Bunker Buster
A bunker buster is a type of munition that is designed to penetrate hardened targets or targets buried deep underground, such as military bunkers. Armor piercing shells Germany Röchling shells were bunker-busting artillery shells, developed by the German engineer August Cönders, based on the theory of increasing sectional density to improve penetration. They were tested in 1942 and 1943 against the Belgian Fort d'Aubin-Neufchâteau. Aircraft delivered bombs World War II Germany In World War II the Luftwaffe developed a series of unguided rocket-propelled armor-piercing bombs for use against shipping and fortifications. United Kingdom In World War II, the British designer Barnes Wallis, already famous for inventing the bouncing bomb, designed two bombs that would become the conceptual predecessors of modern bunker busters: the five tonne Tallboy and the ten tonne Grand Slam. These were "Earthquake" bombs—a concept he had first proposed in 1939. The designs we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Munition
Ammunition (informally ammo) is the material fired, scattered, dropped, or detonated from any weapon or weapon system. Ammunition is both expendable weapons (e.g., bombs, missiles, grenades, land mines) and the component parts of other weapons that create the effect on a target (e.g., bullets and warheads). The purpose of ammunition is to project a force against a selected target to have an effect (usually, but not always, lethal). An example of ammunition is the firearm cartridge, which includes all components required to deliver the weapon effect in a single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds. Ammunition comes in a great range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain ammunition types (e.g., 5.56×45mm NATO) that enable their use across different we ...

Camouflet
A camouflet, in military science, is an artificial cavern created by an explosion. If the explosion reaches the surface then it is called a subsidence crater, crater. The term was originally defined as a countermine dug by defenders to prevent the Mining (military), undermining of a fortress's walls during a siege. The defenders would dig a tunnel under the attackers' tunnel. An explosive charge would be detonated to create a camouflet that would collapse the attackers' tunnel. More recently, the term has been used to describe the effects of very large bombs like the Grand Slam bomb, which are designed to penetrate next to a large target structure and create a camouflet to undermine the foundations of the structure. It has been observed that it is more efficient to penetrate ground next to the target than to hit the target directly. A camouflet set describes a system used in the British Army for cratering tracks and other routes. A tube is driven into the ground using a manual pos ...

USAF MOP Test Release Crop
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control. The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force through the Department of the Air Force is headed by the civilian Secretary of the Air Force ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kanggye
Kanggye () is the provincial capital of Chagang, North Korea and has a population of 251,971. Because of its strategic importance, derived from its topography, it has been of military interest from the time of the Joseon Dynasty (1392-1910). History In December 1949, Kanggye-myon was promoted to Kanggye-si. During the Korean War, after being driven from Pyongyang, Kim Il Sung and his government temporarily moved the capital to Kanggye after first moving temporarily to Sinuiju. The city was firebombed in November 1950 on American general Douglas MacArthur's orders after the Chinese People's Volunteer Army turned the course of the war; at least 65% of the city was destroyed. The following month Kim presided over a plenum of the cabinet at Kanggye, where he assigned blame for what he claimed were military failures during the losing phase of the war. Workers' Party general secretary Kim Jong-il toured facilities at Kanggye and the surrounding area in January 1998 amid the North ...

Tarzon
The ASM-A-1 Tarzon, also known as VB-13, was a guided bomb developed by the United States Army Air Forces during the late 1940s. Mating the guidance system of the earlier Razon radio-controlled weapon with a British Tallboy bomb, the ASM-A-1 saw brief operational service in the Korean War before being withdrawn from service in 1951. Design and development Development of the VB-13 Tarzon began in February 1945, with Bell Aircraft being awarded a contract by the United States Army Air Forces for the development of a very large guided bomb.Parsch 2003Stumpf 1998, p.13. The VB-13 was a combination of a radio-command guidance system as used on the smaller VB-3 Razon ('Range And azimuth only') guided bomb with the British-developed Tallboy "earthquake" bomb,Schmitt 2002, p.45. known to the USAAF as M112.Gillespie 2006, p.54. The 'Tarzon' name was a portmanteau, combining Tallboy, range and azimuth only, describing the weapon and guidance system;NMUSAF Fact Sheet: VB-13 Tarzon Bomb an ...

Mach Number
Mach number (M or Ma) (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Moravian physicist and philosopher Ernst Mach. : \mathrm = \frac, where: : is the local Mach number, : is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and : is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number.

Royal Navy Volunteer Reserve
The Royal Naval Reserve (RNR) is one of the two volunteer reserve forces of the Royal Navy in the United Kingdom. Together with the Royal Marines Reserve, they form the Maritime Reserve. The present RNR was formed by merging the original Royal Naval Reserve, created in 1859, and the Royal Naval Volunteer Reserve (RNVR), created in 1903. The Royal Naval Reserve has seen action in World War I, World War II, the Iraq War, and War in Afghanistan. History Establishment The Royal Naval Reserve (RNR) has its origins in the Register of Seamen, established in 1835 to identify men for naval service in the event of war, although just 400 volunteered for duty in the Crimean War in 1854 out of 250,000 on the Register. This led to a Royal Commission on Manning the Navy in 1858, which in turn led to the Naval Reserve Act of 1859. This established the RNR as a reserve of professional seamen from the British Merchant Navy and fishing fleets, who could be called upon during times of w ...

Edward Terrell
Edward Terrell OBE (1902–1979) was a British Liberal politician, a successful barrister and magistrate with a flair for invention; by 1940 he had registered a number of patents relating to pens, ink bottles and peeling knives. When war came, he volunteered for the Royal Navy Volunteer Reserve (RNVR) and was commissioned as a lieutenant in the Special Branch of the Volunteer Reserve to run an information section. Early life He was the son of Thomas Terrell KC, who was a Liberal Member of Parliament. He graduated at London University and was called to the Bar by Gray's Inn in 1924. He first stood for Parliament at the 1929 General Election, when he was Liberal candidate for Watford. He came second, ahead of the Labour candidate. He did not contest the 1931 General Election but stood as Liberal candidate for Lambeth North at the 1935 General Election when he again finished second. From 1935 he was Recorder of Newbury. While still a civilian Terrell had outlined a scheme to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
