T:90 Bhisma

The T90 Bhishma is an Indian variant of the Russian T90S tank. It is tailored specifically for Indian terrain with assistance from Russia and France. With the exception of a few components, it is similar to the T90 line of main battle tanks

Hence most of the information given about the T90 Bhishma will be of the non-export model.

The details of the T90 Bhishma will be useful in the Science and Technology segment of the IAS exam

Brief History of the T90 Bhishma

India purchased about 310 T-90S tanks from Russia. Out of these, 124 of them were delivered in their entirety while the remaining 186 were to be assembled in Indian domestic plants. The objective was to begin domestic production.

The T-90 was selected by the Indian defence establishment because it was a direct successor of the T-72. In fact, the T-72s used in India had most of its parts produced domestically. At least 60% of the T-72 parts had much in common with the T-90. This made service and training of new crews an easy task.

It includes lethal armor-piercing fin-stabilized discarding sabot (APFSDS) and barrel launched Refleks anti-tank guided missiles. On the other hand, the T-90M tanks have a more versatile main armament and can fire several different types of munitions.

These include high-explosive anti-tank (HEAT-FS), and high explosive fragmentation (HE-FRAG), and armor-piercing fin-stabilized discarding sabot (APFSDS) rounds, as well as guided anti-tank missiles.

What’s more, India was keen to purchase the T-90s because of delays in the production of the domestically produced Arjun main battle tank as well as a counter to Ukrainian-made T-80 tanks deployed by Pakistan.

By 2021, the Indian Army had sought to upgrade its existing fleet of T-90s with locally designed modular Activation Protection, with soft and hard targeting kill system, thus updating these tanks to fit modern standards.
