The Indian government's decision in June this year passing a $500 million upgrade of 300 T-72 Soviet-origin main battle tanks (MBTs) of the Indian army is finally being implemented.

And it is a bargain. The Kharkiv Morozov Machine Building Design Bureau (KMDB) of Ukraine has offered to modernise the entire 2,000-strong fleet of T-72s at approximately 25 per cent the cost that the Indian government paid for 310 T-90 tanks that it had contracted from Russia in December 2000.

In a presentation made last month in India, the Ukrainian defence team is understood to have offered to upgrade 300 of the T-72s over a period of five years (at the rate of 60 tanks per year) to bring about the following improvements: upgraded 125 mm guns; engine improvements to increase horsepower from 850 to 1,000; better land navigation systems; nuclear, biological and chemical protection equipment; laser warning systems; thermal imaging systems; night vision devices; and frequency-hopping radios.

An unspecified number of the T-72s are also to be equipped with "Arena", a state-of-the-art Russian defensive aid suite that mounts a multidirectional millimetre wave radar system on a tank's turret to detect incoming missiles.

An official of the KMDB claimed that the modernisation package offered by Ukraine would match all the important features of the Russian T-90 tanks.

The Ukrainian KMDB builders of the T-34 tanks (of World War II vintage) have also designed and built the T54/55 and the T-59/69, besides T-64 tanks, the immediate predecessor of the T-72. The latest MBT developed by the company was the T-84, which was accepted for service by the Ukrainian Army in 1999.

The company's "superior claims" for the Indian contract rests on this argument: that the T-90s would have been even more identical to the T-72s had the designers not substantially adopted some of the advanced features of the T-80 series of tanks (designed and developed by the KMDB). These features are said to relate to the areas of defensive aids systems and the fire control and explosive reactor armour systems.

The Indian defence establishment has also begun sorting out proposals received from various subcontractors for the T-72 upgrade. Three companies have made a bid for a contract for the improvement of the fire control system: PCO-Cenzin of Poland, El-Op Electro-Optics Industries Limited of Israel, and Thales of Paris. Kerametal of Poland is angling for the power plant contract. The companies that want to sell land navigation systems are Israel's IAI Electronic Group, the German LITEF GmbH and the South African Reutech Defence Limited. In the race for the supply of radio sets are GEC Marconi Electro-Optics of the United Kingdom and Tadiran Limited of Israel. The firms shortlisted by the Indian government for thermal imaging systems for the tanks include Israel Military Industries, the UK's AVIMO and Thales of France.

There are plans that the modification of the gun control systems of the T-72 tanks would be undertaken jointly by the state-owned Bharat Heavy Electricals Limited (BHEL) and the Electronic Corporation of India Limited (ECIL). The night vision devices are to be supplied by Bharat Electronics Limited (BEL). The upgrades, meantime, are to be carried out at the state-owned Heavy Vehicles Factory (HVF) at Avadi in Tamil Nadu.

For lack of funds, the T-72 upgrade programme has been hanging fire since 1991, when the Indian army first put up a demand. A certain urgency arose regarding these plans following the acquisition of 320 T-80 UDs by Pakistan between 1997 and 1999. Latest reports are that Pakistani-built Al Khalid MBTs are also set to enter series production.

India has an inventory of about 2,000 T-72s, 1,500 of which had been purchased from the erstwhile Soviet Union between 1970 and 1985. The remaining numbers were built under licence in India.

A senior services official said that that improvements in the T-72s have been conceived to provide them a new life, which will also allow the Indian army to phase out the less capable Vijayanta and T-55 tanks by 2010. Within the Indian, there is even a view that the T-72 upgrade plan ought to have taken precedence over the T-90 purchase deal: the former would have been a cost-effective option.

lets wait for the details to come out. Then one can comment on how the upgraded T-72 fare against al-zarrar. Though I have my serious doubts regarding arena.

I guess Avadi is either too busy doing something else... meaning nothing or is not capable of performing any upgrades except putting kits together from Russia....

In Anyway, If 300 tanks are taking 5 years then by the time they are done with 2000 tanks it will be over 15 years.. correct me if I am wrong. Question is if India is sending these tanks to Ukrain or these upgrades will be done in India at Avadi.... in any case upgrading 2000 tanks is not an easy task.

I suspect that they will keep "talking" about this for a few years before there is any movement on the decision itself. Case in point, Aircraft Carrier... AJT... Weapon Locating Radars... etc..

What upgrades were made to Al-Zarrar?

