42 cm Gamma Mörser

The 42 cm kurze Marinekanone L/12, or Gamma-Gerät, was a German siege gun built by Krupp. The Gamma-Gerät's barrel diameter was 42 cm (17 in), making it one of the largest artillery pieces ever fielded. The Gamma-Gerät began development in 1906 and entered service with the Imperial German Army in 1911. The Gamma-Gerät was the most powerful piece of artillery fielded by the Imperial German Army, but due to its extreme weight was mostly immobile and could only be emplaced near permanent rail lines. As a result, the Gamma-Gerät had limited effectiveness on the Western and Eastern Fronts of World War I.
