In fact, the efficiency of the turboprop engine is higher than that of the turbofan engine, not to mention the turbojet engine that is widely used now, which is why the turboprop engine sent by the China Consortium has so much horsepower, but unfortunately due to the larger diameter of the propeller, the speed is much lower than that of the turbo, only about 1,000 revolutions per minute.

In order for both the turbine and the propeller to work within the normal range, a reducer needs to be installed between them, and the reducer can be used to drive the propeller only after the reducer reduces the turbine speed to about one-tenth. This kind of reducer is very heavy, complex in structure, not only expensive to manufacture, but also weighs equal to the combined weight of the compressor and turbine, so it is difficult to equip this engine on a relatively lightweight fighter.

In addition, another disadvantage is that the turboprop engine is usually ducted higher than the turbofan engine, which causes the speed of the blade end part to be very high, which may produce shock waves, and the turboprop engine cannot exceed the speed of sound, which is completely unacceptable for fighters who are getting faster and faster.

The new Behemoth 3 transport aircraft was developed by the Northwest Aircraft Factory of the Chinese Empire, and with the help of this powerful engine, the performance of the new aircraft has made a qualitative leap. In order to increase the load capacity, the researchers installed four engines for the new aircraft in one go.

To increase the flight range is to increase the fuel capacity, and to increase the load capacity is to increase the fuselage, so the new aircraft can be called a real monster, its length has reached 58 meters, the height has reached 12.5 meters, the wingspan has reached 64.4 meters, the empty weight alone has reached 114 tons, and the maximum take-off weight is 250 tons.

Four high-powered turboprop engines allow the behemoth to reach a cruising speed of 680 kilometers per hour and a maximum speed of 740 kilometers per hour. In addition, the fuel tank capable of carrying 43 tons of fuel allowed the plane to fly up to 11,000 kilometers, and the maximum cargo reached a terrifying 80 tons, which can be described as a super giant in the Chinese Imperial Air Force.

The Behemoth 3 transport aircraft is the first special transport aircraft in the Chinese Empire that is not common to passenger aircraft, it not only carries a lot of cargo, but also can land on an airstrip, and is the absolute main force of air transport in the Chinese Empire today. At present, these transport planes are carrying 30,000 soldiers as the vanguard of reinforcements, heading to the battlefield in the port of San Diego, more than 5,000 kilometers away.

Marshal Pershing had a deep understanding of the combat effectiveness of the Chinese army for the first time, and in the record of his actual participation in the war, the first time he went abroad to fight, he encountered the Lanfang mercenaries led by Gao Hong, and that time he was beaten badly, and it was not until many years later that he knew that it was not the Imperial Army of St. Martin that faced him, but the world-famous Imperial Chinese Army.

But after all, that was a few decades ago, and the weapons and equipment of that time were not the same as they are now. But just when he thought that the Boston Empire's army weapons had caught up with or surpassed the Chinese Empire, the Chinese Empire made him understand what air superiority was.

Of course, at that time, the Boston Army participated in World War I as an ally of the Chinese Army, so he didn't have much intuitive understanding of the strength of the Chinese Army, and he didn't really confront it, at best, he only knew that it was very powerful. However, this landing operation made it clear to Marshal Pershing that there was still a big gap between the Boston army and the Chinese Imperial army, so he had to send more troops to besiege the port of San Diego, otherwise the troops in the Moss Kingdom would suffer.

In the fierce battle, the air forces of the two sides engaged in a fierce air battle, and the landed Golden Eagle 4B fighters cooperated with the Sailfish 2C attack planes of the Hainan Airlines, inflicting heavy casualties on the Boston Air Force. In particular, the long, medium and near air-to-air missiles of the Sailfish 2C attack aircraft have simply made the Boston Air Force want to die, and even the F86 Sabre fighter, which has just been reequipped with the whole army and made the Boston Air Force quite invincible, is also a complete defeat.

The fighters of both sides were deadlocked in the air, and on the ground, the Chinese Marines had enough heavy firepower, and they could even suppress the artillery fire of the Boston Army with the maneuverability of their self-propelled guns. The attack of the battleship's guns and the rocket artillery on the container ship also greatly supported the offensive of the ground forces near the coastline, and the battle between the two sides soon turned into a positional battle, and as more and more reinforcements were brought in from the sea, the Chinese Army even began to occupy a certain advantage.

Field Marshal Pershing never expected that the other side's reinforcements would come so quickly, and the Behemoth 3 transport plane could fly back and forth between San Diego Harbor and the Oahu Islands twice a day, which was enough for 30,000 troops each time, if not all of them, to fight against the Boston Army.

