Arjun-II MBT development l Updates & discussion.

[Water Car Engineer]

these are in house upgrades or kits from Russia ?

Inhouse, it is branch off from the ERAs developed for the Arjun Mark 2.

More of the upgraded T72

A bunch of T72s are about to look very similar to the T90s around.

They are already pretty much the same thing.

It is getting an uprated 1000hp engine. No numbers yet, but if we use the previous upgrade, I am sure many are getting the refit.

Either its getting a brand new 1000hp Engine (maybe polish) or modified and Uprated one ?

Not new, uprated engine from 780hp to 1000hp.

Plus, there are weight reduction done with new materials replacing old ones.

Example --

A lot of what's being done is branches offs from the Arjun mark 2 experience.


The new added ERA layout is the same weight as the older layout.

MKII looks awesome

What is the present scenario About Arjun's weight reduction process?

Heard they managed 3 tons off, wait and see.

 

[Papa Dragon]

What is the current weight of MkII and how much would it go down to after the modifications?

68 tons, IA recently right in the middle of trials said they want a weight reduction to 55 ton, which is completely unreasonably, considering they also want new ERA, new electronics, APU, mine plough, etc, etc. DRDO says it can do only 3-5 tons at best.

Lighter high-nitrogen steel will be used instead of RHA. An all electric turret stabilisation and traverse systems will replace existing electro-hydraulic system. Aluminium road wheels and ventilators will be used. Some manufacturing practices as well in it's construction, assembly will reduce some weight as well.

Looks like IA is gonna kill this project too in favor of Russian tanks for kickbacks and commissions.

What @watercarengineer has mention is couple of months old news and that this has already been implemented and production has started!

Jindal SHL to make high-nitrogen steel for Defence sector

NEW DELHI: Stainless steel maker Jindal Stainless (Hisar) Ltd. has entered into an agreement with Defence Research & Development Organisation under which the government agency will transfer technology to manufacture high nitrogen steel for the defence sector to the company.

The deal comes after decade-long joint efforts in research and development by JSHL and Defence Metallurgical Research Laboratory, the DRDO’s research wing, to develop the material.

“The transfer of breakthrough technology paves the way for development of equipment-specific application of high nitrogen steel (HNS) in the context of the army’s ongoing and futuristic programmes,” Abhyuday Jindal, vice chairman of JSHL, told reporters in the city on Wednesday.

The technology transfer will boost the government’s ‘Make in India’ programme, Minister of State for Defence Subhash Bhamre said. The DRDO works under the Department of Defence Research and Development of th ..

High nitrogen steel is corrosion-resistant, has better holistic capabilities and mechanical properties and is better than the material imported now, Jindal added.

“We want to be a strategic partner, work with PSUs, work with private industries, to supply this strategic raw material. That is our strength, we want to focus on it," Jindal told ET.

JSHL is working to produce additional variants of HNS with enhanced blast and ballistic protection to cater to niche requirements of the Indian defence sector. The potential applications of HNS include combat platforms like futuristic infantry combat vehicles, mine-protected vehicles, army bridges and army corridors.

bribe them and they will do witj 168 ton.

a local production even if not upto mark can help economy in big way. make extra plans around it instead of making strategy and get product. lets make our stratrgy around our products. but india hai yahan sab golmaal hai.

But I don't think HNS can still bring the weight down to 55tons from 68tons as prescribed by the army. Only way this can happen is if Indian private defense players start bribing IA officials who are involved in the procurement process

 

[X_Killer]

Even if , DRDO will reduce it upto 60ton than it will be more than fine.
Further reduction in weight will increase the maneuverability but it will lower don its stability while firing its main gun
