An air-launched ballistic missile (ALBM) is a ballistic missile launched from an aircraft. An ALBM allows the launch aircraft to stand off at long distances from its target, keeping it well outside the range of defensive weapons like anti-aircraft missiles and interceptor aircraft. Historically, once launched the missile was essentially immune to interception due to a lack of capable anti-ballistic missiles, with those few that did exist being limited to known static positions. This combination of features allowed a strategic bomber to present a credible deterrent second-strike option in an era when improving anti-aircraft defences appeared to be rendering conventional bombers obsolete. However, by the 1990s surface-to-air missile technology had innovated to the point of allowing the interception of such weapons (especially in their terminal phase) from road mobile systems, albeit at a lower PoK. By the early 21st century capable, dedicated, ABM systems from several nations had been deployed in significant numbers (with examples including upgraded MIM-104 Patriot and S-300, THAAD, SM-3, and S-400), spurring further innovation in hypersonic glide vehicles to penetrate such systems and keep ballistic missiles capable.

The ALBM concept was studied in the US as a way to ensure the usefulness and survivability of their large bomber fleet. After testing several experimental designs as part of the WS-199 efforts, the U.S. Air Force began development of the GAM-87 Skybolt missile with range on the order of 1,150 miles (1,850 km). The only other major force relying on strategic bombers was the Royal Air Force, who also selected the Skybolt to arm their V bomber fleet. The Soviet Union moved their strategic force directly to Intercontinental Ballistic Missiles.

Skybolt ultimately failed several key tests, while the US Navy's UGM-27 Polaris offered the same advantages and more. Skybolt was cancelled, leading to the Skybolt crisis and an agreement to sell Polaris to the Royal Navy as part of the Nassau Agreement. The concept saw little active development until the 1970s when ICBM warheads began to become accurate enough to attack other ICBMs while they were still on the ground. The US carried out several experiments using existing missile designs dropped from cargo aircraft, but ultimately abandoned this line of research entirely. No further strategic ALBM development has been carried out by the US, and this class of missile never saw active use.

High Virgo

The High Virgo, also known as Weapons System 199C (WS-199C), was a prototype air-launched ballistic missile (ALBM) jointly developed by Lockheed and the Convair division of General Dynamics during the late 1950s. The missile proved moderately successful and aided in the development of the later GAM-87 Skybolt ALBM. It was also used in early tests of anti-satellite weapons.

WS-199B Bold Orion

Developed by Martin Aircraft, the Bold Orion missile was an air-launched ballistic missile, launched from the B-47 Stratojet medium bomber, with flight tests being carried out in 1958 and 1959. Early launches of the Bold Orion as a single-stage vehicle were unsuccessful, however a redesign as a two-stage weapon produced improved results, with the remainder of the 12-launch series establishing the ALBM as a viable vehicle. The final test flight trialed the Bold Orion missile as an anti-satellite missile, passing within 4 miles (6.4 km) of Explorer VI, [1] the first-ever interception of a satellite. [2]

GAM-87 Skybolt

The GAM-87 Skybolt, intended to be launched from Boeing B-52 Stratofortress and Avro Vulcan bombers, was in development by the United States Air Force, with the United Kingdom as a customer. In 1962, with technical difficulties and costs mounting, the program was cancelled, with the United States and the UK concentrating on the UGM-27 Polaris submarine-launched ballistic missile instead.

Air Mobile Feasibility test: C-5 w/ LGM-30

In the early 1970s, the USAF tested air-launching a Minuteman 1b ICBM from a C-5A Galaxy transport aircraft. On 24 October 1974, the Space and Missile Systems Organization successfully conducted an Air Mobile Feasibility test where a C-5A Galaxy aircraft air-dropped the 86,000-pound missile from 20,000 feet over the Pacific Ocean. The missile fell to 8,000 feet before its rocket engine fired. The 10-second engine burn carried the missile to 20,000 feet again before it dropped into the ocean. The test proved the feasibility of launching an intercontinental ballistic missile from the air. Operational deployment was discarded due to engineering and security difficulties, though the capability was used as a negotiating point in the Strategic Arms Limitation Talks. [3] [4]

Kh-47M2 Kinzhal

In 2018, Russia unveiled an air-launched ballistic missile called Kh-47M2 Kinzhal with a range of 2,000 km (1,200 mi). It is suspected to be a version of the Iskander missile. Earlier Soviet aero-ballistic missiles have a much shorter range, e.g. Kh-15 only has a range of 300 km (190 mi). In March 2022, the Kinzhal was used for the first time in combat by Russia in Ukraine during its invasion of the country. [5]

Chinese DF-21 and DF-17

In March 2018, Defense Intelligence Agency chief Robert Ashley confirmed that China is developing two new air-launched ballistic missiles, one of which can carry a nuclear warhead. [6] The H-6K bomber would be suited to launch such missiles. One of these missiles is a derivative of the DF-21 called the CH-AS-X-13 and has a range of 3,000km.

In October 2020, a H-6 bomber was spotted at Neixiang Air Base landing with what appeared to be an air-launched ballistic missile similar to the DF-17. [7]

An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than 5,500 kilometres (3,400 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 vehicle (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. The United States, Russia, China, France, India, the United Kingdom, Israel, and North Korea are the only countries known to have operational ICBMs.

The Douglas GAM-87 Skybolt was a hypersonic air-launched ballistic missile (ALBM) developed by the United States during the late 1950s. The basic concept was to allow US strategic bombers to launch their weapons from well outside the range of Soviet defenses, as much as 1,000 miles (1,600 km) from their targets. To do this in an air-launched form, a lightweight thermonuclear warhead was needed. Initially, the W47 from the Polaris missile was selected, but it was later replaced by the W59 from the Minuteman missile.

<span class="mw-page-title-main">Ballistic missile</span> Missile that follows a sub-orbital ballistic flightpath

A ballistic missile (BM) is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are powered only during relatively brief periods—most of the flight is unpowered. Ballistic missiles differs in range; short-range ballistic missiles (SRBM) stay within the Earth's atmosphere, while intercontinental ballistic missiles (ICBM) are launched on a sub-orbital flight. They are internally guided, those for short range are typically inertial-guided while those for long range typically have more sophisticated guidance.

A multiple independently targetable reentry vehicle (MIRV) is an exoatmospheric ballistic missile payload containing several warheads, each capable of being aimed to hit a different target. The concept is almost invariably associated with intercontinental ballistic missiles carrying thermonuclear warheads, even if not strictly being limited to them. An intermediate case is the multiple reentry vehicle (MRV) missile which carries several warheads which are dispersed but not individually aimed. Only the United States, the United Kingdom, France, Russia and China are currently confirmed to have deployed MIRV missile systems. Pakistan is developing MIRV missile systems. Israel is suspected to possess or be in the process of developing MIRVs.

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 limited the final procurement; only 50 entered service. Disarmament treaties signed after the Peacekeeper's development led to its withdrawal from service in 2005.

An air-to-surface missile (ASM) or air-to-ground missile (AGM) is a missile designed to be launched from military aircraft at targets on land or sea. There are also unpowered guided glide bombs not considered missiles. The two most common propulsion systems for air-to-surface missiles are rocket motors, usually with shorter range, and slower, longer-range jet engines. Some Soviet-designed air-to-surface missiles are powered by ramjets, giving them both long range and high speed.

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.
