Ramses II MBT
The Ramses II tank is a heavily modernized T-55 main battle tank designed for and used by the Egyptian Armed Forces. A single T-54 was sent to the United States for upgrading. A primary prototype was sent to Egypt where extensive trials were completed in late 1987. The tank finally entered production in 2004–2005. A total of 425 units have been produced. The tank was originally called the T-54E ("E" stands for "Egyptian"). At early stages, the upgrade was concerned with the firepower and mobility of the tank solely, while latter stages included the improvement of the level of protection as well. The tank's hull was modified to accommodate the new engine which had a great commonality with the one used by the M60A3 (the most numerous main battle tank in active Egyptian service), as a result an additional road wheel was added. The tank is armed with the same main gun used by Egyptian M60A3's; in addition to a sophisticated fire control system. History of development In November 1 ...

Main Battle Tank
A main battle tank (MBT), also known as a battle tank or universal tank, is a tank that fills the role of armor-protected direct fire and maneuver in many modern armies. Cold War-era development of more powerful engines, better suspension systems and lighter-weight composite armor allowed the design of a tank that had the firepower of a super-heavy tank, the armor protection of a heavy tank, and the mobility of a light tank, in a package with the weight of a medium tank. Through the 1960s and 1970s, the MBT replaced almost all other types of tanks, leaving only some specialist roles to be filled by lighter designs or other types of armored fighting vehicles. Main battle tanks are a key component of modern armies.#House1984, House (1984), ''Toward Combined Arms Warfare: A Survey of 20th-Century Tactics, Doctrine, and Organization'' Modern MBTs seldom operate alone, as they are organized into armoured units that include the support of infantry, who may accompany the tanks in inf ...

Laser Rangefinder
A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender. Due to the high speed of light, this technique is not appropriate for high precision sub-millimeter measurements, where triangulation and other techniques are often used. Pulse The pulse may be coded to reduce the chance that the rangefinder can be jammed. It is possible to use Doppler effect techniques to judge whether the object is moving towards or away from the rangefinder, and if so, how fast. Precision The precision of the instrument is determined by the rise or fall time of the laser pulse and the speed of the receiver. One that uses very sharp laser pulses and has a very fast detector can rang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M60-2000 Main Battle Tank
The General Dynamics Land Systems (GDLS) M60-2000 or 120S was an upgrade of the M60 tank. The development of the M60-2000 was initiated primarily due to the large number of M60 main battle tanks in service with many Middle Eastern nations unable to afford a sufficient force of more modern main battle tanks. The upgrade was marketed at those M60 users with the industrial capability to convert the tanks themselves. The M60-2000/120S was a GDLS supplied conversion kit that married the turret of the M1A1 variant of the M1 Abrams to the M60A1 hull of the M60, offering many features of the M1A1 Abrams to existing M60 users at a reduced cost. Development It was first referred to the M60-2000 Program and design work began in late 1999 by General Dynamics Land Systems as a private venture for the export market and was never evaluated for US military service. Later the M60 designation was dropped because of the extensive changes and to highlight this as a new vehicle to potential customers t ...

Type 69 Tank
The Type 69 () and Type 79 () are Chinese second generation main battle tanks. Both were developments of the Type 59 medium tank (a locally produced Soviet T-54A) with technologies derived from T-62. They were the first indigenously developed main battle tanks by China, although also classified as medium tanks while in development and service. Their lineage from the T-54A can be seen through the distinct gap between the first and second road wheels. Other improvements included a new engine, ballistic computers, and laser rangefinders. The more advanced Type 79 variant was equipped with a 105 mm rifled gun which was also found on the Type 80 tank. History Development of the Type 69 After the Sino-Soviet split, the Soviet Union withdrew its technical staff and support to China's arms industry. This caused China's domestic tank development to stagnate significantly. Sometime after 1960, the PLA tank corps and Fifth Ministry of Machine Building embarked on the development o ...

Type 59G(BD) Durjoy
The Type 59 Durjoy is a highly modernized version of the Chinese Type 59 tank for the Bangladesh Army. The Bangladesh Army's old Type 59 tanks were upgraded similarly to Type 59G standard at ''902 Central Workshop'' of the Bangladesh Machine Tools Factory with Chinese assistance. Bangladesh Army renamed the tank as Durjoy ( bn, দুর্জয়). History Bangladesh is an active delta with hundreds of rivers and swamps, so its army needs armoured vehicles with limited weight but good protection, firepower and speed. Between the 1980s and the early 2000s, the army had hundreds of Type 59 tanks which stayed in service until 2015. The Bangladesh Army decided to upgrade all the remaining functional tanks because the rebuilding process of a tank costs one third of buying a new one. During this process only the hull of the original tank is used and all the other aspects are upgraded. BMTF upgraded 174 type 59 tanks to Durjoy standard.

