A railcar-launched ICBM is an intercontinental ballistic missile that can be launched from a train. The first operational example, and the best-known, is the Soviet RT-23 Molodets. The United States planned and started development of an analogue, the Peacekeeper Rail Garrison, but abandoned the plan with the end of the Cold War. Similar systems were tested by China in 2016 and North Korea in 2021.
ICBMs are large, and not easily mobile. For this reason, they are traditionally launched from fixed missile silos. However, keeping missiles in fixed positions leaves them vulnerable to a pre-emptive nuclear strike. [1] For strategic deterrence, nuclear-armed nations seek to ensure mutually assured destruction, meaning that if one nation launches a nuclear first strike, the target nation would still be able to launch a retaliatory nuclear strike. [2]
Rail-mobile ICBM systems are harder to destroy than fixed positions, as they can travel anywhere along a nation's rail network, and hide from satellite surveillance in tunnels. [1] [3] During times of heightened international tensions, railroad based ICBMs can be rapidly mobilized and spread out across a country's railroad network as an insurance policy. [3]
Railroad-based ICBMs also have several drawbacks. While basing them on railroad tracks makes them flexible, they are still limited by where railroad tracks exist. [2] Railroad tracks are also vulnerable to sabotage, which would be a major concern during times of war. [2] It is also difficult to maintain security along vast railroad networks, even during peacetime. [2]
The USSR was the first nation to develop an ICBM system that was mobile by rail. Named the RT-23 Molodets, the system was deployed on specially designed trains in the 1980s on the Soviet rail network. [2]
In the 1980s, military planners in the United States conceived the Peacekeeper Rail Garrison as a means of pairing LGM-118 Peacekeeper missiles with the mobility of a train. The missiles would be disguised as normal boxcars and carried on dedicated trains operated by the United States Air Force, with an initial inventory of 25 trains, each carrying two Peacekeepers. [4]
In a 1988 article in Air Force Magazine, a defense analyst described the benefits of a rail based ICBM system:
"Peacekeeper ICBMs mounted on railway cars can also disperse beyond the limits of the Soviet ICBM threat if given any kind of warning time. Within three hours after dispersal has begun, the attack price to the USSR for destroying the Peacekeeper rail-mobile force would exceed the entire projected SS-18 warhead inventory. Trying to target US mobile ICBM forces as they dispersed—along with other triad elements and fixed US targets—would be a targeting nightmare for Soviet warplanners." [3]
The Cold War came to an end while the system was still in development, and as a result the program was cancelled to reduce costs, with one prototype Peacekeeper Rail Garrison car preserved at the National Museum of the United States Air Force. [4]
China performed a cold launch test of a railroad based ICBM system in December 2016, which is equipped with the country's DF-41 missile and operated by the People's Liberation Army Rocket Force. [5]
In September 2021, North Korea tested a new rail-based ICBM system, and released photos of it firing a missile. [1] A North Korean official said of the system, "The railway-borne missile system serves as an efficient counter-strike means capable of dealing a harsh multi-concurrent blow to the threat-posing forces." [6] The country has stated it plans to create a brigade of railroad based ICBM launchers in the near future. [6]
An intercontinental ballistic missile (ICBM) is a ballistic missile with a minimum range of 5,000 kilometres (3,100 mi) primarily designed for nuclear weapons delivery. 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, the United States, China, France, India, the United Kingdom, and North Korea are the only countries known to have operational ICBMs; Israel is believed to possess them as well.
Strategic Air Command (SAC) was both a United States Department of Defense (DoD) Specified Command and a United States Air Force (USAF) Major Command (MAJCOM), responsible for Cold War command and control of two of the three components of the U.S. military's strategic nuclear strike forces, the so-called "nuclear triad", with SAC having control of land-based strategic bomber aircraft and intercontinental ballistic missiles or ICBMs.
In nuclear strategy, a first strike or preemptive strike is a preemptive surprise attack employing overwhelming force. First strike capability is a country's ability to defeat another nuclear power by destroying its arsenal to the point where the attacking country can survive the weakened retaliation while the opposing side is left unable to continue war. The preferred methodology is to attack the opponent's strategic nuclear weapon facilities, command and control sites, and storage depots first. The strategy is called counterforce.
The LGM-30 Minuteman is an American land-based intercontinental ballistic missile (ICBM) in service with the Air Force Global Strike Command. As of 2021, the LGM-30G Minuteman III version 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 submarine-launched ballistic missile (SLBM) and nuclear weapons carried by long-range strategic bombers.
Vandenberg Space Force Base, previously Vandenberg Air Force Base, is a United States Space Force Base in Santa Barbara County, California. Established in 1941, Vandenberg Space Force Base is a space launch base, launching spacecraft from the Western Range, and also performs missile testing. The United States Space Force's Space Launch Delta 30 serves as the host delta for the base. In addition to its military space launch mission, Vandenberg Space Force Base also performs space launches for civil and commercial space entities, such as NASA and SpaceX.
The LGM-118 Peacekeeper, originally known as the MX for "Missile, Experimental", was a MIRV-capable intercontinental ballistic missile (ICBM) produced and deployed by the United States from 1985 to 2005. The missile could carry up to twelve Mark 21 reentry vehicles, each armed with a 300-kiloton W87 warhead. Initial plans called for building and deploying 100 MX ICBMs, but budgetary concerns eliminated the final procurement; only 50 entered service. Disarmament treaties signed after the Peacekeeper's development led to its withdrawal from service in 2005.
The RT-2PM Topol is a mobile intercontinental ballistic missile designed in the Soviet Union and in service with Russia's Strategic Missile Troops. As of 2014, Russia planned to replace all SS-25 ICBMs with versions of Topol-M.
