Yan Renhao only took one day to revise the battle plan, and then handed it over to the two civilian staff officers arranged by Gan Yongxing. This battle plan will first be reviewed by Gan Yongxing, then sent to the capital to be handed over to Nie Renfeng, and finally handed over by the naval commander to Xue Xiyue, the prime minister of the empire. Under normal circumstances, the Prime Minister does not read all the battle reports, which is a special case, after all, the attack on the Panama Canal is very critical.

After writing the battle report, Tan Renhao followed Gan Yongxing's instructions and seized the time to familiarize himself with the current situation, and what he was most concerned about was the changes in the Imperial Navy's fleet.

This is the fourth major refitting of the Imperial Navy during the war, and not only will the naval aviation be equipped with the latest types of tactical bombers, but the strategic strike forces will also receive new models of heavy bombers. In addition, the last two "Lake" class aircraft carriers were also delivered to the Navy two months ago, because there was no rush to integrate these two aircraft carriers into the fleet, and the Navy spent a lot of time testing the performance of the aircraft carriers. One of the aircraft carriers was temporarily assigned to the reserve force for training to replace the disrepaired "Xuanzong", and the other was temporarily used to test various new ground equipment. Especially those electronic devices that have only been developed. As long as necessary, these two aircraft carriers can be incorporated into the fleet at any time and go to the front line of the battlefield.

The new bomber, developed by Hafei, was named the "Falcon", which is a bird of prey that specializes in hunting other birds. The development of the Falcon is much slower than that of the Peregrine Falcon, and its core, that is, the power system, is the same as that of the Peregrine Falcon. It is only in order to prolong the service life of the engine that its ultimate output power is limited, unlike the "Peregrine Falcon", which can make the engine work at its limit for a short time when it is in the air battlefield.

The Falcon was the Imperial Navy's first general-purpose tactical bomber, and its design was very different from previous bombers. In addition to the fact that the block is relatively large. The biggest external feature of this bomber is the use of embedded bomb bays. Previously, naval tactical bombers were only used with external pylons and torpedoes. Bombs these were hung on the bomber fuselage. Or the pylon under the wings

On and for the first time the "Falcon" set up an internal bomb bay.

The U.S. Navy first adopted the internal bomb bay ground design method, and the internal bomb bay has advantages and disadvantages. The benefits are. It reduces the ground resistance of the bomber during flight, makes the ground surface of the bomber smoother and smoother, and improves the flight speed and flexibility under the same conditions. In addition, the built-in bomb bay improves the safety of the ammunition, which has been tested by Hafei itself. The bomber can land on the aircraft carrier with a third of the fuel ground remaining. Instead of having to drop the ground ammunition before landing, as in the past, it is still a question whether the Navy will change the combat regulations because of this, after all, landing with ammunition is still more dangerous. The disadvantage is that the size of the bomb bay is fixed. There is limited room for improvement, and it may not be possible to use new, more powerful munitions in the future. Also, if the bomb bay door comes out of the applause. Then it is impossible to throw the ammunition out. In addition, the built-in bomb bay occupies the limited internal space of the aircraft, in order to meet the tactical performance of other places, in addition to increasing the size of the aircraft, other equipment must be compressed, and the internal space of the aircraft must be saved as much as possible, which is a huge problem in the design.

It is precisely because of these three shortcomings that the Navy has previously demanded external ammunition and tried to avoid the use of internal bomb bays. Back in 24 hours. Shen Fei developed a built-in bomber on the basis of "shooting water birds". Although its speed has been increased to ■40 knots compared to the "Shooting Bird", its agility has also increased. However, the Navy did not purchase it in the end, and the reason is precisely because of the aforementioned ground, the built-in bomb bay is small, and it is difficult to use the improved ground ammunition. The reliability of the hatch is not high and it is easy to fail. Most seriously, the built-in bomb bay occupies the interior space of the aircraft, and its combat radius is about 70 nautical miles shorter than that of the "Shooting Waterbird". This is the most intolerable for the Navy .

Hafei also encountered these problems when designing the site, which is also the main reason for the slow development progress of the "Falcon" land. In addition to the three main issues, there are a lot of small issues that need to be addressed. It is indeed incredible, and the genius designers of the Ha enclave have come up with a solution to the three main problems, and the design of the "Falcon" is the "Peregrine Falcon" team, and the super creativity is the main factor in the team's success.