Marshal Pershing did not have any tricky feelings about this, on the contrary, he was still a little excited, after all, the Chinese Army came across the sea, they were more than 10,000 kilometers away from the domestic supply line, even if the Chinese Empire had the largest merchant fleet in the world, it could not support such a long supply line for a long time, so Marshal Pershing planned to use the port of San Diego as a bait to consume the national strength of the Chinese Empire and provide strong conditions for the operation on the Western Continent.

Indeed, without the help of Fang Xiaoyu and Xiao Feng's anti-heaven teleportation function, the landing operation of the Chinese army was greatly restricted, but Pershing did not know that such a fierce firepower and such a large deployment of troops were actually not the main offensive direction of the Chinese army, and at this time the North Road Group led by Zhang Haiyang was already preparing to start attacking.

As the military of the Chinese Empire, if you want to easily attack the New World, the best way is of course to land in the Saint-Martin Empire, but at the junction of the south and north of the New World is the Kingdom of Moss. The Kingdom of Moss is a country less than 500 kilometers wide, and the land area there is too narrow for the millions of troops of the current St. Martin Empire and the Boston Empire, and if the Chinese army joins in again, it will not be able to spread its strength at all, so this kind of operation will not have any effect, it is better to open up a new battlefield, which is more beneficial to the attack.

Because of this reason, Feng Ju first attacked the port of San Diego, and Zhang Haiyang's target was Portland Harbor, the northernmost point of the west coast of the Boston Empire, where the area is small, and there are not many flat beaches suitable for landing, so the garrison is only more than 20,000 people, and Pershing does not attach much importance to this, in his opinion, it is impossible to carry out a large army operation here, even if it is occupied, the Chinese army cannot transport a large number of troops and their weapons and equipment ashore in a short time.

If the time dragged too long, the Boston Army would have more time to mobilize forces and drive the troops that had already landed into the sea. Moreover, by landing in a place where it is inconvenient for troops to maneuver, the Chinese army will lose the most important suddenness of amphibious operations. However, Marshal Pershing ignored the fact that the weapons and equipment of the Chinese Empire were updated very quickly, and the performance of new equipment often subverted the previous laws of warfare.

The first to attack the North Attack Group were submarine submarine special forces, and these wetsuit-clad frogmen used torpedo tubes to enter the sea in the offshore area. After five kilometers of diving in the water, the frogmen landed on the weakly defended shoreline of Portland. The coastline here is so steep that it is impossible to land, so the Bostonians have no permanent presence here, and patrols pass only during the day.

The naval special forces did not act on their own, someone was already ready to cooperate with them. After Qiu Zhihong contacted the Intelligence Bureau, Fang Ruijun knew that Qiu Zhihong, who was released by his father, had actually become the leader of the largest Chinese organization in the Boston Empire, and he had never forgotten Fang Xiaoyu's kindness at the beginning.

According to Qiu Zhihong's original intention, after connecting with the Intelligence Bureau, he mobilized the entire Boston Empire's Zhi Gong Court personnel to carry out sabotage activities throughout the country to distract the Boston military, but after Fang Ruijun learned of this, he immediately stopped Qiu Zhihong.

The role of the inside line can only reflect his strength at a critical moment, and this is such a moment. After coming to the bottom of the cliff, Zhao Yiqun, the leader of the killer whale special forces detachment, looked at the luminous watch, and the time had come. He took out a waterproof flashlight, lit it, and shook it clockwise three times at the top of the cliff. Half a minute later, there was also a light on the top of the cliff, and after the same three turns, a few thick ropes were quickly lowered.

Taking advantage of the night, the sturdy special forces quickly climbed the cliff with weapons on their backs and big ropes in their hands. "Hello, I am the president of the Portland Chapter of Zhi Gong Tang, and my name is Chen Decheng." A man on the top of the cliff stepped forward quickly and stretched out his hand to Zhao Yiqun, who was obviously the leader.

"Hello, thank you very much for your help." Zhao Yiqun politely shook the other party's hand, and it was indeed very cordial to see his compatriots in a foreign country, especially those who helped the motherland at a critical moment, regardless of their own safety.

"Now that your mission is complete, go back to your quarters, we're going to complete it." Zhao Yiqun then explained.

Chen Decheng shook his head: "We won't go, the hall master instructed us to try our best to assist the army, you see that we are here with some good hands, if your army has any tasks to complete, we can lead the way." We are familiar with the terrain here and can help you very well. ”

Looking at the guards of the few young men in civilian clothes dressed quite neatly all over their bodies, each of them looked shrewd and capable, Zhao Yiqun knew that they came prepared, in the Boston Empire, which was unfamiliar with life, if it was only based on military maps, it would indeed be a little difficult, and if these guides joined, the action would be faster.
