Possibly as a result of DDS moves to develop its own tank the Clones have reversed a policy over the last few years of neglecting (and withdrawing) its cutting edge J89 main battle tank in lieu of concentrating on the adequate though cheaper J55Z.
While new J89s will not be built around 450 of the existing J89 fleet will receive an upgrade over the next couple of years as the Clone Army seeks to improve its "elite armoured core". The upgrade, known as J89FEA, will only be performed on the final model J89F and FSU, and will include a new improved gun, updates to the fire control system, active EW defence systems and gravo-spatial navigation (this uses the planet's own gravity field for navigation thus cannot be jammed).
The J55ZDM will not be neglected, new build and around 300 of the most recent built will also receive gravo-spatial navigation and the active EW defence.