The solution to the built-in bomb bay is very creative. The designer set up a combined pylons in the bomb bay, and the maximum standard can hang two 500-pound bombshells at the same time. Can be in general. Dive bombers are not going to hang two bombs on the ground. And this will greatly affect the combat radius of the aircraft. Therefore, the designer set up a built-in auxiliary fuel tank interface in the bomb bay, so generally only one 500-pound bomb is hung, and then a built-in auxiliary fuel tank that can hold about 450 gasoline is hung. This solves the contradiction between the capacity of the bomb bay and the ground fuel carried by the aircraft. Of course, when used as a torpedo bomber, because the torpedo is much longer and heavier than the bomb, it is impossible to carry the built-in fuel tank. It was only possible to increase the range by carrying two drop fuel tanks under the wing. finish

The solution to the reliability of the bomb bay door is more ingenious. In the past, Shen Fei was engaged in a hydromechanical rotating mechanism, which was very complicated, as long as there was a problem with one part. The bomb bay door won't open. The engineer of the Ha enclave directly reversed the thinking that the bomb bay door does not rely on the hydraulic cylinder to push the ground open. Instead, it pulls, and in addition, opens with the help of the bomb bay door itself with the help of its own weight. After thousands of wind tunnel tests, it has been proved that the reliability of this mechanism is after three decimal places, that is, the applause rate is less than 1 in 10,000, which is even lower than the probability of a bomb pylon failure!

There are many ways to solve the problem of the internal capacity of the aircraft, mainly the amount of fuel carried inside, such as carrying the built-in drop fuel tank in the bomb bay mentioned earlier, hanging the drop fuel tank under the wing, and so on. But in most cases, the bomber cannot hang the auxiliary fuel tank, after all, the bomber takes off and lands on the aircraft carrier There are restrictions on the weight of the take-off and landing. Therefore, the only way to do this is to increase the size of the aircraft. In order to increase the interior space of the aircraft, which in turn will increase the weight of the aircraft, reducing the speed and agility of the aircraft. This is a difficult contradiction to resolve. Finally, Harbin Enclave engineers made extensive use of light metals such as aluminum alloys on their aircraft. At the same time, a large number of wind tunnel tests were carried out in the aerodynamic design of the aircraft, and the best aerodynamic layout was finally designed.

It can be said that the "Peregrine Falcon" and the "Falcon" are twin brothers. The development of the two types of fighters began almost at the same time, but because the navy had a more urgent demand for fighters, Ha Fei first concentrated his efforts on overcoming the difficulties in the development of the "Peregrine Falcon", first completed the design of the "Peregrine Falcon", and quickly put it into production. As a result, the Falcon was equipped almost a year later than the Peregrine Falcon. That's a good thing and a bad thing." A large number of advanced designs and advanced equipment on the "Peregrine Falcon" have been tested in the battle and proved their practicability, so Hafei has adopted a large number of successful design experience and mature equipment on the "Peregrine Falcon" when designing the "Falcon" land. One of the simplest and most important components. Both fighters used the same engine. This is a basic requirement for the Navy. At the same time, it also proves that the performance of the "Wind 24" engine is sufficient to meet the requirements of the Navy.

In terms of overall performance." The Falcon was one of the finest carrier-based bombers of the entire Second World War and remained in service until after World War II. Until the 60s of the 20th century AD, naval aviation was still equipped with thousands of "Falcons", and many countries even used them until the end of the 80s of the 20th century AD. This is enough to prove the advanced nature of the "Falcon". At that time." The "Falcon" is the first carrier-based bomber capable of reaching a speed of 350 (equivalent to 650 miles per hour), which is a test speed without hanging bombs, and in a normal combat state. If the ground is a bomb. The maximum speed is about 330, and if the ground is torpedoed, its maximum speed is about 310, which is 100 knots higher than the "water birds" and "sea eagles" that the navy was equipped with before, and even faster than many fighters in the middle of the war.

