Japanese battleship Fuji
Japanese battleship Fuji

The Fuji class was a two-ship class of pre-dreadnought battleships built for the Imperial Japanese Navy (IJN) in the mid-1890s. They were the first battleships in the IJN, and were constructed in the United Kingdom as Japan lacked the industrial facilities needed to build them. The ships participated in the Russo-Japanese War of 1904–1905, including the Battle of Port Arthur in February 1904 and two bombardments of Port Arthur the following month. Yashima struck a mine off Port Arthur in May and capsized while under tow several hours later. Fuji (pictured) fought in the Battle of the Yellow Sea and the Battle of Tsushima, and was lightly damaged in the latter action. She was reclassified as a coast defence ship in 1910 and served as a training ship for the rest of her active career. Fuji was hulked in 1922, converted into a barracks ship fitted with classrooms, and was finally broken up for scrap in 1948. (This article is part of a featured topic: Battleships of Japan.)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
