Question: How many guns could the battleship for the Imperial German Navy, which was the fourth pre-dreadnought and replaced ironclad battleships of 1870s and 1880s, carry?

<P0-S0> Pre-dreadnought battleships were sea-going battleships built between the mid- to late 1880s and 1905, before the launch of HMS "Dreadnought" . <P0-S1>  Built from steel, and protected by hardened steel armour, pre-dreadnought battleships carried a main battery of very heavy guns in barbettes (open or with armoured gunhouses) supported by one or more secondary batteries of lighter weapons. <P0-S2>  They were powered by coal-fuelled triple-expansion steam engines. <P0-S3>  Pre-dreadnoughts replaced the ironclad battleships of the 1870s and 1880s. <SEP> <P1-S0> In the 1880s, Germany built a series of coastal defense ships to protect its coastline on the North and Baltic Seas. <P1-S1>  During the 1870s and early 1880s, the Imperial German Navy had built a number of ironclad warships of various designs. <P1-S2>  In the mid-1880s, however, dissatisfaction with the "Sachsen"-class ironclad s and the rise of the "Jeune École" doctrine persuaded Leo von Caprivi, then the chief of the Imperial Navy to turn away from capital ship construction in favor of coastal defense ships and torpedo boats. <P1-S3>  As a result, the next class of large warships, the "Siegfried" class , was significantly smaller than the earlier ironclads, and armed with a main battery of only three large-caliber guns. <P1-S4>  These vessels were intended only for defense of German harbors. <P1-S5>  Six of them were built between 1888 and 1894. <P1-S6>  Another two ships of the "Odin" class were built to a modified design between 1892 and 1896. <SEP> <P2-S0> The "Deutschland" class was a group of five pre-dreadnought battleships built for the German Kaiserliche Marine. <P2-S1>  The class comprised "Deutschland" , "Hannover" , "Pommern" , "Schlesien" , and "Schleswig-Holstein" . <P2-S2>  Built between 1903 and 1908, the ships closely resembled those of the preceding "Braunschweig" class , though they had stronger armor protection. <P2-S3>  They were made obsolete before they were even completed by the launch of the revolutionary Royal Navy battleship HMS "Dreadnought" in 1906. <P2-S4>  As a result, they were the last ships of that type built for the German Navy. <P2-S5>  They were followed by the "Nassau"-class battleship s, Germany's first dreadnought battleships. <SEP> <P3-S0>  The ship was named for Prince-elector ("Kurfürst") Friedrich Wilhelm, 17th-century Duke of Prussia and Margrave of Brandenburg. <P3-S1>  She was the fourth pre-dreadnought of the "Brandenburg" class , along with her sister ships "Brandenburg" , "Weissenburg" , and "Wörth" . <P3-S2>  She was laid down in 1890 in the Imperial Dockyard in Wilhelmshaven, launched in 1891, and completed in 1893 at a cost of 11.23 million marks. <P3-S3> SMS "Kurfürst Friedrich Wilhelm" ("His Majesty's Ship Elector Friedrich Wilhelm") was one of the first ocean-going battleships of the Imperial German Navy. <P3-S4>  The "Brandenburg"-class battleships carried six large-caliber guns in three twin turrets, as opposed to four guns in two turrets, as was the standard in other navies.
