155 Mm Howitzer M1
The 155 mm Howitzer M114 is a towed howitzer developed and used by the United States Army. It was first produced in 1941 as a medium artillery piece under the designation of 155 mm Howitzer M1. It saw service with the US Army during World War II, the Korean War, and the Vietnam War, before being replaced by the M198 howitzer. The gun was also used by the armed forces of many nations. The M114A1 remains in service in some countries. Development Early development After the end of the First World War a board later named the Westervelt Board after its president, Brigadier General William I. Westervelt, was convened to assess the artillery experience of the combatant powers and map out future directions for the US Army artillery. The conclusion of the board vis-a-vis corps (heavy field) artillery was that an ideal heavy howitzer should have range of at least and allow the elevation of 65°B. P.

Field Artillery
Field artillery is a category of mobile artillery used to support army, armies in the field. These weapons are specialized for mobility, tactical proficiency, short range, long range, and extremely long range target engagement. Until the early 20th century, field artillery were also known as foot artillery, for while the guns were pulled by Working animal, beasts of burden (often horses), the gun crews would usually march on foot, thus providing fire support mainly to the infantry. This was in contrast to horse artillery, whose emphasis on speed while supporting cavalry units necessitated lighter guns and crews riding on horseback. Whereas horse artillery has been superseded by self-propelled artillery, field artillery has survived to this day both in name and mission, albeit with motor vehicles towing the guns (this towed artillery arrangement is often called mobile artillery), carrying the crews and transporting the ammunition. Modern artillery has also advanced to rapidly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interrupted Screw
file:Breech 122m10 hameenlinna 2.jpg, Breech from Russian 122 mm M1910 howitzer, modified and combined with 105 mm H37 howitzer barrel An interrupted screw or interrupted thread is a mechanical device typically used in the Breech-loading weapon, breech of artillery guns. It is believed to have been invented in 1845. The system has also been used to close other devices, including the joint between helmet (bonnet) and breastplate (corselet) of standard diving suit helmets, and the locks of diving chambers. Design An interrupted screw has a section of thread along its axis removed. The screw is mated with a partially threaded hole in the receptacle: threadless channels in the breechblock screw line up with the threaded parts of the receptacle, and vice versa. The screw can thus be smoothly inserted all the way into the receptacle, after which as little as one-eighth of a turn can engage the two sets of threads securely, sealing the joint. The amount of rotation required ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

V-J Day
Victory over Japan Day (also known as V-J Day, Victory in the Pacific Day, or V-P Day) is the day on which Imperial Japan surrendered in World War II, in effect bringing the war to an end. The term has been applied to both of the days on which the initial announcement of Japan's surrender was made – August 15 1945, in Japan, and because of time zone differences, 14 August 1945 (when it was announced in the United States and the rest of the Americas and Eastern Pacific Islands) – as well as to September 2 1945, when the surrender document was signed, officially ending World War II. August 15 is the official V-J Day for the United Kingdom, while the official US commemoration is September 2. The name, V-J Day, had been selected by the Allies after they named V-E Day for the victory in Europe. On September 2 1945, formal surrender occurred aboard the battleship USS ''Missouri'' in Tokyo Bay. In Japan, August 15 usually is known as the ; the official name for the day, ho ...

Equilibrator
A gun carriage is a frame or a mount that supports the gun barrel of an artillery piece, allowing it to be maneuvered and fired. These platforms often had wheels so that the artillery pieces could be moved more easily. Gun carriages are also used on ships to facilitate the movement and aiming of large cannons and guns. These are also used in the funeral procession of any higher authority of any state and country. Early guns The earliest guns were laid directly onto the ground, with earth being piled up under the muzzle end of the barrel to increase the elevation. As the size of guns increased, they began to be attached to heavy wooden frames or beds that were held down by stakes. These began to be replaced by wheeled carriages in the early 16th century. Smoothbore gun carriages From the 16th to the mid-19th century, the main form of artillery remained the smoothbore cannon. By this time, the trunnion (a short axle protruding from either side of the gun barrel) had been develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
