The ABM-1 Galosh(Soviet designation A-350 GRAU 5V61) was a Soviet, nuclear armed surface-to-air anti-ballistic missile. The Galosh (NATO reporting name, formerly SH-01) was a component of the A-35 anti-ballistic missile system. Its primary mission was to destroy U.S. Minuteman and Titan intercontinental ballistic missiles targeting Moscow.
The ABM-1 was introduced during the 1960s with mechanically steered semi-active radar guidance. It contained a high-yield nuclear warhead, comparable to the U.S. Nike Zeus.
The ABM-1B (Soviet designation A-350R) was introduced with the advanced A-35M missile system and became operational during 1978. This system was tested at the Sary Shagan Launch Facility with five test flights during 1971, 1976, and 1977, with two more tests during 1993 and 1999.
The next generation of missiles, introduced with the A-135 ABM System, were the ABM-3 Gazelle (1970s), and ABM-4 Gorgon (1980s).
The ABM-1 Galosh was a three-stage solid-fueled design with a range of over 300 kilometers. The ABM-1B was improved with a restartable liquid-fueled third stage. This gave a much improved post-launch and re-targeting capabilities. The Galosh are launched from above-ground launchers.
The missile design was done by MKB Fakel's Chief Designer Petr Grushin.
The system had multiple radars during the different phases including the Pill Box and Hen House early warning systems, and the Dog House and Cat House target acquisition systems. The A-35 with radar was designed by Chief Designer K. B. Kisunko.
The idea for this system was to protect Moscow from nuclear attack by the United States. The Russian government began studies during 1958 with preliminary designs from General Designer K. B. Kisunko. Further designs and development were moved to TsNPO Vympel. Radar systems were tested with Duna-3 single direction search radar and the Dunay-3U omni-direction 360-degree search radar, designed by V. P. Sosulnikov and A. N. Musatov, respectively. A more advanced system of radars were included, the Don-2N System; consisting of the 6000 km long-range early warning radars, (NATO code names Pill Box and Hen House ), and the 2800 km short-range target acquisition radars (NATO codenames Dog House and Cat House ).
The A-350 developed through a period of growth and modifications. Configurations included an improved A-350Zh with tests during 1973. Eventually, the design changed again with radiation-hardened cases and became the A-350R for Phase 2 deployment in 1974.
The construction of the ABM-1 system began during 1962 with 16 primary sites including command post, radar installations and firing complexes for 8–16 missile launchers. Some of the existing sites of the old SA-1 Guild were modified. Some known locations are: Naro-Fominsk, Olenegorsk, Skrunda, Angarsk, Nikolaeyev, and Sary Shagan.
One of the Dunay radar (NATO Code : Dog House) phased array radar systems was located at Naro-Fominsk. This system is comparable to the US's PAVE PAWS radars of the Sentinel and Safeguard ABM programs.
The construction plan changed a number of times, varying the locations, sectors or quadrants, and number of launchers. The system finalized at 8 sites with total of 64 launchers, with 4 major radar centers completed.
With on-going advancements in the ABM system, radars, missile and warheads, the evolution of the ABM-1 Galosh became the ABM-1B Galosh. The "M" for modernization, was brought on through the advanced developments at 10 different Russian institutes. One primary upgrade was in the Dunay-3U radar systems enhanced with a dedicated sector search functionality. Along with other upgrades, actual air tests were performed with different configurations between 1976 and 1977. Phase 3 of the Galosh went on-line in 1978.
An anti-ballistic missile (ABM) is a surface-to-air missile designed to counter ballistic missiles. Ballistic missiles are used to deliver nuclear, chemical, biological, or conventional warheads in a ballistic flight trajectory. The term "anti-ballistic missile" is a generic term conveying a system designed to intercept and destroy any type of ballistic threat; however, it is commonly used for systems specifically designed to counter intercontinental ballistic missiles (ICBMs).
An intercontinental ballistic missile (ICBM) is a missile with a minimum range of 5,500 kilometres (3,400 mi) primarily designed for nuclear weapons delivery. Similarly, conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicles (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. Russia, United States, China, France, India, United Kingdom, and North Korea are the only countries that have operational ICBMs.
Chevaline was a system to improve the penetrability of the warheads used by the British Polaris nuclear weapons system. Devised as an answer to the improved Soviet anti-ballistic missile defences around Moscow, the system increased the probability that at least one warhead would penetrate Moscow's anti-ballistic missile (ABM) defences, something which the Royal Navy's earlier UGM-27 Polaris re-entry vehicles (RV)s were thought to be unlikely to do.
National missile defense (NMD) is a generic term for a type of missile defense intended to shield an entire country against incoming missiles, such as intercontinental ballistic missile (ICBMs) or other ballistic missiles.
The Fractional Orbital Bombardment System (FOBS) was a nuclear-weapons delivery system developed in the 1960s by the Soviet Union. One of the first Soviet efforts to use space to deliver weapons, FOBS envisioned launching nuclear warheads into low Earth orbit before bringing them down on their targets.
Missile defense is a system, weapon, or technology involved in the detection, tracking, interception, and destruction of attacking missiles. Originally conceived as a defense against nuclear-armed intercontinental ballistic missiles (ICBMs), its application has broadened to include shorter-ranged non-nuclear tactical and theater missiles.
