Development of productivity started in 1981

Chapter 79: Okinawa Trip (asking for monthly ticket)
Before setting off, Wang Jiankun measured the distance from the mouth of the Yangtze River to Okinawa from the map. If one walks along the great circle of the earth's curved surface, it would be about 820 kilometers.

At the speed at the snorkel depth, it will take about 15 hours. Of course, it is impossible to travel at the highest speed the entire time. We need to rest and test the missiles we are preparing to manufacture, so it is estimated to take more than 20 hours to arrive.

It was night time, and Wang Jiankun drove the submarine to a maximum speed of 30 knots. After finding the right direction, he headed straight for Okinawa.

Wang Jiankun turned on the passive sonar in the submarine. When the sonar detected a ship within 3 nautical miles, the connected autopilot system would sound an alarm to remind Wang Jiankun, giving him time to react and drive the submarine deeper.

Along the way, Wang Jiankun used his superpowers to collect uranium. At this time, because the range of his superpowers had increased to 120 meters in length, width and height, his efficiency in filtering and collecting uranium was greatly improved. At a speed of 30 knots, he could collect 2.4 kilograms of uranium per hour.

After sailing for more than an hour, they were almost 1 kilometers away from the mainland coastline. Wang Jiankun began to mobilize elements to manufacture a small remote-controlled aircraft to be used as a target aircraft.

He placed many kinds of elements in the submarine, including copper, iron, aluminum, zinc, carbon, silicon, chromium, molybdenum, etc. He first mobilized iron, carbon, chromium, molybdenum and other elements to manufacture a small turbojet engine. After the manufacturing was completed, he tested it on the submarine deck. The generator started successfully. Because it was used as a target machine, long-term use was not considered. The experiment showed that it could start and run stably for 1 minute.

Next, he manufactured the body of the remote-controlled aircraft. Taking into account the lightness and complexity of the element combination, Wang Jiankun directly made a stainless steel frame and carbon fiber skin and wings. The appearance of this remote-controlled aircraft was based on the F-15.

Of course, as a target aircraft for testing the individual air defense missile designed by Wang Jiankun, it does not need to reach supersonic speed for the time being, and a speed of 8 kilometers per hour will be enough.

As long as the missile can catch up with and hit this target aircraft, my uncle will have an effective air defense umbrella, and his base will not be afraid of national-level interference.

Because there are many mountains over there, the air defense missiles are deployed on the mountainside or on the top of the mountain, and equipped with warning radars. Fighters and bombers that cannot fly supersonicly have no way to attack my uncle's base. Supersonic flight is very dangerous in mountainous areas, and only top pilots have the ability to fly supersonicly at low altitudes in mountainous areas.

After the fuselage was completed, Wang Jiankun installed the engine he had just made, and then made the remote control handle and antenna.

Because the target aircraft was on a submarine that was more than 9 meters long and there was not enough runway for takeoff, Wang Jiankun added two rocket boosters to the target aircraft and then made a temporary takeoff bracket in front of the submarine.

Then we will manufacture individual air defense missiles.

This air defense missile is modified based on the Perry-class air defense missile. It adopts infrared guidance mode. The seeker is an indium antimonide multi-element array infrared detector with an information processing device. It has the characteristics of high sensitivity, comprehensive target attack and strong ability to withstand infrared interference.

And because Wang Jiankun used superpowers to create it, the purity of the indium antimonide multi-element array is higher, the array can be made smaller and more numerous, and the processor used has very good performance. Therefore, according to Zhizi's simulation test, as long as the target is locked, the aircraft that has not entered supersonic speed will be bitten and shot down.

Because it was the first missile to be manufactured, caution was required. Wang Jiankun set aside a little energy to capture the uranium element, and concentrated all his energy on manufacturing this individual air defense missile.

It took more than three hours to finally complete the missile and the corresponding launch device. The completed missile was fixed on the rack on the rear deck.

Wang Jiankun planned to name this missile Donghai 1, and engraved the DH-1 logo on the launch mechanism shell and missile warhead.

The design parameters of DH-1 are as follows:
Launch tube length 1400 mm
Launch tube mass 3.1 Kg
Maximum missile diameter 75 mm
Missile length 1380 mm
Missile mass 11.5Kg
Wingspan 283 mm
Warhead mass 3.5 Kg
Weapon system combat mass 21.8 Kg
Range 300-5000 M
Height 50-2000 M
Reaction time 5 s
Maximum speed: Mach 1.7
The above is the data obtained from the simulation test after Zhizi’s design was completed, so Wang Jiankun still needs to manufacture a physical product for testing.