Back in June, the Navy began testing the "Falcon", and according to the plan, the new bomber would be ready to equip the troops by the end of July, when . The First Fleet plans to receive the Falcon as the first batch, but after receiving the New Earth mission. The First Fleet did not immediately change its outfit. The real first place to be redressed as a Falcon was the Second Fleet's Fifth Task Force. That

At the beginning of August, eight squadrons of "Falcons" took off directly from Guangzhou, landed in the Lion City, Colombo, Moroni, and Durban along the way to refuel, and flew for a total of 50 hours to Cape Town, and on the third day of arriving in Cape Town, the first "Falcon" landed on the aircraft carrier of the Fifth Task Force. This can be said to be the first test of the "Falcon" land, and it is also a severe test. A freshly equipped bomber, flying thousands of nautical miles over a long distance, only refueling and not maintaining halfway, and in the end eight squadrons of the "Falcon" only 4 were left behind. All the others arrived in Cape Town and were overhauled that evening. The next day it flew up. This is enough to prove the reliability of the Falcon, which is one of the most important characteristics of the bomber.

At that time, the HNA ground combat units were divided into three groups, one group to fight on the front line, one group to train in the rear, and the other group to rest and recuperate. The first units to receive the Falcon were the units that carried out the training, and these units arrived at the front line in September and October. Succeed the ground troops who have been fighting on the front line for two months." The Falcon also took part in the bombing of Oahu for the first time at the end of September and performed well in the battle. In the nearly month-long battle, the first three squadrons deployed to Kauai carried out more than 2,100 ground bombing missions, dropped ground bombs, and only 11 were shot down, with a battle loss rate of less than 1 percent.

The Third Fleet was withdrawn from the front line in early September to rest and recuperate, and the refitting work began at the same time. Now, the fleet is operating near Guam, and the ground leave of the pilots of the carrier-based bombers has been canceled, and all are undergoing intense adaptation training. This is also the most troublesome part of the Navy's refitting training, and the "Falcon" is a general-purpose bomber, so the Navy had to revise the ground establishment of the carrier-based aviation at this time, cancel the "dive bomber" and "torpedo bomber" squadrons, and merge them into a unified bomber unit, and finally revised the entire air force ground establishment because of this.

In the end, the situation of the establishment of the Navy's carrier-based aviation was . Each aircraft carrier is equipped with a carrier-based aviation group, each of which has a fighter squadron, two bomber squadrons, a reconnaissance aircraft squadron, and an independent liaison transport aircraft squadron. Specifically, the readiness is as follows: 36 "Peregrine Falcon" fighters, 72 "Falcon" bombers, 12 "Falcon" ground reconnaissance models, 4 light transport aircraft (not permanently stationed on aircraft carriers), a total of 124 fighters, and the combat time and ground strength is 120.

Judging by the situation reflected by the Third Fleet, the bomber pilots had a love-hate relationship with the "Falcon". For most of the pilots, they don't like this universal bomber . Dive bomber pilots believe that the "Falcon" is not as good as the "Shooting Waterbird" in its diving performance, especially when it changes to a dive ground at low altitude, it is not as flexible as the "Shooting Waterbird". Excessive altitude speed is also a problem. Torpedo bomber pilots believed that the "Falcon" was inferior to the "Sea Eagle" in its ability to fly at low altitudes, especially after completing the bomb drop. When it comes to evasive ground, the Falcon looks a bit clumsy. The fundamental problem is that the advent of the "Falcon" makes the Navy no longer need two types of bombers, so each bomber pilot must have comprehensive capabilities, even if the Navy temporarily retains two squadrons, under normal circumstances, one squadron still performs dive bombing missions, and the other squadron performs torpedo bombing missions. But in the future, the boundaries between these two missions will definitely disappear. finish

The Falcon's speed, robustness, reliability, endurance, and huge bomb-carrying capacity were unanimously affirmed by the pilots, and this also changed the embarrassing situation that the bomber's bomb load and speed were not as good as the Peregrine Falcon, thus allowing the bomber pilots to regain their self-confidence. This is where the Falcon is popular.

The first fleet's refitting work has been arranged, and Gan Yongxing handed over this task to Hao Dongjue, without letting Tan Renhao worry about it. Now the First Fleet's warships are being repaired in Naha and other Imperial ports, and the air force is concentrated on Ryukyu Island for refitting training, and by the time Tan Renhao goes on his next expedition, the First Fleet will have a stronger and more rapid bomber force.
