The 15 cm Mantel Ring Kanone L/30, known as 15 cm Kanone L/30 was a 15 cm 30 caliber long Krupp Mantel Ring Kanone (MRK). It was a rifled breech loader built-up gun with a Krupp cylindroprismatic sliding breech. It was based on the later models of the 15 cm RK L/26, a 15 cm MRK L/28, and a 15.24 cm (6 inch) predecessor. This predecessor was the first of a new series of 30 and 35 caliber long guns that Krupp made to profit from a slower burning gunpowder invented in the early 1870s.
