The 38 cm SK L/45 "Max", also called Langer Max was a German long-range, heavy siege and coast-defense gun used during World War I. Originally a naval gun, it was also adapted for land service when it became clear that some of the ships for which it was intended would be delayed and that it would be very useful on the Western Front.
