HAHAHAHHAHA ...........now T 90 & its worshipers need the help of media to justify its survival in IA. Now we have to learn about firing accuracy & night vision capability from NDTV fiction writers. excellent developements, I just luv it. By the way kunal,do u think T 90's can shoot at tgt while moving at 50km/hr speed? I heard i cannot?

Depends on the range..
T-90S Fire control system is of T-80s and its good not good as Arjun but good compare to T-72M1s..
50m-500m it can shoot with good accuracy on move but again it depends on the gunner, And it cannot shoot at 50km/h but 30km/h on rough/sand terrains..

Btw, Our tankers used to shoot on move on T-72m1 at ranges 50 -300m.. :D
Now with T-90S FCS they can shoot to 500m during day..

Just to prove your point here is a related report...

Russian-built T-90 tanks' thermal imaging system flawed

Army suffers an estimated loss of Rs 620 crore

BY Ritu Sharma
Delhi


The Indian Army has detected flaws with the thermal imaging system of the Russian-built T-90 main battle tanks (MBTs), inducted in its fleet three years ago, causing an estimated loss of Rs 620 crore.

Rechristened as 'Bhishma,' T-90s' flaw came to light during its comparative trials with the indigenous MBT Arjun during peak summers in the Thar Desert of Rajasthan.

According to the report submitted by the Indian Army, the French Catherine thermal imaging (TI) camera giving T-90s its night vision capability and higher precision is not "adequately tropicalised." It simply cannot function in the extreme condition for which it was supposed to function. Because of this the thermal imaging camera is prone to malfunction in extreme temperature conditions of Rajasthan, where it is deployed.

"During the trials it was observed that the temperatures inside the tank goes up to 55-60 degree Celsius resulting in the blurring of images taken by the camera," a senior Indian Army officer told Financial World on condition of anonymity as he was not authorised to speak to media.

Following the repeated delay in the MBT Arjun project, the Indian Army had opted for Russian-made T-90 tanks to counter-balance Pakistan's acquisition of Ukraine-built T-80 tanks. Majority of T-90s would be deployed in the western sector bordering Pakistan, where mercury soars to intolerable levels during summers.

The report describes the thermal imaging cameras as the 'eyes' of the tank. While the tank costs around Rs 12 crore, each of these systems cost (including) Rs 2 crore. Prolonged use of the tank in extreme weather conditions has already rendered 80-90 of such systems "unserviceable."

The Indian Army is deliberating to get a locally effective air conditioning system for the thermal imaging camera. However, nothing concrete has happened on this front.

French defence major Thales Land and Joint Systems had signed a contract with Russian Rosoboronexport to supply Catherine thermal imaging cameras for T-90s in 2007. The camera operates in the 8-12 micrometre infrared frequency band and is designed to be retrofitted into existing main battle tank fire control system. Russia started licensed production of the cameras earlier this year.

This is not the first time the T-90 project has run into problems. In 2001 India had contracted for 310 T-90 tanks for Rs 3,625 crore. Out these 310 tanks, 124 were purchased off the shelf, while the rest 184 were bought in semi-knocked down conditions and were to be assembled at Heavy Vehicles Factory (HVF) at Avadi in Tamil Nadu. There was a follow-on contract for 330 T-90s.

Under the contract, Russia was to complete transfer of technology to India for indigenous manufacturing of 1,000 T-90s at HVF by 2006. However, following chronic delay in technology transfer the first indigenous T-90 tank rolled out of the factory only in 2010.

Earlier, lack of cooling systems inside the tank led to uninhabitable temperatures of 60 degree Celsius. This made the Indian Army scout for an air conditioning system for the tank. The fire control systems of T-90s also suffered malfunctions on various occasion.

they had that problem since 2001 its nothing new these are things that make public suspicious about conspiracy against Arjun MBT. Btw does anyone know what happened to the Air conditioning system that was to be integrated to T-90

Belarus was supposed to install a cooling unit hooked up to the APU for the Peleng sight. Doesn't make much sense to install AC just for the thermal when a smaller unit can do it.

yeah kunal sir is right, problem is who is elegiable for AC mindset, even if army allow it MOD babus will reject it.

Perhaps a desert cooler type would be better alternative that will be allowed as per rules.

I doubt the T-95 is particularly feasible. Even Russian Army have expressed interest in a smaller and more lethal tank. No one in Russia is complaining.

What does India bring to the table that Russia doesn't already have? The modern technologies Russia lacks are mainly the ones being imported into Arjun Mk2. Auto-transmission, powerpacks, thermal imagers, bigger engines, BMS and so on. What exactly has India brought to the PAK-FA project yet except cash?

I don't think anything is being imported for Arjun. Only one journo has claimed that. None of the other media houses have reported anything even remotely close to what was claimed in the other thread.

Expect Arjun Mk2 to have a decent indigenous component including transmission, engine and tracks.

Anyhow to answer to your post, most of the times cash is all that matters.

T-95 design specifications are currently unknown, so there is no way to know how we could contribute to the project even if the design reflects what the army desires.

As for PAKFA, time will tell as to what we have contributed to the design.

However let's not go off topic. T-90 is more interesting than PAKFA, T-95 or Arjun.

We already know what Arjun Mk2 will be importing. Unless you have something which refutes FORCE magasine... of course you don't as usual.

Cash means nothing if you don't have the technology.

The specifications don't matter when we know what Russia lacks in technology. Auto-transmission, high grade power packs, modern engines, BMS, thermal imagers, and radios. There is a reason top Russian generals called the T-90 a "17 second modification" and a "heavily modernised T-34." It is an obsolete tank with technology Russia doesn't have to upgrade. That is why they turn to France.
