Lin Liguo (; 23 December 1945 – 13 September 1971) was the son of Chinese marshal Lin Biao. He was the alleged leader of Project 571, a coup plot against Chinese Communist Party chairman Mao Zedong.

Biography

Lin was born on December 23, 1945. He graduated from the elite Beijing No. 4 High School and later entered the Faculty of Physics at Peking University. He later became member of the Chinese Communist Party.

Following the start of Cultural Revolution, he dropped out of the university and joined the People's Liberation Army Air Force in 1967. Lin was promoted to the deputy director of the Office of the Air Force Command in 1969, by the commander of PLAAF Wu Faxian. This was an important position, as all crucial documents were required to pass through Lin's hands.

According to Wu Faxian's testimony in the 1980 trial:

Mao Zedong's government claims that in 1970, under his father Lin Biao's direction, Lin Liguo made a plan known as "Project 571" to assassinate Mao Zedong in Shanghai, but Mao was alerted to it and left Shanghai one day ahead of schedule and changed return route back to Beijing. In February 1971, Lin Liguo took Yu Xinye, the deputy director of the Political Department of the PLAAF to Hangzhou; then he called another deputy director Zhou Yuchi from Beijing to Shanghai, and met them in Shanghai from 20 to 24 March.

The Lin family, including Lin Biao, Ye Qun, and Lin Liguo, attempted to flee after the coup failed. On 13 September 1971, they fled in a PLAAF Hawker Siddeley Trident, from Qinhuangdao Shanhaiguan Airport.

Party documents later released state:

"the plane was making for the Soviet Union but was inadequately fueled for such a trip; it also had on board neither navigator nor radio operator. It crashed in Mongolia on September 13, 1971, burning to death all on board."

However, according to the historian J. D. Spence, "this story is essentially beyond verification, since the photographs later released by the Chinese authorities are of dubious authenticity and details on Lin Biao’s exact plans and on the other plotters are blurred" The government narrative also does not sufficiently explain how and why Lin Biao's plane crashed. Skeptics have claimed that Lin's decision to flee to the Soviet Union was illogical, on the grounds that the United States or Taiwan would have been safer destinations.

From November 1980 to January 1981, the trial of the members belonging to the "counter-revolutionary" group of Lin Biao and Gang of Four was held in Beijing. In particular, five high-ranking military personnel, including Wu Faxian, appeared before the court, where they testified that Lin Liguo was actively involved in Project 571. It is also still unclear whether Lin Biao himself planned a coup, or whether Lin Liguo and Ye Qun had such plans and did not inform Lin Biao about them.
