40.6 cm Schnelladekanone

The 40.6 cm Schnelladekanone C/34 (40.6 cm SK C/34), sometimes known as the Adolfkanone, was a German naval gun, designed in 1934 by Krupp and originally intended for the early H-class battleships.

Intended to be mounted in battleship turrets, the guns were produced in left and right-handed pairs. These pairs were split for individual mounting in the coastal defence role. The gun's barrel was approximately 20 metres (66 ft) long (sources state between 20,300 and 21,130 millimetres (800 and 832 in)). In a coastal defence emplacement the gun could be elevated to 52 degrees, giving it a range of 56 kilometres (35 mi) with the special 600 kilograms (1,300 lb) long range shell called the Adolf-shell. In terms of construction the 40.6 centimetres (16.0 in) guns were identical to the 38 cm SK C/34 - only the calibre of the barrel was different. The rate of fire for the weapon was around 2 minutes per round as coastal artillery.

The Schleswig Holstein Battery from Hel, (German unit MKB 2 / MAA 119) in France recalled as Battery Lindemann (German unit MKB 6 / MAA 244) saw considerable service, with the three guns emplaced singly in turrets, protected by massive concrete encasements in places four metres thick. The guns fired 2,226 shells at Dover between 1940 and 1944. The guns were not put out of action by bombing despite being hit many times, due to the thick concrete. Only the Bruno turret was damaged on 3 September 1944, when a shell from a British Railway Gun hit its elevating gear shortly before the battery was captured.
