Chevaline2
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. Chevaline used a variety of penetration aids and decoys to offer so many indistinguishable targets that an opposing ABM system would be overwhelmed attempting to deal with them all, ensuring that enough warheads would get through an ABM defence to be a reasonable deterrent to a first strike. The project was highly secret, and survived in secrecy through four different governments before being revealed in 1980. The system was in service from 1982 to 1996, when the Polaris A3T missiles it was fitted to were replaced with the T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penetration Aid
A penetration aid (or "penaid") is a device or tactic used to increase an intercontinental ballistic missile (ICBM) warhead's chances of penetrating a target's defenses. These can consist of both ''physical devices'' carried within the ICBM (as part of its payload), as well as ''tactics'' that accompany its launch or flight path, operate as either passive or active counters, and may include one or more of the following concepts: * The missile booster can have a short burn time, and/or (if existing) the MIRV bus carrying the nuclear warheads can have some form of stealth technology, thereby hindering detection before the warhead reentry vehicles are released. * MIRV and MRV (instead of single warhead missiles) themselves largely improve penetration since there are many more warheads to destroy than missiles, which may saturate the defensive system's stock of weapons. However, these technologies are very demanding since they require the ability to highly miniaturize both the physics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Countervalue
In military doctrine, countervalue is the targeting of an opponent's assets that are of value but not actually a military threat, such as cities and civilian populations. Counterforce is the targeting of an opponent's military forces and facilities. The ''Oxford English Dictionary'', 2nd ed., records the first use of the word in 1660 and the first use in the modern sense in 1965 in which it is described as a "euphemism for attacking cities". Theory In warfare, particularly nuclear warfare, enemy targets can be divided into two general types: counterforce military targets and countervalue civilian targets. Those terms were not used during the Second World War bombing of civilian populations and other targets that were not directly military. The rationale behind countervalue targeting is that if two sides have both achieved assured destruction capability, and the nuclear arsenals of both sides have the apparent ability to survive a wide range of counterforce attacks and carry out ...

Warhead
A warhead is the forward section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb. Classification Types of warheads include: *Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave. ** Conventional: Chemicals such as gunpowder and high explosives store significant energy within their molecular bonds. This energy can be released quickly by a trigger, such as an electric spark. Thermobaric weapons enhance the blast effect by utilizing the surrounding atmosphere in their explosive reactions. *** Blast: A strong shock wave is provided by the detonation of the explosive. ***Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. ***Continuous rod: Metal bars welded on their ends form a compact cylinder of interconnected rods, which is violently expanded into a contiguous zig-zag ...

Polaris Sales Agreement
The Polaris Sales Agreement was a treaty between the United States and the United Kingdom which began the UK Polaris programme. The agreement was signed on 6 April 1963. It formally arranged the terms and conditions under which the UGM-27 Polaris, Polaris missile system was provided to the United Kingdom. The United Kingdom had been planning to buy the air-launched GAM-87 Skybolt, Skybolt missile to extend the operational life of the British V bombers, but the United States decided to cancel the Skybolt program in 1962 as it no longer needed the missile. The crisis created by the cancellation prompted an emergency meeting between the President of the United States, John F. Kennedy, and the Prime Minister of the United Kingdom, Harold Macmillan, which resulted in the Nassau Agreement, under which the United States agreed to provide Polaris missiles to the United Kingdom instead. The Polaris Sales Agreement provided for the implementation of the Nassau Agreement. The United Stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polaris Missile
The UGM-27 Polaris missile was a two-stage solid-fueled nuclear-armed submarine-launched ballistic missile (SLBM). As the United States Navy's first SLBM, it served from 1961 to 1980. In the mid-1950s the Navy was involved in the Jupiter missile project with the U.S. Army, and had influenced the design by making it squat so it would fit in submarines. However, they had concerns about the use of liquid fuel rockets on board ships, and some consideration was given to a solid fuel version, Jupiter S. In 1956, during an anti-submarine study known as Project Nobska, Edward Teller suggested that very small hydrogen bomb warheads were possible. A crash program to develop a missile suitable for carrying such warheads began as Polaris, launching its first shot less than four years later, in February 1960. As the Polaris missile was fired underwater from a moving platform, it was essentially invulnerable to counterattack. This led the Navy to suggest, starting around 1959, that they b ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the World War II, Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority ...

Nassau Agreement
The Nassau Agreement, concluded on 21 December 1962, was an agreement negotiated between President of the United States, John F. Kennedy, and Harold Macmillan, the Prime Minister of the United Kingdom, to end the Skybolt Crisis. A series of meetings between the two leaders over three days in the Bahamas followed Kennedy's announcement of his intention to cancel the Skybolt air-launched ballistic missile project. The US agreed to supply the UK with Polaris submarine-launched ballistic missiles for the UK Polaris programme. Under an earlier agreement, the US had agreed to supply Skybolt missiles in return for allowing the establishment of a ballistic missile submarine base in the Holy Loch near Glasgow. The British Government had then cancelled the development of its medium-range ballistic missile, known as Blue Streak, leaving Skybolt as the basis of the UK's independent nuclear deterrent in the 1960s. Without Skybolt, the V-bombers of the Royal Air Force (RAF) were likely t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AGM-48 Skybolt
The Douglas GAM-87 Skybolt (AGM-48 under the 1962 Tri-service system) was an 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 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. The UK joined the Skybolt program in 1960, intending to use it on their V bomber force. When the design added a star tracker in addition to its inertial navigation system (INS) this meant that it could only be carried externally where the tracker could see the sky. This requirement along with the required ground clearance on takeoff limited it to the Avro Vulcan bomber. A number of design decisions in the W47 led the RAF to question its safety, so they in ...

Standoff Missile
Standoff weapons are missiles or bombs which may be launched from a distance sufficient to allow attacking personnel to evade the effect of the weapon or defensive fire from the target area. Typically, they are used against land- and sea-based targets in an offensive operation. The name is derived from their ability to engage the target while standing off outside the range at which the defenders are likely to engage the attacker. Typical stand-off weapons include cruise missiles, glide bombs and short-range ballistic missiles. Types of missiles * Air-Sol Moyenne Portée (French air-launched nuclear missile) * AGM-28 Hound Dog * AGM-69 SRAM * AGM-86 ALCM * AGM-129 ACM * AGM-154 JSOW * AGM-158 JASSM * AGM-181 LRSO * BrahMos * Babur * B61 nuclear bomb with mod-12 tail guidance kit. * Blue Steel * Umbani * DRDO SAAW * GAM-87 Skybolt * H-2 SOW * H-4 SOW * Ra'ad Mk-1 * Ra'ad Mk-2 * Takbir * Barq * Babur-1 * Babur-1A * Babur-2 * Babur-3 * GIDS REK * Joint Strike Miss ...

Blue Steel Missile
The Avro Blue Steel was a British air-launched, rocket-propelled nuclear armed standoff missile, built to arm the V bomber force. It allowed the bomber to launch the missile against its target while still outside the range of surface-to-air missiles (SAMs). The missile proceeded to the target at speeds up to Mach 3, and would trigger within 100 m of the pre-defined target point. Blue Steel entered service in 1963, by which point improved SAMs with longer range had greatly eroded the advantages of the design. A longer-range version, Blue Steel II, was considered, but cancelled in favour of the much longer-range GAM-87 Skybolt system from the US. When development of that system was cancelled in 1962, the V-bomber fleet was considered highly vulnerable. Blue Steel remained the primary British nuclear deterrent weapon until the Royal Navy started operating Polaris ballistic missiles from ''Resolution''-class submarines. Development Blue Steel was the result of a Ministr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
