Nobody answered my earlier query a few weeks back about testing of Dhanush artillery gun. The final test stalled because a faulty (made in china) muzzle brake was passed on as German made. It either broke itself or cracked the barrel - whatever.

No information has been posted on the current state of the testing and replacement of the muzzle break.

The more knowledgeable member, please take a crack at the available information.
Muzzle brake has nothing to do with faulty bearing mesh. You don't have a bearing mesh or roller bearing in muzzle for that.
Moreover the case was not because of the accident/ incident. It was a case of fraud which has been registered. Field tests has nothing to do with it and the accident occurred because of faulty ammo or manufacturing defect rather then duplicate roller bearing.

Review: Ashok Leyland Super Stallion FAT 6x6






Have I reached the wrong place?
No. Unless you were searching for something else on the Internet that, er, we don’t offer, and somehow ended up here.

I mean, what’s this massive machine?
This massive machine is Ashok Leyland’s Super Stallion FAT (Field Artillery Tractor) 6x6.

That’s a handful.
It may seem so. But the name is rather self-explanatory. It’s a towing vehicle for artillery with 6x6 traction. Artillery in this case meaning weapons like the Bofors gun.

Heavy. But must be a beast of an engine.
Literally. Six litres, six cylinders, 450 horsepower.

Hey, that’s not much.
In hindsight, you are right. A Grand Cherokee SRT has a bigger engine and makes more horses.

So what’s so beastly in the engine?
The torque. The FAT 6x6 makes 1400Nm of it.

Wow. That’s a lot of pulling power.
That’s not all. It makes this 1400Nm of pulling power with the engine spinning at just 1300rpm. We bet you aren’t going to get a passenger car that makes more power or torque than its engine revolutions.

Incredible. This must make this FAT 6x6 quite a scorcher…
It does. But ‘scorcher’ here is quite not the ‘scorcher’ you expect it.

In the sense?

Don’t expect 0-100 times. The FAT 6x6 runs out of breath at 90kph. But speed is not the ware the gun carrier peddles.

Isn’t it useful to get around the battlefield, er, fast?
Not as much as getting around as such. But what all it can get around and over of.

You mean, like different terrain?
Of course. And boy, can this thing tackle terrain. In fact, not only terrain. It can withstand a lot of torture.

Oh, is it bullet proof?
No it doesn’t need to be. The FAT 6x6 doesn’t actually have to get into the line of fire. It’s a carrier for long range guns. So it mostly sees duty besides the gun as they fire into the distance. But the challenge is always getting the gun to the strategic spot which may involve climbing something steep, fording something deep, or just going over terrain the limbed wouldn’t walk over.

So, can the FAT 6x6 tackle terrain?
Oh, you bet. In fact, we did not know terrain like this existed before we tackled them in this military monster.

Terrain like what?
Firstly, Leyland’s research and development centre has a variety of torture tracks… surfaces that thoroughly wring the suspension inside out. There are massive rumblers, boulders, potholes, and the one surface that will leave your bones rattling even after you are done tackling it.

What’s that?
What Leyland calls a pave way. Think of it as a cobbled-stoned street multiplied by 50. All Leyland vehicles go through this intense torture test for 24 hours at a stretch. Drivers take 45 minutes shifts each.

Is the pave way that tough?
I was inside the truck for about 15 minutes for photos and by the time I got out, 15 felt like 50 minutes and I had a quick check if my bones will still where they were supposed to be. This little shake-up or shake-down rather was like being inside a consistent earthquake.

What are its other talents?

The FAT 6x6 can climb up a 25 degree incline. Now, I have been on rather steep off-road jaunts. Even if not on such steep ones. Yet, I am familiar with the feeling of having all of my food at the back of my intestines as I drive up something steep and have that unnerving sight of nothing-but-sky out of my windshield. But despite all off-road tech available to modern passenger cars, one thing was unavoidable.

Momentum?
That’s right. I’d always have to reverse a distance and build up some speed before having any hope of making it up and over.

So even the FAT 6x6 would need some?
Oh no. The FAT groans its way to the foot of the incline, comes to a complete halt, and on an incline so steep that humans can’t walk up or down without support, this machine roars its way up like a Tata Nano goes up the ramp of a multi-storey car park. It needs to be in the lowest gear, and makes some noises when grunting up, but the 6x6 goes up in one clean move. It goes around and does the climb again. Again. And again.

Must be that torque.

How right you are. I repeat. 1400Nm at 1300rpm-1500rpm, in case you missed it.

Did you drive it?

As I don’t have a commercial vehicle license I wasn’t entrusted with challenges like negotiating inclines, tackling torture tracks and driving over surfaces that test the articulation of this beast that stands a good 400mm off the ground. But I did drive it over a normal surface.

And?
Putting it in first was an issue at first. I used to shove the gear stick with maximum force. But just figured all it needed was a firm, short push. As the six-cylinder engine redlined at a mere 2500rpm, it meant quick gear changes for quick progress. It was only by sixth gear in that nine-speed manual gearbox that I could feel the vehicle making any swift progress. In Army duties, I reckon this Stallion will mostly be sticking to the first four gears. Shifting gears in this thing wasn’t exactly a breeze. I am not in a position to comment on heavy vehicle ergonomics, but with all the even gear ratios, second, fourth, sixth… your arm does have to reach out to the rear to get a firm grip for that firm shove. The steering is is light and makes the vehicle easy to manoeuvre around curves.

