The first two Isometric Intermediate Update 1s (IIU1) have been completed and the ships, Cambrian and Eocene have returned to service. The DDS Fleet have reported they are very happy with the upgrade which includes improved sensors, communications and weapons. Another change, little reported up until now, is a major update of the Isometric's mainframe's operating system. This apparently has yielded major improvements in system response time.
3106 Carboniferous (which also has received a refit following it's long mission against the Rectoids) and 3118 Quaternary are now undergoing the update. The DDS hope that all the Isometric fleet will be at IIU1 standard by the end of the year.
