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 Coenders, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth Quake Bomb
The earthquake bomb, or seismic bomb, was a concept that was invented by the British aeronautical engineer Barnes Wallis early in World War II and subsequently developed and used during the war against strategic targets in Europe. A seismic bomb differs somewhat in concept from a traditional bomb, which usually explodes at or near the surface and destroys its target directly by explosive force; in contrast, a seismic bomb is dropped from high altitude to attain very high speed as it falls and upon impact, penetrates and explodes deep underground, causing massive caverns or craters known as '' camouflets'', as well as intense shockwaves. In this way, the seismic bomb can affect targets that are too massive to be affected by a conventional bomb, as well as damage or destroy difficult targets such as bridges and viaducts. Earthquake bombs were used towards the end of World War II on massively reinforced installations, such as submarine pens with concrete walls several meters thick, ...

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. Culture Attractions Kanggye is home to an open-air stadium and is also home to the Kanggye Riding Club, which was built in 2024. ...

Korean War
The Korean War (25 June 1950 – 27 July 1953) was an armed conflict on the Korean Peninsula fought between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK) and their allies. North Korea was supported by China and the Soviet Union, while South Korea was supported by the United Nations Command (UNC) led by the United States. The conflict was one of the first major proxy wars of the Cold War. Fighting ended in 1953 with an armistice but no peace treaty, leading to the ongoing Korean conflict. After the end of World War II in 1945, Korea, which had been a Korea under Japanese rule, Japanese colony for 35 years, was Division of Korea, divided by the Soviet Union and the United States into two occupation zones at the 38th parallel north, 38th parallel, with plans for a future independent state. Due to political disagreements and influence from their backers, the zones formed their governments in 1948. North Korea was led by Kim Il S ...

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 a ...

Mach Number
The Mach number (M or Ma), often only Mach, (; ) 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 Austrian 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). The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas. The Mach number is primarily used to determine the approximation with which a flow can be treated as an i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 the 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 and 1859, which in turn led to the Naval Reserve Act 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 ...

Disney Bomb
The Disney bomb, also known as the Disney Swish, officially the 4500 lb Concrete Piercing/Rocket Assisted bomb was a 4,500lb bunker buster bomb developed during the World War II, Second World War by the British Royal Navy to penetrate hardened concrete targets, such as submarine pens, which could resist conventional free-fall bombs. Devised by Royal Navy Captain Edward Terrell, the bomb was fitted with solid-fuel rockets to accelerate its descent, giving it an impact speed of —substantially beyond the free-fall impact velocity of the 5-tonne Tallboy (bomb), ''Tallboy'' "earthquake" bomb for comparable purposes. The Disney could penetrate of solid concrete before detonating. The name is attributed to a propaganda film, Victory Through Air Power (film)#Impact, ''Victory Through Air Power'', produced by the Walt Disney Animation Studios, Walt Disney Studios, a division of The Walt Disney Company, that provided the inspiration for the design.