At this time, the submarine has arrived in the central area of ​​the East China Sea, 300 kilometers away from the mainland coastline and more than 400 kilometers away from the US military base in Okinawa. There should be no danger in testing here.

To be on the safe side, Wang Jiankun installed friend-or-foe identification devices on the target aircraft and the missile. The missile will only detonate its warhead when it is within a certain range of the target aircraft, ensuring that no aircraft that enters the area will be accidentally injured.

After all preparations were done, Wang Jiankun reduced the speed of the submarine to 10 knots. At this time, the wind and waves on the sea were relatively small, and the sky was filled with a crescent moon and stars.

Wang Jiankun first released the target aircraft and pressed the start button. The rocket boosters ignited first, emitting two long tail flames, pushing the target aircraft into the sky.

The engine of the target drone that left the launch pad was also started. Under the dual effects of rocket thrust and engine thrust, the speed and altitude of the target drone quickly climbed. The booster rocket separated from the target drone after burning for 15 seconds.

Wang Jiankun checked the target aircraft's information on the radar screen, which showed that the target aircraft's speed had reached 480 kilometers per hour and its altitude had reached 800 meters, and it was circling the center of the submarine with a radius of 1 kilometer.

In order to test the speed and pursuit altitude of the missile, Wang Jiankun carefully adjusted the flight status of the target aircraft with the remote control handle.

Let it accelerate slowly, and when it accelerates to 700 kilometers per hour and reaches an altitude of 1800 meters, Wang Jiankun sent the last control command to the target aircraft, letting it fly in an arc from the right front to the left front of the submarine, and let it rise to 2000 meters, with the engine accelerating to full speed.

Then he came to the rear deck of the submarine, turned on the aiming device, and the infrared seeker quickly locked onto the target aircraft. The infrared characteristics of its tail nozzle in the night sky were clearly displayed in the sight.

Without hesitation, after the missile made a "beep" sound of locking, Wang Jiankun pressed the trigger, the missile ignited, and flew out of the missile tube quickly.

After the launch, Wang Jiankun returned from the rear deck to the radar screen to observe. The missile, which had been aimed at the infrared feature, no longer needed guidance and would automatically pursue the target. Moreover, it was not clear at night with the naked eye, because even if there were a sky full of stars and a crescent moon, it would be impossible to see the missile and the target aircraft at an altitude of nearly 2 kilometers.

After 10 seconds, Wang Jiankun saw that the small dot showing the target aircraft suddenly became a little bigger, and then quickly disappeared.

This means that the missile has successfully hit the target aircraft. At the last moment, the target aircraft was traveling at a speed of 870 meters per hour, flying at an altitude of 2300 meters, and was more than 5200 meters away from the submarine. This shows that the missile's altitude and range fully meet the design requirements.

In order to obtain more data, Wang Jiankun built four target aircraft and four missiles in the second half of the night, and then tested them one by one.

One of the last four missiles missed the target, and the missile hit rate obtained in this round of testing was 4%.

The performance of the missile has been basically tested and it can hit aircraft within 40 meters to 2400 meters and 300 meters to 5500 meters.

Because it is a supersonic missile, except for a limited number of aircraft used by a few major countries, other aircraft cannot fly supersonically, so the air defense missile designed for my uncle is completely sufficient for now.

We will wait and see when the time comes. If we can buy or lease an island, we can manufacture more types of missiles with greater power there.

After the test was completed, Wang Jiankun increased the speed to 30 knots. Near midnight, he measured the position again based on the starlight to ensure that he was on the correct route.

After the sun rose, Wang Jiankun drove the submarine to the snorkel depth and still maintained a speed of 30 knots.

At around 3 p.m., Wang Jiankun raised the submarine to periscope depth and built an infrared detector on the periscope to observe whether there were any patrol aircraft in the sky.

After confirming that there were no planes flying at low altitude, he piloted the submarine to the surface, then calculated the latitude based on the position of the sun and the distance traveled based on the gyroscope data. According to his calculations, he should be not far from Okinawa at this time.

After confirming that there were no planes in the sky, Wang Jiankun made a radio detection and positioning device on the deck. Because he had collected the U.S. military's radio communication codes before, Wang Jiankun was able to quickly monitor and decipher the U.S. military's radio transmission location in Okinawa after the device was completed. Of course, the island's broadcast signals were also detected.

Based on the guidance of these two radio signals, Wang Jiankun can accurately find the correct course.

The submarine was sunk, leaving the radio receiving antenna exposed above the sea, and then it sailed towards Okinawa at a speed of 10 knots.

