The 15 cm Ring Kanone L/22 or Kurze 15 cm Ring Kanone was a 15 cm 22 caliber long Krupp Ring Kanone (RK). It was a rifled breech loader built-up gun with a Krupp cylindroprismatic sliding breech. It was designed based on the idea that for penetrating armor, it was more effective to increase the charge than to increase the caliber. There were two models: The original model with 24 wedge grooves and the later model with 36 parallel grooves.^[2]
