Iran has made new changes to the Chieftain tanks that are currently in their arsenal, the Russian newspaper Rossiyskaya Gazeta reported this week.
The most significant change to these combat vehicles is the replacement of the L-60 engine with the 840 hp. The 840 hp engine comes from the Russian-made T-72S tanks, which are currently in the arsenal of the Iranian Armed Forces.
The old two-stroke engines are often criticized for significant shortcomings that appeared during operations. As it turns out, they are not well equipped to work in desert conditions and overheat a lot. In addition, due to various issues, there are problems with spare parts.
