What's new

Completed Arjun Mark 2 At The Republic Day Parade

. . . .
Modifications.

1. Missile firing capability
2. Commander’s TI panoramic sight Mk II
3. Driver’s uncooled thermal imaging night sight
4. Additional ammunition (don’t ask… won’t tell!)
5. Enhanced ammunition penetrator
6. Effective alternative to muzzle reference sight (MRS)
7. Resin-based CCC
8. Ten-round containerised bin
9. Explosive reactive armour panels
10. Infra-red/Thermal imaging resistant paint
11. Air defence weapon remote firing
12. ALWCS (advanced laser warning and countermeasure system)
13. Roof mounted driver’s seat
14. ATT in GMS (gunner’s main sight)
15. Advanced land navigation system
16. New final drive with increased reduction ratio
17. Advanced running gear system
18. New track system
19. Mine plough

In addition, there are 74 “minor” improvements (adding up to 93 improvements in all) that are not really that minor. For example:

1. An improved sprocket wheel that modifies the manufacturing process from rolled homogenous armour (which required gas cutting and machining) to a forged sprocket which is 50% the cost, 50% easier to build and gives a longer life.

2. Another minor modification is the incorporation of stainless steel fuel tanks. The painting required for the insides of the earlier mild steel tanks was creating residue that clogged the fuel lines and filters. But stainless steel requires no painting.

3. Internal electrical wiring has been comprehensively re-laid, incorporating the dozens of modifications that have been incrementally carried out over the years. The wiring has now been laid systematically, making it easier to track and repair.

4. The radio harness has been modified, and internal communications are now digital. That makes it easier to integrate audio alarms and provides an SMS facility between the crew (how ‘bout sum chai?). It is totally noise free… now the crew can communicate easily.

5. Another improvement is the incorporation of a new compact Auxillary Power Unit (APU), which provides 8 KW of electrical power (uprated from the existing 4.5 KW APU). This requirement is based on fresh load budgeting calculations, allowing the tank to operate in “silent mode” with the additional electronics… also keeping a cushion for future electronic enhancements.

Of these 93 modifications, 45 have already been tested during trials in summer 2011… having been incorporated on one "improved Arjun Mk I" tank. A second tank is being cut open to put in three major modifications, including the commander’s panoramic sight Mk II.

Broadsword: Upcoming modifications on the Arjun Mark II


The Arjun Mark II features an enhanced version of the Arjun's well-proven hydro-pneumatic suspension, with the new one designed for a 70-tonne load. This is part of an improved "running gear", including the road wheel mountings, the road wheels, axle arms and shock absorbers.

The new suspension has already been tested in the recent trials and run for 1,300 kilometers. In order to obtain an accurate comparison with the earlier suspension, the trial tank was fitted with both: the old suspension on the left side and the new one on the right. The photographs --- in which the new suspension still looks new while the old suspension looks somewhat the worst for wear (not surprising; 1,300 km is a lot of running!) --- point to a successful upgrade.

The Arjun's suspension will be practically all-Indian. The road wheels, which continue to be built by Sundaram Industries, have been improved with better manufacturing and bonding processes for the rubber. Tractor Engineeers Ltd (TENGL), an L&T company, is doing parallel development of the Arjun track (imported so far), including development of one of the most difficult running gear technologies: the track pins.

Broadsword: Improving the Arjun's already great suspension

I think its the radar. But what use it is on a ground vehicle ??

Can't be radar, too exposed. This type of place is reserved for the smoke grenades but from what I can see on the other side, they're way at the back. My experience extends solely to Pakistani operated Armour, so we'll need an Indian Armour boy to clarify. Though it could be a tandem placement of smoke grenades to manage angles, the cover could then be a hatch.

It is a millimetre band radar system operating as a Missile Approach Warning System (MAWS) and also has a Radar Warning Receiver (RWR) and radar jammer.

Why dont they move the laser warning counter measure system to the right? And the gunner sight up like in the older protoypes?

Man the older prototype looks really ugly.What's with the bent cannon.
As for moving gunner's sight that will be done in mk3.Couldn't do it as structural modification in mk2 would compromise schedule and time table.

It's not bent, the paper isnt flat.

This here is also another prototype from way back when.

What is this thing ???? doesn't look like the Armour panels on the right side :what:

from press release ..

Arjun Mark II incorporates enhanced firepower with Automated Target Tracking and greater variety of ammunition including “Gun‐fired anti‐tank missile” and the devastating “Thermo‐baric ammunition”; enhanced protection that include Explosive Reactive Armor”, “Laser Warning cum Countermeasure System”, a “Mine Plough”, a “Remotely operable Anti‐Aircraft weapon”, “a Roof mounted driving seat”; “Advanced Land Navigation System” and “Enhanced night vision capabilities”. The swift development of Arjun Mark II is a testimony to the skills and capabilities of India’s DRDO scientists, technicians and maturity of industry.
