Why doesn't India mass produce Arjun tanks?
為什麼印度不大量生產阿瓊坦克？

Although DRDO has developed two versions of Main Battle Tank Arjun - Mk I and Mk II, its main potential user Indian Army is far from satisfied with them. They have ordered only 242 Arjuns - 124 MK I and 118 MK II against DRDO's request for a minimum 500 orders. So, for whom will India mass produce the tanks? Let the army place larger orders.
雖然印度國防研究發展組織已經研發出了兩款阿瓊主戰坦克，分別是 Mk I 和 Mk II
然而，潛在的主要用戶印度陸軍對這些阿瓊坦克相當不滿意，只訂購了242輛阿瓊坦克，其中124輛MKI，118輛MK II，而印度國防研究發展組織要求最少訂購500輛。
如果大量生產阿瓊坦克，賣給誰呢？還是讓印度陸軍多買一些吧

Mass produce for what????
Arjun is not a Bajaj Pulser or even a Mercedes.
Builing a tank is complicated and hell lot expensive than the costliest commercial veh.
Idea of mass production is when there is a demand of that sort.
Mass production involves production in lakhs.
World’s largest army PLA (China) has about 8000 tanks.
So now do you think there is a demand for Arjun of that sort to even invest for mass production.
Even India doesn't require that many tank pieces.
Now take your call.
大量生產，賣給誰？
阿瓊坦克不是奔馳車啊
造一輛坦克的工藝是複雜的，比最貴的商用車貴多了
是否大量生產，這要看是否有需求
大規模生產的話，那就是幾十萬輛。
世界最大陸軍解放軍有8000輛坦克。
你覺得阿瓊坦克的需求有那麼多嗎，有必要大規模生產嗎？
就連印度都不需要那麼多坦克。

The Indian Army has procured around 250 Arjun MK1 and 120 MK2, but these numbers are not on par with the number of T-90 and T-72, both around 3000, ordered from Russia.

印度陸軍採購了大約250輛阿瓊MK1坦克和120輛阿瓊MK2坦克，沒有印度從俄羅斯買的T-90和T72坦克多。
Arjun MK1
Arjun MK1 was inducted into service in 2004. Arjun MK2 was designed with a total of 73 improvement over MK1. But this led to increase in weight of MK2 by over 6 tonnes. Due to this excess weight, the MK2 can only be operated in semi-arid or desert area of West India. It cannot operate with its full potential in urban warfare, heavily forested area and mountainous terrians. The weight of MK2 also restricts itself to be airlift to North East Frontier against China. It cannot be transported via Air or Rail in large numbers, which is a major tactical disadvantage. Moreover, India have poor road infrastructure along North East Frontier with China.
阿瓊MK1坦克
阿瓊MK1坦克是2004年服役的。阿瓊MK2坦克是對MK1坦克經過73項改進而成的。
不過MK2坦克也因此增重6噸。
也正因如此，阿瓊MK2坦克只能在印度西部的沙漠地區機動，不能在城市、森林和山地中發揮全部性能。
增重後的MK2也無法用直升機空運至東北對付中國。
無法大批量通過空運和鐵路運輸進行機動，這是一大戰術上的劣勢。
況且，印度東北靠近中國地區的路況差。
Arjun MK2
Since Army now has demanded to reduce the weight of MK2, DRDO will have to redesigned its turret and hull and will have to use new composite materials. After all these improvements are introduced in MK2, Army will conduct trials for the tank. All this will take about 4-6 years.
阿瓊MK2坦克
印度陸軍已經要求對阿瓊MK2坦克進行減重。為此，印度國防研究發展組織重新設計了炮塔和外殼，將採用新的複合材料。
MK2坦克經過改進後，印度陸軍將對其進行試驗。而這一過程大約要4-6年。
Further, to add salt to the injuries, Arjun MK1 is not in service since 2013 because of unavailability of spare parts. Mk1 imports almost 70% of its components from foreign vendors. Due delays in deals with these vendors, Arjun MK1 fleet is grounded and not going to be revived any time sooner.
更糟糕的而是，2013年以來，阿瓊MK1坦克因為缺少零部件而一直沒有服役。
MK1坦克70%的零件是從國外進口的！
組建阿瓊MK1坦克團的計劃也隨之擱置。
The main reasons behind the unsuccessful induction of Arjun is the continuous changing of requirements from the Army for the MBT. Due to this it took more time for the DRDO to design the tank, with new specifications given by the army every time the tank reaches trials. Other major reason is failure to increase the indigenous production of spare parts for the tank. Indian Defense Ministry failed to sign deals with foreign vendors to provide spare parts and components for the MBT. Arjun MBT remains one of the many indigenous defense products, which failed to find a significant place in the force.
阿瓊坦克沒有成功服役的主要原因是，印度陸軍對主站坦克的要求不停地改變。
印度國防研究發展組織只好不停地更改設計，結果是耗費大量時間。
另一個主要原因是坦克的零件未能大量國產化。
印度國防部沒有和外國供應商籤署提供零件的協議。
阿瓊坦克是印度許許多多未能在軍隊佔據一席之地的國產裝備之一。
