history

The H8K "Emily" (Allied codename) heavy seaplane was a part-time transport aircraft used by the IJN for heavy seaplanes (transport type known as "Clear Sky")
In the early stages of World War II, with the successive service of large Allied seaplanes, the IJN realized the need for an ocean going seaplane to undertake long-distance bombing missions. Therefore, based on the research and development experience of the H6K heavy seaplane, the H8K heavy seaplane was developed.On December 29, 1940, the prototype was assembled at the Osaka factory in western Sichuan, and the first test was conducted with a crew led by Hiromitsu Ito; Although its control performance is relatively good, its surface handling and power performance are not satisfactory, and it has also encountered two major problems: 1. Water splashes during takeoff and landing will hit the propeller, and even splash into the air intake, causing engine failure; 2. It is very easy for airplanes to experience the phenomenon of "dolphin jumping" during landing. For the first issue, a wave blocking version was installed below the nose to solve it; For the second question, the pilot found that increasing the lift angle by 4-5 ° during landing could solve it, so no modifications were made to address this issue.
Finally, the improved H8K was officially delivered to IJN on March 25, 1941
H8K participated in a famous surprise attack during the early stages of the war:
The second bombing of Pearl Harbor
Due to the failure of the first surprise attack to achieve the expected results, IJN planned for H8K to take off from the Wojie Atoll controlled by the former Japanese Empire and fly to Pearl Harbor (about 3700 kilometers away), with Japanese ocean going submarines conducting intermediate refueling missions for H8K.
On the midnight of March 4, 1942, two H8Ks took off and successfully refueled on March 6 before reaching the airspace over Pearl Harbor in the early morning of March 7. Because the US military changed the radio password, the old Japanese Empire was unable to obtain the latest weather forecast. When the pilot flew over Pearl Harbor, he found that thick clouds obscured the target, and the bombdropped completely deviated from the target. IJN also planned a third surprise attack on Pearl Harbor, but because bombing was useless at this time, it ultimately came to nothing
The H8K has full production capacity and estimated performance. Generally speaking, it has a total of 11 machine guns, with comprehensive firepower coverage and thick armor. It can even survive being surrounded by several enemy planes. The H8K may even chase after enemy heavy bombers and seaplanes for combat.

The protection and firepower of H8K are very strong,So her journey is very long.up to 7600 kilometers, they often have to fly for several days. Pilots often feel tired and hungry, so the plane is equipped with food warehouses, makeshift beds, and even a small refrigerator
The airplane is from Leiji Matsumoto's manga«The Cockpit »is an episode that tells the story of a homeless man who, after joining the military, makes the H8K heavy seaplane his home and leads his crew to battle several enemies over the Pacific Ocean.

AG1: Autonomous driving
