G7 Howitzer
The G7 is a South African 105 mm howitzer, produced by Denel Land Systems (DLS). With a maximum range of it outranges all existing 105 mm howitzers, as well as most current 155 mm howitzers (Denel's own 155's not included). During development, it was known as the ''Light Experimental Ordnance'' (LEO), with the G7 label being chosen later to fit in with Denel's two existing howitzer products, the G5 towed 155 mm howitzer and the G6 self-propelled 155 mm howitzer. Potential customers In 2004, DLS partnered with General Dynamics Land Systems (GDLS) to offer the gun in self-propelled form to the United States Army. GDLS provided an armoured vehicle (the LAV III), while Denel provided a G7 mounted inside a specially-designed, unmanned turret. The combined system weighs only 17.5 tons when fully loaded with ammunition, making it light enough to be transportable inside a C-130 Hercules transport aircraft. The combination took part in a number of tests for the US Army. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Base Bleed
Base bleed is a system used on some artillery shells to increase range, typically by about 20–35%. It expels gas into the low pressure area behind the shell to reduce base drag (it does not produce thrust). Since base bleed extends the range by a percentage, it is more useful on longer range artillery where an increase of approximately can be achieved. Until the late 1980s the small gains in range were not considered worthwhile for field artillery. Base bleed shells are becoming more common in units equipped with modern artillery with far greater range than older guns, but are usually only used when the longer range is required, due to their higher cost. Function Most (50–60%) of the drag on an artillery shell comes from the nose of the shell, as it pushes the air out of its way at supersonic speeds. Shaping the shell properly can reduce this drag. However, another powerful source of drag is the low-pressure area left behind the shell due to its blunt base. Base blee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stryker
The Stryker is a family of eight-wheeled armored fighting vehicles derived from the Canadian LAV III. Stryker vehicles are produced by General Dynamics Land Systems-Canada (GDLS-C) for the United States Army in a plant in London, Ontario. It has four-wheel drive (8×4) and can be switched to all-wheel drive (8×8). The Stryker was conceived as a family of vehicles forming the backbone of a new medium-weight brigade combat team (BCT) that was to strike a balance between heavy armor and infantry. The service launched the Interim Armored Vehicle competition, and in 2000, the service selected the LAV III proposed by GDLS and General Motors Defense. The service named this family of vehicles the "Stryker". Ten variants of the Stryker were initially conceived, some of which have been upgraded with v-hulls. Development history Interim Armored Vehicle competition In October 1999, General Eric Shinseki, then U.S. Army Chief of Staff, outlined a transformation plan for the Army tha ...

Field Artillery
Field artillery is a category of mobile artillery used to support 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 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 deployable wheeled a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
105 Mm Artillery
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Artillery
Artillery has been one of primary weapons of war since before the Napoleonic Era. Several countries have developed and built artillery systems, while artillery itself has been continually improved and redesigned to meet the evolving needs of the battlefield. This has led to a multitude of different types and designs which have played a role in the history of warfare and continue to be a significant factor in modern combat. For the most part, the following lists of artillery cover guns, howitzers, mortars, and other large projectile weapons. Small arms and missiles are not generally included, though rockets and other bombardment weapons may be.

Armscor (South Africa)
Armscor (stylized as ARMSCOR), the Armaments Corporation of South Africa is the arms procurement agency of the South African Department of Defence. It was originally established in 1968 as an arms production company, primarily as a response to the international sanctions by the United Nations against South Africa due to apartheid which began in 1963 and were formalised in 1977. History Until the 1970s, South Africa's apartheid government had placed a disproportionate emphasis on civilian law enforcement and the maintenance of internal security. However, a Cuban intervention in Angola, and the escalation of the South African Border War convinced the government that it faced a serious external threat. In 1978, the premiership was accepted by PW Botha, a former South African security chief, and defence expenditure spiraled upwards. Armscor, then a relatively new entity, was charged with modernising the arsenal of the South African Defence Force (SADF). This was a difficult task, as ...

South African Army
The South African Army is the principal land warfare force of South Africa, a part of the South African National Defence Force (SANDF), along with the South African Air Force, South African Navy and South African Military Health Service. The Army is commanded by the Chief of the Army, who is subordinate to the Chief of the SANDF. Formed in 1912, as the Union Defence Force in the Union of South Africa, through the amalgamation of the South African colonial forces following the unification of South Africa. It evolved within the tradition of frontier warfare fought by Boer Commando (militia) forces, reinforced by the Afrikaners' historical distrust of large standing armies. Following the ascension to power of the National Party, the Army's long-standing Commonwealth ties were afterwards cut. The South African Army was fundamentally changed by the end of Apartheid and its preceding upheavals, as the South African Defence Force became the SANDF. This process also led to ...

Rooikat AFV
The Rooikat (Afrikaans for "Caracal"; ) is a South African armoured reconnaissance vehicle equipped with a stabilised 76 mm high velocity gun for organic anti-tank and fire support purposes. The Rooikat's main armament was built with the Oto Melara 76 naval gun as its basis, to which it is nearly identical in terms of technical performance and statistics.''Jane's Armour and Artillery, 2001–2002'', Volume 23, pp. 244-345. The Rooikat can also fire the same ammunition as the naval gun, albeit modified with new percussion primers in the shells. Development history Background From the mid 1960s to the mid 1980s, the standard reconnaissance vehicle of the South African Defence Force was the Eland-90, a four-wheeled armoured car modelled closely after the Panhard AML-90. However, the Eland was designed for border patrols and internal security, and proved ill-suited to countering tank warfare.Warwick, Rodney.

United States Marine Corps
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is one of the eight uniformed services of the United States. The Marine Corps has been part of the U.S. Department of the Navy since 30 June 1834 with its sister service, the United States Navy. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers. The history of the Marine Corps began when two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia as ...

C-130 Hercules
The Lockheed C-130 Hercules is an American four-engine turboprop military transport aircraft designed and built by Lockheed Corporation, Lockheed (now Lockheed Martin). Capable of using unprepared runways for takeoffs and landings, the C-130 was originally designed as a troop, Medical evacuation, medevac, and Cargo aircraft, cargo transport aircraft. The versatile airframe has found uses in other roles, including as a gunship (AC-130), for airborne infantry, airborne assault, search and rescue, scientific research support, weather reconnaissance, aerial refueling, maritime patrol, and aerial firefighting. It is now the main tactical airlifter for many military forces worldwide. More than 40 variants of the Hercules, including civilian versions marketed as the Lockheed L-100, operate in more than 60 nations. The C-130 entered service with the U.S. in 1956, followed by Australia and many other nations. During its years of service, the Hercules has participated in numerous milita ...

Gun Carriage
A gun carriage is a frame and 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. 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 developed, with the result that the barrel could be held in two recesses in the carriage and secured with an iro ...
