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?

Context paragraphs:
24 cm K L/35: The 24 cm K L/35 was a German Naval Gun developed in the years before World War I that armed ships of the Imperial German Navy, Argentine Navy and the Austro-Hungarian Navy.  Guns removed from ships of the Imperial German Navy were modified to perform Coastal Artillery and Railway Artillery roles and saw service in both world wars.  The actual bore diameter was 23.8 cm , but the classification system for artillery rounded up to the next highest centimeter.

SMS Weissenburg: SMS "Weissenburg" was one of the first ocean-going battleships of the Imperial German Navy.  She was the third pre-dreadnought of the "Brandenburg" class , which also included her sister ships "Brandenburg" , "Wörth" , and "Kurfürst Friedrich Wilhelm" .  "Weissenburg" was laid down in 1890 in the AG Vulcan dockyard in Stettin, launched in 1891, and completed in 1894.  The "Brandenburg"-class battleships were unique for their era in that they carried six large-caliber guns in three twin turrets, as opposed to four guns in two turrets, as was the standard in other navies.

SMS Kurfürst Friedrich Wilhelm: SMS "Kurfürst Friedrich Wilhelm" ("His Majesty's Ship Elector Friedrich Wilhelm") was one of the first ocean-going battleships of the Imperial German Navy.  The ship was named for Prince-elector ("Kurfürst") Friedrich Wilhelm, 17th-century Duke of Prussia and Margrave of Brandenburg.  She was the fourth pre-dreadnought of the "Brandenburg" class , along with her sister ships "Brandenburg" , "Weissenburg" , and "Wörth" .  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.  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.

Virginia-class battleship: The "Virginia" class of pre-dreadnought battleships were built for the United States Navy in the early 1900s.  The class comprised five ships: "Virginia" , "Nebraska" , "Georgia" , "New Jersey" , and "Rhode Island" .  The ships carried a mixed-caliber offensive battery of four 12 in and eight 8 in guns; these were mounted in an uncommon arrangement, with four of the 8-inch guns placed atop the 12-inch turrets.  The arrangement proved to be a failure, as the 8-inch guns could not be fired independently of the 12-inch guns without interfering with them.  Additionally, by the time the "Virginia"s entered service, the first "all-big-gun" battleships—including the British HMS "Dreadnought" —were nearing completion, which would render mixed battery ships like the "Virginia" class obsolescent.

Pre-dreadnought battleship: Pre-dreadnought battleships were sea-going battleships built between the mid- to late 1880s and 1905, before the launch of HMS "Dreadnought" .  Pre-dreadnoughts replaced the ironclad battleships of the 1870s and 1880s.  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.  They were powered by coal-fuelled triple-expansion steam engines.

24 cm SK L/40: The 24 cm Schnelladekanone Länge 40, abbreviated as 24 cm SK L/40, was a German naval gun developed in the years before World War I that armed a number of the Imperial German Navy's pre-dreadnought battleships and armored cruisers. Later guns removed from these ships were converted to coastal artillery and were used during World War I and World War II.  The actual bore diameter was 23.8 cm , but the classification system for artillery rounded up to the next highest centimeter.

SMS Brandenburg: SMS "Brandenburg" was the lead ship of the "Brandenburg"-class pre-dreadnought battleships, which included "Kurfürst Friedrich Wilhelm" , "Weissenburg" , and "Wörth" , built for the German "Kaiserliche Marine" (Imperial Navy) in the early 1890s.  She was the first pre-dreadnought built for the German Navy; earlier, the navy had only built coastal defense ships and armored frigates.  The ship was laid down at the AG Vulcan dockyard in 1890, launched on 21 September 1891, and commissioned into the German Navy on 19 November 1893.  "Brandenburg" and her three sisters were unique for their time in that they carried six heavy guns instead of the four that were standard in other navies.  She was named after the Province of Brandenburg.

Wittelsbach-class battleship: The "Wittelsbach"-class battleships were a group of five pre-dreadnought battleships of the Imperial German Navy.  They were the first battleships produced under the Navy Law of 1898.  The class was composed of the lead ship, "Wettin" , "Zähringen" , "Schwaben" , and "Mecklenburg" .  All five ships were laid down between 1899 and 1900, and finished by 1904.  The ships of the "Wittelsbach" class were similar in appearance to their predecessors of the "Kaiser Friedrich III" class , however, they had a flush main deck, as opposed to the lower quarterdeck of the "Kaiser Friedrich" class, and had a more extensive armor belt.  Their armament was almost identical, though more efficiently arranged.

Deutschland-class battleship: The "Deutschland" class was a group of five pre-dreadnought battleships built for the German Kaiserliche Marine.  The class comprised "Deutschland" , "Hannover" , "Pommern" , "Schlesien" , and "Schleswig-Holstein" .  Built between 1903 and 1908, the ships closely resembled those of the preceding "Braunschweig" class , though they had stronger armor protection.  They were made obsolete before they were even completed by the launch of the revolutionary Royal Navy battleship HMS "Dreadnought" in 1906.  As a result, they were the last ships of that type built for the German Navy.  They were followed by the "Nassau"-class battleship s, Germany's first dreadnought battleships.

List of coastal defense ships of Germany: In the 1880s, Germany built a series of coastal defense ships to protect its coastline on the North and Baltic Seas.  During the 1870s and early 1880s, the Imperial German Navy had built a number of ironclad warships of various designs.  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.  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.  These vessels were intended only for defense of German harbors.  Six of them were built between 1888 and 1894.  Another two ships of the "Odin" class were built to a modified design between 1892 and 1896.
