At 4 o'clock in the morning, the ballistic recalculation was completed, and the missile was "flashed" by the data line, and a new control command program was input.
Then Dongfeng-3 entered a state of waiting quietly. After a few hours, it was confirmed that the launch plan would not be changed, and then fuel and oxidizer were injected into the first and second stages.
The fuel of Dongfeng-3 is unsymmetrical dimethylhydrazine, and the oxidant is dinitrogen tetroxide...a highly toxic and corrosive thing.Once the rocket or ballistic missile is injected, it must be launched. If it is not launched, even if the fuel and oxidant are drawn out, the body of the rocket/missile can no longer be used.
North of the island of Guinea, the fleet of ships kept maneuvering at a low speed on the sea surface.The 111 and 112 ships with high speed and fierce artillery are responsible for dealing with the US warships, and the 105 ships, 106 ships, supply ships, and Soviet support ships are "stepping out" in the sea area.
By the afternoon of February 2, the four ships that had stepped on the spot were ready to enter the position. On the Soviet support ship, two Ka-8 helicopters had repeatedly checked their machinery and were ready to take off at any time.
"Hey, you're just gathering together, are you playing mahjong?"
It's the talkative captain of the John King.
"Let me emphasize again that your US warships have been operating on the edge of the no-sail zone. This is a very unsafe behavior."
The talkative captain: "I just want to ask, what does it mean that your four warships occupy the four corners of a square with a side length of 4 kilometers? The center of them is the landing point of the missile?"
Kang Zhiqiang would not answer this question directly. "I solemnly remind you again: entering the no-navigation zone will be expelled by our warships; if entering the quadrilateral area, the consequences may be even more serious."
"Of course we're not going into that quadrilateral. Let's hope your missiles get into that."
The John King stopped chatting on the radio.The helicopter on the cruiser is also ready to take off. In addition, two US seaplanes flying from a distance have been circling outside the no-fly zone, just waiting for the Chinese missile to go astray.
When the U.S. Navy conducts sea launch tests of ballistic missiles, the sea area surrounded by warships is 10 kilometers by 10 kilometers, and the missiles launched are still medium-range Raytheon DM-18.It's a gambler's mentality for the Chinese to do this.
China shoots a missile that flies 5500 kilometers, and wants to fly into this rectangle?Then the circular probability deviation must be less than 2000 meters, in order to have more than 50% probability of falling in it.
……
Jiuquan.
"4, 3, 2, 1, launch!"
The fourth test-fired Dongfeng-3 ballistic missile in full state flew away from the launch pad, pierced through the sky and flew to the southeast.
The first three test launches of Dongfeng 3 were all high-trajectory flights, and they were all completely successful.The deviations of the landing points from the center of the three test launches were 330 meters, 890 meters and 260 meters respectively.
2月8日晚9时20分，一道亮线从编队西北方向出线，东风-3的弹头！
The bright line first appeared on the west side of the Palau Islands. The warhead entered within 100 kilometers, rubbed against the atmosphere, gradually became scorching hot, and finally glowed red.This is the stage of black barriers. If the warhead is equipped with a radio transceiver system, it will not be able to receive signals at this time.
On the sea, ships 105, 106, supply ships, and Soviet support ships were at the four corners of the square, and ships 111, 112, and Chongqing were in the outer circle, sailing in circles around the center, ready to keep the US warships out at any time.The three US warships did not squeeze in, but the seaplanes and "Sikorsky" helicopters were all in the sky.
The warhead continued to fall, decelerated, and decelerated a second time. When approaching the sea surface, the instrument compartment separated, opened the drogue parachute, and then slowly fell into the sea.The warhead's instrument bay ejected an orange-red airbag, and the white parachute dragged on the sea.Just 2 minutes later, two Ka-15s flew over the instrument cabin.
"According to visual inspection, the deviation from the center of the square is about 500 meters." The Ka-15 pilot reported, "It almost landed in the center area."
"Received. Thank you, thank you Soviet comrades for their helicopters and support ships." Zhang Xuesi said.
R7洲际导弹初期型的平均偏差是3000到8000米，美国“宇宙神”据说只有1500米。当然R7现在的最新型号可以打出1000米以内的平均偏差了，但东风-3从这四次试射的数据看，基本上还是现在地球上精度最高的远程/洲际弹道导弹。
Switch channels.Zhang Xuesi wanted to chat with Captain Tuberculosis of the United States.
"Captain Anderson, are you listening to the radio?"
……
"Thank you for your cooperation, you are all the best actors. We will have similar performance scenes in the future, and we must remember to come over then."
