A counterpart to the heavy German “Bertha” howitzers, the 305mm “Emma” howitzer was adopted in 1913 and achieved a 13,123-yard maximum range with an 838-pound shell. The 280mm howitzer was accepted the following year and fired a 745-pound shell up to 12,030 yards. In 1916, Austria introduced both the 305mm Howitzer M16, with a maximum range of 32,808 yards with a 1,543- pound shell, and the 380mm Howitzer M16, which fired a massive 2,205-pound shell to a maximum range of 16,404 yards. These weapons were followed in 1917 by the nearly 117-ton, 420mm L/15 Howitzer, firing a 2,205-pound shell up to 15,967 yards.
