Arjun Main Battle Tank (MBT)

[bengalraider]

we have the LAHAT for Arjun . it can be set to top attack mode also.

with one major difference; the LAHAT being a missile is vulnerable to countermeasures by active protection systems like the Trophy and the Arena ; Whereas the KSTAM being a guided shell is not!

The munition is equipped its own guidance and obstacle-avoidance systems for navigation, small millimeter band RADAR and infrared sensors for target identification, and an Explosively Formed Penetrator for attacking targets.

so it can be jammed too ??

Lahat is a laser guided weapon. As soon as a tank's protection system detects, it will deploy its countermeasures throwing up a smokescreen. Laser guidance has severe limitations.

friends what do u think. india should start the new and fresh development of new tank with help of ukraine or any other ex-soviet/isreal/russia contriesas china did with A1KHAID.WE CAN INTEGRATE OUE ELECTRONICS IN THEM.why we are waisting our time on arjun as we know army is not going to take in in lagre numbers.why is goi to shy to admit that arjn has failed.i dont think is going to embrass them.i don think local people pay lot of attention to it.projects do fail.not like pakistan where none of military projects fails.

did you even read the entire thread ARJUN HAS NOT FAILED IN ANY TECHNICAL PARAMETER.it was only due to the cost involved in upgrading the logistics branch of the army for the arjun that it may be capped at 124 (or as some reports indicate 500 units).

They don't admit it, because - it hasn't failed.
Stop comparing our machinery with that of Pakistan. Its an entirely different race out there. Our primary requirement on the road to become a South-Asian superpower is indigenous production. With the end of the cold-war years ago, you cannot expect India to sustain a major conflict depending primarily on foreign weapons.

I think :
1. You need to do a lot of reading.
2. Develop some basic common sense before suggesting our emulation of Pakistan.
3. Look more in terms of what has been achieved, instead of what remains to be perfect.

i know its OT but still how good is the al khalid anyways ??
all i've come across is mixed reviews.
the yankees and russians reject it right away as just another heavily upgraded T 54 or T 72
whereas shiv aroor on livefist in response to a comment said that it is actually a pretty good and advanced tank .
what is the real truth ??

Rifled guns have Rifling done in them . the cross section of a rifled gun looks something like this .

Pros of Rifling.
Increases long rage accuracy as the fired shot revolves on its axis which provides it stability and accuracy.
Cons of rifling:
It reduces speed of the fired shot because a part of the imparted energy is used up in giving the shot spin.
more wear and tear.
costlier to produce.

now
a HESH round needs low energy in order to be most effective as the lower the energy the lesser the area over which the plastic explosive will be scattered and the higher the pressure at the area of impact. if it is fired with too much velocity then the plastic explosive will simple scatter over a large area and the resulting pressure per unit area will simply not be enough to do significant damage i the inner compartment of the tank . Hence a Rifled gun is perfect for a HESH Round. as it provides it a lower required speed and high accuracy

These days Tanks use the much more effective APFSDS round which for simple understanding can be equated to an arrow . the higher the speed the better the penetration hence smooth bore guns on contemporary tanks as they give the rounds higher velocities.

to put things in perspective.
the ideal velocity for a HESH round is 500-600 m /s
where as the ideal velocity for a APFSDS round is 1000-1100 m /s or more

only two countries use rifled guns on their tanks as of today
the challenger in UK
and Arjun in india.

See my Avatar. iam using it for long time. I have uploaded the image in DFI

In final test, Arjun tank to take on Russian T-90

New Delhi, Jan 16 (IANS) The Arjun main battle tank will take on the Russian built T-90 tanks March 1, when the core strength of the indigenously-built tank will be assessed by the Indian Army's observers.


New Delhi, Jan 16 (IANS) The Arjun main battle tank will take on the Russian built T-90 tanks March 1, when the core strength of the indigenously-built tank will be assessed by the Indian Army's observers.

This could deliver the final verdict on a platform that has been 36 years in the making and which has cost the exchequer Rs.3.5 billion ($71.7 million).


With one regiment of the Arjun tanks (comprising 45 tanks) completing their conversion training and field practice, the comparative trials will be conducted at Mahajan Range in Rajasthan March 1.


'Our aim is not to determine a winner in these trials, but to test the core strength of the tanks,' a senior official of the Indian Army said, wishing anonymity.


Experts from mechanised forces and officials from the Defence Research and Development Organisation (DRDO) will also witness the comparative trials.


The DRDO had handed over 16 tanks to the Indian Army last year, completing one regiment of 45 tanks. The regiment was then subjected to conversion training and field practice.


The DRDO's demand for the comparative trials of the two tanks was being seen as a last-ditch bid to save the Arjun as some 500 tanks would need to be acquired by the army to make the project feasible.


The army, however, has made it clear that it will buy no more than the 124 Arjuns it has contracted for because it is unhappy with the tank on various counts. This apart, the army says the Arjun can at best remain in service for five to 10 years while it is looking 20 years ahead and needs a futuristic MBT.


The army's stand has been contrary to a third-party assessment by an internationally reputed tank manufacturer.


The official said: 'As suggested by the army, Arjun tanks were subjected to rigorous trials and assessment in a third-party audit. After the extensive evaluation, the auditor confirmed that Arjun is an excellent tank with very good mobility and firepower characteristics suitable for Indian deserts.'


'They (the auditor) also gave inputs on production procedures for further enhancing the performance of Arjun tanks. DRDO will be incorporating all these inputs before the next lot of 62 tanks is handed over to army by March 2010,' the official added.


