Arjun Mk.II : News and Discussions
The Arjun Mk.2 is an improved version of the original Arjun main battle tank. It was developed in cooperation with Israeli defense companies. A total of 13 major improvements were made. After prolonged development the original Arjun entered service with the Indian Army in 2004, however it failed to impress the Army and improvements were required in order to make it combat-worthy. The new Arjun Mk.2 has improved protection, firepower and mobility over it's predecessor. Trials of the Arjun Mk.2 began in 2012. Series production is expected to begin a couple of years later. It should replace the ageing Cold War era T-55 and T-72M main battle tanks in service with the Indian Army.
The Arjun Mk.2 has some design similarities with the German Leopard 2A5 main battle tank. It is claimed that weight of this main battle tank was reduced from 59 to about 55 tones comparing with it's predecessor in order to improve operational and logistic mobility.
Hull and turret of the Arjun Mk.2 were redesigned. Protection was improved by adding locally-developed explosive reactive armor modules. It seems that the new ERA is based on the Russian Kontakt-5 technology, developed in the 1980s and used on the T-90 and some other Soviet/Russian tanks. Armor modules counter APFSDS and HEAT rounds, as well as RPG rounds. Ready to use ammunition is stored in the turret bustle with blow-out panels.
This new main battle tank is armed with a fully-stabilized 120-mm rifled gun, which is loaded manually. A rifled gun of such caliber is used only on the British Challenger 2 MBT. This gun is very accurate at long range. The Arjun Mk.2 is compatible with Israeli LAHAT anti-tank guided missiles. Missiles are launched in the same manner as ordinary projectiles.
Secondary armament consists of coaxial 7.62-mm machine gun and a roof-mounted remotely controlled weapon station, armed with a 12.7-mm heavy machine gun.
This new main battle tank is fitted with advanced thermal imaging and panoramic sights, that give it a hunter-killer capability. Fire control system of the new tank should have a hit probability over 90%, when firing on the move. The new tank also has improved communication systems.
This new Indian tank has a crew of four, including commander, gunner, loader and driver.
The Arjun Mk.2 is fitted with a new unspecified turbocharged diesel engine, which replaces the previous German MTU MB 838 Ka-501 diesel unit, developing 1 400 hp. It is speculated that the new engine is the Cummins QSK-38 turbocharged diesel unit, developing about 1 500 hp. It should be coupled with a French transmission. Also Ukrainian manufacturer proposes for this tank a new 6TD-5 turbocharged diesel engine, developing 1 800 hp. The Arjun Mk.2 is also fitted with auxiliary power unit which powers all systems when the main engine is turned off. This MBT can be also fitted with a mine plough.
阿琼MK.2型配备一款新的不明涡轮增压柴油发动机，取代以前的德国MTU MB 838 KA-501型柴油发动机，输出功率1400马力。据推测，新的发动机是康明斯QSK-38涡轮增压柴油发动机，输出功率1500马力，与之匹配的还有法国传动装置。乌克兰制造商为该新型坦克提供了一款新的6TD-5涡轮增压柴油发动机输出功率1800马力。阿琼MK.2型还装备了辅助电源可以在主发动机关闭的时候为整个系统提供动力，这款主战坦克也装备了扫雷犁。

So all the 93 improvements (required by Army) are incorporated now? I read an article some months back that said over 50 improvements have been made.

Improvements or no improvements...........no more orders will be placed. We use imported products.

The Arjun Mk-2 will weigh around 67 tonnes and this fatally limits the tank’s operational effectiveness for the Indian Army.
The tank is too heavy to be deployed across the border with Pakistan. It is unable to effectively traverse terrain filled with natural and/or artificial obstacles. Or areas criss-crossed with rivers and canals. That rules out most places in Rajasthan, Punjab and the mountainous terrain of the J&K sector.
This has forced the army to identify areas where the Arjun can safely be deployed and its operational units based. This probably means the Arjun will not fight alongside the T-90s and T-72s. It will certainly not be part of the Indian Army’s strike corps formations, as it could get bogged down in unfamiliar terrain. This runs counter to the philosophy of armoured formations, which are designed for mobile offensive operations deep inside enemy territory. Unlike the T series tanks that have been airlifted to high altitudes like Leh and even out of the country, the Arjun cannot be airlifted by the IL-76 and C-130 J transports of the Indian Air Force (IAF). The C-17 Globemaster to be inducted by the Indian Air Force (IAF) has a maximum payload of 75 tonnes — insufficient to airlift the 67 tonne Arjun Mk-2 with attendant support equipment.
这迫使军队只能根据安全部署和运输来确定能使用阿琼的地方。也就意味着阿琼不会与T-90和T-72S一同并肩作战，肯定不会编入印度军队的攻击部队，因为它可能陷入不熟悉的地形。这就与装甲部队专门为了在敌方领土深处移动作战的理念背道而驰了。不像T系列坦克可以被空运到高海拔地区的Leh甚至走出国门，阿琼不能用印空军的伊尔-76和C-130J运输机空运。印空军 C-17全球霸王最大有效载荷为75吨 – 可以空运不足67吨的阿琼MK-2，但运载工具数量不够。

Even if Arjun iS 67tons heavy its ground pressure is low....

UPA doesn't care. They're looking for a new scam to do. They know 2014 is their end. So using full use of the last opportunities.

Any new news about Arjun mk2??? What are the major advantage over t90s .and its not only UPA the Indian army is stucked with t 90

Whoa, great news, hope IA inducts Arjun MK.2 in large no:s.
T-90 is grossly inferior to Arjun on almost all grounds.
But Arjun costs very high compared to T-90 which is relatively cheap.
