorpion mit Panther Bauteilen, from drawing H-SKA 81959 from April 2nd, 1943. These designs had a Panther-based chassis with a wheelbase of 4,025mm. These designs were known by their project cover name of Skorpion. Further details unknown.

On October 20th, 1943, Wa.Prüf 4 cancelled the Grille, Heuschrecke, and Skorpion projects.
