Arjun Main Battle Tank (MBT)

guys can anyone give me links regarding the development of NERA for arjun it will be helpful?

I can same ask about Arjun.

T-90S is good tank, but as in any normal country that is designing weapon systems, Russians want better and better weapon systems, this is normal. Look at US, they also have great tanks and they still upgrade them to even better versions.

Without complete redesign I doubt that all weaknesses problems will be solved.

@Damian are you aware about GSQR ???

I am aware but I don't know the details, I will be thankfull for such details.

DRDO readies hybrid armour for tanks
The Tribune, Chandigarh, India - Main News



Hybrid Armour is mainly Nera and other material like fiber glass within sandwich between composite Armour plates which are between RHA plates..

What is the weakness you are talking about?

Lets see what we may see...

it is top secret, but it is General Staff Qualitative Requirement, which put down certain standards in this case for tank. BTW when first GSQR was made that time we had T72 tanks, therefore they made the GSQR for T80 type of tank, then after Pakistani was testing M1A1 tank from USA, IA panicked and issued new GSQR to counter such type of tank, thereafter no GSQR for MBT.

last year new GSQR for FMBT was issued after exit of DGMF, new DGMF is not again reformulating GSQR for FMBT.

This is in plain and simple terms. you can read this but again it does not tell complete story. History of Arjun Tank Development - Frontier India - News, Analysis, Opinion

Placement of main sight in front armor "window", this makes main sight vurnabale to hits in front armor and is weakening front armor. Sight should be placed behind armor and go through turret top armor. Such configurations minimize danger of sight damage due to front armor hits and weak zone in front armor is absent completely.

Other weakness is lack of side turret armor protection over crew compartment, protection there is provided only by simple ~80mm RHA plate and storage boxes, NATO standard in same place is no less than 300mm thick composite armor.

Next weakness is huge gun mantle, gun mantle should be as small as possible.

Hull and turret also should be redesign that hull amunition storage should be minimal, all or almost all ammunition should be stored in isolated ammo magazine with blow off panels in turret bustle, rest of ammunition should be stored in similiar magazine in hull, bets position should be between turret and engine space.

Driver station should be relocated in hull center line, space on both sides of him can be used for storage.

No details about solving design problems and weaknesses like these I pointed out.

I am not going to waste my time trying to educate you, because you can educate a person who does not know but you cant educate a person out of bias and prejudice. Go read before you yap again.

And maybe some arguments? Please only one argument backed up by logic and evidence.

Kunal provided many photos that are good proofs to my arguments.

You don't want to accept reality, fine, thats Your problem.

Here I marked weak zones, this is reposting old arguments but if You don't understand, so I will do it again.



Red color marks side surfaces weak zones.

Side turret surface where crew sits is protected only by thin RHA armor and storage boxes (in NATO tanks this part of side turret surface is protected by no less than 300mm thick composite armor, this is important for turrets with such geometry).

Side hull have standard side skirts configuration (short ballistic skirts protecting front 1/3 of side hull and long non ballistic skirt over rest 2/3 of side hull lenght), however we can see exposed side hull surface where suspension is attached. Please compare this to other modern MBT's.

Such details are seen as unimportant but indeed, they are very important.



Here blue color marks side turret composite armor, red marks side turret RHA only armor.



Side turret storage boxes.



Red marks front turret weak zones, blue makrs side turret composite armor placement.



Hull ammunition storage. As different conflicts proofs that such storage of ammunition is not safe. Even if ammunition is stored in armored bins or containers.



Here ammunition propelant charges were stored in armored bins with extuingiushing liquids, ammunition below turret race ring.



Here ammunition is stored this way:



Ammunition below turret race ring, in hull rear space and in armored containers. As we see nothing helped to prevent explosion.

How ammunition should be stored? In isolated ammunition magazines both in turret bustle and in hull.

Ammunition magazines both in hull and turret bustle should be isolated by RHA bulkhead with ammunition port protected by small sliding blast cover or by big sliding blast doors. Both magazines, in turret and hull should have blow off panels to release gas and energy from firing ammunition outside, far from vehicle and crew.

Before someone say that I don't know what I'm talking about, such person should read more, watch carefully these photos and compare this to other MBT's over world and think 10 times before will answer.

Last time you failed in all counts comparing Sights to German 80s technology, you did not know shit about anything. Discussions are based on facts and not educating you, just make sure you read by yourself before you enter a discussion.

I agree, I was wrong about sights.

But read again what I posted above in my edited post.

And don't talk about my knwoledge about MBT's, my little knowledge at least exist compared to Your non existing knowledge.

@GK,

He is right abt most things he mentioned:
1. Like Sight placement of Arjun from cousin LEOA4
2.Turret Side which is vulnerable in most tanks
3.Turret mantel is big coz IA wanted space inside Arjun for electronic
4.Arjun Ammo is not good as NATO rounds.
5.Chasis frontal Armour have a void zone..

Above all Arjun is India`s 1st tank and made with Army`s directions,Arjun is the most effective tank in IA than any other in IA..

Arjun MK2 is meant to be improved over MK1 and i hope for the best coz it will be the best..

I pointed out what should be improved and redesigned because all real conflicts shows us what design solutions are good and what are bad.

Look at photos of T-xx tanks, Challenger 2 photo, Merkava photo, all of them have ammunition stored in hull in simple rack or so called armored bins/containers, how ends ammo cook off? Turret is separated from hull, tank is completely destroyed.

And no search photos of M1 tanks from Iraq where these tanks were successfully attacked.

Thanks to all ammunition isolated and blow off panels there were no one single accident when ammo cook off ended with turret and hull separation, there were only 4 to 5 tanks with hull and turret separation when turret was lifted from hull by massive IED explosion, not internal ammo cook off.

Compare weak zones size in different tanks, Arjun have one of biggest weak zones.

Compare side turret protection of NATO tanks and Arjun, Arjun turret side protection is comparabale to T-90S, but much more exposed within safe manouvering angles.
