Vijayanta - Main Battle Tank 4150184
The ''Vijayanta'' (en: "Victorious") was a main battle tank built in India based on a licensed design of the Vickers MBT, Vickers Mk.1. The Vijayanta was the first indigenous tank of the Indian Army. The prototype was completed in 1963 and the tank entered service on December 29, 1965. The first 90 vehicles were built by Vickers in the UK. Production continued at the Heavy Vehicles Factory in Avadi until 1983 with 2,200 being built. History The Vijayanta was first made in the UK before production moved to India. Indian production got underway, allowing UK production to cease. The Vijayanta was to be phased out by the Indian Army by 2008 (the decision to phase out 296 "pre Mark 1A tanks" was already taken in 1997). In 1997 the plan to repower the Vijayanta was shelved. The overhauling of the fleet was discontinued from the year 1999–2000 as the withdrawal from service of the Vijayanta had already been approved. Bulk production of Vijayanta spares ended in 1989.

CVRDE
Combat Vehicles Research and Development Establishment (CVRDE) is a laboratory of the Defence Research and Development Organisation (DRDO). Located at Avadi, in Chennai, India. It is the main DRDO lab involved in the development of Armoured fighting vehicles, Tanks, Automotive electronics and many other. History After the Independence of India, the Chief Inspectorate of Mechanical Transport Establishment (MTE), which was previously located in Chaklala, Pakistan, was moved to Ahmednagar.

Armoured Vehicle-launched Bridge
An armoured vehicle-launched bridge (AVLB) is a combat support vehicle, sometimes regarded as a subtype of military engineering vehicle, designed to assist militaries in rapidly deploying tanks and other armoured fighting vehicles across gap-type obstacles, such as (and primarily) rivers. The AVLB is usually a tracked vehicle converted from a tank chassis to carry a folding metal bridge instead of weapons. The AVLB's job is to allow armoured or infantry units to cross craters, anti-tank ditches, blown bridges, railroad cuts, canals, rivers and ravines), when a river too deep for vehicles to wade through is reached, and no bridge is conveniently located (or sufficiently sturdy, a substantial concern when moving 60-ton tanks). The bridge layer unfolds and launches its cargo, providing a ready-made bridge across the obstacle in only minutes. Once the span has been put in place, the AVLB vehicle detaches from the bridge, and moves aside to allow traffic to pass. Once all of the ve ...

130 Mm Towed Field Gun M1954 (M-46)
The 130 mm towed field gun M-46 (russian: 130-мм пушка M-46) is a manually loaded, towed 130 mm artillery piece, manufactured in the Soviet Union in the 1950s. It was first observed by the west in 1954. For many years, the M-46 was one of the longest range artillery pieces around, with a range of more than (unassisted) and (assisted). Design history The order was given in April 1946 to design a "duplex" artillery pice to replace the obsolete 122 mm gun M1931/37 (A-19), 152 mm howitzer-gun M1937 (ML-20) and other World War II era field guns, such as 122 mm Model 1931, 152 mm Model 1910/30, 152 mm Model 1935 (BR-2). The new pieces, designed by the Motovilikha Plants, factory No 172 (MOTZ), shared the same carriage and were given the designators M-46 (130 mm) and M-47 (152 mm). The respective GRAU designators are 52-P-482 and 52-P-547. The development phase was finished in 1950 and one year later series production started. Many M-46s were ...

Self-propelled Artillery
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 ...

M-46 Catapult
The M-46 Catapult was a self-propelled gun developed in India by Combat Vehicles Research & Development Establishment of the Defence Research & Development Organisation. Description The turret-less vehicle has an open area in the centre for the gun and crew but retains the driver's position and includes a horizontal metal shield for overhead protection. To withstand higher firing stresses and to cater for longer recoil the Vijayanta tank's hull has been elongated with seven bogie wheel stations on either side. The stability to the vehicle during firing is provided by unique hydraulic suspension locking system. The self-propelled medium artillery gun can fire both HE and AP ammunition and has a maximum range of 27 km. The gun has a limited static traverse 12½% on either side and an elevation of +45% to -2%. The system can stow 30 rounds of separate loading ammunition. Retired in 16 March 2021. Development After the 1965 and 1971 wars between India and Pakistan, the Army ...

Barr And Stroud
Barr & Stroud Limited was a pioneering Glasgow optical engineering firm. They played a leading role in the development of modern optics, including rangefinders, for the Royal Navy and for other branches of British Armed Forces during the 20th century. There was a non-military arm of the company which made medical equipment, like photocoagulators and electronic filters, some of which were used by the BBC. The company and its intellectual property passed through Pilkington group to Thales Optronics. The Barr and Stroud name was sold on to an importer of optical equipment, who use the trademarked name for a line of binoculars and similar instruments. History Archibald Barr and William Stroud had been associated from as early as 1888 when the two men were professors of, respectively, engineering and physics at the Yorkshire College (now the University of Leeds). In 1891, they were approached by the Admiralty to submit a design for a short-base rangefinder for trial. By this time, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arjun (tank)
The Arjun () is a third generation main battle tank developed by the Combat Vehicles Research and Development Establishment (CVRDE) of the Defence Research and Development Organisation (DRDO), for the Indian Army. The tank is named after Arjuna, the archer prince who is the main protagonist of the Indian epic poem ''Mahabharata''. Design work began in 1986 and was finished in 1996. The Arjun main battle tank entered service with the Indian Army in 2004. The 43rd Armoured Regiment, formed in 2009, was the first regiment to receive the Arjun. The Arjun features a 120 mm rifled main gun with indigenously developed armour-piercing fin-stabilized discarding-sabot ammunition, one PKT 7.62 mm coaxial machine gun and a NSVT 12.7 mm machine gun. Powered by a single MTU multi-fuel diesel engine rated at 1,400 hp, it can achieve a maximum speed of and a cross-country speed of . It has a four-man crew: commander, gunner, loader and driver.

Composite Armour
Composite armour is a type of vehicle armour consisting of layers of different material such as metals, plastics, ceramics or air. Most composite armours are lighter than their all-metal equivalent, but instead occupy a larger volume for the same resistance to penetration. It is possible to design composite armour stronger, lighter and less voluminous than traditional armour, but the cost is often prohibitively high, restricting its use to especially vulnerable parts of a vehicle. Its primary purpose is to help defeat high-explosive anti-tank (HEAT) projectiles. HEAT had posed a serious threat to armoured vehicles since its introduction in World War II. Lightweight and small, HEAT projectiles could nevertheless penetrate hundreds of millimetres of the most resistant steel armours. The capability of most materials for defeating HEAT follows the "density law", which states that the penetration of shaped charge jets is proportional to the square root of the shaped charge liner dens ...