The Indian Army laid down its qualitative requirement for the Arjun in 1972. In 1982, it was announced that the prototype was ready for field trials. However, the tank was publicly unveiled for the first time only in 1995.


Arjun was originally meant to be a 40-tonne tank with a 105 mm gun. It has now grown to a 50-tonne tank with a 120 mm gun. The tank was meant to supplement and eventually replace the Soviet-era T-72 MBT that was first inducted in the early 1980s.


However, delays in the Arjun project and Pakistan's decision to purchase the T-80 from Ukraine, prompted India to order 310 T-90s, an upgraded version of the T-72, in 2001.

Finally it is ready for trials, now they can prove the Arjun and cancel some T-72 modernisation.

Armand, it has proved itself. infact army chief himself appreciated and gave the go ahead some time back -

The Hindu News Update Service

they were asking for international audit. that was also done and -

still they back track when it comes to induction. strange and bizarre.

Apparently it was missing something to delay the trials...

fine. if it can be enhanced it should be done. in any case it will happen as time passes due to the demands of the then technology. that is how any system evolves.

but the point is even with what it has, Arjun out runs, out fires t-90, which the army is inducting with many problems.

So Arjun is officially a failure. The research was not feasible with its output.

Arjun tanks to be tested against Russian T-90s before May ​

Saturday, January 16, 2010, 21:53 IST

New Delhi: With the first Arjun tank regiment completing its conversion trials, the Army is readying to test the indigenous MBT's mettle against the proven Russian T-90s in the early half of the year.

"Army is preparing for comparative trials against the Russian T-90s in the early half of this year ... before May," a senior Army officer said on Saturday.

The Army had completed its first regiment's fleet of 40 Arjun MBTs last May when 16 of the Combat Vehicle Research and Development Establishment-built tanks were handed over to it by the Heavy Vehicles Factory in Avadi near Chennai.


However, the Army has placed orders for only 124 Arjuns in all as yet and there have been enough indications that further orders may not come through, as the Army was now looking at a futuristic MBT that could be operational beyond 2020.

It was also felt by the Army's Mechanised Forces circles that Arjuns could serve the Army only for about a decade as the technology and design of the tanks were on the verge of obsolescence already.

Having taken nearly 37 years to have a regiment of the indigenous tanks since the project was approved, the tanks have changed designs from a 40-tonne class vehicle with a 105-mm gun at the conception stage to 50-tonne vehicle with a 201-mm gun during production. (talk about mistypes)

"For such a delay and design changes, Arjun tanks have proved to be a worthy combat vehicle for Indian deserts during the conversion trials and a third-party audit," the officer said.

The Arjun project was approved in 1972 and the first prototype of the tanks was readied in 1982 and publicly displayed in 1995.


However, during its development stages, several structural and design flaws were identified by the DRDO and the Army that were later rectified.

Now that the Army had got delivery of the first 40 tanks to complete its first of the three regiments that would operate Arjuns, the indigenous MBT is likely to be put through comparative summer trials against the 45-tonne T-90s between March and May this year.

Meant to come as replacements for the aging T-72 MBTs of Russian origin, the mainstay of Indian combat vehicle fleet since the 1980s, the delay in Arjun's production made India go in for T-90s from Russia.

First, an order for 310 T-90s was placed with Russia and it was followed up with 330-tank order in 2006. Again, in 2007, another order for 1,000 tanks was placed.

While the first 310 were bought directly from Russia, the rest of the orders were for licensed production of the tanks within India.

The licensing issues were only sorted as recently as last year, with Russia agreeing to provide all technical knowhow to India for indigenous production of the tank.

In all, India would have about 35 regiments of T-90s in its armoured fleet by 2020.

Looks like no more Arjuns for the IA even if it kicks the Bhisma's ass in the comparative trials.Why hold the trials at all then i pray?

[sayareakd]

Guys it is bit strange that comparative trials of the tank should have done in June in the rajasthan plans, which is the ultimate test of Indian tank.
It is not clear as to how this test will be perform, as far as name suggest each tank will be compared to the other tank.

few years ago when the DRDO suggested comparative trials, DGMF wanted few of Arjun tanks to be pitted against the few of T 90 tanks, as this trial was held after the induction of Arjun tanks into the IA and choice of time for the trials, seems fishy, but what ever the time or method of trials, i am sure that Arjun will come out top of T 90.

BTW their were reports earlier that Fire control computer of the T 90 tank was unable to take june heat of Rajasthan and the heat inside the T 90 was so much that driver of tank fainted. (it appears for this reason tank trials were held in May, slight advantage in favour of T90 already).

But Arjun has got it own merits, it the trials are free and fare, let the best tank win the trials.

(but guys dont underestimate the power of vokta)

 

[neo29]

Its so clear, some section of the indian army and every the government want to kill the arjun becoz it threatens t-90. these are the people who are in the russian payroll.

even if arjun beats the t-90 in the tests , still these people will bring some issues to stop arjun project.

 

[sayareakd]

:tank:

even if arjun beats the t-90 in the tests , still these people will bring some issues to stop arjun project.

here is what the lollipop, which the DGMF has already given

The army, however, has made it clear that it will buy no more than the 124 Arjuns it has contracted for because it is unhappy with the tank on various counts. This apart, the army says the Arjun can at best remain in service for five to 10 years while it is looking 20 years ahead and needs a futuristic MBT.

Probably what they failed to say is that T90 dont even meet their own requirements. IA want to have T95 to derail Arjun, how pathetic excuse by the DGMF. :thumbs_thmbdn::thumbs_thmbdn:

 

[firechameleon]

maybe they wanna save money by not buying arjun so as to invest it in the tank program with russia......:clever66:
