A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and used by an individual. The term is legally defined further in different countries.
Gerald Vincent Bull was a Canadian engineer who developed long-range artillery. He moved from project to project in his quest to economically launch a satellite using a huge artillery piece, to which end he designed the Project Babylon "supergun" for Saddam Hussein's government in Iraq.
A railgun or rail gun is a linear motor device, typically designed as a weapon, that uses electromagnetic force to launch high-velocity projectiles. The projectile normally does not contain explosives, instead relying on the projectile's high kinetic energy to inflict damage. The railgun uses a pair of parallel conductors (rails), along which a sliding armature is accelerated by the electromagnetic effects of a current that flows down one rail, into the armature and then back along the other rail. It is based on principles similar to those of the homopolar motor.
A recoilless rifle (rifled), recoilless launcher (smoothbore), or simply recoilless gun, sometimes abbreviated to "RR" or "RCL" is a type of lightweight artillery system or man-portable launcher that is designed to eject some form of countermass such as propellant gas from the rear of the weapon at the moment of firing, creating forward thrust that counteracts most of the weapon's recoil. This allows for the elimination of much of the heavy and bulky recoil-counteracting equipment of a conventional cannon as well as a thinner-walled barrel, and thus the launch of a relatively large projectile from a platform that would not be capable of handling the weight or recoil of a conventional gun of the same size. Technically, only devices that use spin-stabilized projectiles fired from a rifled barrel are recoilless rifles, while smoothbore variants are recoilless guns. This distinction is often lost, and both are often called recoilless rifles.
Project HARP, short for High Altitude Research Project, was a joint venture of the United States Department of Defense and Canada's Department of National Defence created with the goal of studying ballistics of re-entry vehicles and collecting upper atmospheric data for research. Unlike conventional space launching methods that rely on rockets, HARP instead used very large guns to fire projectiles into the atmosphere at extremely high speeds.
A driving band or rotating band is a band of soft metal near the base of an artillery shell, often made of gilding metal, copper, or lead. When the shell is fired, the pressure of the propellant swages the metal into the rifling of the barrel and forms a seal; this seal prevents the gases from blowing past the shell and engages the barrel's rifling to spin-stabilize the shell.
The GC-45 is a 155 mm howitzer designed by Gerald Bull's Space Research Corporation (SRC) in the 1970s. Versions were produced by a number of companies during the 1980s, notably in Austria and South Africa.
The V-3 (German: Vergeltungswaffe 3, was a German World War II large-caliber gun working on the multi-charge principle whereby secondary propellant charges are fired to add velocity to a projectile. It was built in tunnels and was permanently aimed at London, England.
The formal definition of large-calibre artillery used by the United Nations Register of Conventional Arms (UNROCA) is "guns, howitzers, artillery pieces, combining the characteristics of a gun, howitzer, mortar, or rocket, capable of engaging surface targets by delivering primarily indirect fire, with a calibre of 76.2 mm (3.00 in) and above". This definition, shared by the Arms Trade Treaty and the Treaty on Conventional Armed Forces in Europe, is updated from an earlier definition in United Nations General Assembly Resolution 46/36L, which set a threshold of 100 mm (3.9 in). Several grammatical changes were made to that latter in 1992 and the threshold was lowered in 2003 to yield the current definition, as endorsed by UN General Assembly Resolution 58/54.
The Paris Gun was the name given to a type of German long-range siege gun, several of which were used to bombard Paris during World War I. They were in service from March to August 1918. When the guns were first employed, Parisians believed they had been bombed by a high-altitude Zeppelin, as the sound of neither an airplane nor a gun could be heard. They were the largest pieces of artillery used during the war by barrel length, and qualify under the (later) formal definition of large-calibre artillery. Also called the "Kaiser Wilhelm Geschütz", they were often confused with Big Bertha, the German howitzer used against Belgian forts in the Battle of Liège in 1914; indeed, the French called them by this name as well. They were also confused with the smaller "Langer Max" cannon, from which they were derived. Although the famous Krupp-family artillery makers produced all these guns, the resemblance ended there.
The Gyrojet is a family of unique firearms developed in the 1960s named for the method of gyroscopically stabilizing its projectiles. Rather than inert bullets, Gyrojets fire small rockets called Microjets which have little recoil and do not require a heavy barrel or chamber to resist the pressure of the combustion gases. Velocity on leaving the tube was very low, but increased to around 1,250 feet per second (380 m/s) at 30 feet (9.1 m). The result is a very lightweight and transportable weapon.
The Fist of God is a 1994 suspense novel by British writer Frederick Forsyth, with a fictitious retelling of the Iraqi Project Babylon and the resulting "supergun".
A space gun, sometimes called a Verne gun because of its appearance in From the Earth to the Moon by Jules Verne, is a method of launching an object into space using a large gun- or cannon-like structure. Space guns could thus potentially provide a method of non-rocket spacelaunch. It has been conjectured that space guns could place satellites into Earth's orbit, and could also launch spacecraft beyond Earth's gravitational pull and into other parts of the Solar System by exceeding Earth's escape velocity of about 11.20 km/s. However, these speeds are too far into the hypersonic range for most practical propulsion systems and also would cause most objects to burn up due to aerodynamic heating or be torn apart by aerodynamic drag. Therefore, a more likely future use of space guns would be to launch objects into Low Earth orbit, at which point attached rockets could be fired or the objects could be "collected" by maneuverable orbiting satellites.
Space Research Corporation was a corporation founded by Gerald Bull, after the budget for his research at Project HARP for the United States and Canadian federal governments was cut in 1967, in order to commercialize the technology of long-range artillery. Project HARP's assets were then given to the newly formed SRC.
The W33 was an American nuclear artillery shell designed for use in the 8-inch (203 mm) M110 howitzer and M115 howitzer.
Doomsday Gun is a 1994 television film produced by HBO, dramatizing the life of Canadian supergun designer Dr. Gerald Bull and his involvement in Project Babylon, Saddam Hussein's plan to build a supergun with a range of over 500 miles (800 km).
The Institute for Intelligence and Special Operations, popularly known as Mossad, is the national intelligence agency of the State of Israel. It is one of the main entities in the Israeli Intelligence Community, along with Aman and Shin Bet.
Jonathan Moyle, the 28-year-old editor of the magazine 'Defence Helicopter World' and former RAF helicopter pilot, was found dead in room 1406 of Santiago's Hotel Carrera on 31. March 1990. His purpose in Santiago was to attend a Chilean sponsored defence conference.
The "Supergun" affair was a 1990 political scandal in the United Kingdom that involved two businesses, Sheffield Forgemasters and Walter Somers, Gerald Bull, members of parliament Hal Miller and Nicholas Ridley, the UK's Secret Intelligence Service, a failed prosecution and components of a "supergun" that the businesses were alleged to have been exporting to Iraq that they and others had contacted the government about in 1988. The collapse of the court case preceded the Arms-to-Iraq case, that involved a different company Matrix Churchill, by four months.
The infernal machine is a homemade 25-barrel volley gun built by Giuseppe Marco Fieschi and used in Fieschi's failed assassination attempt on King Louis Philippe I of France on July 28, 1835. The original gun is now on display at the Musée des Archives Nationales in Paris, France.
