I guess they are doing drills, One Arjun toeing another Arjun..

Pathetic camo to use in desert !!

Agreed..

DRDO should try Digital camo on armored vehicles..

Can anyone provide details on India indigenous engine to be fitted into Arjun Mark - II?

Can anyone provide details on India indigenous engine to be fitted into Arjun Mark - II?

It is know that the engine is 1500hp..

 

[bengalraider]

Can anyone provide details on India indigenous engine to be fitted into Arjun Mark - II?

Judging from the MTU effort i would say the engine would have to be a multi-fuel V-12 power plant with computer controlled fuel injection and twin turbochargers, if we follow the MTU example much of the engine with the exception of the cylinders and pistons would be made from lighter materials such as titanium and where possible(keeping wear and tear in mind) aluminium as well.
P.s find below a picture of the MTU engine at last years DEFEXPO

in 2007 this news appeared

Homegrown Tank Engine Project Begins

"It is proposed to take up a project on Development of 1500 HP Engine in the XI Five Year Plan. Preliminary Design Work has already commenced."

This was the testimony provided by the Defence Ministry on behalf of DRDO to the Parliamentary Standing Committee on Defence for its fourteenth report, tabled in March this year and was in response to questions on the MBT Arjun programme. And, according to this piece in DefenseNews, work has begun.

The 1400 HP engine manufactured by MTU Friedrichshafen GmbH (photo ©Copyright MTU) will power the first 124 Arjun tanks, though the Combat Vehicles R&D Establishment has, according to the DefenseNews report, floated a "domestic and global expression of interest (EoI)" on October 31 for the co-development of a "1,500-horsepower Compact High Specific Power Output Diesel Engine". Officials at the laboratory had alluded to this when I was at Avadi for the Arjun MBT special report a few weeks ago, so it's finally now in motion.

This is good news. The MTU powerpack, coupled with the gunner's main sight (GMS) and tracks account for 58 per cent of the cost of a single Arjun tank. It seems reasonable to assume that MTU itself will offer to build the 1,500HP engine with DRDO, though there will of course be other, possibly more efficient, competitors.

Here's what the MoD had to say in March to the House Panel on Defence about manufacturing tank powerpacks in India: "Suitable indigenous power Packs are not available for application in MBT. Indigenous production of power pack through license production is feasible with enhanced production order for MBT Arjun considering the economy of scale. A project for developmentof indigenous power pack is planned in XI Five Year Plan."

Not much headway has been made on an indigenous GMS -- an indigenous laser range finder, day sight, thermal imager and fire control computer won't be part of the Arjun until beyond the hopeful second batch order. Here's what the MoD had to say about it: "There are few vendors in the world who can manufacture gunner's main sight. DRDO is developing indigenous gunner's main sight. It is likely to mature and be available beyond 124 tanks."

And finally, the tracks -- when I was at Avadi, I got the picture about why we're still importing tracks: the indigenously made rubber-coated metal pins that hold the indigenous track links together couldn't withstand the friction. The rubber would fray quickly allowing the pin's metal to come into contact with the track's metal, thereby quickly distorting it and resulting in a mobility breakdown. Since DRDO is still developing resistant rubber for those pins, we're importing the entire track assembly. Shouldn't take long though -- the CVRDE has apparently asked for this technology as well from some specialist agencies abroad. And this is what the MoD said in March: "Indigenoustrack is in advanced stage of development. It will be available for Arjun production tanks beyond 124 Nos."

Will post here in detail shortly on the Army's GSQR 2020, on its requirement of a supertank already expressed to the CVRDE. Oh, and have a chilled out Diwali if you're into that sort of thing

can anyone say what is the hybrid armour which the drdo has reportedly manufactured?also what is the weight of arjun's turrer?how much weight can be shred if it is replaced with an unmanned turret similar to what oman has done challenger 2 mbt.

well all the things you have asked are top secret, BTW drdo dont manufacture it only develop.

Hybrid Armour is simply multilayer laminate (composite) armor with additional dynamic protection like under Armour ERA, NERA etc.

20 ton is the weight of Arjun turret..

Unmanned Turret helps to reduce lots of weight with is upto 13tons if we used over present Arjun, Anders turret is better than Falcon turret..

An Israeli view on the Arjun MK II

I found this while surfing another defence forum. I am unable to give you any source since no source of this was provided there. It seems the guy who wrote this is in some way associated with the Arjun project....

#1 Arjun is getting massive Israeli help and NOT 6 as being reported in many places in media, but 8 rolled out recently. There are some Armour and rifling techniques which Isreal has taken from India as they were truly impressive. Other than that a lot of contribution from Israel. NO I CAN NOTprove this right now.


