Menlou Military Port Area and Yantian Port Area.

The so-called Sanao is East Australia, Western Australia and North Australia, which are three semi-enclosed port areas respectively. North Australia is located on the north side of the middle and consists of Baima Port and Yantian Port. It exists on the periphery of these three semi-enclosed port areas.

A natural circular island ridge makes San'ao's real exit to the East China Sea only 5 kilometers wide, while the total area inside is 770 square kilometers. There are a large number of island ridges in this Dagang District of Sanduo's, although the area is large.

, but the overall flight environment is not high, especially when flying at low altitudes.

This is exactly where Sanduao is better than Luoyuan Bay as a military port center.

The headquarters of the Chinese and Japanese naval forces are too close to each other. For this reason, the Sanduao Naval Base has continuously added a large number of air defense facilities during the construction period. In the simulated test of the military headquarters, its air defense strength is sufficient to withstand more than one thousand aircraft.

Fighter plane.

On the east side of Sanduao, the Empire has a radar base in Taishan Islands, Dongyin Island, Pengjiayu, Island Island, Keelung, Taiwan, air force bases in Taipei and Fuzhou, and a backup base in Shouning, Fujian.

air force base.

It is precisely because of this layer of defense that Japan has a very low possibility of breaking through, and the empire seems particularly relaxed and absolutely does not believe that Japan dares to attack Sanduao Naval Base.

Song Biao guessed that Japan might indeed take the action of sneak attacking the Sandu Ao Naval Base, so as to suddenly declare war, and attempt to destroy the main force of the Chinese navy before the war began. It is normal for the Empire to think this way, but Song Biao does think Japan really

Not having this kind of strength.

Judging from the existing information, the development plan of Japan's Type 00 ship aircraft was very smooth. This new aircraft, which was later called the Zero fighter, has very low wing loads, plus a fully hard aluminum alloy fuselage and medium

The overall design parameters of Shimaei engine are indeed very excellent, but for now, Japan's real main combat aircraft are the 96-ship battle and 97-ship attack that were just put into service in 1936. Its carrier-based dive bomber is still in the biplane stage.

The 94th ship explosion, the overall combat parameters of these three are still a certain gap compared with the current J3\4\303 and G2 of the Chinese Navy.

The most important issue is the range. The combat radius of the 94th ship explosion and its improved model of the 96th ship explosion is only 450 kilometers. This means that the Japanese aircraft carrier group must arrive at the area of ​​125 East longitude and 26 North latitude before they can initiate the Sandu.

The attack from the Australian Naval Base, and in this combat area, the Imperial Air Force's 215th Air Force Division in Taiwan and the 223rd Air Force Division in Wenzhou both happen to have the best attack range.

With the 210th Air Force Division stationed in Fuzhou, the Japanese Navy almost fought back against three air divisions and the Imperial Navy's Southern Fleet Air Force First Aviation Brigade, its fleet of air defense forces could not hold on.

If the Japanese army wanted to carry out aircraft carrier air strikes outside the combat range of the three air divisions of the Empire, its carrier-based aircraft range was simply not enough to support this operation. If it chose to engage in air combat with the air division first, it would be difficult to use its aircraft carrier group's strength

Support such a large-scale combat plan.

This means that the Japanese Navy can only take a risk and deploy an army air force in Okinawa Prefecture to support operations. Even so, the Japanese Navy still has to take great risks because its carrier-based aircraft has insufficient range and can only be very

Local area close to China's naval base.

Regardless of whether the sneak attack was successful or failed, its mothership group had to flee to Okinawa at high speed. The distance was about 150 nautical miles, which was basically a 5-hour flight, of which at least 3 hours were in China.

Within the range of the Air Force's counterattack, and its own is basically equal to zero defense, the only rescue can be the Japanese fighter jet group from the Okinawa base.

This is indeed too risky.

The carrier-based aircraft currently in service in the Empire were basically the second generation of the J\G series that was put into service around 1933, namely various improved models of the J3\4\303 and G2 series. The Army's heavy fighter jets have a twin-engine J5.

The overall design and architecture of this fighter is basically the same as the later P-38 of the US military. With its huge body, its combat radius is close to 1,300 kilometers. It can be said to be a special fighter specially developed for Japan and is also the world's first.

Carrying a truly heavy fighter jet.

Because this J-5 Tiger Shark fighter is equipped with the first-generation fighter's airborne radar and turbocharger technology, it can even replace the S-series patrol aircraft at high altitude cruise reconnaissance, and can also carry 2 905KG bombs, or

4 230KG bombs.

The J-5 Tiger Shark fighter is mainly deployed in coastal air bases, Fuzhou, Taipei, and Jiaxing air bases, but the number is not large, because it does not have much advantage in close combat, and its biggest advantage lies in range.

Night battle, the caliber and range of airborne cannons, as well as excellent parameters for high-altitude navigation.

Overall, the J-5 Tiger Shark fighter is positioned more like a fighter bomber in China, and is a medium-sized fighter bomber with high combat performance parameters. When dealing with the Japanese opponent, the J-5 Tiger Shark fighter has a high altitude and high range advantage.

It is extremely obvious and an absolute advantage.

