T-37 (rocket)
The 7.2-Inch Demolition Rocket, also known as the T37, was a rocket developed and used by the United States military during World War II. Derived from the "Mousetrap" anti-submarine rocket, it was intended for use in demolishing concrete bunkers and fortifications, and saw use from August 1944. Development The 7.2-Inch Demolition Rocket was developed by the Physical Chemical Problems branch of the National Defense Research Committee, located at Caltech, in late 1943 as a modification of the existing ASW rocket (Mousetrap) for use against heavily fortified ground targets. Assigned to the United States Navy for development and production in July 1944, An additional high-explosive rocket, the T24, was planned, but was dropped in favor of the T37. The rockets utilized a standard rocket motor, fitted with a larger-diameter warhead; a longer-ranged version utilizing a motor was also produced. Operational history The T37 saw its first operational use during Operation Dragoon, the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Army
The United States Army (USA) is the primary Land warfare, land service branch of the United States Department of Defense. It is designated as the Army of the United States in the United States Constitution.Article II, section 2, clause 1 of the United States Constitution (1789).See alsTitle 10, Subtitle B, Chapter 301, Section 3001 It operates under the authority, direction, and control of the United States Secretary of Defense, United States secretary of defense. It is one of the six armed forces and one of the eight uniformed services of the United States. The Army is the most senior branch in order of precedence amongst the armed services. It has its roots in the Continental Army, formed on 14 June 1775 to fight against the British for independence during the American Revolutionary War (1775–1783). After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.Library of CongressJournals ...

Rocket Motor
A rocket engine is a reaction engine, producing thrust in accordance with Newton's third law by ejecting reaction mass rearward, usually a high-speed jet of high-temperature gas produced by the combustion of rocket propellants stored inside the rocket. However, non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum, and they can achieve great speed, beyond escape velocity. Vehicles commonly propelled by rocket engines include missiles, artillery shells, ballistic missiles and rockets of any size, from tiny fireworks to man-sized weapons to huge spaceships. Compared to other types of jet engine, rocket engines are the lightest and have the highest thrust, but are the least propellant-efficient (they have the lowest specific impulse). The ideal exhaust is hydrogen, the lightest of all elements, but chemical rockets produce a mix o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II Weapons Of The United States
The world is the totality of entities, the whole of reality, or everything that exists. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique, while others talk of a "plurality of worlds". Some treat the world as one simple object, while others analyze the world as a complex made up of parts. In scientific cosmology, the world or universe is commonly defined as "the totality of all space and time; all that is, has been, and will be". Theories of modality talk of possible worlds as complete and consistent ways how things could have been. Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon, or the "horizon of all horizons". In philosophy of mind, the world is contrasted with the mind as that which is represented by the mind. Theology conceptualizes the world in relation to God, for example, as God's creation, ...