This is what i know after discussing Arjun with a high ranking scientist who is a member of the Foreign defense services board (rough translation from Hebrew) who have worked on Arjun for the last 9 months. I personally witnessed a really cool addition to the recent 8, it employs the exact same copy of the HW and SW as the Abrams self diagnostic system...not only does it tell you when the tank is not feeling well but also tells you which part.

there is also a battle management system deployed....the funniest part was how decked up the CO's Arjun was...the seats are amazing, even the Russian contingent (overpaid pricks) were emotionally moved to see the interior with all the widgets - and went the best capitalist tank (being sarc. and all)

...i think i will be able to SOMEDAY get pictures of the ARJUN M2 and let you folks see what i have seen...it a true comfort to drive that tank
I walk among diffrent circles compared to many out here on the forum and intend to build a reputation where people believe me without much fuss...

as i will not always be able to post links (actually i am too deep into defense to rely on media and links to prove myself). Anyway i am off to a hunting trip organised my some army chaps here in India..will defanately take pictures and post that


#2 You really will have a problem ...say in a desert coming close to this machine. This is a really good machine...the main gun beats the Merkava any day.

Bloody hell the shear energy at extended range in ft.lb delivered with the accuracy is truly astonishing...i personally think this main gun is a accidental find for Indian's. the saboy round penetrated the hull of a t-55 derelict then went through the second one behind it and the place where it pierced the sand dune had a formation of glass crystals around the sand.

I have an idea (to how the Pakistanis can get it)...when the crew falls to sleep driving this beast - due to its crew comfort...you could run to it and shove some tnt between the hull and the chaise

#3 I just saw the interior picture of Al khaled. You have a serious problem here. Is that a prototype or the finished product? I am serious , i really need to know this.

I truly hope that it is not a finished product. If it is, my god " the very Question that arjune is a better tank is a understatement. You have no idea what you have here lads. Even if the idea is a "will get the job done and cheap to produce" Al Khaled can be mass produced is the idea of Pakistani Armour....etc etc....WHAT ARE YOU GUYS THINKING?

Someone here tell me what is the purpose of Al-k...isit supposed to take on the inferior Indian tanks and put the t-80 against the arjun (still crazy - Russian admit it will eat the t-90) ok maybe its a attempt by Pakistan to atleast get hold of technologies to create a tank..etc etc
the nuts and bolts in alkhalid will kill the crew if a HESH round even nicked it. moreso the LR-APFSDS will cut like butter the armour....you guys better get some good reactive armour on this tiny thing. please any experts here..
i really wish to ask some questions on the al-khaled.

#4 Incidentally my father worked on a series of Merkava tanks (yes yes i am a Jew) i too graduated with honors in Armour. but right now in a slightly different objective in India. anyway i agree with you maneuver is imp.

BUT THEN AGAIN in all the discussion i have seen here maneuver is something gone a miss here. i havent driven a al -k but this arjun is as maneuverable as a Abram M2(spent a lot of my time with these tanks) ..no bloody difference, i dont know maybe al-khalid is much better compared to A-M2 in maneuver.

You will outrange it...by what 5000m from a reflexes Chinese copy of soviet projectile...do you think no one here thought of ATGM and countermeasure. This is the classified bit in electronics Israeli gave to Arjun. I am telling you buddy, someone better get serious about countering Arjun...its mere prototype passed direct hits from t-90 AP rounds (new round), it passed fragmented top attack munitions, You want to kill it.

a) you need to get it tracks off
b) in some way get the electronics off
c) hit it at less than 200 m from something like a Milan 3 repeatedly in hopefully the same area or
d)put a huge mine under it (has counter electronic to detect it...direct contribution from what is to be a Merkava 4 system)
e) i would have a serious debate going against this tank on a Merkava 3 and i am honors in armour and spent a few.

I think the brits will be very very interested in the armour these people have developed or even the rednecks....thats the level and quality you are looking at/

BE, this is known to us for very long time before 2008, plus Denil was member of earlier IDF, he gave great insight into arjun tank. BTW he was the one who shown Trophy being tested on Arjun, but that pic was lost.

Thanks saya. i was not aware of that. seems i am kind of behind time here.

 

[p2prada]

There is a lot of Israeli stuff on Arjun. So it's obvious Israel has been in the project since some time.

Also a lot of the Isreali stuff will be replaced by Indian stuff on the Mk2, for the process of indigenization.

 

[shuvo@y2k10]

this is a great news.i would really like to know how the merkava 4 fares compares to the arjun in all important tank parameters like armour,firepower etc.
may be the indian army reads this posts and gets some enlightment like gautam buddha.can't weight for arjun mk2-with indegeneous engine,era and total 93 upgrades.it might be a super-tank by 2015.by the way drdo may also try trophy system,new 120mm apam tank round developed by israel,and also a better shaped turret with top armour like merkava-4.the army must cancel the fmbt project altogether and concentrate on future arjuns.

 

[nitesh]

What Israelis components are there? I am sorry but I don't know which is referred here

we need at least 500 Arjun Mark - II. The Arjun Mark - II will be more than enough to meet the immediate threat in our surrounding. We also need to increase the Tank count in our army to around 6000 units.

sanction tanks are 3800 as per report of standing committee on defence, BTW we can have 200 light tanks for chines border.