After dark, Wang Jiankun used an infrared device to detect the sky and surfaced the submarine again. At this time, he could see lights in the distance from the submarine bridge. He confirmed it with a radio monitoring device and found that it was the main island of Okinawa. The US Navy base was near the East China Sea. The US military was less vigilant in this direction. After all, the country across the sea currently did not even have a large destroyer assigned to the East China Sea area. There were only some small ships that did not dare to sail far, so the duty personnel at the base were sleeping soundly, the active sonar was not turned on, and the passive sonar monitor was dozing off, otherwise Wang Jiankun's submarine might be discovered.

When Wang Jiankun manufactured this submarine, he only referred to some appearance data collected at the time. As for how to reduce noise, he just manufactured it according to the principle. It had not undergone large-scale testing and there was no physical reference, so the decibel level was still 10 decibels at a speed of 93 knots.

Seeing the lights in the distance, Wang Jiankun knew that they had entered the middle defense circle of the US military base, so he quickly reduced the speed to 5 knots and turned off the diesel engine, completely powered by batteries.

It moved forward little by little, not directly towards the US military base, but towards the north.

As the water depth gradually decreased, Wang Jiankun began to use his superpowers to explore the seabed terrain, preparing to let the submarine sink to the bottom of the sea while he dived into the US military base.

Because he was diving alone, the base's monitoring system was very difficult to detect, and he only needed to get within 120 meters of the ships, weapons and equipment, and command organizations in the base to project all the information into his mind.

When the water depth was only more than 20 meters, Wang Jiankun drove the submarine back and forth and found an underwater groove with a width of more than 10 meters. On both sides were gradually rising underwater hills. The top of the mountain might be only a few meters away from the sea surface at low tide. It was impossible for any ship to pass through this terrain with underwater reefs, so it was safer to park the submarine here.

He carefully drove the submarine to the bottom of the sea. After the stirred-up mud and sand settled, Wang Jiankun began to prepare to leave the submarine.

At the front of the submarine, Wang Jiankun has reserved a passage for exiting the submarine. The diving equipment has also been manufactured and tested in the Yangtze River. There is also a small electric booster to assist in moving forward.

In the front cabin, he first put on warm clothes, then put on a diving suit, carried the oxygen tank and put on the oxygen mask. He held the driver in one hand and pressed the water inlet switch with the other hand. The water slowly filled the front cabin. After the pressure inside and outside was consistent, Wang Jiankun slowly opened the cabin door.

After getting out of the boat, Wang Jiankun first adapted to the dark underwater environment for a while. Fortunately, he had super powers that allowed him to observe the surrounding situation, otherwise an ordinary person would definitely be lost.

Use your superpowers to close the hatch, then start the boosters and slowly swim upwards.

After emerging from the sea, Wang Jiankun put down his oxygen mask and breathed in the cold and humid air for a while.

While breathing fresh air, he was also observing the direction, looking at the top of the warship exposed in the distance, and confirming that that direction was the dock where the warship was docked.

He put on his oxygen mask again and swam towards the base dock using the booster.

It was past 10 o'clock at night. The dock was quiet with only a few people walking around. All the ships docked at the dock were turned off, and searchlights on the shore occasionally swept over the warships and the surrounding waters.

More than 800 meters away from the pier, Wang Jiankun sank more than 3 meters below the sea surface and swam forward, so that people on the shore would definitely not be able to find him.

As he got closer to the berth, Wang Jiankun explored more and more things. The first was the sonar laid on the seabed, which he thought could be used as a reference and projected into his mind.

When a large outline of a ship's bottom appeared in his mind, Wang Jiankun knew that he had found something good. He continued to swim forward, and the structure of the warship was projected into his mind bit by bit.

By the time Wang Jiankun had reached the bottom of the warship's hull, he had not yet fully projected the warship into his mind, which meant that the warship was at least 120 meters long.

Moreover, looking at the middle and upper parts of the warship in his mind, Wang Jiankun discovered that it had the shape of an airplane, and the upper part was a flat deck. According to the information Wang Jiankun had heard and collected, this should be an aircraft carrier.

Wang Jiankun swam half a circle around the giant ship, projecting its entire inside and out into his mind, and knew that this was a nuclear-powered aircraft carrier because Wang Jiankun was very familiar with the uranium element in the reactor.

Looking at the high abundance of uranium 235 in this aircraft carrier, he wanted to extract it all, but reason told him that as long as the elements in the reactor were moved, it would definitely set off the reactor alarm. Then this trip to Okinawa would not be perfect, and it would be even more difficult to come in again in the future.

