The principle tank in the HCS, the T-89, is to cease production when the current order for new build T-89FSU2 ends later this year. This will bring to an end several decades of continuous tank development and production that began with the T-86 in the earliest days of the HCS before progressing to the T-88 which was the mainstay of the wars with the DDS and finally to the current T-89.
The HCS has decided to only build T-55ZDMs which were co-designed with the Dinos from now on though will continue to maintain and update it's huge fleet of T-89s for the next decade at least.