There are a lots of ifs and buts in this deals. It seems that the tanks will be undergoing major changes and the Ukrainians will be providing CKD kits for upgrade. The chassis will remain the same. However, what I cant understand is that why India is going the Ukraine way. If I recall correctly, India had put a lot of pressure on Ukraine when Pakistan was finalizing the T-84 deal. They said if they provided tanks to the Pakistanis then Ukraine should forget doing business with india. Then why are they coying up again. The same upgrade is also done in russia and the last time mr. vajpayee was there they talked about it. Then why are the keeping russia out of the deal??? This looks really strange to me.

Another thing is that why are the Indians not using their own radio sets? I am quite sure they manufactre their own radios for the tanks. Even Pakistan makes its own radio sets for personnel and vehcles. and when they take the name of tadiran, this company is very famous for their Frequency Hopped CDMA sets. I guess that is what they are going for.

Rakesh,

These are 'some' of the upgrades that al-zarrar will be having.

Installation of 125 mm Smooth Bore Gun of T-80UD origin with semi auto loading mechanism through major modification in the turret and Gun Control System.

Installation of 730 HP engine (T-85 type) with upgraded suspension.

Image Stabilized Sights (3-axis)

Upgraded Fire Control System with multiple target engagement capability.

Next Generation Theramal Imaging

Enhanced armour protection through add-on armour, Antimine Bottom Plate and explosive reactive armour.

The best part is that all these modifications will be done in Pakistan, by Pakistani people and using mostly Pakistani equipment (Except Engines). However, for engines I can tell you that for T-59/T-69 overall. 89% percent of the engine components (by value) are made locally in Pakistan.

Cheers,

Christopher F Foss of Janes Defence Weekly said. The part of Pakistani Type 59 MBT fleet has already been upgraded to Phase I (500) and Phase II (300) configurations. The Phase III Al Zarrar is the most ambitious upgrade ever attempted on the Type 59 MBT or its Russian equivalent, the T-54, and it has now been disclosed that three different prototypes were built for extensive user trials: Prototype 1 is fitted with the 125mm smoothbore tank gun (as installed in Pakistan’s T-80U MBTs); for this application the turret has been raised 100mm off the chassis. A new powerpack has been installed that includes the Ukrainian 5TDF five-cylinder diesel, developing 700hp. It shares many common components with the 6TD-1 six-cylinder diesel, developing 1,000hp, which is already installed in the 320 T-80UD/T-84 MBTs recently supplied by the Ukraine to Pakistan.

prototype 1The suspension of Prototype 1 has been upgraded and reinforced to allow for the higher combat weight of the vehicle. This includes the installation of stronger torsion bars. The vehicle is now fitted with track return rollers and new double-pin tracks with rubber pads have been installed. Battlefield survivability is enhanced by the introduction of additional passive armour to the turret with a fully enclosed stowage box now being installed on the turret rear. Explosive reactive armour (ERA) has been installed over the frontal arc. A new fire-control and sighting system has also been installed.

Prototype 2 retains the 100mm gun of the Type 59 but is fitted with the V46-5M 12-cylinder water-cooled diesel engine, developing 690hp, coupled with a modified manual transmission. The suspension has been improved. For increased survivability an anti-mine bottom plate has been installed and ERA can be fitted.

Prototype 3 features the powerpack of the NORINCO Type 85-IIAP MBT with the suspension upgraded. The 125mm smoothbore gun of the Type 85 has been installed. The fire-control system consists of image-stabilised sights and an upgraded computerised fire-control system. Armour protection is the same as Prototype 1. As the 125mm smoothbore gun is not fed by a fully automatic loader (as installed in the Type 85 and Al Khalid MBTs), the upgraded Al Zarrar MBT retains its four man crew, consisting of commander, gunner, loader and driver. The 125mm ammunition, already manufactured by the Pakistan Ordnance Factories (POF) is of the separate loading type, projectile and charge with its semi-combustible cartridge case.

All upgraded vehicles retain the 7.62mm co-axial and 12.7mm anti-aircraft machine guns and have a bank of electrically operated smoke grenade launchers either side of the turret firing forwards. Different sources of key sub-systems also allow for increased competition. The ERA, for example, could be supplied by NORINCO or from two sources in Pakistan, Dr A.Q Khan Research Laboratories or the National Development Complex (NDC).

The final Al Zarrar configuration for production is now being decided and it is expected that the user will select the sub-systems in the first half of 2001 and that production will commence in July 2002. It has also been disclosed that HIT has built a batch of 45 NORINCO Type WZ 653 armoured recovery vehicles and proposals have been made to upgrade this vehicle to enable it for recovering the heavier Al Khalid MBT. The Type 653 ARV was originally developed to recover the Type 59 and Type 69 MBTs but the Type 85-IIAP and Al Khalid are heavier.

Just a small correction, The engine installed in T-84 is 6TD2 (1,200HP) not 6TD1 (1,000 HP).