The RT-23 Molodets was a cold-launched, three-stage, solid-fueled intercontinental ballistic missile developed and produced before 1991 by the Yuzhnoye Design Bureau in Dnipro, Ukraine. It came in silo- and rail-based variants, and was armed with 10 MIRV warheads of 550 kt yield. All missiles were decommissioned by 2005 in accordance with the START II.
The People's Liberation Army Rocket Force, formerly the Second Artillery Corps, is the strategic and tactical missile force of the People's Republic of China. The PLARF is the 4th branch of the People's Liberation Army (PLA) and controls China's arsenal of land-based ballistic missiles—both nuclear and conventional. The armed service branch was established on 1 July 1966 and made its first public appearance on 1 October 1984. The headquarters for operations is located at Qinghe, Beijing. The PLARF is under the direct command of the Chinese Communist Party's Central Military Commission (CMC).
The MGM-134A Midgetman, also known as the Small Intercontinental Ballistic Missile, was an intercontinental ballistic missile developed by the United States Air Force. The system was mobile and could be set up rapidly, allowing it to move to a new firing location after learning of an enemy missile launch. To attack the weapon, the enemy would have to blanket the area around its last known location with multiple warheads, using up a large percentage of their force for limited gains and no guarantee that all of the missiles would be destroyed. In such a scenario, the U.S. would retain enough of their forces for a successful counterstrike, thereby maintaining a deterrence.
A nuclear triad is a three-pronged military force structure that consists of land-launched nuclear missiles, nuclear-missile-armed submarines, and strategic aircraft with nuclear bombs and missiles. Specifically, these components are land-based intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and strategic bombers. The purpose of having this three-branched nuclear capability is to significantly reduce the possibility that an enemy could destroy all of a nation's nuclear forces in a first-strike attack. This, in turn, ensures a credible threat of a second strike, and thus increases a nation's nuclear deterrence.
The Dongfeng-41 is a fourth-generation Chinese solid-fuelled road-mobile intercontinental ballistic missile operated by the People's Liberation Army Rocket Force. DF-41 is the fourth and the latest generation of the Dongfeng series strategic missiles developed by China. The missile was officially unveiled at the China National Day military parade on 1 October 2019.
A missile launch facility, also known as an underground missile silo, launch facility (LF), or nuclear silo, is a vertical cylindrical structure constructed underground, for the storage and launching of intercontinental ballistic missiles (ICBMs), intermediate-range ballistic missiles (IRBMs), medium-range ballistic missiles (MRBMs). Similar facilities can be used for anti-ballistic missiles (ABMs).
A missile combat crew (MCC), is a team of highly trained specialists, often called missileers, staffing Intermediate Range and Intercontinental ballistic missile systems. In the United States, personnel, officially coded as Nuclear and Missile Operations Officers, of the United States Air Force, operate underground missile systems at launch control centers located throughout the country. There are also a select few missileers that have the chance to become part of a Missile Combat Crew-Airborne (MCC-A) operating the Airborne Launch Control System which provides a survivable launch capability for the Minuteman ICBM force. Crew size varied among the different missile systems, but the number was always greater than one, to abide by USSTRATCOM's two-man rule for positive control of nuclear weapons.
The Peacekeeper Rail Garrison was a railcar-launched ICBM that was developed by the United States Air Force during the 1980s as part of a plan to place fifty MGM-118A Peacekeeper intercontinental ballistic missiles on the rail network of the United States. The railcars were intended, in case of increased threat of nuclear war, to be deployed onto the nation's rail network to avoid being destroyed by a first strike counterforce attack by the Soviet Union. However, the plan was canceled as part of defense cutbacks following the end of the Cold War, and the Peacekeeper missiles were installed in silo launchers as LGM-118s instead.
In nuclear strategy, a counterforce target is one that has a military value, such as a launch silo for intercontinental ballistic missiles, an airbase at which nuclear-armed bombers are stationed, a homeport for ballistic missile submarines, or a command and control installation.
STRAT-X, or Strategic-Experimental, was a U.S. government-sponsored study conducted during 1966 and 1967 that comprehensively analyzed the potential future of the U.S. nuclear deterrent force. At the time, the Soviet Union was making significant strides in nuclear weapons delivery, and also constructing anti-ballistic missile defenses to protect strategic facilities. To address a potential technological gap between the two superpowers, U.S. Secretary of Defense Robert McNamara entrusted the classified STRAT-X study to the Institute for Defense Analyses, which compiled a twenty-volume report in nine months. The report looked into more than one hundred different weapons systems, ultimately resulting in the MGM-134 Midgetman and LGM-118 Peacekeeper intercontinental ballistic missiles, the Ohio-class submarines, and the Trident submarine-launched ballistic missiles, among others. Journalists have regarded STRAT-X as a major influence on the course of U.S. nuclear policy.
A Minuteman Mobility Test Train was a Cold War train for Strategic Air Command testing before deployment of planned trains for launching Minuteman missiles which were to allow periodic movement for security from targeting by the Soviet missile force. At the time, the trains had the heaviest railroad cars used on regular rail routes, and rail sidings were surveyed during the trains' 1960 Operation Big Star
The RS-27 (?) or SS-X-32Zh (?) Barguzin BZhRK (БЖРК) Project is a rail-mobile intercontinental ballistic missile (ICBM) under development for the Russian RVSN, as a replacement of the previous railway missile train Molodets BZhRK SS-24 Scalpel. BZhRK stands for railway strategic missile train. The missile was expected to enter testing in 2019 and enter service in 2020.
