Norinco AH4 155mm Howitzer
The AH4 howitzer is a Chinese 155 mm towed howitzer system manufactured by Norinco. Its main characteristic is that it has been designed to be lightweight, which allows greater tactical mobility. The weight of 4,500 kg, compared to a traditional system that can weigh 18,000 kg, allows the system to be airlifted via heavy-lift helicopters like the CH-47 or Mi-26, or transport aircraft like a C-130 or Y-8. Also, as a modern howitzer system, it possesses a range of engagement of up to 40 km using rocket-assisted projectiles. Because of its greatly reduced weight, the AH4 can be used in mountain warfare, which was traditionally filled by more portable howitzers such as the 76 mm mountain gun M48 or 105 mm OTO Melara Mod 56. Design The body of the system has forward stabilizers as well as spades and dampers. It has a cannon that can fire 155mm/39 calibre shells with an elevation angle from -3° up to 72° with a traverse limit of 22°. The hydro-pneumatic suspensio ...

Howitzer
A howitzer () is a long- ranged weapon, falling between a cannon (also known as an artillery gun in the United States), which fires shells at flat trajectories, and a mortar, which fires at high angles of ascent and descent. Howitzers, like other artillery equipment, are usually organized in a group called a battery. Howitzers, together with long-barreled guns, mortars, and rocket artillery, are the four basic types of modern artillery. Mortars fire at angles of elevation greater than 45°, and are useful for mountain warfare because the projectile could go over obstacles. Cannons fire at low angles of elevation (<45°), and the projectile lands much faster at its target than it would in the case of a mortar. But the cannon is not useful if there is an obstacle like a hill/wall in front of its target.


Etymology

The English word ''howitzer'' comes from the Czech word , from , 'crowd', and is in turn a borrowing from the Middle High German word or (mode ...

155 Mm
155 mm (6.1 in) is a common, NATO-standard, artillery caliber. It is defined in AOP-29 part 1 with reference to STANAG 4425. It is commonly used in field guns, howitzers, and gun-howitzers. Land warfare The caliber originated in France after its defeat in the Franco-Prussian War of 1870–1871, when an artillery committee met on 2 February 1874 to discuss new models for the French fortress and siege artillery, among which there was a piece in the caliber range (later on it became known as the De Bange 155 mm cannon). After several meetings, on 16 April 1874 the committee settled on the 15.5 cm caliber (in the subsequent program-letter of the committee, dating from 21 April 1874, the caliber was for the first time expressed as 155 mm). Since the early 21st century, most NATO armies have adopted 155 mm weapons as an all-purpose standard. They are seen as striking a good compromise between range and power, while only using a single caliber greatly simplifies the logi ...

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 ...

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 ...

Boeing CH-47 Chinook
The Boeing CH-47 Chinook is a tandem rotor helicopter developed by American rotorcraft company Vertol and manufactured by Boeing Vertol. The Chinook is a heavy-lift helicopter that is among the heaviest lifting Western helicopters. Its name, Chinook, is from the Native American Chinook people of Oregon and Washington state. The Chinook was originally designed by Vertol, which had begun work in 1957 on a new tandem-rotor helicopter, designated as the Vertol Model 107 or V-107. Around the same time, the United States Department of the Army announced its intention to replace the piston engine–powered Sikorsky CH-37 Mojave with a new, gas turbine–powered helicopter. During June 1958, the U.S. Army ordered a small number of V-107s from Vertol under the ''YHC-1A'' designation; following testing, it came to be considered by some Army officials to be too heavy for the assault missions and too light for transport purposes. While the YHC-1A would be improved and adopted by the U.S. ...

Mil Mi-26
The Mil Mi-26 (russian: link=no, Миль Ми-26, NATO reporting name: Halo) is a Soviet/Russian heavy transport helicopter. Its product code is ''Izdeliye 90''. Operated by both military and civilian operators, it is the largest and most powerful helicopter to have gone into serial production. Design and development Following the incomplete development of the heavier Mil Mi-12 (prototypes known as Mil V-12) in the early 1970s, work began on a new heavy-lift helicopter, designated as the ''Izdeliye 90'' ("Project 90") and later allocated designation ''Mi-26''. The new design was required to have an empty weight less than half its maximum takeoff weight. The helicopter was designed by Marat Tishchenko, protégé of Mikhail Mil, founder of the OKB-329 design bureau. The Mi-26 was designed to replace earlier Mi-6 and Mi-12 heavy lift helicopters and act as a heavy-lift helicopter for military and civil use, having twice the cabin space and payload of the Mi-6, then the world ...

76 Mm Mountain Gun M48
The 76 mm mountain gun M-48 (AKA the Tito Gun), was developed after the Second World War to meet the requirements of Yugoslav People's Army mountain units, it can also be used as a field gun. Description The first M-48B-1 models may have been Czech M28 mountain guns (bought by Yugoslavia in 1930s) relined from original 75mm calibre to Soviet 76mm (as used on their 76mm regimental and divisional guns), with muzzle-brake added to cope with increased recoil (also Skoda type, borrowed from M.36 AA model). There have been at least five variants of the M48: * The M-48 (B-1) has pneumatic tyres and a maximum towing speed of 60 km/h. It can also be towed by animals in tandem or disassembled into eight pack loads. * The M-48 (B-1A1-I) has the pneumatic tyres and wheels as fitted to the M48 (B-1), plus some of the features of the suspension of the M48 (B-1A2). * The M-48 (B-1A2) can also be used as a field piece but cannot be towed by animals or disassembled for pack transport. * ...

OTO Melara Mod 56
The OTO-Melara Mod 56 is an Italian-made 105 mm pack howitzer built and developed by OTO-Melara. It fires the standard US type M1 ammunition. History The OTO Melara 105 mm Mod 56 began life in the 1950s to meet the requirement for a modern light-weight howitzer that could be used by the Italian Army's '' Alpini'' brigades mountain artillery regiments. That it remained in service with those units a full half century after its introduction is a testament to the gun's quality. The Mod 56 has a number of unique characteristics for a weapon of its caliber, including the ability for its crew to manhandle the gun (due to its light weight), and the capability of being used in the direct fire role. Being a pack howitzer, it is designed to be broken down into 12 parts, each of which can be transported easily. Its ability to be "knocked-down" allows the sections to be transported a number of ways, although the original design was for mule-pack using special pack saddles. More often i ...
