We have been over this discussion time and time again. T-90A or the specific version India has, the T-90S is a very good tank. At the time it was rolling out of the factory in Russia, Arjun was plagued by a multitude of problems and technical deficiencies. It had an old analog electronics system which was upgraded only in 2005. It could not pull a mine trawl. It also had other issues that come with tank development and which we necessarily do not know of. For eg: There have been engine failures during AUCRT trials which meant the Arjun saw 4 engine changes within 1000Km, which is bad. This is just one of them. In 2005, an imported rangefinder failed in the desert heat and the tank gun could not get enough targeting information to fire its gun.
My question is whether the T-90 was put through the same kind of stringent evaluation done for arjun?
Were the T-90's electronics tested for rajasthan's desert condition?
T-90s sighting system and thermal imaging system too failed in the desert.
Whether the loss of power in desert condition deemed acceptable then?
Whether an international tender was put in place?
Since the army insisted on 4 men crew tank why it did not invite a global tender like MMRCA and evaluate all options before buying T-90??
SO when a 1000 tank order was put in place T-90 was nowhere a finished product in fact it had as many problems as arjun.
CVRDE has taken time to fix these issues and came out with a successful, ready to induct Arjun in 2010. That's nearly 13 years since the T-90 came out. So, by the time the Arjun was ready we know that the technology on this machine was behind the T-90 in many aspects, like the armour, gun, ammo etc. This was established on this forum itself, using open source information. Considering the T-90 was chosen 10 years ago, it made no sense to induct a tank like Arjun a decade later. So, the production was capped at 124. This was called, as we all know, the Arjun Mk1.
CVRDE had taken time out and fixed arjun's problems even without an order for single tank fmo the army.
But have the russians fixed all problems of T-90 even after getting a 1000 tank order which even the russian army has not given for T-90.
No .The T-90s were shipped with all the faullts in thermal sights and without heat hardening of the electronics.In fact when it arrived it was no where near the specs of GSQR set for arjun.It was not even tested like ACCURT trails done for ARJUN.
Army knew the shortfalls of the machine and technology behind the T-90,that's why it gave an entirely different type of specs to arjun.
But the mystery is no international options like leopard or leclerc which were close to ARJUn's GSQR were explored through international tender.No comparitive trials were held.In fact army was so reluctant to push for the comparitive trials between arjun and T-90.The CVRDE went to the extent of third party audit foor ARJUN.
Whether ARJUn is ready in time or not, the procedures followed in the purchase of T-90 is not world class.
the same can be said about the procedures followed in the Jv of FGFA, releasing funding without seeing the first prototype even after excluded from the design phase.
The Arjun Mk2 was mooted with various modifications to a lot of aspects like armour and electronics, including a APS. According to open source information, we do not have any information on the Mk2. So, we do not yet know how it stacks up against the T-90S or the latest T-90 iteration, the T-90MS. Whether the IA considers the T-90MS superior to the Arjun Mk2 or not, we do not know. We do not even know if Arjun Mk2 will be ready within the same time frame as whats required by the Army. But what we can say is that if the flaws on the Arjun Mk1 is fixed on the Arjun Mk2, add the new electronics to it and it should be better in many aspects than the, now 15 years old, T-90S.
The arjun mk-2 has additional capabilities, it was not ordered because the mk-1 failed to fulfill the original specs.In contrast the T-90 was bought as it was offered by russians with no evaluation process carried out.The questions are whether the T-90is battle ready even today with respect to the original GSQR given for ARJUN.
Now, if you want to "guess" which of the tanks is superior, T-90MS or Arjun Mk2, we have very little information going that allows anybody to compare the two. So, there is no point in getting into it. All we know is the T-90MS is a lighter tank, IA crews are well trained on the T-72 and hence the T-90, including maintenance. IA also has the infrastructure ready for the T-90S. We also know that current gen ammo is better on the T-90S than what's available for Arjun Mk1 (open source info). We also know new ammo is being made for both tanks today, but we do not know how good these new shells are. We also know that the T-90MS would be cheaper than the Arjun Mk2 considering Ajai Shukla's article states 346 T-90MS will come at 10000 Crores which equates to 28 Crores for a T-90MS while Arjun Mk2 is expected to cost over 40 Crores per unit according to CVRDE. So, considering these aspects the T-90MS has the obvious advantage over any tank, let alone the Arjun. Now, if we merely extrapolate the T-90MS being as good as the Arjun Mk2 in terms of propulsion, armour, gun and ammo, then all advantages fall to the T-90MS.
According to MOD report submitted to parliament the ARJun was superior to both T-90 and T-72 in'
1.mobility,
2.Firepower,
3.Accuracy in firepower resulting in a much better first kill probability,
4.The best tank in IA.
it is surprising that people say they know nothing about arjun.
If we say the Arjun Mk2 is better in terms of firepower, protection and ammo, even then the numbers being inducted is too small to justify a heavier Arjun force, regardless of being deployed in the mountains in the North East. The only aspects we know for sure is that the T-90 has the better gun and engine because the Arjun will continue with the same rifled gun and 1400HP engine even after the weight upgrade while the T-90MS will have a new engine to make up for the weight upgrade.
According to genuine reports available Arjun is superior to T-90 in firepower, range, accuracy and lesser ground pressure.if you keep on giving smaller orders for arjun it will never mature as a product.
If we consider the Arjun will further develop into the Mk3 and find itself as a replacement for the old T-72s after 2020, then that is an entirely different topic for discussion and completely out of the scope of anybody here. I am pretty sure it is currently out of scope for both the Army and CVRDE too, as it stands today.
He had no idea about Arjun tank, still he made up his mind that it is useless tank. This must be foreign maal mentality.