Chapter 10, "Comprehensive Interpretation of Laser Technology"
The no-flight zone designated by China for the launch vehicle test lasted 48 hours, but it actually took only 24 hours to complete the salvage and aftermath work.
At noon on February 2th, the high-power radio station used by the Chongqing ship reposted the announcement issued by the Chinese government that the "no-sail zone will end early" to ensure that fishermen and shipping companies in Indonesia, Papua New Guinea, and the Philippines could receive it, and then brought it to China. The team headed north.
The People's Navy's first voyage to the deep sea has lasted for 45 days, and it will take several days to sail from New Guinea to Shanghai.
The 7 Chinese warships flew away, and the warships of the U.S. Navy were still wandering around near the missile landing point.
The landing area of Dongfeng-3 is a deep sea with a water depth of 1500 to 1700 meters. The counterweight of the warhead sank to the bottom, and the floating instrument cabin and parachute were picked up by the helicopter. Data from two radar stations, analyzing the flight trajectories of Chinese ballistic missiles.This may reverse the performance of the missile.
"When the Laoag radar station in the Philippines caught the missile for the first time, it was already in the middle of the flight, and the two-stage booster rockets had been shut down and fell off. The flying object in space was small and fast..."
The "United Nations Command" in Tokyo, the U.S. military intelligence department in the Western Pacific, and the CIA's Far East Intelligence Agency are collecting data from various departments.
"Judging from the speed of the warhead in the middle of the flight, the maximum range of this Chinese missile is 5500 to 5700 kilometers. The missile does not use high-throwing ballistics, but this is normal. China should have carried out high-throwing on their own territory more than once. Ballistic test-firing, and a reliable success rate was achieved before the full-range ballistic test-firing at sea."
"The 5500-kilometer range can enclose all our military bases in the Western Pacific, and cover Alaska in Northeast China, but it cannot hit the continental United States. So..."
"So there must be a longer-range missile project in China." Richard Younger of the CIA's Far East Intelligence Agency said, "I noticed the conversation between the Chinese formation commander and Captain Anderson."
"The Seventh Fleet will be very busy in the future, just like the Fourth Fleet is in the Arctic Ocean and the North Atlantic." Frederick Kiwitt commented.
They monitored Soviet warships, blocked submarines at the exit of the Arctic Ocean, competed with Soviet long-range aircraft, and looked up from time to time to see if the Soviet Union launched ballistic missiles.The current Fourth Fleet (Atlantic Fleet) is not only the largest, but also the busiest.

"In order to promote the research and utilization of space by human civilization, and promote the pace of mankind's understanding of the universe and marching into the universe, the Central Committee of the Soviet Union decided to launch the human spaceflight program."
"Project Vostok aims to send humans into space, in orbit around the Earth, and return them safely to Earth."
"Humans have lived on the earth for millions of years since their birth. 60 years ago, human beings left the land and sea for the first time and entered the sky. Today, human beings will go one step further and step into space."
"In April of this year, the Soviet Union will launch the first test spacecraft of the 'Oriental Project'."
"Project Vostok will send astronauts into space by December 1961 at the latest."
In January and February, China was unrivaled in the field of coercion.With the current posture, the Soviet Union intends to start in April and contract the laurels of the world's kings of pretentiousness for the rest of 1.
"Excuse me, after you send people into space, how do you ensure that humans can breathe in space?"
The reporters in the audience raised their hands to ask the first question.
"The spacecraft that the astronauts take will be completely sealed, filled with air, the composition of the air is the same as that of the atmosphere on the surface, and it will have an air filtration and recirculation system to continuously replenish the oxygen of the spacecraft."
Mikhail Menshikov, the Soviet ambassador to the United States, patiently answered the question of the junior high school graduate, "So astronauts can breathe freely in the spacecraft. In addition, the spacecraft also has heat dissipation and heating, radiation protection, communication and power. system, astronauts can manually control the spacecraft to fly in orbit or return to Earth."
Paramount-ABC TV reporter: "Did the Soviet spaceship have a military purpose?"
Menshikov: "No."
"It can appear in the sky above any place below 60 degrees north and south latitude on the earth. Just throwing a bomb on the ground will cause huge damage." The ABC reporter continued to argue.
Menshikov: "We don't want to throw."

“苏联这个东方号火箭，其实和月球号、8K72、8K71、R7弹道导弹一脉相承下来的，连外形都差不多。”
Tang Hua was already on the return train when he heard the news that the Soviet Union had thrown out its own manned spaceflight program.
