Tank T - 59, which has been in use with Pakistan Army, is being upgraded under a phased programme since 1990. After having completed 1st phase of upgrade in1997, the 2nd phase has been launched in 1998 with a total of 50 upgrade features, which have given a quantum technological leap to this old tank.
Owing to their large population, Pakistan Army can not afford to discard / phase out all T-59 tanks therefore, 3rd phase upgradation was planned to be implemented to keep these tanks operationally and technologically compatible with the modern tanks in use with our adversary.
CONCEPT
It is envisaged to utilize stretch potential of T - 59 tank through upgrade in fire power, mobility and armour protection at a fraction of the cost of a modern main battle tank.
PROGRESS
Three prototypes were developed on the above-mentioned concept and subjected to extensive user / technical trials and the selected version has since been in production since year 2003.
Presently the requirement of the Pakistan Army is being met in totality.
EXPORT POTENTIAL
Owing to a cost effective upgrade many countries have shown keen interest in the project and in some cases it is in an advance stage of negotiations.
Specification
MODERNIZATION PARAMETERS
As an R & D project three prototypes were prepared with a view to incorporate the following :-
§125mm Smooth Bore Gun
§700 HP Engine with compatible power train
§Compatible Gun Control and Fire Control System
§Add-on Armour / Explosive Reactive Armour

Description
Up-gradation / Modernization of Tank T-59
REBUILD / UPGRADE
HIT has been rebuilding Tank T-59 since 1979 and has now acquired a high level of expertise in this field. Rebuild envisages stripping of tank to its last nut and bolt, replacing worn out components with new ones and rebuilding the remaining ones to original manufacturer’s specification. This task is carried out with the help of elaborate machines, tooling, and test equipment by highly skilledengineers / technicians. HIT has over the years achieved an indigenization of almost 70% by value and over 85% by variety which has helped lower costs significantly. Besides, some of the most sophisticated electronic system like fire control systems and gun control systems has been indigenized. This is the initial phase of upgrade which was taken up as a progressive plan.
MODERNIZATION
In order to ensure that Tank T-59 keep pace with technology battlefield requirements, HIT under took to upgrade these tanks to the T-59 MII configuration during 1998. This programme is well under way and the tanks have been equipped with a total of 50 features / improvements including :
§TI Sight
§Upgunning to 105 mm Calibre
§580 HP Engine
§Bi-axis Stabilization
§Integrated Computerized Fire Control System
§Auto Fire Extinguisher System
