West of Kalimantan and south of the Riau Islands, at 11°33' north latitude and 107°12' east longitude, a submarine is slowly sailing south.

The flag hung high above the control tower was fluttering in the wind, and two sailors were looking around with binoculars.

This is the Lixia-class A-Zi No. 2 ship of the Second Submarine Group of the Nanyang Fleet of the Ming Navy, and they received a telegram four days ago -- to suspend the routine patrol mission and go to the open sea of Sileng on the island of Java as soon as possible to stand by.

In order to get there, they had to sail fast on the water during the day, so they instead hung the rice flag to confuse the Dutch, pretending to be a submarine of the Royal Navy, which can be described as a swagger.

The history of modern naval submarines originates from a series of submarines designed and built by the American Holland, who is known as the father of submarines.

Countries around the world are interested, order Holland submarines, and then develop their own submarines based on them. The proud British Empire, which was more grinding in this regard, scoffed at such "sneaky" weapons, and it was only at the beginning of the twentieth century that they ordered five Holland submarines.

At that time, the Daming Naval Division had just been renamed the Navy, and before the regularization construction was on the right track, some people had already spied on the submarine as indeed a good weapon for coastal defense, and suggested that it be introduced.

However, considering that its own industrial construction has just started, it seems a bit "I want to learn to run before I learn to walk"?

Therefore, it was not until four years before the European war that the Ming Navy ordered four submarines from the British Vickers Company and the French Schneider Company, and required that the latter two be built in the Guangzhou Shipyard and the Shanghai Shipyard respectively, and the two companies would send personnel to guide them.

After the European War, Daming ordered two 900-ton Diana-class medium submarines and a 1,300-ton Lagrange-class large submarine from France for the last time. At this point, after crossing the river with Britain and France, the Ming Navy embarked on the road of submarine design in its own style.

Today's Lixia-class submarine is a cutting-edge large ocean-going submarine that was only put into service last year, with a first-class level except for passive sonar and power systems, with a length of 92 meters, a width of 8.5 meters, and a displacement of 1,570 tons on the water and 2,240 tons under the water.

The powertrain was originally planned to use two 7,200 hp diesel engines, but the actual test found that the noise was too high, so it was changed to four 4,000 hp diesel engines. It is powered by two 950 hp electric motors when sailing underwater. The maximum speed is 21 knots above water and 9 knots underwater.

The oil tank has 360 tons of diesel oil and 10 tons of lubricating oil, with a maximum endurance of more than 12,000 nautical miles. The battery system consists of 180 lead-acid batteries, each weighing 600 kg, capable of supporting the entire boat at a speed of 4 knots for about 90 nautical miles.

The weapon system consists of a total of 6 torpedo tubes in the bow, 4 stern and 2 tubes, carrying a total of 20 16-inch, 512mm Type 30 steam gas torpedoes. There is a 112mm naval gun on the deck and two 12.8mm anti-aircraft machine guns on the conning tower.

Special equipment includes a short-wave communication equipment and a long-wave communication equipment, as well as a "lightning strike element calculator", that is, a torpedo data computer.

"Grass, enemy planes, four o'clock direction!"

"What the hell are you rushing into the streets, bring that tricolor."

A P2Y SEAPLANE BELONGING TO THE DUTCH EAST INDO-DUN AIR FORCE (ML-KNIL) SPOTTED A SUBMARINE HEADING SOUTH IN A SURFACE STATE DURING A ROUTINE PATROL MISSION.

The two pilots in the cabin were a little curious, so they descended to take a closer look.

Seeing the rice-shaped flag fluttering on the control tower, the navigator held the telescope and said, "What are these Britons doing?" ”

The pilot said casually: "Maybe it's also for navigation training?" You look at the diary and the memo, right? ”

"There's no need, trouble."

"You're so stupid."

At this time, the two saw the sailors on the submarine's control tower raising a Dutch flag.

The two sailors tried to keep the tricolor in their faces and steered along the plane, always keeping the flag facing the plane.

The P2Y seaplane circled at low altitude, swung its wings three times in salute, and then continued northeastward.

"Report, the plane went around in a circle and left." One of the sailors turned to the co-captain.

"That's good, half a day and one night today, tomorrow morning will be changed to a diving voyage, and then a floating voyage in the evening, and you can arrive that night."

"Yes."

The Ming Navy's naming of submarines is a level plus a model plus a number, and the level is 24 solar terms, such as the Lixia-class A-shaped No. 2 boat, which is the second Lixia-class A-type.

This was the second time that the Lixiajia No. 2 boat went to sea after entering service, but just seven days after its departure, it encountered an unexpected situation - the captain of the major suddenly suffered from acute appendicitis, and after undergoing emergency surgery in the infirmary on the boat, he was picked up by a seaplane sent by the base.

But the task had to continue, and the whole boat was transferred to the command of the deputy lieutenant Ling Su. But a few days later, they received this strange order.

What are you going to do in the Dutch territory?

"There's a new order." After receiving the message, the telegraph translated it and presented it to Ling Su.

The idle mechanical officer came over, "What's the situation?" Got the task? ”

"Well, let's go pick up a bunch of lost people home." Ling Su said calmly.

In the evening of the day, in the Katarin Hotel......

Zhao Rong and Guo Shenggen, who had outstanding marksmanship, also came to room 0907, and they had just finished reconnoitring the Tadio barracks.

"Sir, these Dutchmen don't know how to train their troops, I ......" Zhao Rong didn't know what words to use to describe what he saw today.

Guards were so lax that the barracks were lined with small stalls and vendors, smoking cigarettes and drinking chilled juice, hiding in the shade of trees or guard towers.

Some well-known vendors can even go in directly after saying hello, and the most surprising thing is that some scantily clad prostitutes actually seem to be entering and leaving their own homes?

After inquiring with people nearby, I found out that Javanese soldiers often used military supplies to pay for prostitution?

This is a common situation, and the Dutch are very troubled by it, and if it is strictly managed, it will lead to complaints and heckling!

In fact, after the colonial authorities decided to reorganize the Dutch and Indian armies, some officers did make up their minds to rectify this terrible situation, but to no avail. For example, last year, a major was jointly "complained" after only strictly rectifying discipline for more than a month.

Because the Javanese soldiers complained about this, they treated their training passively, and even some of the lazy, indulgent Dutch non-commissioned officers were not used to it.

Engineer corporal Wang Mingfa showed a look of "you are kidding me" when he heard this, "Sir Zhao, you are not joking, are you?" And that's the army? Since ancient times, only extremely corrupt soldiers and horses dare to indulge like this, right? ”

Zhao Rong shook his head helplessly, "It's true! ”

The colonial army, they go to suppress the rebellion of the people on Java Island and Sumudara, and there are ghosts if the military appearance and discipline are good!

"But there's nothing to laugh at, how long has it been since our military discipline has improved? It's not fun to laugh at a hundred and fifty steps. Zhou Changfeng waved his hand, and then said, "Let's refine the action plan." ”
