I think you can update the same engine of 1500hp to 1800hp without doing too much change.
Yes, but not for that you need a ready 1500hp engine to base it on.
Again, as much as I hate saying this, there's only drawings of the 1500hp as of now... Not even prototypes.

That's why
Arjun Mark1A is running with a 1400hp relic that's older than HM Ambassador.
In this forum only ashok leyland tractor which won the army tender is capable of 563 horsepower was shown.
Exactly... Around 500hp is the limit for existing private Indian tech,rest is imported. Max being new Tata Prima (1040hp). There's no Ashok-Leyland 1500hp engine.

But they can definitely do , cant they???? Uptill now there wasnt any need for them to go for 1500HP , GOI didnt ask them or provided any incentive. Somebody has to start somewhere right.

They can, but they probably won't. Not for a order of few hundreds. Not even if they're getting into armoured-vehicle building. Kalyani/Mahindra/Tata may develop engines for IFV or APC soon, but 1500-1800 is far away!

DRDO may team up with them, but none of them will be of much help I'm afraid.
And time is of the essence. We don't have one right now and existing Arjun is running with decades old 1400hp, which isn't acceptable. Thus my Tejas AESA example... to use an imported one, until ours is ready to replace it.

Same reason drones see limited use in conventional battlefield. A whole tank regiment will be under the risk of being taken out, if the enemy manages to jam the datalink of command signals.

DRDO unmanned tank will only ever do reconnaissance, rescue & recovery.
I wasn't thinking of unmanned/remotely controlled tanks, but the men being situated *outside* the main tank body, perched on some contraption, like a pole, that keeps them a few feet away. From this position outside the tank and a few feet away, can they still drive the tank, and do all things as though they were sitting inside it? I dont see any reason why they cannot.

Now if they make the main body light, and provide strong localized protection just around the men on the perch, I think this will solve the weight problem. Now, if a missile hits the tank, in the current design, the men are toast. However, in the new design (if feasible), the men may escape the blast from the missile...

Goofy design??

That's very very very very unlikely, given they'd have to completely redesign a whole new platform& drastically reduce the volume... or build it with plastic.

The 1800hp engine target indicates that it's probably 60t. Now, that's doable.
They have been redesigning the hull and turret already. 50ton statement is from reliance and reported by Hindu .

1800 hp is something I read somewhere else so maybe not that authentic.

I think they misquoted 60t... A 50t tank won't need 1800hp engine.

Unless the completely start redesigning afresh from scratch, noone can reduce a 65t behemoth to 50t.

Don't connect 1800hp with 50t weight . Reliance never talked about 1800hp engine it's different rumor.

Still you maybe right . But based on army's preference for t90 type weight they might redesign it completely.

Why doesn't even Arjun mk1a have mantlet that protects the area where the gun joins with the turret...

Are you sure you ain't confused about what a gun-mantlet is? Arjun actually has a bit too much mantlet. T-90 doesn't have one.

Challenger 1 (no mantlet)
Challenger 2 (with mantlet)

I don't know much about tanks but this one was on quora.

.........................................................

The Arjun MKI & II are both very disappointing vehicles, with significantly reduced capabilities compared to other modern third and fourth generation MBTs.

Let´s start with mobility:

The Arjun MkI is powered by a German MTU MB 838 Ka-501 diesel engine. This engine is a modernized version of the MTU MB 838 CaM 500 multi-fuel engine that was first fitted to the Leopard 1 MBT in 1965. Thanks to various upgrades, and the addition of a supercharger, the Ka-501 can reach 1400 hp while the CaM 500 can only reach 800 hp.

So fans of the Arjun MBT (and its manufacturer) would have you believe that this tank has excellent mobility thanks to a hp/weight ratio of 23,5 (slightly below average for a modern MBT but still within acceptable norms).

However, raw engine power is only one of the factors that determines a tank´s mobility. The problem is that because of its outdated design, the Ka-501 engine is big, heavy, extremely fuel inefficient (a pitiful 200km range on good terrain while other MBTs can easily reach 500 km) and has very poor performance in terms of rpm and torque. These problems are worsened by the vehicles heavy weight (58 tons for the MkI and 68 for the MkII, the heaviest MBT in the world), meaning that the Arjun struggles to crest even a slight hill.


Big, heavy, and terrible fuel efficiency...

The current version of the MkII still uses the same outdated, crappy engine, although there are plans to upgrade to a modern American Cummins engine coupled with a French suspension. So far, these plans have yet to materialize.



Protection:

On paper, the Arjun´s armor is supposedly quite good. On paper.

The manufacturer of the Arjun MBT claims that its "Kanchan heavy composite armor" is on par to the British Chobham armor from which it was developed. The Arjun MkI&II can also use locally manufactured ERA blocks, said to equal the performance of Russian Kontact-5 ERA from which they were developed as well.

So theoretically, the Arjun´s armor uses excellent materials. The problem here is the design of the armor itself.

The arjun´s gun shield is significantly thinner than other modern MBTs. In addition, the primary gunner sight does not have a extra armor module.


Notice how the left side of the turret is completely bereft of any composite armor (those white layers on the other side of the turret front). The gunner sits behind 250mm of spaced steel armor, and that´s it. Any modern APFSDS round will cut through that like it´s butter and vaporize the gunner.


Notice the huge weak spot created by the primary gunner sight.

So the turret front is terrible. But the turret sides are even worse.


