The 4th Air and Air Defence Forces Command was a formation of the Russian Air Force.
 It was formed on 1 December 2009 from the amalgamation of the 4th Air and Air Defence Forces Army and 5th Air and Air Defence Forces Army.
 The command's headquarters was in Rostov-on-Don, and it was responsible for the air defence of the North Caucasus Military District and the Volga-Urals Military District.
 The command became the 4th Air and Air Defence Forces Army again on 1 August 2015.
On 26 September 1983, the nuclear early warning system of the Soviet Union reported the launch of multiple USAF Minuteman intercontinental ballistic missiles from bases in the United States.
 These missile attack warnings were correctly identified as a false alarm by Stanislav Yevgrafovich Petrov, an officer of the Soviet Air Defence Forces.
 This decision is seen as having prevented a retaliatory nuclear attack based on erroneous data on the United States and its NATO allies, which would have probably resulted in immediate escalation of the cold-war stalemate to a full-scale nuclear war.
 Investigation of the satellite warning system later confirmed that the system had malfunctioned.
On 20 April 1978, Soviet air defense shot down Korean Air Lines Flight 902 (KAL 902) near Murmansk, Soviet Union, after the civilian aircraft violated Soviet airspace and failed to respond to Soviet ground control and interceptors.
 Soviet Air Defence Forces initially identified it as part of the US air reconnaissance force, which carried out thousands of flights along Soviet borders annually at the time.
 Captain Alexander Bosov, pilot of the Sukhoi Su-15 that brought down Flight 902, saw Asian logogram characters on the tail of the Korean aircraft, and reported this to the ground control.
 Despite this, Vladimir Tsarkov, commander of the 21st Soviet Air Defence Corps, ordered Bosov to take down the plane, as the plane failed to respond to repeated orders to land, and was approaching the Soviet border with Finland.
 The Su-15 opened fire, forcing the plane to descend, and killing two of the 109 passengers and crew members aboard Flight 902.
 The plane made an emergency landing on the frozen Korpiyarvi lake (not to be confused with the Korpijärvi lake) near the Finnish border.
The Man Who Saved the World is a 2014 feature-length Danish documentary film by film maker Peter Anthony about Stanislav Petrov, a former lieutenant colonel of the Soviet Air Defence Forces and his role in preventing the 1983 Soviet nuclear false alarm incident from leading to nuclear holocaust.
The 8th Red Banner Air Defence Corps (Military Unit Number 54912) was a corps of the Soviet Air Defence Forces, active from 1960 to 2001.
 It was part of the 11th Air Defence Army, and subsequently the 11th Army of Air Forces and Air Defence Forces.
The Soviet Air Forces (Russian: Военно-воздушные силы , "Voyenno-Vozdushnye Sily" (VVS), literally "Military Air Forces") was the official designation of one of the air forces of the Soviet Union.
 The other was the Soviet Air Defence Forces.
 The Air Forces were formed from components of the Imperial Russian Air Service in 1917, and faced their greatest test during World War II.
 The groups were also involved in the Korean War, and dissolved along with the Soviet Union itself in 1991–92.
 Former Soviet Air Forces' assets were subsequently divided into several air forces of former Soviet republics, including the new Russian Air Force.
 "March of the Pilots" was its anthem.
The Order of Lenin Moscow Air Defence District was a formation of the Soviet Air Defence Forces and the Russian Air Defence Forces, which existed from 1954 to 1998, to fulfill the tasks of anti-aircraft Defense of administrative and economic facilities.
 The district administration was in Moscow.
Stanislav Yevgrafovich Petrov (Russian: Станисла́в Евгра́фович Петро́в ; 7 September 1939 – 19 May 2017) was a lieutenant colonel of the Soviet Air Defence Forces who became known as "the man who single-handedly saved the world from nuclear war" for his role in the 1983 Soviet nuclear false alarm incident.
The 21st Air Defence Corps was a corps of the Soviet Air Defence Forces and later the Russian Air Force.
 The corps was headquartered at Severomorsk and was part of the 10th Air Defence Army from 1960 to 1994.
 It was formed as the Northern Air Defence Corps in 1957 and was assigned a number three years later.
 It became a brigade in 2009 and was converted into a division in 2014.
The Soviet Air Defence Forces (Russian: войска ПВО , voyska protivovozdushnoy oborony, voyska PVO, V-PVO, lit.
 "Anti-Air Defence Troops"; and formerly protivovozdushnaya oborona strany, PVO strany, lit.
 "Anti-Air Defence of the Nation") was the air defence branch of the Soviet Armed Forces.
 It continued being a service branch of the Russian Armed Forces from 1991 to 1998.
 Unlike Western air defence forces, V-PVO was a branch of the military unto itself, separate from the Soviet Air Force (VVS) and Air Defence Troops of Ground Forces.
 During the Soviet period it was generally ranked third in importance of the Soviet services, behind the Strategic Rocket Forces and the Ground Forces.
