Thunder and lightning are mixed, and heavy rain is like a curtain.

East longitude 29.944, north latitude 126.808.

In this deep sea where there are few commercial ships involved, the humpback whales are like a string of arrows, and they keep moving at a speed of 130 knots.

According to the electronic chart, one hundred and fifty nautical miles further, it is the Miyako Strait between the island of Meguro and Miyako Island.

The Miyako Strait is about 150 nautical miles wide, and hundreds of nautical miles are international waterways for civilian ships. However, no ship is willing to take the middle deep sea channel, and most of them have lighthouses on both sides, and the islands with navigation stations pass by.

This facilitated the humpback whale, Ye Qing prepared to cross the Miyako Strait from the middle, the course was adjusted to a fifteen-degree angle, and headed for the final destination in the waters near Oshima.

The total voyage is 500 nautical miles, and the return is about seven and a half hours, enough for the test of the humpback whale.

When the humpback whale returned to Longxitan, Zhongyun also just ushered in a new dawn.

......

The torrential rain covered hundreds of nautical miles, and in the distant Mongko Strait, it is still a good weather with a rare moon.

At 11:00 local time, the Coast Guard is located at the security headquarters of the Miyako Strait and is undergoing routine night cruises.

The Coast Guard has 11 sea areas, which are responsible for the Miyako Strait. Both the staffing configuration and the number of patrolling ships are among the top 11 areas. Because the Miyako Strait is a very important waterway, both for them and for China.

These years, the country has always emphasized the demilitarization of the Miyako Strait, trying to prevent any national warships or military aircraft other than the United States from passing over the strait.

So patrols can't be less, especially at night.

The pl-grade [Hayakawa patrol ship] newly allocated by a security guard is patrolling from south to north along the widest sea area of ​​the Miyako Strait.

The pl class belongs to the kiloton-class patrol ship. This kind of security hall has the most advanced technology and the shortest installation time, especially strengthening the search and identification ability of the ship.

The Hayakawa is the eighth of the nine construction projects, and it has been less than two years since it was launched.

When Hayakawa patrolled a third of the line, it was about to approach the central channel.

The captain of the command room, Miyamoto Yamaguchi, suddenly received a report from the radar operator, saying that in the direction of seven o'clock ahead, there was a large unmarked ship at the Jiuhaili of the ship, which was rapidly moving towards the middle of the strait.

The unmarked ship is to close the GPS positioning and not report the travel route to the navigation station of the sea area, deliberately concealing its illegal ship.

Because of the problem of the curvature of the earth, no matter how advanced the ship-borne radar is, the detection radius of the ship will not exceed 40 kilometers. Therefore, in the vast sea, not all ships like to abide by the law, nor all legal vessels, are willing to keep themselves in a position to be positioned.

Of course, the AWACS is not limited by the curvature of the Earth.

It’s just that the AWACS is more expensive than gold, and only a few countries in the world have it. Dozens of early-warning aircraft purchased from the United States have been willing to let it patrol the sea.

"Unknown international ship?" Captain Gong Benyangshan glanced at the electronic chart, frowning asked: "calculate the latitude and longitude and the speed of the ship."

The radar operator sitting opposite is quickly reporting the detailed data.

This is an illegal ship with a radar characteristic of a civilian ship. The ship should be between 3,000 and 5,000 tons, and the speed is 27 knots...

"The freighter can't run for 27 knots. It seems to be a large illegal fishing boat. This speed is mostly their maximum speed, indicating that they are not far from the destination." Captain Gong Benyangshan was annoyed: " In front of Daguyuan Island, the fishery resources are the most abundant. The **** fishermen dare to steal fishing during the fishing season."

"Perform the radar lock, adjust to the maximum speed to catch up with them, enter the two nautical miles and then warn through the public radio channel, stop the boat, and warn the shooting."

In the night, the Hayakawa patrol ship quickly sprayed black smoke from the flue. The sea surface radar at the top of the island is fully open and the wheels rotate as fast.

The Hayakawa patrol ship has a maximum speed of 33 knots and it takes only one and a half hours to catch up with a 27-speed fishing boat.

Once caught up, a huge amount of fines will make all members of the Hayakawa patrol boat laugh.

In the radar control room, on the pale green radar screen, there is a triangular sign that firmly locks the illegal ship, and the latest parameters are constantly corrected at 0.5 second intervals. This is a chase of cats and mice. There have never been illegal fishing boats. They can escape from the lock of the Hayakawa patrol ship.

"Drip ~"

At this point, the radar console suddenly sounded a tone with a new target entering the scan radius.

At the same time, the radar computer automatically gives the distance parameter of 22 nautical miles apart. At this time, the Hayakawa patrol ship was within 22 nautical miles of the radius, only the illegal fishing boat, and the unknown new target that had just entered the field of vision.

