Japan was forced to send a part of its navy to the south, and continued to secretly concentrate its main force in the Busan Port area. The Japanese fleet has not entered the port. It stayed in the eastern waters of Busan Port during the day and then secretly advanced to Jeju Island at night.

Japan already knew that China's S-10ZC series patrol aircraft had night reconnaissance capabilities, and the Japanese army did not have night fighters to defend against such patrol aircraft at that time, so they could only adopt a quick victory strategy, that is, the main landing troops set off at night, and

The main fleet set off at 3 a.m. and arrived at the combat waters at 7 a.m. to cooperate with the landing troops to carry out major battles.

This is the only extreme strategy for Japan to fight against China's night reconnaissance capabilities. It is feasible on the surface, but there is a special risk, that is, it is easy to be separated from the main fleet and the landing force.

In the absence of aircraft carriers, once the main fleet is attacked by Chinese naval aviation forces in advance, the Japanese air force deployed in southern North Korea will face a dilemma, either giving up the landing force or giving up the main fleet.

As the air combat on the Kaesong defense line was still ongoing, Japan had not had many air force forces that could be transferred to the naval battle of Jeju, with only more than 700 fighter jets, which could barely compete with the garrison air force on Jeju Island.

Therefore, the Japanese army's policies are still very risky.

But for the Japanese army, they lacked more suitable choices in addition to taking risks.

Since mid-November 1939, the Japanese army aviation units at the Ruisan-gun Airport in North Korea have been sending planes to reconnaissance the waters between Weihai Port and Tangjin Bay in North Korea. This 160-nautical miles wide water area is China Central Airlines United

The only way for the fleet to move south.

Because the bases of the Central Joint Fleet are scattered in Jinzhou-Lushun, Weihai-Qingdao, the Second Joint Fleet is deployed in Qingdao Port, which is outside the scope of the Japanese reconnaissance, but the Japanese army has been convinced that the Second Joint Fleet is in Taiwan

The South Pacific waters between Brunei, so I was not very worried that this aircraft carrier group would threaten the landing operations on Jeju Island.

The first fleet of the Central Joint Fleet has been supporting the Northeast Defense Forces in northern Korea. The reconnaissance aircraft of both sides have been constantly meeting in the Weihai-Tangjin waters, and there have been many conflicts. The Japanese reconnaissance aircraft are not J-5 electronic reconnaissance aircraft at all.

The opponent of the J-303 Sea Snake fighter made the Japanese reconnaissance plane shot down many times, but made the Japanese base camp feel a little more at ease.

In order to capture Jeju Island, the Japanese base camp established four ports in Wandao County, which is only 55 nautical miles away from Jeju County. After transporting the first batch of combatants to the south, the landing ships returned here to transport the second batch, the third batch, the first batch, the first batch. The landing force approved was a division, and two divisions and an armored brigade were dispatched to conquer Jeju Island with 75,000-80,000 troops.

In the planning of the Japanese base camp, the most important thing is the tactics of the main naval fleet of 10,000 artillery forces. At that time, the main Japanese naval ships will basically gather here to carry out comprehensive artillery bombardment on Jeju Island, destroy the fortresses on the island, and cover the island. Force attack.

To this end, the Japanese base camp conducted an exercise on Sado Island. While landing and fighting, it dispatched several aircraft to patrol over the air to observe the location of the opponent's fortress. The Japanese main battleship group then carried out rotational shelling of the fortress according to the coordinates.

Such a plan is good, but the prerequisites require the Japanese to eliminate the two air divisions deployed by the Chinese Air Force on Jeju Island, and also assist in the defense of the J-5 tiger shark fighter bomber flying from Jiangsu and northern North Korea to support. When the fighter was upgraded to the J-5D model, it was equipped with two SELM-2800-14 of Shenyang Liming Company, or the Pratt & Whitney R-2800-8 engines, with a single power of 2,240 horsepower and a cruising capacity of 520 km/h. The fastest speed and limit is 630 km/h, the practical maximum ceiling can reach 11,000 meters, and the regular range is 2,200 kilometers.

This heavy fighter bomber, which is almost equivalent to the size of a medium-sized bomber, was officially installed in the DD Corporation's transistor Doppler radar "Rainbow ERD-10" during the J-5D model in 1938, although it was the first generation Doppler Radar, but its performance is still beyond the conventional tube radar.

Due to the lack of suitable high-altitude fighter jets in the Japanese army, the J-5D Tiger Shark fighter bomber can attack normally even during the day, without fear of the Japanese 97 Land War. After encountering the 97 Land War, it also adopted a dive-style strafing attack, immediately after the attack Flying back to the sky, the 1997 land battle entangled.

This attack method makes the 97 Land War completely without any response.

With the J-5D Tiger Shark fighter bomber's ultra-long range, even if it takes off from Nantong, Jiangsu, Yancheng and Xinchuan Air Force Base in northern North Korea, it has the ability to carry out aid operations in Jeju. Moreover, the service scale of Tiger Shark fighter bomber in the Imperial Air Force The total number has exceeded 3,000 aircraft, and its multi-purpose and universal performance allows it to bomb Japan's mainland in clusters, without the need for the companionship of fighters, or provide protection and companionship for larger-scale heavy bombers.

Of course, this is to bully the Japanese army lacking suitable high-altitude fighter jets. If it were facing countries like Britain, Germany, the United States, the Soviet Union and France, as long as the opponent had suitable high-altitude fighter jets, the empire would not produce so many tiger shark fighters on a large scale.

In short, the value of this thing is to bully Japan's short and poor.

In order to deal with the tiger shark fighter jet, the Japanese army also came up with a lot of crazy ideas, such as installing anti-aircraft machine guns on a 97 land war. Perhaps only countries like Japan, which are driven crazy, will come up with such a thing, just like theirs. Torpedo torpedo.

The Japanese army also practiced a lot of tactics to try to curb this high-altitude advantage. Especially during the landing operation of Jeju Island, they installed a large number of legal 75mm anti-aircraft guns on the ships, trying to defeat China's tiger sharks and let these tiger sharks have No return.

In early December 1939, as the weather gradually became colder, after thinking that it was foolproof, the Japanese base camp issued a final combat plan in the name of the emperor's imperial edict, and the Imperial Navy's Second Air Combined Fleet circled around the Taiwan Strait. Then he secretly returned to the sea area between Shanghai and Nagasaki, where he was secretly on standby.