Rocket Weapons Of The United States
A rocket (from , and so named for its shape) is a vehicle that uses jet propulsion to Acceleration, accelerate without using any surrounding Atmosphere of Earth, air. A rocket engine produces thrust by Reaction (physics), reaction to exhaust expelled at high speed. Rocket engines work entirely from rocket propellant, propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with Airbreathing jet engine, airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, Reaction control system, auxiliary reaction engines, gimballed thrust, Reaction wheel, momentum wheels, Thrust vectoring, deflection of ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th century, these hoods were known as turrets. Modern warships have gun-m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T40 Whizbang
The 7.2-inch Multiple Rocket Launcher T40/M17 ''Whizbang'' (sometimes spelled ''Whiz-Bang'' or ''Whiz Bang'') was a tank-mounted multiple rocket launcher used by the United States Army during World War II. The launcher was mounted atop 75mm variants of the M4 Sherman, and fired a barrage of rockets from 20 launch tubes. It was developed and used in the late stages of the war, and saw limited combat in 1944–45. Design The T40/M17 Whizbang could hold twenty 7.2-inch rockets in two racks of ten rockets each, housed in a box-like frame protected by hydraulically operated doors. These doors protected the rockets from enemy fire, reflecting that it was designed to be used at a close range. The launcher could be aimed by elevating the tank's main gun, and had two firing modes, enabling the operator to fire a single rocket, or a salvo of rockets at a selected rate of fire. After expending all the rockets, the operator could easily jettison the empty launcher by turning the turr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M4 Sherman
The M4 Sherman, officially medium tank, M4, was the medium tank most widely used by the United States and Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. It was also the basis of several other armored fighting vehicles including self-propelled artillery, tank destroyers, and armored recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Commonwealth, Soviet Union, and other Allied Nations. The tank was named by the British after the American Civil War General William Tecumseh Sherman. The M4 Sherman tank evolved from the M3 Lee, a medium tank developed by the United States during the early years of World War II. The M3, also known by its service names "Grant" and "Lee," was characterized by a unique design that featured the main armament mounted in a side sponson. The Grant variant, used by British forces, employed a lower-profile turret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-tank
Anti-tank warfare refers to the military strategies, tactics, and weapon systems designed to counter and destroy enemy armored vehicles, particularly tanks. It originated during World War I following the first deployment of tanks in 1916, and has since become a fundamental component of land warfare doctrine. Over time, anti-tank warfare has evolved to include a wide range of systems, from handheld infantry weapons and anti-tank guns to guided missiles and air-delivered munitions. Anti-tank warfare evolved rapidly during World War II, leading to infantry-portable weapons. Through the Cold War of 1947–1991, the United States, anti-tank weapons have also been upgraded in number and performance. Since the end of the Cold War in 1992, new threats to tanks and other armored vehicles have included remotely detonated improvised explosive devices (IEDs). During the Russian invasion of Ukraine, drones and loitering munitions have attacked and destroyed tanks. Tank threat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing Craft Rocket
The Landing Craft Tank (Rocket) or LCT(R) was developed from the British Mk.2 and Mk.3 Landing Craft Tank (LCT) during the Second World War. It was designed to saturate beaches with either 972 or 1,044 rockets prior to the landing of troops. Used by both British and U.S. forces, the craft saw service in the Normandy landings, the Mediterranean and the Far East. Design The front loading door was welded shut and an additional deck installed above the tank storage bay to provide a mounting for the rocket launching racks. The resulting storage space below the deck (formerly the tank deck) was informally subdivided with canvas sheets to provide additional crew space. These were later updated with wooden partitions. The craft was also fitted with a Type 970 radar set whose primary use was for rangefinding, but was also successfully used for navigation. Generally propulsion was provided by Paxman diesel engines, however, others were used due to availability. Some U.S. craft were ...

Operation Dragoon
Operation Dragoon (initially Operation Anvil), known as Débarquement de Provence in French ("Provence Landing"), was the code name for the landing operation of the Allies of World War II, Allied invasion of Provence (Southern France) on 15August 1944. Although initially designed to be executed in conjunction with Operation Overlord, the June 1944 Normandy landings, Allied landing in Normandy, the lack of enough resources led to the cancellation of the second landing. By July 1944 the landing was reconsidered, as the clogged-up ports in Normandy did not have the capacity adequately to supply the Allied forces. Concurrently, the high command of the French Liberation Army pushed for a revival of the operation, which would involve large numbers of French troops. As a result, the operation was finally approved in July to be executed in August. The invasion sought to secure the vital ports on the French Mediterranean coast and increase pressure on the German forces by opening another ...

Warhead
A warhead is the section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket (weapon), rocket, torpedo, or bomb. Classification Types of warheads include: *Explosive material, Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave. **Conventional weapon, 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 wave, Blast: A strong shock wave is provided by the detonation of the explosive. ***Fragmentation (weaponry), Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. ***Continuous-rod warhead, Continuous rod: Metal bars welded on their ends ...

High-explosive Fragmentation
A shell, in a modern military context, is a projectile whose payload contains an explosive, incendiary, or other chemical filling. Originally it was called a bombshell, but "shell" has come to be unambiguous in a military context. A shell can hold a tracer. All explosive- and incendiary-filled projectiles, particularly for mortars, were originally called ''grenades'', derived from the French word for pomegranate, so called because of the similarity of shape and that the multi-seeded fruit resembles the powder-filled, fragmentizing bomb. Words cognate with ''grenade'' are still used for an artillery or mortar projectile in some European languages. Shells are usually large-caliber projectiles fired by artillery, armoured fighting vehicles (e.g. tanks, assault guns, and mortar carriers), warships, and autocannons. The shape is usually a cylinder topped by an ogive-tipped nose cone for good aerodynamic performance, and possibly with a tapered boat tail; but some specialized ...