After 0.5 seconds, the radar correction information is still twenty-two nautical miles apart.

At the same time, the radar operator reports the location of the new target to the command center, allowing them to contact the nearby navigation station to assist in inquiring about the location of the ship that is registered.

Few ships will choose to sail in the center of the Miyako Strait, because the north is the endless North Pacific. Since the patrol ship of the Hayakawa patrols at night, it will of course choose ships with scarce seas and specialize in vessels that are not willing to take the normal course.

The navigation stations are all electronically operated. On a huge electronic chart, all the recorded tracks of the passing ships are listed. Therefore, in less than ten seconds, the other party gives a reply in the target area without the passage of the record vessel.

Ok, it’s another illegally navigable ship.

When the radar operator sets the target to the target, it is very imaginative. According to the position of the target, the ship is driving in their direction. Then they chased the illegal fishing boat and then turned around and caught the boat.

Lock the target and the time to the radar to give details no more than one second.

The radar operator is ready to report to the captain, but at the next moment, he hears a harsh alarm from the radar console.

"Warning ~"

"Warning ~"

"I found unidentified ultra low altitude flying objects."

The radar operator is somewhat confused to see the warning message on the screen.

Tens of seconds ago, the unknown ship had just entered the radar detection range, which was 22 nautical miles away.

Now the radar computer gives detailed data, the unknown target, the radar reflection feature can not be identified as civilian or military vessels, and even it is not a ship at all.

Speed...

The speed is 130 knots, 66m/s.

At this time, the operator was scared to recall that the Hayakawa was the most advanced patrol ship installed by the Security Department. The ship's ops-28d sea surface radar, copied directly from the Ai-type frigate, not only can search and identify surface vessels, but also has the ability to identify ultra-low-altitude aircraft, that is, sea-swept anti-ship missiles.

An object with a speed of 130 knots and an advance of 66 meters per second is not a flying object. What can it be?

Everyone in the command center stopped working and watched the radar operator slyly.

"Damn, what?" The Hayakawa patrol ship is a small ship, and the electronic equipment control systems are concentrated in one cabin. Captain Gong Benyangshan ran to the radar station that kept warnings. His look was ugly. He really thought that this patrol ship had encountered an unknown enemy.

"This..." The radar operator was amazed. At this moment he also saw the volume of the flying object given by the radar. Although no match was found in the database, the computer ambiguity gave a judgment that the object was over 5,000 tons.

"Is it... this is a ship?" The radar operator muttered to himself, but the next second, when the radar updated the data, the unknown object suddenly disappeared.

"Ah?" The operator and the captain squinted. The original two tracking targets became one. The illegal fishing boat was still in the list, but the edge of the target seemed to never appear.

After the alarm disappeared, the silence continued for half a minute in the command center.

The radar has updated 60 times of data, and the target that the radar can't distinguish is never seen.

The target cannot disappear in an instant, and no ship can reach a speed of 130 knots.

The aircraft is even less likely, so large, unless it is an alien spacecraft.

"Captain, maybe...the radar is malfunctioning." The radar operator subconsciously tapped the device.

""I...the captain, if you are not at ease, you can contact the headquarters and ask them to send a helicopter search. ”

Captain Gong Benyangshan frowned, and his heart was more inclined to radar false positives. This situation is not very common, but it is not uncommon. Last year, the patrol ship of the island after the island had a big joke about radar false positives.

The Houdao Island District is close to the Thousand Islands, which is particularly close to Russia. During a patrol, the local patrol ship's pair of sea radars suddenly scanned a circular unidentified target with a diameter of 800 meters and hovered at an ultra low altitude.

At that time, the radar operator was far from the calmness of his men. The guy quickly grabbed an emergency call to report to the headquarters, saying that ufo was coming to the Japanese waters.

In the end, the airborne self-propelled aircraft took off two urgently. After the fuel was flying fast, the ghost shadow did not find one.

If it weren’t for the last time someone had unintentionally looked at the ship’s surveillance screen of the patrol ship, it would not be possible to become a mysterious mystery that could not be solved.

what's the result?

The result was that the wind and waves reached level six on the day, and a piece of foil for baking bread in the patrol ship's kitchen was somehow blown into the sky by the wind. The good electromagnetic reflectivity of the foil paper allowed the radar that could have detected the volume to make a mistake, and was finally turned into a ufo report by the rookie operator who was not cool.

Captain Gong Benyangshan certainly cannot make this ridiculous patrol ship, but the radar that lasted for dozens of seconds found the time, but let him balance the radio and then grabbed the radio.

"Here is the Hayakawa patrol ship. We found a target anomaly on the patrol. We were unable to judge the target and asked the headquarters to perform the helicopter search after receiving the abnormal target position."

"The search range is fifty nautical miles."
