Английская Википедия:15 cm SK C/28
The 15 cm SK C/28[Note 1] was a German medium-caliber naval gun used during the Second World War. It served as the secondary armament for the Шаблон:Sclass and Шаблон:Sclasss, Шаблон:Sclasss and the Шаблон:Sclasss. A number of surplus weapons were used as coast-defense guns and eight were adapted to use Army carriages and used as heavy field guns as the 15 cm Schiffskanone C/28 in Mörserlafette
Description
This gun was designed as a smaller and lighter version of the 15 cm SK C/25 guns used as the main armament of the Шаблон:Sclass- and Шаблон:Sclasss. It shared the earlier gun's design with a loose barrel, jacket and breech-piece with a vertical sliding breech block.[1]
The Drh. LC/34 twin-gun mount was the most common mount for the gun in the Kriegsmarine. It was used as the secondary armament of the Шаблон:Sclass and Шаблон:Sclasss and was planned to equip the proposed H-class battleships. The mount weighed between Шаблон:Convert, depending on its armor thickness; the Scharnhorst's mounts had between Шаблон:Convert of armor while the Bismarck's had Шаблон:Convert. Maximum elevation was 40°, giving a range of Шаблон:Convert and maximum depression was -10°, while maximum elevating speed was 8° per second. Each mount was designed for full 360° of traverse, but was limited to much less than that by the ship's superstructure. Speed in train was a maximum of 9° per second. The fastest firing cycle was 7.5 seconds, or 8 rounds per minute. Ammunition was supplied by twin hoists between the guns, at the rear of the mount. The Шаблон:Sclass2 was intended to use a lighter version of this mount with thinner armor that only weighed approximately Шаблон:Convert. This may have designated as the Drh. LC/40, but development ceased when the ships were canceled in 1939.[1][2]
Шаблон:Ship and Шаблон:Ship also carried four single MPL C/35 mounts that weighed Шаблон:Convert with armor between Шаблон:Convert thick. Each mount could depress -10° and elevate to 35°; this gave a maximum range of Шаблон:Convert. The MPL C/28 mount used in the Шаблон:Sclasss was virtually identical to the newer mount except its gun shield was smaller so it weighed only Шаблон:Convert.[1]
The Шаблон:Sclasss were going to carry eight twin-gun Dopp MPL C/36 casemate mountings. These weighed Шаблон:Convert and had an armored shield Шаблон:Convert thick. The mount elevated at a speed of 6° per second and trained at a rate of 8° per second.[1]
Coast defense mountings
The Küsten-Marinepivotlafette (Küst. MPL C/36) was a highly successful mobile coast defense mount fitted with a gun shield. The gun traversed on a six-legged firing platform that allowed 360° of traverse. It could depress -7° and elevate to a maximum of 47° 30', which gave it a range of Шаблон:Convert. The gun on its carriage weighed Шаблон:Convert. It was towed via two two-axle trailers, one at each end. For travel the four lateral legs of the platform folded vertically. It entered service in 1940.[3]
Army mount
Production of carriages for the 21 cm Mörser 18 and the 17 cm Kanone 18 in Mörserlafette exceeded the available number of barrels in 1941 and eight SK C/28 barrels were adapted for use on the carriages as the 15 cm Schiffskanone C/28 in Mörserlafette. They were converted to Heer-standard percussion firing. Most guns were replaced by Шаблон:Convert barrels as they became available, but one battery retained them through the beginning of the Battle of Kursk in July 1943.[4]
Ammunition
The SK C/28 used several different shells depending on its target. The 15 cm Sprgr L/4.6 KZ m Hb weighed Шаблон:Convert and had a muzzle velocity of Шаблон:Convert. It was a nose-fused HE shell with ballistic cap with two copper driving band and a lead ring behind them to act as a decoppering device by scraping away any copper residue from the driving band. The 15 cm Sprgr L/4.5 Bd Z m. Hb was a base-fused shell with a ballistic cap and weighed Шаблон:Convert. It was roughly equivalent to the British "Common Pointed" and also used a lead decoppering ring. The armor-piercing 15 cm Pzgr L/3.8 m Hb shell had a ballistic cap and weighed Шаблон:Convert. All shells used Шаблон:Convert of propellant in an artificial silk bag, housed in a brass cartridge case.[5] An illumination shell was also available, although details are unknown.[1]
History
Surplus naval mountings were used to reinforce German coast defenses from Norway to the French Atlantic coast. These included guns from incomplete or disarmed ships like the aircraft carrier Шаблон:Ship or the battleship Шаблон:Ship. For example, three or four of the Graf ZeppelinШаблон:'s Dopp MPL C/36 mounts equipped both batteries of Naval Artillery Battalion (Marine-Artillerie-Abteilung) 517 at Cap Romanov near Petsamo, Finland[6][7] while two of the GneisenauШаблон:'s Drh. LC/34 mounts were emplaced on the west coast of Denmark at Esbjerg where they equipped Batterie Gneisenau of Naval Artillery Battalion 518.[8] All told, a total of 111 SK C/28 guns were employed on coast defense duties in a variety of mounts, 28 in Norway, 12 in Denmark, 24 in the German Bight, 8 in the Netherlands, and 39 in Belgium and the Atlantic coast of France.[9]
Surviving guns in Norway and Denmark were used throughout the Cold War by both countries.[2]
