Air-launched Ballistic Missile
An air-launched ballistic missile or 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 1990's 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 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GAM-87 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 int ...

Anti-satellite Missile
Anti-satellite weapons (ASAT) are space weapons designed to incapacitate or destroy satellites for strategic or tactical purposes. Several nations possess operational ASAT systems. Although no ASAT system has been utilised in warfare, a few countries (China, India, Russia, United Kingdom and the United States) have successfully shot down their own satellites to demonstrate their ASAT capabilities in a show of force. ASATs have also been used to remove decommissioned satellites. ASAT roles include: defensive measures against an adversary's space-based and nuclear weapons, a force multiplier for a nuclear first strike, a countermeasure against an adversary's anti-ballistic missile defence (ABM), an asymmetric counter to a technologically superior adversary, and a counter-value weapon. Use of ASATs generates space debris, which can collide with other satellites and generate more space debris. A cascading multiplication of space debris could cause Earth to suffer from Kes ...

B-47 Stratojet
The Boeing B-47 Stratojet (Boeing company designation Model 450) is a retired American long-range, six-engined, turbojet-powered strategic bomber designed to fly at high subsonic speed and at high altitude to avoid enemy interceptor aircraft. The primary mission of the B-47 was as a nuclear bomber capable of striking targets within the Soviet Union. Development of the B-47 can be traced back to a requirement expressed by the United States Army Air Forces (USAAF) in 1943 for a reconnaissance bomber that harnessed newly developed jet propulsion. Another key innovation adopted during the development process was the swept wing, drawing upon captured German research. With its engines carried in nacelles underneath the wing, the B-47 represented a major innovation in post-World War II combat jet design, and contributed to the development of modern jet airliners. Suitably impressed, in April 1946, the USAAF ordered two prototypes, designated "XB-47"; on 17 December 1947, the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bold Orion
The Bold Orion missile, also known as Weapons System 199B (WS-199B), was a prototype air-launched ballistic missile (ALBM) developed by Martin Aircraft during the 1950s. Developed in both one- and two-stage designs, the missile was moderately successful in testing, and helped pave the way for development of the GAM-87 Skybolt ALBM. In addition, the Bold Orion was used in early anti-satellite weapons testing, performing the first interception of a satellite by a missile. Design and development The Bold Orion missile was developed as part of Weapons System 199, initiated by the United States Air Force (USAF) in response to the U.S. Navy's Polaris program, with funding authorised by the United States Congress in 1957.Yengst 2010, p.37. The purpose of WS-199 was the development of technology that would be used in new strategic weapons for the USAF's Strategic Air Command, not to deliver operational weapons; a primary emphasis was on proving the feasibility of an air-launched ballist ...

Martin Aircraft
The Glenn L. Martin Company—also known as The Martin Company from 1957-1961—was an American aircraft and aerospace manufacturing company founded by aviation pioneer Glenn L. Martin, and operated between 1917-1961. The Martin Company produced many important aircraft for the defense of the US and allies, especially during World War II and the Cold War. During the 1950s and 60s, the Martin Company moved from the aircraft industry into the guided missile, space exploration, and space utilization industries. In 1961, the Martin Company merged with American-Marietta Corporation, a large industrial conglomerate, forming Martin Marietta Corporation. In 1995, Martin Marietta merged with aerospace giant Lockheed to form the Lockheed Martin Corporation."Lockheed Martin History." ''lockheedmartin.com.'' Retrieve ...

Cargo Aircraft
A cargo aircraft (also known as freight aircraft, freighter, airlifter or cargo jet) is a fixed-wing aircraft that is designed or converted for the carriage of air cargo, cargo rather than passenger aircraft, passengers. Such aircraft usually do not incorporate passenger amenities and generally feature one or more large doors for loading cargo. Freighters may be operated by civil passenger or cargo airlines, by private individuals or by the armed forces of individual countries. Aircraft designed for cargo flight usually have features that distinguish them from conventional passenger aircraft: a wide/tall fuselage cross-section, a high-wing to allow the cargo area to sit near the ground, numerous wheels to allow it to land at unprepared locations, and a high-mounted tail to allow cargo to be driven directly into and off the aircraft. By 2015, dedicated freighters represent 43% of the 700 billion ATK (available tonne-kilometer) capacity, while 57% is carried in Airliner#Baggage ...

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 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the 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 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 globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UGM-27 Polaris
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 be g ...

The United States Navy traces its origins to the Continental Navy, which was established during the American Revolut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intercontinental Ballistic Missile
An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than , primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads). 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. Early ICBMs had limited precision, which made them suitable for use only against the largest targets, such as cities. They were seen as a "safe" basing option, one that would keep the deterrent force close to home where it would be difficult to attack. Attacks against military targets (especially hardened ones) still demanded th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
