The RAN Hobart class are "full Aegis" ships. The additional systems are for functionality not included in AEGIS, similar to use of AN/SQQ-89 by the USN.I don't have the answer for the CTI acronym but it looks like a replacement for CMS 330 as that's the system is being rebuilt to accomodate Aegis somehow.
There is a scale. On one side is a full CMS 330 ship. On the other a full Aegis ship. Somewhere between those two will be the CSC full combat management system. The Aussies already did this with their CMS in the Hobarts, where it uses some Aegis stuff combined with the 9LV system (from Saab).
Where that ends up for Canada is still a bit unknown ATT. CMS interface with Aegis programing? CMS underwater warfare with Aegis air defence? Different servers, Aegis software in a CMS server, vice versa? I know Canada is liasing with Australia on how they accomplished this and what their lessons learned are though.
There is a better view of this thing and I still don't know what it is.
