Later they were adapted for land service during World War I and World War II. Description The 17 cm SK L/40 gun although designated as 17 cm us, its actual caliber was 17.26 cm us. It used the Krupp horizontal sliding-block, or "wedge", as it is sometimes referred to, in a breech loading design, rather than the interrupted screw commonly used in the heavy guns of other nations. This required that the propellant charge be loaded in a metal, (usually brass), case which provides obturation, i.e. seals the breech to prevent escape of the expanding propellant gas. Naval Use The Braunschweig-class secondary battery consisted of fourteen 17 cm SK L/40 quick-firing guns, four of which were mounted in single turrets amidships, with the remaining ten in casemates around the superstructure. These guns had a total of 1,820 shells, for 130 rounds per gun and a rate of fire of approximately 6 per minute. To transit the Kiel Canal, the three central casemated guns had to be withdrawn into their housings, as they were unable to train fully flush with the sides of the ships. With the guns fully emplaced, the ships would have been too wide to fit in the canal.Gröner 1990 20 The Deutschland-class secondary battery consisted of fourteen 17 cm SK L/40 quick-firing guns mounted in casemates amidships. Five were emplaced in the top deck and two one deck higher in the superstructure on either side. These guns had a total of 1,820 shells, for 130 rounds per gun and a rate of fire of approximately 6 per minute. The guns had an arc of train of 160°.Germany 17 cm/40 (6.75") SK L/40 http://www.navweaps.com/Weapons/WNGER_675-40_skc04.php Navweaps.com 10 May 2020 World War I Field Gun When the pre-dreadnoughts began to be relegated to training duties in 1916.François 2006 40 The guns were adapted for land use by mounting it on an improvised carriage, but this proved to be extremely heavy, often too heavy to be moved by horse, even after being broken down into three loads. The solution was to mount the guns, still on their carriages, on rail cars to increase their strategic mobility.http://www.landships.freeservers.com/17cm_schnelladekanone_ir.htm German 17cm Schnelladekanone i.R.
