The 38 cm Siegfried K (E) (K - Kanone (cannon), E - in Eisenbahnlafette (on railroad mounting)) was a German World War II railway gun based on the 38 cm SK C/34 naval gun that served as the main armament of the s. Only four were produced. ==Design== Like the 38 cm SK C/34 naval guns deployed as coastal defense, the 38 cm Siegfried K guns were modified with a larger chamber to handle the increased amount of propellant used for the special long-range ''Siegfried'' shells.〔38 cm/52 (14.96") SK C/34, NavWeaps () Chamber volume increased from 19,467 in3 (319 dm3) to 22,072 in3 (361.7 dm3), rifling length reduced correspondingly from 629.2 in. (15.982 m) to 620 in (15.748 m)〕〔Campbell, p. 229〕 The gun had no ability to traverse on its mount, relying instead on moving along a curving section of track or on a Vögele turntable to aim. The turntable (''Drehscheibe'') consisted of a circular track with a pivot mount in the center for a platform on which the railroad gun itself was secured. A ramp was used to raise the railway gun to the level of the platform. The platform had rollers at each end which rested on the circular rail for 360° traverse. It had a capacity of , enough for most of the railroad guns in the German inventory. The gun could only be loaded at 0° elevation and so had to be re-aimed for each shot.〔François, p. 75〕 ==Ammunition== It used the standard German naval system of ammunition where the base charge was held in a metallic cartridge case and supplemented by another charge in a silk bag which was rammed first. Four types of shells were used by the ''38 cm Siegfried K (E)'', including the special long-range ''Siegfried shell (Siegfried—Granate'') developed by the army. Almost 40 per-cent lighter, it could be fired with a reduced charge at to . With a full charge it reached and could travel –equivalent to over 34.5 miles.〔Hogg, pp. 242-3〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「38 cm Siegfried K (E)」の詳細全文を読む スポンサード リンク
