Type 74 105 Mm Self-propelled Howitzer
The Type 74 105 mm self-propelled howitzer is only used by Japan. It shares a number of automotive components with the Type 73 Armored Personnel Carrier which was developed during the same time. Komatsu developed the chassis, while the howitzer and turret were designed by Japan Steel Works. The first prototypes were completed in 1969–1970. The howitzer was accepted for service in 1974. It carries 30 rounds on board. It is amphibious when using the erectable flotation screen stowed around the periphery of the upper hull. It is equipped with an NBC filtration system.

Self-propelled Howitzer
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 is ...

M2 Browning Machine Gun
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NATO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V4 Engine
A V4 engine is a four-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration. The V4 engine is less common compared to straight-four engines. However, V4 engines have been used in automobiles, motorcycles, and other applications. Design Most V4 engines have two crankpins that are shared by opposing cylinders. The crankshaft is usually supported by three main bearings. Compared to the more common inline-four engine layout, a V4 engine is much shorter. Although different V angles can be used, if the two pistons are at a 90° V-angle with shared crankpins, the engine offers the additional advantage of perfect primary balance that reduces vibration. The design can also result in a smaller rocking couple than an inline-four engine, and the shorter crankshaft is less susceptible to the effects of torsional vibration due to its increased stiffness. Disadvantages of V4 engines include its design being inherently wider compared to in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torsion Bar
A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process. Usage Torsion bar suspensions are used on combat vehicles and tanks like the T-72, Leopard 1, Leopard 2, M26 Pershing, M18 Hellcat, M48 Patton, M60 Patton and the M1 Abrams (many tanks from World War II used this suspension), and on modern trucks and SUVs from Ford, Chrysler, GM, Mitsubishi, Mazda, Nissan, Isuzu, LuAZ, and Toyota.

Type 73 Armored Personnel Carrier
The is a tracked armored personnel carrier that entered service with Japan Ground Self-Defense Force in 1973. In 1996 the JGSDF adopted the wheeled Type 96 Armored Personnel Carrier to supplement the Type 73. Development The Defense Agency's Technical Research and Development Institution issued a requirement for a new APC to replace the Type 60 APC in 1967. Among the requirements included a maximum speed of over 60 km/h, ability to carry 12 men including the crew, to be fully amphibious, have all-welded aluminium armor, provision for the infantry to use their small arms from inside the vehicle and be armed with a 20 mm cannon, a 12.7 mm machine gun and a 7.62 mm machine gun. An automotive test rig, called the SUT, was built in 1968. Komatsu and Mitsubishi Heavy Industries each built two prototypes the following year, one each in steel and aluminium. Mitsubishi's aluminium model was chosen for use in December 1973. Description The Type 73 is almost uniqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Japan Steel Works
is a steel manufacturer founded in Muroran, Hokkaidō, Japan in 1907. History Japan Steel Works was set up with investment from British firms Vickers, Armstrong Whitworth and Mitsui. During World War II, they manufactured what was then the world's largest gun barrel to be fitted on the battleship ''Yamato''. 200 workers in their main plant in Muroran were killed in a 1945 attack by Allied Forces. Products Japan Steel Works' industrial processes which are used to purify steel are held to high standards. These include the use of argon gas to eliminate impurities, and the addition of manganese, chromium and nickel to make the steel harder. Japan Steel Works' services are in great demand owing to its role as one of only five manufacturers worldwide of the largest single-piece components of Reactor pressure vessels for nuclear reactors at the company's factory, which is located on the island of Hokkaidō.

Hokkaido
is Japan's second largest island and comprises the largest and northernmost prefecture, making up its own region. The Tsugaru Strait separates Hokkaidō from Honshu; the two islands are connected by the undersea railway Seikan Tunnel. The largest city on Hokkaidō is its capital, Sapporo, which is also its only ordinance-designated city. Sakhalin lies about 43 kilometers (26 mi) to the north of Hokkaidō, and to the east and northeast are the Kuril Islands, which are administered by Russia, though the four most southerly are claimed by Japan. Hokkaidō was formerly known as ''Ezo'', ''Yezo'', ''Yeso'', or ''Yesso''. Nussbaum, Louis-Frédéric. (2005). "Hokkaidō" in Although there were Japanese settlers who ruled the southern tip of the island since the 16th century, Hokkaido was considered foreign territory that was inhabited by the indigenous people of the island, known as the Ainu people.

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] |
