US-KMO
US-KMO (), an abbreviation for Upravlyaemy Sputnik - Kontinenty Morya Okeany () meaning ''Controllable Satellite - Continents, Oceans, Seas'' is a series of Russian, previously Soviet, satellites which are used to identify ballistic missile launches. They provide early warning of missile attack and give information for the Moscow A-135 anti-ballistic missile system. They were run by the Russian Space Forces and it was succeeded by the Aerospace Defence Forces. These satellites are part of the Oko programme and are in geosynchronous orbit 35,750 km above the Earth's equator. This means that they are always in the same place with the same field of view. Western locations give Russia coverage of missile launches in the United States whereas more eastern ones give coverage of China and the Middle East. They complement ground-based early warning radars and the US-K satellites which are in molniya orbits. The first prototype satellite was launched on 8 October 1975, atop a Pro ...

US-K
Upravlyaemy Sputnik Kontinentalny ( meaning ''Continental Controllable Satellite'') or US-K () is a series of Russian, previously Soviet Union, Soviet, satellites used to detect missile launches as part of the Oko system. It consists of a constellation of satellites, usually in molniya orbits, designated under the Kosmos (satellite), Kosmos system. The satellites are built by the company NPO Lavochkin and are launched on Molniya-M rockets. Oko can be directly translated as the Russian word for eye. As of June 2014, only two of the eight satellites in orbit were still functional, rendering the system inoperable. History US-K are the first generation of Oko satellites, the first of which was launched in 1972. The vast majority of the satellites launched (86 out of 100 as of March 2012 ) have been US-K satellites in molniya orbits. Seven first generation satellites were launched into geosynchronous orbits, called US-KS, starting in 1975. A decree of 3 September 1979 led to the crea ...

1983 Soviet Nuclear False Alarm Incident
On 26 September 1983, during the Cold War, the Soviet nuclear early warning system Oko reported the launch of one intercontinental ballistic missile with four more missiles behind it, from the United States. These missile attack warnings were suspected to be false alarms by Stanislav Petrov, an engineer of the Soviet Air Defence Forces on duty at the command center of the early-warning system. He decided to wait for corroborating evidence—of which none arrived—rather than immediately relaying the warning up the chain of command. This decision is seen as having prevented a retaliatory nuclear strike against the United States and its NATO allies, which would likely have resulted in a full-scale nuclear war. Investigation of the satellite warning system later determined that the system had indeed malfunctioned. Background The incident occurred at a time of severely strained relations between the United States and the Soviet Union. Responding to the Soviet Union's ...

EKS (satellite)
EKS ( meaning Integrated Cosmos System ) Kupol ( meaning Dome) is a developing programme of Russian early warning satellites as a replacement for the US-KMO and US-K satellites of the Oko programme. The satellites are designed to identify any possible future ballistic missile launches, from outer space, and complement early warning radars such as the Voronezh. This gives advance notice of a nuclear attack and would provide information to the A-135 missile defence system which protects Moscow, as well as other Russian missile defense and counterattack resources. Six satellites are planned to be initially orbited. The first of these was launched on 17 November 2015 and , all six of them are in service. Background EKS has been designated to detect and track ballistic missiles launched towards Russia or its allies. The systems have been designed as a replacement for the current system of early warning satellites called Oko, which had its first launch in 1972 and was described in ...

LGM-30 Minuteman
The LGM-30 Minuteman is an American land-based intercontinental ballistic missile (ICBM) in service with the Air Force Global Strike Command. , the LGM-30G (Version 3) is the only land-based ICBM in service in the United States and represents the land leg of the U.S. nuclear triad, along with the Trident II submarine-launched ballistic missile (SLBM) and nuclear weapons carried by long-range strategic bombers. Development of the Minuteman began in the mid-1950s when basic research indicated that a solid-fuel rocket motor could stand ready to launch for long periods of time, in contrast to liquid-fueled rockets that required fueling before launch and so might be destroyed in a surprise attack. The missile was named for the colonial minutemen of the American Revolutionary War, who could be ready to fight on short notice. The Minuteman entered service in 1962 as a deterrence weapon that could hit Soviet cities with a second strike and countervalue counterattack if the U.S. wa ...

A-35 Anti-ballistic Missile System
The A-35 anti-ballistic missile system was a USSR, Soviet military anti-ballistic missile (ABM) system deployed around Moscow to intercept enemy ballistic missiles targeting the city or its surrounding areas. The A-35 was the only Soviet ABM system allowed under the 1972 Anti-Ballistic Missile Treaty. In development as of the 1960s and in operation from June 1972 until the 1990s, it featured the nuclear-armed ABM-1 Galosh, A350 Exosphere, exoatmospheric interceptor missile. The A-35 was supported by two Dunay radars (NATO reporting name, NATO reporting names: Cat House and Dog House) and the Soviet early warning system. It was followed by the A-135 anti-ballistic missile system, A-135 in the early 1990s. System A The first Soviet anti-ballistic missile system was System A, which began development at Sary Shagan, Sary Shagan's Test Range A in July 1956, followed by testing starting in 1959. System A used the Fakel V-1000, V-1000 missile to intercept enemy missiles. First launch of t ...

S-25 Berkut
The S-25, initially designated as Berkut (; "Berkut" means golden eagle in English) is a surface-to-air guided missile, the first operational SAM system in the Soviet Union. In the early 1950s it was tested at Kapustin Yar. It was deployed in several rings around Moscow starting in 1955 and became combat ready in June 1956. The system failed, however, to detect, track, and intercept the only overflight of the Soviet capital Moscow by a U-2 reconnaissance plane on July 5, 1956. It was used only defensively at Moscow; the more mobile S-75 (SA-2 Guideline) would be used in almost all other locations. Several improvements were introduced over its long service lifetime, and the system was finally replaced by the S-300P in 1982. Its NATO reporting name is SA-1 ''Guild''. S-25 is short for ''Systema 25'', referring to the entire system of missiles, radars, and launchers. Portions of the system include the V-300 missile, R-113 and B-200 radars, and A-11/A-12 antennas for the B-200. Ba ...

Kosmos 2469
Kosmos 2469 ( meaning ''Cosmos 2469'') was a Russian US-K missile early warning satellite which was launched in 2010 as part of the Russian Space Forces' Oko programme. The satellite was designed to identify missile launches using optical telescopes and infrared sensors. Kosmos 2469 was launched from Site 16/2 at Plesetsk Cosmodrome in Russia. A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 17:01 UTC on 30 September 2010. The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 2010-049A. The United States Space Command assigned it the Satellite Catalog Number 37170. It was the last launch of a US-K satellite and the last launch of a Molniya-M rocket. On 15 October 2022, Kosmos 2469 re-entered the atmosphere. See also *List of Kosmos satellites (2251–2500) The designation '' Kosmos'' ( meaning ''Cosmos'') is a generic ...
