The 20.3 cm/45 Type 41 naval gun (ingame as the 41st Year Type) was a Japanese naval artillery and coastal defense gun used on cruisers of the Imperial Japanese Navy from the end of the Russo-Japanese War through the end of World War II.
It is one of the more powerful coastal guns but like the German 15 cm Torpedobootskanone C/36 the operator is quite exposed to attacks, unlike the generic Defgun where the gunner is shielded inside.