Notice how the vaunted "Kanchan heavy composite armor" (the white layers of armor) leave 2/3rds of the turret sides exposed. The turret sides of the Arjun I&II are literally paper thin. Worse, contrary to what the manufacturer claims there are no blowout panels on the Arjun MBT, nor is it equipped with a separate ammunition compartment.


Where is that separate ammo compartment you´ve been talking about?

This means that virtually round penetrating the turret will ignite the tank´s ammunition and vaporize it in a big fireball.

Moving on...



Firepower:

If you thought the Arjun was a bad tank before, you haven´seen anything yet.

The Arjun MKI&II both use the same gun: a 120/55 mm rifled gun inspired by the British L30 rifled tank gun used by the British Challenger 2. Proponents of the tanks will tell you that because the gun is rifled, it is more accurate than the smoothbore guns used on the Abrams or the T-90.

That´s bullshit, to put it simple.

A rifled gun applies a spinning motion to the round it fires, meaning those rounds will be more stable when travelling through the air and more accurate over range. However, modern ammunition doesn´t need a rifled barrel to be accurate and stable, since they are equipped with little fins at the end of their penetrator, that apply a spinning motion to the round as it travels through the air. Put simply, modern ammunition spins itself, and doesn´t need a rifled gun to be accurate.


Notice the little fins at the end of the round.

Therefore, the claims that the manufacturer makes about the gun´s accuracy are very doubtful at best. It is claimed that the Arjun has a First Hit Probability (FHP) of 90%, even on the move, thanks to an excellent stabilizing system and Fire Control System (FCS). Comparative trials were conducted between the Arjun MkII and the T-90, where it was claimed that the Arjun MkII outperformed the T-90.

However, Indian Army Generals have since come out to say that those trials were rigged by corrupt defense officials, and that the accuracy of the Arjun MBT is vastly overestimated.

But the worst of all is the penetrating power of the Arjun´s main gun. At 2km, a round fired by the Arjun can only penetrate 300mm of Rolled Homogenous Armour (RHA).


This is pitifully bad. At 2km, this tank won´t even be able to penetrate the side armor of most modern MBTs.

As a comparison, most modern APFSDS rounds can penetrate between 700 and 900 mm of armor at 2 km. That´s 3x the penetration of the Arjun.

The poor penetrating power of the Arjun is attributed to poor materials used for the penetrators, a low-pressure firing chamber and a short penetrator length.



Soooo, if we recap:

The mobility of the Arjun is terrible. Its armor is virtually non-existent with huge weak spots all around the turret, and its gun is horrendously inadequate by modern standards.

There is a reason why even the Indian Army refuses to use the bloody thing. Only 100-200 Arjuns have been ordered to placate the government and DRDO (the Arjun manufacturer), while the Army relies on 1250 T-90 and 2500 T-72 MBTs

Nonsense and baseless. Only an arms merchants trying to sell something else will come up with all these negative points, hence are you paid by arms merchants or only baseless critic?

One of Indian Youtuber countered a video, that was also using the same graphics that is used in this Quora post. The graphic is very wrong. He countered a lot of points of this Quora post. But he didn't say anything about engine.

Although pretty old topic, but one of our guys did a very good rebuttal of this video.

Some of it is true, some of it is bollocks...

It is right about mobility being only raw power, produced by a vintage design fuel-guzzling engine, but can't say about the "very poor performance in terms of rpm and torque"... Maybe true, maybe false.
Arjun's engine is like Ambassador engine compared to modern SUV. Hopefully soon a 1500/1800hp engine will be available.
But mobility wise it's fucking fast & had great acceleration... Range & efficiency is poor.

About armour, that analysis of Mark 1 is highly improbable. Yes the mantlet is too big & can't be more than 50cm, but...
Actually read this post I made only previous pages ahead;
There was a time when Army was looking for any excuse to reject Arjun... And flawed frontal armour layout , would have been a ground to completely get rid of it forever. Yet never had a single bit of bitching have been hard from those whine-queens, about armour atleast. If it really had major weak spots, then that weapon have been hurled everywhere by them.
And compared to T-90 the holes in protection are quite similar.
Comparison with Leopard2 won't work as Arjun is much larger & longer. The blowout panels have also been confirmed to work.

Mark 1A is however kind of a jugaad! The gunner's side clearly does not have any ERA st all. Hope it'll get fixed in the final redesigned Mark 2 turret. Side armour added is jugaad too.

Ammunition really isn't that great. But as of latest reports it can do 500mm+, which is not nearly enough but similar to the mango rounds of T-90S. We'll catch up.

But tanks note it's only target & it can fire HESH, thermobaric, penetration-cum-blast etc. (soon CLGM too.)

As I said earlier, it's the maturity of tech that was gained from Arjun. Its heat-hardened hardware, sensors & sights, FCS, IFF, NERA, Mobile Camouflage & Active Protection systems.

As of that guy, he may sound all analytical but his tone is a of he's roasting the Arjun... Which is never a sign of neutral point of view.
He used quite a bit of old data, from when Arjun was indeed kinda shitty & full of teething issues. During '90s rusky observer were very happy with how badly the Arjun performed. It's sights were malfunctioning & fun could hold an aim.

But times change, just compare the gun stabilisation now:
This was disproved long ago by some senior member in the forum..
Can be done by anybody! Here, just compare the distance of between commander & top of gunner's sight.

Protection of Mark1 & Leopard 2A4 are same (about 800mm) due to the same reason Arjun is unnecessarily heavy... IT'S FREAKIN HUGE!
