Please go through the thread and read up the article and compare, The article is repeat of an old article posted by in 2013,
Arjun MBT Regiments recently received Presidential citation which is based on performance and regularity of units in combat and peace in both past and present ..
A. Thermal and FCS are made by BEL under license,
B. Tracks and transmission are manufactured by L&T,
C. Few components along the engine are imported,
These are being repeatedly posted in this very thread with sources, This is not T-90 related thread please keep this till Arjun MK1 development and discussion, Their are other threads which suits comparison debates ..
The article correctly points out some significant issues:
1. Piecemeal imports without any long term contracts results in breakdown in supplies.
2. The components are bought without adequate after-sales support. Typical guarantee period is useless (like one year) for long running projects.
3. The breakdowns are in imported components. This issue again highlights the problem with imports - equipment breaks down and not repaired for months and years.
I have said it before and repeating again - T90 is far more maintainable and supportable compared to Arjun. Arjun's biggest flaw is that its powertrain and tracks is imported, and no proper repair facility is set up till date.
