The 24 cm MRK L/25.5 was a Krupp prototype naval gun developed in the late 1870s. It was one of two guns that Krupp made to test the application of scientific discoveries with regard to gunpowder. These discoveries made it possible to use higher charges by enlarging the chamber of the gun. During an August 1879 test in Meppen, the gun pierced 51 cm of armor. This test prompted the last competitors to switch to steel guns and breech loading.