After projecting this nuclear-powered aircraft carrier, Wang Jiankun asked Zhizi to quickly build a model of the aircraft carrier to study its power system, structural design, and the several types of aircraft on the aircraft carrier, all of which were good things worthy of study and reference.

In the shadow of the aircraft carrier, Wang Jiankun surfaced, looked at the aircraft carrier deck floating above his head, felt the oppression of this man-made giant, and then looked front and back of the aircraft carrier and found that a warship more than 130 meters long was docked at the rear berth.

So he dived again and swam towards the warship, launching one warship after another, a total of 5 large warships (over 4 tons) and 8 small warships, as well as several tugboats and fireboats, and then he reached the submarine dock, where a nuclear submarine was moored.

Wang Jiankun did not hesitate to project the big black fish into his mind and asked Zhizi to quickly allocate computing power to study the appearance of the submarine and the noise elimination device so that Wang Jiankun could transform his small submarine.

Wang Jiankun explored the dock and could almost open a warship and aircraft museum in his mind, so he dived out of the dock and swam towards the place where the submarine sank.

On the return journey, he swam about 10 meters underwater the entire time. With the help of electric boosters, he moved forward quickly according to the seabed topography map projected in his mind. In less than 20 minutes, Wang Jiankun arrived at the place where the submarine sank.

It was still early spring and the sea water was very cold. Although I had special cold-proof underwear and diving suits, I couldn't stand staying in the icy sea water for so long, so I used my superpowers to quickly open the entrance and exit of the front cabin, and quickly drained the sea water after entering.

After taking off his diving suit, Wang Jiankun came to the living cabin and used the microwave to heat up a can of luncheon meat and a bowl of rice that he had previously frozen.

While eating, Wang Jiankun asked Chieko about the progress of her research on submarine silencing. After learning that she already had a preliminary plan, Wang Jiankun quickly finished the food in front of him and then checked the plan given by Chieko.

The original plan was very simple, which was to install a layer of sound-absorbing tiles on the hull of the submarine. Of course, this was not an ordinary tile, but was made of synthetic rubber. It must be able to work for a long time in seawater without being corroded, and the installation method and glue used were also special.

Wang Jiankun didn't think too much about it. The installation method and glue were exactly the same as those of the big black fish. The rubber composition was also exactly the same, except that the thickness was slightly changed. The appearance of the submarine was also slightly adjusted to make it easier to stick the anechoic tiles on. The shape was also designed to be able to emit sonar signals.

After the manufacturing was completed, Wang Jiankun looked at the time. It was already past 2 a.m. This trip to Okinawa had been largely successful. A large amount of technology had been obtained, especially aircraft carriers and nuclear submarines. These were the world's top weapons and equipment, without a doubt. Even the Red Empire, the Soviet Union, did not have such large aircraft carriers in service.

其上面的多种舰载机也是最先进的，比如有F14、A-7、A-6、EA-6B、S-3、E-2、C-2、SH-3等等。

Among them, the F14 "Tomcat" fighter is the world's first variable-sweep wing fighter, as well as the most advanced EA-6B "Prowler" electronic attack aircraft and the E-2 "Hawkeye" early warning aircraft.

The technologies in these three aircraft will take Wang Jiankun a long time to study. When his uncle's territory expands, he will build a few unmanned versions and test them there.

He got samples of the electronic equipment, control programs, etc. inside, as well as the maintenance manual. If it were not for his insufficient self-protection capabilities, Wang Jiankun really wanted to give it a try in manufacturing it.

There is also a flight simulator on the aircraft carrier, which is used for pilots to conduct pre-go-around tests when they make mistakes in driving. Wang Jiankun plans to go back and make one so that he can use it to learn how to fly first. When the aircraft is built in the future, he can quickly get started.

As for the other aircraft, Wang Jiankun checked the information compiled by Zhizi and learned that the A-6 and A-7 were attack aircraft, which Wang Jiankun felt were not practical. The S-3 was a "Viking" anti-submarine aircraft, the C-2 was a "Greyhound" carrier-based transport aircraft used to quickly and irregularly transport supplies and personnel to ships, and the SH-3 "Sea King" helicopter was a carrier-based combat helicopter.

These are also worth studying, and some of the above technologies can be used in the future. Generally speaking, except for land equipment tanks and armored vehicles, Wang Jiankun can copy other weapons, even strategic nuclear missiles, because there are several in that big Black Fish, and two of them contain nuclear warheads, and they are hydrogen warheads.

Taking advantage of the late night, Wang Jiankun simply tested that the decibels of the submarine's underwater electric drive had dropped below the background noise of the ocean. Then he drove the submarine away from Okinawa and headed for home with a head full of trophies.
