Stanislav Yevgrafovich Petrov (Russian: Станисла́в Евгра́фович Петро́в; born 1939 in Vladivostok) is a retired lieutenant colonel of the Soviet Air Defence Forces.

Stanislav Petrov was born on September 7, 1939, and lived in Vladivostok. In 1972 he graduated from the Higher School of Radio Engineering by the Kiev Air Force and arrived to provide services to the Serpukhov-15 unit in the Mosca region. In 1983 the colonel lieutenant was responsible for the proper functioning of the satellite that provided part of the missile attack alert system. In Serpukhov-15 he has worked as an analyst chief.


On September 26, 1983, just three weeks after the Soviet military had shot down Korean Air Lines Flight 007, Petrov was the duty officer at the command center for the Oko nuclear early-warning system when the system reported that a missile, followed by another one and then up to five more, were being launched from the United States.

Petrov judged the report to be a false alarm, and his decision is credited with having prevented an erroneous retaliatory nuclear attack on the United States and its NATO allies that could have resulted in large-scale nuclear war. Investigation later confirmed that the satellite warning system had indeed malfunctioned.

Control structure Oko system

The system has two dedicated control centres. The western centre is at Serpukhov-15 (Russian: Серпухов-15) near Kurilovo outside Moscow (55°04′06″N 37°02′29″E) and the eastern centre is at Pivan-1 (Russian: Пивань-1)  (50°20′57″N 137°11′22″E) in the Russian Far East. The centre at Serpukhov-15 burned down in 2001  which caused the loss of contact with currently orbiting satellites.

The Incident

According to the Permanent Mission of the Russian Federation to the UN – on 19 January 2006, over 22 years after the incident – nuclear retaliation requires that multiple sources confirm an attack. In any case, the incident exposed a serious flaw in the Soviet early warning system. Petrov asserts that he was neither rewarded nor punished for his actions.



Had Petrov reported incoming American missiles, his superiors might have launched an assault against the United States, precipitating a corresponding nuclear response from the United States. Petrov declared the system’s indication a false alarm. Later, it was apparent that he was right: no missiles were approaching and the computer detection system was malfunctioning. It was subsequently determined that the false alarm had been created by a rare alignment of sunlight on high-altitude clouds and the satellites’ Molniya orbits, an error later corrected by cross-referencing a geostationary satellite.

Petrov later indicated that the influences on his decision included: that he was informed a U.S. strike would be all-out, so five missiles seemed an illogical start; that the launch detection system was new and, in his view, not yet wholly trustworthy; and that ground radar failed to pick up corroborative evidence, even after minutes of delay.

However, in a 2013 interview, Petrov said at the time he was never sure that the alarm was erroneous. He felt that his civilian training helped him make the right decision. His colleagues were all professional soldiers with purely military training and, following instructions, would have reported a missile strike if they had been on his shift.

Petrov underwent intense questioning by his superiors about his judgment. Initially, he was praised for his decision.

General Yury Votintsev, then commander of the Soviet Air Defense’s Missile Defense Units, who was the first to hear Petrov’s report of the incident (and the first to reveal it to the public in the 1990s), states that Petrov’s “correct actions” were “duly noted.” Petrov himself states he was initially praised by Votintsev and promised a reward, but recalls that he was also reprimanded for improper filing of paperwork under the pretext that he had not described the incident in the war diary.

He received no reward. According to Petrov, this was because the incident and other bugs found in the missile detection system embarrassed his superiors and the influential scientists who were responsible for it, so that if he had been officially rewarded, they would have had to be punished.

He was reassigned to a less sensitive post, took early retirement (although he emphasizes that he was not “forced out” of the army, as it is sometimes claimed by Western sources), and suffered a nervous breakdown.

In a later interview, Petrov stated that the famous red button has never worked, as military psychologists did not want to put the decision about a war into the hands of one single person.

The incident became known publicly in the 1990s upon the publication of Votintsev’s memoirs. Widespread media reports since then have increased public awareness of Petrov’s actions.

There is some confusion as to precisely what Petrov’s military role was in this incident. Petrov, as an individual, was not in a position where he could single-handedly have launched any of the Soviet missile arsenal. His sole duty was to monitor satellite surveillance equipment and report missile attack warnings up the chain of command; top Soviet leadership would have decided whether to launch a retaliatory attack against the West. But Petrov’s role was crucial in providing information to make that decision. According to Bruce Blair, a Cold War nuclear strategies expert and nuclear disarmament advocate, formerly with the Center for Defense Information, “The top leadership, given only a couple of minutes to decide, told that an attack had been launched, would make a decision to retaliate.”

Petrov later said “I had obviously never imagined that I would ever face that situation. It was the first and, as far as I know, also the last time that such a thing had happened, except for simulated practice scenarios.”

Awards and commendations

On May 21, 2004, the San Francisco-based Association of World Citizens gave Petrov its World Citizen Award along with a trophy and $1000 “in recognition of the part he played in averting a catastrophe.”

In January 2006, Petrov traveled to the United States where he was honored in a meeting at the United Nations in New York City. There the Association of World Citizens presented Petrov with a second special World Citizen Award.

The next day, Petrov met American journalist Walter Cronkite at his CBS office in New York City.

That interview, in addition to other highlights of Petrov’s trip to the United States, were filmed for The Man Who Saved the World, a narrative feature and documentary film, directed by Danish director Peter Anthony, which premiered in October 2014 at the Woodstock Film Festival in Woodstock, New York, winning “Honorable Mention: Audience Award Winner for Best Narrative Feature” and “Honorable Mention: James Lyons Award for Best Editing of a Narrative Feature.”

For his actions in averting a potential nuclear war in 1983, Petrov was awarded the Dresden Preis 2013 (Dresden Prize) in Dresden, Germany, on February 17, 2013. The award included €25,000 ($32,000; £21,000). On February 24, 2012, he was honored with the 2011 German Media Award, presented to him at a ceremony in Baden-Baden, Germany.

On the same day that Petrov was honored at the United Nations in New York City, the Permanent Mission of the Russian Federation to the United Nations issued a press release contending that a single person could not have started or prevented a nuclear war, stating in part: “Under no circumstances a decision to use nuclear weapons could be made or even considered in the Soviet Union (Russia) or in the United States on the basis of data from a single source or a system. For this to happen, a confirmation is necessary from several systems: ground-based radars, early warning satellites, intelligence reports, etc.”

But Bruce Blair has said that at that time the U.S.–Soviet relationship “had deteriorated to the point where the Soviet Union as a system—not just the Kremlin, not just Andropov, not just the KGB—but as a system, was geared to expect an attack and to retaliate very quickly to it. It was on hair-trigger alert. It was very nervous and prone to mistakes and accidents. … The false alarm that happened on Petrov’s watch could not have come at a more dangerous, intense phase in U.S.–Soviet relations.”

At that time, according to Oleg D. Kalugin, a former KGB chief of foreign counterintelligence, “The danger was in the Soviet leadership thinking, ‘The Americans may attack, so we better attack first.'”


Petrov has said he does not know that he should regard himself as a hero for what he did that day.

In an interview for the film The Man Who Saved the World, Petrov says, “All that happened didn’t matter to me — it was my job. I was simply doing my job, and I was the right person at the right time, that’s all. My late wife for 10 years knew nothing about it. ‘So what did you do?’ she asked me. ‘Nothing. I did nothing.'”
