Chapter 231
Chapter 231, the surprise attack on Pearl Harbor, the nuclear explosion that shocked the world: 20 Mach speed, any defense system is useless! (Please subscribe!)
Chirp chirp… buzz buzz buzz!!!
The intercontinental missile quickly took off under the powerful thrust of the engine…
After the launch of the No. 5 missile, it can generally be divided into three stages, namely the propulsion acceleration stage, the mid-course stage (suborbital flight stage) and the re-entry stage. The first stage of the missile is about 60 seconds after it is launched.
At this time, its speed will reach Mach 1, which is equivalent to the speed of sound, that is, 1224 miles per hour.
Whoosh whoosh whoosh…
Soon, the missile’s flight altitude will reach more than 15,000 meters, and then the missile will do a second roll acceleration in the air.
Immediately, the second-stage booster engine ignites, and the missile deflector pops out at the same time.
Whoosh whoosh whoosh!
The second-stage booster engine separates about 120 seconds after the missile is launched.
Whoosh whoosh…
The missile’s speed is getting faster and faster. At an altitude of 9144 meters, it will reach a speed of three”nine-three-zero” Mach.
When it reaches an altitude of 30,000 meters, the missile will separate again. This time, the shell used to protect the warhead will be separated.
Clang clang clang!!!!
Shortly after this separation, the missile will separate again. This time, the missile’s own engine will be separated after ignition.
That is, the third-stage booster engine is ignited. About 180 seconds after the missile is launched, that is, when the missile reaches an altitude of more than 96,000 meters.
At this time, the missile’s acceleration is completed, and when it reaches the predetermined height, the fairing will separate from the entire missile.
From then on, the third-stage booster engine separates.
Chirp chirp… Whoosh whoosh… Whoosh whoosh…
From the time the engine is ignited, the entire flight time is about 5 minutes.
At this time, the missile flies upward in an angled manner under the huge thrust of the engine.
After acceleration, the missile’s flight speed can reach 4 miles per second. Arriving at the predetermined height, the engine separates (the third-stage booster engine separates).
This entire stage is the same principle as launching a satellite, and then comes the second stage (mid-course stage).
After the missile accelerates through the propulsion acceleration stage, the missile is about 150-400 kilometers above the ground. It begins to enter the suborbital orbit, and the flight speed is accelerated to the first cosmic speed. This stage will fly for about 25 minutes until it flies close to the target of attack.
This flight orbit is usually 35-300 kilometers away from the earth, which is generally the flight orbit of the missile, so it can also be called a ballistic orbit.
It is also called”suborbital flight”.
Suborbital flight is different from orbit. It cannot circle the earth once. It is elliptical in shape and will be affected by the earth’s gravity.
Therefore, after a period of flight, it will return to the ground, and the flight trajectory is parabolic.
Intercontinental missiles use this principle. According to the different attack distances and targets, after the missile is accelerated to the predetermined suborbital, the missile flies along the orbit and finally attacks the target on the ground.
At the same time, during this stage of flight, the reentry vehicle carrying a nuclear warhead or an intercontinental ballistic missile with multiple independently targetable reentry vehicles will release the warheads it carries, as well as various electronic countermeasures such as metal balloons, aluminum foil interference wires and full-size decoy warheads to deceive enemy radars.
Ensure that the reentry phase is not intercepted by the enemy’s air defense firepower network.
At the same time, the speed of the atmospheric flight phase is relatively stable, and the warhead carrier will adjust its attitude and flight heading.
Whoosh… buzz…
After the first and second stages of flight, the warhead part is very close to the target, which is also called”terminal flight”.
At the same time, the warhead crosses the Karman line at an altitude of 100 kilometers from one side of the universe.
The atmosphere at an altitude of 100 kilometers is called the Karman line.
At this time, the warhead part of the intercontinental missile is about 100 kilometers from the ground.
The flight time of this stage is about 2 minutes. The speed of the missile continues to increase under the propulsion of the engine. Before the engine is shut down, its terminal flight speed can reach 7 kilometers per second, which is about Mach 20.
