The Clones have switched production to the Z7E version of it's J55 Destroyer tank. The Z7E is a fairly modest upgrade, the Clones decided not to build the final Dino funded version the ZDM3 for themselves a few years ago.
The Z7E has LED lighting, engine modifications to improve fuel economy and improvements to the radio system. The Clones have increased production rate and intend to replace the 2,000 oldest J89s with new build J55Z7Es