The current gap between Japan and the empire in the aviation field is the level of the overall two-generation aircraft. Even if the empire has greatly reduced its research investment in the field of propeller fighter after 1935, Japan will not be able to catch up within five years, because both sides

The problem of gap in basic industrial level.

The Empire's propeller aircraft engines are mainly supplied by three companies, belonging to different series and designs, with a total horsepower of more than 1,000 horses, while Japan's latest Nakajima Ei engine has a maximum power of only 950 horses, and Japan also lacks the use of turbochargers.

Experience in pressing technology and industrial materials can only be added with first-level machinery, and the newly developed 14-cylinder engine is still a single-row.

The Imperial's current propeller fighter mainly uses three types of aviation engines, namely Northeast Heavy Industry's star-shaped air-cooled engine, Jiangnan Fudao Company's Fuke series single-row 4-axis U-series engine and D-series Alison liquid-cooled engine.

Fuzhou Heavy Industry's Southeast Star V series engine.

The characteristics of these three engines are different, and are generally star-shaped as the main body. The Fuke U-series engines are mainly used in large passenger aircraft, patrol aircraft, transport aircraft and heavy bombers. Their characteristics are that the body structure is larger and heavier, but fuel oil

The D-series engine itself is between the star and the Wright cyclone engine, and adopts a liquid-cooled design, unlike the traditional star engine that will cause the propeller and the head part to be as big as that of the pilot, and will not block the pilot's field of vision.

.

The D-series engine is similar to the Merlin engine of the Spitfire fighter. Its engine has a long overall structure and a diameter much lower than that of the air-cooled engine. It is mainly used in the J-3 Viper and J-303 Sea Snake fighter as a carrier-based aircraft.

The series of fighter jets have good aerodynamic structure, high instantaneous hovering and climbing rate, good fighting performance, and insufficient high-altitude combat performance after being compensated by turbocharger technology, and overall it can be maintained at a high level.

There are two designs for Fuzhou Heavy Industry's Southeast Star V series engine, one is a regular V, and the other is an inverted V design similar to the German DB601. The former is currently used less, and the latter has similar advantages to the D series.

, but there is a large space to increase the secondary or turbocharger device to make up for the aircraft's combat performance at high altitudes.

At present, the Empire has greatly reduced the investment in the development of new propeller fighters. Currently, it is mainly based on the active fighter jets to make minor modifications and upgrades. The main fighter jets are J-4. J-4 Blitzkrieg adopts the dual-row 18-cylinder of Northeast Heavy Industry.

The star-shaped air-cooled engine has a horsepower of 1350KW, about 1805 horsepower, and its test model has even reached 2400 horsepower.

In fact, the Northeast Star series engine is the same as the Pratt & Whitney R2800, a subsidiary of United Industries, which is the same engine, except that the latter is only produced and sold in the United States and is specifically used in the U.S. Air Force and Naval Air Force.

Northeast Heavy Industry is also developing a larger-sized star engine with a double-row 22\24 cylinder, but the diameter of this engine has reached an unacceptable level and can only be used in air transport aircraft, passenger aircraft and patrol aircraft, and in the field of high-power

, the performance of the star-shaped air-cooled engine may not be better than the U-series engine of Jiangnan Fudao Company.

Because of the extremely powerful horsepower, the J-4 Blitz fighter has extremely high combat performance, but its only criticism is that the excessive engine front cover has a great obstacle to vision, which is very similar to the P47 and the Soviet pull series.

In this way, the J-4 Blitzf is still the main force among the Imperial active fighter jets, and its carrier-based aircraft model J-402 will be put into service at the end of the year.

Japan has a big gap in engines compared to China and the United States. It has indeed introduced star engines from the United States and has achieved a 14-cylinder design, but the gap in the material field is very obvious, so it cannot reach such a high level in China and the United States.

The level of horsepower.

The Soviet Union also faced this problem, and Japan and the Soviet Union had different ideas for solving the problem. The Soviet Union adopted a combination of multiple aircraft to make up for the insufficient performance of a single fighter, while Japan adopted a desperate approach to reduce weight. China and the United States were another line.

—Fight hard to increase the engine's horsepower.

The difference between these three ideas is mainly because of the different industrial strength and foundations of each country. China and the United States have a deeper technical accumulation in the fields of aviation engines and heavy industry, and there are conditions to continue to increase engines. However, Japan and the Soviet Union cannot do it, so they have to go astray.

Every.

So can we use a high-powered engine like China and the United States on an extremely light aircraft?

This is not possible, because the strength of the aircraft cannot meet the standards matched by the engine, unless it is abandoned and titanium alloy is directly used. The Empire has indeed invested a decade-long development cycle in the field of titanium alloys, in the ** style

The P series aircraft also uses some titanium alloy parts, but in terms of the overall fuselage, it is still impossible.

Titanium alloys are too expensive, difficult to process, high cost and low mass productivity, which is the biggest limitation at this stage.

Therefore, Chinese aircraft can only be more solid and have stronger horsepower, while Japan can only continuously reduce the weight of the fuselage and increase the sensitivity of the aircraft under the constraints of horsepower.

Both sides have different paths and the differences in aircraft combat parameters are not particularly large. In the end, which one is better or worse, then we can only answer it through war. (To be continued. If you like this work, you are welcome to come and go.