According to human interception methods, it is still impossible to intercept aircraft with a speed of up to Mach 20. In addition, the target of the warhead is small and the reaction time is extremely short, so the possibility of successful interception is almost”0″.
Finally, the speed of the nuclear warhead during the re-entry phase will decrease under atmospheric resistance, from more than Mach 20 to more than ten Mach.
The flight of the entire intercontinental missile is a variable speed flight process, and the ballistic range is much longer than the range.
The average speed reaches Mach 15 (about 5100 meters/second).
If it flies 10,000 kilometers, it will take about 32 minutes, and if it flies 15,000 kilometers, it will take about 49 minutes.
It is worth noting that if the intercontinental missile carries a MIRV, after these two separations, the missile will be guided separately.
The multiple warheads carried by the missile will separate and continue to fly in the air.
At this time, the missile has completely passed through the atmosphere and reached space, and then the carrier aircraft of each warhead will release power to push the warhead into the atmosphere again.
Next, the missile will start the spin launcher to provide power to the warhead.
After the spin generator stabilizes, the missile can re-enter the atmosphere, move towards the target, and finally hit the target, causing serious damage.
However, the first intercontinental missile did not carry a multiple independently targetable reentry vehicle.
Whoosh… buzz…
The speed of the intercontinental missile is very fast. It only takes 40 minutes to reach a distance of more than 14,000 kilometers. It is very terrifying….
Since the first island chain defense had been cleared by the rabbit in advance, the No. 5 intercontinental missile quickly broke through the air above the foot basin chicken and arrived in the Pacific Ocean.
Whoosh…
After flying for about 30 minutes, the missile arrived in the airspace of Hawaii.
Buzz buzz… boom boom boom… whoosh…
The missile flew towards Pearl Harbor in a straight line. (To read the exciting novel, go to Feilu Novel Network!)
……
Hawaii.
Pearl Harbor stretches inland like a bird’s foot. At the southern end of the Waipio Peninsula between the West Bay and the Middle Bay, there is a milky white octagonal water tower.
The entire water tower is 55.8 meters high, with a red light on the top, which is a significant navigation sign for entering the port.
In addition, there is a Golden Eagle signal tower on the shore on the east side of the entrance corner of the port to assist navigation.
At this time.
Pacific Fleet Submarine Command. Admiral
Magill received a message from the White House:”The USS Parrot is about to arrive at Pearl Harbor?”
“General, that’s not right. Isn’t the Parrot a nuclear submarine? Logically speaking, it can reach the Rabbit East Sea without resupply.……”
The Nautilus is 98.7 meters long, has a displacement of 3,760 tons, an average speed of 20 knots, a maximum speed of 23 knots, and a maximum diving depth of 150-313 meters. Theoretically, it can sail underwater at maximum speed for 50 consecutive days and a range of 30,000 nautical miles without adding any fuel. Its endurance is an astonishing 70,000 nautical miles, which is enough for long-distance strategic patrols or mission execution.
There is no need to stop at Pearl Harbor at all.
“I don’t know!” Magill:”The Parrot nuclear submarine is our most advanced submarine. Could something have happened to it?”
“Immediately notify the dock to prepare to welcome the Parrot nuclear submarine… 2.2…”
As the supreme commander of the Pacific submarine, Magill knew that the Parrot nuclear submarine had a difficult mission.
No accidents could happen.[]
Submarine dock.
Under the gaze of the American navy, a 98.7-meter-long new nuclear submarine slowly emerged from the water.
Then, the submarine captain, Delis, came out:”Immediately replenish food, water, and daily necessities!”
This trip to the East China Sea will take 20 days or even a month, and hundreds of people will eat, drink, defecate and urinate in it.
Food, water and other daily necessities must be sufficient.
“Yes, Colonel Dalis……”
Then, the logistics personnel of Pearl Harbor began to replenish the”Parrot” submarine with various supplies.
At this time, they were unaware that an intercontinental missile was falling from the sky!!
No, to be precise, an intercontinental nuclear missile……
