Monster Factory Chapter 829: : The disappearing target
Thunder and lightning are blowing, and the rain is like a curtain.
East longitude 29.944, north latitude 126.808.
In this deep ocean where there are almost no commercial ships, the Humpback Whale keeps the speed of 130 knots straight ahead like an arrow from the string.
According to the electronic chart, one hundred 50 nautical miles ahead is the Miyako Strait between Ryukyu Island and Miyako Island.
The width of the Miyako Strait is about one hundred 50 nautical miles, of which hundreds of nautical miles are international waterways, which can be used for harmless travel by civil ships. However, no ship is willing to take the middle deep sea channel, and most of them pass by the islands with lighthouses on both sides and navigation stations.
This provided convenience for the humpback whale. Ye Qing was going to cross the Miyako Strait from the middle, adjusting its course at a fifteen-degree angle, and heading towards the final destination, Sea Area near Ogasa Marushima.
The total voyage is 500 nautical miles, and it takes about seven and a half hours to turn around, enough for the humpback whale to test.
In this way, when the humpback whale returns to Dragon Creek Beach, Zhongyun also just ushered in a new dawn.
……
This torrential rain covered hundreds of nautical miles, and the sky over the Miyako Strait in the distance was still good weather with sparse stars.
At night local time 11:00, Coast Guard is located at the security headquarters of the Miyako Strait, and is performing routine night cruises.
Coast Guard has 11 maritime jurisdictions, and the branch responsible for the Miyako Strait is at the forefront of the 11 jurisdictions, both in terms of staffing and the number of patrol ships. Because the Miyako Strait is a very important channel, both for them and for China.
In recent years, Japan has always emphasized the demilitarization of the Miyako Strait, trying to prevent any country military vessel or military aircraft except USA from passing over this strait.
So patrols cannot be less, especially at night.
A PL-class [Hayakawa patrol ship] newly allocated by the Security Agency is patrolling from south to north along the Sea Area, the widest of the Miyako Strait.
The PL class is a thousand-ton patrol ship, the most advanced technology of the Security Department, and the shortest installation time. It has especially strengthened the ability to search and identify ships.
This Hayakawa is the eighth ship in the nine-ship construction plan and has been launched in less than two years.
When the Hayakawa patrolled one-third of A-List road, it was approaching the central strait.
Yoyama Miyamoto, Captain in the command room, suddenly received a report from the radar operator that at seven o'clock ahead, nine nautical miles from the ship, there was an unmarked large ship, which was driving quickly toward the middle of the strait.
Unmarked ships, that means turning off GPS positioning, not reporting travel routes to the Sea Area national navigation station, and deliberately concealing their illegal ships.
Because of the curvature of the earth, no matter how advanced the shipboard radar is, the detection radius of the ship will not exceed forty kilometers. Therefore, in the vast sea, not all ships like to be law-abiding, and not all legal ships are willing to keep themselves in a state of being positioned.
Of course, the early warning aircraft is not limited by the curvature of the earth.
The merely early warning aircraft is more expensive than gold, and worldwide is only owned by a few countries. Japan owns dozens of early warning aircraft purchased from USA, how can it be willing to let it patrol the sea.
"Unidentified international ships?" Captain Miyamoto glanced at the electronic chart, frowned and asked: "Calculate the latitude and longitude and the ship's speed."
The radar operator sitting opposite quickly reported detailed data.
This is an illegal ship with a radar characteristic of a civilian ship. The ship should be between 3,000 to 5,000 tons, with a speed of 20 seven knots...
"cargo ship can't reach the speed of 20 at seven knots. It seems to be a large illegal fishing boat. This speed is probably their maximum speed, indicating that their destination is not far away." Captain Miyamoto Yoyama some furious said: "Only Ogasawa Island has the richest fishery resources ahead. These **** fishermen dare to steal fish during the fishing ban."
"Launch the radar, adjust to the maximum speed to catch up with them, and warn through the public radio channel after entering two nautical miles. If you don't stop the ship, you will warn you to shoot."
The Hayakawa patrol ship in the dark, soon burst of black smoke from the flue. The sea surface radar power on the top of the island is fully turned on, and the wheels are spinning fast.
The Hayakawa patrol ship has a maximum speed of 30 three knots, and it only takes one and a half hours to catch up with a fishing boat with a speed of 20 seven knots.
Once caught up, the huge fine can make all members of the Hayakawa patrol ship bend over with laughter.
In the radar control room, on the light green radar screen, there has long been a triangle mark firmly locked to the illegal ship, and the latest parameters are constantly revised at 0.5 second intervals. This is a cat and mouse pursuit, and there has never been an illegal fishing boat that can escape from the lock of the Hayakawa patrol ship.
"dī dōng ~"
At this moment, the radar console suddenly sounded a warning tone that a new target entered the scanning radius.
At the same time, the radar computer automatically gives the distance parameters between the two 20 two nautical miles. At this time, within two nautical miles of 20 within a radius of the Hayagawa patrol ship, there was only the illegal fishing boat and the unknown new target that had just entered the field of vision.
