On September 5, the PJP set sail from Haiphong port with 2,500 tons of tungsten sand.

The location of Haiphong Port is deep in the Beibu Gulf, two to three hundred kilometers north of Sanya, the southern tip of Hainan Island. In this kind of position, it is actually not difficult for the army fleet to blockade it.

The captain of the PJP, who is now Huang Zhonghua, had already been promoted to captain of the pickup, but because the last time the business in Germany was done well, he took on the business again. Li Guang has already assured Huang Zhonghua that this is the last time he will do business. If it is done well, when you come back, you will at least be the captain of the Jairian torpedo boat, or even the captain of the second one.

Now the ranking of warships is very clear from top to bottom of the Maritime Resistance Force, and the pickup number is not small in terms of displacement, but it is not a battleship at all, but a training ship or supply ship. The Baxia and the Jairus are equally famous, and if he can be the captain of the Jairus, then he Huang Zhonghua can really be regarded as a high-level officer of the Navy of the Naval Resistance Army. Huang Zhonghua is naturally looking forward to this.

Huang Zhonghua is well aware of the difficulty of this mission. I don't know how many submarines are staring at the PJP.

Originally, the Pixiu was ready to respond as early as September 3. However, Huang Zhonghua was delayed for a day in order to wait for a French freighter next to him.

In any case, now Indochina is still a French colony. With the French freighter, the devil would not have just gone to sea to attack.

The devil's submarine is now unknown, but the Pixiu is less than two nautical miles away from the PJP at this time.

The PJP, with six 75mm guns and four heavy machine guns, has been on the lookout since it set sail. On the top of the bridge and around Huang Zhonghua, there were twelve observers.

At this time, the most nervous was the fleet commander Zheng Xuechang, who was now on the sea more than 100 nautical miles south of Haiphong with the Baxia and Pika, as well as the only reconnaissance plane.

He was well aware of Li Guang's plan, and this time the 2,500 tons of tungsten ore were exchanged for more than 200 tons of explosives. The domestic value is about two million oceans, if according to the price of the last trade is more than three million oceans, and if it is according to Li Guang's estimate, it should be able to sell for four million oceans this time, and now that Britain and France have declared war on Germany, the Germans are certainly willing to pay a high price for this. And this batch of tungsten sand, Li Guang has already paid for it with more than 200 tons of explosives, which means that if the tungsten sand ship is blown and sunk, then Li Guang will lose nearly one million US dollars.

One million dollars is not a small amount for the current Maritime Resistance Force, which can build a medium-sized submarine that is being designed.

Not only that, Li Guang's arrangement of this money is what Zheng Xuechang is most concerned about. Li Guang wanted to use this batch of tungsten ore to buy a German man 6,800 horsepower diesel engine.

The 6,800 hp diesel engine Zheng Xuechang asked about the price in Germany last time, about 600,000 US dollars, but the problem is that the Germans do not sell this diesel engine to the outside world at all. This is the most advanced diesel engine in Germany and currently the most powerful diesel engine in the world.

During the entire World War II, diesel engine technology was not more advanced than steam turbines, nor was it mature, but diesel engines used on warships had a unique advantage, that is, the weight and volume were slightly smaller than that of steam turbines, and the amount of diesel consumed was significantly less than that of burning oil.

For example, the Baxia, because of the use of diesel engines, has a displacement of five or six hundred tons, but its combat effectiveness is no worse than that of a destroyer with a displacement of one thousand tons. If you can buy a diesel engine with 6,800 horsepower, then even if you can build a light cruiser or destroyer, or a coastal defense ship with a displacement of only two or three thousand tons, the firepower and protection will definitely not be worse than that of a cruiser of 5,000 tons.

The thermal efficiency of diesel engines and oil-fired boilers is not at all in the same grade, and a battleship with the same displacement and the same endurance, a battleship powered by a diesel engine only needs about one-third of the fuel reserves of a battleship powered by an oil-fired steam turbine. This item is extremely important for battleships.

The Baxia can guarantee a range of 2,000 nautical miles with only 60 tons of fuel, but if it is a warship of this class with a fuel steam turbine, it must carry at least 200 tons of fuel. The carrying of fuel not only wastes the displacement of the warship, but also complicates the redundant structure of the warship, after all, fuel is a danger to oneself in battle. According to estimates, if an additional 100 tons of fuel oil are carried, the displacement of the warship will be at least 300 tons higher.

The hull is large, the cost and technical difficulty have skyrocketed, and the current shipbuilding capacity of the Uruguayan shipyard can only build a 2,000-ton warship if it is not at risk.

It can be said that as long as the road of purchasing high-power diesel engines is cut off, it will be difficult for the Maritime Resistance Army to equip a real destroyer or cruiser, and can only continue to build gunboats and torpedo boats. Torpedo boats and gunboats are difficult to adapt to ocean-going operations, and the Baxia can run to the South China Sea, although it is related to its low center of gravity and design, but more importantly, it comes from the support of the pickup and JPJ.

In addition, a gunboat of this displacement, even if it is built with a very low center of gravity, cannot be compared with a cruiser of several thousand tons, and since it is unstable, then the accuracy of shooting is naturally very poor. Of course, the weakness of the artillery fire is its fatal shortcoming.

Li Guang also gave another set of plans, if you really can't buy 6,800 horsepower diesel engines, then you can only use 2,500 diesel engines to use in combination, but there are more diesel engines, there are more fault points, and the space occupied is also large, which is not the best choice.

All in all, this high-power diesel engine is simply the hope for the Maritime Resistance Army. And Li Guang's budget is also very generous, if the tungsten sand worth four million oceans is not enough to buy four, then he can add another one million dollars. But no matter how much money there is, it will be difficult for Li Guang to make up for a while.

Li Guang has now found a way to send money to Germany, Uruguay does not have a German consulate, but Argentina across the river has a German consulate, as long as the money is handed over to the consulate, a little handling fee is paid. It's so much more convenient than it used to be.

Now the Overlord is on standby, and both the observation post and the sonar soldiers are closely watching the movements around them.

Zheng Xuechang's choice of this place of response is actually very dangerous, if he can't kill the submarine at the first time of the war, then the devil who reacted will definitely send a fleet to support. The Devil's fleet is perfectly capable of intercepting the PJP before it escapes from the Gulf of Tonkin . What's more, there are also fighters of the Chinese army that are an even greater threat.

The key to winning this battle is that once the war starts, the submarines of the Chinese army must not be allowed to surface again. Only when they float up can the devil send a telegram, and the devil underwater cannot send a telegram.

At present, the Baxia is moving in a small Z-shape on the sea surface, even in order to avoid being tracked by the submarines of the Japanese army, but also to be able to detect the submarines of the Japanese army.

Zheng Xuechang secretly calculated in his heart: the PJP departed at six o'clock in the morning, and according to the speed, it should arrive here at noon. And this is also the most likely ambush site for military submarines. Early on, Zheng Xuechang had already ordered the water reconnaissance plane to take to the air and reconnoiter along the route of the PJP.

Since this is a fighter made in the world, this fighter is in military livery at this time, and the little devil will not have any suspicion even if he finds it. Zheng Xuechang even hoped that after the devil's submarine was discovered, he would float up and say hello. But obviously, the devil is not so stupid.

The reconnaissance plane did not find anything, but only made contact with the PJP. Due to the bad sea conditions, and the pilot Liu Gensheng is also a second-hand knife, his flying skills are still extremely rough, so he did not dare to continue to expand the scope of searching.
