Historic and technical information

Origin :

Krupp)

Historic context :
Designed by KRUPP in 1892 as a fortress heavy gun dedicated to fire over the parapets, on the base of the older 15 cm RK 72, the 'lange 15 cm R K 92' ('RK' = 'Ring Kanone') was an old-fashioned weapon that did not have a quick-action breech nor any kind of recoil recuperator system. Moreover, its 'Ring Kanone' name indicated that the tube was produce by binding of different diameters steel tubes, a technique that was later replaced by steel forging.
This gun was therefore obsolete in 1914, but this did not prevent ihe German Army to extract the existing guns from their arsenals and fortresses to use them on the different fronts during several years, bringing a solution to the lack of heavy guns.