After 0.5 seconds, the radar corrected the information and the distance was still 20 two nautical miles.
At the same time, the radar operator reports the location of the new target to the command center, and asks them to contact the nearby navigation station to help inquire whether there is a registered ship at that location that will pass through here.
Very few ships will be navigable at the center of choice Miyako Strait, Sea Area, because to the north is the endless North Pacific Ocean. Since the patrol ship Hayakawa patrols at night, of course, it will Sea Area where choice ships are scarce, and specialize in catching those ships that are unwilling to take the normal course.
Navigation stations are all electronic offices. On a huge electronic chart, all the recorded trajectories of past ships are listed. Therefore, the other party gave a reply in less than ten seconds that no registered ships passed in the target area.
Well, it's another illegal navigable vessel.
While the radar operator set the target as a lock-on target, he thought to himself, judging by the location where the target appeared, the ship was driving in their direction. Then when they chased the illegal fishing boat, they could also catch that boat by turning around.
Lock the target, and the time until the radar gives detailed information is no more than one second.
The radar operator was ready to send a report to Captain, but at the next moment, he heard a piercing alarm from the radar console.
"Warning ~"
"Warning ~"
"An unknown ultra-low altitude flying object was found."
The radar operator looked at the warning message on the screen in confusion.
Several seconds ago, the unknown ship had just entered the radar detection range, and the two were two nautical miles away from 20.
Now the radar computer gives detailed data. The radar reflection characteristics of the unknown target cannot be used to identify whether it is a civilian or military ship, or even if it is not a ship at all.
Speed...
Speed 130 knots, 66m/s.
At this time, the operator panicked and recalled that the Hayakawa was the most advanced patrol ship installed by the Security Agency. The OPS-28D surface radar equipped with the ship is directly copied from the Atago-type frigate. It can not only search and identify surface ships, but also has the ability to identify ultra-low altitude aircraft, which is the sea-skimming anti-ship missile.
What can be an object that is traveling 66 meters per second at a speed of 130 knots, not a flying object?
Everyone in the command center stopped working and stared blankly at the radar operator.
"Damn it, what's the situation?" The Hayakawa patrol ship is a small ship, and electronic device controls system in one cabin. Captain Miyamoto Yoyama ran to the radar console, which kept warning, and looked ugly at anomaly. He really thought that the patrol ship had encountered an unknown enemy.
"This..." The radar operator was surprised. At this moment, he also saw the volume information of the flying object given by the radar. Although no match was found in the database, the computer vaguely gave a judgment that the object was more than 5,000 tons.
"Is this... 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.
"Huh?" The operator and Captain rubbed their eyes sharply. The original two tracking targets became one. The illegal fishing boat was still listed, but the edge target seemed to never appear.
After the alarm disappeared, in the command center, silence continued for a full half minute.
The radar has updated the data sixty times, and the target that the radar does not understand has never appeared.
The target cannot disappear instantly, and no ship can reach the speed of 130 knots.
aircraft is even more impossible, so large, unless it is an alien spacecraft.
"Captain, maybe... the radar is malfunctioning." The radar operator subconsciously tapped device~IndoMTL.com~I...Captain. If you are not worried, you can contact the headquarters and ask them to send a helicopter to search. "
Captain Miyamoto Yoyama frowned, and his heart was more inclined to radar false alarms. This situation is not very common, but it is never uncommon. Last year, the patrol ship in Kunashir Island made the biggest joke of radar false alarm.
The administrative area of Kunisaki Island is close to Kuril Island Chain, which is very close to Russia. During a patrol, the radar of the local patrol ship suddenly scanned an unknown circular target with a diameter of 800 meters, hovering at a very low altitude.
The radar operator was far less calm than his subordinate at the time. The guy quickly grabbed the emergency phone to report to the headquarters, saying that a UFO had come to Japan Sea Area.
The last two air-to-air fighters took off in an emergency. After the fuel was almost empty, Ghost Shadow did not find one.
If it weren't for someone inadvertently flipping through the on-board monitoring screen of that patrol ship at the end, this could become a mysterious mystery that could not be solved.
What is the result?
As a result, the storm reached Sixth Grade that day, and a piece of tin foil used for toasting in the patrol ship’s kitchen was somehow blown over the radar by the gale. The good electromagnetic reflectivity of the tin foil made the radar that could detect the volume misjudged. In the end, it was reported as a UFO by the uncool new graduates operator.
Captain Miyamoto Yoyama certainly couldn't make his own patrol ship appear this kind of absurd joke, but the radar detection time of tens of seconds still made him weigh in and grab the radio phone.
"This is the Hayakawa patrol ship. We found a case of the target anomaly during the patrol. We cannot judge the target. Please conduct a helicopter search after receiving the anomaly target position."
"The search range is 50 nautical miles." 8) For more exciting novels, welcome to visit Everyone's Reading Academy
