The 15 cm SchiffsKanone C/28 in Mörserlafette (SK C/28 in Mrs Laf) was a German heavy gun used in the Second World War.
Development
[edit]Production of carriages for the 21 cm Mörser 18 and the 17 cm Kanone 18 in Mörserlafette exceeded available barrels in 1941 and eight naval 15 cm SK C/28 coast defense gun barrels were adapted for use on the carriages. They were converted to Heer-standard percussion firing (see the articles of those guns for details on the design of the carriage).
Operational use
[edit]For Operation Barbarossa (the invasion of the Soviet Union), it equipped Artillerie-Abteilung 625.[1] Most guns were replaced by 17 cm barrels as they became available. However, for Case Blue (the German summer offensive in southern Russia), one battery of Artillery Battalion (Artillerie-Abteilung) 767 was still equipped with them.[2] That same battery retained them through the beginning of the Battle of Kursk in July 1943.[3]
Ammunition
[edit]The 15 cm SK C/28 in Mrs Laf could not be converted to use the Heer's standard 15 cm ammunition and had to use naval ammunition. These included the 15 cm Sprgr L/4.6 KZ m. Hb., the 15cm Sprgr L/4.5 BdZ m. Hb. and the 15 cm Pzgr L/3.8 m. Hb. The former was a nose-fuzed 45.5 kilograms (100 lb) HE shell with a ballistic cap. The second was a base-fuzed 44.8 kilograms (99 lb) HE shell, also with a ballistic cap. The last-named was a standard 45.3 kilograms (100 lb) armor-piercing shell. Only one 14.1 kilograms (31 lb) bag of propellant was used in a separate-loading cartridge case.
