The tank is still largely the same since for close to a decade, whatever touchups there was is not enough to really be worth mentioning. There is no added capabilities or features that would suggest there was enough significant improvement made worth mentioning. BMC like the corrupt ineffecient nepo company that it is, has basically contributed nothing. Within that time frame we could have already build the next Altay variant with unmanned turrets or added firepower. A product usually evolves over time based on feedback and newly available technology. "Yeni Altay" is just a nice propaganda name, and concencus for the most part agree with me on this.
We are basically forced into making a tank that was cutting edge a decade ago, and whilst its still extremely capable and more then enough to the threats we might face, having that technological edge is imperitive to have. Usually when something enters service it should be viable for decades to come, but by 2016 the German KF51 was also announced and shown.
I am not frustrated with the tank itself, its still top tier and very good by all metrics, but moreso around what little has been done with it considering the nearly decade of waiting for engine. The best we got was hilariously a mock-up Altay turret bolted unto a Leopard2A4 chassis.
