-Kaga was laid down at the Kawasaki Shipyard in Kobe as a 40,000-ton class large-scale battleship equipped with a 40 cm gun following the Nagato-class battleship in 1920.
-The next day, in 1921, it was launched and construction was proceeding smoothly, but when the treaty on disarmament, the Washington Treaty, was signed in the same year, the battleship holdings against the United States and Britain 5:3 were decided, The construction of battleships Kaga, Tosa and cruiser battleship Akagi, Amagi will be suspended.
-On the other hand, the CITES stipulated the amount of aircraft carriers to hold, but there was ample room in Japan, which had only one Fengxiang ship.
-Therefore, it was decided to reconstruct Akagi and Amagi, whose construction has been suspended, into an aircraft carrier, and construction will resume.
-However, in the Great Kanto Earthquake of 1923, the Amagi on the stern was destroyed and was abandoned, and it was decided to renovate Kaga into an aircraft carrier.
-Kaga was originally designed as a battleship, so it is slow and has a shorter overall length than Amagi during cruising, and struggles with the length of the flight deck.
-The aircraft carrier renovation work in Kaga began in 1923 (Taisho 12), but it was as difficult as Akagi for Japan, who had no experience building large aircraft carriers.
-The particular problem was the placement of the chimney.
-It seems that the arrangement that led to the stern to avoid disturbing the air flow of the flight deck failed, and the hot air heats the underlay officer's room near the smoke path, and it has become unusable for living.
-In addition, the weight was too heavy to ignore.
-The flight deck was also a three-tiered deck similar to Akagi, but this also has considerable operational restrictions, and since the performance of the aircraft is also significantly improved, early renovation was desired.
-However, due to the outbreak of the Shanghai Incident and the problem of budget execution, the second renovation work will finally be started in 1933 (Showa 8).
-The main points of the refurbishment are strengthening the engine department for speed increase and extending the total length (making it a smart ship type), further renovating to a flat flight deck all over, replacing chimneys, and island type bridge It was a new establishment.
-In this way, Kaga who renewed as a modern aircraft carrier was incorporated into the 2nd Squadron 2nd Squadron in 1935, and in the Sino-Japanese War of 1937, the Nanjing air raid in August and December We are expanding the support activities of land troops such as attacks in various parts of the South Branch and bombing of Guangdong in the following year.
-In December 1938, a small renovation work was carried out again, and the Japan-US war began in this state.
-In April 1941 (Showa 16), it will be incorporated into the new 1st Air Fleet 1st Air Squadron and will be paired with Akagi.
-Around this time, we will begin ferocious training in the Kyushu region assuming an attack on Pearl Harbor.
-And, in November when Japan and the United States suddenly announced, the Nagumo Mobile Task Force (the first air fleet backbone) secretly gathered on the single crown bay of Etorofu Island, followed the north route of stormy weather, which is anchored on 26th Sneak up to Hawaii's northern waters. -And on December 8th (7th day of the field), an air raid on Pearl Harbor, Hawaii, was devastating to the US Navy.
-From Kaga, 26 ships attacked by Maj. Gen. Hashiguchi and 9 battles of Captain Shiga participated in the first attack, and 26 ships of Captain Makino and 9 battles of Captain Nikaido participated in the second attack. doing.
-In this way, the Nagumo Fleet, which showed great success at the beginning of the war, made a triumphant return at the end of the year, and departed to Track Island early in the new year, and later attacked Rabaul, Cavien, Port Darwin, etc. with Akagi and Soryu, Hiryu in the second battle. Is giving.
-After this, only Kaga left the main unit and returned to Sasebo to repair the groundwater.
-For this reason, I am not participating in the Naokan Fleet operation in the Indian Ocean.
-In May 1942 (Showa 17), when the Midway strategy was announced, I returned to one ship and aimed at the Midway.
-On the fateful June 5, we will launch 18 ship explosions led by Captain Ogawa and 9 units of Captain Iida's Zero Fighter in the attack on Midway Island in the dawn.
-After that, it is the same as Akagi, but it is not clear what Kaga and the executives below the captain were doing during this time.
-It can be inferred that he was probably going back and forth due to repeated command changes, but he does not seem to have commented on Maj. Gen. Yamaguchi of the 2nd battle.
-Was the decision entrusted to the headquarters?
-At 7:23 am, four 500 Kg bombs released by SBD-3 Dauntless finally caught Kaga, and the captain Colonel Okada died in the first hit.
-And the bombs that were rumbling were triggered one after another, causing a big fire, and desperate fire extinguishing work became empty and untouchable.
-Kaga, who ignited the gas station at 4:25 pm after the total crew had left the ship, had a huge explosion and disappeared into the sea north of Midway.
-Akagi, Kaga, Soryu, Hiryu. The world's strongest aircraft carrier unit was destroyed with caution and sluggishness along with excellent crew members, and the Japanese Navy will be defeated while dragging the aftereffects.
