A model of the Arjun MBT at Def Expo 2004. The most significant of all recent developments surrounding the tank was the test firing of the Israeli Laser-Homing-Attack (LAHAT) missile which qualified the tank as a platform for long range ATGMs. The missile is handled by the gunner as a standard round and with a maximum range of ~6 km, exceeds the capabilities of the Reflex system on the T-90S. The Indian Army expects to take delivery of all 124 Arjun units on order, by 2007.

Main Battle Tank, Arjun
Main Battle Tank (MBT) Arjun is a multi-laboratory programme of DRDO with CVRDE as the lead Laboratory. It is a state-of-the-art tank with superior fire power, high mobility, and excellent protection. Twelve Mk 1 prototypes of MBT Arjun have been manufactured and their performance tests have provided satisfactory results. Some of the breakthroughs achieved by CVRDE during the development of MBT Arjun are in Engine, Transmission, Hydropneumatic Suspension, Hull and Turret, and Gun Control System.
Salient Features
Fire Power
The superior armour defeating capability of the indigenously developed Fin Stabilized Armour Piercing Discarding Sabot (FSAPDS) ammunition and 120 mm calibre rifled gun give MBT ARJUN an edge over contemporary world tanks. A computer-controlled integrated fire control system incorporating day-cum-night stabilized sighting system guarantees a very high first round hit probability and reduced reaction time to bring effective fire on targets.
The stabilization system for the main armament, slaved to the sighting equipment in elevation and azimuth, with a high and accurate laying speed, allows fire on the move.
The superior fire power of MBT is based on:
Accurate and fast target acquisition capability during day and night and in all types of weather .
Shortest possible reaction time during combat engagements
Ability to accurately engage targets on move
Capability to destroy all possible enemy armour at maximum battle ranges
Excellent first hit probability
Main Armament
The rifled 120 mm ARJUN gun together with the newly developed super velocity ammunition, can defeat any contemporary armour used in tanks. The electro-slag refined gun steel tube is autofrettaged to withstand higher gas pressures. A thermal jacket prevents irregular temperature distribution on to the tube due to the weather influences.
Secondary Armament
A co-axial 7.62 mm machine gun for anti-personnel and a 12.7 mm machine gun for anti-aircraft and ground targets are provided as secondary weapons.
Gunner's Main Sight
Gunner's Main Sight consists of a day-sight, thermal sight, a laser range finder and a stabilized head common to all the three channels. The common sighting head mirror is stabilized in elevation and azimuth. The day- sight provides dual magnification.
The thermal imager provides night vision facility to the gunner and the commander to observe and engage target in total darkness and in the presence of smoke, dust, haze and light camouflage. Integral with the main sight is the laser range finder by which targets can be ranged accurately.
Panoramic Sight for Commander
Commander's panoramic sight enables the commander to effect an all round surveillance in the battlefield without removing his eyes from the sight and without being disturbed by the turret motion. The field of view is stabilized with the help of a two axes rate gyro-mounted on the platform of the head mirror. The sight offers dual magnification.
Ammunition
Two types of ammunition, viz, FSAPDS and HESH have been developed for this armament. The highly lethal
FSAPDS ammunition which is the main battle ammunition of the tank has accounted itself admirably during the trails. In addition, the anti-helicopter round to combat the air threat to armour is also under development.
Mobility
Low ground pressure, high power-to-weight ratio and new design concepts in transmission suspension and
running gear result in highly mobile and agile weapon platform.
The remarkable mobility of MBT which also adds to its protection is the result of:
High performance engine
Robust and effective transmission system particularly flexible hydropneumatic suspension .
Optimized running gear with its high shock energy absorption.
Due to the high power-to-weight ratio and low specific ground pressure, MBT is fast, highly manoeuvrable and extremely mobile to cross the most difficult terrain with ease. High acceleration rapid braking capabilities with excellent steering characteristics make MBT agile in the battlefield. Adequate fuel storage capacity and relatively low fuel consumption allow for an optimal operational range.
An important criterion for the mobility of any AFV is the effective performance of the driver. Excellent vision systems both for day and night provide most effective means of observation in all battlefield conditions. The need to keep the crew's fatigue including that of driver at the minimum level over long periods of continuous operation, have been taken care of.
Protection
All round protection from anti-tank ammunition is achieved by t~e newly developed KANCHAN armour to a degree much higher than available in present generation tanks. The high degree of immunity is achieved by.
The computerised design and simulation
A fabricated turret housing lightweight compact KANCHAN armour
Careful dimensioning of wall through optimal slopes and angles
A low silhouette
Crew Comfort
Ergonometry, using anthropometric data of Indian troops, has been kept in view while designing the fighting and driving compartments to fully exploit the outstanding features of the weapon system. Hydropneumatic suspension provides excellent ride comfort for crew eliminating fatigue even on the extended runs.

LA INDIA LISTA PARA REALIZAR PRUEBA DE LANZAMIENTO DEL MISIL AGNI-III.
Categoria: Ejercito - 19-05-2006 16:23
El prestigioso misil balístico de alcance medio de la India, Agni-III, capaz de golpear un objetivo a más de 4.000 kilómetros se encuentra técnicamente listo para el lanzamiento, según informaron fuentes de la defensa. El Agni-III superficie-superficie de capacidad nuclear con propulsor sólido y líquido nunca se ha lanzado y las pruebas se han postergado en varias ocasiones desde noviembre de 2004. Mientras que algunos dicen que el misil tiene un alcance superior a los 3000 kilómetros, otros dicen que su alcance varía entre 4000 y 6000 kilómetros. Puede ser desplegado a través de vehículos móviles de lanzamiento en camiones o trenes y tiene un sistema de dirección inercial con capacidad terminal óptica o de radar mejorada. Fuentes del DRDO dijeron que posee un alto grado de exactitud con una carga nuclear útil media a grande, muy probablemente una cabeza de guerra de 200 a 300 kilos. También se ha alcanzado un escalón importante en la fabricación de los sistemas de comando y control de otros misiles sofisticados superficie-superficie. Según las fuentes, la organización DRDO ha desarrollado capacidad e independencia completa en el campo de la propulsión sólida. La India había previsto estimativamente que el misil balístico Agni-III comenzará a experimentar las pruebas en el 2003. Fuentes de DRDO dijeron que algunos problemas técnicos que habían demorado la prueba ahora estaban bajo control. Los otros misiles, Agni-I (700-800 kilómetros de alcance) y Agni-II (2000 kilómetros)ya han sido instalados en el ejército como parte del arsenal del país.
La fuerza de un Ejercito no está en sus armas, sino en el coraje y valor de sus hombres
