Interpretation of crossbow level

Judging from what they represent, these two words should have a strong military meaning. Yes, the names crossbow class and super crossbow class really originated from the navy. The early 20th century was the rising stage of gunboat doctrine. 1905, the British navy began to build intrepid class battleships. The first ship, HMS. The dreadnought has adopted a completely different design from the previous large ships. It concentrated heavy artillery, canceled the traditional second artillery used for attack and destruction, and used a high-power steam engine. It can be said that the defense is very strong and it can reach a high speed of more than 20 knots. Since then, due to the needs of naval competition, countries have begun to build battleships with the same specifications as the fearless class. In order to divide and summarize this kind of battleships, they are collectively called dreadnoughts.

But what is the relationship between the fearless battleship and the crossbow battleship?

There is such a passage in the article "The Vast Ocean is a Casino", which was written by Teacher Tianren Yu later.

1907, just after the Russo-Japanese War, Britain built the "crossbow-class" battleship Dreadnaught. The standard displacement of the battleship dreadnought is18,420 tons. It adopts a longbow ship type, which eliminates the underwater impact angle of the bow. It adopts a "full cannon" with five twin turrets 10 unified 12. A unified fire fighting system can be adopted. "Fearless" used four steam turbine propulsion devices on a large warship for the first time, and the maximum speed was increased to 265,438+0 knots, so it can sail at high speed for a long time and maintain good reliability. Compared with the old reciprocating steam unit, it has higher power and higher reliability. The intrepid's defense adopts surface hardening treatment, and the armor thickness of important parts reaches 1 1 inch, providing comprehensive protection capability. The watertight compartment in the waterline of the hull compartment cancels the transverse contact door, which strengthens the watertight structure and improves the anti-sinking ability of the ship.

The appearance of crossbow-class battleships immediately made the battleships "Xiangqu" and "Kashima" ordered by Japan from Britain in the Russo-Japanese War and the battleship "Tsukuba" built by China itself obsolete.

Only two years after the launch of the "crossbow-class" battleship in Britain, that is, from February 1909 to April 19 10, Britain built four more standard displacement ships, including Orion, Monarch, Conqueror and Thunder.

After reading this passage, you may wonder why it is also called "crossbow class" when it is clearly a intrepid class battleship. Among them, because Dreadnought spelled ドレドノト with katakana, and this title is really inconvenient for Japanese with poor English, we simply take the initial ド in Hiragana, that is, ど as the corresponding Chinese character.