Al-Zarrar
The Al-Zarrar (Urdu: الضرار), is a third generation main battle tank (MBT), currently in the services of the Pakistan Army since 2004. The tank is named after Muslim warrior Zarrar bin Al-Azwar. It is a highly upgraded version of Pakistan's ageing Chinese Type 59 tanks (a design that in turn was based on the Soviet T-54A from the mid-1950s), developed with Ukrainian assistance and manufactured by the Heavy Industries Taxila (HIT) – the hub of Pakistani tanks and tracked vehicles, featuring a 125 mm smoothbore gun as primary weapon. The Al-Zarrar can achieve a maximum speed of per hour, weighs around 44 tons and has a four-man crew: commander, gunner, loader and driver.Al-Zarrar tank is a modified version of Tank T-59 GlobalSecurity.org website, Retrieved 2 Octob ...

TR-85
The TR-85 is a third-generation main battle tank designed for the armed forces of Romania. Based on the TR-77-580, the TR-85 tank was developed from 1978 to 1985 and produced from 1986 until 1990. A modernization program was initiated in March 1994 to upgrade the TR-85 tanks to NATO standards. The result was the TR-85M1 Bizonul ("Bison") main battle tank, currently the most modern tank in service with the Romanian Land Forces. Although a further development of the T-55, the TR-85M1 uses a T-block powerpack (similar to the one used in the Leopard 1) based on a V8 German diesel engine, an improved turret, a locally-designed "Ciclop" fire control system (with cross-wind sensor, laser rangefinder and night vision), new 100 mm BM-412 Sg armour-piercing fin-stabilized discarding sabot (APFSDS-T) projectiles and a fully redesigned suspension with 6 road wheels on each side, protected by metal side skirts. Combat weight is 50 tons. Predecessor: TR-580 After the Warsaw Pact inva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grenade Launcher
A grenade launcher is a weapon that fires a specially-designed large-caliber projectile, often with an explosive, smoke or gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary grenade cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organisation by military forces. Grenade launchers can either come in the form of standalone weapons (either single-shot or repeating) or attachments mounted to a parent firearm, usually a rifle. Larger crew-served automatic grenade launchers such as the Mk 19 are mounted on tripods or vehicles. Some armored fighting vehicles also mount fixed arrays of short range, single-shot grenade launchers as a means of defense. History Early precursors The earliest devices which could be referred to as grenade launchers were slings, which could be used to throw early ''grenado'' fuse bombs. The a ...

Overpressure (CBRN Protection)
An overpressure protection system is one designed to protect an individual or group of individuals in a chemical, biological, radiological and nuclear (CBRN) environment. The two parts of the system are a safe area which as far as possible is sealed from possible contaminated air and an air filtration system which will filter out all possible toxins. Air pumps force clean air through the filters into the safe area such that the air pressure within the safe area will always be higher than that outside of the safe area. This pressure differential means that any flows of air will always be from the safe area to the outside, preventing the ingress of toxins. The safe area may be as small as a protective hood for an individual, to a full body hazmat suit, to a fallout shelter or warship. Most modern armoured fighting vehicles will have such a system with the safe area being the crew and passenger compartments, these systems being first adopted to protect against poison gas attack.

Image Intensifier
An image intensifier or image intensifier tube is a vacuum tube device for increasing the intensity of available light in an optical system to allow use under low-light conditions, such as at night, to facilitate visual imaging of low-light processes, such as fluorescence of materials in X-rays or gamma rays (X-ray image intensifier), or for conversion of non-visible light sources, such as near-infrared or short wave infrared to visible. They operate by converting photons of light into electrons, amplifying the electrons (usually with a microchannel plate), and then converting the amplified electrons back into photons for viewing. They are used in devices such as night-vision goggles. Introduction Image intensifier tubes (IITs) are optoelectronic devices that allow many devices, such as night vision devices and medical imaging devices, to function. They convert low levels of light from various wavelengths into visible quantities of light at a single wavelength. Operation Image ...

Night-vision Device
A night-vision device (NVD), also known as a night optical/observation device (NOD), night-vision goggle (NVG), is an optoelectronic device that allows visualization of images in low levels of light, improving the user's night vision. The device enhances ambient visible light and converts near-infrared light into visible light which can be seen by the user; this is known as I2 ( image intensification). By comparison, viewing of infrared thermal radiation is referred to as thermal imaging and operates in a different section of the infrared spectrum. A night vision device usually consists of an image intensifier tube, a protective housing, and may have some type of mounting system. Many NVDs also include a protective sacrificial lens, mounted over the front lens (ie. objective lens) on NVDs to protect the latter from damage by environmental hazards and some can incorporate [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
D-10 Tank Gun
The D-10 is a Soviet 100 mm tank gun developed in late World War II. It originally equipped the SU-100 tank destroyers and was later selected for the T-55 tank, equipping these as late as 1979. On the T-55 the D-10 continues to be in active service in many countries. History At the beginning of 1944, the T-34 tank's F-34 76.2 mm tank gun was replaced by a more powerful 85 mm gun. This rendered the year-old SU-85 tank destroyer effectively obsolescent, since its D-5T 85 mm gun was now also fielded by a more flexible medium tank. F. F. Petrov's Design Bureau at Artillery Factory No. 9 was assigned the task of producing a 100 mm anti-tank gun that could be used on the SU-85 chassis, for the proposed SU-100. To achieve this goal, Petrov's team modified the S-34 naval gun for use in an armoured fighting vehicle. The D-10 is a high-velocity gun of 100 mm calibre (bore diameter), with a barrel length of 53.5 calibres. A muzzle velocity of 895 m/s ...
