The 10.5 cm SK L/45 (Schnelladekanone Länge 45, quick-loading cannon with a barrel length of 45 calibers) was a German naval gun that was used in World War I and World War II and was the successor of the older 10.5 cm SK L/40 naval gun.

Description

The 10.5 cm SK L/45 gun weighed 1,450 kilograms (3,200 lb), had an overall length of 472.5 cm (15 ft 6 in). It used a horizontal sliding-block breech design. Cradle is usually mounted on a conical pedestal mount, bolted to the submarine deck.

The guns were carefully designed according to the requirements of submarine operations and was therefore streamlined in design. Many items manufactured from brass to resist corrosion.[2]

It was used on many German and foreign ships like SMS Mowe and Ottomon cruiser Midilli.