Does it handle and brake well?
Braking takes some getting used to. If you are gentle, the behemoth takes a while to shave off speed. If you stomp on the brakes, this juggernaut comes to an immediate, unnerving halt. Surely, being smooth with this thing takes some practise. Reversing isn’t much of a problem thanks to a reverse camera. In fact, you can’t exactly call it a reverse cam as it’s primarily meant for the driver to load, unload and tow the gun at the rear. Besides, the reverse screen doesn’t get activated when you engage reverse gear. It remains on permanently.

Wow a reversing cam. Any other comfort features?
Noisy, but powerful air-conditioning with intense heating and cooling. The FAT 6x6 is, after all, designed to operate at -40 deg to 55 deg Celsius.

What about the tyres? They are usually the weak link in a tough vehicle.

In the FAT 6x6, the tyres are tougher than the vehicle itself. It has a centralised tyre inflation and deflation system. The driver can increase and reduce the tyre pressure from inside the cabin depending on the terrain the FAT 6x6 needs to tackle. Besides, the tyres – all six of the obviously – are locked to the rim. So even if there’s a severe puncture that takes the tyres to zero psi, the rubber remains on the rim ensuring the 6x6 never has to scrape the terrain with its wheels and the driver retains better control of the entire vehicle.

Incredible this thing is.

Quite. Rather than a war machine that destructs, the Super Stallion is a machine that protects and endures. For something this side of a tank, it can take quite a beating.

What is the maximum range of our artillery we have in our arsenal because chinese had artillery ranges from 100-400km.

Artillery can never have 100km+ range unless it is a rocket propelled artillery shell. If one could do such a big artillery, then people wouldn't be building missiles. The barrel of the artillery is made of metal and that imposes certain restrictions regarding pressures. If the pressure is beyond a certain point, it will burst. If the metal has to bear such large pressure, then the quantity of metal would make it so heavy that it will be completely immobile and even difficult to reload.

Iraq had tried to make a satellite launching artillery called project babylon but could not be completed due to assassination of the Canadian engineer who was building it in 1990, possibly by Mossad.

Take a read at this link on project babylon:

The maximum range of our artillery is 42km with no rocket propelled shells. The maximum range of pinaka rockets is 65km.

So, artillery = fucking thing
Hmm.....

Artillery fire means cannon launched bullets. Now, cannon launched rocket makes little sense as it is better to use MRBL. Even the cannon uses charges to blast the shell. Instead of that charge, use it as rocket propulsion fuel to launch rockets.

You are forgetting that the error range of guided rocket is minimum radius of 1% of firing range. Sometimes it is 1.5% too. So, for 100km distance, the rocket will fall in a circle of 1km around the intended point. If it is unguided rocket, it will be 2% or more.

You want 100km artillery? Huh!

Can you please name the Chinese artillery systems with over 100km range?

The reason artillery is used is because it is cheap and can be fired in thousands per hour with very little expense. It just needs a metal shell and some charges, both are kept separately from each other and hence are very simple to mass manufacture.

Artillery is not a pinpoint accurate gun. The philosophy of artillery is: QUANTITY HAS ITS OWN QUALITY.

Using expensive shells like rocket based shells is very foolish. In terms of effectiveness, MRBL pinaka is far better than artillery per round fired. But pinaka is significantly expensive than artillery and hence is not used as much.

Rockets are meant for salvo fire to destroy a limited area which is being occupied by enemy forces while artillery is used as a barrage fire to prevent enemy mobility, not to destroy enemy position

Oh! artillery means just cannon launched bullets right...then why we are calling just artillery divisions/regiments.....why not with two different names like cannon artillery regiments and mbrl regiments.

There is nothing like 400km range artillery in chinese arsenal. Neither cannon, nor tube artillery. 500 km range is for there short range tactical missile.
My bad they had 300km range artillery

Are you trying to tell me that pinakas are considered to be artillery?

Let's just agree that just the word "artillery" by itself standalone means tube launched explosive containers without any propulsion beyond the tube. Since the container has to minimize drag, it's made aerodynamic and elongated. Special meaning is when extra words are added to the base word. "Rocket artillery" is throwing explosive containers that are propelled by a rocket. The projectile needs space for rocket fuel and needs to be aerodynamic, so it's a long tube with pointed nose and fins to stop the tube from tumbling. If you have a spaceship in orbit around a planet and it uses it's gun to bombard the surface then it's an orbital artillery bombardment. The projectile guidance is a separate matter, whether it's a unguided ballistic trajectory, or manuverable using aerodynamic control surfaces or vectored thrust. There. It's all just semantics.

200 km..... Weishi rockets are always shrouded in mystery. You can't simply term them as Rocket Artillery due to their warhead. These are more of tactical guided and unguided missiles. But anyway what matters is how and under what command they are deployed.
