History
History
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. The 21 cm came in different variants: • Model 1880: L25, L30, L35 • Model 1887: L35, L40 • Model 1889: L40, L50
