T18 Howitzer Motor Carriage
The T18 Howitzer Motor Carriage, abbreviated as HMC. was an American self-propelled gun. Its development started in September 1941 as a close-support vehicle using the M3 Stuart's chassis. A 75 mm howitzer was mounted on the right front of the vehicle. The gun mount was adapted from the M3 Grant. Two prototypes were produced by Firestone and then sent to the Aberdeen Proving Ground.Hunnicutt (1992), p. 320-21. Quote: "After inspection of the mock-up, Firestone was authorized to proceed with the construction of the two pilot vehicles." However, they were unsatisfactory because of their high superstructure and nose weight. Because the Army disliked the high superstructure and nearly vertical armor, the T18 was abandoned in 1942, and soon started a new turreted project, the T41 75 mm HMC, also known as the Howitzer Motor Carriage M8.Chamberlain & Ellis (1969), p. 90.Zaloga (1999), p. 19. Later, the prototypes were kept on display in the Aberdeen Proving Ground until they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-propelled Gun
Self-propelled artillery (also called locomotive artillery) is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and rocket artillery. They are high mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar, or some form of rocket/missile launcher. They are usually used for long-range indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and anti-tank guns (tank destroyers). These have been armoured vehicles, the former providing close fire-support for infantry and the latter acting as specialized anti-tank vehicles. Modern self-propelled artillery vehicles often mount their main gun in a turret on a tracked chassis so they superficially resemble tanks. However they are generally lightly armoured which ...

M116 Howitzer
The 75mm Pack Howitzer M1 (redesignated the M116 in 1962) was a pack howitzer artillery piece used by the United States. Designed to be moved across difficult terrain, gun and carriage could be broken down into several pieces to be carried by pack animals. The gun saw combat in World War II with the United States Army (primarily used by airborne units), with the United States Marine Corps, and was also supplied to foreign forces. In addition to the pack / air portable configuration, the gun was mounted on a conventional carriage to serve as a field artillery piece. The M2 and M3 are derived vehicle-mounted howitzers used in the 75mm HMC M8 and some LVT models. In addition, the M1 in its original version was mated to a number of other self-propelled carriages, though only one of those – 75mm HMC T30 – reached mass production. Development and production The 75 mm pack howitzer was designed in the United States in the 1920s to meet a need for an artillery piece that ...

United States Army
The United States Army (USA) is the land service branch of the United States Armed Forces. It is one of the eight U.S. uniformed services, and is designated as the Army of the United States in the U.S. Constitution.Article II, section 2, clause 1 of the United States Constitution (1789). See alsTitle 10, Subtitle B, Chapter 301, Section 3001 The oldest and most senior branch of the U.S. military in order of precedence, the modern U.S. Army has its roots in the Continental Army, which was formed 14 June 1775 to fight the American Revolutionary War (1775–1783)—before the United States was established as a country. 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 of the Continental Congress, Volume 27/ref> The United States Army considers itself to be a continuation of the Continental Army, and thus considers its institutional inception to be th ...

M3 Stuart
The M3 Stuart/Light Tank M3, was an American light tank of World War II. An improved version of the tank entered service as the M5 in 1942 to be supplied to British and other Commonwealth forces under lend-lease prior to the entry of the U.S. into the war. Afterwards, it was used by U.S. and Allied forces until the end of the war. The British service name "Stuart" came from the American Civil War Confederate general J. E. B. Stuart and was used for both the M3 and the derivative M5 Light Tank. Unofficially, were also often called "Honeys" by the British, because of their smooth ride. In U.S. use, the tanks were officially known as "Light Tank M3" and "Light Tank M5". Stuarts were first used in combat in the North African campaign; about 170 were used by the British forces in Operation Crusader (18 November – 30 December 1941). Stuarts were the first American-crewed tanks in World War II to engage the enemy in tank versus tank combat when used in the Philippines in Decemb ...

M3 Grant
The M3 Lee, officially Medium Tank, M3, was an American medium tank used during World War II. The turret was produced in two forms, one for US needs and one modified to British requirements to place the radio next to the commander. In British Commonwealth service, the tank was called by two names: tanks employing US pattern turrets were called "Lee," named after Confederate general Robert E. Lee, while those with British pattern turrets were known as "Grant," named after Union general Ulysses S. Grant. Design commenced in July 1940, and the first M3s were operational in late 1941. The US Army needed a medium tank armed with a 75mm gun and, coupled with the United Kingdom's immediate demand for 3,650 medium tanks, the Lee began production by late 1940. The design was a compromise meant to produce a tank as soon as possible. The M3 had considerable firepower and good armor, but had serious drawbacks in its general design and shape, including a high silhouette, an archaic sponso ...

Howitzer Motor Carriage M8
The 75 mm Howitzer Motor Carriage M8 was a self-propelled howitzer vehicle of the United States in use during World War II. It was developed on the chassis of the M5 Stuart tank and was equipped with a M116 howitzer in an M7 mount. Development and design Prototypes Experiments with a close-support version of the M3 Stuart began with the T18 Howitzer Motor Carriage. This essentially combined an M3 light tank chassis with the gun mount of a M3 Grant medium tank mounting the much smaller 75mm pack howitzer. This produced a tall design with the gun well forward, which led to the tank being nose-heavy. They also found the fighting compartment was too cramped and the cut-down sides provided no protection to the crew for shots anywhere but the front. The T18 was cancelled in 1942 in favor of a new design, the T41. This moved to the updated M5 chassis, differing from the M3 mostly in its engine, while introducing a new fighting compartment with a well-sloped front that provided more ...

Glacis Plate
A glacis (; ) in military engineering is an artificial slope as part of a medieval castle or in early modern fortresses. They may be constructed of earth as a temporary structure or of stone in more permanent structure. More generally, a glacis is any slope, natural or artificial, which fulfils the above requirements. The etymology of this French word suggests a slope made dangerous with ice, hence the relationship with ''glacier''. A ''glacis plate'' is the sloped front-most section of the hull of a tank or other armoured fighting vehicle. Ancient fortifications A glacis could also appear in ancient fortresses, such as the one the ancient Egyptians built at Semna in Nubia. Here it was used by them to prevent enemy siege engines from weakening defensive walls. Hillforts in Britain started to incorporate glacis around 350 BC. Those at Maiden Castle, Dorset were high. Medieval fortifications Glacis, also called talus, were incorporated into medieval fortifications to st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