Sary Shagan is an anti-ballistic missile testing range located in Kazakhstan.
The Sprint was a two-stage, solid-fuel anti-ballistic missile (ABM), armed with a W66 enhanced-radiation thermonuclear warhead used by the United States Army. It was designed to intercept incoming reentry vehicles (RV) after they had descended below an altitude of about 60 kilometres, where the thickening air stripped away any decoys or radar reflectors and exposed the RV to observation by radar. As the RV would be travelling at about 5 miles (8.0 km) per second, Sprint had to have phenomenal performance to achieve an interception in the few seconds before the RV reached its target.
Terra-3 was a Soviet laser testing centre, located on the Sary Shagan anti-ballistic missile (ABM) testing range in the Karaganda Region of Kazakhstan. It was originally built to test missile defense concepts, but these attempts were dropped after the Anti-Ballistic Missile Treaty was signed. The site later hosted two modest devices used primarily for experiments in space tracking. Several other laser test sites were also active during this period. During the 1980s, officials within the United States Department of Defense (DoD) suggested it was the site of a prototypical anti-satellite weapon system. The site was abandoned and is now partially disassembled.
The A-135 is a Russian anti-ballistic missile system deployed around Moscow to intercept incoming warheads targeting the city or its surrounding areas. The system was designed in the Soviet Union and entered service in 1995. It is a successor to the previous A-35, and complies with the 1972 Anti-Ballistic Missile Treaty.
The A-35 anti-ballistic missile system was a 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 since the 1960s and in operation from 1971 until the 1990s, it featured the nuclear-tipped A350 exoatmospheric interceptor missile. The A-35 was supported by the two Dunay radars and the Soviet early warning system. It was followed by the A-135 in the early 1990s.
Dunay radar was a system of two Soviet radars used to detect American ballistic missiles fired at Moscow. They were part of the A-35 anti-ballistic missile system. One sector of one of the radars, the Dunay-3U is still operational and is run by the Russian Aerospace Defence Forces as part of the Main Control Centre of Outer Space.
The 53T6 is a Russian anti-ballistic missile. Designed in 1978 and in service since 1995, it is a component of the A-135 anti-ballistic missile system.
The Daryal-type radar is a Soviet bistatic early-warning radar. It consists of two separate large active phased-array antennas separated by around 500 metres (1,640 ft) to 1.5 kilometres (4,921 ft). The transmitter array is 30 m × 40 m and the receiver is 80 m × 80 m in size. The system is a VHF system operating at a wavelength of 1.5 to 2 meters. Its initial transmit capacity was 50 MW with a target capacity of 350 MW.
Dnestr radar and Dnepr radar, both known by the NATO reporting name Hen House are the first generation of Soviet space surveillance and early warning radars. Six radars of this type were built around the periphery of the Soviet Union starting in the 1960s to provide ballistic missile warnings for attacks from different directions. They were the primary Soviet early warning radars for much of the later Cold War. In common with other Soviet and Russian early warning radars they are named after rivers, the Dnestr and the Dnepr.
The Don-2N radar is a large missile defense and early warning passive electronically scanned array radar outside Moscow, and a key part of the Russian A-135 anti-ballistic missile system designed for the defense of the capital against ballistic missiles. Located near Sofrino in Pushkinsky District of Moscow Oblast, it is a quadrangular frustum 33 metres (108 ft) tall with sides 130 metres (427 ft) long at the bottom, and 90 metres (295 ft) long at the top. Each of its four faces has an 18 metres (59 ft) diameter Ultra high frequency band radar giving 360 degree coverage. The system is run by an Elbrus-2 supercomputer.
Balkhash Radar Station is the site of two generations of Soviet and Russian early warning radars. It is located on the west coast of Lake Balkhash near Sary Shagan test site in Kazakhstan. Although it was used for monitoring satellites in low Earth orbit it was mainly a key part of the Russian system of warning against missile attack. It provided coverage of western and central China, India, Pakistan and submarine missile launches in the Bay of Bengal. There have been six radars at this site, the last one was removed from service in 2020, and it was run by the Russian Aerospace Defence Forces.
Missile defense systems are a type of missile defense intended to shield a country against incoming missiles, such as intercontinental ballistic missile (ICBMs) or other ballistic missiles. The United States, Russia, India, France, Israel, Italy, United Kingdom and China have all developed missile defense systems.
The 5N65 radar was a Soviet military phased array radar initially designed for the S-225 anti-ballistic missile system which was never commissioned. The radar was later installed near the Kura Test Range in Kamchatka in the Russian Far East as a part of 5K17 tracking and measuring system and was demolished in 2006.
The RS-26 Rubezh SS-X-31 or SS-X-29B, is a Russian solid-fueled intercontinental ballistic missile, equipped with a thermonuclear MIRV or MaRV payload. The missile is also intended to be capable of carrying the Avangard hypersonic glide vehicle. The RS-26 is based on RS-24 Yars, and constitutes a shorter version of the RS-24 with one fewer stages. The development process of the RS-26 has been largely comparable to that of the SS-20 Saber, a shortened derivative of the SS-16 Sinner. Deployment of the RS-26 is speculated to have a similar strategic impact as the SS-20.
