TANKS
1. The Arjun MBT is developed by DRDO and built by Central Vehicle Research and Design Establishment (CVRDE) at the Heavy Vehicles Factory at Avadi. It weighs 59 tons, and powered by a 1400bhp MTU Ka 401 turbo charged diesel engine. The Arjun has a range of 450 Km and a 120mm rifled gun. It is protected by the indigenously developed Kanchan Class explosive reactive armour, and has a top speed of 72 Kph. It can fire APFSDS, LAHAT, HE, HEAT and HESH rounds. Additionally, it is armed with a 12.7mm AA machine gun and a 7.62mm coaxial machine gun.
2. This Ajeya is another example of technological co-operation between India and the erstwhile USSR. The Ajeya is based on the T72M, and is armed with a new 125mm 2A46M gun. The Ajeya MKII features upgraded Polish SKO-1T DRAWA-T fire control systems and thermal imagers, laser illumination warning system, DRDO Explosive Reactive Armour, a new GPS system, improved crew protection, a new 1000bhp PZL-WOLA engine and banks of 6 smoke grenade-launchers on each side. The plan is to reequip 1,500 Ajeya's MKII with updated technology.
3. The T72 was perhaps the world's most advanced battle tank design when introduced in the 70's. The T72 is extremely lightweight, at 41 tonnes, and very small compared to Western MBTs. The army used the T72 tank to ravaging effect in the 1971 war. A 780bhp V12 diesel engine powers it. It is armed with a 125mm smoothbore main gun capable of firing anti-tank guided missiles, as well as standard ammunition, including HEAT and APFSDS rounds, a 7.62mm machine gun and a 12.7mm anti-aircraft gun. It has a range of 460 km and a top speed of 60 Kph.
4. The Bhishma is the Indian version of the T90. A 1000bhp Chelyabinsk diesel engine powers it. Standard protective measures include a blend of steel, composite armour, smoke mortars, Kontakt-5 explosive-reactive armour, & laser warning receivers, Nakidka camouflage and Shtora infrared ATGM jamming system. Weighing 52-tons, it is armed with a 125mm smoothbore gun that can also fire ATGMs. The auxiliary armament consists of a 12.7mm Kord HMG and a 7.62mm pintle mounted machine gun. India operates 2011 T90 and Bhishma tanks.
5. The Tank-EX is a technology demonstrator that has been designed and built wholly by DRDO and CVRDE. It weighs 53 tons, and features top-secret composite armour technology. It is armed with the Arjun's 120mm main gun, a LAHAT anti-tank guided missile tube, a 12.7mm anti-aircraft machine gun, and a 7.62mm coaxial machine gun. It has the same 1000bhp diesel engine that is used on the T72M. It has a max speed of 60kph and maximum range of 480Km.
ARTILLERY
1. The Carrier Mortar Tracked self-propelled mortar system is based on the Sarath with also has amphibious capabilities. It has an 81mm mortar mounted on a modified troop compartment and carries totally 108 mortar rounds. It is powered by a 300bhp engine, has a maximum speed of 65kph on road, 7Kph submerged and max range of 240Km. It can be operated by all mechanized infantry battalions providing instantaneous fire support, and also provide protection to the crew.
2. The Bhim self-propelled howitzer and is designed as a purpose built self-propelled artillery vehicle. Weighing 60 tons, it has a firing range of 52Km. It has a 14.5mm welded steel armour, and is armed with a Denel 155mm L52GS howitzer. It can carry 50 rounds and is powered by a 1400bhp Ka-501 engine that gives it a top speed of 60Kph and a max range of 450Km. It has a fully automatic ammunition loading system, as well as a turret-mounted auxiliary power unit.
3. The Pinaka is a Multiple Barrel Rocket Launcher (MBRL) artillery system. Each launcher consists of 12 rockets and can be operated in manual, automatic tergetting or remote controlled mode. The rockets have a range of 60Km. Pinaka saw service during the Kargil War, where it was successful in neutralizing enemy positions on the mountain tops. The launcher is mounted on a Tatra Kolos truck, it has a maximum combat range of 120Km and a maximum speed of 80Kph.
4. The BM-30 Smerch (Russian for Tornado) is the precursor to Pinaka MBRL. It entered service in the Soviet Army in 1989. After the collapse of the Soviet Union, a number of these MBRL's were sold to India. A 525bhp 12-cylinder diesel engine powers it, due to which it has a top speed of 60Kph and a maximum range of 850Km. The 300mm rockets have a range of 90Km.
