History edit

In 1886, Krupp designed the 21 cm L/35 and started production for export customers in 1890. The 21 cm L/35 was produced in two models the No. 1 and No. 2. The main difference between the two guns was their weight, rifling, propellant charges and muzzle velocities. Otherwise their overall length and ammunition were the same.[3]

The 21 cm came in different variants:[4]

  • Model 1880: L25, L30, L35
  • Model 1887: L35, L40
  • Model 1889: L40, L50
